AC & Furnace Repair in Gladstone, MO

Duct Daddy handles heating & cooling for Gladstone homeowners the honest way: one price up front, our own licensed crew, and no upsell games at the door. We cover Gladstone and the rest of Clay County, and we treat your house like it is on our own street.

Because we also run jobs in neighboring Liberty, Parkville and Kansas City, we know Clay County homes and how they are built, so nothing about your heating job catches us off guard.

Repairs, Tune-Ups, and Installs

We publish our flat-rate repair menu instead of hiding it, the price includes the part and the labor to install it, and the $100 diagnostic comes off your bill if we do the repair the same day. Need a whole new system? We install Trane's Oxbox line, same factory and same parts network as the systems that cost two thousand more, sized for your home by our own crew and never subbed out. See the full repair menu and equipment we install.

No Heat? Here Is What It Usually Is

Most no-heat calls in Gladstone come down to one of five things, and four of them are cheap. We publish what they cost so you know before we pull in the driveway.

• Dirty flame sensor. Furnace lights, runs a few seconds, shuts back down, tries again. This is the single most common no-heat call there is. Cleaning it is $125. If it needs replacing, $175.
• Failed hot surface igniter. Blower runs but it never lights. $250.
• Tripped limit or rollout switch. Usually a symptom of something else, so we find the cause instead of just resetting it. $300.
• Pressure switch. Often a blocked flue or condensate line rather than the switch itself. $350.
• Draft inducer motor. The expensive one, and it genuinely varies by unit. From $600, and you get the exact number in writing before we touch anything.

The diagnostic is $100 and it drops to $0 if we fix it the same day. You approve the price before any work starts. No overtime rates, no trip fee stacked on top.

If you smell gas, do not wait on us. Get everyone outside, do not flip any switches, and call 911 and your gas company. Spire is 800-582-1234 on the Missouri side, Kansas Gas Service is 888-482-4950 on the Kansas side.

What a Tune-Up Covers

• Heat exchanger, burners, ignitor, and gas pressure on the furnace
• Coil, refrigerant charge, capacitor, contactor, and drain on the AC
• Electrical and safety controls checked
• Photo report of what we found
