10 Signs That Your Furnace Is Working Too Hard

When winter strikes, the last thing any homeowner needs is a malfunctioning furnace. Most modern homes use gas furnaces as their primary heating sources, because they provide an efficient, cost-effective distribution of heat. In cold weather climates, an optimally running furnace is a must-have, so it definitely pays to know what to look for as far as problems are concerned.

What to know about furnace faults

These devices are not without their issues, but failure to address minor damage early on can lead to some major, costly repairs. An essential part of preventative maintenance is understanding the common, telltale symptoms that furnaces experience when problems arise.

If yours is or has been demonstrating one or more of these symptoms, do not fret. So long as you get in touch with a licensed HVAC contractor as soon as possible, the repair bill is not likely to be too high. Without further ado, here are the troubling signs of a furnace that is simply not working well!

Gas leaks – You know there is a problem when you smell gas coming from your furnace, and it is at this point that you should take immediate action. The safety risks of a gas leak cannot be overemphasized, so pick up the phone, and call an emergency HVAC contractor.

Cracked heat exchanger – the heat exchanger is responsible for a furnace’s combustion phase. Air passes over the device on its way through the ductwork. When damaged (on account of normal wear and tear or other, unintended causes), the exchanger may leak carbon monoxide gas into your home. Need we say more?

Dust blowing out of your vents – maintaining healthy air quality in your home is very important, and this is where your furnace filter and duct lines come into play. Dirty and/or clogged filters force the heating system to work harder, since they hinder normal airflow. Not only can this cause dirt and other airborne contaminants to find their way into your house, it can also significantly reduce a furnace’s lifespan!

Higher than normal energy bills – do not mistake a marked rise in your home heating bill to be due only to the weather. Despite the age or brand, every overworked furnace naturally leads to an increase in gas usage. The harder the system has to work to heat the house, the more fuel it must consume. Keep a watchful eye on your utility bills, and compare them to latter years to be on the safe side.

Pilot light not staying lit – the pilot light has is a simple part with a simple purpose. However, when it does not work, you can expect big problems. A standard replacement may be necessary to keep the system running, as it should!

Other common problems that may indicate your furnace is being overworked include broken parts, the continual need to reset the thermostat, loud groaning or whining noises coming from the furnace when it is running, a pilot light flame that is yellow instead of blue, and the presence of cold spots in your house. Whatever the case may be, you would be wise to call a local HVAC company for help!
