One of the county's oldest cities
National City, incorporated in 1887, is the second-oldest city in San Diego County. It sits on San Diego Bay between the City of San Diego and Chula Vista, with the Sweetwater River on its southern edge. Many homes are older, and plenty were built without central air or with small ducts.
Older homes and mixed properties
For older homes, a ductless mini-split or a ducted heat pump is often the cleanest way to add cooling and efficient heat. National City also has plenty of small businesses, and we service commercial HVAC too. We'll look at the electrical service and the layout before recommending anything.
