Frank of Tedco responded to my request immediately and arrived that night from another job. He serviced my central air up and running. Very happy with their quick response and service.- Robert G.

Frank responded quickly and courteously. He solved my problem in an hour after investigating my 18-year-old cooling system: clogged filter and no freon. I'm sure other companies would have told me the unit needed to be replaced. Now my AC runs ice cold.- Drue S.
