Furnace Replacement or Repair?
Unless your furnace is inoperable, the question of whether to replace your furnace now or continue to repair it for a while depends on a variety of factors:
Age: In general, a well-maintained furnace has a life span of 15 to 20 years. However, a neglected furnace may need replacing after just 10 years or less. If your furnace still has a few good years left, and the energy and repair bills aren’t piling up, you can hold onto your existing furnace a little longer.
Repair history: Once your furnace starts needing frequent repairs, it may be a signal it’s on its last legs. An experienced HVAC technician can help you evaluate the condition of your furnace and weigh the potential future repair costs against the price of a new furnace replacement to determine which route is more economical in the short-term and the long-term.
Home comfort: If your furnace isn’t doing a good job of keeping you comfortable, and repairs haven’t solved the problem, it may be time for a new system. This is true whether the heat output is inadequate across the house or one or more rooms are consistently colder than the others.
Once you decide it’s time for a furnace replacement, your friendly local HVAC contractor can help you choose a new system.
Here are the most important factors to consider when buying a new furnace:
- Your preferred fuel type (electricity or gas)
- The energy efficiency of the system, measured by the Annual Fuel Utilization Efficiency (AFUE), with higher percentages indicating a more fuel-efficient system
- Heating capacity and size
- Ductwork compatibility
- Advanced features, such as zoning capabilities or smart home integration
- Brand reputation
- Government rebates and incentives that might lower the cost of a new furnace installation
Once your new furnace is installed, regular seasonal maintenance will help keep it operating efficiently year after year for the duration of its life span.
Regular maintenance in the early fall involves cleaning your system, tightening belts and connections, lubricating the motor and other moving parts, and testing the controls of the system, among other essential tasks.
