Millersville sits in southwestern Lancaster County and is best known as the home of Millersville University. That gives the area an unusual housing mix: student rentals near campus, established borough homes, and suburban developments spreading through Manor Township. 717 Mechanical LLC keeps the heating and cooling working in all three.
We are a family-owned HVAC company based in Marietta, serving Lancaster County since 2012. Homeowners call us for AC repair, furnace and heat pump service, water heater replacement, and indoor air quality work; rental owners call us because we coordinate with tenants and document what we did and why.

OVER A DECADE OF EXPERIENCE
A landlord with a no-cool call from tenants needs a fast, documented fix. A family in a Manor Township development wants a quiet system and a lower electric bill. A longtime borough resident wants the boiler to make it one more winter. 717 Mechanical LLC handles each of those jobs every season, and each gets the solution that fits, not the one that pays best. Because we service furnaces, boilers, central air, heat pumps, mini splits, water heaters, and air quality equipment, there is no handing you off to a second contractor halfway through the job.
Whether the unit froze over, the compressor will not engage, or the thermostat reads one thing while the house feels another, our air conditioner repair service covers all major brands. We diagnose first, quote second, and repair only what actually failed.
When repair money would be better spent on replacement, we provide AC installation in Millersville with properly sized central air, heat pumps, or ductless equipment from Armstrong Air, AirEase, American Standard, Samsung, and Bosch. Every install gets a commissioning check before we leave.
Book an AC tune-up before graduation weekend traffic and the first heat wave arrive together. A clean, tested system uses less electricity and is far less likely to quit when it is working hardest.
Ductless mini splits earn their keep in Millersville: they cool converted attics and student apartments without ductwork, give each room its own control, and heat efficiently in winter. For rental owners, they are also simple to service unit by unit.
We service gas and electric furnaces across the borough and Manor Township, from quick igniter swaps to full replacements with high-efficiency equipment. If a furnace is unsafe or uneconomical to fix, we will show you the numbers and let you decide.
A furnace tune-up each fall checks the heat exchanger, cleans the burners, and run-tests the system. For rental properties, it doubles as documentation that the heat was verified before the lease season's coldest months.
We install and maintain ducted and ductless heat pumps, and we keep older gas, oil, and electric boilers running safely in the borough's longer-standing homes.
For most households and rentals, a Bradford White tank water heater is the dependable workhorse. We replace failed tanks, often the same week you call, and haul the old unit away.
Busy households that keep emptying the tank can step up to a Navien or NTI tankless unit that heats water on demand. We handle sizing, gas line review, installation, and the annual descaling that keeps tankless systems efficient.
A university town changes hands constantly. If you just bought your first house in the borough, we can walk the mechanical systems with you, explain what each piece of equipment is, how old it likely is, and what maintenance it actually needs, so the learning curve does not arrive as a January breakdown. If you manage rentals, we keep records of every visit, communicate directly with tenants when you want us to, and flag developing problems between turnovers instead of letting them surface mid-semester. Either way, you get one number to call and a history that follows the property, not the paperwork.
Allergy flare-ups, musty basement smells, and dry winter air are all problems your HVAC system can help solve with the right add-ons:
We install Honeywell filtration, Aprilaire humidity equipment, and RGF purification systems, matched to the size of your home rather than sold off a shelf.
Air quality matters even more in properties with high turnover. A rental that has hosted years of tenants, or a borough home that has spent decades collecting dust in its ductwork, often benefits from a filtration upgrade more than any other single improvement. If anyone in the house deals with allergies or asthma, tell us when you call and we will start the conversation there.
A college town runs on word of mouth, and ours in Millersville comes from showing up, fixing it, and charging what we said we would.
Get a QuoteThe systems that survive fifteen Pennsylvania summers are the ones that get looked at every year. Our maintenance plans schedule a cooling check each spring and a heating check each fall, so nothing waits until it breaks. For rental owners, that twice-a-year rhythm also means a documented service history for every property, which pays for itself the first time a tenant dispute or an insurance question comes up.
Every repair is priced before it starts. When a full replacement is on the table, financing options let qualified homeowners spread the cost instead of postponing the fix through another brutal season.
A failed system in extreme weather goes to the top of our list. We offer priority scheduling for urgent repairs and same-day service when available, for homeowners and for landlords fielding tenant calls.

717 Mechanical LLC has handled Lancaster County heating and cooling since 2012. We install and service systems from Armstrong Air, AirEase, American Standard, Samsung, and Bosch, water heaters from Bradford White, Navien, and NTI, and indoor air quality equipment from Honeywell, Aprilaire, and RGF. Whatever is broken, we have probably fixed a hundred of them.
And if nothing is broken yet, even better. The least expensive HVAC work in Millersville is the maintenance visit that happens before the failure, the tune-up booked in April instead of the repair booked during the first ninety-degree week. Get on the schedule early, and summer becomes something you enjoy from a cool living room instead of a waiting list.
