5 Reasons Why Big Bear Furnace Repair Might Be Necessary

Bear Valley Plumbing & Heating


When was the last time you thought about your home furnace? Are you sure that a furnace repair is not in order?

If you are like most people, you do not think about your furnace until you turn it on at the start of winter or until it malfunctions. After all, your furnace is out of sight so it is out of mind. However, furnaces are not infallible, and can directly affect the heat and air quality in your home. It is only a matter of time until this complex machine breaks down. Below, we shed light on some of the top reasons why furnace repair is necessary for due time.

1. A Clogged or Dirty Furnace Filter is a Significant Problem in Big Bear, CA

Your furnace’s filter will gradually collect dirt and other particles as time progresses. Though collecting such particles is the purpose of the filter, it will gradually wear out as time progresses. If the air filter in your furnace becomes excessively clogged, it will force the furnace to work that much harder to heat your living space to your selected temperature. This additional work is likely to cause the furnace to a malfunction or wear out that much sooner. This is precisely why your furnace’s air filter should be replaced as soon as it accumulates a substantial amount of dirt or other gunk.

There is no harm in checking your furnace’s air filter once every month or two just to make sure it is not overloaded with dirt and other particles. Replace the dirty furnace filter when necessary and your furnace will function to the best of its ability. However, if you neglect the furnace filter, its gunk and grime will eventually cause problems with the unit that spur the need for furnace repair. When in doubt, lean on our professional HVAC gurus in Big Bear, CA for assistance. We will gladly inspect your furnace, identify areas for improvement/repair and ensure your home remains comfortable throughout the entirety of the year.

2. Overheating of the Furnace

Furnaces are designed to generate heat yet these machines have the potential to overheat. Even something as seemingly minor as a clogged filter has the potential to cause a furnace to overheat. Dirt, dust and other grime obstruct the flow of air, forcing the furnace to work that much harder and run longer than should be necessary to warm your living space to the appropriate temperature. If you suspect or know your furnace has overheated, do not overlook the problem. Repeated overheating compromises the heat exchanger. This essential furnace component has the potential to prove quite costly to replace or repair.

3. A Faulty Thermostat

Plenty of home heating problems are attributable to a malfunctioning thermostat. However, most people assume it is the furnace itself that is the problem, failing to even consider there might be something wrong with the thermostat. Take a close look at the thermostat to ensure it is set to “heat” as opposed to “off” or “cool”. Furthermore, the fans should be on the “Auto” setting. In some cases, the thermostat simply needs new batteries. However, there is a chance your home thermostat is not functioning as it should. From old age to an influx of dust/dirt and beyond, all sorts of problems can cause the thermostat to display an inaccurate temperature reading or simply fail to function as it should. Our Big Bear HVAC professionals are here to troubleshoot your thermostat and furnace, determine the true cause of the problem and perform the necessary repair(s).

4. Insufficient Maintenance Leading to Poor Heat and Air Quality

Yearly maintenance is essential to ensuring your home heating system functions exactly as it should. Fail to have your furnace maintained every year and you dramatically increase the chances of a subsequent repair. A routine furnace inspection ensures no repairs or replacement are necessary. Even if our Big Bear HVAC crew’s inspection of your furnace indicates a minor repair is necessary, it is worth paying this comparably small expense rather than waiting until an even more costly problem arises. The alternative is to neglect your furnace and hope it functions as designed. Spend the little bit of money necessary for furnace maintenance and you just might prevent a budget-busting repair or replacement down the line.

5. Fuel Supply Issues

Fuel supply problems have the potential to spur the need for furnace repairs. Regardless of whether your furnace is powered by electricity or natural gas, a fuel supply issue has the potential to cause the system to fail. Electric furnaces sometimes fail as a result of poor wiring. Faulty wiring eventually leads to a short and breaker blowing. If your furnace has such a problem, reach out to our savvy Big Bear furnace repair crew right away for prompt assistance. Alternatively, if your furnace operates on natural gas and you suspect or know there is a fuel supply issue, contact us right away to prevent potential poisoning. After all, natural gas is toxic when inhaled so it is better to be safe rather than sorry by asking our professionals for assistance.

Final Thought

A well-maintained furnace goes a long way in keeping your home warm, and you feel comfortable. It is necessary to ensure that it isn’t neglected and used properly. The above points should enlighten you about the common reasons why your furnace might need attention. Getting HVAC professionals on the job is a great idea if you’re looking for long-term, yet affordable solutions.
