Landisville sits in East Hempfield Township off Route 283, roughly halfway between Lancaster and Mount Joy, and only minutes from the 717 Mechanical LLC shop in Marietta. For homeowners in the 17538 area, that means heating and cooling help comes from a neighbor rather than a dispatcher two towns away.
We are a family owned company that has worked on Lancaster County homes since 2012, covering air conditioning, furnaces, heat pumps, water heaters, and indoor air quality. Estimates are free on new equipment, repairs are quoted up front, and we provide priority scheduling for urgent repairs when a system fails at the worst possible time.
Being this close changes the experience of hiring a contractor. A technician who is fifteen minutes out can return the same week if a follow-up is needed, a quote can be walked through at your kitchen table instead of over the phone, and the company standing behind the warranty is one you can drive past on Maytown Road. That is the kind of HVAC relationship Landisville homeowners get with us.
Reach us at (717) 468-9567 to schedule service anywhere in Landisville or East Hempfield Township.

OVER A DECADE OF EXPERIENCE
The air conditioner, the furnace, the water heater, and the air you breathe all run through the same mechanical backbone of the house. 717 Mechanical LLC services that whole backbone, so a single trusted number handles whatever breaks, wears out, or needs an upgrade.
Short cycling, frozen coils, breakers that will not stay on, a unit that runs all day without dropping the temperature: these are diagnosable problems with specific fixes. Our air conditioning repair service covers every major brand in Landisville, and we never quote a fix until we know the actual cause.
An oversized air conditioner short-cycles and leaves the house clammy; an undersized one never catches up. Our installation process starts with a proper load calculation, then matches your home to Armstrong Air, AirEase, or American Standard equipment that fits the way you actually live.
Get a professional AC tune-up in spring and the system meets summer with tested electrical components, clean coils, and a verified refrigerant charge. It is the difference between cruising through July and sweating out a repair wait.
The best air conditioner on the market cannot overcome leaky or undersized ducts. When a Landisville home has a hot upstairs, weak airflow in the far bedrooms, or a system that runs constantly, we look at the duct system as well as the equipment, because fixing the right problem is cheaper than replacing the wrong component.
A furnace that cannot hold temperature through a Lancaster County cold snap needs attention fast. We troubleshoot and repair gas and electric furnaces of any brand, and when the repair math stops working we install high-efficiency replacements with honest guidance on what your house actually needs.
Schedule a heating tune-up before the first hard frost. We inspect the heat exchanger, test ignition and safety controls, and verify gas pressure so the system runs safely and efficiently through the season.
For homes off Route 283 looking at all-electric comfort, modern heat pumps deliver heating and cooling from one outdoor unit. We install ducted heat pumps, set up ductless mini-splits for additions and bonus rooms, and keep boiler-heated homes warm too.
Any fuel-burning furnace or boiler deserves a yearly safety inspection. A cracked heat exchanger or blocked flue can push combustion gases into living space, and the early signs are invisible without instruments. Our heating tune-ups include the combustion and venting checks that protect the people in the house, not just the equipment in the basement.
Rumbling sounds, rusty water, or a puddle under the tank are the classic warning signs. We repair what can be repaired and replace what cannot, installing Bradford White tanks sized to keep up with your family's showers, laundry, and dishes.
A tankless unit heats water only when a tap opens, so the supply never runs out mid-shower. We install and service Navien and NTI systems for Landisville homeowners ready to retire the storage tank. Sizing matters with tankless: the unit has to match your gas supply and your peak demand, and we calculate both before recommending a model.
Pollen season around the farm fields and tight, well-sealed newer construction can both leave indoor air worse than the air outside. Our options include:
Almost every January no-heat call and August no-cooling call starts as a worn part that nobody noticed. Joining our HVAC maintenance plan means a technician notices: cooling gets inspected in spring, heating in fall, on a schedule we track for you. You get the findings in plain language after each visit, including what is fine, what is wearing, and what can safely wait.
Replacing a furnace or air conditioner is one of the larger checks a homeowner writes. Our financing page explains the options available to qualifying Landisville homeowners who would rather pay monthly than all at once. Ask for the financing breakdown with your estimate and we will include it, no pressure attached.
Because Landisville is so close to our shop, urgent calls here are among the easiest for us to reach. We offer priority scheduling for urgent repairs, so a house with no heat or no cooling moves to the top of the day's route. When you call, have the brand and rough age of the system handy if you can; it helps us load the right parts before the truck leaves Marietta.
