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.

"Same good service over several years. Because Hartman's takes care of my furnace every year, there were no problems."

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"
