A ductless mini-split heats and cools one room at a time, with no ductwork to run and no wasted air on the rooms nobody is using. 717 Mechanical LLC handles every stage of that system: installation & replacement, repair, and annual cleaning and maintenance.
With over 14 years of experience, our technicians size, place, and commission ductless systems for homeowners in Marietta, PA and across Lancaster County. We install Samsung and Bosch ductless equipment, and we service most major mini-split brands whether or not we were the ones who put it on the wall.
Ductless is not the right answer for every house, and we will tell you when it is not. What you get from us is a straight read on whether a mini-split, a repair to the system you already own, or a different piece of equipment is the better move.
Licensed & Insured
Room-By-Room Zoning
14+ Years Experience
Every ductless job starts with a look at the actual space: how it is built, how it is used, and what it is doing wrong today. Pick the service that fits your situation, or call us and we'll point you in the right direction.
New Systems & Additions
Single-zone and multi-zone Samsung and Bosch systems, sized to the room instead of the sales sheet, with line sets and condensate runs planned before we drill anything.
Mini-Split InstallationFast, Honest Diagnosis
Blinking error lights, water dripping from an indoor head, ice on the outdoor unit, or a zone that stopped responding: we find the real cause, with priority scheduling for urgent repairs.
Mini-Split RepairSeasonal Maintenance
Deep cleaning of the indoor coil and blower wheel, condensate line clearing, refrigerant and electrical checks. Available as a one-time visit or as part of our maintenance plans.
Maintenance & Tune-UpsNot sure where to start? Here's how we'd think about it:
A zone stopped heating or cooling, or the head is leaking water? Start with mini-split repair. Most ductless failures announce themselves with a flashing indicator code on the indoor unit, and that code tells us a lot before we arrive. We offer priority scheduling for urgent repairs.
Adding a sunroom, finishing a garage, or fighting one room that's never comfortable? That's the classic case for ductless installation - no ducts to run, no soffits to build, and the new space gets its own thermostat. Financing is available on new systems.
Already have ductwork and want one system for the whole house? A ducted heat pump gives you the same efficient electric heating and cooling through the ducts you already own, and it is usually the better fit when the whole home needs replacing at once.
Buying ductless mainly for allergies or dust? Mini-splits filter the air in the rooms they serve, which helps, but they only treat those rooms. If the goal is cleaner air everywhere, look at whole-home indoor air quality options instead.
System running fine and you'd like to keep it that way? Ductless heads collect dust faster than ducted equipment because the coil sits in your living space. An annual cleaning through our HVAC maintenance plans is the cheapest thing you can do for a mini-split.
