Efficiency came out to service our old heat pump, which had died. We decided to replace it with a new AC unit and they credited the cost of the service call toward the installation. We also decided to have them install a new water heater to replace an old corroded one. The technician (Doug) and salesperson (Jason) were both professional, responsive, and good to work with. The only slight snag was that the plumber had to reschedule the water heater installation to another day (they were going to do all the work on the same day). But overall, we’re very happy with the new AC and water heater and would definitely recommend Efficiency.
