10 Steps to Prolong Your HVAC’s Life

  1. Invest in a high-efficiency pleated filter with an electrostatic charge to capture even the smallest particles, including bacteria.
  2. Replace the filter every 90 days, checking it monthly for any signs of dirt or clogging. Monthly changes may be necessary for pet owners.
  3. Ensure a minimum clearance of two feet around outdoor air-conditioning units and heat pumps for proper ventilation.
  4. Weekly removal of debris (leaves, pollen, twigs) from the top and sides of outdoor units prevents blockages. Avoid discharging grass clippings onto the unit while mowing the lawn.
  5. Monthly inspection of insulation on refrigerant lines leading into the house. Replace damaged or missing lines promptly.
  6. Check the level of outdoor units annually to ensure they are on stable ground or pads.
  7. Annually, pour a mixture of bleach and water down the air-conditioner condensate drain to prevent mold and algae buildup, averting potential clogs.
  8. In summer, shut off the water supply to the furnace humidifier. In fall, replace the humidifier wick filter, set the humidistat to 35-40% relative humidity, and turn on the water supply.
  9. Avoid closing more than 20% of a home’s registers to prevent unnecessary strain on the HVAC system.
  10. Replace the carbon monoxide detector battery annually to ensure continued safety.

By adhering to this comprehensive maintenance plan, homeowners can actively contribute to the efficiency and durability of their HVAC systems. In conclusion, investing in a high-efficiency heating system tailored to your home’s needs not only ensures warmth but also contributes to long-term energy and cost savings.
