What our clients say

Absolutely awesome service!!! The technician actually cared about the customer. This is the 3rd company to come out and look. My parents have an older system and don’t have the cash to put into to it. They listened to what the issue diagnosed it and fixed it without trying to force a new system on them. The customer service was awesome !!!!


Wonderful service anytime I have had an M&M technician come out - I am a contract customer and had Andrew out for A/C cleaning and Jason for my furnace cleaning - All techs are fantastic and their service manager Jim is the BEST in the field !!!


M and M Heating and Cooling did something phenomenal for us. They replacied an attic fan that had gone three days out of warranty at no charge! Not only did they not charge us for the new fan but they also did not charge us for any labor for the replacement. I simply cannot tell you how grateful I am. I highly recommend this company. We’ve also used them successfully in the past for our furnace maintenance. They are my first call when we need a new furnace. Call them!
