I purchased the Impecca AC based on a recommendation from the NYT and my own research. I had previously bought a Whynter ARC-14SH, but found it to be loud and clunky, so I returned it.

The Impecca cools my 950 sqft place very well during the PNW summer. It is much quieter than the Whynter AC and the inverter compressor is also less noisy. The 5-piece window kit accommodates my large 60 sliding windows, which is a big plus.

Update:
The heating is working well, but make sure to set up the drain hose when turning on heat mode to avoid the P1 error. I set up the drain hose to drain into a bucket and haven't had the P1 error since. I need to empty the bucket once a day because a lot of water comes out.

We used to have a Costco portable AC in our room for years, but it never cooled the room during the day and was very noisy. However, we now have a new AC that works nonstop and keeps the room cold all day, which is amazing. It's also not noisy like the old one, and just sounds like a strong fan blowing. We can't believe the difference it has made.

The installation kit was not very practical as it warped from the sun and customer service was unhelpful in replacing or providing a warranty. I ended up using a piece of plywood which fit perfectly and made the machine much better. I may cut a hole for the ducting through a larger piece of plywood in the future as the plastic adapter seems fragile. The machine works well, but the remote has too many buttons and the machine's buttons are not intuitive. It gets loud when the AC kicks on but then becomes really quiet in 'standby' mode. I wish it would stay loud as I only use it while sleeping. Overall, it seems to be a good machine, but I have not read a positive review of the plastic installation kit and the lack of customer service support in replacing it is frustrating. However, I am glad I used plywood instead as it is much better.

This air conditioner is truly amazing! It is super quiet and the foam rubber inserts prevent any loud knocking noises. The power of the 12600 BTU model is incredible and it works well even in a humid environment. The app is easy to use and the unit does not have any issues with filling up with water. It is a bit pricey, but definitely worth the investment. I would highly recommend this air conditioner to anyone in need of one.

The room stays cool and comfortable with this unit. Even at 9 am, when it's 85 degrees outside, I never have to walk into a hot room. The lack of a timer to automatically turn on the unit is a drawback, but overall I am happy with it. The convenient remote control also adds to my satisfaction.

The unit is in good condition overall, with only a few scratches on the front that are purely cosmetic. The most important thing is that it works well, so I would give it four stars.

I purchased this portable A/C to replace a noisy one in my bedroom. This one is incredibly quiet, even when switching from fan to A/C mode. It doesn't have the harsh sound of other A/C units when the compressor powers up. It's true that it's 42 db on the low fan setting when the A/C isn't running. With the A/C running and the fan on low, it measures 46 db from 3 feet away. The remote allows for both auto off and auto on times, which is a handy feature.

I recently purchased two Impecca 12,600BTU units and encountered some mechanical issues with both of them on first use. However, after resolving these issues, I found the units to be phenomenal. I wouldn't consider buying any other brand as Impecca's units clearly outperform others I have tried.

The Impecca units have a unique fan structure and mounting, which has led to some vibration issues and potential self-destruction. However, when the units work, they work very well. The build quality is excellent, the form factor is great, and the instructions are clear. The Impecca app and integration with the device were seamless, and the install video was helpful.

The AC and heat modes work wonderfully and are very quiet. The heat mode does not require any reconfiguration and the included drain adapter for condensate drainage is very helpful. However, I did encounter issues with persistent rattling and high-pitched squeaking, which I was able to resolve.

In January 2023, my 8-month-old unit started periodically emitting a loud buzz and stopped working. Impecca Customer Service initially provided poor support, but eventually refunded me for the malfunctioning unit. While I am a little concerned about the disposal fee for the unit, I appreciate the customer service I received from Impecca.
