Benefits of an A/C Tune-up

Posted 03-04-10 in Air Conditioning

Murphy’s Law states that “if a thing can go wrong, it will … and at the worst possible time” and the Law of Moving Parts states “that moving parts someday will wear out”. If you have not had your air conditioning system serviced in a while these two laws may apply to you!

Your air conditioning system has many moving parts and just like your car needs to be serviced on a regular basis to keep it working reliably (safely and efficiently, too!). You don’t want to be stuck on the hottest day this summer waiting for the service technician (during their busiest time) to come fix your a/c unit, when a simple tune-up could have prevented the need for this emergency service call.

Below are some important checks that are made during an Air Conditioner Service call and how they benefit you:



Work Performed Benefit
Check thermostat Improperly calibrated thermostat affects comfort and operating costs
Start unit Verify unit is operational before the hot weather hits
Check return air filter Restricted filter causes unit to waste energy and shortens the life of your compressor
Check and replace air filters Dirty filters decrease efficiency and comfort
Evaporator coil cleaning Dirty evaporator coils decrease efficiency and can lead to compressor failure
Check condensate drain A plugged condensate drain can cause expensive water damage
Check condensate pan and fittings for leaks A cracked pan or loose fitting can cause expensive water damage
Check blower wheel Dirty blowers reduce airflow, increase operating costs and can lead to compressor failure
Check blower motor amp draw Ensures optimum performance; protects equipment
Lube motors & bearings Improperly lubricated rotating equipment will eventually fail
Check belt, pulleys and alignment Avoids costly service calls and save money on utility costs
Examine parts for visible wear Avoids costly service calls
Examine all electrical connections Extends life of system and ensure safety
Remove debris around outside unit Promotes efficiency. Prevents damage to equipment.
Clean condenser coil Dirty condenser coils raise refrigerant pressures Increasing electrical costs.
Check condenser fan and motor amp draw Ensure optimum performance; protect equipment
Check all safety devices Keeps unit in safe operating condition
Test refrigeration metering device Blockage or improper operations of metering device reduces cooling capacity, increases fuel costs, and shortens system life.
Check compressor amp draw Ensures optimum performance; protects equipment
Wax outdoor unit For weather protection and extended life.
