  • out of 5 stars

    We recently purchased a 4,000 sq ft home in Novato,CA. Both the gas heating and air conditioning systems needed to be replaced and large sections of duct work needed to be replaced as well. We engaged Contra Costa HVAC to install (2) Lennox Elite EL296V gas furnaces and (2) Lennox 16 SEER Condensers. The installation team consisted of three very hard working, knowledgeable and highly skilled field service technicians. Alex was our team lead. Over a three day period, they disassembled and removed the old units and installed and tested the new systems. The quality of the workmanship really shows in the welds, alignments, configuration and aesthetic appearance of the wrapped and insulated units. We were pleased with the consideration given in adjusting air-flow to provide comfortable heat and cooling throughout the house. We would recommend the services of Contra Costa HVAC to others without reservations.
