Case Studies

THE PROBLEM: An approximately 19-year-old Mitsubishi Electric mini-split serving a sunroom was still operating but had accumulated significant dirt and debris after years without professional cleaning or routine maintenance. The customer wanted to understand the equipment’s condition and decide whether cleaning or replacement made more sense.

THE SOLUTION: Professional cleaning was explored first, with a return visit scheduled to thoroughly clean the indoor unit. After considering the system’s age, condition, and available warranty options, the customer chose a new Mitsubishi Electric mini-split for a fresh start with sunroom comfort.

THE PROBLEM: The customer’s existing 80% efficient boiler was still working, but the chimney it used for venting had begun to deteriorate. A costly chimney repair estimate prompted the customer to compare the complete cost of a conventional boiler replacement with a high-efficiency upgrade.

THE PROBLEM: A customer’s aging gas-fired steam boiler was approaching the point where replacement made more sense than continued reliance on older equipment. The home needed a new boiler properly matched to its existing radiators, along with a replacement for its electric water heater.

THE SOLUTION: A radiator-by-radiator survey established the connected steam load before a new gas-fired steam boiler was selected and installed. The project replaced the aging boiler with new equipment and manufacturer-backed warranty coverage while converting domestic hot water from electric to gas.

THE PROBLEM: A Langhorne, PA homeowner was ready to replace an aging oil-heating system and move away from oil deliveries. Converting to natural gas required proper furnace sizing, an evaluation of the existing ductwork, and confirmation that the home’s gas service could support the additional heating equipment.

THE SOLUTION: A new Trane natural-gas furnace replaced the existing oil equipment after heating-load calculations, PECO gas-capacity verification, and the required permitting and approvals were completed. Removing the oil tank eliminated the need for future heating-oil deliveries, while the home’s existing ductwork provides a starting point for adding central air conditioning in the future.

THE PROBLEM: A family relied on window air conditioners to cool their split-level home. The units were noisy, comfort varied from room to room, and the kitchen windows couldn’t accommodate a traditional window AC. The family wanted a quieter way to make the spaces they used most comfortable.

THE SOLUTION: A three-to-one Mitsubishi Electric mini-split system with standard heat pump technology gave the family independent heating and cooling in three key areas: the lower-level sitting room, the open living area, and the kitchen. They chose to address those spaces first and leave the bedrooms for a future phase that could be planned around their home and budget.

THE PROBLEM: A historic home built in several stages had never had air-conditioning. Conventional ductwork would have required significant alterations, while a newer addition lacked the attic space needed to connect with the rest of the home.

THE SOLUTION: A customized system combined high-velocity air-conditioning in the original home with a two-zone Mitsubishi Electric mini-split system in the newer addition. The design provided efficient, targeted cooling while protecting the home’s historic character.

THE PROBLEM: After nearly 35 years of living with one of their bedroom's that was too hot in the summer and too cold in the winter, the homeowners needed a better solution as their family continued to grow. Because the bedroom was located far from the central HVAC system in a multi-level split-level home, it did not receive enough airflow to remain consistently comfortable.

THE SOLUTION: A single-zone ductless mini-split gave the bedroom its own dedicated source of heating and cooling. The homeowners can now control the room’s temperature independently without replacing the central HVAC system or making extensive modifications to the home’s existing ductwork.

THE PROBLEM: An aging window air conditioner had failed, leaving the homeowners looking for a more permanent cooling solution. Their biggest concerns were noise and comfort, as the old window unit could be loud enough to interfere with conversations when family and friends were visiting. 

THE PROBLEM: During the middle of the summer heat, an 18-year-old HVAC system stopped providing air conditioning in a Doylestown, PA home, leaving the homeowner without reliable cooling when it was needed most. The existing Carrier heating and cooling system had served the home well for nearly two decades, but with the air conditioner no longer keeping the house comfortable, it was time to determine whether another repair made sense or if replacing the aging HVAC system was the better long-term solution.

PROBLEM: Homeowners in Pennsauken, NJ wanted a better cooling system, but their home did not have ductwork. 

SOLUTION: Installing a seven-zone Mitsubishi ductless air conditioning mini split system. It uses a heat pump and seven air handlers to treat the first floor, bedrooms, and office.
