“Jordan was the sales rep we worked with and he was very professional, friendly and helped us making our decision on our ac and furnace unit. He provided great service and was available for questions anytime with quick responses. We had Blaine and Johnny install our ac and furnace units. They were very courteous and professional. They did an excellent job on the install and left my house clean as promised. Overall I am satisfied with service from M&K and would recommend them.

“We needed a new AC/Heating system installed and had a great experience with M&K as we have had in the past. John, the salesperson, came by and was very helpful in determining our needs and selecting a product. Only a few days later we had Blaine, Randy, and Jonny came by and were very professional in their installation. They put down runners, were very respectful, and ensured that everything was code compliant, tidy, and taken away before they left. Thanks M&K!

“Our furnace and A/C died in the middle of a huge heatwave. Service response was fast and once they determined it couldn’t be fixed, we were able to select a new unit same day and it was installed in less than a week. Other companies we called couldn’t get a service tech out at all so we appreciated the fast response.


When homeowners book installation services with M&K Heating and Air Conditioning, they can expect a high-quality installation performed by professional technicians from start to finish.

  • The state of your home’s ductwork
  • The accessibility of the area you want to install your new air conditioning unit
  • The techniques required to install your new unit

Proper air conditioning installation is key to ensuring your home is easy to cool without using more energy than required.
