Neighbor Complains About A/C Noise: AITA?
Neighbor is upset about the loud A/C unit, but the tenant has tried everything to resolve the issue - what should they do next?
A neighbor complaint about an A/C unit is supposed to be small drama, right? Except in this townhome setup, the noise is vibrating across walls, the landlord is getting pulled into it, and the renter feels like they are constantly walking a line between “being considerate” and “being blamed.”
The OP and their partner live in the second unit of a four-unit building, and the problem started after their A/C was swapped in around October. After the replacement, the left-side owner began saying the unit was “super loud” and shaking their whole house, even though the OP’s own technician checked it and said the compressor was basically doing overtime in winter.
Now, as spring rolls in and the A/C actually gets used, the same neighbor is back again, and the OP is wondering if they are the A-hole for trying to cool off.
Original Post
I live in a townhome that my partner and I rent. It’s one big building split into four units.
We live in the second unit from the left from the outside. We have one neighbor to the left who owns their unit, with the other unit beside us being vacant currently.
We moved in last summer and didn’t have any issues until around October where our A/C unit started malfunctioning and our property manager swapped it out free of charge. After this unit had been installed, our neighbor started complaining to us that it was super loud and vibrating their whole house.
I felt bad at first because I wanted to be considerate and so we scheduled for our A/C technician to come and take a look. For context, we kept using our A/C through the winter because our bedroom, which was on the top floor below the roof deck where the A/C unit is installed, gets really stuffy and there isn’t much air circulating in the room.
We called in our technician after discussing with our property manager, and they had said that the unit was functioning as intended and the compressor was just working overtime since it was the winter time. The tech also mentioned the property manager didn’t pick the most high end unit and is probably why this is happening, but I think thats reasonable.
He also confirmed our need for the A/C saying that our room was a hotspot and lacked any circulation. We also asked the tech to go into our neighbors place, because they asked him to come, and confirmed that what they were hearing was what we were hearing and i noticed that their house was indeed NOT vibrating as they had said.
Admittedly there is a hum, but nothing too egregious and the tech even jokingly asked me “Should we just tell the neighbors to kick rocks?” Our neighbors asked us to not use the A/C since it was still cold out and I agreed to try it out. So we did and it was fine, not great but manageable.
Spring is rolling in and we started using the A/C and they complained again, asking us to call the tech to put in things that would minimize the disturbance. So we did.
We had the tech come in at least 4 times in two weeks to install heavy duty pads under the A/C unit, a compressor blanket, and added rubber washers and rivets wherever possible. Now they’re still complaining, saying they aren’t able to have a good nights sleep because of our A/C etc.
I feel as though we’ve made every attempt within our power to make things better, but every time we do so, it’s not enough for them. I also believe we’re well within our rights to use the A/C in a reasonable manner, and I am also not willing to sacrifice my partner and I’s comfort for their sake by not using the A/C at all.
Short of telling the property manager to purchase a new A/C unit just for the neighbors sake, which I would understand if they didn’t want to, I am out of ideas. TLDR; neighbor complaining about us using the A/C that we need, have made every attempt to better the situation, but they’re still complaining.
CORRECTION: Everybody’s mentioning that we should direct them to our property manager. I forgot to mention that they have been speaking and they do have their number, they simply just keep reverting to speaking to us for some reason
The Power of Perception
The situation at hand highlights a classic psychological phenomenon known as perceptual differences.

It's essential to consider the profound impact that stress can have on a person's sensitivity to external disturbances, such as the noise generated by an air conditioning unit. High levels of stress can heighten irritability and diminish one's tolerance for disturbances. This can lead to disproportionately intense responses to environmental factors, including noise, resulting in increased frustration and conflict.
To address this issue effectively, it might be helpful to focus on alleviating their stress through various means. Community support, such as fostering neighborly relationships, or encouraging the practice of relaxation techniques, can significantly reduce tension.

The whole thing kicks off when the property manager swaps the A/C for free, and suddenly the left neighbor treats the new unit like a personal enemy.
Noise pollution is a substantial environmental stressor that can negatively affect mental health in various ways. A study published in Environment International linked chronic noise exposure to increased anxiety and depression, highlighting the serious implications of living in noisy environments. This correlation is particularly relevant in a shared living space like a townhome, where the noise generated from one unit can easily permeate into adjacent units, affecting the well-being of multiple residents.
Furthermore, the impact of persistent noise on our mental state can lead to heightened stress levels and a diminished quality of life. Awareness of these effects can guide residents toward more considerate behaviors, such as keeping noise levels down during late hours or using soundproofing measures. By fostering a more mindful approach to noise, we can create a healthier and more harmonious living environment for everyone involved.

From a social perspective, the conflict theory provides valuable insight into the dynamics of this neighborly discord.

After the OP schedules the A/C tech visit and even has him check the neighbor’s place, the neighbor’s “vibrating the whole house” claim starts sounding suspicious.
And if you like dramatic turnarounds, these unforgettable Winter Olympics moments in photos are pure adrenaline.
Empathy plays a crucial role in resolving conflicts like these.

Territoriality is another psychological concept at play here, significantly influencing interpersonal interactions in shared living environments.

The OP agrees to pause using the A/C when asked, and it’s “fine, not great,” which makes the next complaint feel extra unfair.
Immediate steps should include reaching out to the neighbor to discuss their concerns openly and honestly, fostering a spirit of cooperation. This initial conversation can set the tone for a more harmonious living environment. In the short term, ideally within 1 to 2 weeks, it would be beneficial to explore soundproofing options for the A/C unit, as this can help mitigate the noise that is causing distress.
In the longer term, if direct communication does not yield satisfactory results, consider engaging with a mediator who can facilitate discussions and help both parties reach an agreeable solution. By taking these steps, you can work towards a more peaceful coexistence.

Then spring hits, the OP turns the A/C back on, and the neighbor goes right back to demanding more calls to the tech, like nothing ever happened.
This situation highlights the complex interplay of perception and communication in neighborly disputes. The discomfort caused by noise pollution can easily lead to misunderstandings, particularly when one party feels their living environment is being compromised. The Reddit user facing complaints about their A/C unit is not just dealing with a mechanical issue but rather with their neighbor's stress and territorial feelings. It is crucial for the tenant to recognize the neighbor's perspective and the potential anxiety that comes with noise disturbances. Engaging in a respectful dialogue could pave the way for a solution that addresses both parties’ concerns. However, the tenant must also prioritize their own comfort and well-being, finding a way to coexist that respects their needs while fostering a more harmonious living environment.
If the neighbor keeps moving the goalposts after the OP’s A/C was checked and the house was not even vibrating, they might be the real problem.
Before you judge the A/C neighbor, read how a renter refused her sister-in-law’s apartment request.
