Best heating and air conditioning pros near Walnut Creek, CA

"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"Prompt, courteous, hard working! Called for service and they came the same day and gave me an estimate for repair and an estimate for a new furnace! I decided on a new furnace as mine was 18 years old! They came the next morning and were done within 2 hours! The thing I liked most was they didnâ t pressure me at all but waited patiently for my decision!"

"Perfect Star sent a technician out to assess my HVAC issue. and it turned out to be my ducts had been torn apart by critters getting into my crawl space and trying to nest. I got a crawl space cleanup crew to address that problem but Martin (my HVAC technician) told me about an air purifier that could be installed to my HVAC units. He installed those for me right away and they are working great."

"Alanis Air did a great job with my HVAC project. John Alanis answered all my questions and worked with me in deciding which system I should choose when replacing my very old system. His crew completed the work in one day, cleaned up the area and disposed of my old system. They were very efficient, knowledgeable and friendly. I would recommend Alanis Air for any of your HVAC needs! Thank you John, Santiago, Angel and Ismael :-)"

"I had my A/C capacitor go out on me during the peak of a heatwave. I got on all the apps to find a hvac company that could come out asap to fix it. 411 heating and AC called me back immediately after reaching out and setup an appointment for the next morning. He showed up on time, was very professional and had great tips for me on how to do some preventative maintenance on my unit to extend its lifespan. I would recommend them and use them again!"

They install two HVAC units at my home and also provided awesome after sales service. I would recommend them highly to other. Thanks"
