A heat pump is the one piece of equipment in your home that works in every season: it heats in January and cools in July, all from a single outdoor unit. 717 Mechanical LLC covers every side of that system: installation & replacement, repair, and year-round maintenance.
With over 14 years of experience, our technicians install and service heat pumps for homeowners in Marietta, PA and across Lancaster County. We install high-efficiency Bosch and Samsung heat pumps, and we repair and maintain most major brands no matter who put the system in.
Because a heat pump moves heat instead of burning fuel to make it, it runs entirely on electricity and does the work of a furnace and an air conditioner at once. We will walk you through what that actually means for your home, your ductwork, and your utility bills before you commit to anything.
Licensed & Insured
Heating & Cooling In One System
14+ Years Experience
A heat pump that is short on refrigerant or stuck in defrost costs you money in both seasons, not just one. Pick the service that fits where you are right now, or call and we will help you sort it out.
New Systems & Replacements
Properly sized Bosch and Samsung heat pumps installed by technicians who load-calculate the home first, plus straight talk on SEER2 and HSPF ratings and financing options.
Heat Pump InstallationFast, Honest Diagnosis
Blowing cool air in heating mode, iced-over outdoor coil, running constantly, or tripping the breaker: we find the actual fault and fix it, with priority scheduling for urgent repairs.
Heat Pump RepairYear-Round Servicing
Heat pumps run in all four seasons, so they earn two visits a year: one before heating season and one before cooling season. Both are covered by our maintenance plans.
Maintenance & Tune-UpsNot sure where to start? Here's how we'd think about it:
System running but the house isn't getting warm or cool? Start with heat pump repair. A heat pump that has lost its charge or has a stuck reversing valve will keep running and keep costing you. If your home is getting dangerously cold, see our emergency HVAC service page - we offer priority scheduling for urgent repairs.
Heat pump past 12 to 15 years, or facing a compressor bill? Look at installation & replacement. Efficiency gains on a heat pump show up in both seasons, so the math works out faster than it does on a heating-only system, and financing is available on new installs.
System working fine right now? Keep it there with twice-yearly service through our HVAC maintenance plans. Year-round run time is exactly why heat pumps reward regular attention.
No ductwork, or rooms the ducts never reach? A ductless mini-split is the same heat pump technology without the duct system - a good fit for additions, finished attics, garages, and older Lancaster County homes that were never ducted.
