Why the external block of air conditioner hums, noises, crackles and what to do
Why the humming of the outside air conditioner and how to fix it? Every air conditioner owner at least once asks this question. Some people immediately rush to call a master and pay him for what they could do yourself.
There are many reasons of noise, crackling and humming of outside air conditioner unit. It is possible to get rid of many of them by yourself. In this publication we will tell you about them.
Appearance of noise and how to avoid it
Budget models of conditioners initially work louder than expensive ones. This is due to the fact that the quality of assembly and the materials used lags behind. Sometimes these problems can be solved, but not always.
If you have decided to buy split-system, you should get acquainted with its characteristics. Pay attention to the heating and cooling sound levels. they can be different. Compare this index with the following:
- Conversation: 40-45;
- Office: 50-60;
- Street: 70-80;
- Factory (heavy industry): 70-110;
- Chain saw: 100;
- Jet Launch: 120;
- Vuvuzela bell: 130.
If after a routine diagnosis or service there is a strange sound, something is obviously done wrong. Some “craftsmen” may say that over time, the outdoor air conditioner unit will stop making noise. don’t believe it! Demand that they eliminate the cause of the extraneous sounds.
If the outdoor unit of the air conditioner is constantly making noise, but the sound is amplified. you may not notice it. But the longer there is a problem, the harder it is to solve. So periodically pay attention. isn’t your air conditioner too noisy compared to others?

Rubber anti-vibration mounts for external unit
Experienced installers know how important it is to install vibration isolation products. They prevent the transmission of vibrations through the metal to the enclosing structure. By design, they can be rubber and spring-loaded. Rubber, natural vulcanized rubber and other polymers are used as a material for making dampers. Inside the elastic shock-absorbing element there are two bolts or one stud, used for fixing. Damper rubber has excellent vibration-damping characteristics. Its structure contributes to the attenuation of waves. The material is resistant to aging and wear and does not crack during use. Advantages of the product include:
- moisture resistance;
- operating temperature range from.40°C to 70°C;
- withstands short-term exposure to acid and oil;
- It is possible to adjust the height of the support;
- Universality. products are suitable for any models of split systems, the main thing is to choose the right load.
Vibration mounts are made in different shapes: cylindrical, truncated cone, round.
With other designs, the main part is the steel spring. It smoothes low-frequency vibrations. Polymer plates are rigidly attached to the end coils of the element. The spring can be placed between steel discs coated with thermoplastic. This design protects the internal mechanism from moisture and contamination.
There are several important factors to consider when selecting an anti-vibration support for an air conditioner’s outdoor unit:
- load. the products are designed for a certain weight of the air conditioner;
- characteristics of the product material;
- vibration absorption capabilities.
Parts differ in color, it depends on the dynamic load applied.
High quality anti-vibration mounts for air conditioners are made by: Tecnosystemi, Soleco. Italian brands offer antivibration mounts with possibility of regulation, designed for high weight up to 150 kg per item. Soleco vibration isolators are made of galvanized steel and practical elastomer. They are resistant to ultraviolet light, weather conditions, organic fats, provide electrical insulation. Parts have hole for M8 stud, model color shows permissible load.
Vibration pads between the wall and the brackets
The rubber gaskets between the bracket and the wall reduce noise
The mounting location of the outdoor unit and supporting elements of the bracket have special requirements in terms of strength. They must be capable of supporting the weight of the unit. In panel buildings, vibrations from machinery in operation can be transmitted to neighboring apartments. The isolation of the bracket post from the wall surface will help to avoid conflicts and the gradual destruction of the building envelope. Put a rubber gasket between the two elements.
Vibration mounts under the feet of the outdoor unit of the air conditioner
Vibration absorbers for outdoor units or silent blocks for the feet are designed to dampen the vibrations of medium and high frequency. They are installed between the air conditioner and the metal support strut. Included with a set of four vibration dampers comes 8 washers and nuts made of galvanized steel. Other fasteners allow to reduce the vibration level. Dampers are available as rubber spacers with a hole for an M8 bolt.
The installation of antivibration mounts for air conditioner is the most simple and available way to avoid the noise level during the operation of climate equipment.
Vibration mounts for the outdoor unit of the conditioner. what to replace?
