Home Heating & Cooling
Heating & Cooling Overview


You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. And yet we all neglect and take for granted the thousands of hours our Furnace and Air Conditioner runs yearly. Regular preventative maintenance is the best way to promote trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most.

MD Contracting provides priority service for their customers who have an annual maintenance or service agreement. Your relationship with MD Contracting will be worth its weight in gold when it's a 95-degree July day and your air conditioning system has stopped working. Plus our MD Maintenance Gold Program comes with free diagnostic and service calls with no extra labor charges for nights and weekends.



Bi-Annual, Preventative Maintenance (PM) will ensure that your system runs as efficiently as possible. Your MD Contracting Services, HVAC/R Specialist will:

  • Do a complete system operation check in both cooling and heating modes
  • Check all other major components and safety devices

Clean both indoor and outdoor air conditioner coils
