“I can’t say enough great things about McCarthy 1 Hour Heating and Air and especially their technician, BioZa! From the moment he arrived, BioZa impressed us with his incredible knowledge and professionalism. He was not only super informative but also worked incredibly fast — our issue was completely fixed within just 15 minutes of him being here. What truly sets BioZa apart is how he took the time to explain everything clearly, giving us valuable advice on what to watch for in the future and helping us understand when it might be time to consider a new air conditioner. It’s rare to find someone who is both highly skilled and genuinely cares about educating the customer. If you want quick, reliable, and expert service with a technician who goes above and beyond, look no further than McCarthy 1 Hour Heating and Air. BioZa’s work deserves an A++ rating — absolutely outstanding! Thank you so much for making this process easy and stress-free. We’ll definitely be calling you again!”

“Booked the appointment for service to AC. Was supposed to be after 6 pm. Technician Richard put on a new capacitor. Was there and done before 6 pm and the house is already cooling down nicely! Highly recommend!”

“Absolutely incredible service! McCarthy’s One Hour Heating and Air arrived at my home within one hour of booking, which was a lifesaver since my house was over 100 degrees and I have pets. I was so impressed by how punctual and professional they were. From the friendly customer service to the technician wearing booties to keep everything clean, every detail showed how much they care. I also love that they’re veteran owned. Truly beyond 5 stars—THANK YOU for taking such great care of us!”

“Sam came out to inspect my long overdue furnace and AC. Very professional and filled up my refrigerant for maximum cooling. He cleaned up my AC very nicely. Our long haired dogs thank him.”

“Our A/C stopped working. The tech Sam arrived when they said he would and he quickly diagnosed the problem. Courteous and knowledgeable. We needed a new system. The salesman Carter came out the next day and presented our options. Professional and detailed. The whole process was about as painless as a $18K decision could be. Their financing options make it all affordable. Highly recommend McCarthy's One Hour Heating & Air.”
