Check Your Thermostat and Wiring

Sometimes, the thermostat may not be calibrated correctly, or the wiring could be faulty, preventing your AC from cooling properly. Ensure your thermostat is set to ‘cool’ and try lowering the temperature a few degrees below the current room temperature. If you suspect wiring issues, it’s best to seek professional help to avoid further complications.

Replace Dirty Air Filters

A clogged or dirty air filter can restrict airflow, causing your AC to work harder to cool your home. Inspect your air filter monthly and replace it at least once every three months, or more frequently if you have pets or allergies. Proper maintenance can improve airflow and efficiency.

Inspect for Refrigerant Leaks

If your evaporator coils are frozen or if you notice ice buildup on your unit, it could indicate a refrigerant leak. Refrigerant is essential for heat exchange, and a lack of it can hinder your AC’s cooling ability. Contact an HVAC professional if you suspect a refrigerant leak for safe and effective repairs.

Clean Your Outdoor Unit Regularly

Dirt and debris can accumulate on your outdoor AC unit, blocking airflow and reducing efficiency. Keep the area around your outdoor unit clean and clear of obstructions. You can also clean the condenser fins and wash the condenser with soap and water to maintain optimal performance.

Consider Your AC Unit’s Age

If your air conditioner is more than 15 years old, it may be time to consider an upgrade. Older units are less efficient and may struggle to cool your home effectively. Investing in a new, energy-efficient model can improve cooling performance and lower your energy bills.
