Maintaining your air conditioning system is crucial for ensuring efficient operation and prolonged lifespan. While professional services from T. N. Bowes are highly recommended for major repairs and installations, there are several DIY tips you can implement to keep your HVAC system running smoothly.

Air Filter Replacement

  1. Check your air filter monthly and replace it every 1-3 months, or as needed.
  2. A clogged air filter restricts airflow, leading to higher energy consumption and potential system failure.
  3. Consult your system’s manual or contact T. N. Bowes for the correct filter size and type.

Outdoor Unit Cleaning

  1. Regularly remove any debris, such as leaves or twigs, from around the outdoor unit.
  2. Gently wash the condenser coils with a garden hose and a soft-bristle brush to remove dirt buildup.
  3. Ensure the area around the unit is clear of obstructions for proper airflow.

Thermostat Optimization

  • Set your thermostat to a comfortable temperature and avoid frequent adjustments.
  • Consider installing a programmable or smart thermostat to optimize energy usage.
  • Clean the thermostat’s cover and replace batteries if necessary.
