If your furnace has been less than reliable lately, you may be wondering if it’s time to replace your unit and start over with something new. While some signs that your furnace needs to be replaced are very clear, other underlying signs can be a bit more mysterious.

If you notice one or more of these signs that your unit needs a replacement, it’s probably time to bite the bullet and install a new, more reliable furnace.

Frequent Furnace Repairs

Do you feel like you’re constantly dealing with a broken-down furnace? This is never a good sign. Although furnaces do need regular checkups and maintenance, your furnace should be pretty reliable on the whole. If you find yourself doing furnace repairs more often than normal, it is probably time to call a professional and install a new unit.

Rising or High Energy Bills

If you’ve noticed that your energy bills seem inexplicably high or higher than they have been in the past, it’s quite likely that your furnace isn’t acting as efficiently anymore. Call a professional to see if your furnace can be fixed with a simple repair, or if it’s more serious and a new furnace needs to be installed to save your hard-earned money.

Unusual Noises

Old furnaces often make some noise, but they shouldn’t be very loud or intrusive. If you’re noticing that your furnace is making new and unpleasant noises, it’s possible that it just needs a quick tune-up. If a furnace repair doesn’t fit the problem, though, that may mean it’s time to buy a new furnace altogether.

Rusty Components While Doing a Furnace Repair


If your furnace looks visibly rusty or ready to fall apart, it’s definitely time to replace it. Rust can negatively affect important components of your unit and stop it from heating your home properly. Rust is a sign that buying a new furnace is in order.

Visible Cracks After a Furnace Repair

Cracks in your furnace can allow air to escape from your unit and, in turn, make your furnace less efficient. Visible cracks in your furnace are a telltale sign that you need to call a professional to get a new furnace installed.

A Simple Furnace Repair Doesn’t Fix Unevenly Heated Rooms

Are some of your rooms getting more heat than others? This could be caused by a thermostat issue, but if a simple repair job doesn’t solve the problem, your furnace is probably faulty.

New Home Humidity Problems

Excess humidity in the home can be a frustrating problem that leads to dangerous mold around the house, and it can also be a sign of a broken furnace. If you’re experiencing new home humidity problems and furnace repair or maintenance doesn’t reduce them, consider calling a professional to talk about replacing your unit.

Excess Dust Around Your Furnace

If you’ve noticed that there is an unusual amount of dust around your furnace, it’s a good idea to check that your air filters aren’t clogged and you don’t have faulty ductwork. If neither of those issues is causing the problem, you probably need a new furnace.

An Old Furnace

One of the easiest ways to know if it’s time to replace your furnace is by its age. If you are experiencing any of these problems and your furnace is over 15 years old, it’s time to take the plunge and replace your unit.
