Our highly skilled technicians ensuring your equipment operates efficiently and safely.
Smartchoice Service Inc. has been working in Mission Viejo since 2017 — from the original 1960s tracts near Marguerite Parkway to the 1980s hillside neighborhoods above Lake Mission Viejo and the newer infill homes around the Shops at Mission Viejo. We’re a family-owned, dual-trade contractor licensed in both HVAC (CSLB C-20) and electrical (CSLB C-10) under #1120994. In a community where most original systems have been replaced once and need replacing again, we’re often the third or fourth contractor a homeowner has worked with on the same house — and the first to actually look at the system holistically.
Mission Viejo’s original homes were built before the 1979 California Title 24 energy code. That means most have undersized return air, leaky attic ducts, and air handlers in 90+ degree summer attic spaces. Just replacing the condenser doesn’t fix the underlying problem. We diagnose the whole system: duct integrity, return-air sizing, refrigerant line condition, and whether the existing tonnage is even right for the home’s current envelope. A properly designed HVAC retrofit in a 1970s Mission Viejo home routinely cuts cooling bills 30-40% over a like-for-like replacement.
For the lakeside neighborhoods (Lake Mission Viejo has restricted access, but the homes with views on Aegean Hills, Pacific Hills, and Castille face their own microclimate from the water), we account for the higher humidity loads with two-stage or variable-capacity systems that can run longer at lower output — dehumidifying as they cool rather than short-cycling on/off.
For Mission Viejo’s HOA-heavy neighborhoods, we know which equipment will pass architectural review and which won’t. We handle the HOA paperwork side of installs so you don’t get a violation letter after the work is done.
The electrical issues in 1960s-70s Mission Viejo homes are predictable: 100-amp service panels that need upgrading to 200 amp, aluminum branch wiring at outlets that needs proper terminations or replacement, GFCI protection missing in kitchens and bathrooms, AFCI protection missing in bedrooms (required for any rewire), and undersized neutral conductors on the original service feed. These are common, fixable issues — we handle them every week.
For the newer infill construction in Mission Viejo (the 2000s+ homes near the Oso Creek Trail and the Shops at Mission Viejo), we focus on EV charger installs, smart-home circuit additions, and panel reorganization to make room for solar/battery integrations.
When you upgrade a Mission Viejo home from a 1975 HVAC system to a modern heat pump, you’re almost always also dealing with the home’s original 100-amp panel. Adding a 240V/50A circuit for the heat pump can max out an old panel — which means the heat pump install can’t be approved until the panel is upgraded. Coordinating both trades under one license eliminates two service calls, two diagnostics, and the awkward week-long gap between when one contractor finishes and the other starts.
We respond to service calls throughout Mission Viejo: Aegean Hills, Andalusia, Aliso Hills, Casta del Sol, Castille, Deane Homes, Madrid del Lago, New Madrid, Pacific Hills, Pacific Ridge, Palmia, Quail Hills, The Greens, and the lakefront-adjacent homes. Whether you’re in an original 1965 Marguerite Parkway tract home or a 2000s build near the Shops at Mission Viejo, we’ve worked on systems like yours.
