AC Repair Des Peres MO

Tips for Troubleshooting Common AC Problems

If something goes wrong with your air conditioner in the summer, your home can quickly start to feel more like the Sahara Desert than a relaxing place to retreat from the weather. Here at Advantage Air, we offer AC repair Des Peres MO. However, your heating and cooling system may only need some minor maintenance instead of extensive repairs. Here’s how to troubleshoot some of the most common AC problems you may encounter as a homeowner.

Air Flow Problems

If you’re having issues with air flow through your AC units, you may simply have a dirty air filter. Here are some things you may want to check for before you call us for a furnace and AC repair appointment in St Louis MO. All of these problems are common indications that your air filter needs replacement:

  • Low airflow from vents
  • Frozen evaporator coil
  • Rising energy bills
  • Hot or cold spots throughout your home
  • Ice on the refrigerant lines

If you see any of these problems, try replacing your air filter. If that doesn’t solve the problem, let us know. We know how to quickly get to the bottom of most problems HVAC systems commonly have.

Broken or Malfunctioning Thermostat

Sometimes, when furnaces and AC systems seem to have problems, the real problem lies in the thermostat. If your thermostat is broken or malfunctioning, it may cause:

  • Hot or warm air coming from air vents even when you have the AC on
  • AC won’t turn on at all

The problem may even be that you’ve forgotten to the turn the “heat” switch over to “cool” on your thermostat.
