During the long, cold winters days, a reliable furnace is the best way to keep your home nice and warm. It's important to provide regular maintenance checks on the appliance. This keeps the furnace functioning properly and can extend the life expectancy.
However, even the best-serviced furnace can stop working due to a number of reasons. Some of them you can troubleshoot, while other causes lead to replacing the entire unit. Use this guide to find out which type of issue you have and if it is a reason for concern.
The age of the furnace could be the reason that it is not working properly, if at all. The life expectancy of the unit will vary depending on many factors, like the brand or if it is gas or electric. Most furnaces last an average of 15 to 20 years. If your furnace is in this age range, then you should replace it with a newer model. You may find that the newer models are more energy-efficient and run better than the old one did.
The thermostat for the furnace controls the temperature setting. Thermostats are usually digital or spin dials. If the furnace isn't kicking on as it should, try adjusting the thermostat a few degrees. The heat should turn on if everything is working correctly. If it doesn't, you might need a new thermostat.
Another reason that the furnace doesn't turn on is a lack of power. The most common cause is a tripped breaker. Find the breaker box in your home. It is usually located in the basement of residential properties. There will be a lot of breakers, and they will be labeled. Find the one marked Furnance. If it is in the Off position, flip it back to On. This should fix the issue. Note: if the breaker keeps tripping, you should have a professional check it out since this points to a major problem.
The filter in the furnace needs to be cleaned on a regular basis. It collects dust each day while the furnace is running. Over time, it is completely covered and cannot work properly. This can hinder the entire appliance if it is not taken care of. It will also produce insufficient air supply for the appliance. Remove the filter and rub it down thoroughly with a damp rag. Some models may not be reusable and will need to be replaced when they are dirty.
Any serious issues with your furnace should be dealt with by an HVAC contractor. They have the expertise to diagnose any problems and can fix or replace your unit. Contact a furnace repair service for more information.Share
