Heating & Air Conditioning / HVAC near Merrimac

“David Heating & Cooling was great! As a new homeowner they were very helpful and answered all of our questions. During our maintenance check they found a few issues with the system and were able to fix them on site! One piece they needed to order and came back the next day to repair. Very pleased and will always be using in the future!“

“They are AMAZING! I’ve been using them for the past 7 years. They do great quality work that you immediately notice. Their professionalism is also second to none. Highly recommended.“

“I had 2 water valves replaced for both of my washing machines .The service men were very professional when they arrived.

They were on time & accessed what had to be done.
When they realized it was a double set of washing machines, they were upfront with me & said they only brought one valve .

After going to get a second one , they changed them out in just a short time .
They explained everything that they were doing in regards to testing the lines & the installation of the valves .
I was surprised that they even vacuumed the area they were working in before they left .

They were very knowledgeable, efficient & did a great job .

I would highly recommend them !!“

“They worked with me during this hot 4th of July 2026. AC stopped unexpectedly. Just need a capacitor replaced.The girls in the office are amazing! professional and very helpful, and very friendly! I won't use anyone else. They replaced my AC unit 6 years ago. I received a quote from another BIG shop for 3x what Kearney charged. They (Crny) wanted to replace my entire system heating/cooling system which was not necessary. Kearney was honest and 6 years later 100% correct & honest. No hard sell. Just honest, clean, reasonable group! Very grateful for your help!“

“Had a great experience with Mike D yesterday. He went above and beyond our expectations to help improve our AC functioning. We had very layman way of explaining our issue and he was thorough in looking through our whole system and finding the issues. Climbing into our attic (100 degrees+) he noticed several pinched flex pipes and iterated on moving them and checking the flow temp to ensure it was improving. This was something we had been struggling with for 6 years. Great addition to the team! Give him a raise!“

“We’ve had Jim out several times. He is consistently competent, professional and timely.“
