We had a new Carrier HVAC system installed on July 4, 2018 and we could not be happier with the results. Our house is over 4700 sq. ft. and we needed to make sure the 2 units would be efficient upstairs and down. The job was completed in 2 days including new duct work in the attic. Ron McMaster and his crew of 8 people performed the work professionally and took care to leave the house without need for cleaning or repairs to walls, floors, etc. We knew we wanted to go with Carrier units and we researched 4 Carrier dealers near us. The need to have a experienced installer is more critical than the equipment you purchase. McMaster Heating and Air Conditioning has won awards as a top Carrier distributor for many many years. They did a complete survey of our needs and proposed a system to replace the units we had. Our new system blows colder and is quieter and more efficient. It was a wise choice.
