717 Mechanical LLC is a family-owned heating and cooling company based at 2710 Maytown Rd in Marietta, PA. Since 2012, we have installed, repaired, and maintained HVAC systems for homeowners across Lancaster County, from Marietta and Mount Joy to Lancaster, Lititz, and Hershey.
We are not a franchise and we do not run our business like one. When you call us, you reach a local company that answers to its neighbors. Our work is backed by a 5-star Google rating earned one job at a time, over more than a decade of service in the same communities we started in.
Whether you need a repair, a full system replacement, or a seasonal tune-up, the process starts the same way: we listen, we diagnose, and we give you a straight answer with the price up front.
Lancaster County weather asks a lot of HVAC equipment. Summers are hot and humid, winters are cold, and the spring and fall swings in between mean most homes lean on both their heating and cooling systems hard every year. That is the environment we have worked in since day one, and it shapes how we size equipment, what we recommend, and how we schedule maintenance for our customers.

Upfront, Honest Pricing
We handle the four systems that keep a Lancaster County home comfortable year-round:
Repair and replacement are only half the picture. We also run maintenance plans with seasonal tune-ups, because the cheapest repair is the one a spring or fall inspection prevents. And when a system does reach the end of its life, we walk you through the options at every price point rather than handing you a single quote.
We are factory-trained on the equipment we sell and we service all major brands. Our installation lineup includes Armstrong Air, AirEase, American Standard, Samsung, Aprilaire, Honeywell, Bosch, RGF, Bradford White, Navien, and NTI. That range covers furnaces, air conditioners, heat pumps, ductless systems, thermostats and controls, air quality equipment, and tank and tankless water heaters, which lets us match the equipment to your home and budget instead of pushing a single product line.
Fourteen years in the same county means our reputation rides on every job. Here is what you can expect when you hire us:
We also think a homeowner should understand the work being done in their own house. Our technicians explain what failed, why it failed, and what your options are in plain language. If a fix can wait until fall, we will tell you that too. The goal is a customer who calls us back in five years, not a one-time invoice.
Our shop sits in Marietta, PA, and most of our work stays close to home. We serve Lancaster, Hershey, Mount Joy, and the surrounding Lancaster County communities, including Lititz, Palmyra, Elizabethtown, Columbia, and Wrightsville. Each of those areas has its own service page with details on what we do there, and because we keep our service area tight, drive times stay short and scheduling stays realistic.

Call (717) 468-9567HVAC is a relationship business. The company that installs your system should be the one that maintains it, answers the phone when something goes wrong, and remembers your equipment's history. That is the role we have filled for Lancaster County homeowners since 2012.
A heating or cooling system is one of the largest mechanical investments in a home, and it only performs as well as the company standing behind it. We size it correctly the first time, maintain it season after season, and repair it with the same care whether the job is a fifteen-minute fix or a full changeout. That consistency is what a 5-star rating actually measures.
