"Compass Heating and Air Conditioning installed a new Daikin air conditioning unit when my current one failed. They gave me a fair quote to repair the one that I had. I decided to replace it due to the age of the unit I had. I felt that Mike reviewed all of the options with me. His estimate for a review was much better than the one the I had gotten from another company. He seemed much more knowledgeable and explained everything to me so that I had a clear understanding before I decided. Dave, Mike and Tyler worked hard to get the new unit installed - the same day! They found problems with my existing ducts and did repairs so that the system was safe. I like that they showed me the problem. They explained the ductwork repair. They did a thorough job of cleaning up too. I could not be happier. I strongly recommend them for any heating or air conditioning needs. I will certainly use them in the future for routine maintenance as well as any repairs. Thank you for your quick response, high quality work, professionalism!"

We are a family owned and operated plumbing and sewer company.

"Paul did install an AC for me that worked fine though a contractor later told me the equipment he installed was low quality. But I hired him to do an install for a condo and the unit he installed seized up immediately. He told me it would be a 3 day invasive fix to get a new working unit. I hired another contractor who installed a high quality AC in three hours that has been working fine. He did not respond to my request to honor the warranty or refund any of the money paid for a job that he had no expertise to perform obviously as his work failed immediately."

Heating and Air Conditioning questions, answered by experts

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.
