If you aren’t really using your furnace more, but your home heating bills are increasing more than they should, it could be that your furnace is losing efficiency and is due for repair.

All HVAC systems make some noise, but if your furnace is making odd noises—especially clanging—it’s a sign you should have it examined by an expert.

Known as short cycling, a furnace that keeps starting and stopping instead of turning on and running steadily through its cycle most likely demands repair from an experienced HVAC technician like the team members at Pratt Brothers.

Furnaces shouldn’t stink. If there’s a persistent nasty smell coming from your furnace, it’s a sign you should seek repair.

Furnace Repair: Frequently Asked Questions

You may notice uneven heating, new or loud sounds coming from the unit, short cycling, burning or musty odors that don’t go away, or a sudden rise in energy bills. If your system isn’t keeping up, it’s smart to schedule a diagnostic.

If you smell gas or a carbon monoxide alarm goes off, turn the furnace off, get to fresh air, and contact emergency services and your HVAC company. For non-emergency issues, it’s often okay to run it briefly, but continued operation can worsen the damage.
This can happen due to thermostat settings, a dirty air filter, ignition issues, a flame sensor issue, or overheating that triggers a safety limit. A technician can test the system safely and recommend the right fix.
Many repairs can be completed in a single appointment, but the timeline depends on the issue, system accessibility, and parts availability. After diagnosing the problem, your technician can give you a realistic timeframe.
A furnace may be a better candidate for replacement if it needs frequent repairs, is older and inefficient, or has major component issues. If the problem is isolated and the system has been well maintained, repair is often the most practical route. A pro can help you weigh efficiency, reliability, and long-term costs.
