6 Signs It’s Time for a Furnace Replacement

November 12th, 2021 | Around The Home, Heating & Cooling

With winter approaching, you’re probably getting your home ready in all kinds of ways. Homeowners in Memphis, TN, and worldwide are running through their checklists this time of year, making sure everything is set for harsh winter conditions.

While there is much to do, one of your top priorities should be evaluating your furnace. Replacing your furnace might be in your future if you notice some warning signs. 

Signs You May Need a New Furnace

It’s hard to decide whether you need a furnace replacement. If things are still working, why would you make a change? But even if your heater is still warming your home, that doesn’t mean you can rely on it forever.

You have several options for a new furnace, including gas, oil, and electric. Gas is typically the least expensive to operate, as oil and electric resources have higher energy costs. 

Electric options are also very desirable and typically cost less upfront. Oil can also be a great choice if you want to heat a smaller space or if your home doesn’t have easy access to a gas line. 

Whatever choice you make, a new furnace can be an amazing upgrade to your home. Still, you need to know what to watch for when deciding if you need a new heating system. Here are six signs it may be time to replace your furnace:

1. Your Furnace is Old

All furnaces have an average lifespan, and if yours is getting up there in age, it may be time to consider a furnace replacement. A gas furnace typically lasts about 15 to 20 years, so if yours is over 15 years old, you’ll want to watch it closely for other warning signs. 

2. Your Energy Bill is Going Up

Another telltale sign it’s time to replace your furnace is an unexplained increase in your energy bill. If there’s no other reason for the increase, it’s time to look at your furnace. Older heaters need to work harder to produce the same amount of heat so they can be a drain on your energy. 

If your bill has gone up since previous years without another explanation, this can be a strong sign it’s time for a furnace replacement. 

3. Recurring Repairs

All furnaces require regular maintenance, and it’s not uncommon to need a furnace tune-up, especially if your system is over ten years old. Still, if you’ve noticed a frequent need for heating repairs, it could be a sign it’s time to replace your furnace. 

Heating repair costs can add up over time, and it’s likely your heater is working harder than necessary to keep your home warm. You could probably save money on your monthly bills with an upgrade, and a new furnace can ensure things will keep working properly.

4. Strange Noises

Hearing an odd noise come from any piece of equipment is never a good sign. If your furnace starts making ratting, screeching, or humming noises, it could be cause for concern. 

Have a technician evaluate your furnace to see if they suggest a repair or a furnace replacement. In particular, a booming sound could mean ignition issues, which can be a safety concern.

5. Visible Issues

If there are visible structural issues with your furnace, this can mean it’s time for a replacement. Cracks or rust should be taken seriously, as they can indicate problems that can pose safety concerns. Inspect your heater looking for imperfections, and make sure to reach out to a technician for an evaluation if you see any. 

6. A Yellow Flame

Your furnace’s flame should be blue if it’s working properly. If it’s any other color, that’s a strong sign it might be time for a furnace replacement. In particular, a yellow flame can mean your furnace emits carbon monoxide, a poisonous gas. 

If you notice a yellow flame in your furnace, you should have an expert look at it immediately. Also, make sure you take steps such as improved ventilation to ensure the safety of everyone in your home. 

How to Maintain Your Furnace

To keep your furnace in top condition, you’ll want to have an HVAC contractor perform regular, yearly inspections. When you properly care for your furnace, you’ll help it last through its full lifespan and maintain proper output. 

Here are some of the things a technician will do when they service your furnace:

  • Examine the pilot light and all wiring
  • Note performance and mechanical problems
  • Clean the pilot light and fuel line
  • Calibrate the pressure in the fuel line 
  • Provide lubrication for moving parts

Like any other machinery or equipment in your home, furnaces require regular maintenance to maintain optimum performance and lifespan. So if you’re getting ready for the colder winter months in Memphis, TN, or anywhere else, it’s important to schedule regular yearly inspections with a trusted technician.