Afternoon. Is to install two air conditioners for the apartment (one. on a bearing wall made of brick. under the window, the second. on the surface of the balcony, on the balcony outside a metal profiled sheet from the builder and inside the balcony lined “wall” of sybite). Looking for vibration mounts. Vibration absorbers, vibration-damping pads for the outdoor unit of an air conditioner. But all sites. there is nothing in Novosibirsk. What can be substituted? The company. where the air conditioners are bought, and will be installed, does not offer anything like this. Thanks.
If you understand one thing, you will understand eight.
Slightly stiffer, but they work, urethane supports from all kinds of cars.Bolt through mount. more reliable, the unit can not fall, even if the destruction of supports, in the photo below, the moult on three heads and polyurethane mounts from Sable.
There is also a part like this, already with a metal inner sleeve, worse? Vibration will be transmitted?
KATRAN. Please tell me what is “MULTI for 3 Heads”? What is the name of the black part like a washer??
myremont. Three-head mult is a contraction, one large outdoor unit, designed to work with 3 indoor.Black part as a washer, it is a special washer, bought in the same parts store as the supports.The inner bushing is not needed in this case, it will spoil everything.
KATRAN. Could you tell me please what diameter stud is used and what is the diameter of the hole on the inside of the “pillow?
myremont. I do not remember the inside diameter of the last pads,about 12 mm,m10 bolt.
Here’s my result: shim washers and polyurethane bushing.

KATRAN. Tell me please, what is the “MULT for 3 HOLES”? What’s the name of the black part like a washer?
myremont. If the external unit is not so big and heavy (this unit for three heads weighs 68 kg), then don’t disregard Katran’s earlier advice to use analogous polyurethane bushings from Volga (there were their photos with a cat above.numbers). They are smaller and softer. The black washer prevents the bushing from being crushed when tightening fasteners, there’s a special “flanging” (or outcropping) which, when tightening, pushes the outside diameter of the bushing inward itself, not allowing it to “move apart. Well and the water will flow less. I think this will affect the life expectancy of the bushings

Vibration and hum from the outdoor unit
#1 Simple
Afternoon.There is a problem after installing the air conditioner.In general, put me in two rooms air conditioners, 9-ku Danteks and 7-ku GC.
There’s nothing wrong with the dantecks and the GC makes a vibration and hum when it works. If you touch the window or wall on which the outdoor unit hangs, you can feel a slight vibration of the wall or window. There is a hum in the room with the window closed.If you open the window and listen to the unit, the operation of the unit is not audible in the background of the noise from the street. It is true, if you put your palm on the block, you can feel a slight vibration. The unit of the second air conditioner also vibrates a little, but less.
Installers first said that you need to put rubber spacers between the block and brackets and vibration will go away. We did, but it didn’t help.
Then they said they could hit the rebar during installation and need to re-hang the block a few centimeters to the side.
And they said the wall is not only thin (like 7 cm of concrete, 10 cm of styrofoam and another 7 cm of concrete), but it’s also short (!). That’s why there is a kind of resonance. And maybe we will have to hang the unit on another wall.
I also heard that the fan can be unbalanced and it can also cause vibration. Although installers reject the problem with the block itself at once.
Has anyone encountered such a problem and how to solve it?? What else could be the causes of vibration?
The strange thing is that the block itself doesn’t vibrate much, but the hum is palpable for some reason.

Good afternoon.There is a problem after installing the air conditioner.In general, put me in two rooms air conditioners, 9-ku Danteks and 7-ku GC.
There is nothing wrong with the Dantex, but the GC unit vibrates and hums when it is working. If you touch the window or wall on which the outdoor unit hangs, you can feel a slight vibration of the wall or window. Accordingly, in a room with a closed window the hum is well audible.If you open the window and listen to the unit, the work of the unit is not heard in the background of street noise. Truly, if you put the palm on the block you can feel a slight vibration. The unit of the second air conditioner also vibrates a little, but less.
Installers first said that I had to put rubber pads between the block and brackets and the vibration will go away. We padded it, but it did not help, maybe a little less.
Then they said that they could have hit the armature during the installation and that it was necessary to suspend the unit a few centimeters to the side.
And they also said such a thing that the wall is not only thin (like 7 cm of concrete, 10 cm of styrofoam and again 7 cm of concrete) but also short (!). So there is a kind of resonance. And it may be necessary to hang the unit on another wall.
