There are a number of furnace complications that are quite common that the homeowner can remedy and others that should be left to a professional. To help you navigate this territory, we at Air Supply Air Conditioning & Heating would like to share a few furnace rectifications homeowners can do and others that should be left to the professionals.
DIY Furnace Maintenance
Air filter. Air filter clogs are a furnace’s biggest causes to problems. In the event the furnace turns on but doesn’t blow hot air very long, the clogged air filter is most likely to blame. When the airflow through the system is reduced by dirt buildup, the furnace can shutoff. Whenever the furnace demonstrates inefficiency, first inspect the air filters. If they are full, clean or change them according to the type of filter.
Thermostat. If the air filters are in good standing or changing them doesn’t improve the furnace’s performance, check the thermostat. A dead battery may be the issue, or the furnace may have had an incident that altered the settings. Be sure the thermostat is set at the desired temperature and it is set to “heat”, rather than “air” or “off.”
Circuit breaker. There some situations that lead to the circuit breaking tripping. Check the circuit breaker and find the switch for the furnace. If it is flipped, be sure to switch it to the “off” position before restoring the switch to the “on” position.
When to Call for Professional Furnace Repairs
Ignition: No longer usually equipped with standing pilot lights, modern gas furnaces either intermittent pilot or hot surface ignition instead to start. These modern furnaces are for more efficient without them not constantly burning a small amount of gas just to keep the furnace ready to start. The most common modern method is the hot surface ignition system. When the furnace is activated by the thermostat, electricity runs through the igniter and heats it up. The igniter, a thin piece of metal, much like a standard light bulb, eventually wears down over time. The normal wear is not the only issue the ignition faces, but other problems and even hazardous predicaments can manifest. If the furnace needs repair beyond the filters and thermostat adjustments, a professional can safely and efficiently repair the furnace.
Burner: To deliver warm air throughout the home, the air ducts carry the heated air the furnace produces with the reliance of the burner. The burner may not light, despite the efficient operation of the ignition system, and in other instances the burner may not light at all. Where this calls for internal assessments and repairs by certified professional, you need to make certain to let the pros take care of the issue.
Belt and/or Blower: The problem severity can vary with the blower issues; however, it can simply be due to the belt. The high-pitched sounds stemming from the furnace can occur because the of the blower belt or the blower itself. When you hear the high-pitched sounds, call a professional for proper diagnosis and repair.
