Home Services for Cupertino Homes
Cupertino includes homes from different periods and with very different mechanical, plumbing and electrical setups. Fairgrove alone includes 220 Eichler homes built in the early 1960s, while neighborhoods such as Monta Vista, Rancho Rinconada and Garden Gate have their own mix of original systems and later upgrades.
We inspect the affected system first, then explain what can be repaired, what may need replacement and whether any related plumbing, HVAC or electrical work should be addressed at the same time.
Heating & Air Conditioning in Cupertino
We provide HVAC repair in Cupertino, including AC repair, heating and furnace repair, HVAC maintenance, system replacement and heat pump installation.
If an air conditioner stops cooling, a furnace will not start, airflow drops or the system needs repeated repairs, we diagnose the cause before recommending repair or replacement.
For an urgent cooling problem, see our dedicated Emergency AC Repair in Cupertino service.
Plumbing, Drain & Water Systems
Our Cupertino plumbing services include leak detection, pipe repair, drain cleaning, sewer service, water heater repair and replacement, fixture installation and whole-home repiping.
Older piping, recurring leaks, low water pressure and repeated drain problems can point to an issue beyond a single fixture. We trace the source before recommending a repair, partial replacement or larger repiping project.
Electrical Services & EV Charging
We provide electrical troubleshooting, electrical panel inspection and replacement, rewiring and EV charger installation in Cupertino.
Older electrical systems may need to be evaluated before adding equipment such as a heat pump, heat-pump water heater or Level 2 EV charger. We can check the existing panel and circuit capacity as part of planning the upgrade.
Permits and Home Electrification in Cupertino
Many HVAC, plumbing and electrical projects in Cupertino require permits. The City offers an Instant Permit process for qualifying projects such as same-location furnace replacements, interior whole-house repiping, electrical panel upgrades, certain standard gas water heater replacements and Level 1 or Level 2 EV charger installations.
Projects that do not meet the Instant Permit requirements follow the standard permit process. Cupertino also provides separate guidance for heat-pump HVAC and heat-pump water heater upgrades.
Cupertino residents may qualify for current electrification rebates through Silicon Valley Clean Energy, including eligible heat-pump HVAC systems, heat-pump water heaters and related electrical work. Program requirements and rebate amounts can change, so eligibility should be checked before equipment is purchased.
