Heat Pumps: Orange County’s Best Choice for
Year-Round Indoor Comfort

Heat pumps are an excellent HVAC option for Orange County’s homes and businesses. A heat pump can be ducted (central air) or ductless (also known as mini-splits) and provide both heating and cooling. Unlike traditional heating and cooling systems that generate heat or cold air, heat pumps work by transferring heat between indoor and outdoor environments. This unique technology works particularly well in mild climates like ours. As a result, heat pumps are considerably more energy-efficient and environmentally friendly than HVAC systems with separate air conditioners and furnaces.

An Eco-Friendly & Energy-Efficient
Heating and Air Conditioning Solution

At McMaster, we have over 40 years of experience designing, installing, repairing, and servicing ducted and ductless heat pump systems for Orange County homes and businesses. Because heat pumps are one of the most energy-efficient and eco-friendly options, they often qualify for rebates and tax credits. When designed properly, heat pumps can meet the demands of nearly any residential or commercial space, from room additions, server rooms, and garage conversions to entire homes, multi-unit housing, hotels, restaurants, and commercial buildings.

Carrier backs their heat pumps with a one-year 100% satisfaction guarantee when installed by a Carrier Factory Authorized Dealer. They also offer a limited parts manufacturer warranty for ten years. When you have your heat pump system installed by McMaster Heating & Air Conditioning, you’ll also get an AHRI Efficiency Certificate confirming the exact efficiency rating for your specific HVAC system.

Enjoy Enhanced Whole-Home Comfort from
Packaged Hybrid Heat Systems

Packaged hybrid heat systems represent an innovative and energy-efficient approach to heating and cooling. These systems combine the benefits of both traditional furnaces and heat pumps, offering versatility and cost savings. During the colder months, the furnace component efficiently produces heat, while in milder weather, the heat pump takes over, drawing heat from the outside air and delivering it indoors. This seamless transition ensures optimal comfort and energy efficiency year-round, reducing energy consumption and lowering utility bills. Packaged hybrid heat systems are an excellent choice for those looking to minimize their environmental footprint while enjoying consistent and reliable indoor climate control.

Customer Reviews

Very pleased with the service and the products

Ron was super-knowledgeable when he visited the house and checked out what was needed. I wanted a heat pump, which can sometimes be tricky, but his team has installed lots of them and knew exactly what to do...

Very pleased with the service and the products, and would recommend to anyone.

They had great prices and did a great job.

James, Mike, and Anthony at McMaster really helped me out by installing a brand new Infinity Carrier Heat Pump in town home. The installation was rather difficult since my old unit was a hydronic system in a dropped ceiling. They removed the old unit and installed the new fan coil in closet. They had great prices and did a great job.
