If your home's heating and air conditioning unit stops working, you can do a few things to try and fix the problem. Frst, make sure that the power is off to the HVAC unit. Next, check the breaker box to see if the circuit has a problem. If the breaker box is okay, you may need to call a professional to repair or replace the HVAC unit.
What could cause an HVAC unit to stop working?
When an HVAC unit fails, its potential causes can be numerous. Here are eight of the most common:
A clogged filter. This is the most common cause of an HVAC unit not running, and it can often be corrected by a homeowner using a plunger.
The motor is faulty. It will automatically shut down if the motor doesn't have enough power to run the blower, fans, or compressor.
A broken thermostat. When this goes bad, the heat or air conditioning won't turn on as intended, leading to overheating or freezing inside the home.
Faulty wiring in the unit or Home Automation System (HAS) control panel. This could cause a false sense of security and overuse of energy, leading to a shutdown.
The HVAC system doesn't have enough refrigerant. If the refrigerant isn't being used as expected, it will cause a shutoff in the unit.
A unit that has been installed improperly by a technician not familiar with the entire system.
A unit located in an area with poor ventilation, such as a closet or attic.
Improperly installed or poorly maintained systems can cause many problems for homeowners.
Troubleshooting HVAC unit problems: Tips and tricks
When your home's heating and air conditioning system isn't working as it should, you may wonder what to do. Troubleshooting HVAC unit problems can often be daunting, but with some tips and tricks, it can be a lot easier. Here are some things you can do to get your system back up and running:
1. Check the power supply.
Ensure that the power to the unit is adequate and that there are no issues with the wiring or connections. If the power is questionable, replace any damaged parts of the electrical system before troubleshooting the issue further.
2. Check for faulty parts.
Sometimes, a defective part is the source of the problem. If you are unsure as to which parts are faulty, you may want to replace all of them at once. This will ensure that the problem is fixed and can be avoided.
3. Check for damage to the unit.
If the system had no power, one of two things could have happened. Either the power cord has been damaged and needs to be replaced, or there was a power surge that caused some of the wires in the system to become damaged. If this is the case, you will need to replace all damaged wires.
