the phone by himself and be able to come by the next hour. Fixed the problem and also check and

Our home has dual HVAC units. The electric-only unit in our attic has given us issues for years. Rob Will of Will Air inexpensively serviced the unit and babied it along so that we were able to get as much life out of it as possible. Once it was no longer economically smart to keep repairing the unit, Rob recommended a new unit that was affordable, energy efficient and more properly sized for our square footage. The new unit works like a charm and has not needed any service since installation. Rob and his staff show up quickly, and stay until the job is done. Sherry is always friendly and pleasant on the phones and is a pleasure to work with. I will continue to use Will Air for all of my HVAC needs and will recommend them to anyone who needs a trusted HVAC repair company.