I’ve also heard that there can be imbalance of the fan and it can also cause vibration. Though installers reject the problem with the unit itself at once.
Has anyone experienced this and how it was solved? What else could be the cause of the vibration?
The strange thing is that in general the block itself does not vibrate strongly, but the hum is somehow perceptible.
but the installers are from the same company where you bought the unit? If yes, of course, they will reject the problem with the unit. even if there’s a problem.
The vibration at the conditioner. Where does it come from? Ways to repair.
There can be many reasons for increased vibration. First you need to open the lid of the outdoor unit and look if the tubes do not touch the casing and if the fan bracket is fixed properly. The tubes bend back, the bracket can be fixed better. Further, if vibration has remained (it is felt strongest at the ports. it is the increased vibration of compressor) then there are three ways to struggle with its transmission on brackets on a wall at once:
Moving the unit to a stiffer wall 2. Replace the brackets with stiffer ones, with a hole not in the center for an anchor or screw, but as low as possible (then the bracket will not “walk” on the wall with the unit to create a hum) 3. Vibration mounts installation with bolt isolation from the bracket through the rubber. Vibration mounts from Copeland are ideal, but they are not a panacea.
The vibration of the outdoor unit
Installed air conditioner. Now when working in the apartment there is a hum. If you put for example a screwdriver on the external unit, you can see how it “jumps”. Is it a wrong fixing of the unit or is it a hidden defect of the air conditioner. air conditioner like www.techport.etc. cl-tac-12chsa-bh ps previous topic delete, it is probably without subject and no one can see
it happens. this is a problem of badly tightened nuts and self-tapping screws in the unit. so you just have to put up with it. This is definitely not a fault of the installers, unless of course you pay for 4500r. installed
Ha!ha! Price is a factor here? Then how’d they get you the ventilation for the price of an underwater mask?? If you don’t understand, don’t give advice.
That’s the thing, when they were installing the second unit next to it, they put a tool on the first one. It was vibrating a lot, even bouncing. I told them something was wrong but they didn’t say anything. But they didn’t listen to the noise inside. I’ll have to call them again.
1.When transporting, the unit is thrown all over the place and it is not uncommon that the pipes inside the outdoor unit begin to snag the compressor.treated by disassembling the unit and correcting the pipes in their original places. 2. The route’s too short.), the vibration along the pipes is transmitted to the indoor unit and it shakes. 3. kinked pipe, too high pressure hence the increased operation of the compressor with vibration.
Sometimes we just dragged it from the car to the apartment. I don’t think so. 2. From the external unit to the entry into the wall of the order of.50-60 cm. Further to the indoor unit 2-3m 3. bent tubing with a special spring. ps I’ll call the director today and have him send an installer.
I don’t know, the director came by and listened to me. Because of this everything vibrates. I put my hand on the outdoor unit and felt no vibration, but the hum in the apartment. Maybe from the indoor unit is such a hum.
Where it hangs external Iznitri foam concrete block. 30cm, insulation, facing brick
Inner block is hanging on the monolithic wall. On the left of it goes out of the line. 30 cm and through 2 holes goes into another room and down from there (1.2) in the cable duct then turns to the right goes 1m and out into the street through two holes
That noise is subjective, too. So I say the director came to listen, said like an empty room and like it should. Nearby is the second unit, but not yet connected, as repairs in the room are not completed. How to finish. I’ll compare if they can’t determine anything.
If you don’t mind, if you pass by. or tell me what else to check. I don’t know where it’s coming from. On panin.
Yesterday we hooked up the second one. The noise is the same as the first. We put rubber rings under each unit. did not help. What other noise reduction measures are available, does anyone know??
If conditioners are cheap, then sometimes it is possible to cure such a problem by replacement of compressors, as now the compressors are installed without any clarity, and most likely they cause vibration.Burned myself on this, when I put myself a cheap Dantex.
The crux of the issue is that the compressor is already on rubber shock absorbers. and there are several options here: 1. During transportation unit fell and shifted the tubes and now they rub and vibrate (90% of cases) or these shock absorbers tightened fasteners on the compressor and it is a lump. Another option, there were many in new houses. Getting the bracket’s fasteners into the cavities of the foam blocks, and there’s a music box. It is possible to escape by hanging up and looking for a hard surface that is not empty.
Vibration from the air conditioner. Hum and noise reduction.
