When you're in the market for a new HVAC system, look for one that has an electronically commutated motor (ECM) outfitted for variable speeds as part of the furnace or air conditioner. These motors offer significant advantages over permanent split capacitor (PSC) motors because they use less electricity, run more quietly and adapt their speeds to conditions in your home. Also known as a variable-speed blower motor, an ECM with a motor controller can operate at whatever speed is needed to meet the conditioning needs of your home and the specific airflow and filtering factors in your HVAC system. For example, if your air filter is dirty, a variable-speed ECM will ramp up its speed to compensate for the restricted airflow.

"The service was great as always. The 2 men who came to install my new furnace were very professional and took the time to explain what they were doing and showed me what the problem was with my old furnace. Thanks Mr Hartman for coming up North and for having a great crew."

"Came home from work to find that my furnace wasn't working. Since the temperatures were extremely mild for November, I just left a message for them to call me the next day. Received a call by 7:25 am and told that the repair man would be there in approximately a half hour. He was at my house by 8:30 and he had it back running within 45 minutes. He went the extra step and made sure that there was no other possible issues before he left. I'd recommend Hartman Brothers Heating to anyone, they are courteous, reliable, knowledgeable and won't gouge you like some companies."

"I signed up for a service plan, as I’m not much of a handyman myself. They had a variety of payment options with the service plan, so I was able to start monthly payments, which works best for me. Our service person was polite, and he explained everything in terms I had no problems understanding. I had an additional issue with an attic duct being chewed through. He got up there and got pictures right away so they could put together an estimate. Same visit, no hassle. And because of the service plan, there was no charge for the system check. I just let him in, showed him around, and he worked his magic. No regrets here. There’s a very good chance I’ll just keep up this service plan for the entire time I own my home."
