- SCSaralyn Cohen2 days ago5.0We have serviced twice now. Excellent customer support. Dependable and extremely responsive. Very pleased with our service they provide. Reasonably priced and easy to communicate we will use them for all of our HVAC projects.
- OTOlivia TeranAug 12, 20265.0Robert came out and within the hour had our HVAC system running again. He was able to point out our service needs within 10 minutes of arriving. Prompt, professional, We will surely reach out again if the opportunity presents itself. Thank you
- SGShelley GutierrezAug 10, 20265.0Robert was great! Not able to fix the Ac but knew exactly what the problem was. He also connected the safety shunt off which was never connected by my shady contractor 5 years ago. Robert recommended a plumber whom came out later in the day. Robert was spot on with his assessment and the air conditioner was running that evening
- KKKatrina Fix (katrinaelgrande)Aug 6, 20265.0Will be recommending Robert and his team to all my friends and neighbors who need HVAC services!! Our AC unit broke during a heat wave (because of course) and Robert came the next morning. He was very thorough and communicative, and when we needed a full-system replacement, his team delivered. The 2 installation techs who came and did the work were polite, friendly, and efficient. When our thermostat gave us trouble, Robert came back day-of and got us all sorted out. Now we have working AC and couldn't be happier!
- LNLaszlo NagyJul 30, 20261.0Our HVAC system is only four years old, but it suddenly stopped blowing cold air. I called One Hour Heating & Air Conditioning, and to their credit, they responded quickly. Steven and Robert came out to inspect the unit. They told us there was a cable issue, that the refrigerant level was very low, and that the system had a leak they couldn't repair. They added three pounds of refrigerant, but it made no difference. Their only recommendation was to replace the entire HVAC system for $13,000, which I declined. After charging us $450 for the service call and refrigerant, they left without resolving the problem. I immediately contacted an independent HVAC contractor, who diagnosed and fixed the issue within two hours. Overall, I was very disappointed with the service and the lack of effort to repair a relatively new system.
