"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

Beltway Air Conditioning & Heating , LLC, is a family owned and operated business located in Hanover. We offer everything you need to heat, cool, and improve your indoor air quality in every corner of your home. Our high quality work with a smile is what keeps our customers satisfied. We make sure that we pay close attention to the details and take pride in delivering professional results to you at competitive rates.

"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."

"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

Family-owned and operated, Presidential specializes in residential and light commercial service and installation throughout MD, VA & DC.

"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!"
