Dalco installed my heating & A/C system several years ago, & I have depended on them ever since for maintenance & minor repairs from time to time. Recently, my A/C pump was leaking water all over the floor. Matt from Dalco came out, & instead of recommending a new pump, cleared the lines with bleach water. It worked perfectly & saved me several hundred dollars! The day is coming when the pump will need to be replaced, but I really appreciate Dalco's efforts to keep things working for as long as possible. Matt has been here a couple of times now, & he has been with the company for over 11 years. This suggests Dalco is a great company to work for; and the customer gets the benefit of professional, experienced technicians. I will always stick with Dalco for my heating & A/C needs.
