How Important is HVAC Preventative Maintenance?


Many people tend to wonder whether HVAC preventative maintenance is worth the time and money. Well  just like a motor vehicle needs regular tune-ups to operate at its best level of performance, so does a Air Conditioning and Heating system. While preventive maintenance benefits the system directly, having this service performed by trained professionals brings with it benefits to you as the home or business owner as well.


Optimal System Performance


Over months of use, a furnace, heat pump or air conditioning unit loses lubrication and develops buildup of dust, dirt and other debris. Preventive maintenance includes system lubrication and cleaning that restores proper functioning to the motors and fans, resulting in better performance. Cleaning or replacement of the system's air filter allows the heated or conditioned air to flow without impediment throughout the air ducts and vents. This means that the system will not have to work as hard to keep up with the temperature setting on the thermostat.

Conserving Energy


Vehicle maintenance often results in an improvement in mileage per gallon of gasoline, and HVAC preventative maintenance similarly results in a lower rate of energy use. As the motors operate more smoothly and the system does not have to cycle as many times to achieve and maintain the temperature set point, it does not consume as much fuel. Lower fuel consumption means lower utility bills, which benefits all home and business owners when it comes to paying those monthly upkeep costs.
