What it usually is

• Blower runs, air is cold — ignition or flame sensor. One of the most common calls we get.
• Starts, then shuts off after a minute — short cycling, often a dirty flame sensor or blocked flue.
• Clicks but never lights — igniter, gas valve, or a safety switch doing its job.
• Blows but the house never warms — undersized system, duct leakage, or a failing heat exchanger.
• Bangs on startup — delayed ignition. Worth looking at soon.

One thing we will not skip

If your furnace has a cracked heat exchanger, we tell you and we shut it down. That is a carbon monoxide risk, not an upsell. We carry a CO meter on every heating call.

What you pay

One number for parts and labor, quoted after diagnosis and before any work. No surprises.
