Faulty Furnace Can Lead To High Heating Bills

December 29, 2025

With the weather getting colder you will require more heat to keep your home at a comfortable temperature. This does not mean your heating bill needs to skyrocket. As a responsible homeowner you will be looking over your monthly bills to stay within budget. If you notice your bills rising without any substantial change from the previous winter, it could be a result of a few factors including a faulty furnace. Below we discuss what can lead to high utility bills and what you can do to lower them while still staying warm in your home in Simi Valley.

Inefficient Furnace

Your furnace must be inspected on a routine basis. Routine maintenance helps ensure your furnace operates properly and efficiently in Simi Valley. An efficient furnace will help keep your heating bills low. Furthermore, routine maintenance helps the system reach its full lifespan of at least 10-15 years, with some as many as 25 years. Maintenance can also help minimize the severity and cost of repairs, by catching issues early on before they become catastrophic.

When you have your furnace inspected it is also a good time to check the batteries in your smoke alarms and carbon monoxide detectors. A trained professional HVAC technician will be able to spot any potential hazards that may endanger the inhabitants of your home by catching any existing or developing issues that could lead to carbon monoxide in your home. They will also be able to see if there is any debris or dust buildup that could not only have a negative impact on your system, but your indoor air quality as well.

Poor Insulation

If you live in an older home or there is lack of insulation in attic and walls, you could be losing heat through leaky windows and doors which could also lead to higher than usual heating bills. If you notice the furnace is running long periods of time without your home getting any warmer, it could be a sign of poor insulation.

You may need to add weather stripping around doors and upgrade your windows, as well as checking the condition of the insulation in your attic. This will help lower the costs of heating and cooling your home and help keep you comfortable year-round.

Leaky Ductwork

Leaks in the ductwork could also increase your monthly heating bills. Contact a professional like LA Construction, Heating and Air to inspect your ductwork and check for any leaks and fix the problem. It is important to remember that leaky ductwork could not only increase your bills, but it impacts your indoor air quality and could clog air filters and damage the HVAC system.

Thermostat Issues

Thermostats can negatively impact the heating needs in your home. Try turning your thermostat down between 8 to 10° F for an 8-hour period which could save you 5% to 10% on your heating costs. Modern programmable and smart thermostats make temperature adjustments easy and manageable even when you are not at home. This way you can program it to only run when you are at home.

Furnace Beyond Repair

While it may be costly to replace a furnace, if you have a furnace past its lifetime with a costly repair it may be time to consider furnace replacement instead. You could replace your furnace with one that has 80 or 96 efficiency which could save you up to 20% on energy. We can help you determine whether it would be better to repair or if it is time for a new furnace now. Not only will a new furnace be more energy efficient, but less fuel used means it will also be more environmentally friendlier than older models.
