4 Common HVAC Problems You Need to Look Out For

The HVAC unit is the most crucial part of a building, as it helps to maintain an optimal temperature in the room. Additionally, it will also help to improve the ventilation in the room, helping to improve the air quality. One major concern with HVAC units is that it must be maintained meticulously. This is to ensure that it’s able to produce the same level of air quality and temperature without consuming too much energy. Therefore, you need to make sure that you always keep the unit in the best condition. With that said, here are four signs that tell you that you need to do some repairs for your HVAC unit:

Obstructed airflow

The first and most important sign you have to look for is restricted air flow. This can be attributed to many issues, from the shifts and bends in the unit, dirt buildup, to clogged filters. Therefore, the best thing you can do when you start to feel that the air distribution is not optimal is to open the front case and remove the filters to see if there’s any dirt buildup inside the unit. If you use a flashlight to shine inside the grids, you will be able to see the black spots inside the air dispenser. This may be the thing that’s disrupting the airflow. If these dirt buildups become frozen, it will be a pain to remove. You will need to make sure that you take care of it before the winter comes. If the buildups are in an accessible place, you can use a cleaning stick and a wet piece of cloth to get rid of it. If not, you will have to call a professional to help you with it.

Serious water damage

Another significant concern with HVAC units is water damage. This is particularly a pressing matter during the rainy months and hurricane seasons. If the exterior unit is located near the gutters, the water may spill onto the unit and seep into the compressor. This can cause the unit to short circuit. This will cost you a fortune to repair, especially if the compressor is damaged. Therefore, you will need to install some water protection on the unit to prevent the water from dripping onto the compressor. Additionally, you should make sure that you check the compressor during the winter to make sure that there’s no ice shard forming on the compressor. That may cause the fan to take on unnecessary weight, which can cause it to become bent.

The system doesn’t produce any cool air

Obviously, when the AC doesn’t produce any cool air, it’s a sign of a problem. If you notice that the unit doesn’t generate any cold air even when you have it on the highest settings, the problem may lie in the refrigerant level. Most of the time, this can be done very easily by refilling the refrigerant tank. This will help to solve around 70% of these cases. However, you should keep in mind that refrigerants don’t just run out by itself regularly. You may have to fill it once every couple of years.  If it’s any more often than that, there may be a leak in the refrigerant pipe.

Continually running the heat pump

This is a rare issue, but it does happen from time to time. If the heat pump is continuously running regardless of the temperature outside, the problem may lie in the thermometer. When an automated heat pump unit is unable to determine the temperature, it will assume that it needs to keep working, which can lead to an expensive energy bill. Additionally, it can also be caused by ice buildup on the compressor. This will make the heat pump thinks that it’s colder than it actually is.
