What To Do If My A/C Stops Working
August 15th, 2017 by kcunningham
When your air conditioning system suddenly stops working during the summer season it can be an agony for the majority, if not all of the household. There are several different types of problems if the A/C stops working. Some of the most common ones are when the A/C is not working at all, A/C not cooling well but runs, room temperature can be too hot or too cold, water leaks from the device, or it makes strange noises.
Before you contact any HVAC technicians you can actually do some checkups yourself to save money. There is a lot of DIY troubleshooting depending on the level of damage. Here are some guides that you can try.
If your air conditioner does not turn on
If you have verified that the unit is getting power, you may have a defective control board. Most modern window air conditioners use an Electronic Control Board, or commonly referred to as a PCB, to control the individual components of the unit. If the fan or compressor circuits do not turn on, then the control board may be defective. Check the user manual for proper operation and verify that you are getting power to the unit before condemning the control board. Some control boards may have an internal fuse on them, so check for a blown fuse and replace with the same type and rating if necessary.
If your central air conditioner will not cool but you can hear it running
The unit may just need to be cleaned. Whether or not this is the cause of the problem, it’s the first remedy to try. Plan to do this on a relatively warm day. With the power off, put your hand on the compressor, if it feels hot, then it’s running, and you have lost charge. Do not let the system run like this. If the compressor is at room temperature, then you can check the wires to make sure it has not come undone or broken. Now if it’s low on charge, you will have to call a pro in to fix the problem.
It is best if you double check the basics before contacting the experts. Take note on when is the right time to call them if you are someone who is into DIY. Cleaning your air conditioner is something you can do on your own, provided you have a basic understanding of the parts of the unit. But any time you need to address the coolant, you need the help of a professional HVAC contractor. If you’ve already done some basic troubleshooting and the problem still exists, you need to hire an HVAC contractor.
Monitoring your A/C maintenance can help prevent these types of breakdowns. Keeping your air conditioner’s coils clean and your air filter changed when needed can keep the running temperatures of your unit down, thus helping to keep your own temperature down when the summer comes calling, making everyone in the household merry and nice.
