You should service your air conditioner at least once a year, preferably in the spring before heavy use begins. Regular maintenance helps maintain efficiency, prevents major issues, and extends the life of your unit.

Signs that your air conditioner may need repair include:

  • Warm air: If it’s blowing warm air instead of cool.
  • Weak airflow: Reduced air circulation from the vents.
  • Strange noises: Unusual sounds like grinding, squealing, or banging.
  • Bad odors: Musty or foul smells coming from the unit.
  • Frequent cycling: If it turns on and off more often than usual.
  • High humidity: Increased indoor humidity despite running the AC.
  • Leaks: Water or refrigerant leaking around the unit.

To improve your air conditioner’s efficiency, you can:

  • Clean or replace filters regularly: Dirty filters block airflow and reduce efficiency.
  • Seal windows and doors: Prevent cool air from escaping by closing gaps and insulating.
  • Use a programmable thermostat: Set temperatures higher when you’re away and lower when you’re home.
  • Keep vents clear: Ensure vents and registers are unobstructed for optimal airflow.
  • Schedule annual maintenance: Regular servicing helps maintain peak performance.
  • Keep outdoor unit clean: Remove debris and ensure the area around the unit is clear for proper airflow.

The size of the air conditioner you need depends on the square footage of your home and the climate you live in. A general guideline is:

  • 1 ton of cooling capacity for every 600 to 1,000 square feet of living space.

However, factors like ceiling height, insulation, and sun exposure also affect the sizing. It’s best to have a professional perform a load calculation to determine the exact size needed for efficient cooling.

Your air conditioner may freeze up due to several common issues:

  • Dirty air filters: Blocked airflow restricts circulation, causing coils to freeze.
  • Low refrigerant levels: Insufficient refrigerant can lead to a drop in pressure, causing the evaporator coils to freeze.
  • Faulty thermostat: A malfunctioning thermostat may cause the unit to overwork, leading to freezing.
  • Blocked or closed vents: Restricted airflow can cause freezing.
  • Fan problems: If the fan isn’t circulating air properly, it can lead to freezing.

Addressing these issues promptly can prevent damage and restore proper function.
