Maksym and Dmitriy were very helpful when my mini split gave out. They came out for free to give an estimate and were able to install a new one within a couple of days. It was done in a few hours and works great. Highly recommended.

Recently, our AC unit completely ran out of Freon, so we called True North Heating & Air for help. They were quick to respond, and their technician discovered a leak, which he expertly repaired. After fixing the problem, he professionally refilled the system. Watching them work, it was clear they knew exactly what they were doing. Thanks to True North for their professional and efficient service—highly recommended for any HVAC issues!

Our AC in our apartment was blowing hot air instead of cold—haha! We had met Dmitriy from True North Heating and Air before, so we gave them a call. They came out and quickly figured everything out. The filter was clogged and another part needed replacing, but they handled it both efficiently and affordably. We’re so glad we chose them. Highly recommended for anyone in Irvine, Orange County!

Our AC wouldn’t turn on at all, so we chose True North Heating & Air because they were the closest HVAC service to us great park Irvine. Their technician arrived the same day we called and replaced the capacitor (if I’m not mistaken), even though our AC isn’t that old. They also performed maintenance. The team was both friendly and professional. If you need anything with your HVAC, give them a shout—highly recommended!
