Proper Maintenance is the Key to Preventing ProblemsAsk any HVAC technician, and they’ll tell you the same thing: proper maintenance is essential. Fortunately, there is a lot you can do as a homeowner on this front. You could even say that HVAC maintenance is just a part of owning a home. There are many myths surrounding HVAC systems, so a basic understanding of how they work can take you far. There is a lot to know about your AC system, but don’t think you need to be a certified technician to take care of basic maintenance. Here are some tips to get you started:
- Keep a regular maintenance schedule
- Change your air filter regularly
- Inspect your refrigerant lines monthly
- Clean your outside condenser coils to prevent dust build-up
- Have a trusted HVAC team on call when emergencies arise
Common Problems with HVAC SystemsWhile HVAC units can be complex, common issues are pretty easy to understand, diagnose and resolve. Below, you will find some underlying causes for why your air conditioner is not working. Keep in mind that some of these issues you can take care of yourself. Others will need the help of trained professionals. Your HVAC system has some expensive parts, and an untrained hand can ruin them in an instant. Moreover, since HVAC systems run on electricity, you should take proper safety precautions. Now that we’ve got the safety talk out of the way, here are some common problems you might face when dealing with a non-functioning AC unit.
Low RefrigerantRefrigerant is a vital component to your AC compressor and overall cooling system. There needs to be an exact level of refrigerant to keep things operating smoothly. Too much, or too little, can cause your AC to perform poorly or shut down completely. When you are low on refrigerant, it means your AC compressor is working extra hard to cool down the condenser coils. If this happens for too long, it can cause extra wear and tear on your compressor. Often, this will lead to a complete failure. If your unit is running, but warm air is coming from the registers, low refrigerant might be the culprit.
Frozen Evaporator CoilsWhen your evaporator coils start collecting too much dust, they risk freezing over. This makes cleaning your coils an essential part of maintaining your unit. You can tell almost immediately if this is the issue by the visibly frosty coils. You may even be dealing with evaporator coils covered in ice. Icy coils will cause your other AC components to work harder. Usually, your fans will have to operate overtime to make sure things are running smoothly. Much like other issues, if this persists, it could mean broken fans down the line. Turn off your system and let your coils defrost. While everything is off, check for obstructions to airflow, as this is a common source for frosty coils. Use a coil brush to clean any dust or debris from your unit.
Fan ProblemsIf your fans aren’t working, the first thing you want to check is your breaker box. If there are no tripped breakers, it might mean you need to change your air filter or clear obstructions in your ducts. You have an indoor fan and an outdoor fan. You will need to check both. Make sure to listen for the fan motor. If it’s not running, it might mean it’s burnt out. If this is the case, it will need replacing.
Thermostat IssuesFixing a thermostat is the best-case scenario. If your thermostat display is off or the display is not showing correct information, it might be time to replace the device. If your thermostat isn’t working, it means that the signal that goes to your AC system never reaches the unit. This is good news, because it usually means a more serious issue is off the table. Additionally, you might experience a temperature disparity between what is on your thermostat and the room’s actual temperature. This could be due to an improperly placed thermostat.
Getting Your HVAC System Inspected RegularlyAs a homeowner, there is only so much you can do to prevent problems from arising. Getting the help of a qualified AC service in Grand Prairie, TX, can help when issues demand a more experienced hand. There are a surprising amount of fail points in an HVAC system. There is a reason why HVAC technicians need years of training. Having regular maintenance done on your AC unit has benefits. They include:
- Longer lifespan of parts
- Less energy consumption, which means lower energy bills
- Greater comfort when your HVAC system is running optimally
- Fewer repairs and costly fixes
