In my search I've come across a lot of articles like the above advising to build an enclosure around it and add soundproofing material to the sides of the enclosure. I built a mini enclosure for my pool pump and used those rubber-like snap together tiles on the inside. They're the kind of tile you'd see on a gym floor. The sound is definitely less intrusive with the enclosure around it because the noise has nothing to bounce off of. 153 posts, read 242,837 times Originally Posted by Lauriedeee Lauriedeee, unfortunately this is a bad idea on many levels. The AC condensers require air flow and by blocking them off you will decrease performance and possibly shorten their life not to mention make repairing and replacement more difficult.

Additionally the OP is complaining of noise inside the house... what you suggest here will make matters worse. Because putting an enclosure around the units will create an echo off the panels. Based on the picture shown from the link you posted. There's a reason why manufacturer's make quieter units... Because they know people who don't like the noise will buy them. These tend to be more premium units with more comfort bells and whistles. Anything other than treating the root problem will give less desirous results. I didn't get in this business to offer solutions that won't work and make my job harder the next time. Oh but you said if I spent some money on a compressor blanket that my units would be QUIET. Trigger a car alarm in the back ground... are your units still noisy now? I've been doing this for 20 years. If you want the truth I will tell you. You probably won't like it, but at least you'll have the truth. I should add here that a compressor blanket will help, but everyone's definition of quiet is different.

If you go the compressor blanket route realize it's not perfect.

Comfort 13 Central Air Conditioner System - 24ABB3 | Carrier - Home Comfort This is most likely your unit model. (It has a scroll compressor) Noise level for this unit is rated as low as 72 decibels...not really as bad as I initially thought because upper end models are typically in the 65 decibel range. So there's really not that much difference here. To give you an idea how much noise this is... a vacuum cleaner is rated for 70 decibels / garbage disposal 80 decibels. Is this the kind of noise you are hearing? The other side of this is performance issues... are both of the units cooling properly? Reason I ask is if the valves are bad in the compressor it will still run, but they typically make a lot more noise when this happens.

Usually in these instances you will only get about a 10 degree drop across the coil. So it will still cool, just not very good and because of that it will run a lot longer, in extreme heat it will never reach temperature just run and run. The jokes go something like this...price to install ac unit My compressor is on a fitness kick, he just runs and runs and runs.why would my ac unit freeze up Or to the dispatcher after getting the call: I'm too tired to chase a compressor down the block... because he keeps running from me.air conditioning unit not heating 27,318 posts, read 24,258,848 times Google those words and you'll find plenty of sites that sell them.

All air conditioners, to some degree, are designed to minimize the sound they make. However, many home owners find the noise levels objectionable and greater than anticipated, after the installation is complete. The location of a condensing unit can significantly influence the perceived noise level. When you double the distance between you and the air conditioner, you decrease the sound by 5 dB, which is about ¼ as loud. While manufacturers do guarantee the sound levels of their equipment they can't guarantee the perceived noise level from patios, windows and bedrooms. Brinmar Sound Blankets are a popular solution for reducing compressor noise, from air conditioners or heat pumps. They are guaranteed to reduce noise levels to meet or exceed local noise laws and are compatible with all residential compressors. Brinmar Sound Blankets reduce compressor noise by 5 dB or more - a substantial 40% + reduction. The sound blanket fits inside the cabinet and wraps around the compressor - the noisiest component of an air conditioner or heat pump.

Brinmar's universal design accommodates hundreds of different styles and shapes of compressors. The two-piece design allows quick installation in tight cabinets where space is a consideration and where the compressor is close to the coil or the fan. The sound blanket is securely attached with hook and loop closures, which are durable and make installation quick and efficient.

See all 95 customer reviews (newest first) This was easy to install and really did a good job of cutting down the noise of the compressor. The compressor used to start with a startling bang, and was noisy while it ran. This cover has really made a difference in the sound of our air conditioner. Before installing this compressor blanket it was possible to hear our AC compressor from across the street. Good product.......although I thought that the decibels would be lower.
