Signs Your Furnace Needs Repair

Furnaces usually show warning signs before they stop working completely. Contact us if you notice any of the following:

The furnace won’t turn on or takes multiple attempts to start.
Sulfur, burning or musty smells are coming from the unit.
You hear banging, rattling, grinding or booming sounds during operation.
Some rooms stay warm, while others stay cold.
The system is cycling on and off without reaching the set temperature.
You notice the carbon monoxide detector going off or faint chemical smells near the furnace.

Thorough Diagnostics That Solve the Real Problem

One obvious system malfunction could have different causes. For example, a furnace that keeps shutting off could be due to a bad flame sensor, a failing control board or something as simple as a blocked flue pipe. Our technicians start every repair visit with a full system inspection to get to the root of the issue. Trying to solve problems without understanding the true cause often results in even more damage to the unit, leading to repeat service calls.

We test electrical connections, check ignition components, measure airflow, evaluate heat output, and inspect safety controls like the heat exchanger and flue system. Once we’ve identified the actual problem, we explain what failed, what caused it and the best path forward before we start any work.

Should You Repair or Replace Your Furnace?

If what you’re spending on repair is more than half the cost of installing a new furnace, replacement may be the best option. We also recommend replacing units that are over 15 years old to avoid spending money on repairs for a declining system.

Our technicians will give you an honest assessment so you can decide what fits your budget and needs. We won’t push a replacement if a repair will get you more years of reliable heat.
