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."

Holtzople is a leading HVAC company in Frederick, Carroll, and Washington counties in Maryland, as well as Adams and small parts of Franklin & York counties in Pennsylvania, featuring all the top brands in the Heating and Cooling industry, such as Trane, Bryant, Lennox, Carrier, ClimateMaster, WaterFurnace, and more. We recently added an electrical department to our services, making us your one-stop shop for HVAC and electrical needs. Quality is Not Expensive, It's Priceless!

"Ok, some neighbors complaint how expensive Holtzople can be, but boy, you don’t get such quality and service elsewhere. We have had them for decades and this year needed a new unit because ours was so old, and this latest model was installed in three days, right before that June heat wave hit. And you get two free inspections following installation to see that it is working optimally with the most incredible work force ever—on time, competent, polite, caring and oh so concerned that you are a satisfied customer. For our money, they don’t come any better! And you’d be amazed at the nos. of people who agree with us!"
