Forced air furnaces are popular choices for heating homes across the United States. A forced air furnace works by distributing heated air throughout your home via vents and air ducts. Unfortunately, as your forced air furnace ages, it can begin to become less effective and require repair work. The good news is, your forced air furnace will give you plenty of warning signs to let you know that something is awry. There are two basic types of forced air furnaces, conventional gas furnaces with pilot lights that vent exhaust fumes through chimneys (found in older homes) and high efficiency furnaces. Regardless of the type of furnace in your home, both are designed to take in cold air, clean the air with an air filter, heat the air, and distribute the heated air through the ductwork. Air Supply Heating & Air Conditioning presents common problems with conventional gas furnaces.
Not Enough or No Heat
With the cold weather fast approaching, you want the reassurance of knowing that your furnace is working correctly and producing the right amount of heat required to keep your home warm and toasty during the winter months. If your furnace is blowing cool air, there are a couple of things you can do before calling the professionals at Air Supply Heating & Air Conditioning. Begin by checking to ensure that your heat registers are open, your thermostat settings are set correctly, and your furnace has power.
Furnace Turns On & Off Frequently
in extreme temperatures, your gas furnace may cycle on and off to keep your home warm. If your furnace is cycling on and off, otherwise known as short cycling, it could be something as simple as a dirty filter or a more advanced problem like a faulty thermostat.
Furnace Blower Running Continuously
If the blower in your furnace runs continuously, it is most likely because your thermostat is set on the fan setting and can be easily rectified by changing the blower setting on the thermostat back to the Auto position. Adjusting the thermostat back to auto will ensure that your fan will only run when heating or cooling the air.
Excessive Noise from Heating System
Any noise coming from your furnace should be taken seriously and has the potential to turn into a costly repair bill if ignored. Contact the experts at Air Supply Heating & Air Conditioning to schedule your inspection and repairs before the frigid cold arrives
Electronic Ignition Problems
If your electronic ignition is malfunctioning, your furnace will not be able to produce the heat needed to warm your home adequately. The first thing you can do is replace the filter and check the power and gas line attached to your furnace to ensure they are not broken and in proper working order.
Bad Furnace Thermostat
Your furnace & thermostat must be compatible; otherwise, it will cause operating problems, including overheating or underheating the air regardless of what is set on the thermostat. The three most popular types of thermostats used in high-efficiency furnaces include millivolt, low voltage, and line voltage. Make sure you have the correct kind installed on your furnace. Iissues with your thermostat can cause numerous problems, including temperature fluctuations, frequent cycling on and off, or your thermostat may not be producing any heat at all. Check the components to make sure they are not dusty or filled with debris. If the problem persists, contact the experts at Air Supply Heating & Air Conditioning to schedule an inspection.
