As a general rule, an AC unit should be serviced at least once a year—usually in spring—in order for it to perform at its best. If you want to get a head start on things, or if you have been having some issues with your system, or maybe you just want the reassurance that your unit will be serviced before the heavy summer heat hits, it may be wise to call a professional AC technician early to get an appointment booked. After all, it’s going to soon be peak-cooling season for all your neighbours, as well.
There are, however, a few tasks you can carry out prior to contacting a professional. Depending on the model, type of unit and manufacturer’s label, you may need to perform some of the maintenance requirements listed below.
Do it yourself!
Before beginning, consult an AC technician or your manufacturer’s label to establish any necessary pre-cautions or protective gear needed while carrying out maintenance on your cooling system.
Clear grass clippings and leaves away from the outdoor unit
Dirt and debris can infiltrate the system. These particles can obstruct the clear airflow path needed by your unit to perform effectively. You can also clean your condenser with a commercial coil cleaner.
Keep vents and ductwork clear of any obstruction to the system’s ability to deliver air
Move furniture, drapes or anything that may be impeding the cooling system’s ventilation process.
Make sure the ventilation grills that supply-air and return-air are open.
Check the thermostat
Ensure the correct program setting is chosen.
Replace batteries in thermostat, if needed.
Test the accuracy of your thermostat with another temperature gauge. If difference between the two occur you may need to recalibrate or to reset your thermostat.
Check circuit breakers
Make sure the breakers are set to ON and that fuses have not blown
Clean air filters, fans, and coils
Air filters, fans and coils have a great impact on the quality and efficiency of proper airflow throughout the system, affecting your comfort. If left unmaintained, damage to the compressor can occur. This costly repair is avoidable when you clean the air filters, fans and coils once every season.
Oil the fan motor
Depends on your type and model of cooling system. Consult your manufacturer’s cleaning instructions.
Clean condensate drain holes or tubes that may be blocked with debris
Press unit’s reset button, if available on model
This could possibly resolve some minor mechanical issues involved in the system’s inefficient performance.
