The cost of the same day service and resolution was surprisingly, and thankfully, affordable... I would definitely recommend calling EZ Air Conditioning & Heating if the need arises. There's no one else I would call for AC help!

Came out on a Saturday when my AC went out. He was able to have it running in no time. He later came back to do maintenance on it & was very thorough. I highly recommend EZ Air Conditioning & Heating and their staff.

Special thanks to Jonathan, Chris, & the install team - we couldn’t be more happier. We wanted to work with a company that had a good reputation as well as an authorized Carrier dealer and we got exactly that.
- Edward F. -
The installation crew did a great job. They left the inside and outside area clean. Stayed until we knew how to use the new system. We recommend EZ Air Conditioning & Heating without hesitation!
