A solid HVAC preventive maintenance program shouldn’t be just an option—it should be a MUST. Think of it as preventive car maintenance, if you fail to routinely replace your car’s filters and belts or change its oil, the engine would fail to operate and your car won’t work. This also applies to your HVAC system.

Fortunately, you could extend your HVAC system’s life and even boost its efficiency by doing some simple maintenance tasks. Otherwise, you might need more extensive repairs or worse, an AC, heater, or furnace replacement. Experienced HVAC technicians in Utah adds that you must perform some of the following preventive maintenance tasks yearly, seasonally, or as soon as you can:

  • Always make certain that approximately 20% of registers are open to avoid putting unnecessary stress on your HVAC system.
  • Make sure to replace your HVAC’s filter every three months, but do check it every month. Change it if it’s already significantly clogged and dark, and you might need to change it every month if you have furry pets. Likewise, consider buying a new high-efficiency filter. This has a pleated design and electrostatic charge for attracting superfine particles.
  • Ensure that there’s always a clearance of at least two feet around your outdoor heat pump and/or air conditioning unit.
  • Every month, check if the insulation on refrigerant lines that lead to your home is damaged or missing. Repair or replace as needed.
  • During summer, turn off your furnace humidifier’s water supply. Come fall or at times when you expect you’ll need more heat, set your humidistat to a relative humidity of about 35% to 40%, replace the humidifier’s wick filter, and then turn on the humidifier’s water supply.
  • During fall, summer, and spring, remove twigs, pollen, leaves, and other kinds of debris that have accumulated on the sides and the top portion of your outdoor units.
  • Once a year, ward off clogs by pouring a mixture of water and bleach down the condensate drain of your air conditioner to prevent algae and mold buildup, which could cause clogs.
  • Once a year, ensure that your outdoor units are leveled and are firmly placed on the ground. Replace your carbon monoxide detector’s battery, too.

While you could do pretty much everything on this list, you should likewise consider getting professional HVAC technicians to inspect your HVAC system in the spring and fall, and perform maintenance tasks if needed. They could inspect and thoroughly clean your system’s mechanisms and wiring, which are tasks that an average homeowner won’t be able to do properly.

Make sure to follow these HVAC preventive maintenance tasks to save yourself from more costly repairs, avoid future issues, and prolong your HVAC system’s service life.
