Heat ducts in a house are usually installed in the floor or the ceiling. But which one is preferable? Both locations have positives and negatives, depending on a number of variables. Note: No matter where you place the ducts, fundamental facts of duct design always apply: The size of ductwork must be properly calculated to accommodate the required airflow volume and duct spans should be routed with as few sharp bends as possible.

"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers."

"I have called Hartman Bros twice for problems with my home air conditioning. Both times I felt that the pricing was fair. I appreciate that they seem to start with trying to repair and not jump to replace."

"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."

"Mario was a friendly, polite technician. He answered my questions to my satisfaction. In my opinion, he fits the profile of all technicians from Hartman’s who we have dealt with— friendly but always professional."

"I had an excellent experience with Hartman Brothers from start to finish. After dealing with an incomplete and frustrating repair from Peterman Brothers, Hartman Brothers was a breath of fresh air. Their technician spent several hours thoroughly troubleshooting my tankless water heater, walking through the issues clearly and professionally. There was no upselling, no pressure, and no shortcuts—just honest, methodical work. Based on their findings, I chose to upgrade to a new tankless water heater, and the decision was entirely mine. At no point did they try to push a sale or steer me toward anything unnecessary. The installation was clean, the communication was excellent, and the entire process felt transparent and trustworthy. It’s clear why they have such a strong reputation in the Fort Wayne area. Their professionalism, responsiveness, and genuine customer‑first approach really stand out. I’m very happy with the new system and with the service I received. "
