A package unit does the work of a furnace and an air conditioner from a single cabinet outside your home. 717 Mechanical LLC covers all of it: installation & replacement, repair, and seasonal maintenance.
Because there is no indoor air handler or furnace, packaged systems are the practical choice for homes without a basement, attic, or mechanical closet to spare. That makes them especially common on modular and manufactured homes around Lancaster County, and on ranch homes built on a slab. We work on gas/electric packaged units, packaged heat pumps, and packaged air conditioners with electric heat.
With over 14 years of experience in Marietta, PA and the surrounding towns, our technicians know how these units fail: rusted cabinets, sealed duct connections that come loose, and blowers packed with debris after a season outdoors. You get a straight answer about what your system needs, not a sales pitch.
Licensed & Insured
Modular & Mobile Home Ready
14+ Years Experience
One cabinet handles your heat and your air conditioning, so a package unit problem affects the whole house in both seasons. Pick the service that matches your situation, or call and we'll help you sort it out.
New Systems & Replacements
Correctly sized all-in-one systems set on a level pad or roof curb, with the duct connections sealed and the electrical and gas work done to code. Financing is available on new installs.
Package Unit InstallationFast, Honest Diagnosis
No heat, no cool air, tripping breakers, or a unit that runs constantly: we find the actual fault and repair it, with priority scheduling for urgent repairs.
Package Unit RepairSeasonal Maintenance
Spring and fall visits that clear out debris, clean the coils, check the heat exchanger and controls, and catch worn parts before the cabinet quits on you mid-season.
Maintenance & Tune-UpsNot sure where to start? Here's how we'd think about it:
Unit running but the house isn't heating or cooling? Start with package unit repair. If your home is unsafe to stay in, our emergency HVAC service page explains how we handle urgent calls - we offer priority scheduling for urgent repairs.
Cabinet rusting out, or the unit past 12 to 15 years? Look at installation & replacement. Outdoor cabinets weather faster than indoor equipment, and we'll tell you honestly how much life is left. Financing is available on new systems.
Live in a modular or mobile home? Package units are the standard setup on those homes, and the duct and equipment requirements are different. See our mobile & modular home HVAC page for what we check on those jobs.
System working fine right now? Keep it that way with twice-yearly service through our HVAC maintenance plans, so the heating side is checked before winter and the cooling side before summer.
