Furnace repair in the Cedar Valley

No heat, cold air, strange noises or a furnace that keeps shutting off. John will find the problem and fix it, usually with parts already on the truck.

Signs your furnace needs repair

  • The house won't reach the temperature on the thermostat
  • The furnace blows cold or lukewarm air
  • It turns on and off every few minutes (short-cycling)
  • Banging, squealing, rattling or humming sounds
  • The igniter clicks but the burners don't light
  • Heating bills jumped without explanation
  • A burning or unusual smell that doesn't go away after the first run of the season
Smell gas? Leave the house right away and call your gas utility's emergency line or 911 from outside. Don't flip switches or use your phone indoors.

How a Greenley furnace repair works

  1. You call and talk to John, not a call center. Describe what's happening and he'll often have an idea before he arrives.
  2. Free diagnosis. John inspects the system and tells you exactly what's wrong.
  3. Clear price before any work. You decide. No pressure, no upselling.
  4. Fixed right. Common parts are carried on the truck, so many repairs are finished the same visit.

All makes and models

Gas furnaces, propane furnaces, older units and high-efficiency models. If it heats a home in the Cedar Valley, we've likely worked on it. Iowa winters are hard on equipment (Waterloo averages around 7,400 heating degree days a year), so a furnace that's struggling in November rarely gets better by January.

Repair or replace?

If your furnace is 15–20+ years old and needs frequent repairs, replacing it may cost less over time. John will give you a straight answer either way. Read our guide: Repair or replace your furnace?

Questions we hear a lot

How fast can you come out?

John responds quickly to service calls, often the same day. Call (319) 404-4031 to check today's availability.

Is the diagnosis really free?

Yes. The initial diagnosis on a service call is free, and you'll know the repair cost before any work begins.

Do you fix furnaces after hours?

After-hours emergency service is available for no-heat situations. Call and John will help you figure out the next step.

Why is my furnace blowing cold air?

Common causes include a dirty filter, a thermostat set to 'fan on', a failed igniter or flame sensor, or a safety switch that has tripped. See our checklist, then call if it's still not heating.
