Mel-O-Air Heating and Air Conditioning is awesome. Stacy the office manager is so helpful all along the process. The installers arrived on time and did a fantastic job installing our new HVAC system.

Emelia Z.

The Mel-O-Air team were flexible and responsive to my unique needs and time constraints. They did everything possible to install quality products at a great price. Scheduling was a breeze.

Nick K.

Just had the Mel-O-Air team replace my 18 year old Carrier Furnace and air conditioner with a new Carrier system. Price was the best out of three different quotes for the same system!

Karl L.

Probably one of the best HVAC companies around. I needed a new furnace installed over the winter and they were able to get it done in a timely fashion.
