I have used Lucas heat and air for several years and they are the best--honest-reliable--it is owned by Carla and Jerry Coleman and their tech is Gary---I called last week after hours 6pm and my message was returned within 10 min--Carla said I will have Gary out around 7PM--he showed up within 20 min--fixed the problem and air was back cooling. They never pressure-They do my twice yearly check up--they are also reasonable.
