HVAC Company in Hillsborough, CA
Hillsborough’s exclusively single-family estate homes, many built between the 1920s and 1950s with radiant heating and no original cooling, create HVAC challenges that differ sharply from standard suburban jobs. We handle everything from steam boiler repairs in Tudor Revival homes to multi-zone AC installations in newer custom builds, with pricing that starts with a written estimate before any work begins. Most repair calls in Hillsborough are answered by a live person and scheduled with a firm arrival window. Call (817) 402-2972 to speak with our dispatch team.
Why Hillsborough Homes Are Different
Hillsborough’s municipal code bans apartments and commercial buildings entirely, so every HVAC job we take here involves a large custom estate, not a tract home or condo. Many of these houses were built in the 1920s through 1950s in Mediterranean Revival, Tudor, and Colonial Revival styles with plaster-over-lath walls, high ceilings, and original steam or hot-water radiant heating systems. That construction makes traditional ductwork retrofits invasive and costly, which is why we often recommend ductless mini-splits or hydronic cooling solutions instead.
The city’s architectural review process adds another layer. All mechanical equipment, condensers, air handlers, and exhaust vents must be screened from street and neighbor view before permits issue. We’ve seen condenser replacements that should take a day stretch to three weeks because an out-of-area contractor didn’t submit equipment-screening plans upfront. Hillsborough also sits on the mid-peninsula hillside, giving it a microclimate warmer and less fog-bound than coastal San Mateo County, yet mild enough that central air was rarely installed until recent Diablo-wind heat events pushed temperatures into the low-to-mid 90s and exposed how poorly thick plaster walls and single-pane steel casement windows retain comfort.
Our Main Hillsborough Services
Most calls we get from Hillsborough fall into three categories: cooling repairs during heat events, heating repairs when radiant systems fail, and new AC installations for homes that never had central air. Each has its own page with Hillsborough-specific details.
AC Repair in Hillsborough
When Diablo winds push Peninsula temperatures into the 90s, Hillsborough homes with thick plaster walls and steel casement windows heat up fast and cool down slowly. We repair all major brands, including Rheem and York systems, and carry common capacitors, contactors, and refrigerant on our trucks to avoid delays. Because many Hillsborough AC systems were retrofitted into homes without original ductwork, we often find issues at the indoor coil or refrigerant lines rather than the outdoor condenser alone.

Furnace Repair in Hillsborough
A large share of Hillsborough heating is still steam or hot-water radiant, not forced air, so “furnace repair” here often means boiler work, circulator pumps, or zone valve replacement. We also service conventional gas furnaces in newer custom builds from the 1980s onward. Our technicians are trained on both hydronic and forced-air systems, and we stock common boiler parts because a failed circulator on a January night in Hillsborough is not a next-week problem.

AC Installation in Hillsborough
New cooling systems in Hillsborough must clear architectural review before permits are issued, which means equipment-screening plans showing hidden condensers behind custom enclosures or dense landscaping. We coordinate this step from the start so it doesn’t surprise the timeline or budget. For older estates without ductwork, we often design ductless mini-split or hydronic cooling systems that avoid tearing open plaster walls. Every installation gets a written fixed price and a scheduled start date. AC Installation in Hillsborough

What Hillsborough Customers Say
"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito
