Have you scheduled your professional air conditioning maintenance appointment yet?

What’s Included in Professional Air Conditioning Maintenance?

If you have a qualified HVAC technician inspect your air conditioning system, they should check all of the following components:

Thermostat Settings

This ensures your thermostat is installed properly and away from all heat sources, including solar rays, light bulbs, and heat-producing appliances.

Tighten all electrical connections

This ensures your electrical connections are operating safely. Checking and tightening electrical connections also helps improve the lifespan of your heating and cooling system.

Lubricate moving parts

This ensures that you aren’t causing any unnecessary damage to moving parts with friction. Lack of lubrication causes system parts to break down more quickly, requiring more frequent repairs and/or replacements.

Check and clear condensate drain line

This ensures that your condensate drain line is clean and clear. If your drain line becomes clogged, this can cause water leaks and other moisture and wetness problems. If you don’t want bacteria, water, and mold in and around your HVAC system, call your HVAC contractor to check and clear your condensate drain line. Leaks can also be caused if you have a cracked condensate drain pain. Your HVAC contractor will also be able to repair or replace any leaking condensate drain pans that you may have.

Check system controls

This ensures proper cycling and safe operation for your HVAC system. It’s important to heck if your system is starting, operating, and shutting off properly.

Inspect, clean, and change your air filter

This ensures that you have a working and clean air filter that is suitable for your existing system. Although you are able to change your filter yourself (and you should!), your HVAC contractor might point out a better filter or filtration system that you should be using.

Fix refrigerant leaks and recharge refrigerant (if necessary)

This ensures your air conditioner’s refrigerant charge and make sure it meets manufacturer specifications –too much or too little refrigerant causes problems with the moving parts of your HVAC system, including the compressor and condenser.

DIY HVAC Maintenance

Change your air filter every 30-90 days

Check your air filter every 30 days by holding the filter up to a light and observing if any light can pass through. If it seems clogged, it is—replace it!

Clean around the outdoor condenser unit

Your outdoor condensing unit (aka heat pump) needs proper airflow in order to function effectively and efficiently. Inspect your outdoor heat pump every 30 days for clogs and debris. Clean off leaves, grass clippings, twigs, and other debris from your outdoor heat pump. Maintain a minimum 2-foot clearance around the entire unit. If you have bushes or other plants encroaching on the heat pump, trim them back.

Inspect your thermostat

Make sure your thermostat is away from all heat sources, including solar rays from the sun, lamps, and heat-producing appliances.

Maintain condensate drain lines

Your trained HVAC technician will clear your condensate drain line during their annual maintenance visit, but it’s also a good idea to keep your condensate drain line clear with a stiff wire and some bleach. Simply locate your condensate drain line, unscrew the top of the vertical PVC pipe, pass a stiff wire through it, and then pour a cup of chlorine bleach down the pipe. Do this in the beginning of every spring season to help keep your line clear.

Schedule professional HVAC maintenance in the early spring

Professional maintenance is the best way to keep your air conditioning system healthy, efficient, and long-lasting. You wouldn’t neglect car maintenance for years, so why would you ignore professional HVAC maintenance? In addition to lowering utility bills and increasing comfort and indoor air quality, annual professional maintenance also guarantees that your manufacturer’s warranty remains in effect.
