A central air conditioning system can offer years of satisfactory cooling with comparatively little upkeep. But a seasonal start-up check and periodic upkeep is recommended. Some you can do, others need a professional. The quantity of do it yourself air con upkeep a property owner can do is restricted.

Homeowner Tick list
For house owners in colder climates, now’s the time to get set for the heat of summer. But there are a couple of steps that will help the system operate trouble-free and decrease the potential for consequential damage. Making sure adequate airflow is maybe the most significant homeowner responsibility.

Following manufacturer instructions, homeowners can typically :
Clean or replace the filter ( s ) regularly.
Keep leaves and other debris off the condensing ( outdoor ) unit.
Keep the condensing coils clean by ( awfully ) carefully brushing and hosing them.
Keep plants and other plant growth that might obstruct airflow at least 18 inches
Away from the condenser.
Maintain insulation on ductwork in attics and other unconditioned areas.
Check the condensate drain for any hint of blockage or seepage. Water should be
leaking from the end of this drain line when the unit is running. If no dripping is noted, check at the indoor unit for any signs of seepage.
Keep room input and return registers clear of furniture or other obstructions.

Selecting Trained Professionals

If your air conditioner needs more than the regular maintenance explained here, consult a professional air conditioning specialist. A well-trained pro can provide a comprehensive pre-season or maintenance evaluation and servicing as needed. Insufficiently trained service technicians forsake proper diagnosing procedures and frequently only perform stop-gap measures to keep a unit going.

At an effective minimum, a technician should :

Check that the system contains the proper quantity of refrigerant. Such short-sightedness can have a drastic effect on other parts leading to consequential failure of the whole system.
Test for refrigerant leaks.
Check for and seal channel seepage.
Clean the blower components.
Measure airflow through the evaporator coil.
Verify the right electrical control sequence.
Check electrical terminals ; clean and tighten connections.
Oil motors and check belts for tightness and wear.
Check the condensate system for backup or leaking.
Check operating temperatures and pressures.
