River valley living

Bonsall sits in the San Luis Rey River valley, just east of Oceanside and Camp Pendleton and north of Vista. It is a semi-rural place with horse properties, small ranches and custom homes on larger parcels. The valley floor and the surrounding hills can feel very different on the same afternoon, so we look at exposure, shade and attic conditions before sizing air conditioning.

After the Lilac Fire

The 2017 Lilac Fire burned through parts of the Bonsall area, and some homes were rebuilt or remodeled afterward. Newer homes usually need routine maintenance, while older ones may be ready for a properly sized replacement or a heat pump. Smoke and dust seasons are also a good reason to look at better filtration and indoor air quality.

Questions from Bonsall homeowners

Is Bonsall in your service area?

It is. We serve Bonsall along with the rest of North County San Diego, including the ranch roads off State Route 76.

A ductless mini-split is usually the simplest option for a single room or detached space. We'll check the electrical service and the mounting options first.
