Highly recommend! Technicians did a great job patiently and explaining everything. Their installation crew is professional, courteous, and thorough. they did a superb job, even went beyond to make sure everything was right

They did a great job replacing our ductwork and getting our air going. In the middle of their busiest season, . Easy to work with, and quick to reply to messages.

They have great customer service , the booking process was smooth and Alex was great at what he was doing . Perfect company for your Air duct cleaning !

We had a central air system that wasn't working so well, we had no idea what was wrong, apparently there was a lot of build up and these guys gave a whole run down diagnostics and was able to fix it. It was very affordable and very fast!

Beware Beware Beware this is a rip off off company. The technician tried to rep me off. he wanted to charge $ 600 for an a/c system recharge with 4 pound of Freon. he quoted me a price of $ 125 per pound of Freon, he said they have a minimum Freon amount...

Great Company to work with. and I would absolutely recommend to any homeowner or business.

Our AC was giving us some problems and we checked on Google. We found out Guaranteed Quality Heating and Air through Google search and call them. The person who answered the phone was James and he gave us various options we had. Next day, Steve came...

Great company with sincere employees. Thank you Tony and Jannette.

Horrible customer service! Unreliable, didn't call when they couldn't come..... Not reliable at all!!
