Winter in Fort Wayne is not gentle. From November through March, our city regularly sees temperatures in the teens and below zero wind chills, extended stretches of freezing temperatures, and heavy snowfall events that test every home system. Your furnace and overall HVAC system need to be ready before the cold arrives — not after the first freeze when every HVAC company in Allen County is suddenly booked for two weeks. Here's how to get your home's heating system properly prepared for a Fort Wayne winter.

Schedule Your Fall Furnace Tune-Up in September or October

The single most important thing you can do to prepare your Fort Wayne HVAC system for winter is schedule a professional furnace inspection and tune-up before the heating season begins. September and October are the right window — after cooling season winds down but before the first cold snap hits and every HVAC company's schedule fills up.

During a fall tune-up, our technicians inspect and clean the burners, test the heat exchanger for cracks, clean the flame sensor, check the ignitor, test safety controls, measure airflow, inspect flue pipes and connections, lubricate moving parts, and test carbon monoxide levels in the flue. This comprehensive check ensures your furnace will perform reliably when Fort Wayne temperatures drop to single digits.

Annual furnace service is also required by most equipment manufacturers to maintain warranty coverage. If your furnace is still under warranty and you haven't been getting annual service, you could be putting that coverage at risk.

Replace Your Air Filter Before Winter

A fresh air filter at the start of heating season is cheap insurance. A clogged filter restricts airflow through the system, causes the furnace to run harder and longer, and can trigger safety shutoffs that leave you without heat on the coldest nights. Change your filter before the first furnace run of the season, and plan to change it monthly throughout the winter — especially if you have pets or a dusty home environment.

The right filter matters too. Very high-MERV filters (MERV 13 and above) improve air filtration but also restrict airflow significantly. Most Fort Wayne residential furnaces operate best with a MERV 8–11 filter. If you're unsure what's right for your system, ask us when we do your tune-up.

Inspect and Protect Your Outdoor Equipment

If you have a central air conditioner or heat pump, the outdoor unit needs attention before winter. For central AC units, install a breathable unit cover to protect the top of the unit from falling debris and ice accumulation — but avoid completely enclosing the unit, which traps moisture and invites rodents. Heat pumps should not be covered at all since they operate year-round in heating mode.

Clear vegetation, leaves, and debris from around your outdoor unit. Fort Wayne falls can deposit significant leaf accumulation around condensers. Ensure the unit is sitting level — frost heave over repeated Fort Wayne winters can shift units out of level, which affects operation and compressor life.

Check Your Vents, Registers, and Ductwork

Walk through your Fort Wayne home and verify that all supply and return air registers are open and unobstructed. Furniture pushed against vents, blocked returns in closets, and closed registers in unused rooms all disrupt the airflow balance your system was designed for. Poor airflow distribution causes comfort problems and puts unnecessary strain on the blower motor.

If you've noticed rooms that are consistently colder than others during previous Fort Wayne winters, fall is the right time to address it — duct sealing, balancing dampers, or supplemental heating solutions are all worth discussing before cold weather makes the problem urgent.

Test Your Carbon Monoxide Detectors

Every Fort Wayne home with a gas furnace should have carbon monoxide detectors on every level, and they should be tested before the heating season. Carbon monoxide detectors have a limited lifespan — typically 5–7 years — and should be replaced when expired. CO detectors are inexpensive insurance against a genuinely life-threatening hazard.
