"Great service. Took the time to explain what was going on with my furnace, and didn’t make me feel stupid. Was genuinely concerned about my wellbeing, strongly encouraging me to get carbon monoxide detectors—which I’m having installed right now. I will definitely use this company again."

"Great guy and good service had me fixed up went out of his way to get ac going."

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"Very well. The technician/repairman, Benji, was knowledgeable, pleasant and respectful. We have not had people in our home due to COVID, but he was careful to use a mask and keep appropriate social distance while assessing and later fixing our problem. He knew immediately that our problem was the motor and instead of saying right away that we needed a new machine, he said that he thought that a replacement motor was the way to go. We agreed. He had to order the new motor and the company called to fix a followup appointment about 10 days later. Since we were doing the repair with their company, we did not have to pay for the original service call. Benji came back and did the replacement very efficiently and we are in business again for a total of US $ 269. A very good deal compared to buying a new machine. Thanks to All American Appliance Service, Benji and also Cindy who responded to my initial call. We are very satisfied with their services and would call on them again."
