5 Warning Signs You Need Professional HVAC Service This Winter


Keep Your Home Comfortable and Safe This Season

As temperatures continue to drop across Derry, Londonderry, Nashua, and Hudson, NH, homeowners need to stay vigilant about their heating systems. At Paul The Plumber, we regularly encounter situations where earlier intervention could have prevented major heating system failures during the coldest months of the year.

Here are five critical warning signs that indicate you need professional HVAC service:

1. Unusual Noises

If your furnace is making banging, whistling, or scraping sounds, it’s trying to tell you something’s wrong. These noises often indicate loose components, failing motors, or other mechanical issues that require immediate attention.

2. Rising Energy Bills

When your heating costs suddenly spike without a corresponding increase in usage, your system is likely working harder than it should. This inefficiency often stems from worn components or maintenance issues that professional technicians can readily address.

3. Uneven Heating

Cold spots throughout your home aren’t just uncomfortable; they’re signs that your heating system isn’t distributing warmth effectively. This could indicate ductwork problems, failing components, or an aging system that’s struggling to keep up with demand.

4. Frequent Cycling

If your furnace constantly turns on and off, it’s short cycling. This not only wastes energy but can also indicate serious problems with your thermostat, flame sensor, or other crucial components.

5. Yellow Pilot Light

A healthy furnace flame should be blue. If you notice a yellow flame, this could indicate dangerous carbon monoxide production, requiring immediate professional attention.