In this article we would like to touch upon such a serious problem, as vibration of air conditioner and reducing the noise, produced during its operation.
Installation of air conditioners. is a process that requires appropriate equipment and components, and the skills of the specialist who performs the installation. Unfortunately the installation is not always done qualitatively, and that causes negative consequences during the exploitation: water drops from the conditioner, strong and noticeable vibration is created.
In addition to poor installation, vibration and excessive noise can be caused:
- A mistake in the design of the air conditioner itself, made by the manufacturer;
- The main reason for this is the factory defect or poor build quality;
- In cheap models often geometrical center of outer unit propeller does not coincide with its center of mass which leads to additional vibrations;
- fan or compressor in the outdoor unit of the air conditioner.
People, who have air conditioner installed incorrectly, often complain about noise, vibration and hum from the walls. It prevents not only from sleeping, but also from living comfortably in general.
One of the easiest ways to eliminate or significantly reduce the vibration of air conditioners is to install special vibration mounts (dampers), which are mounted on brackets, under the feet of the external unit of the air conditioner. In addition, if necessary, vibration mounts can be installed between the brackets and the wall.
Vibration mounts are made of innovative material Megol, which not only provides excellent vibration isolation properties, but is also resistant to aging and cracking.
Read more about all the characteristics of dampeners and make an order for them in our catalog of materials. When choosing a vibration support be sure to pay attention to the weight of air conditioner it is designed for.

Living Room: 17kv.m functions. Or what can be squeezed out of the hall of a typical khrushchevka. Part 1
Good day to you! I haven’t written posts about my renovation in a long time. It dragged on slowly, the money required not a little, but many people wrote to me, they say, “For example, this set of the building, the customer was going to build it. when you finish the sequel, and? Well, here I am, writing 🙂
I want to warn you right away. The posts will be 2, because a lot of photos and text piled up. And in fact, probably. There will be a third post, when, or if, I finish all the decor and beauty. In general, I wanted to write this post at the full completion of the process, but such times are so restless, when it is not clear when in general there will be this bright moment. So I write at 95% readiness.
So, get acquainted. the grandmother’s old living room. Room 5.6m by 3.1м
Inconvenient proportions of the room. Corridor, elongated. Has a door to the balcony, on the plus side. Angular, so a lot of light. But in general. Uncomfortable to design solutions room. Can not be divided into two. Too little space, place furniture. Also difficult, the door to the balcony requires a through passage. Prior to repair, the interior is typical Soviet. On the wall (not visible in the photo) a carpet, a huge, heavy and dark wall Czech, crystal chandelier. Everything is just as we like it.
This was the last room in the renovation. As follows from the posts in my profile, all the other rooms and the balcony were previously done. Room-by-room renovation was chosen as the most budget-friendly option without relocating during the renovation.
As always, I will start with the TK, so that the result is not HZ. I wanted the following:
1)Large. LARGE. Desk. I have always lacked a working area for work and hobbies.
2) Plenty of storage space for tools and materials, electronics and plastics.
3) A place for 3D printers, which I have 3 pcs.
4) Place to rest. Sleeping space for guests, gatherings, watching movies.
1)Simplicity of room geometry by floor. robot vacuum cleaner should not have inaccessible areas.
2)Concealed communications. Pipes, batteries. are not beautiful.
3) the communications must be serviceable. nothing walled up, everything should be able to be maintained.
These are the general wants. The first sketches of the layout show that what is proudly called a “big room” is not really such a big room. I took my time, and over a few trials and a few weeks of painting, realized the design. the project.
Let’s take a look at the design. Functionally, the room is divided into two zones. Living room and working area. The division is realized almost purely by decorative methods. No partitions or screens. just the color of the floor and the breakage of the work cabinets. Space is not enough, any partitions would turn the room into a closet. The living room area is simple. It has a large corner sofa (2.4 meters), which is both a place to rest and guest sleeping place. since the sofa folds out into a large double bed. On the wall above the couch are 2 segmental lights. have both a decorative and working purpose. They can be used for reading or as a nightlight. Opposite the couch. TV. The wall with the TV is supposed to be “green” with an ampel pinwort. It is also assumed 1-2 bags, as additional places to rest.
