Penfield, NY - This is a recent air conditioning job that D'Angelo's installed. We installed a Mitsubishi Mini-Split System. This is a pretty amazing system that is super-efficient and very quiet. This unit is used when a normal air conditioning system cannot be installed. A Mitsubishi system does not require a duct system. Because not duct system is needed this unit can be installed in a home that has a boiler system or even in a addition or a sun-porch. If you need or want air conditioning, you can trust the professionals at D'Angelo's Plumbing & Heating to get it done right.
