1) Change Your Filter

A clogged air filter can lead to various heating problems, such as blowing cold air or reduced efficiency. Swap it out every 30-90 days, depending on usage and filter condition. If you’re not sure what size filter you need, talk to our team or see if the size is listed on the existing filter.

2) Check Your Pilot Light

If your furnace or boiler is non-operational, ensure the pilot light is lit. Attempt to relight it, check the gas valve, and clean the sensors near the light. If the issue persists, especially with the gas on, it’s time to consult a professional to avoid handling gas lines. If you’re not sure how to light it, let a professional show you how before you try yourself.

3) Look for Leaky Ducts

If the air from your vents feels less warm, potential leaks in the ductwork might be the culprit. Use a lit stick of incense to trace leaks, especially in basements or crawl spaces. Seal any leaks discovered and observe the furnace’s performance.

4) Test Your Thermostat

Sometimes, the problem lies with the thermostat rather than the heater. Disconnect it from the wall to verify proper connections. If the issue persists, consider replacing the thermostat. You can get replacements at your local hardware store. If you want help choosing the best new thermostat for your needs, call us to get the advice you need.

5) Flip Your Circuit Breakers

If nothing seems to work, inspect your circuit box. A damaged or tripped breaker for your furnace can disrupt the system. Reset or replace the breaker to restore functionality. If you can’t get the breaker to work, talk to an electrician about replacing it or about other possible circuit problems.
