Ductless Mini-Split Services: Comfort Where Your Ductwork Never Reached

Additions, converted attics, finished basements and sunrooms all share one problem: the original ductwork does not go there. A ductless mini-split conditions those spaces on their own zone without opening up the house. Obsidian Heating and Cooling covers all three services across Des Moines and the metro: repair, maintenance, and installation.

We are a veteran-owned team and a Tempstar Elite Dealer, and we install LG ductless systems. Each zone gets its own temperature control, which is why mini-splits solve the one room that never matches the rest of the house.

Our Mini-Split Services

Zoned Comfort, Start to Finish

Mini-splits run quietly enough that homeowners forget they need service. They still do. Here is how we cover them.

Mini-Split Repair & Service

A head unit that blows weakly, a zone that stopped keeping up, unusual noises, or a system that will not respond at all. We diagnose the indoor head, the line set and the outdoor unit together rather than treating them as separate problems.

Mini-Split Repair & Service

Mini-Split Maintenance

Annual service on every head: filters and coils cleaned, refrigerant and airflow verified, condensate drainage checked. Zone systems still accumulate the same dust and wear as ducted equipment, they just do it silently.

Mini-Split Maintenance

Mini-Split Installation

Design through finish, with head placement and zone count planned around how you actually use the rooms. Our Iowa ductless guide is a good place to start if you are still deciding.

Where To Start

Which Mini-Split Service Do You Need?

Weak or uneven airflow is the most common ductless fault we see, and it usually traces to a dirty filter or coil, a refrigerant problem, or a frozen coil. All three are repairable, and none of them improve on their own. Book mini-split repair.

This is the usual story with ductless. The system is quiet, so it gets forgotten until something fails. Annual maintenance on each head keeps the filters and coils clean and catches refrigerant issues while they are still small.

A bonus room over the garage, a finished attic, a three-season porch. If the ducts never reached it, no amount of central system tuning will fix it. That is a mini-split installation, and it is the single most common reason homeowners call us about ductless.

Houses heated by a boiler and radiators have no ducts to add cooling to. Ductless is the standard answer, because it delivers both heating and cooling room by room without any duct run at all.

If the goal is the entire home and your ducts are sound, a ducted heat pump is usually the better fit. Mini-splits are strongest where ducts are absent, awkward or not worth extending.

Answering Your Questions

Frequently Asked Questions About Ductless Mini-Splits

Anywhere the ductwork never reached. Additions, converted attics, finished basements, sunrooms and bonus rooms over garages are the classic cases. It is also the standard way to add cooling to a home heated by a boiler and radiators, since there are no ducts to work with at all.

Yes. A ductless system is a heat pump, so the same equipment cools in summer and heats in winter. Each zone is controlled separately, which is why homeowners use them to fix one persistently uncomfortable room without changing anything about the rest of the house.

Once a year, on every head. The visit covers filter and coil cleaning, refrigerant and airflow checks, and condensate drainage. Because ductless systems run so quietly, they tend to get overlooked, and the annual service is what catches airflow and refrigerant problems while they are still small.

Weak or uneven airflow is the most common ductless complaint. It usually traces back to a dirty filter or coil, a refrigerant problem, or a frozen coil. All three are repairable, and none of them get better on their own, so it is worth a service call rather than a wait.
