You can always Contact Us now for immediate assistance

• The thermostat does not work. One of the most common issues when it comes to the furnace is a malfunctioning thermostat.

• Flickering or weak pilot light. If your pilot light changes at all, you should call your local and trusted furnace technician. This could mean there is excessive carbon monoxide in your furnace and can turn into a dangerous situation and should be fixed immediately.

• Dirty filters. The air filter should be changed once a month to keep your furnace running properly. A dirty air filter can lead to reduced airflow in your heater causing your heater not to run properly.

• A cracked heater exchanger. The heater exchange separates the warming flame from the air, ensuring that your furnace runs safely, which can be a costly fix. Unfortunately over time the heat exchanger can crack if the air filter doesn't get changed. If the furnace goes out, call a licensed furnace technician to diagnose your furnace.

• Blower belt. The blower belt is part of the motor that helps keep the fan running. Over time these will sometimes start to fray or even break. This is usually noticed by a high pitched squealing sound from the furnace as it runs. Getting the belt replaced will help improve the performance of your heater fan.

• Over-cycling. If you notice that your heater is continually cycling on, even if it recently just turned off, this can be a sign that your limit switch is malfunctioning. You may notice your furnace to be continually blowing, even when it wouldn't be. This again will have to be diagnosed by a professional HVAC technician.

• The furnace isn't blowing. A few different issues could cause this. The primary issue is to ensure that the blower isn't clogged, to do this, make sure the blower area is free from any debris that may be clogging the area. Next would be to see if there is a flashing red light on your blower, if you see the red flashing light, the next step would be to call a HVAC technician.

• Ball Bearings. Over time, your furnaces' ball bearings can wear out, and they will require replacement. If you hear a scraping noise coming from your heater, turn it off, and call your local and trusted technicians.

• Noises coming from your heater. If you are hearing a pinging, popping, or even a rattling noise coming from your heater, these noises could be caused by quite a few different issues.