The more complicated part. work area. Its base is a very large corner table, about 2 by 3 meters, and an auxiliary table in gray opposite. Corner table is combined with the window sill, for more efficient use of space, and is a standard Ikeevsky tables. As a support, the tabletop is cut and spliced in place. Benches under the desk hold things that are always in use. paper, office supplies, art supplies like paints or pastels. The corner table, in turn, is divided into two parts. The left side is for office and art work. PC work, drawing, drafting, and stuff like that, and the right. for soldering, 3D printing, painting miniatures, modeling, and anything else that might contaminate or damage the work area. This part of the table is made by a separate, easy-to-assemble panel. to be replaced if damaged. There are 8 Ikea storage modules hanging over this desk, 60 60 40, and 60 40 40. Stores items for more infrequent use. Storage of hardware, tools, airbrushes, all sorts of things, and the higher the level. The more seldom used things are stored. The first hinged tier is hand-accessible without lifting off the chair. Also, lots of outlets. 5 pcs under the table for PC, 2 pcs on the right working area. for soldering iron, laptop (the right side also plays the role of a guest workstation). The socket in the slope on the left. for charging your smartphone. There is also a lighted desktop. The switch is also in the slope on the left.
On the opposite wall. where the gray tabletop. area to work with 3D printers. All of the lower cabinets under the countertop. space for 3D printers, it is assumed that there will be soundproofing. There are also four power outlets. Tabletop is for printer maintenance, reassembly, upgrade. Hanging levels above the table top. storage space for products, plastic, spare parts. There is also a light for this table with a switch, and a socket just above the table. I wouldn’t say it’s very roomy. Still, the room has a lot of tasks. I would like a light and airy interior, but pragmatism comes first.
Have been able to absorb all this pile of text? I hope so 😉 And, let’s begin. Do you know what the worst enemy is when repairing a room? Dust. It’s a hell of a filthy substance, it’s volatile, gets into the tiniest crevices and spreads everywhere. To all who will repeat something like this, I advise to protect the premises with film and temporary doors, gluing all joints and the inside and outside. with adhesive tape. And try to create negative pressure in the dusty room. roughly speaking, open or close the doors and windows in the apartment so that the film bends inside the dirty room. then you can protect against 99.9% dust.
Types of products
Rubber vibration absorbers under the outer unit
Experienced installers know the importance of installing vibration isolation products. They prevent the transmission of vibrations through the metal to the building envelope. Rubber and spring loaded products are available by design. The material for making dampers is rubber, natural vulcanized rubber and other polymers. Two bolts or one stud bolt are inserted inside the elastic damping element and are used to secure the. Vibration-damping rubber has excellent vibration-damping properties. Its structure contributes to the attenuation of waves. The material is resistant to aging and wear and does not crack during use. Among the advantages of the product:
- moisture resistance;
- Operating temperature range from.40°C to 70°C;
- withstands short-term exposure to acid and oil;
- support height adjustment possible;
- universality. products are suitable for any models of split-systems, the main thing is to choose the right load.
Vibration mounts are available in various shapes: cylindrical, truncated cone, circular.
In products of other design the main part is a steel spring. It smooths out low-frequency vibrations. Plastic plates are rigidly attached to the end coils of the element. The spring can be placed between the thermoplastic coated steel discs. This design protects the internal mechanism from moisture and contamination.
There are several important factors to consider when selecting an anti-vibration mount for your outdoor air conditioner unit:
- load. products are designed for a certain weight of the air conditioner;
- characteristics of the material of the product;
- the ability to absorb vibrations.
Parts differ in color, it depends on the inherent dynamic load.
High-quality anti-vibration mounts for air conditioners are produced by the following companies: Tecnosystemi, Soleco. Italian brands offer anti-vibration mounts with adjustable, designed for high weight up to 150 kg per item. Soleco vibration isolators are made of galvanized steel and practical elastomer. They are resistant to ultraviolet light, weather, organic grease, and provide electrical insulation. Details have a hole for a stud M8, the color of the model indicates the allowable load.
Vibration pads between the wall and the brackets
Rubber vibration pads between the bracket and the wall reduce noise
The mounting place of the outdoor unit and supporting elements of the fixture have special requirements for strength. They have to withstand the weight of the module. If the building is paneled, the vibration from the working equipment can be transmitted to the neighboring apartments. To avoid conflicts and the gradual destruction of the enclosing structure will help to isolate the bracket post from the wall surface. A rubber vibration gasket is placed between the two elements.
