Thank you Cool Air!“

“Adario's did a solid, professional job replacing our broken down HVAC. After working hard for three days last week, including Saturday, they came on Sunday and finished up. Overall, they put in a great deal of work in a short period. It is so much more comfortable to be in our house now with the AC taking out the heat and humidity.“

“We just bought a house a few weeks ago and didn't realize our oil gauge was not working correctly until about 4 o'clock when we came home from work to no heat and a 55° house. We called Mac Lellan as brand new customers and they were at our house filling our tank by 4:25 on a Friday. It was so greatly appreciated!“
