"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."

"Ked was my "usual" service tech for many years. He was always friendly & kind...and didn't mind letting my big dog say hi. He was always professional and efficient. I liked having the piece of mind in knowing my HVAC needs are met & running well. I have used their maintenance plan for many years now, and haven't been disappointed. Well, Caleb didn't disappoint either. He loved my "big boy" and had a great sense of humor. He was very thorough in servicing my air conditioner. I feel I get my money's worth from my maintenance plan each year. I love when they say, "Everything looks good, no problems. See you in the Fall.""

"Our AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

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.
