With the average cost of having a new residential furnace around $5,000, it's understandable that homeowners want to get the longest lifespan out of their old furnaces as possible before they "bite the bullet" and pay for a new one. However, continuing to use a furnace that's past the point of needing to be replaced can not only lead to wasted money on higher energy bills, but could even be a safety hazard to those in the home. By being aware of a few telltale signs that it's time for a new furnace, you can determine when the time is right to start shopping around.
Your Burner Flame is Yellow
One of the most telltale signs that it's time for a new furnace is when your gas furnace's burner flame is a yellow color instead of blue. Often, this is a sign that your furnace is producing too much carbon dioxide, which is an odorless and colorless gas that can be fatal in large amounts. A yellow flame doesn't always indicate carbon monoxide buildup, so it's best to check with an HVAC professional, but it's certainly not something you should overlook.
Your Bills Inexplicably Increased
Most homeowners have a pretty good idea of what to expect in terms of their annual heating costs. Therefore, if you've recently noticed a sudden increase in your heating bills and have no explanation for the increase in cost, then your furnace could be on its last legs. After all, those extra monthly heating costs can really add up; ultimately, it'll make more financial sense to upgrade to a new and more energy-efficient furnace that'll have the opposite effect on your energy bills by lowering them.
You Need Repairs Year After Year
There comes a point when the money you spend to keep your older furnace operating simply isn't worth it anymore. It's similar to putting money into an older car. Eventually, you will have spent so much money on repairs that it'll make more sense to simply upgrade to a new furnace. So if it seems like you need to have repairs done on your furnace year after year, it might be time to consider a new furnace altogether.
These are just a few common signs that it's time for a new furnace at your home. If you're thinking about having your existing furnace replaced, start by finding a qualified and experienced HVAC contractor, such as Quality HomEnergy.
