Signs It’s Time for a New Furnace


As the winter months approach, a reliable heating system becomes a necessity. One of the most important pieces of equipment in your HVAC system is the furnace. It’s responsible for keeping your home warm and comfortable, but like any other appliance, it has a lifespan. So, how do you know when it’s time for a new furnace? In this blog post, we’ll discuss some of the signs that indicate it’s time for a replacement. Whether you’re a homeowner or a renter, this information will help you make informed decisions about your home’s heating system.


1. Age of the Furnace

The average lifespan of a furnace is approximately 15-20 years. After this time, your furnace is likely to lose efficiency, become more prone to breakdowns, and require costly repairs. Therefore, if your furnace is reaching this age, it’s time to start thinking about a replacement. However, even if your furnace is newer than 15 years, you should consider upgrading to a newer, more energy-efficient model to save money on your energy bills.

2. Increased Energy Bills

If your energy bills have been consistently increasing, and your usage habits haven’t changed, then it could be due to an inefficient furnace. An older furnace will have to work harder to provide the same level of heat as a newer model. As a result, it will use more energy, leading to higher energy bills. A newer, more efficient furnace, on the other hand, will use less energy to do the same job, leading to lower energy bills.

3. Frequent Breakdowns

Frequent breakdowns are a clear sign that your furnace is in bad shape. If you’re constantly calling in repair technicians to fix your furnace, you may be throwing good money after bad. Instead, it might be time to invest in a new, reliable furnace that won’t let you down. While a furnace replacement may require a significant investment upfront, it will save you money in the long run by reducing repair costs and increasing energy efficiency.

4. Noisy Furnace

A furnace that makes unusual noises is likely nearing the end of its lifespan. Banging, clanking, or rattling noises may indicate that parts of your furnace are loose or damaged. In some cases, these issues can be fixed with a repair. However, if the problems persist, it may be time to replace your furnace. A new, modern furnace will operate quietly and efficiently, providing you with peace of mind and comfort.

5. Uncomfortable Home

If your home is uncomfortable, despite your furnace working properly, it may be time for an upgrade. An older furnace will struggle to keep up with your home’s heating demands, leading to inconsistent temperatures and discomfort. A new, energy-efficient furnace, on the other hand, will be better equipped to handle the challenges of modern living spaces, providing you with a more comfortable home and even heating.
