"Aaron was great! I put in my project yesterday evening & he reached out right away. I spoke to him the morning of my project & he came out to my house as a second opinion, giving me a better price than a competitor; arriving with all the tools/parts he needed on hand. He was very thorough in checking that everything worked properly after installation & is adamant about returning if there are any issues (which we do not foresee). Highly recommend Aaron."

"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!"

"There was just miscommunication in the beginning. I called to confirm my appointment as the technician was now late. They didnâ t have me down for that day or any record of my call. I then had to wait for parts to be ordered after diagnosing the broken freezer. I didnâ t know if he was going to order it. He said to call the office and tell them to order it which seemed weird. Then I couldnâ t pull out the refrigerator to unplug it myself in order to let it sit for 24 hours defrosting once the parts were in.. I was told on the phone that I had a circuit to the fridge that I could turn off. He had never seen my outdated box. Finally had it repaired which was quick at that point. Knowledgeable technician though."
