Let’s Work Together to Avoid a Holiday Breakdown

Home | Blog | Published on November 24th, 2025

As the holiday season approaches, the last thing any homeowner wants is a heating system that quits just as guests arrive or temperatures plunge. Aging furnaces, boilers, and heat pumps are especially vulnerable during the coldest months of the year, when they’re pushed to work harder and longer than usual. Fortunately, a few smart steps can significantly reduce the risk of an inconvenient—or expensive—holiday breakdown.

Keep Filters and Vents Clean

One of the simplest, most effective ways to help an older heating system run reliably is to ensure proper airflow. Dirty or clogged filters force the system to work harder, which not only reduces efficiency but also increases the risk of overheating and shutdowns. Make it a habit to check filters monthly and replace them every one to three months, depending on usage and household factors such as pets or allergies.

Blocked vents or registers can also strain an aging system. Make sure furniture, curtains, or decorations aren’t obstructing airflow. If you have a boiler system with radiators, check that the surrounding areas are clear and that radiators are heating evenly.

Don’t Ignore Strange Noises or Odors

Older heating systems often give warning signs before breaking down—if you know what to listen for. Banging, rattling, grinding, or squealing noises can indicate worn bearings, loose components, or motor problems. Unusual odors, such as burning smells or a sour scent, may point to electrical issues or poor combustion. These symptoms rarely resolve on their own and can quickly escalate during heavy holiday usage. Scheduling service at the first sign of trouble can prevent a major failure later.

Give Your Thermostat a Checkup

A surprising number of “heating failures” turn out to be thermostat issues. Aging systems rely heavily on accurate thermostat readings to cycle properly. If your home feels chilly even though the thermostat is set correctly, start by checking the batteries, cleaning dust from the sensor area, and ensuring the thermostat is away from heat sources or drafts. If the system still struggles to maintain temperature, it may be time for a professional to evaluate whether the thermostat or the equipment needs attention.

Avoid Overworking the System

During the holidays, guests, cooking, and festive activities can increase indoor heat. Instead of cranking the thermostat higher when it gets cold outside, try maintaining a steady temperature. Large temperature swings—turning the heat way down during the day and far up at night—force an aging system to work overtime, increasing wear and tear. Keeping the home at a consistent, comfortable setting helps reduce strain and lowers the risk of a breakdown.

Schedule Professional Maintenance or Repairs

For aging heating systems, professional maintenance is one of the best preventive steps you can take. A trained technician can identify worn components, clean internal parts, check safety controls, test the ignition system, and verify that the equipment is operating safely and efficiently. This is especially important for furnaces and boilers, where undetected issues can lead to carbon monoxide risks or complete system failure.

If your system is more than a few years old, annual maintenance isn’t just recommended: it’s essential. Proactively repairing or replacing failing components before the holiday season can save you from a cold home, emergency repair costs, and stress during an otherwise joyful time of year.
