What is HVAC Maintenance Service?

A thorough HVAC inspection and service should be performed on your system on a regular basis. A complete service involves more than just opening a cover and replacing a filter. Electrical heating units generally require the least amount of service. Oil burning units require the most service and thorough cleanings. Natural Gas heaters fall into the middle of the spectrum for service requirements. High efficiency units produce a water vapor while running and the drainage needs to be checked and cleaned, preferably every year but at least every two years.

Why Is Maintenance So Important?

The purpose of preventative maintenance is to keep your HVAC system up and running all season long with no surprise breakdowns, while operating at top efficiency.

All portions of your system should be inspected and cleaned. The heat exchanger, coils, condensate pan, blower motor and housing are only a few parts of the overall HVAC system. Newer blower motors are sealed units that do not require the addition of oil but older motors should be inspected. The blower assembly should be cleaned every five years, more often if you home is prone to dust, or other build up. Gas heaters should be checked for efficiency and carbon monoxide at least every two years.

The air-conditioning unit should be check for any refrigerant leaks. If older style refrigerant is leaking it must be repaired. While newer refrigerant is more environmentally friendly than the old style, it is also expensive. You do not want to have the expensive of constantly recharging your system. Air conditioning coils should be cleaned every two years.

Your HVAC company may also be your first line of defense against mold or bacterial growth. While they are performing your regular service, they will also look for signs of potential indoor air pollution. In addition, while they may not provide a duct cleaning service, they can provide you with the proper information that you will need to have the work done. The ductwork in your home is a part of your HVAC system. Professional HVAC contractors will look at your ductwork to check for areas with visible leaks to improve the efficiency of your system.
