We're based in San Jose, about 19 miles north, and we book scheduled visits in Day Valley as well as emergency calls at any hour.

What Day Valley Homes Usually Need
Day Valley is on the Santa Cruz County side of the hills from San Jose. For many homes here, heating does more of the work than air conditioning. Cool, damp stretches in winter keep furnaces and heat pumps running steadily. Moisture can also find its way into ductwork, crawl spaces, and indoor air.
Summer cooling needs in Day Valley can look different from the inland and southern parts of the Santa Clara Valley, which run noticeably hotter. That's why we size equipment for your house, how it's built, and how you actually use it. A unit that's too large for a mild-summer home costs more to buy and runs in short, inefficient cycles.

Repairs and 24/7 Emergency Service
When a system stops working, our technician starts by finding the actual cause. A furnace that won't light, a heat pump that blows cool air in heating mode, or an AC that runs but doesn't cool can each have several possible causes. We test before we replace parts, and we tell you what's wrong in plain language.
If your heat goes out overnight or a system fails in a way that can't wait, we offer 24/7 emergency service. Because we travel from San Jose, give us a clear description of the problem when you call. That helps us bring the right parts and diagnose it faster once we arrive.
Replacing a Furnace or Adding a Heat Pump
If your equipment is nearing the end of its life, we'll walk you through repair versus replacement honestly. Many Day Valley homeowners now compare heat pumps with gas furnaces. A heat pump heats and cools with one system, and ductless mini-splits work well in homes without ductwork or for additions and hard-to-heat rooms.
A few things to know before you plan. The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025, so it isn't available for new installations now. Appliance and emissions rules depend on your county and local air district, so a rule you've read about for the Bay Area may not be the one that applies in Santa Cruz County. Local incentives also change by program and funding cycle. We check what applies at your address and confirm any current incentive before we include it in a quote.
Maintenance, Ducts, and Indoor Air
Regular maintenance lets us catch worn parts, dirty coils, and airflow problems before they turn into breakdowns. For heating-heavy homes, a tune-up before the cold season makes sense. Duct cleaning and duct inspection help when you notice dust, uneven temperatures, or musty odors. Our indoor air quality work looks at filtration, ventilation, and humidity so we can recommend changes that fit your home rather than a one-size package.
