"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Fantastic. Felipe gave a comprehensive quote, performed the work on time as per our agreement, worked during the day without a ton of bother to me (I work from home) and his team was professional and respectful. They cleaned up after themselves every day and it was very easy to live in my house while work was being done. The drywall is gorgeous and the work I"m very happy with. This job was a lot of random things - moving plumbing, reframing walls, completely redoing the drywall, installing a window, removing and replacing a walkway, etc."

"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!"
