"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."

"I first used Patagonia HVAC when my home AC broke. Guillermo, the owner, responded promptly and provided a quote for the repair. He worked with me to find the best new system within my budget and completed the installation within days. He was incredibly professional, and my AC has been working wonderfully ever since! I later hired him when the AC went down at my grocery store, and Guillermo had it repaired the very same day we called. I couldn’t recommend Patagonia HVAC more highly!"
