It’s summertime, and that means lazy days by the pool, cookouts, and…malfunctioning HVAC systems? This can bring your enjoyment of the season to a screeching halt, so let’s go over some of the main issues you might be seeing with your HVAC systems and a light at the end of the tunnel.

Noisy Operation

You expect cool, quiet comfort, but your air conditioning system is making unsettling noises. Here are the common culprits:

  • Screeching or squealing: This could indicate a faulty fan motor or compressor
  • Hissing: This is likely due to a refrigerant leak
  • Buzzing: Often caused by faulty electrical wiring or components
  • Clicking: Possibly a relay issue
  • Thumping and banging: Usually issues with motor assemblies or blowers

Erratic Operation

If your air conditioning system is shutting off unexpectedly or cycling frequently, it may be the thermostat sensor. This is near the evaporator coil, and if it’s faulty or misaligned it could be the source of your HVAC system’s erratic operation. A refrigerant leak might also cause uneven cooling, frozen coils, and lowered energy efficiency.

Bad Odors From Vents

If the drain pipeline is clogged, it will cause bad odors throughout the home. Common causes are dirt, dust, and algae. Not only does a clogged drain pipeline cause bad odors, but it will also develop mildew and mold.

Air Conditioner Unit Seizing Up

Seized air conditioning units are usually the result of a frozen evaporator coil. This happens when the air conditioner doesn’t get sufficient airflow, usually because of blocked ducts or vents, faulty fans, or dirty air filters. These are also the cause when an AC unit isn’t producing cold air.

Excessive Water Leaks

It’s normal for your HVAC system to have some water leakage outside, but if it’s excessive it usually means something is going on with the unit. This could mean you have low levels of coolant, a blocked drain pipeline, dirty air filters, or a malfunctioning condensate pan.
