5 Signs it’s Time to Replace Your Old Furnace

5 Signs it's Time to Replace Your Old Furnace

When winter rolls in, keeping your home warm and comfortable quickly becomes the top priority.

However, if your furnace is older, you may find it difficult to maintain comfortable temperatures inside your house.

At Canadian Clean Air Services, our experienced staff wants to help, whether your old furnace needs repairing or you need a full system replacement.

Here are a few signs it’s time to replace your aging unit.

You've Noticed an Increase in Your Heating Costs

Heating systems are designed to keep your home comfortable as efficiently as possible and, while a slight increase in energy costs should be expected, it shouldn’t be extreme.

If you notice that your heating costs are higher than they were the previous year, it could indicate that your furnace is due for a replacement.

Remember, newer units are designed to use less energy than old boilers, and the savings on your energy bills may be enough to offset the cost of installing a new unit.

Repairs are Almost Constant

While it’s possible to keep an old furnace running for years, it’s not always the best option.

If you’re calling your repair technician every month or so to fix a new problem, it may be best to install a new furnace.

The last thing you want is for your furnace to break right when a blizzard rolls in.

Scheduling a boiler and furnace installation before winter is in full swing will help you reduce the risk of going without heat.

The System is Over 15 Years Old

Like any major appliance, your furnace and home heating system will eventually need to be replaced.

Most units, with regular care and maintenance, last around 15 years. If you’ve had the same system running or can’t remember the last time you scheduled a boiler and furnace installation, it’s likely time to upgrade.

At Canadian Clean Air Systems, we’ll inspect your old boiler for signs of age and wear and advise you on the best solution for your home according to your needs.

Strange Noises are Coming From the Furnace

Most furnaces make some degree of noise when they turn on. However, if you hear loud clanking, banging, or rattling coming from your furnace, it may be time for a replacement.

These noises often indicate that the pressure inside the unit is no longer at optimal levels, impacting the overall performance of your home heating system.

You Smell Gas Around the Furnace

Gas is a reliable fuel source for home heat systems, but it’s not without its hazards.

If you smell gas around your furnace, it’s likely that you have a slow leak somewhere in the system.

Keep in mind that even a small leak is incredibly dangerous and should be addressed by an experienced technician as soon as possible.

However, old furnaces often cannot be repaired completely and it’s best to simply schedule a new furnace installation to upgrade your home’s heating system.


If you’re concerned about the condition of your heating system or are ready to upgrade from your old boiler to a new furnace installation with our technicians, don’t wait any longer.
