The furnace is crucial in warming your home during the cold season. To ensure your furnace works efficiently, you should know how to tell when to repair or replace it. Here are some ways to determine the appropriate remedy for a faulty furnace.

The Cost of Repairs

The average furnace costs between $2,000 and $6,200 based on the type and efficiency level. Replacement prices vary depending on brand, warranties, and location. You should compare the costs when determining whether to replace or repair your furnace. If repair costs are more than 50% of the cost of a replacement, you should replace the unit. 

The Age of the Furnace

The average furnace has a life expectancy of 15 to 20 years. When choosing between repairing or replacing, consider the age of the furnace. As a rule of thumb, it is more reasonable to replace an old system. This is because repairing an issue on an old furnace is a temporary fix, and you can expect to spend more on repairs in the future.

Loud and Violent Noises

Popping and rattling noises could be signs of an overheating furnace. This causes metal to grind or expand against objects inside. If your system is still new and you hear these noises, cleaning and replacing filters may resolve the problem.

Another reason for these noises could be damaged or loose ductwork. Therefore, a vent insulation cover may address the issue. However, if it's an old system, the cause of these noises could be worn-out internal components. The solution, in this case, would be to replace the system.

High Energy Bills

The cost of heating fluctuates because of changes in weather patterns. You will pay higher energy bills during cold weather than in warm seasons. However, you should be keen on unusual spikes that coincide with your furnace use.

Compare the cost of electricity from the recent heating season with the bills from previous seasons. If there is a significant difference, your furnace is using up too much energy. One reason could be that it works harder than usual to warm your home. Replacing the filter could resolve the problem. If this doesn't work, you might have to replace the furnace.

In Closing

Regular furnace maintenance is one of the best ways to keep your furnace working efficiently. However, some furnace problems arise with continued usage or age and can only be addressed through repairs or a replacement. If you notice your furnace behaving awkwardly, make sure you consult a technician to help you determine whether to repair or replace it.
