Energy-Efficient Heating & Cooling Systems For Server Rooms, Room Additions, Detached Offices, Garages & More
We have over 40 years of experience designing, installing, repairing, and servicing energy-efficient ductless mini-split systems for Orange County homes and businesses. Because ductless mini-splits deliver heating and cooling directly to an intended area and offer separate temperature control, they are a popular HVAC solution for server rooms, multi-tenant buildings, and other commercial and industrial applications. They are also ideal for use in residential spaces where ductwork is difficult to install, such as detached offices, garages, sunrooms, and room additions. For Carrier mini-split system installations, we offer their 10-year limited parts warranty, along with a five-year labor warranty. When you have your mini-split system installed by McMaster Heating & Air Conditioning, we also provide an AHRI Efficiency Certificate and exact efficiency rating for your specific combination of HVAC equipment.
