Inefficient Cooling: When Your Unit Can’t Beat the Heat

Your air conditioner should keep you cool, but sometimes it struggles. This can happen for several reasons. Here’s what you should check:

  • Clean the air filter: A dirty air filter blocks airflow. Take out the filter and use a vacuum cleaner to remove dust.
  • Check for ice on coils: Ice can form on evaporator coils. Turn off your AC and let the ice melt.
  • Look at the thermostat settings: Ensure it’s set to “cool” and the temperature is lower than room temp.
  • Inspect refrigerant levels: Low refrigerant means less cooling. You might need a pro to fill it up.
  • Examine ductwork for leaks: Holes in ducts mean lost cool air. Use tape to close small gaps.
  • Clear plants from outdoor units: Plants can block your condenser unit outside. Cut them back for clear airflow.
  • Keep vents open: Closed vents make it hard for cool air to get into rooms.
  • Uncover all indoor vents: Furniture or curtains covering vents stop cold air from getting out.

Water Leaks: Indoor Drips and Outdoor Puddles

 

  • Find the source: Check where the water is coming from. It might be a clogged drain or a problem with the condensate pump.
  • Inspect the filters: Dirty air filters can block airflow, causing ice to form and then melt into water leaks.
  • Clean the drain line: Algae and mould can clog it, leading to backup and overflow. Clear it out to prevent puddles.
  • Ensure proper insulation: If pipes aren’t insulated well, they can sweat and drip water, much like a cold glass on a hot day.
  • Check refrigerant levels: Low levels can cause coils to freeze and then leak when they defrost. A professional should handle this fix.
  • Verify installation quality: Poor installation might be at fault. Make sure your unit has been installed correctly.

Condenser Challenges: Overcoming Obstacles with the Heart of the AC
