If you have a properly sized air conditioner, its cooling capacity will be approximately the same as your home's cooling needs on the hottest summer days. An air conditioner's rated cooling capacity assumes it's operating under good conditions. These are typically provided as long as a quality installation job was done and adequate maintenance is performed. If your air conditioner isn't providing adequate cooling, follow these tips on how to make your air conditioner colder:
- Clean the evaporator and condenser coils. Dust and dirt on the evaporator coil makes it less effective at absorbing heat from your home's air, so it won't get it as cold. On the condenser coil, dirt and debris makes it harder for the refrigerant to shed the heat it gained into the outdoor air. The evaporator coil might only need to be cleaned once a year, but the condenser coils are exposed to the elements and may need to be cleaned as frequently as twice a month.
- Replace your air filter regularly. Air filters protect your air conditioner from airborne debris and also help improve your home's air quality. When they get too dirty they have a high resistance to airflow and reduce the airflow rates. Since less air is moving past the evaporator coils, this means less cooling gets provided.
- Don't turn the thermostat all the way down in an attempt to cool your home faster. The main way air conditioners maintain your home at the desired temperature is by turning on and off, so lowering the temperature won't actually make it cool your home any faster—it just means you'll have to remember to turn the thermostat back up to make the air conditioner turn off when a comfortable temperature is reached, instead of the air conditioner turning off automatically. Also, it could cause the unit to break by freezing up.
