“Matt with McCarthy's did a fantastic job.I normally do not leave reviews but Matt was wonderful to work with. He was on time, professional, and friendly. He let me know what was wrong and was able to do the repair around our busy schedilule. He made some recommendations but didn't try to pressure me into anything extra. I really appreciate the level of service we receive everytime McCarthy's comes to do yearly maintenance too. I highly recommend their services.”

“Lwu did a very good job & very detailed. Only complaint is when I spoke to Mckenzie to schedule appt. She said there are possibly some coupons on their website for my service & I did find one. When I presented this to Lwu he said they do not honor those anymore only a gift card. You might want everyone on the same page when it comes to this issue. Thank you Lwu for your great service!!”

“5 Stars – Outstanding Service and Professionalism! I contacted McCarthy’s One Hour Heating & Air Conditioning on a Sunday evening regarding a potential HVAC duct leak in my ceiling. To my surprise, they were able to schedule a technician to come out the very next day. I received an email confirmation for the appointment and even a professional biography of the technician, Jack, which was a great touch. On the day of the appointment, the office gave me a courtesy call letting me know Jack would arrive within 30 minutes—excellent communication throughout the entire process. When Jack arrived, I explained the issue, and he conducted a thorough inspection of the HVAC system, including the condenser and coils, and performed a diagnostic check on the cooling system—all of which were within proper limits. After his assessment, Jack determined the cause of the leak was likely due to closed vents in the basement and other areas of the home, along with a dirty filter and the system working overtime during several extremely hot and humid days. His explanation was clear, professional, and easy to understand. I asked about preventative maintenance options, and Jack explained their plans, including a great offer for military members. I ended up signing up for their $11.11/month 11/11 maintenance plan, which I really appreciated as a veteran. Overall, I couldn’t be more pleased with the fast response, professionalism, and honesty from McCarthy’s. I highly recommend them for anyone needing HVAC service or looking to set up a maintenance plan!”

“This service was great. The technician fixed the problem just to make sure it would be a fix instead of giving me a "maybe this $200 fix will be to trick or maybe the whole thing is bad" I appreciated the assurance and the evidence that the technician gave and I felt no pressure. It was exactly what we needed and nothing more.”
