For some folks, their knowledge of the HVAC system that cools and heats their home is limited to that little white box on the wall that shows temperatures. Yet, knowing some HVAC basics is a great advantage for a homeowner when it comes to handling routine maintenance, conserving energy, and troubleshooting mechanical issues when they arise.
Following is a simple explanation of the most common residential HVAC set-up, the central forced-air heating and cooling system. Typically, this involves a combination of combustion furnace for heating and split-system air conditioner for cooling, though some homes use a heat pump for both heating and cooling. "Split-system" refers to the fact that there's an indoor unit containing an evaporator coil and fan, and an outdoor unit containing a condensing coil, compressor and fan.
The process starts when a furnace blower — or A/C or heat pump air handler — draws household air into the appliance where it's heated or cooled. The fan then blows the now-conditioned air throughout the house via a network of supply ducts and registers. The air returns to the main equipment through return ductwork, where the process repeats itself. In homes with furnaces, the furnace blower typically serves as the blower for the A/C.
You can help this process by taking care of routine maintenance, such as inspecting and changing the air filter when it gets dirty. A clogged filter will impede airflow through the system, forcing the equipment to work harder and consume more energy.
You can also aid your HVAC system by weatherizing your home – sealing air leaks in its outer envelope and making sure insulation is sufficient.
Scheduling annual professional maintenance for each part of your HVAC system (heating and cooling) is also essential. A poorly maintained furnace, A/C or heat pump will struggle to heat or cool your home, waste energy, and eventually experience breakdowns. Consider signing a comprehensive maintenance agreement with your trusted local HVAC contractor.
