Should I Repair or Replace My Faulty Furnace


Your furnace plays a huge role in your home, and it is important to ensure it is always in good condition. So many people keep forgetting about this crucial system until it begins misbehaving during the cold season. However, regular inspections and repairs are the best way to prevent a complete breakdown. Nevertheless, if you already have problems with your furnace, our experts have compiled some guidelines to help you know whether to call for repairs or purchase a new one. Even if the costs are high, your comfort and health should always be the priority.



Most furnaces have a lifespan of between 15 to 30 years. Therefore, if your furnace is under 15 years, our team can do quality repairs and keep it running for many more years. However, if you have a stove that is over twenty years old, it may be better to opt for a replacement. As the years continue, the system weakens and develops multiple problems leading to frequent expensive repairs. Therefore, it would be best to get a new one that will serve you efficiently for the next decades.


Carbon Monoxide

This killer gas can significantly affect the health of the home’s residents and pollute the environment. You can know if your furnace produces this gas by a yellow flame on the burner, signs of soot around the stove, and constant body illnesses. Since carbon monoxide is odorless and tasteless, it is best to look for these signs of trouble to avoid exposure to it over a long time. Carbon monoxide production is a sign of a leak in the combustion chamber, and you need to get your home a new furnace.



At Gervais Mechanical Service, we advise our clients that if they notice that the repair costs exceed half the purchase cost, they should buy a new furnace. Such high costs show that the unit has extensive damage, and repairs won’t completely address the issue.

Higher energy bills usually indicate that the unit consumes much more energy to do the regular heating. Therefore, it is best to consult our team to help you fix the problem as soon as you can.



Whether to repair or replace your furnace is a question you can deliberate with our team. Prompt repairs and maintenance checks also help your unit to function for its entire lifespan with minimal problems. However, it is best to replace it once it begins aging to avoid high repair costs.
