When my husband and I built our home from the floor up, we consulted with a general contractor, plumber, electrician and HVAC professional. We wanted to make sure we got everything correct, and weren’t stuck making a silly mistake. Although the general contractor was very familiar with planning the layout of my abode, he had not specialized in doing electrical, plumbing, or HVAC systems work. I understand that everything from the location of power outlets to the thermostat, to the ductwork and drains will impact our life, budget, and comfort. I think I spent foremost of my time consulting with the HVAC professional. Determining what type of heating and cooling system works best for us was a significant challenge. We wanted a system that would provide year round temperature control without costing a ton in energy bills. We were hoping for a zoned system that would allow us to customize temperature options room by room. We eventually settled on a forced air furnace and central air conditioner which has a duct system concealed in the ceilings and crawl space. At this stage, I didn’t realize how intricate and important the plan of the duct system can be. To ensure maximum airflow and energy efficiency in the HVAC system, the ducts can’t have any sharp bends in them. The number and placement for the HVAC vents in the rooms is really important. It was helpful that the HVAC contractor was able to fabricate the metal ductwork, because he could accommodate our timetable and verify the products and materials. Now that the HVAC system is installed and up and running, we couldn’t be happier with the results.
