How MGM Mechanical Helped a Church in Mifflintown, PA Add Year-Round Comfort Without Sacrificing Its Character
When churches and older commercial buildings in Central Pennsylvania need HVAC upgrades, the best solution is not always the most obvious one. In many cases, the project calls for a system that improves comfort and energy performance while still respecting the building’s architecture, layout, and long-term use.
That was exactly the challenge at a church in Mifflintown, PA. The sanctuary did not have air conditioning, and the building was being heated with an oil boiler. The client needed a practical way to add cooling, improve heating performance, and preserve the visual appeal of the sanctuary at the same time.
For this project, MGM Mechanical designed and installed a ducted Mitsubishi heat pump solution that delivered both heating and cooling to the sanctuary without creating unnecessary visual disruption. The result was a cleaner, more appropriate fit for the building and a better comfort experience for the congregation.
The Challenge: Comfort, Aesthetics, and Building Limitations
The church’s sanctuary featured beautiful stained glass windows and a traditional interior that made a standard wall-mounted ductless system less desirable. While mini-splits can be an excellent choice in many commercial and institutional applications, this building required a different approach.
Installing wall heads would have required drilling and placement decisions that could have affected the appearance of the sanctuary and introduced avoidable risk around the stained glass and exterior building surfaces. Instead of forcing a system that did not fit the structure, MGM Mechanical evaluated the building’s layout and designed a more suitable ducted option.
The Solution: Mitsubishi Hyper-Heating Ducted Heat Pumps
MGM Mechanical installed two 4-ton Mitsubishi hyper-heating ducted heat pump systems for the church. Two duct packages were installed in the attic, allowing conditioned air to be distributed into the sanctuary through ceiling supply vents.
This design gave the church a way to add air conditioning while also upgrading year-round comfort with modern heat pump technology. According to the U.S. Department of Energy, heat pumps can provide efficient heating and cooling by transferring heat rather than generating it through combustion, which is one reason they are increasingly considered for all-climate applications. Mitsubishi also positions its ducted and hyper-heating systems as a strong fit for projects that need all-electric comfort, quiet operation, and design flexibility.
How the Return Air Design Helped Preserve the Sanctuary
One of the most thoughtful parts of this installation was the return air strategy. MGM Mechanical used the front vestibule as the return path and modified the swinging doors with custom decorative transfer grilles. Air is pulled from the sanctuary through those transfer grilles and into return grilles placed in the vestibule ceiling.
That approach helped maintain the visual integrity of the main worship space while still giving the new system the airflow path it needed to perform correctly. For churches and other specialty buildings, details like return placement, grille design, and attic duct routing often make the difference between a system that merely fits and one that genuinely works with the building.
Why This Project Matters for Churches and Older Buildings in Juniata County
Many churches, community buildings, and older commercial properties throughout Juniata County and Central PA face the same problem: they need better heating and cooling, but they also want to avoid solutions that feel out of place or require major interior compromises.
This project in Mifflintown shows that there is often a middle ground between doing nothing and choosing the fastest installation method. With the right planning, a contractor can design a system that respects the structure, protects architectural details, and still delivers dependable comfort.
For organizations weighing boiler replacement, adding cooling to a sanctuary, or upgrading from older fuel-based heating equipment, the design process matters as much as the equipment itself. A building like this needs more than a generic proposal. It needs a contractor who understands both HVAC performance and real-world installation constraints.
