If they persist or prove to be more complex, it’s time to call a professional HVAC company like Superstition Cooling. Our expert technicians will provide the necessary repairs and maintenance needed to ensure that your furnace runs smoothly and reliably.

Your Furnace Isn’t Blowing Hot Air

If your furnace is running but the air isn’t hot, you’ve got a problem. Here are some of the possible causes, along with ways to troubleshoot the issue:

Possible Causes

  • Clogged Air Filters: If your furnace’s air filter is blocked with dust and debris, it can inhibit the flow of heated air, diminishing the heat output. The filter should be changed each month since a dirty filter is the leading cause of HVAC issues.
  • Malfunctioning Thermostat: A faulty thermostat may fail to communicate the need for heat to your furnace.

Troubleshooting Ideas

  • Check and Replace Filters: Regularly check your furnace air filters. If they appear dirty or clogged, replace them with new ones. On average, filters should be replaced every month.
  • Thermostat Calibration: Make sure your thermostat is set to ‘heat’ and not ‘cool’, and that the temperature is set to a number that’s above room temperature. If your thermostat operates on batteries, make sure to replace them regularly.

Your Furnace Isn’t Turning On

When your furnace refuses to operate, there can be several causes. Let’s look at some of the most common issues and how you can troubleshoot them.

Possible Causes

  • Electrical Issues: Check if your circuit breaker has tripped or if the furnace switch is set to ‘off.’
  • Pilot Light Problems: If your furnace has a pilot light, make sure it is lit. An unlit pilot light will prevent your furnace from operating.
  • Lack of Maintenance: Neglecting regular furnace maintenance, including cleaning and inspection, can lead to a faulty system and, eventually, a broken down machine.

Troubleshooting Ideas

  • Inspecting Electrical Connections: Make sure all electrical connections, including the circuit breaker and furnace switch, are functioning correctly.
  • Relighting the Pilot Light: If the pilot light is out, refer to your furnace manual to relight it safely.

Furnace Diagnostic and Troubleshooting Tips

Furnaces usually display error codes or signals that can help diagnose the problem. Refer to your furnace’s manual to understand what each code means. There should be a key that contains each code along with a short message about the problem.

A homeowner or business owner should regularly inspect all the furnace components, including the blower motor, the heat exchanger, and safety switches, to ensure they are in good working condition. It’s highly recommended that you hire a professional like Superstition Cooling to perform regular inspections and maintenance on your unit to help you avoid costly repairs.

When to Seek Professional Services

While some furnace issues can be resolved at home, others might require professional attention. If your furnace is making unusual noises, emitting a strange odor, or regularly cycling on and off, it’s best to call the professionals at Superstition Cooling. These are signs of complex issues that are better handled by an experienced HVAC professional.
