4 HVAC Parts Every Homeowner Should Be Aware Of

4 HVAC Parts Every Homeowner Should Be Aware OfWhile HVAC parts are individual components, they’re also integral elements engineered to function together in a system that generates reliable, efficient cooling and heating. A shortfall or defect in a single part may affect operation and performance of the whole system. While a working knowledge of the complete HVAC parts inventory definitely isn’t necessary for the average homeowner, here are four major components to be aware of:

Air Conditioner Compressor

Located in the outside half of the system, the compressor incorporates a powerful high-voltage motor and compresses refrigerant flow to efficiently disperse heat. Compressors are typically designed to last the life of the system. Due to the high cost, replacing a damaged or defective compressor may not be financially viable in an older unit. Upgrading to a new air conditioner may be the better option.

Furnace Heat Exchanger

The heat exchanger component separates the furnace burner combustion chamber from the system airflow. In addition to transferring heat to warm the airflow, the heat exchanger prevents dangerous combustion byproducts including carbon monoxide from infiltrating into the airflow. For safety reasons, a furnace with a cracked or corroded heat exchanger must be shut down until the unit is properly repaired or replaced.

A/C Coils

An air conditioner is primarily a heat-mover. Household heat is absorbed by refrigerant circulating through the evaporator coil located in the indoor air handler. Warm refrigerant then flows to the outside unit where it is compressed and absorbed heat is dispersed into outdoor air by the condenser coil. For maximum heat transfer efficiency, both A/C coils should be kept clean with regular annual preventive maintenance by a qualified HVAC service technician.

Ductwork

The network of ducts distributes cooling and heating throughout the house. Most if it is installed out of sight inside walls or up in the attic. Leakage in residential ductwork is common and may severely reduce system performance and efficiency. With an inspection and leakage test, your HVAC contractor can quantify the extent of leakage and suggest sealing options.
