I had a great experience with Dooley's heat and air. Tony was able to replace my old gas heater promptly, efficiently and at a good price. Everyone was very nice, friendly and courteous. Can't ask for more than that from an HVAC company. I will definitely use them again.

Dooley’s Heating and Air is definitely the place to call when needing help! My AC just went out and with this weather already hot, I contacted them immediately. Super friendly, prompt, and helped me get the unit back on without breaking the bank! Highly recommend!!

Sloppy work. Yes, the furnace got installed and it works. But they broke the wood base of the furnace shelf. Then to wire it up they punched holes in the wall through to another room, leaving wires exposed. Really unprofessional to do this and also to not mention it. Wouldn't recommend.

My mom's AC has been giving her issues and she asked me to post on a community site requesting assistance from someone who can work with her and give a free or cheap estimate. She is retired and on a fixed income and has been told before that it has a leak. Dooley's Heating and Air was recommended over and over so she asked that I call for her and see what they can do. They immediately set up an appointment and they came out right away. Tony found the issue, worked with my mom, and got it fixed super fast. Everyone was really helpful. We're so thankful, and would recommend them if you have any heating and air issues!

Dooley’s Heating and Air is the only company we have ever trusted with our AC units and hot water heaters, and they continue to exceed our expectations every time. Their team consistently goes above and beyond—especially in emergency situations when you really need someone reliable and responsive. We absolutely love our mini split unit that was installed in our ADU—it has been a game changer for comfort and efficiency. They also installed and maintain our HVAC system in our main home as well as our hot water heater, and everything has been running perfectly. It’s rare to find a company that is this dependable, honest, and high-quality. We highly recommend Dooley’s Heating and Air to anyone looking for top-tier service and peace of mind. ~The Anderson Family
