This article provides practical tips to help you achieve “Quality You Can Feel, From A Company You Can Trust.”

Changing Air Filters

  1. Locate the air filter(s) in your HVAC system, typically located in the return air duct or the blower compartment.
  2. Check the manufacturer’s recommendations for the recommended filter type and size.
  3. Replace the filter every 1-3 months or as needed, depending on usage and air quality conditions.
  4. Ensure proper airflow by installing the new filter correctly, following the directional arrows.

Cleaning Outdoor Condenser Unit

  1. Turn off the power to the outdoor unit at the circuit breaker or disconnect switch.
  2. Remove any debris, such as leaves, twigs, or dirt, from the unit’s exterior and surrounding area.
  3. Use a soft-bristle brush or a garden hose with a low-pressure nozzle to gently remove dirt and dust buildup from the condenser coils.
  4. Straighten any bent fins on the coils using a fin comb or a specialized tool.

Inspecting Ductwork

  1. Visually inspect exposed ductwork for any signs of damage, leaks, or disconnections.
  2. Use a damp cloth or a vacuum cleaner with a brush attachment to remove dust and debris from accessible ducts.
  3. Seal any visible gaps or holes in the ductwork using foil tape or mastic sealant to prevent air leaks.
  4. Consider scheduling professional duct cleaning every 3-5 years for optimal indoor air quality.

Thermostat Maintenance

  • Clean the thermostat and its surrounding area with a soft, dry cloth to remove dust and debris.
  • Ensure the thermostat is level and properly mounted on the wall.
  • Replace the batteries in the thermostat annually or as needed.
  • Consider upgrading to a programmable or smart thermostat for improved energy efficiency and convenience.
