Since 2012 we have handled installation, repair, and maintenance of furnaces, air conditioners, heat pumps, boilers, water heaters, and indoor air quality systems for homes in Mount Joy Borough, Florin, Rapho Township, and the Donegal area along the Route 230 and Route 283 corridor.
Mount Joy is a mix of older in-town homes along Main Street, newer developments on the edges of the borough, and manufactured-home communities in the surrounding townships, and each one calls for different equipment.

LOCALLY-OWNED & COMMUNITY FOCUSED
OVER A DECADE OF EXPERIENCE
Mount Joy is the next town over from our Marietta shop, which makes it one of the places we work most often. Whether it is keeping your home comfortable in every season or making sure you always have hot water, 717 Mechanical LLC covers heating, cooling, and water heater service for the whole house, from the borough and Florin out to the farms and manufactured-home communities of Rapho Township and the Donegal area. One local team handles the repairs, installations, and maintenance, so problems get traced to the actual cause instead of patched around.
If your air conditioner is outdated or inefficient, upgrading to a modern, energy-efficient system can significantly reduce energy costs and improve comfort. We install central air conditioners, ducted heat pumps, and ductless mini-splits, ensuring the perfect fit for your home’s needs.
Is your AC blowing warm air, making strange noises, or not turning on? Our technicians handle central air conditioner repair on all major brands, diagnose the fault before quoting the fix, and carry common parts on the truck so most Mount Joy repairs finish in one visit.
Regular AC tune-ups extend system lifespan, prevent costly breakdowns, and improve energy efficiency. Our comprehensive maintenance plans ensure your AC runs smoothly all summer.
If your furnace is more than 15 years old, inefficient, or costly to repair, upgrading to a new high-efficiency furnace can improve comfort and energy savings. Our furnace installation team replaces gas and electric furnaces with a model sized to your Mount Joy home's square footage and duct layout.
From ignition problems to airflow issues, we repair gas and electric furnaces of every age and brand. A fall furnace tune-up before the first cold snap helps prevent breakdowns and confirm safe operation.
We install, repair, and maintain high-efficiency boilers to provide consistent heating and lower energy costs. Our team services gas, oil, and electric boilers.
Heat pumps provide year-round heating and cooling on one system, and many of the newer developments around Mount Joy were built all-electric with one. Our ducted heat pump installation service replaces a tired builder-grade unit with a properly sized high-efficiency model; for rooms the ducts never reached, we install ductless mini-splits.
If your heat pump is icing up, running constantly, or failing to switch modes, our technicians diagnose and repair heat pumps of all major brands. Seasonal maintenance keeps the system efficient and reliable through both a Lancaster County summer and winter.
We install Bradford White tank water heaters and Navien tankless water heaters, sized to the number of bathrooms and people in your Mount Joy home for reliable hot water and lower energy costs.
From sediment buildup to heating element failures, we provide expert water heater repairs and annual maintenance to extend system lifespan and improve performance.
A Bradford White tank water heater is the straightforward replacement for most Mount Joy homes: it drops into the same spot, uses the same venting and connections, and costs less up front. It is the right call for a household with steady hot-water use and a basement or utility room with space for the tank.
A Navien tankless water heater heats water on demand, so a busy household never runs out, and it frees up floor space in a tight mechanical room. It needs adequate gas supply and side-wall venting, and Lancaster County's hard water means periodic descaling, which we handle as part of tankless maintenance. We will tell you honestly which option fits your house and your budget.
Mount Joy and Rapho Township have a number of manufactured-home communities, and those homes need equipment built for them: a furnace rated for manufactured housing, ductwork that fits a crawlspace or belly board, and outdoor units set on a proper pad. Our mobile & modular home HVAC service covers furnace, air conditioner, and heat pump installation, repair, and maintenance for these homes, and for the many that use a single rooftop or ground-set unit for both heating and cooling, we also handle package unit installation and replacement. Same parts on the truck, same upfront pricing, same technicians.
