Get Your Air Conditioner Ready for Summer in 6 Simple Steps

When the temperature rises, don’t be caught simmering in the hot summer heat! The last thing you want on the first really hot day of summer is to find your central air conditioner doesn’t work. But, this can be the case if you don’t do a bit of quick annual maintenance before summer arrives. Spring is the perfect time in Central Illinois to get your air conditioner ready for summer.
A central air conditioner utilizes an indoor air handler and an outdoor compressor. The condenser unit is typically located outdoors. This is the portion of your air conditioning unit that you’ll want to clean and maintain. Your air conditioner has been sitting idle during the cold winter months collecting leaves and other debris. Replacing the filters, cleaning the condenser, and performing a few minor checks will get your AC unit into shape so it’s ready to operate and cool your home efficiently this summer.

Here’s how to get your air conditioner ready for summer in 6 simple steps

1. Safety First
Turn off the circuit breaker before working on your air conditioning system. Be sure to turn off the power to the condenser at the service panel before working on your air conditioner unit. The condenser also typically has a 240-volt weatherproof disconnect box located near the unit. This contains a lever, fuses, or a circuit breaker to shut off the condenser. Be sure to turn this off as well.

2. Clean or Replace the Filters
Clean or replace your furnace or air-handler filters whenever they begin to looked clogged with dust. Or, at least twice a year. Not changing these filters will restrict air flow and reduce the efficiency of your air conditioning unit. Dust filters also recirculate dust into your home. For information on how to do this, see How to Replace Furnace & AC Filters.

3. Clean the Air Conditioner’s Condenser Coils
Clean your air conditioning unit’s condenser coils and fan of debris. A central air conditioner’s condenser unit, typically located outdoors. It is a large fan in a metal box with sides that look like grilles. If your condenser unit was covered during the winter, uncover it. In this case, there’s likely not much debris to clear away. If it wasn’t covered, you’ll likely need to clear away a larger accumulation of leaves, yard debris and dirt. Make sure the fan is free and clear of all debris. Next, check inside the box. Air moves across radiator-style condenser coils. Check to see if debris has clogged the coils. If so, these coils need to be cleaned so your condenser unit works at it’s highest efficiency.

To clean the coils:
• Remove the side and top panels or protective grilles from the condenser unit. Note: Double check to make certain the power to the condenser unit is turned off.
• Lift off the top. The fan may be attached to it making it heavy. Note: Don’t tug any of the wires connected to the fan.
• Using a refrigerator coil brush or a soft brush on a vacuum, gently clean the coils from the outside of the unit. After you clean the outside, vacuum coils from the inside. Note: Be careful not to bend the delicate fins or damage the coils.

4. Clean and Clear Debris
Clear all leaves and debris out of the base of the condenser. If your air conditioning unit has a drain, make sure the drain is clear. Clean the blower’s fan blades using a vacuum or a rag. Clean up any excess water inside the unit. Once everything is cleared and cleaned, reassemble the condenser.

5. Check the Coolant Lines
Refrigerant tubes or pipes run from your air conditioner’s evaporator on the air handler to the condenser outside. These lines are usually covered with a foam coolant line insulation. Check to see if there are areas where the insulation is frayed or missing. If so, replace it with new foam insulation sleeves, or wrap the lines in a spiral fashion with foam insulation tape.

6. Test the Unit
Test your newly cleaned air conditioning unit after allowing the unit to dry thoroughly. You’ll need to turn the power back on to your condenser unit.

Turn the power to the condenser back on by doing the following:
• Turn the thermostat in your home to off.
• Turn on the power at both the disconnect box and at the main panel.
• Switch the thermostat to cool.

Please note: The air handler or furnace blower blows the resulting chilled and dehumidified air through ductwork to the home’s rooms. Repairs to your central air conditioner’s sealed refrigeration system is not a do-it-yourself job. They should be handled by a professional HVAC service pro. You can, however, do certain cleaning and maintenance tasks yourself to ensure efficient operation and keep the need for professional service people to a minimum. Some of those tasks are detailed below.
