While the ultimate sign your furnace needs repair is when it breaks down completely and refuses to run, there are several signs a breakdown might be coming and your furnace should be evaluated by a professional. Here are four of the most common signs your furnace needs repair:

Weird smells: Unusual odors, such as burning or musty smells, can be signs of issues with your furnace. These smells may be caused by a variety of problems, including dust buildup, gas leaks or even electrical issues. It is important to address these smells promptly for safety reasons.

Difficulty starting your furnace: If you have trouble starting your furnace or if it takes longer than usual to turn on, it could indicate a malfunctioning ignition system, faulty wiring or another mechanical issues. If this is the case, it’s a good idea to call a professional for furnace maintenance or repair.

Uneven heating: If some areas of your home are much colder than others, it may signify a problem with your furnace’s distribution system. A professional technician can diagnose and fix the problem.

Increase in energy bills: A sudden and significant increase in your energy bills without any changes in usage patterns can indicate that your furnace is not operating efficiently. When your heating system experiences a sudden loss of efficiency, it could be a sign of repair or that your unit is failing, and you may need to start saving for furnace replacement.

Should I Keep Repairing My Old Furnace or Replace It?

Furnaces tend to become more unreliable as they age. However, it’s often difficult to know if you should keep paying for HVAC repair for your heating system or instead invest in furnace replacement. After all, while you don’t want to give up on your old furnace prematurely—you also don’t want to waste money repairing a failing unit.

Fortunately, there are a few guidelines to help you make that decision:

The age of your furnace is an important factor to consider. Most furnaces have a lifespan of around 10-15 years. If your furnace is approaching or has exceeded this range, it may be more cost-effective to replace it rather than investing in frequent repairs.

Repair costs versus replacement costs
Compare the cost of repairing your old furnace with the cost of installing a new heating system. If the repair costs are frequent, significantly high and approaches or exceeds 50% of the cost of a new furnace, it may be more economical to replace the system instead.

Safety concerns

Safety should always be a top priority. If your old furnace poses safety risks, such as carbon monoxide leaks, cracks in the heat exchanger or unreliable operation that could leave you in the cold, it is critical to prioritize the safety of your household and consider replacing the unit.

Energy efficiency
Older furnaces tend to be less energy-efficient compared to newer models. That means they use more energy—and cost more to run—to produce the heat to keep you and your family warm. Consider the potential energy savings you could achieve with a new, more efficient furnace. Over time, these savings can offset the initial investment of a replacement.

Great job by all. They were careful of the landscape replacing the A/C unit. Inside the heating system was replaced and the fit and finish was great. Explained the operation of everything. They came back two weeks later and checked out the operation of the systems plus installation. The tech was here over an hour checking out everything. New system is quiet. This is a company that care about its customer. We highly recommend A-1.
