I had their tech out in 2023. Great, fast service at a reasonable price. Started feeling hot today (expected high of 91). and saw the thermostat at 79 i(set at 75). I tried a coiuple things and then called them. Three days out. The gentleman was kind enough to walk me through some checks, and found the furnace breaker tripped (I had missed it when I reset the breaker for the AC - duh) The phone call was free!
Can't thank these guys enough!

The team was responsive to my initial request, an appointment was scheduled in a timely manner and they arrived when expected. The diagnosis was made, parts ordered and installed the following week. I’ve had issues with my AC unit for years and previous HVAC companies have failed to properly diagnose the issue. I’m pleased with the service and workmanship of Marky Marks and will be recommending them to anyone who needs HVAC services.
