Common AC Problems in St. Louis, MO

Homeowners are likely to encounter an air conditioner problem at some point and will require AC maintenance or AC repair if the issue progresses. To ensure that an air conditioning problem doesn’t develop into something more serious, it’s important to be able to properly identify and address the issue. As always, Design Aire, your trusted St. Louis HVAC company, can help you with your AC system needs should any of these problems arise.

Moisture Buildup

Although moisture typically accumulates in functioning air conditioners as a normal part of the cooling process, too much moisture can indicate leakage or cause mold to grow which is a common air conditioning problem. Oftentimes, excess moisture indicates that you’ll need an AC replacement.

Cold Air Isn’t Blowing

If your air conditioner ceases to blow cold air, or has inconsistent cooling, this is one of the earliest signs that the unit is in its final days. Our air conditioning repair techs may be able to help resolve the issue by taking certain steps such as unclogging drains, but oftentimes a complete AC replacement is needed to reach peak efficiency again.

Bad Smells from AC

An air conditioning unit should produce odorless cold air. If you notice any strange smells coming from your air conditioner, you may be able to get rid of them through a simple fix. However, bad smells could also be indicative of a serious underlying issue. Reliable air conditioning services will be able to pinpoint the problem and provide the right fix.

Odd Noises

Air conditioning units should be relatively quiet, so any squealing, squeaking, or grinding sounds could hint at a serious problem. It’s often best to consult with our technicians to diagnose the root cause, wether it is a common air conditioning problem or something more serious.

Increasing Energy Bills

Rising energy expenses during the summer can be alarming, and they may result from an inefficient air conditioning system. If you notice that your bills keep increasing each summer, you may need to consider getting a replacement.

Faulty Wiring or Thermostat

If your thermostat is blank or isn’t working or wiring within your AC system is faulty, your unit may not get the power it needs for optimal functionality, or it can result in a tripped circuit breaker. A Design Aire technician can help determine if either is a problem.

Failing Fans

If the outside fan in the AC unit isn’t working the way it should, the unit’s compressor could overheat. A nonfunctioning fan normally indicates that cleaning is in order, as dirt, parts from nearby plants, and other debris can get into the unit and block the fan or make it dirty which is a common AC problem and that can be fixed quickly with an HVAC service.

Low Freon Levels

A decrease in freon levels could indicate certain problems such as a refrigerant leak, but it can be difficult to identify the specific issue. In some cases, you may need to replace the entire unit if you can’t maintain a consistent freon level.

Frozen Coil

Any coils in the unit that are frozen could be signs of an airflow problem, which may include blockage of the return air ductwork or a filthy air filter. We can examine the unit to determine if there are any airflow issues with the evaporator coil and the cause behind them.
