St Charles Heating and Air Conditioning Company Tips: What Are the Causes of HVAC Airflow Problems?

If you’re having airflow issues with your St Charles heating and air conditioning system, do not worry—these are some of the most common problem your system can have, which means they are fairly easy to solve. However, if you ignore them for too long, they will strain the HVAC system, which can lead to a compressor failure. The compressor is an essential component of the system, and when it fails, you will more than likely have to replace the entire HVAC unit.

Some of the symptoms of airflow issues include:

  • Hot and cold spots throughout the home
  • Pressure imbalance—where you have doors slamming by themselves, drafty areas, or strange whistling noises
  • Weak or completely absent airflow coming from some of the vents
  • Warm air coming out of the AC system

So, what causes these issues?

Obstructed Condenser

This issue is very easy to fix on your own. The condenser unit for HVAC systems is usually located outside of the home, or in a separate mechanical room. Over time, outdoor systems will start to get clogged up and obstructed by leaves and other debris. Even units located in mechanical rooms can become obstructed by dust or fallen storage items. Once the condenser becomes obstructed, the HVAC system begins to overheat, leading to air flow problems and a host of other issues.

Blocked/Leaky Air Ducts

If you do not routinely replace your air filters, you may end up with blocked ducts. Dust will accumulate over time in your ductwork, and if the ducts are narrow enough, they can become clogged. This is a common problem in older buildings, as well as the issues of rats, mice, insects, or birds building nests inside the ducts. This will obviously lead to airflow problems throughout the home. On top of that, you have the issue of the ductwork cracking or developing holes, which will also cause leakage. The solution to this is a quick inspection from a professional St Charles heating and air conditioning company.

Blocked Vents/Clogged Filters

Sometimes, air vents may be blocked by furniture, which could lead to air flow problems. Make sure that all your vents and registers are open and unobstructed. This is a particularly common issue in office spaces, especially when people disagree on the best setting for the thermostat. Someone may move a piece of office furniture in front of a register because they are too cold, causing air flow issues in another area of the office.

You also have the issue of clogged filters. Replacing the filters is one of the most important HVAC maintenance activities that you can perform. Filters can become overloaded with dust and debris over time, and they can start to impede the air flow of the HVAC system, leading to hot/cold spots throughout the home.

Dirty Coils

Most air conditioner units have a condenser coil, which is designed to release heat that is removed from the home. It is located outside of the home with the condenser, which means that it is more vulnerable to dirt and debris. Over time, the coil will get dirty, making it harder for it to release heat. This, in turn, forces the AC unit to consume more energy in order to cool your home. This results in air flow issues, and potential damage to the unit. This is just one of the reasons why it’s important to hire a heating and air conditioning contractor in St. Charles to perform routine maintenance once or twice a year.