Vibration mounts under the feet of the AC unit
Vibration absorbers for outdoor units or silent blocks for feet are designed to absorb vibrations of medium and high frequency. They are installed between the air conditioner and the metal support. Included with a set of four vibration mounts comes 8 washers and nuts made of galvanized steel. Other fixing elements also help to reduce the vibration level. Vibration absorbers are available in the form of rubber gaskets with a hole for an M8 bolt.
The installation of antivibration mounts for conditioner is the simplest and the most available way to avoid the noise level during exploitation of climate equipment.
Vibration mounts for the outer block of the air conditioner. what to replace them with?
Good afternoon. There will be two air conditioners for the apartment (one. on a bearing wall made of brick. under the window, the second. on the surface of the balcony, on the balcony outside a metal profiled sheet from the builder and inside the balcony lined “wall” of sybite). Looking for vibration mounts. Vibration absorbers, vibration-damping pads for outdoor air conditioner unit. But all sites. there is nothing in Novosibirsk. What can be replaced by? The firm. Where to buy air conditioners, and will be installed, does not offer anything like this. Thank you.
If you understand one thing, you will understand eight.
Slightly stiffer, but they work, urethane supports from all kinds of cars.Bolt-through mounting is more reliable, the unit can not fall, even with the destruction of supports, in the photo below moult on 3 heads and polyurethane supports from a sable.
There is also such detail, already with an inner bushing of metal, worse? Vibration will be transmitted?
KATRAN. Can you please tell me what is a “MULT for 3 HOLES”?? What is the name of the black part like a washer??
myremont. A 3 head moult is an abbreviation, one large outdoor unit, designed to work with 3 indoor.The black part as a washer is a special washer purchased at the same parts store as the support.The inner bushing is not needed in this case, it will spoil everything.
KATRAN. please advise what pin diameter is used and what is the diameter of the inner hole of the “cushion?
myremont. I don’t remember the inside diameter of the last pads,about 12mm,m10 bolt.
Here is my result: washers machined and polyurethane bushing.

CATRAN. Can you please tell me what is a “3-HOLE MULTIPLE”?? What’s the name of the black part like a washer?
myremont. If the outdoor unit is not so large and heavy (this unit for three heads weighs 68 kg), then do not disregard Katran’s earlier advice to use similar polyurethane bushings from the Volga (above were their photos with the cat.numbers). They are smaller and softer. The black washer prevents the bushing from being crushed when tightening the fasteners, there’s a special “flanging” (or outcrop) that, when tightening, pushes the outside diameter of the bushing inward itself, preventing it from “sliding apart. Well and there will be less water leaking in. I think it will affect the longevity of the bushings

Max0123. Thanks, that’s what I did, I entered the part number in the online parts store that is in the photo on the package. That’s what I bought. What is the black rubber washer is still a secret to me. Looking through photos of rubber parts for cars to choose similar. But the problem is that we are not motorists, we don’t even know what the real name of the “MULTI ON 3 Heads” is
Noise from the outdoor unit of the air conditioner?
Actually a little laifhak(god-awful word), it is not uncommon that the external unit of the air conditioner is not so noisy, can even vibrate the wall to give. You can get rid of the odor with these, for example, long engine cushions from a vintage car
Great for damping out all the vibrations from the frantic outdoor unit
How long will it last outdoors and will not decay like the ones that come with splits.
If the vibe of the unit goes, the furry beast will soon come to him.
There, in fact, only 2 things can give the vibration.
Fan. Impeller out of balance. Destruction of motor bearings. Anyway, it needs to be repaired.
Compressor. Again, won’t last long if the vibration starts.
vibration damper.and you don’t have to invent anything

For a title like that you should be sent to Antarctica.
It seems to me that the main noise there is from the fan.

and age
When I divorced my husband, I was 29 years old and my mother-in-law, when she heard that her son had left me for another one, sighed indulgently and said.”Yeah, he ruined your life, and you’re already that age. “. At the age of 30, my mother began to shame me for my clothes, namely a light sports style, boots on a rough sole, cotton short skirts. “In my age” should wear everything strict and necessarily below the knee, and certainly about the bright colors should be forgotten. At work, all the deeply married ladies periodically sigh at my 35 and try to talk me into at least doing IVF before I’m 40.
Anyway, after 35 years. You’re a lost cause and you’re at the bottom, especially if you’re a woman.
