There are many factors that determine the lifespan of an HVAC system. Manufacturing, correct sizing and quality installation are very important factors, and the usage and local weather play a part in system wear and efficiency, too. The one essential factor you have the most control over for extending HVAC lifespan is how well your cooling and heating systems are maintained. Use these tips:
Quick Cycling
Frequent starts and stops aren’t good for efficiency, comfort or HVAC components. The thermostat heat anticipator is supposed to prevent quick cycling, but can actually cause it if its setting is wrong. To adjust this device, remove the thermostat cover and look for a metal pointed lever. Move it a notch or two until the HVAC system stops quick cycling.
Furnace Filter
Don’t underestimate the importance of the furnace filter. A dirty evaporator coil isn’t going to do a good job of cooling your home. The blower motor may come to a grinding halt if a clogged filter isn’t changed. Check your furnace filter each month in periods of high HVAC usage.
Ductwork
Poor duct design, such as leaky ducts, closed dampers and uninsulated ducts in unconditioned spaces, make your HVAC system work harder and longer. Have your ducts inspected in the spring and fall to ensure they’re helping HVAC performance rather than hampering.
Condenser and Compressor
The HVAC cabinet located outside your home contains the condenser and compressor. If the condenser is dirty, it can’t do its job of releasing heat energy efficiently. If the compressor is caked with dirt and grime, it can overheat and your A/C or heat pump will shut down. Clean the condenser and compressor cabinet with a garden hose.
Professional Preventive Maintenance
Professional preventive maintenance each spring and fall is essential for maximizing system lifespan, efficiency and home comfort. Moreover, preventive maintenance pays for itself in lower energy bills and fewer repairs. Ask your HVAC technician about contract service agreements.
