I waited on phone line (1-800-CARRIER) for 22 minutes. Then gave up and pressed “1” for call back. About 40 minutes later a young woman returned call. I explained that my local dealer told me that Carrier did not support Ecobee thermostats and I wanted to verify that information. She asked to put me brief hold. After a few minutes she returned to line and advised that I would need to contact Ecobee and she provided phone number. I asked if there was someone at Carrier I could speak with. She said no because they have “no technical support staff” in customer service.

I decided on a Carrier split system for heating and cooling in an older ranch with electric baseboard heat only. Best decision ever!! It's efficient and cheaper to operate than the new Ruud gas system in my old condo. The heat is so warm. It's not anything like the old heat pumps that seemed to throw cool air for heat. My old condo and my house are about the same size. Both are on slabs. My heating/cooling bills at the house are half of the condo's. What a blessing. Thank you Carrier!!

We purchased ours give or take 8 years ago. It was best deal in our price range and for size wise in comparison to the square footage of our home. I would definitely recommend them to anyone looking to purchase or replace their existing one.

I installed the condenser and A-coil myself since I am licensed to do this and the unit works great. I wish I would of done it right after purchasing the house instead of waiting 4 months. The summer was extremely hot and in a 65-year-old house with leaky windows and doors, my electric bill was never over $275. I was actually expecting higher. Since then I have had a new furnace put in and love it, keeps the downstairs and upstairs plenty warm without breaking the wallet on the gas bill. 4 ton 15seer condenser, 5 ton A-coil with TXV, adn 125,000 btu 95% furnace.

My HVAC system from Carrier has worked well from the start and has never skipped a beat. It is the best system I’ve ever owned. And the price was affordable as well. And guess what - I work for Trane!
