Excellent company! My AC unit died on a Tuesday and Mersey had installed the new one by mid-day Wednesday (1 day)…during a heat wave. From the office personnel to the service personnel, professionalism was displayed at every interaction. I’m extremely happy with the service and the turnaround time. Everyone was friendly and easy to deal with as well.”

Great job again by Mersey Heating and Air Conditioning. Logan came by to perform our annual maintenance on our Lennox Air Conditioner. Polite, professional and thorough job on the maintenance. I always go to Mersey for my air conditioning and heating needs (including purchasing our Lennox air conditioner a few years ago) and it is always a great experience. Thank you Mersey!

What Homeowners Say About Us

Mersey Heating and Air Conditioning were amazing. Their team was very responsive to our situation when our furnace broke down over a weekend. Their emergency response was excellent. Rocky was a great ambassador for Mersey. This is the second time Rocky has been our technician. He is extremely professional and very personable. He is very good on the technical front and did a great job dealing with all our maintenance and repair issues.”
