Understanding When It's Time To Plan For Furnace Replacement

Posted on

At some point, a furnace becomes old enough that continuing to repair it is inadvisable. Contractors who install and service residential heating systems let customers know when they should start preparing for replacement. This gives homeowners a year or two to decide how to pay for the new equipment and all required labor.


When a furnace repeatedly breaks down during heating seasons even after annual maintenance has been performed, the appliance is wearing out. Technicians also can see when the air exchanger has developed enough wear and tear that furnace replacement should be completed in the near future.


Since this is one of the more expensive home improvement projects, some people try to wait as long as possible before scheduling a replacement. Homeowners generally can expect furnaces to operate safely for about 15 years, though that varies a great deal depending on certain factors.

People living in milder climates don't use a heating system as frequently. Some brands and models tend to have longer lifespans. Higher-efficiency versions usually last longer because they do not work as hard to keep the home warm. In addition, people who schedule annual maintenance on the furnace and change the air filter according to instructions allow the equipment to operate with less effort.

Time Frame

It's imperative not to delay too long once a trusted service technician recommends replacement. A cracked air exchanger is a significant safety hazard, as it leaks toxic carbon monoxide into the home. 

Advantages of a New Furnace

Customers of a residential heating service will want to focus on the benefits they achieve with a new furnace.

Efficiency will be higher, keeping utility costs lower. Two reasons account for this. First, manufacturers have improved efficiency over the years. Second, older equipment loses efficiency over time. As the years pass, the furnace requires more gas to maintain the thermostat temperature.

As long as the homeowners schedule yearly maintenance as recommended, the furnace should not develop problems for many years. Household residents know the appliance won't break down on a cold winter night. They don't have to worry about the possibility of needing emergency repair service. Late-night and weekend service calls are inconvenient for the household and may cost more as well. 

Concluding Thoughts

The eventual need for a new furnace is inevitable since no major appliance lasts forever. When the equipment nears the end of its useful and safe lifespan, planning for a new installation is advisable.
