My air conditioner was fixed by adding freon and fixing a circuit breaker. Serviceman seemed knowlegeable. But I was disappointed that he couldn't do some ductwork for me. Alvin Hollis, the original installers, had vented one of the outside ducts to outside air with no filter on it (and I wondered why my eyes always stung when I used my air conditioner.)I'll have to call another company to do the duct work as this Coastal Air is too busy--more expense for me and another wait for someone to come.
