High Desert Winters: Keeping Your Furnace Reliable in Reno’s Cold, Dry Climate

Home | Blog | Published on January 5th, 2026

Winter in Reno is unique. Our high desert climate brings crisp days, frigid nights, and dramatic temperature swings that can put serious strain on your home’s heating system. At DeHart Plumbing, Heating & Air, Inc., we understand exactly what local homeowners face each winter, and we’re here to help you stay warm, safe, and comfortable. When it comes to heating in Reno, reliable performance isn’t just about comfort—it’s about protecting your home and your family through every cold snap.

How Reno’s Climate Impacts Your Furnace

Reno’s winters aren’t just cold; they’re unpredictable. It’s common for temperatures to drop sharply overnight and rebound during the day. These frequent swings force your furnace to cycle on and off more often than in milder climates. Over time, this constant expansion and contraction of metal components increases wear and tear on critical parts like heat exchangers, burners, and ignition systems.

Cold, dry air also affects airflow and efficiency. Furnaces must work harder to heat dense, chilly air, which can reveal existing weaknesses in older or poorly maintained systems. Without proper care, these stresses can lead to breakdowns at the worst possible time—often on the coldest night of the year.

Why Regular Furnace Tune-Ups Matter

Annual furnace tune-ups are one of the most important steps you can take to ensure dependable heat all winter long. During a professional tune-up, our technicians inspect, clean, and adjust key components to keep your system running efficiently. We check for worn parts, tighten electrical connections, and ensure proper airflow, all of which help prevent sudden failures.

Regular maintenance also improves energy efficiency. A well-tuned furnace doesn’t have to work as hard, which means lower utility bills and more consistent indoor temperatures throughout your home.

The Importance of Changing Your Furnace Filter

Your furnace filter plays a bigger role than many homeowners realize. In Reno’s dry climate, dust and debris accumulate quickly. A clogged filter restricts airflow, forcing your furnace to run longer and hotter than necessary. This not only reduces comfort but can also shorten the lifespan of your system.

We recommend checking your filter monthly during heating season and replacing it as needed. Clean filters help maintain even heating, protect internal components, and improve indoor air quality—especially important during winter when homes are sealed tight.

Safety Controls: Protecting Your Home and Family

Furnace safety controls are designed to shut the system down if something goes wrong, such as overheating or improper combustion. In a climate like Reno’s, where furnaces work hard and often, these controls must be inspected regularly. Faulty safety switches or sensors can lead to system shutdowns or worse, unsafe operating conditions.

During routine maintenance, we carefully test these controls to ensure your furnace operates safely and reliably all season long. Proactive maintenance not only prevents inconvenient breakdowns but also gives you peace of mind during Reno’s coldest nights. By addressing small issues early, we help you avoid costly repairs and extend the life of your furnace.

Keeping your furnace dependable through Reno’s cold, dry winters starts with proactive care and trusted local expertise.
