"As always, Hartman Bros does service RIGHT! They are prompt, courteous, professional, clean and fairly priced for all services we've ever had completed. We were introduced to them in 1998 when we first used their services and have been faithfully returning for every Heating and Air need, including the building of 2 new homes. They are stellar performers providing excellence at a time when mediocrity has been touted as the norm in our society. They go well above and beyond in all they do."

"I absolutely loved the service we received from Hartman Brothers. They gave us an appointment right away, and the technician knew what our issue was based on my husband's conversation with the scheduler. As a result, he came prepared to fix our problem. The technician was also very nice and courteous. I would recommend everyone to give them a call for all your HVAC needs. Thanks Hartman for a job well done!"

"They worked me in early. Inspected and found the problem quickly. Explain the issues thoroughly and did not attempt to see me parts and services I did not need. They got the heat going temporarily and hope to have needed parts in a couple days."

"Brian showed me what was wrong with my air conditioning unit and explained everything so I could understand. He spoke to Vicki at the office regarding a needed part that would have to be ordered. They could have slapped a generic part on, but it would have only been a short-term fix. Instead of taking the easy way out, they are getting the part made for my unit so it will stay fixed, and they are coming back to finish the job as soon as they have the part. Hartman Brothers is ethical, knowledgeable, friendly, and they do the job right! I highly recommend them!"

To help you understand the vital role they play in maintaining your comfort and keeping the HVAC system working properly, let's take a closer look at what the return ducts actually do.
The benefit of a central air system is that it allows your entire home's temperature to be controlled from a single thermostat, with a single HVAC installation. But it also comes with a serious drawback: the ducts that deliver air to your living areas can develop leaks or tears that bleed off conditioned air before you can make use of it. When your ducts pass through crawl spaces and other passages outside of your living areas, this can lead to 
Indiana homeowners depend on their HVAC systems to stay warm and comfortable through the heating months. Considering that home heating accounts for 45 to 55 percent of the typical energy budget, there is also financial incentive to maintain a well-operating HVAC system with a seasonal inspection.
