Energy-Efficient Heating & Cooling Systems For Server Rooms, Room Additions, Detached Offices, Garages & More

We have over 20 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.

Regular Preventative Maintenance To Keep Your Ductless Mini-Split System Performing at Its Best

Though mini-split systems are well known for their cost-effectiveness and high efficiency ratings, they also require regular maintenance to remain operating in optimal condition. For example, it's extremely important to flush and clean the coils and blower wheels on an annual basis to prevent build-up on essential components, which could lead to decreased function and poor indoor air quality. McMaster Heating & Air offers thorough maintenance services specifically designed to keep your system performing at its best. Our preventative maintenance service for ductless mini-split systems includes inspecting, cleaning, and testing your system's safety controls, moving parts, thermostat, and electrical connections. If we notice any problems, we will let you know immediately and recommend a reliable, cost-effective repair solution.
