Bought a new condenser. Fair price. Were able to come out the day following my call. Only feedback I'd have is to communicate if they were to run late or what time to expect them for installation. Getting a call that they're there only because we discussed a specific day but not a time may not work out if someone's employer isn't flexible. I'd call them for service next year.

Half of the heat in my house went out during 40 degree temperatures this week and when I called, they were so nice and able to get someone out that same day. Initially the service man thought we'd need to replace the boiler, which was not what I wanted to hear, but whatever, it's cold outside and I just wanted heat! When Matt and Vince came to replace the boiler, they noticed my hesitancy and offered to have their supervisor review the system one more time just to get another opinion. Rich, the supervisor, said I could go either way, but it actually was repairable and they could fix it up where I could get another 3 to 5 years out of the boiler.
He could not have been more patient explaining everything and gave me great guidance. Everyone I have spoken and met with from there has been so incredibly lovely and helpful, it made what initially felt like a really stressful experience, much, much easier. I plan on using them for all my heating and cooling needs from now on, I can't thank them enough.

These good folks offer fantastic HVAC service. I used them on 3 separate occasions: A new furnace installation, new central AC replacement, and finally a new mini split solution to fully address comfort for the upstairs section of my home. These pros never disappoint! They provide honest and competitive quotes, show up on time, and are diligent with every aspect of their work effort. Don't hesitate to give them a try. You'll come back here and thank me later!

I am improving my last review since the owner called to apologize for not fixing the problem over the weekend that I requested assistance. He has retrained his staff to provide the kind of service that folks expect from a family-owned business like Assured Air. My review is specific to one bad experience, but overall they are dependable and trustworthy. Assured Air will treat you fairly.

Assured Aire came out 2 weeks ago to fix our whole house humidifier. They were prompt, professional and fixed the wiring on the humidifier. Very pleased and would certainly use them again. Don't forget to always tip your service technicians!
