furnace repairDuring the winter months, our furnaces are subjected to heavier use. Although the average lifespan of a furnace is about 20 years, they are often neglected and prematurely stop working. If you think it may be time to call an HVAC service for a furnace repair, here are some things to keep in mind.

If you’ve been noticing a steady increase in heating bills, it may be time for a furnace repair or replacement. Older furnaces often need to work harder to reach the same outcome due to a dirty filter, ductwork issue or general lack of maintenance. If you’ve recently noticed a spike in your heating bills that doesn’t correlate with increased use, it may be time to call for an HVAC home analysis.

Another telltale sign of a furnace in need of repair is water leakage. Water leakage isn’t as dangerous as a gas leakage, but it still needs to be addressed for proper furnace function. Water leakages are generally caused by a clogged condensate line and usually require both plumbing and HVAC expertise to fix.

Hearing strange noises from your furnace is another indication that you may need a furnace repair. There are countless reasons your furnace could be making a weird noise, but one thing is for sure: it won’t just go away on its own. If you hear strange sounds coming from your furnace, call an HVAC repair service.

Finally, a huge red flag when it comes to a furnace repair is a gas or chemical leak. If you smell gas, shut down your furnace immediately, open your furnace, and shut off the gas supply valve. Don’t light any matches or even turn on any lights — this issue definitely requires an HVAC technician to fix, so call your local HVAC service as soon as you possibly can. Alternatively, if you notice that the gas flame on your furnace has changed from blue to yellow, it’s an unmistakable sign of carbon monoxide production and should be addressed immediately. When it comes to dangerous chemicals, leave it for the experts.

Having a well-functioning furnace is especially critical in the winter months. Stay vigilant for signs of malfunction, and don’t hesitate to call an HVAC service for a furnace repair. When it comes to your home appliances, safety always comes first.
