OVER A DECADE OF EXPERIENCE
From keeping your home cool during humid Pennsylvania summers to ensuring reliable heat all winter long, 717 Mechanical LLC is Palmyra's trusted provider for air conditioning, heating, and water heater services. Our experienced technicians deliver professional installations, thorough maintenance, and prompt repairs that help lower energy bills and extend the life of your equipment.
Is your air conditioner over 10 years old, running constantly, or driving up your electric bills? Upgrading to a new high-efficiency central AC system can dramatically improve your home's comfort. We install top-rated air conditioning systems sized correctly for Palmyra homes of every layout.
Whether it's a refrigerant leak, frozen evaporator coil, or a compressor that won't start, our technicians diagnose and repair all makes and models of central air conditioners. We also offer pre-season AC tune-ups so your system is ready before the heat arrives.
Heat pumps deliver both cooling and heating from a single system, making them a smart choice for Palmyra homeowners looking to reduce energy costs. We install both ducted and ductless mini-split heat pumps tailored to your home's needs.
If your heat pump isn't cooling efficiently or struggles to switch between modes, our team will troubleshoot the issue and restore peak performance. Routine maintenance keeps your heat pump running smoothly year after year.
When your furnace can no longer keep up with Lebanon County winters, it may be time for a high-efficiency replacement. We install gas and electric furnaces that deliver consistent warmth and measurable energy savings for Palmyra homeowners.
From pilot light failures to blower motor issues, we repair all furnace types quickly and affordably. Our annual furnace maintenance program catches small problems before they become expensive emergencies.
Many of Palmyra's established homes rely on boilers for heat. We install and repair gas, oil, and electric boilers, helping homeowners maintain even, radiant heat at a lower operating cost.
Need to add cooling or heating to an addition, sunroom, or converted attic? Ductless mini-splits provide zone-controlled comfort without the need for ductwork — ideal for Palmyra homes that weren't originally built with central air.
Our certified technicians service all major mini-split brands, handling everything from drainage issues to compressor failures. Regular cleaning and maintenance keeps your system efficient and extends its lifespan.
Running out of hot water is more than an inconvenience — it disrupts your daily routine. We install Bradford White tank water heaters and Navien & NTI tankless water heaters, giving Palmyra homeowners access to endless hot water, improved efficiency, and lower monthly energy costs.
Whether your tank unit is leaking, producing lukewarm water, or making unusual sounds, we provide expert water heater diagnostics and repairs. Annual flushing and maintenance prevents sediment buildup and extends the life of your system.
Palmyra homeowners spend a significant amount of time indoors — especially during allergy season and the coldest months. Improve the air your family breathes with our indoor air quality solutions:
We install and service Honeywell air filtration systems and Aprilaire humidifiers, providing cleaner, healthier indoor air for your Palmyra home.

Visit Service Finance Explore PowerPayPalmyra is well within our regular service area, and we can typically schedule a same-day or next-day AC repair appointment depending on availability. For emergency situations — like a complete system failure during a heat wave — we offer priority scheduling to get a technician to your home as fast as possible. Contact us or call 717-468-9567 to get on the schedule.
We recommend scheduling your annual AC tune-up in late March through May, before the summer rush. Pre-season maintenance allows our technicians to identify worn parts, low refrigerant levels, or dirty coils before they cause a breakdown when you need cooling the most. Palmyra homeowners who schedule early often get more flexible appointment times and can take advantage of our seasonal maintenance specials.
It depends on your home and your goals. A central air conditioner paired with a gas furnace is a proven combination for Pennsylvania's climate. However, a heat pump provides both cooling and heating from one system, which can lower energy costs — especially if you're replacing an aging furnace at the same time. Many newer homes in Palmyra's growing developments are great candidates for heat pumps. We'll evaluate your home's size, insulation, and ductwork to recommend the best fit.
If you notice any of these symptoms, call us right away. Catching compressor problems early can sometimes save you from a full system replacement.
Absolutely. 717 Mechanical LLC is based in Marietta, PA, and we serve homeowners across both Lancaster and Lebanon Counties. Palmyra sits right near the county line, and we regularly service homes throughout the area — including Hershey, Annville, Cleona, Elizabethtown, Mount Joy, Lititz, Columbia, and Wrightsville. Whether you're in Lancaster County or Lebanon County, we've got you covered.
Yes. We understand that a new air conditioning system is a significant investment. That's why we offer flexible financing options with affordable monthly payments for qualified homeowners. Financing is available for AC installations, heat pump systems, furnace replacements, and water heater upgrades. We'll explain all available options during your in-home consultation so you can make the best decision for your budget.
A traditional tank water heater stores 40-50 gallons of pre-heated water in a tank, ready to use. They have a lower upfront cost and are straightforward to replace. A tankless water heater heats water on demand as it flows through the unit — meaning you never run out of hot water. Tankless units are more energy-efficient, take up less space, and typically last longer, but they have a higher initial installation cost. We install Bradford White tank models and Navien and NTI tankless systems, and we'll help you weigh the pros and cons based on your household's hot water usage.
We know that HVAC emergencies don't follow a schedule. If your AC fails on a weekend or your furnace stops heating on a frigid night, call us at 717-468-9567. We offer emergency service and will work to get a technician to your Palmyra home as quickly as possible. Our goal is to restore your comfort the same day whenever the situation allows.
