"Outstanding work. Outstanding professionalism. Outstanding customer service. I can’t say enough about how easy it was to work with Joseph and his team. I highly recommend him for all HVAC needs. They knew exactly what was needed for my home HVAC. The unit works perfectly. Did not have to wait for equipment to be ordered or long to have it installed."

"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."

"We have been trying to get an AC unit for the longest especially with this heat and iâ m so thankful i came across socal air quality. The installation and the whole process went very smoothly thanks to Pedro. I received a very affordable pricing and would definitely recommend the quality + the customer service."

"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!"

"Ray was very responsive and professional since my first contact with him. He came out early the next day to diagnose my broken AC and walked me through the testing stages and explained what he was doing, how it works, and why. He tried several methods to get the system up and running but ultimately, we had to replace the old unit. Since we were in a 100 degree heatwave, Ray was mindful of our situation and came early the next day to install the new unit within an hour. Very fortunate to have a seasoned professional like Ray to help us amidst the heat and Covid. I would highly recommend him to anyone looking for central AC work."
