From creaking noises to musty odors, HVAC systems at risk of failure will cry out for help in a variety of ways. The key is knowing how to look and listen for these common signs of ill health. To avoid waking up shivering this winter, look for the following indications that you need furnace repair in your Baltimore home.

Your Furnace Runs Non-Stop

A typical furnace will kick on at varying points throughout the day, depending on your heating needs. If your furnace seems to be running constantly, it could be a sign of a faulty thermostat or more serious internal problems. In poorly insulated homes, furnaces need to work overtime to maintain the desired temperature. A furnace also may need to put in extra effort to pump air through dirty air filters and ducts. If you’re unable to pinpoint the problem, it’s best to call a licensed technician for a professional inspection.

You Hear Loud Noises as Your Furnaces Kicks On

Furnaces are well known for the low, rumbling noise they give off when running. If you hear noises from your furnace that stand out—such as screeching, loud bangs, and grinding—it’s likely a sign that your unit needs immediate furnace repairs. Screeching noises are typically a sign of blower motors in need of repair, while other sounds can point to a range of other problems. Generally, if you hear noises beyond your blower turning on and off, call a technician for help.

Your Heating Bills Suddenly Go Up

Every Baltimore homeowner expects heating bills to go up in the depths of winter, but bills that shoot up rapidly—and unexpectedly—could point to problems in your furnace. Heating units that have lost efficiency need to work harder to produce the same amount of heat, sending your energy costs sky high. If your furnace turns on and off constantly, it’s a good indicator that you may need furnace repair or replacement in your Baltimore home.

Your Furnace Produces No Heat

It stands to reason that a furnace that produces no heat isn’t working properly, yet many homeowners only learn of a broken furnace when they need it for the first time in the winter. Don’t let this be you. Instead, be sure to test out your HVAC system before the heating season begins to ensure that it is working properly when you really want it to.
