Frequently Asked Questions About Furnace Repair

Why does my furnace keep turning on & off?

A short-cycling furnace is often the result of a dirty filter. Your furnace’s filter needs to be changed every few months to avoid becoming clogged. Short-cycling can also be caused by thermostat issues or a poorly sized furnace.

How expensive are furnace repairs?

Wondering what furnace repair costs? The answer depends on the scope of the repairs, the parts required, and how long the job takes to complete, as well as the specific make and model of your furnace. According to Home Advisor, the national average furnace repair cost is $287, with a typical range of $131 to $453. On the low end, replacing a thermostat may cost a few hundred dollars or less, while replacing a blower motor can be several hundred dollars or more. Installing a new heat exchanger could be well over a thousand if one is still available for your system.

Our experts at National Heating & Air Conditioning can inspect your furnace and help you choose the best course of action for your needs and budget. We will explain all your repair options, as well as alternatives, like system replacements, and give you honest advice that will help you make the best decision possible.

Why isn’t my furnace working?

The most common reason that a furnace isn’t working (or isn’t running effectively) is due to lack of maintenance. Routine preventative maintenance is the single most important investment in the overall efficiency and service life of your furnace.

How can I properly maintain my furnace?

While DIY maintenance shouldn’t replace your annual tune-up, there are some things you can do to keep your furnace in top shape. Dusting and cleaning your burners will allow your furnace to operate more efficiently, as well as keeping the areas around your furnace clean and clear.

Why does my ductwork make popping sounds?

When forced air begins blowing through your furnace’s ductwork, it’s normal to hear the sound of your ducts filling up. However, if you hear strange noises like whistling or loud popping, it could indicate insufficiency in your ducts. Your local HVAC professional will be able to determine the exact cause and provide quick solutions.
