What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
