Top 5 Signs You Need Your Furnace Serviced

Winter is quickly approaching, and if you haven’t been in the habit of getting your furnace inspected once a year, it’s likely time for a check up.

According to Fox Business,

Furnace manufacturers all recommend annual inspections and maintenance by a qualified technician. They also have language in their warranties saying that damage to the units caused by improper maintenance is not covered under the warranty. 

Does this mean that an annual furnace checkup is really required, or the warranty is voided? Probably not, but it’s recommended. The best analogy is going to the dentist every six months for a checkup and cleaning; probably not necessary, but recommended.

Some HVAC contractors recommend getting newer furnaces checked every other year, but once they’re more than 10 years old, have them checked annually.”

If you’re still on the fence about whether or not you need your furnace serviced this year, here are our top five reasons to schedule a furnace inspection. 

1. Your Furnace Makes Odd Noises

If you’ve ever been awakened by thumps or bangs in the night, this could be an indicator of a serious problem with your HVAC system.

Why does this happen?

Loose mechanical parts, like belts, can cause your heater to malfunction, and can even be dangerous. Grinding, squeaking, or loud bangs can all be signs of a belt issue. 

If your furnace makes any unusual noises, it’s best to get it evaluated by a trained expert as soon as possible.

2. Your Furnace Smells Weird

If you ever detect an odd smell coming from your natural gas or propane furnace, or if you smell gas in your home at all, it’s very possible that your furnace has a gas leakage of some kind.

Why does this happen?

If you smell gas, it’s likely because there’s a leak in your systems heat exchanger. 

The prevention of gas leaks is a reason alone to get your furnace inspected yearly. It’s also wise to install and routinely inspect carbon monoxide detectors – especially once fall and winter approach. 

Gas leaking from your furnace can be dangerous on multiple levels. If left unattended you risk fire hazards, and carbon monoxide poisoning. 

If you smell gas leaking, it’s critical that you address it right away. Immediately shut down your furnace, shut off the gas supply valve, and call a certified HVAC technician. 


3. Your Thermostat Doesn’t Work Properly 

If it seems that your furnace doesn’t kick on when it should anymore – or if it’s turning on when it shouldn’t – you may have an issue with your thermostat, furnace, or both. 

Why does this happen? 

Thermostat issues can happen for a few different reasons. Inaccurate temperature readings, or heat anticipator issues can cause a disconnect between your thermostat and your actual heating system. 

The fix could be as simple as addressing drafts near your thermostat, or replacing a dirty air filter. In any case, a good technician should be able to inspect your thermostat and your furnace, and make adjustments if needed. 


4. Utility Bills Spike

If your utility bills seem much higher than normal, your furnace may be to blame. While the cost of running your furnace from year to year can certainly fluctuate some, keep a close eye out for sudden utility spikes.

Why does this happen?

If your heating bills jump suddenly, you may have failing components such as a thermostat malfunction or leaky air ducts. 

When getting your furnace serviced, a professional should be able to identify any existing problem for you. 

5. Weak Air Flow 

It’s not uncommon for the warm air flow from your furnace to gradually (or suddenly) become weaker than it used to be. 

If it seems that the air flow in your home has declined, it’s worth looking into. Sometimes weakened air flow can be an indicator of a larger pending problem. 

Why does this happen?

The air flow output from your furnace can indicate issues with your fan, belts, or even the motor in your furnace. 

Over time these components can wear, not function as well as they should, and even break down entirely. A good HVAC tech will be able to inspect your unit, give it a proper diagnosis, and offer a solution. 

If you suspect that you have any of the above furnace issues, we would strongly recommend getting your furnace serviced soon to keep your home safe, and to ensure that your system runs smoothly over the cold winter months ahead.

And even if these potential problems don’t apply to you, getting a check up this year will head off any potential problems that may arise over the winter. 

An annual furnace inspection will give you peace of mind and ensure your home stays cozy and warm all winter long.
