"Our air conditioning went out today. My husband called Hartman Brothers. They were here within 30 minutes. I can’t remember the guy’s name but he was very nice and did a great job! Hopefully we won’t have any more problems but if we do, we’ll call Hartman’s."

"Josh was very knowledgeable! He was able to find the problem with our furnace and fix it. He was not pushy and didn't try to sell us anything we didn't need! We will definitely do business with Hartman's again when needed!"

"I've had Hartman's install new Bryant H/Vac systems in 2 houses now and I've been pleased with the outcome at both houses. They are local, on time and reasonably priced. I've had a couple minor problems and Hartman Bros treated me fairly and took care of the issues. You don't buy 2 complete H/Vac systems from someone you don't trust or has treated you unfairly."

"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."

The return air ducts are a key component of your HVAC system's air distribution network, but it's easy to overlook their importance since they don't send out heated or cooled air. 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.
