“Excellent contractor from initial phone call to installation. Very happy with services. Knowledgeable friendly people, which includes receptionist, owners and service technicians. Wonderful company.”

-Leonard of Hampstead

“They come, they fix, and they leave without charging you a fortune--and they don’t know it, but they also secured peace in the neighborhood and may have even saved your marriage.”
- Baltimore City Paper

“You guys were fantastic!”
- Hal B., Millers Island

“Joel was simply the most professional, no-nonsense technician we have ever had do work on our home. Neatly dressed, quiet, efficient, and a superb mechanic. We hardly knew he was here. Until the heat started working again, of course.”
- Mr and Mrs. Ronald T., Glen Arm

“While on vacation our house-sitter called to ask what they should do about the A/C unit that had failed. We said, “Call Farnen & Dermer”. They did and the air conditioning was up and running by the end of that same day for much, much less than we expected!”
- Harry and Ellen S., Owings Mills

“I have dealt with lots of contractors and repair techs. Farnen and Dermer is by far the best. I will definitely recommend them to others. They were Trane professionals. I am very happy with the performance of the unit. I am sorry that my builder 15 years ago used another brand. I have a second zone that I will, in time, use Trane and Farnen and Dermer for, again.”
-Joel G., Owings Mills

“Farnen & Dermer were excellent. I thought the in-home consultation was great. He explained to me what I needed and

did not try to sell me any additional services. Especially since I might move in the near future.  The team that came to install the unit was hard-working and very responsive to my questions.  They explained to me how to program the humidifier and the thermostat. They were also prompt, courteous and left my house very clean.  I would definitely recommend Farnen & Dermer to my friends and family.”

-Karl M., Catonsville

“I was impressed with the contractor’s presentation and knowledge of the products.  The contractor delivered everything he    

promised and more.”

-Nicholas C., Reisterstown
