Essential DIY Tips for AC Maintenance and Repair


Keeping your air conditioning system in top shape is crucial for maintaining a comfortable indoor environment. While it’s always advisable to seek professional help from reliable HVAC experts like Thompson Plumbing, Heating & AC for major repairs and installations, there are several DIY tips that can help you extend the lifespan of your AC unit and ensure its efficient operation.

Air Filter Replacement

  1. Check your air filter monthly and replace it when it appears dirty or clogged.
  2. A dirty air filter can reduce airflow, causing your AC to work harder and consume more energy.
  3. Consult your owner’s manual or look for the filter size printed on the existing filter to ensure you get the right replacement.

Outdoor Unit Maintenance

  1. Keep the area around your outdoor AC unit clear of debris, leaves, and vegetation.
  2. Trim back any plants or shrubs that are too close to the unit, as they can obstruct airflow and reduce efficiency.
  3. Use a garden hose to gently wash away any dirt or debris accumulated on the fins and coils of the outdoor unit.

Thermostat Settings

  • Set your thermostat to a comfortable temperature and leave it there. Constantly adjusting the temperature can cause your AC to work harder and consume more energy.
  • Consider installing a programmable thermostat to automatically adjust the temperature when you’re away or sleeping.
  • In the summer months, set your thermostat a few degrees higher to reduce energy consumption.

Ductwork Inspection

  1. Check your ductwork for any visible signs of damage, leaks, or disconnections.
  2. Seal any gaps or cracks in the ductwork using mastic sealant or metal tape (avoid using duct tape, as it can dry out and fail over time).
  3. Insulate any exposed ductwork to prevent energy loss and improve efficiency.

Annual Professional Maintenance

While DIY maintenance can help extend the life of your AC system, it’s still essential to schedule annual professional maintenance with a reputable HVAC company like Thompson Plumbing, Heating & AC. Their technicians have the expertise and specialized tools to thoroughly inspect and service your system, ensuring optimal performance and identifying any potential issues before they become major problems.

By following these DIY tips and scheduling regular professional maintenance, you can keep your air conditioning system running smoothly and efficiently, providing a comfortable indoor environment for you and your family.
