Though there is simple troubleshooting the furnace homeowners are more than capable of doing, there are some repairs that are best left to the trained professionals. There are a few furnace repairs homeowners can do and others that should be left to the professionals, that we at Hal Mechanical would like to share to help you navigate this territory.
How to Troubleshoot Common Furnace Problems
Circuit breaker. The circuit breaker tripping can be the result of the HVAC system issues. Find the switch for the furnace at the circuit breaker. Should it be flipped, ensure to switch it to the “off” position before restoring the switch to the “on” position.
Air filter. A furnace’s biggest cause to problems is an air filter that is clogged. The clogged air filter is most likely to blame in the event the furnace turns on but doesn’t blow hot air very long. The furnace can shutoff when the airflow through the system is reduced by dirt buildup. First inspect the air filters whenever the furnace demonstrates inefficiency. Clean or change them according to the type of filter if they are full.
Thermostat. Take a peek at the furnace, if the air filters are in good standing or changing them doesn’t improve the furnace’s performance. The furnace may have had an incident that altered the settings, or a dead battery may be the issue. Ensure the desired temperature and it is set to “heat”, rather than “air” or “off” at the furnace.
Professional Furnace Fixes & Repairs
Ignition: Standing pilot lights are no longer equipped, usually. Instead, modern gas furnaces either intermittent pilot or hot surface ignition to start. To keep the furnace ready to start, these modern furnaces are for more efficient without them not constantly burning a small amount of gas. Electricity runs through the igniter and heats it up when the furnace is activated by the thermostat. As they eventually wear down over time, the igniter is a thin piece of metal, much like a standard light bulb. Normal wear is not the only problems ignitions face; however, the other concerns can occur, even risky predicaments. A professional can safely and efficiently repair the furnace if the furnace needs repair beyond the filters and thermostat adjustments.
Belt and/or Blower: With the blower issues, the problem severity can vary, it can simply be due to the belt, however. Because the of the blower belt or the blower itself, the high-pitched sounds stemming from the furnace can occur. Call a professional for proper diagnosis and repair when you hear the high-pitched sounds.
Burner: The air ducts carry the heated air the furnace produces with the reliance of the burner to deliver warm air throughout the home. Despite the efficient operation of the ignition system, and in other instances the burner may not light at all, the burner may not light. You need to make certain to let the pros take care of the issue since this calls for internal assessments and repairs by certified professional.
