How much does furnace repair cost?
Furnace repair costs can vary depending on the issue, but most repairs fall between $150 and $600. Minor fixes like replacing a thermostat or ignitor may be on the lower end, while more complex repairs—like blower motor or heat exchanger replacements—can cost more. At Northwind Heating & Air, we provide honest diagnostics and upfront pricing, so you’re never caught off guard.
How long does furnace repair take?
Most furnace repairs take 1 to 3 hours, depending on the complexity of the issue and whether replacement parts are readily available. Our technicians at Northwind Heating & Air arrive fully equipped to handle most common repairs on the spot to get your heat back on as quickly as possible.
How often should I service my furnace?
You should service your furnace once per year, ideally before the start of heating season. Regular service keeps your system running efficiently, helps prevent breakdowns, and ensures your home stays warm and safe during Denver’s coldest months.
Can you repair older furnaces that don't meet the new NOx standards?
Absolutely. Colorado's ultra-low NOx law only applies to new furnaces manufactured after December 31, 2025—it doesn't affect existing systems. We repair furnaces of all ages and efficiency levels. Your current furnace can continue operating (and being repaired) as long as it's safe and functional.
The law only matters when you need to replace your entire system. That's why we work hard to keep your current furnace running well—repairs can extend its life and delay the need for a more expensive ultra-low NOx replacement.
