Your air system should be felt not heard. You should breathe with confidence while experiencing a constant temperature from room to room. It should run efficiently but not cost you an arm and leg and it should be 2K21 tech approved.

I was looking for a HVAC contractor in Orange to redo my A/C system and upgrade the old ductwork. Found The Attic Doctor on Yelp. They installed a brand new Trane condenser and furnace. Their lead HVAC technician was a pro. It was also a huge plus that they are also licensed insulation contractor who can replace my attic insulation. Very happy to hire The this small local company to get all the work done right at once!

We just relocated to Orange County and our new house needed a lot work done. We needed an insulation contractor as well as a HVAC contractor to do the insulation work and change the A/C system. The Attic Doctors was the only company that could handle all the services we required. It was awesome that we didnt have to shop around for various home upgrade services. They are the best!

My sister had them fix their furnace and add a new filtration system, so I thought since my sis is real picky, to say it mildly, I need to ask them to check out my old, never touched AC unit. Hey, I was beyond impressed with the technician. He just did whatever he needed to do and corrected a few issues and it didn’t cost me an arm and a leg!
