“I had a great experience with One Hour Heating & Air Conditioning in Torrance thanks to Joshua! He was professional, knowledgeable, and extremely courteous from start to finish. He arrived right on time, quickly diagnosed the issue with our AC unit, and explained everything clearly before beginning the repair. What really stood out was how respectful he was of our home—he wore shoe covers, cleaned up after the job, and made sure everything was running perfectly before leaving. Joshua truly went above and beyond, and I wouldn’t hesitate to recommend him to anyone needing HVAC service. Great service like this is hard to come by!”

“Installed their air purifier about 2 months ago. Very pleased with it. My allergies feel better I’ve only needed claritin a couple times. Noticeably less dust as well. Installation guy was prompt and thorough.”

“One Saturday morning my mothers wall heater wouldn't turn on, so we phoned One Hour Heating & Air Conditioning. Since it wasn't cold, an appointment was made for the following Monday. A couple of technicians arrived and checked out the heater. Turned out the 22 year old heater has a pilot light that had gone out. Yes, surely that unlike me, even the cat had it figured out. I digress. The techs explained the issue, relit the pilot and verified the issue was resolved. For any future issues, One Hour Heating & Air Conditioning of South Bay will be the people that I call.”

“I wish I could select 10 stars for this team I had an excellent experience with One Hour Heating and Air South Bay! My techs, Joshua and Jason, were incredibly professional and thorough throughout the entire process. From the very start, they took the time to answer all my questions and coordinated smoothly with my landlord to ensure everything went off without a hitch. Joshua provided an estimate and explained everything in detail, so I never felt out of the loop. The craftsmanship was top-notch, and I felt confident knowing they were handling the replacement of my wall furnace heater. They literally took care of everything-- remove the old unit, permits, install, thermostat, make sure it's functioning well, etc. It was a breeze I also had the pleasure of speaking with Raymond, the chief contractor, and Maryam, the owner, both of whom were incredibly responsive and helpful. They made sure everything was taken care of promptly, and I really appreciated their communication and transparency. Bottom line: you're in great hands with One Hour Heating and Air South Bay! They made what could have been a stressful experience straightforward and hassle-free. I give this incredible team my highest possible recommendation and hope others use them as well”
