Letters from our satisfied customers.


“I am a Realtor in the Chambersburg PA area. Reputation is extremely important to me personally and business wise. I was referred by a friend to D.A. Gsell Heating & Air Conditioning for a heat pump issue. Would not only recommend this company to future clients of mine, but would definitely pass their contact information on to my family members.”

Very professional. Definitely worth contacting. They pride themselves in superb work and top quality parts and components. I would highly recommend this company.

We purchased three Mitsubishi ductless heat pumps in November 2015 from D.A. Gsell Heating and Air Conditioning. We are very pleased with the results of both the heat and air conditioning heat pumps.  No more do we have to put those big air condition units in our windows. Damian was very helpful, conscientious and very knowledgeable about his product and strives to satisfy his customers.

We found everyone that worked with him to be very conscientious also. From start to finish everything went well.  The inside and outside work was finished very meticulous. There was no mess tracked throughout the house and they cleaned up as they finished their project. The work was done in the time frame promised and very efficiently. 

We would highly recommend D.A. Gsell Heating and Air Conditioning for your ductless heat and air conditioning needs.
