A valid concern when upgrading historically significant buildings is how to extend heating and cooling while maintaining the structural integrity and architectural significance of the building. Making the design modifications necessary to include ductwork for central conditioning is prohibited on historical structures. Even if the structure is not protected for preservation, the costs associated with the modifications to add a central conditioning system could well exceed budgetary constraints.
J. Edington Burroughs House
Ownership of the J. Edington Burroughs House in Flint, Michigan was taken by the National Center for Community Education (NCCE) in 2002. The J. Edington Burroughs House was built in 1928, so for historical preservation, the heating and cooling demands presented a unique problem.
Obviously, to maintain the structural and architectural integrity of the house, central air conditioning was eliminated as a solution. Ultimately, Mitsubishi Mr. Slim Split System Heat Pumps were installed. The units allowed the NCCE executive committee to maintain the historical significance of the building while offering heating and cooling for every room in the house.
Because the compressors are outside the building, the air conditioning is extremely quiet inside the building. With just a 3-inch to 4-inch diameter hole required to connect the inside air distribution to the outside compressor, there is no need for structural alterations. Additionally, the windows are not compromised with individual window units.
Budgetary constraints were maintained as installation is simplified and operational costs are minimal. If you have a historically preserved building, private or commercial, perhaps the answer to your air conditioning and heating dilemma is a Seattle Mitsubishi Split System Ductless Heat Pump.
