“Our furnace stopped working all of a sudden, at 4 AM on a Saturday morning. I spent half the morning calling dozens of companies trying to find someone to come out same day and do a furnace repair. After calling about 11 different companies, I stumbled upon one hour heating and air conditioning and they told me they will come out as soon as they can and it’ll be the same day before 9 PM which was very relieving because everyone else was just like we don’t have any technicians available or call back Monday. I called around 11 AM and they told me that someone would be out before 9 PM, however, shortly within the next three hours they sent a beautiful man named Rick to my house and he was definitely an angel in disguise after fixing our furnace and helping us spend a little less than we’d imagine he then offered us $100 coupon which really was a blessing for us. I will definitely use this service again. Rick was so nice and professional. Everyone was amazing and I’d recommend them 100 times.”

“I had an excellent experience with this company. The technician, Reinaldo, arrived at my door just an hour after I called, which was impressive. He was incredibly knowledgeable and took the time to share valuable tips on how to properly maintain my HVAC system. It’s clear that this company is run with integrity—they’re honest, efficient, and not out to overcharge or take advantage of customers. I highly recommend them to anyone in need of reliable HVAC service!”
