Seasonal air conditioner maintenance is the most important factor in extending the lifespan and maintaining the efficiency of your central air conditioning system. Ordinary wear and tear, especially dirt and grime buildup, can cause your AC to overwork, struggle, overheat and eventually break down.
Keeping everything clean will help you catch any smaller problems before they become serious. Something as innocuous as a layer of leaves on your outdoor unit can eventually cause your entire system to fail. So to keep everything in good shape, here are a few tips.
Change filters every 4 weeks.
This is the most important chore for your indoor air quality.
Old, dirty air filters fail to filter your air. What you breathe at home won’t be as clean as it ought to be, and could go as far as to cause respiratory problems. Dirty air filters allow dirt and grime to build up in your ducts, which can lower the overall efficiency of your system and harbor microbes and mites that can multiply and get into the air in your home.
Every 2 paycheques, replace or clean your air filters.
- For 1″ filters, look for one that you can’t see through when you hold it up to the light to make sure it’s actually doing the job in the first place
- For larger washable filters, thoroughly rinse and dry them every 30 days. Swapping between 2 filters every month is easiest.
Clear the drains.
As your air conditioner keeps the house cool, condensation builds up in the system and drains through a series of tubes. If left stagnant, these pipes grow ground for mould and fungus, which can spread and clog your whole drainage system.
Once a year, as part of regular air conditioner maintenance, we will use a high powered vacuum to suck everything out of the pipes. To prevent the problem in the first place, you want to visually inspect the drain at least once a month. If there’s a buildup of liquid in your drain pan or in the pipe, do your best to remove any debris that may be clogging the outlet.
To keep gunk from growing in the first place, every three months you should add 1/4 cup bleach mixed with 3/4 cup water directly to your drain line’s access port (usually a T-valve). If the plug on your access port has a wire coming out of it, make sure to switch off your air conditioner’s breaker before you remove the cap, and be sure to replace it when you’re done.
Clean that condenser.
This is the the #1 reason for early-summer emergency calls to your ClimateCare technician.
During the off season, your condenser can get clogged with leaves, dirt and other gunk. This hinders circulation and can actually keep your air conditioning unit from cooling at all.
On the first of every month, visually inspect your air conditioner’s outdoor unit. Trim back any grass, weeds, hedges, or other plants, and remove or gently brush away any leaves or dirt stuck inside. Switch off your air conditioner and rinse the outside surface. A garden hose with a spray nozzle works just fine, as long as you spray from top to bottom.
Get new batteries.
We will calibrate your thermostat as part of the annual air conditioner maintenance, but if it goes out between routine checkups, the batteries are pretty easy to replace yourself.
Some thermostats have flip open battery covers, but usually you’ll have to gently pull the thermostat or its faceplate away from the wall. Just swap them out and pop the thermostat back in place – but make sure you shut off your thermostat’s breaker before you start to make sure you don’t get shocked.
There you have it! You can have a hand in maintaining your home comfort equipment without being an expert.
