Here are just a few unsolicited testimonials from our happy, comfortable clients.
Honest, cost conscious, service oriented
D&T first became our contracted heating and cooling contractor for maintenance on the aging system included with our condo purchase during 2016 Delaware Home Show. With the 2017 Home Show this weekend I feel compelled to write them a superior recommendation. This excellent company kept our heating and cooling together until we had the money to replace last October 2016. I had 5 company's study our condo and the heating & cooling challenges of the 30 y/o two story, flat roofed home. The second story was freezing in winter and a sauna in summer. Long story short of the 5 company's D&T came up with the most reasonable, cost conscious, satisfactory and logical plan to replace our heating/air system, add a second zone to the second floor and repair/seal the duct work to all areas. They have been extremely professional, efficient, accommodating and attentive to all the work, maintenance or new install throughout this past year long association. We are extremely happy with the out come of our new heating and cooling system installed. I can not recommend them higher than 5 stars here, but would definetly give them 10********** if I could!
Our technician Mark came out went to work called us down to the heater and went over our problem step by step he was very very thorough and explained our options . I would highly recommend d and t heating and cooling to anyone. We had horizon and I don't know how they stay in business very unprofessionaland wanted too much money.D and T heating and cooling has my business from now on and I will telly neighbors about them very professional. I give more than 5 stars if I could.
I have lost so much respect for most local companies because we always seem to be over charged or taken advantage of, but D&T was EXCELLENT. They were quick, affordable, clean, friendly, and had our heat back and running smoothly. I know our family will definitely call on them in the future.

I am so happy that I went with D & T Hearing and Cooling for my heat and a.c. replacement! All of guys were very professional and super polite! They completed the install in a timely manner, and were great about follow-up as well. They gave me peace of mind, and came to the rescue right before summertime (Great payment options as well)!

HVAC Service & Repair
My AC went out during the middle of summer. I called a couple of major chains but calls went to voicemail and I did not get a call back from them for at least 24 hours. One major chain never bothered to call back. I did a Google search for HVAC and D&T was in the list. I called, left a message. To my surprise, someone called me back within an hour. Impressed!! I had a technician come out to my home the very next day. My evaporator coil was leaking refrigerant and was completely frozen over. D&T has up front pricing. No hidden fees and/or charges. Impressed again!! They came back two days later and replaced my coil. And I have not had a problem since. I also sign up for their maintenance plan so I will always be covered. Doug Renshaw, his technicians and office staff are professional and courteous. I have been a loyal customer for over 3 years.

I am very happy with the services I just received from D&T Heating and cooling. My oil furnace had stopped working when it was 20 degrees outside. D&T came right out and repaired the problem before my home got below 60 degrees!! I was also very happy with the cost as well! The tech was very friendly and informative, as well as the office staff.
