BUSINESS Common HVAC Problems and How To Troubleshoot Them

HVAC ‘The air conditioning system is one of the most important parts of a home because it keeps the air cool and keeps you comfortable. Due to normal wear and tear or sudden problems, you may need to fix or replace your air conditioner at times. Here are seven of the most common problems with an air conditioner and how to fix them:

Malfunctioning Thermostats

If your thermostat is broken, your air conditioner or heater might not work right. Make sure that the settings for the airflow and the temperature control are correct. You can fix this problem by replacing the batteries or changing the settings. Follow the instructions on your thermostat, recalibrate it to ten degrees warmer, and clean it with a soft cloth to get accurate readings.

Loud Noises

There are many reasons why your HVAC might make loud noises like buzzing, popping, or clanking. If your air conditioner is making strange noises, the belt or fan motor is probably the problem. Buzzing can be caused by a loose part or a problem with the motor while popping can be caused by ductwork that is getting bigger. Clanking sounds suggest a problem with the blower assembly. Make sure that all of the air filters are clean and free of dirt and dust. If they need to be changed, do it the way the maker tells you to. Tighten up any parts or pieces of the air conditioning system that are loose.

Leaking HVAC Units

When air conditioners start to leak, it could be because the drain line is clogged. Use a wet hoover to get rid of any standing water in drain pans, and then look for cracks and holes. Small cracks can be fixed with a water sealant, or the pan can be replaced. Leaks can also be caused by dirty air filters, so replace them every two to three months to keep coolant from building up and causing damage. If the evaporator coil has a leak, it needs to be fixed by someone who knows how to fix air conditioners.

Uneven Temperature Distribution

If the temperature in a house isn’t the same everywhere, it’s likely because of a problem with the air ducts. Make sure that all of the air vents and registers are open and free of anything blocking them. If some rooms feel cooler or warmer than others, check the ductwork for loose connections or a buildup of dirt, which can stop air from moving through the system. Check your air filters and, if you need to, replace them. Add airflow boosters and dampers to the home to control the temperature of the air and make it easier to move around.

Broken Fan Motors

If the fan motor is broken, your air conditioner may stop working all of a sudden. Check to see if the air filters are clean and if the fan blades have any dirt on them. Also, check to make sure that the wiring for the air conditioner is correct and that it is securely connected to its power source. If you think the problem might be with the electricity, call a licensed air conditioning repair expert.

Inadequate Cooling Capacity

If your air conditioner isn’t making enough cool air, check the blower assembly and evaporator coil to see if they need to be cleaned or replaced. Check your air filters and change them if they are broken or clogged. Also, check the coils and fan blades for signs of damage and ensure that all air ducts are securely connected to the air conditioner.

Blown Fuse

If a fuse blows, your heat or air conditioning won’t work at all. Circuit breakers shut off automatically when they are overloaded, and blown fuses stop giving power. When there is too much electricity flowing through the circuit, the fuse gets too hot and breaks. Several things, like a broken thermostat, dirty air filters, or faulty wiring, can cause this. First, find the fuse that has blown in your system. Then, turn the unit’s power off and replace the blown fuse with a new one with the same amperage rating. Find and fix any problems that may have been going on that could have caused the fuse to blow. Clean the air filters and fix the wiring so it doesn’t happen again.

Air Conditioning Repair in a Nutshell

Some problems with your heating, ventilation, and air conditioning (HVAC) can be fixed by you, but most need to be fixed by a professional. Follow the directions and stay safe if you fix your air conditioner yourself. By taking care of HVAC air filters, coils, electric motors, air ducts, and fuses regularly, they can work better. If you have any problems or the repairs are too hard, you should call a certified technician.
