Don't Ignore the Signs

Common Symptoms of a Failing Furnace

Your furnace will often show signs of trouble before it fails completely. Knowing these warning signs can help you avoid a mid-winter breakdown. If you notice any unusual noises like banging, popping, or squealing, it’s a clear indication that a component may be failing. A yellow or flickering pilot light, instead of a steady blue one, can signal a ventilation or gas supply problem that requires immediate attention.

Other common symptoms include a sudden increase in your energy bills, cool air coming from the vents, or the system cycling on and off more frequently than usual. If you experience any of these issues, don’t wait for the problem to get worse. Contact the professionals at John Nugent & Sons for a thorough inspection and expert repair to keep your system running safely and efficiently.

Protect Your Investment

Proactive Furnace Maintenance & Tune-Ups

Annual maintenance is the best way to keep your furnace running safely, efficiently, and reliably throughout the heating season. A professional tune-up from John Nugent & Sons helps prevent unexpected breakdowns, extend your equipment’s lifespan, and keep your energy bills in check. During a maintenance visit, our technicians thoroughly inspect your system.

We inspect critical components like the burner, heat exchanger, and blower motor. We also check electrical connections, test safety controls, and lubricate moving parts to reduce wear. This proactive service not only improves your system’s performance but also helps us catch small issues before they become major, costly repairs. Scheduling regular maintenance is a simple way to protect your investment and ensure peace of mind.

The Benefits of Annual Service

Why Furnace Tune-Ups Are Essential

A well-maintained furnace does more than heat your home; it also improves safety and efficiency. During a tune-up, our technicians inspect the heat exchanger for cracks that could cause carbon monoxide leaks, helping keep your family safe. We also replace your air filter, which improves airflow and indoor air quality while reducing strain on the system.

A calibrated furnace operates more efficiently, consuming less energy to produce the same amount of heat. This translates directly into lower monthly utility bills. Regular maintenance also helps meet your manufacturer’s warranty requirements, keeping it valid if a major component fails. Don’t skip this crucial service—schedule your furnace tune-up with us today.
