“Thank you so much for your prompt, excellent service on January 13th. You responded right away, diagnosed and fixed the problem with my renters lack of heat and even went above and beyond by cleaning the filter and noticing the bookshelf location blocking the return. You’ve got my “5 Stars” rating!! Many Thanks!”

Judy Fuller Sacramento, CA

“I had a heating problem with one of my rentals. I had another person come out and they recommended a complete new unit. I called A Five Star Heating and Cooling for a 2nd opinion. Five Star was able to fix the system the next day at a reasonable rate. They were quick and easy to work with ! I will be using them for all my heat and air needs in the future and would definitely recommend them!”

Christopher Wallace Davis, CA

“A Five Star Company is fast, professional and does a good job. I manage five apartment complexes, and I use A Five Star Company to service the AC and heater units. I’ve been using him for about a year now, and he responds quickly when I call him and is able to get to the complex in a timely manner. He does a good job at a very reasonable price.”

Scott Tygerson Sacramento, CA

“A Five Star Heating and Cooling replaced our heat pump at the end of the year. They where there the same day, the service was great and they did a great job on the new installation. William was very honest and explained how everything would flow throughout the installation. It was a great experience and I would highly recommend A Five Star Company to anyone.”

Fred Wright Roseville, CA


“Our AC unit stopped working on the weekend. I called several local service companies on Monday morning and all were booked solid for a week. When I called “A 5 Star Heating and Air” Mark answered and said he was in the area on another job and said he would call right back after he completed that job. Mark called back within 2 hrs and arrived at our house 15 minutes later. In less than an hour he had our A/C working again and even gave us a great deal on the service.”

Kate Robinson Carmichael, CA

General Manager of Ken's Creekside Sedona, AZ

“I agree with all the positive reviews here. These guys are great! Called them in the morning to fix our AC and heater,about an hour later they come over and fix it at a great price. Very honest also – shows you exactly what’s wrong and what needs to be replaced. I highly recommend these guys!”
