Fast, Reliable Furnace Repair Across Des Moines
Most furnace repairs in Des Moines run $150-$700 and our technicians can usually diagnose the problem on the first visit. We dispatch from our Seattle office and carry the parts to fix Goodman, Rheem, York, and other major brands without ordering and waiting.
We’re familiar with the homes here. The ranch-style and split-level houses built during the 1950s-70s suburban buildout on the marine terrace, the properties tucked back from Pacific Highway South, the western neighborhoods catching salt spray off Puget Sound near the Marina. Many were originally heated by electric baseboard or oil furnaces with no duct systems at all. When your furnace quits on a January morning and the house drops fast, you need someone who knows what they’re walking into. Call (817) 402-2972. A live person answers, 24 hours a day, and we’ll give you a firm arrival window.
Why Coldharbour Heating & Air Is Des Moines’s Preferred Furnace Repair Company
Des Moines homeowners have been let down before. A no-show. A price that jumped once the truck was in the driveway. A repair that failed before the invoice was paid. We started Coldharbour Heating & Air in 2003, and we operate as an independently owned member of the Kingswell network. That means we follow The Kingswell Way: say the price before the work starts, show up in the window promised, leave the place cleaner than we found it, put every guarantee in writing, and come back if it fails.
Our 365-Day Done Right Promise is not conditional and not verbal. The technician hands you a written guarantee before leaving. If that same repair fails within 365 days, we return and correct it at no charge. No argument, no additional diagnostic fee.
Phones are answered by a live person around the clock, every day of the year. No voicemail trees. No “call back in the morning” when your furnace quits at midnight and the temperature’s dropping toward freezing.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The technician who shows up can work on whatever system is already in your home.
Furnace Tune Up in Des Moines
A Furnace Tune Up in Des Moines typically costs $80-$200 and should happen every fall before the heating season starts. Given the damp marine climate here and the age of much of the housing stock, deferred maintenance shows up as blower motor strain, corroded flame sensors, and heat exchanger stress that a annual visit catches early.
What the Visit Covers
We pull and clean the burner assembly, check gas pressure or propane regulator settings, test the heat exchanger for cracks, measure temperature rise across the furnace, and inspect the blower motor and capacitor. For homes that went through the Port of Seattle’s Residential Sound Insulation Program, we also verify that the furnace isn’t short-cycling against a tightened envelope it was never sized for.
Why Tune-Ups Matter on Older Systems
Many Des Moines furnaces are 15-25 years old, serving homes that have been re-enveloped with upgraded windows and added insulation. The original load calculation is now wrong. A tune-up lets us spot the mismatch before it becomes an emergency call at 2 a.m. in February.
Emergency Furnace Repair in Des Moines
Emergency Furnace Repair in Des Moines covers after-hours diagnosis and repair when your system fails during cold weather, and it runs the same $150-$700 range as standard repairs. We do not charge overtime premiums. The price is written before any work begins, even at midnight on a Saturday.
When to Call Immediately
Call if you smell gas, hear a loud bang at startup, see the burner flame rolling out of the cabinet, or if the carbon monoxide detector alarms. These are not wait-until-morning situations. For suspected gas leaks, evacuate and call your utility first, then call us. For other failures, a live person will answer and dispatch a technician with a firm arrival window.
What We Carry on Emergency Calls
Our trucks stock ignitors, gas valves, blower motors, capacitors, control boards, and flame sensors for Goodman, Rheem, York, and other common brands. We also carry propane-rated parts for rural Des Moines properties where natural gas never reached the lot. Most emergency repairs are completed in a single visit.
Trusted Brands We Service in Des Moines
Our technicians are trained to service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock local parts for Goodman, Rheem, and York systems, which means faster turnaround for Des Moines homeowners and fewer return trips. Whether you have a 30-year-old propane furnace on a rural lot east of Pacific Highway or a newer gas system in a soundproofed home near the Marina, the technician who arrives can diagnose it, source the part, and fix it.
Common Furnace Repair Problems We See in Des Moines Homes
- Oversized furnaces short-cycling in soundproofed homes. Thousands of Des Moines properties were re-enveloped through the Port of Seattle’s Residential Sound Insulation Program. The tightened building envelope means the original furnace, sized for leaky 1950s-70s construction, now heats the space too quickly and shuts off before completing a full cycle. This wears out components prematurely and wastes fuel.
- Ignition and control-board failures on aging propane and oil furnaces. Rural Des Moines properties beyond the natural gas mains often run propane or older oil systems. These see hard starts after summer dormancy, corroded spark ignitors from the damp marine air, and control boards stressed by voltage fluctuation on longer supply lines.
- Blower motor and capacitor failures on outbuilding and workshop systems. Properties with detached shops or barns often have second heating systems that sit idle for months. Deferred tune-ups mean seized bearings, cracked blower belts, and failed capacitors that only surface when the owner fires the unit up for a winter project.
- Accelerated corrosion on outdoor equipment near the Marina. Salt-laden marine air off Puget Sound pits condenser coils and copper refrigerant fittings within a half-mile of the Des Moines Marina and waterfront bluff. This is a routine service pattern for our western neighborhoods, largely absent in inland Renton or Kent.

FAQs About Furnace Repair in Des Moines
Yes. The added insulation and upgraded windows tighten your home’s envelope significantly, which often means your original furnace is now oversized. We run a proper load calculation to confirm, and if the unit is short-cycling, we may recommend repair strategies that address the mismatch or discuss right-sizing if replacement is near. Call (817) 402-2972 for a free estimate.
Yes. We service propane furnaces on properties where natural gas never reached the lot. Our trucks carry propane-rated regulators, orifices, and control parts, and our technicians are trained on the pressure settings and venting requirements that differ from natural gas systems.
Salt-laden marine air off Puget Sound accelerates pitting on aluminum condenser fins and copper refrigerant fittings. Equipment within a half-mile of the Marina sees this routinely. We clean and treat coils during service calls and can recommend protective coatings or more corrosion-resistant replacement equipment when the time comes.
We typically arrive within a few hours for emergency calls in Des Moines, with a firm arrival window given when you call. Our Seattle-based dispatch coordinates local crews, and a live person answers the phone 24 hours a day. Call (817) 402-2972 anytime.
Yes. We size and install heating systems for detached shops, barns, and outbuildings, accounting for exposed locations with no wind shelter and intermittent use patterns. These systems often benefit from ductless mini-split solutions, which are an outsized part of our Des Moines market given the number of homes here that originally lacked duct systems entirely.
