We couldn't be more pleased with our G-Force experience!! Corey came to our home to analyze the units we had and in the process, discovered that we did not have enough cold air returns -- so in addition to proposing a new furnace and a/c for our home, additional duct work was done to allow our new units to work more efficiently. Russ and Steve were very efficient and careful when removing the old units and installing the new units. They were very thorough and tidy. After a couple of weeks, we discovered a small issue that required a callback and within 30 minutes of calling, Jimmy arrived to resolve the issue. We are confident that we now have units that will give us comfort for many years to come. If you desire a fair, honest and efficient HVAC contractor, Getzschman is the BEST!!! You won't be sorry you called Getzschman.
