"We reached out to Hartman Brothers as our previous place was actually rude and acted like didnt care as we had an issue with the AC. Our systems at that point were about 14 years old. We got a quote from previous place and i about fell off my chair. Called Hartman Brothers and asked if they could provide a quote for us on both and in AC alone. Super impressed as Rick came out next morning. Looked at what we currently had and that same day had a complete quote to us. We were scheduled for May 26 install however they had a cancellation and came out May 17. Both techs were super amazing. Talked with us with everything and answered all of our questions. They came out a little before 8am and everything was installed and working by 2pm. Cleaned up their stuff ( which was great as we have 3 dogs). Never have we experienced this type of professionalism from any company. We are all so pleased with Hartman Brothers including Vicki in the office. She was great helping me and explaining the maintenance agreement. If you ever need a great team you wont be disappointed with Hartman Brothers ! We thank you all for helping us and doing a great job. It was also great we kept it local as well. Glad to be a part of the Hartman Brothers family now ! Thank you again."

"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."

"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."

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.

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
