You and your family deserve to receive the best care and the best service. Not every heating & A/C company gives you the quality people and care that Presidential does. We offer 40 Years of Award-Winning Quality People, Quality Installation, and Quality Service. Delivering this quality service and care for your home is our commitment to you! Family-owned and operated, Presidential specializes in residential and light commercial service and installation throughout MD, VA & DC. Ask us about our system replacement specials and The Advantage Maintenance Plan for preferred VIP service. Presidential has been awarded the Carrier Factory Authorized Dealer Award and is a member of the ACCA (Air Conditioning Contractors of America) and the Quality One service network.

"Excellent service! I had a 26yr old A/C and Propane furnace that I wanted to update to an ALL ELECTRIC high efficiency heat pump. The price in the estimate was much higher than I was expecting, but they worked with me and brought it down considerably, provided I could accept an install slot in a couple of days due to a cancellation. Go for it, I thought! Unfortunately, it turned out that the estimator/salesman (who shall remain nameless) apparently got a bit confused and set up the equipment as a hybrid propane system - not the all-electric system that I wanted. Ugh. I only realized this when the installers had the indoor unit in place, and I saw the propane burners. Doh! So, I explained the situation to them, and they pulled the unwanted unit out and jumped through the hoops to order the correct unit and its accessories (wiring, breakers etc.), with no change to the price. They were very friendly and polite through all of this even though it meant the wasted work and that they had to come back the next day with the new IDU. Anyway, the final install all went well, and they were very friendly and respectful of the property and explained all the install details as they went (sorry Melvin, for all the pestering!) I'm very happy with the company and the installer's knowledge and professionalism. RECOMMENDED!"

"BELTWAY AIR COMFORT SERVICE is a terrible company. Horrible customer service. Incompetent technicians. They came to my home when my AC broke and 13 days later still no update. I called and texted repeatedly and got no response from the company. It's been two weeks in the sweltering heat we still have no AC. First they said they had to order a part, then I they found out they hadn't put the order in for the part. The dispatch was rude and claimed he didn't know who the owner was when I asked to speak to him. I found out these are the same ripoff artists that misdiagnosed my mom's HVAC resulting in her buying an entire new unit for over $10,000, and then the unit kept shutting off because the real problem was a regulator for the gas line. They're incompetent and unprofessional."

Heating and Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Assessing location for airflow, convenience, and minimal noise impact.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.
