Your HVAC system is essential for keeping your home comfortable year-round. But like any complex system, it can run into problems from time to time. Before calling in the professionals, there are a few common HVAC issues you can troubleshoot on your own. Here’s a quick guide from team here at 4 Winds AC and Heating to help you identify and possibly fix simple problems, saving you time and money.

System Won’t Turn On

Possible Causes:

  • Tripped Circuit Breaker: Check your home’s electrical panel. If the HVAC breaker has tripped, reset it.
  • Thermostat Issues: Make sure it’s set to the correct mode (heat or cool) and temperature. Aslo, check the batteries if it’s battery operated.
  • Blown Fuse: Look for a blown fuse in the HVAC units control board.

What You Can Do:

  • Reset the circuit breaker.
  • Replace thermostat batteries.
  • If the fuse is blown, replacing it may restore function, but call a pro if it blows again.

Uneven Heating or Cooling

Possible Causes:

  • Blocked Vents: Furniture or rugs can obstruct air flow.
  • Dirty Air Filters: A clogged filter reduces airflow, reducing system efficiency.
  • Leaky Ductwork: Air can escape before it reaches certain rooms.

What You Can Do:

  • Ensure all vents are open and unobstructed.
  • Replace or clean your air filters (typically every 1-3 months).
  • If problems persist, have your ductwork inspected by a technician.

Strange Noises from the Unit

Possible Causes:

  • Loose Components: Rattling may indicate a loose screw or panel.
  • Debris in Outdoor Unit: Leaves or twigs can cause loud clanking.
  • Motor or Fan Issues: Screeching or grinding can signal a failing motor or fan belt.

What You Can Do:

  • Tighten any loose screws or panels.
  • Turn off the system and remove visible debris from the outdoor unit.
  • If the noise continues, call a professional to prevent further damage.

AC Blowing Warm Air/Heater Blowing Cool Air

Possible Causes:

  • Thermostat Set Incorrectly: Make sure it’s set to “cool” in summer and “heat” in winter.
  • Dirty Coils: Dirty evaporator or condenser coils can impair function.
  • Refrierant Issues or Pilot Light Out (for furnaces): These require professional attention.

What You Can Do:

  • Double check your thermostat settings.
  • Schedule a coil cleaning as part of regular maintenance.
  • If refrigerant is low or the pilot light is out, contact an HVAC technician.

Water Leaks Around the Unit

Possible Causes:

  • Clogged Condensate Drain Line: Water may back up and leak out.
  • Frozen Evaporator Coils: Melting ice can cause excess water.
  • Improper Installation: Poor drainage setup can lead to leaks.

What You Can Do:

  • Try clearing the drain line with a wet/dry vacuum.
  • Replace air filters to improve air flow and prevent freezing.
  • For persistent leaks, schedule a professional inspection.
