Ductless Mini-Split Installation in Washington County, PA

Residential ductless mini-split repair, replacement and installation for homes across Washington County and the South Hills. The owner does the work himself.

Not every room is reachable by ductwork, and not every home has ducts at all. A ductless mini-split heats and cools a space without any ducts — an outdoor unit connects to one or more indoor wall units, each with its own control. It's a clean fit for older homes with radiators, homes with no ductwork, additions, finished attics and basements, garages, and that one room that never gets comfortable. We handle residential mini-split repair, replacement and installation for homes in Houston, Canonsburg, Washington, McMurray, Cecil Township, McDonald, Bethel Park, Upper St. Clair, Bridgeville, South Fayette and the towns in between. You get a clear answer and a price before any work starts.

Where a mini-split earns its keep

A mini-split makes the most sense in the spots your main system can't reach.

  • A room over a garage

    Always too hot in summer and too cold in winter.

  • A finished basement or attic

    Converted to living space with no ducts run to it.

  • A sunroom

    Lots of glass, hard to keep comfortable from the main system.

  • A home addition

    You don't want to overload your current system or run new ducts.

  • An older home with radiators

    No ductwork at all, but you want cooling somewhere.

  • The room that's never right

    One room that's always hotter or colder than the rest.

Zoning room by room

The thing that sets a mini-split apart is zoning. Each indoor unit has its own control, so you can set the bedroom cooler for sleeping, leave the guest room off until someone visits, and keep the sunroom comfortable only when you're using it. You're heating or cooling the space you're actually in, not the whole house.

One outdoor unit can run several indoor units, so a whole home without ductwork can be done room by room. The right layout depends on the space and how you use it. We come out, look at what you have, and give you an honest read instead of a sales pitch.

We install Goodman, Comfortmaker, Rheem and Mitsubishi equipment, and we're an authorized Comfortmaker dealer. Every job comes with a 1-year labor warranty.

Signs your mini-split needs attention

  • No heating or cooling

    The indoor unit runs but the air isn't warm or cool.

  • Indoor unit dripping

    Water running down the wall or pooling under the unit.

  • Weak airflow

    Little air moves from the indoor unit even on high.

    Frost builds on the outdoor coil and doesn't clear.

  • Odd smells

    A musty or stale smell from the indoor unit when it runs.
