Furnace Services in Des Moines, IA: Repair, Maintenance & Installation

A gas furnace is the system an Iowa winter tests hardest, and the one you notice only when it stops. Obsidian Heating and Cooling covers all three sides of furnace ownership for homeowners across Des Moines and the metro: repair when the heat quits, maintenance that keeps it from quitting, and installation when a system has run out of road.

We are a veteran-owned team and a Tempstar Elite Dealer. Every visit starts with a real diagnosis rather than a guess, and you get the cost before we start the work.

Three Ways We Keep Your Heat On

Most furnace calls land in one of three places. Pick the one that matches your situation, or call and describe what the system is doing and we will point you to the right service.

Furnace Repair & Service

No heat at all, short cycling, loud banging or squealing, weak heat output, ignition problems, or heating bills that climbed without an explanation. We test components rather than guessing, then explain what is wrong in plain language.

Furnace Repair & Service

Furnace Maintenance & Tune-Up

The fall visit that prevents the winter emergency. We clean the burners and flame sensor, check the heat exchanger, verify gas pressure and airflow, and catch the wear that turns into a no-heat call in January.

Furnace Installation & Replacement

When repair stops making financial sense, we size the replacement to your home rather than to the unit that came out. As a Tempstar Elite Dealer we have direct manufacturer support behind the install.

Where To Start

Which Furnace Service Do You Need?

Check your thermostat setting, your filter and your breaker first, then call us. Most no-heat calls come down to a dead ignitor, a dirty flame sensor, a tripped limit switch or a thermostat fault, and all four are repairable. Start with furnace repair.

Furnaces should run quietly. Banging can point to a cracked heat exchanger, squealing to a failing blower bearing, grinding to a blower wheel striking its housing. Our guide to what furnace noises mean breaks the sounds down, and any of them is worth a repair visit.

A clogged filter, leaking ductwork or general component wear costs you money all winter without ever tripping an alarm. A tune-up with a combustion analysis usually finds it, and a maintenance plan keeps it from coming back.

Age and repair scope decide it. A minor repair on a newer furnace is worth doing; a major repair on an aging one usually is not. We will do the math with you on your specific system before you spend anything, and if replacement wins we handle the installation.

A furnace heats air and moves it through ducts. If your home has radiators instead, that is a boiler. Our boiler versus furnace guide compares them, and a heat pump can cover heating and cooling from one system.

Answering Your Questions

Frequently Asked Questions About Furnace Service

Once a year, in the fall before you start relying on it. An annual tune-up cleans the burners and flame sensor, verifies gas pressure and airflow, and inspects the heat exchanger. It is the cheapest furnace work you will pay for, because it is the visit that prevents the emergency one.

A dead ignitor is the most common, especially on older furnaces. After that comes a dirty flame sensor that shuts the system down seconds after ignition, a tripped limit switch, a failed blower motor, a thermostat fault, or a gas supply problem. Every one of those is a repair rather than a replacement.

It depends on the age of the system and the scope of the repair. A minor repair on a relatively new furnace is worth doing. A major repair such as a heat exchanger on an aging system usually is not, because you are spending significant money on equipment that is near the end of its life anyway. We will walk through the numbers on your specific furnace before you commit to either path.

We are a Tempstar Elite Dealer, which gives us direct access to manufacturer technical bulletins, diagnostic flowcharts and parts. We repair and maintain furnaces of every make and model regardless of who installed the original system.
