There’s no secret that, to generate the heat that warms your home, a furnace or heat pump relies on fuel of some sort. Whether your furnace or heat pump burns natural gas, propane, or oil, it still must burn something to generate heat that can be disseminated around your home. Fuel for your heat pump represents a significant recurring cost that can spike in the coldest months of the year. Those costs can increase even more when your heat pump isn’t as efficient as it should be or when it consumes too much fuel to generate the desired effect.

Sometimes, you may not know that your furnace isn’t running efficiently until you get that first exorbitant energy bill of the winter. If you suspect that your furnace or heat pump may be burning too much fuel, your first step should be to contact a heating repair service to have your heat pump inspected by a professional. Failure to repair an inefficient furnace or heat pump goes beyond mere inconvenience and higher energy bills. It can result in damage to your furnace that may require professional repair or new heating installation in Gainesville, GA. It’s important to understand what factors can cause your gas to overconsume fuel, since some can be remedied easily by a homeowner. Read on to learn more about the reasons that your heat pump may be overconsuming fuel.

Dirty Filters

The filters on your HVAC system play a critical role in protecting both your system and your health. Changing the filters regularly is so simple that any homeowner can do it, but it’s also one of the most important preventive maintenance steps that must be taken to protect your unit. When you run your furnace or heat pump with a dirty filter, it can impact the overall efficiency of your system and hurt performance significantly. When your furnace or heat pump doesn’t run efficiently, it must burn more fuel to attain the same level of performance as an optimized system. Therefore, changing your filters regularly will keep fuel usage to a minimum.

Continuously Lit Pilots

While most newer furnace feature electronic pilots that light only when the furnace or heat pump is being used, older models have continuous pilots that remain lit all the time. They stay lit by burning a tiny amount of the same fuel used by the heat pump. If your heat pump has a continuously lit pilot, then that can result in constant fuel usage. There’s not a lot your can do to mitigate that dynamic, however, aside from installing a new furnace unit with an electronic pilot.

Poor Insulation

Your heat pump will use more fuel as the efficiency of your HVAC system is reduced. One factor that can impact the performance of your heating system is improper insulation or drafts that rob your home of heat and make temperature maintenance more difficult for your system. If you suspect your heat pump is using too much fuel, it may have something to do with poor insulation, drafts, and heat loss.

Leaky Ducts

The ducts in your HVAC system are important because they carry the warm air from your heat pump to every corner of your home. However, when those ducts are damaged or worn, they can compromise the efficiency of your heat pump and result in excessive fuel consumption. Not only will warm air leak out into unused attic spaces, but leaky ducts also allow cold attic air to infiltrate your ducts and blend with the air that your heat pump worked hard to warm.

If you fear that your furnace or heat pump is burning too much fuel, identify the potential sources of inefficiency and attempt to correct them. Some tasks, such as changing the air filter, can be accomplished without professional assistance. However, other causes of inefficiency are best remedied by an HVAC service.
