"22 years ago Hartman's installed our furnace/AC. When the unit recently started having serious issues Hartman's tried to repair the unit, spending a few hours but the aging unit had given all it could and wouldn't stay fired after the flame sense was cleaned and the rest of the unit examined.
That tech, who's name I have unfortunately lost - possibly Jim, thoroughly explained everything during his inspection so I could relay the information to my husband.
After I discussed financing options with Hartman's for the replacement Rick Hartman cared for every detail and made the transition seamless. Our issue began on 3/10 and the replacement unit was installed on 3/14; a needed part was driven overnight to meet the installation date. Kevin and Jason from the install crew were very knowledgeable, professional and quickly fabricated a 3 in metal base for a perfect fit. This crew comes prepared! Josh set the unit air force specs 4 times until we found my personal preference. Roger Hartman came out during installation to give us our paperwork and check with the install crew. The installation was completed in 7 hrs and the crew never took a break! I would hire Hartman's any day for a red carpet customer service satisfaction experience with a company that has a great reputation, a friendly and professional crew with many years of accumulated experience, all the employees clearly work well together and have excellent knowledge and workmanship and work ethics. I highly recommend Hartman's, you won't be disappointed. They not only arrived on time but we're actually a little early!

"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."

"Every thing went well, even though he had bad news that the unit needed to be replaced due to the fact that the unit was 18 years old and the refrigerant used in the day was R22 that it cant be purchased because of government regulations, now we will see what the estimate will be. The technician seems to be knowledgeable and was very professional about his work."

Today's ductwork design principles correct thermal losses, pressure imbalances and other errors that waste energy. In the past, design and fabrication of ducts were done with the aim of minimizing costs. If you're looking to improve your home's efficiency and comfort, you should be aware of the principles of modern ductwork design below.
The average homeowner spends 20 to 30 percent more energy than necessary for cooling and heating bills due to leaky and inefficient ductwork. If you are constructing a new home or 
The 
The most advanced HVAC technology you can buy has little value when ductwork design is neglected. In the past, the layout of residential ducts was often based on a “one size fits all” philosophy. Cost-cutting, not performance and efficiency, was the priority in fabrication and installation.
Ductwork design best practices are necessary to achieve maximum energy efficiency, as well as to provide comfortable airflow with uniform temperatures throughout your home. Rather than relying on rule-of-thumb estimations, you'll want careful planning to design the best duct system for your new home or retrofit. Work closely with your
