5 Common A/C Problems
Posted: June 30, 2016
Summer’s almost here – which means it’s just about time to crank up the A/C to do battle with the elements in what is expected to be a scorcher of a season.
The question is, will your A/C be up for the challenge when you need it most? Before we hit triple digit days in July, it’s a good idea to give your A/C a trial run (and a good time to schedule a tune-up, if you haven’t done so already).
If your A/C isn’t running at all, check out our troubleshooting guide.
If your A/C is running, but not as efficiently or cool as you think it should, try these measures:
- Make sure filters and coils are clean – Dirt can cause a compressor or fan to overwork. Keep air intakes clear to ensure adequate airflow.
- Make sure windows and doors are closed – if your A/C is overworking unnecessarily, it could lead to inefficiency (and eventually costly repairs).
- Look for efficiency and airflow issues – If you notice poor airflow from vents and higher than usual bills, it might be time to get your system checked. Improperly maintained equipment can lose 5-10 percent efficiency or more every cooling season. Duct leaks can also sap cooling performance.
- Make sure your A/C unit is right-sized – If you’ve built an addition to your home and haven’t upgraded your air conditioner, it may have to work too hard to cool your space. The same unnecessary wear and tear can occur if your unit is oversized, since constant on/off cycling will tax the compressor and fan controls.
- Check for refrigerant leaks – If your refrigerant is low, it’s probably due to poor installation or a leak. Either way, you’ll need a trained technician to service your cooling system. After testing the repair, your technician can recharge your system with the right amount of refrigerant.
