Service was great. Technician, Justin, was communicative and resolved our issue very quickly. He also gave us tips on getting better filters. Honest and down to earth, and military discount was a nice plus. Would definitely recommend this company! Services: HVAC system repair, A/C system maintenance

Tony Bryant installed a furnace, AC unit and thermostat in my home. Not only did they arrive on time, but they where extremely professional through the entire installation. They walked me through the process and kept me informed through the day. There was no hassle on my end.

Daniel did fabulous job to check our aged AC system in every detail, he notified us the gas leak from both furnaces which could be the reason causing my headache for a long period. It is essential to have your AC checked regularly to avoid any potential damage and you can trust Daniel for sure. Service: A/C system maintenance

Everything from start to finish was so easy, seamless, high quality, and professional. Everyone from the company was very courteous and easy to communicate with. Thanks to the whole team I now have heating & air in my condo! Highly recommend.

Just got a new heat pump (ac/heat), all new duct work, and insulation. Start to finish great experience from Steven (who designed/quoted) and team. The guys who showed up to do the work were timely, professional and all around nice dudes. My bulldog (who's a maniac) needs a bit of attention and having people in the house was quite stressful. Tony, Bryant, and Chris all made sure to give him a little pat'n'scratch each time they walked past him which made the whole thing much less traumatizing for him and helped put him at ease with all the commotion going on. They did great work, cleaned up and complete a huge job in 2.5 days. As long as this unit does well, I give my experience 5 stars! Great work guys!

Erick was great, on time, called 30 then 15 min prior to arrival. Introduced himself to me, did a thorough inspection of the furnace and a/c system, diagnosed problem and gave me a few different options to fix the problem. I would recommend to friends and family

Andrew was by far the most informative contractor I've ever worked with. He really took the time to explain everything clearly and diagnosed the issue with our furnace which had been giving us issues for about a year. I will definitely continue working with Andrew and this company for all our heating and AC needs! Thanks so much!

Although it took several weeks to get heater working (ordered parts, then finding out it was the wrong part) once the correct parts came in the job was completed quickly by the technician (Bryant Hernandez). But each time technicians came they were always courteous and concerned. They even supplied two portable heaters to help keep my mother (95yrs old) and myself warm through the cold weather. When parts came the dispatcher even worked to have technicians come as soon as possible. Excellent customer service!

I only have wonderful things to say about this company and my technician. Andrew Rice was very knowledgeable about my system and thermostat. He went way above the call in teaching me about my system and telling me what was wrong with it. He worked very efficiently and was extremely kind. Give this dude a raise! You don't meet many people like him! The price was also VERY reasonable. I own several properties throughout San Diego and will never use another company for HVAC. Thanks again, Andrew!
