"It only took a few hours and the service was professional and well done. The serviceman was highly competent and friendly. Since I had purchased the 1956 house less then a year earlier, I had questions about how the automatic sprinkling system worked which he explained to me very well.
I plan on using this company for more repairs and upgrades on this home. I would totally hire them for plumbing and HVAC work, and will!

"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."
