Boiler Repair, Maintenance & Installation for Des Moines Homes

Hydronic heat is quiet, even and comfortable, and it behaves nothing like a forced-air furnace when it goes wrong. Pressure, circulation and combustion all have to be right together. Obsidian Heating and Cooling covers the full range for Des Moines-area homes heated by radiators, baseboards or in-floor loops: repair, maintenance, and installation and replacement.

We are veteran-owned and a Tempstar Elite Dealer. Boiler work gets a diagnosis of the whole loop, not just the cabinet in the basement.

Complete Care for Hydronic Heating

Boilers are durable when they are looked after and expensive when they are not. These three services cover the whole ownership cycle.

Boiler Repair & Service

No heat, cold radiators, dropping pressure, banging pipes or ignition faults. Our diagnosis works through pressure, temperature and electrical testing plus combustion analysis and gas supply verification before anything gets replaced.

Boiler Repair & Service

Boiler Maintenance & Tune-Up

A fall service visit that protects the investment. We check operating pressure, inspect for corrosion and leaks, confirm safe combustion and venting, and catch the small faults that turn into a no-heat call in the middle of an Iowa cold snap.

Boiler Maintenance & Tune-Up

Boiler Installation & Replacement

A new boiler sized to the home and tied into your existing radiators or in-floor loops, handled from the first assessment through final commissioning so the system is verified before we call it finished.

Where To Start

Which Boiler Service Do You Need?

Start with boiler repair. Ignition faults, a failed circulator and low system pressure all present the same way from inside the house, which is why the diagnosis has to cover the whole loop rather than the cabinet alone. Same-day service is available.

Uneven heat across radiators normally points to trapped air in the loop, a circulation problem or low pressure rather than a failing boiler. It is one of the more common calls we take, and in most cases it is a straightforward repair rather than a reason to replace anything.

Book boiler maintenance in the fall. Corrosion, pressure drift and venting problems are all easier and cheaper to catch before the system is under full winter load, and a maintenance plan keeps the visit on the calendar.

Repeat repairs, visible corrosion or leaks, and heating costs that keep climbing together build the case for replacement. We assess the existing loop first, because a good hydronic distribution system is worth keeping even when the boiler itself is not.

Our boiler versus furnace guide compares the two for Iowa homes, and we also handle furnace services. A boiler only heats, so homes with hydronic heat and no ductwork usually add summer comfort with ductless mini-splits.

Answering Your Questions

Frequently Asked Questions About Boiler Service

Uneven heat across a hydronic system normally points to trapped air in the loop, a circulation problem, or low system pressure rather than a failing boiler. It is one of the more common calls we take, and in most cases the fix is a repair rather than a replacement.

Once a year, ideally in the fall before the system carries full winter load. The visit checks operating pressure, inspects for corrosion and leaks, and confirms that combustion and venting are safe. Skipping it is how a small drift in pressure becomes a no-heat call in January.

Judge the pattern rather than one failure. Repeat repairs, visible corrosion or leaks around the unit, and heating costs that keep climbing together build a stronger case than any single part. We assess the existing distribution loop as part of that, because good radiators and piping are usually worth keeping even when the boiler is not.

No. A boiler only heats. Homes with hydronic heat and no ductwork typically add cooling with ductless mini-splits, which mount room by room and need no ducts at all. We can look at the heating and the cooling side on the same visit.
