Preparing Your HVAC System for Winter: Essential Maintenance Tips

As the first chilly gusts rattle the windows, many homeowners and small business owners feel a familiar worry: Will the heat hold up all winter? When your comfort—and safety—are on the line, a reliable HVAC system isn’t just a luxury. It’s a necessity.

At Briggs Heating, we know a well-tuned system is the difference between a cozy winter and an emergency hvac call at 2 a.m. Our certified professionals have seen it all, from worn-out filters to furnaces that wheeze instead of roar. Let’s walk through essential steps to keep your system humming all season.

Why Winter HVAC Maintenance Matters ❄️

Think of your HVAC system as the heart of your home or business. When it works smoothly, everyone stays warm, energy bills stay manageable, and dangerous breakdowns are kept at bay.

• Energy Savings: According to the U.S. Department of Energy, regular maintenance can reduce energy use by up to 15%. That’s real money back in your pocket.
• Safety First: Gas leaks, carbon monoxide, and electrical shorts are silent threats. Routine checks catch these hazards before they become emergencies.
• Avoiding Emergencies: A minor issue today can snowball into a major repair tomorrow—often at the worst possible time.

Skipping winter prep is like driving on bald tires in a snowstorm: risky, stressful, and ultimately more expensive.

Pre-Winter HVAC Checklist

Before the frost sets in, grab this checklist and give your system a fighting chance:

• Furnace Inspection: Check for unusual noises, rust, or water leaks. If something feels off, don’t wait.
• Filter Replacement: Dirty filters choke airflow and strain your system. Swap them out every 1–3 months.
• Thermostat Calibration: Make sure your thermostat reads accurately. A few degrees can mean a world of difference.
• Duct Sealing: Leaky ducts waste heat and money. Inspect for visible gaps or loose connections.
• Ventilation Checks: Clear vents and exhausts of dust, debris, and blockages. Good air flow equals better comfort.

These steps aren’t just for show. They’re the foundation for a safe, efficient winter.

Furnace and Heating System Care

Your furnace is the workhorse of winter. Show it some love:

• Listen for Trouble: Banging, rattling, or whistling usually means something’s wrong.
• Smell for Danger: A musty or burning odor can signal mold or electrical issues.
• Check the Flame: A healthy gas flame burns blue. Yellow or orange? Time for a professional look.

Repair vs. Replace:
If your furnace is over 15 years old, or needs frequent repairs, replacement might be the wiser investment. Newer models offer better efficiency and safety features.

Professional Tune-Ups:
Certified HVAC technicians (like those at Briggs Heating) follow industry best practices, including those from ASHRAE and the EPA. A tune-up covers:

• Inspecting heat exchangers for cracks
• Testing safety controls
• Cleaning burners and ignition systems
• Checking for carbon monoxide leaks

A pro’s trained eye can spot what DIY checklists miss.

Emergency Preparedness Tips

Winter storms and power outages don’t wait for business hours. Here’s how to stay ready:

• Generator Maintenance: Test your backup generator monthly. Check oil levels, battery charge, and fuel supply.
• Know Your Emergency HVAC Contact: Save Briggs Heating’s number in your phone—you’ll thank yourself if the heat goes out at midnight.
• 24/7 Emergency Service: Our team is always on call, ready to respond when you need us most.

When the unexpected hits, a little planning goes a long way.

Extend Your System’s Life: Pro Tips

Want to squeeze every year out of your HVAC investment? Try these:

• Schedule Annual Maintenance: Once a year, have a certified professional inspect and tune your system.
• Keep Vents Clear: Don’t block supply or return vents with furniture, rugs, or boxes.
• Upgrade Your Thermostat: Programmable or smart thermostats help manage energy use and comfort.
• Monitor Indoor Air Quality: Consider air scrubbers, humidifiers, or dehumidifiers to keep air fresh and healthy.
• Clean Ducts as Needed: Dust, dander, and debris can build up over time, especially if you have pets or recent renovations.

These habits help keep your system running like a well-oiled machine.

The Cost and Time Factor

Worried about maintenance eating up your weekend or wallet? Here’s what to expect:

• Time: Most professional tune-ups take 1–2 hours. Filter changes and thermostat checks can be done in minutes.
• Cost: Routine maintenance is far less expensive than emergency hvac repairs or a full system replacement. Think of it like changing your car’s oil—small investment, big payoff.

Neglect, on the other hand, can lead to frozen pipes, costly repairs, or even total system failure.

When It’s an Emergency

Sometimes, no matter how well you prepare, things go sideways. Call for emergency hvac help if you notice:

• No heat or airflow from vents
• Unusual smells—especially gas or burning
• Loud, persistent noises
• Water pooling near your furnace or air handler
• Carbon monoxide alarms sounding

Don’t wait. Safety comes first.

Winter HVAC FAQ

How often should I replace my filter in winter?
Check monthly and replace at least every 1–3 months. More often with pets or allergies.

Is it okay to close vents in unused rooms?
No. Closing vents can unbalance your system, leading to pressure problems and reduced efficiency.

What’s the safest thermostat setting for winter?
Most sources, including ENERGY STAR, recommend 68°F when you’re home, and lower when you’re away.

Can I do my own furnace maintenance?
You can handle basic tasks like filter changes, but deeper inspections should be left to certified professionals.

Special Considerations for Winter HVAC Service

• Older Homes and Buildings: May have outdated wiring, insulation, or ductwork. Extra care is needed.
• Businesses with Sensitive Equipment: Ensure proper air balancing and humidity control to protect electronics and inventory.
• Health Concerns: If anyone in your home or business is sensitive to dust or allergens, prioritize indoor air quality solutions like HEPA filters or air scrubbers.

Refer to guidelines from the U.S. Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) for additional safety and maintenance standards.
