There are few things as annoying as having your air conditioning break down in the height of summer. Here are some troubleshooting tips to get your AC working again.
Check your thermostat
Make sure that your thermostat is on the right setting. If you have it set too high, it may not turn on the AC. If your thermostat has a timer setting, check it to make sure that it’s set to turn on when you’re at home.
Check your filters
One of the most common causes of poor AC performance is a clogged filter. If you use disposable filters, they need to be changed once a month. Re-usable filters typically need to be cleaned monthly too, although they may need more frequent attention if you live somewhere with a lot of particulate matter in the air.
Check your ducting
If you have a central AC system, check that the ducting isn’t torn, folded or blocked. If there are holes or blockages in your ducting, the cold air from your AC can’t reach the spaces you want to be cooled down. You should also make sure that all the vents and registers are open and unblocked.
Check airflow around your unit
Your AC needs good airflow to work properly. The vents at the back need to be clean and free of dirt and corrosion; otherwise your unit won’t be able to get rid of hot air. Anything that blocks the airflow around your unit needs to be removed. This can include shrubs or climbing plants that can grow over the exterior of your AC unit.
Check your AC coils
The coils of your air conditioner need to be clean and free from any obstructions. If they’re covered in condensation, leaking coolant or corroded, your unit may need professional attention.
If you’ve tried all these tips and your AC still isn’t working, it’s time to call in a professional. Find a reputable AC repair company in your neighborhood and have them inspect your system. Even if you do find that you’ve solved the problem yourself, it’s a good idea to have a professional HVAC inspection at least once a year. This will help keep your unit running as it should and can save you money on repairs and replacements later on.
