Air Conditioner Maintenance

Annual Air Conditioner Maintenance can help save money on your energy bills, avoid costly breakdowns and keep your air clean!

When air conditioning equipment is not maintained properly, your energy costs can increase by as much as 20 percent. Regular maintenance is essential to keep your system operating properly and failing to maintain the system can shorten its life. You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular A/C preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severely hot weather when you need it most, and it can also keep your energy bill from getting out of control.

Peak Performance with an Air Conditioner Maintenance Plan

Regular maintenance can save money on your energy bills. Dirt on the A/C evaporator coil increases energy costs by about 5%, dirty furnace blower wheels reduce air flow by 30%, and when the refrigerant in an air conditioner is undercharged, it can reduce the efficiency by half. In addition, problems can be caught early and furnace repair or air conditioning repairs can be completed before the problem gets bigger.

Air Conditioning Preventive Maintenance Checklist

You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular A/C preventive maintenance is the best way to ensure trouble-free operation and peak performance. Annual maintenance is also important and should be done in the spring. It can help to avoid a system failure in severely hot weather when you need it most, and it can also keep your energy bill from getting out of control.

Outdoor Unit Checklist:

Inspect unit for proper refrigerant level and adjust if necessary
Clean dirt, leaves and debris from inside cabinet
Inspect base pan for restricted drain openings—remove obstructions as necessary
Inspect coil and cabinet—clean as needed
Inspect fan motor and fan blades for wear and damage—on older models lubricate as needed
Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage.
Inspect compressor and associated tubing for damage

Indoor Unit Checklist:

Inspect and clean blower assembly (includes blower housing, blower wheel, and motor)
On older models, lubricate motor and inspect and replace fan belt if needed
Check blower housing for lint and debris and clean as necessary
Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed
Inspect ignition system and safety controls—clean and adjust as needed
Inspect the control box, associated controls, wiring, and connections
Clean or replace air filters
Inspect conditioned airflow system (ductwork)—check for leaks

While Your System is Operating

Monitor system starting characteristics and capabilities
Listen for abnormal noise
Search for source of unusual odors
Monitor air conditioning for correct refrigerant charge
Measure outdoor dry bulb temperature
Measure indoor dry and wet bulb temperature
Measure high and low side system pressures
Measure temperature rise and adjust airflow as needed
Check vent system for proper operation
Monitor system for correct line and load volts/amps
Monitor system operation per manufacturer’s specifications
Provide system operation report and recommend repairs or replacement as necessary
