Called about 3:00 pm and was advised all techs were busy and no guarantees they could get to me today. Too my suprise they called back within 30 minutes. They had a tech close by and on his way. Tech showed up, I explained my problem he diagnosed it replaced my part and finished up within 30 minutes. Tech was very professional and polite. Prices were very reasonable. Will definitely use them again in the future.

I contracted Mount Holly Heating and Air to remove an old Heat Pump package unit and install a new Trane Hybrid unit. These guys did a fantastic job. The fit and finish is perfect and they did the whole job in one day. They where also alot cheaper then the other guys I got a quote from. The unit runs just like I hoped it would. I highly recommend them for any HVAC work weather an install or repair. These guys really do a great job and are always courteous and answered all my questions.

The BEST experience I've ever had with an HVAC company. Their customer service, timing and honest pricing saved our lives this weekend as our AC broke the night before we were having a weekend of family and friends over for a baby shower. Thank you MHHAC!

Very pleased with the service from these guys. Leave it to the A/C to quit working during the hottest part of the summer. It was 90 degrees in my bedroom last night! Fortunately, they had a technician out to my house the same day I called them. The technician arrived on time and was very professional and had the problem figured out in a matter of minutes. The repair cost was very reasonable too. I would highly recommend this company to anyone in need of A/C repair!
