Jaiden was our technician and I was impressed with his attention to detail. After the tasks were completed, I received detailed information and documentation via email. This was the cherry on top making the experience well above expectations. Bravo Zulu

Jayden is prompt , punctual and honest . I got quotes from 3 different HVAC professionals for my AC issue, everyone else either misdiagnosed or pretended that more work was needed than actually required. Jayden was able to root cause exact issue and fix it with oem part in under 2 hours same day whereas 2 other companies who looked at AC quoted 5 day turnaround time for the part and 6 hour job , on a functioning part that did not need replacement. Will definitely recommend Jayden and McCullough heating and cooling to all for any HVAC issues .
