"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"He made an appointment with me for the following day to determine the problem with my air conditioning. He added the parts that I needed and got my a/c unit working again quickly, very grateful, knowing the heat that is coming. He even gave me a discount on top of quick, efficient work. I learned a lot more on how air conditioning works."

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

They arrived on time, worked efficiently, and had my system running perfectly again the same day. You can tell they truly care about their customers and take pride in their work. Fair pricing, great communication, and excellent service from start to finish. I highly recommend Servlegacy to anyone needing HVAC service or repairs!"
