Key Takeaways

  • Clean or replace your AC filters frequently to cut energy costs and improve air quality.
  • Check the condensate drain regularly to prevent water damage and keep efficiency high.
  • Clean both indoor and outdoor AC units often to avoid airflow blockages.
  • Check your home’s insulation, especially around pipes, for better temperature control and lower bills.
  • Get a professional to do yearly maintenance checks on your air conditioner for long-term savings and fewer breakdowns.

Inspect and Replace Your Air Filters

Keeping your air conditioning system running smoothly involves regular checks on the air filters. Dirty or clogged air filters can lead to a host of issues, including reduced efficiency and poor indoor air quality.

  • Switch off your HVAC unit before starting any maintenance work. This ensures your safety and prevents damage to the system.
  • Locate the service panel on your unit. It is usually found along the length of the indoor unit or behind the front grille of a room air conditioner.
  • Open or slide out the panel to access the filter. Some models may require unscrewing or unclipping to open.
  • Examine the air filter for dirt and debris. Brush down and If it’s washable, you can clean it with water.
  • Allow the filter to dry completely. Putting back a wet filter could cause issues such as mildew growth in your system.
  • For disposable filters, simply place a new one into the slot. Make sure it fits correctly and that there are no gaps around the edges.
  • Close up the service panel securely after replacing or cleaning your filter.

Regularly Clean the Condensate Drain

After ensuring your air filters are in good shape, focus on the condensate drain next. A blocked condensate drain can cause water damage and lower system efficiency.

During a maintenance visit we test the indoor drain by pouring water into the drip tray to ensure it is free flowing and clear of debris.

When the unit is operating in cooling mode, you will often see the drain dripping outside.

Maintain Cleanliness of Indoor and Outdoor Units

Keeping your indoor and outdoor air conditioning units clean is vital for their performance. Dirt and debris can block airflow and reduce efficiency.

  • Clean the indoor unit’s evaporator coil with a soft brush to remove dust. This coil absorbs heat from your home, so it needs to be clear.
  • Wipe down the exterior of the indoor unit with a damp cloth to keep it free of dust.
  • Check the outdoor condenser coils have good airflow and remove any leaves, grass clippings or other debris. These coils release heat from inside your home.
  • Keep plants, shrubs, and other garden elements at least 60 cm away from the outdoor unit for unblocked airflow.
  • Hose off bugs, dirt, and grime from the outdoor unit’s side panels regularly, especially after storms or high winds.

Check and Improve Insulation

Good insulation keeps your home warm in the winter and cool in the summer. Check walls, floors, and attic spaces for proper insulation that meets recommended standards. Upgrade or repair any areas where you find gaps or damage to save energy.

Sealing leaks around doors & windows can stop air from escaping. This helps your air conditioning system work more efficiently.

Adding insulation to your loft is a smart move. It traps cool air inside during hot months and warm air during cold times. Look at pipes too, especially those leading from your heat exchanger outside.

Schedule Regular Maintenance Checks

Regular maintenance checks by a professional technician are essential to keep your air conditioning running efficiently and prevent potential problems. Hiring a professional for regular maintenance can help identify and address any issues before they become major problems, saving you time and money in the long run. Having regular maintenance will also keep any manufacturer’s warranty valid. Understanding Common Air Conditioning Problems


Keeping your air conditioning in top shape is simple and smart. Replace or clean filters to breathe cleaner air and help your system run smoothly. Make sure the condensate drain is clear, so water doesn’t leak out.

Keep both indoor and outdoor units free from dirt to ensure good airflow. Regularly check insulation around pipes for better energy use and protection. Remember, setting up yearly checks with a pro can save you trouble later on.

These easy steps will keep you cool, save money, and give you peace of mind all summer long!

FAQs: Does Air Conditioning Use Gas?
