It’s common for homeowners to neglect their furnace until a significant problem arises. If you want to avoid major breakdowns and costly repair bills, it is essential to pay attention to some warning signs. Here, the HVAC experts at Donovan & Jorgensen in New Berlin, WI, share a few indicators your furnace needs repairs.

How to Tell Your Furnace Needs Repair

1. Weak Airflow

Does it feel like you can only barely feel warm air coming from your vents? There could be many reasons for this problem, such as worn belts or malfunctions in the fan. The problem may be the fan motor itself, which requires professional repairs.

2. Your Thermostat Can’t Keep Up

Your thermostat tells your furnace which temperature to maintain. If you are continually cranking up the thermostat with little change in temperature, the problem could be a blown fuse. It could also be a symptom of loose wiring or a blown circuit breaker.

3. Cycling

Cycling is when your furnace turns itself on and off repeatedly, which means the appliance is running more often than it should to reach the desired temperature. It may be caused by improper airflow as the result of a leak in the ductwork. More commonly, it is the result of a clogged air filter.

4. Sudden Spike in Utility Bills

When your utility bills increase sharply without any apparent cause, there’s an underlying problem. However, it can be tricky to diagnose. The issue could be a leak in the ductwork, clogged air vents that force the unit to work overtime to compensate, or electrical problems. 

Your furnace will likely give you some warning signs that a potential problem is on the horizon. Paying attention to these signs can help you avoid costly repair bills.
