Heater Repair Tips from the Pros: What to Do Before You Call

Before reaching out for professional repairs, there are a few steps you can take to troubleshoot your heater:

  • Check Your Thermostat: Make sure your thermostat is switched to “heat” mode and set to a temperature higher than the current room temperature to activate your heating system effectively. If it’s a programmable thermostat, double-check the schedule and settings to ensure they’re set correctly. A malfunctioning thermostat could also require new batteries or recalibration.  
  • Inspect the Power Supply: Verify that your heater receives power by checking the breaker or fuse box for tripped switches or blown fuses. If your heater has a power switch, turn it on. For gas furnaces, ensure the pilot light is lit. If issues persist, it may be time to consult a professional.  
  • Replace the Air Filter: A dirty or clogged air filter can block airflow, diminishing efficiency and reducing your heater’s ability to provide warmth. Check the filter and replace it if it’s dusty or clogged. Regularly changing the filter not only ensures better airflow and improved heating but also enhances air quality, extends the system’s lifespan, and helps keep energy costs in check.
  • Look for Blocked Vents: Take a walk through your home and ensure all vents and registers are open and unobstructed. Move any furniture, rugs, or debris blocking airflow to help your heating system distribute warm air evenly and efficiently throughout your space. Blocked vents can prevent proper airflow and cause uneven heating, making certain rooms colder than others.  
  • Listen for Noises: Pay attention to any unusual sounds, such as banging, rattling, or squealing, coming from your heater. These noises can indicate loose parts, motor problems, or airflow restrictions. Noting these sounds and when they occur can help a technician quickly diagnose and fix the problem.

Taking these steps may resolve minor issues or provide helpful information for our team when you call. Remember, our experts are here to help if these tips don’t solve the problem. Schedule a repair today.
