AC Repair & Installation in Fullerton, CA

Fullerton’s Local Dual-Licensed AC & Electrical Contractor

Smartchoice Air Conditioning, Heating & Electrical is one of the few Orange County contractors licensed in both HVAC (CSLB C-20 #1120994) and electrical (CSLB C-10 #1120145), and Fullerton is our home base. When your Fullerton home needs a new air conditioner and the panel upgrade to support it, you call one company instead of two: one crew, one schedule, one warranty. From the historic streets near downtown to Sunny Hills and Amerige Heights, these are the homes we work on every week.

Based in Fullerton, Minutes from Your Home

Our office and warehouse are at 655 S State College Blvd, Unit 29, Fullerton, CA 92831. It’s a working shop, not a showroom, which means our trucks, parts and technicians start the day here. For Fullerton homeowners that means:

• Shorter waits. Most Fullerton addresses are a 5–15 minute drive, so same-day service when you call by noon is the norm, not the exception.
• Parts close by. If a repair needs a part the truck doesn’t carry, it’s usually a quick trip back to the shop, not a next-day order.
• A local track record. Our Fullerton Google profile holds a 4.9-star rating from more than 500 reviews, many from Fullerton neighbors.

Why Fullerton Homes Need Specialists Who Know the Area

Fullerton’s homes span a full century, and each era has its own HVAC and electrical needs:

• Historic homes near downtown. Craftsman, Spanish Revival and early 1900s homes in and around downtown were built without central air, and some still have knob-and-tube circuits and small panels. Adding AC means planning duct routes or ductless heads carefully and checking the electrical first.
• Post-war tracts (1950s–60s). Much of Fullerton was built after the war. Original 60- to 100-amp panels, and brands like Federal Pacific and Zinsco from the 1960s and 70s, are common reasons to upgrade before adding AC, a heat pump or an EV charger.
• Hillside neighborhoods. Sunny Hills, Raymond Hills and the hills along the north side have larger homes with afternoon sun on one elevation. Single-zone systems often leave part of the house hot; zoning or a ductless head fixes it.
• Newer communities. Amerige Heights and other 2000s-era developments have their first or second AC; variable-speed upgrades and repairs, not full redesigns.
• Inland heat. Fullerton summers run well into the 90s, and long afternoon run times wear out capacitors, contactors and fan motors, which is why those are our most common repair calls here.
• Attic ductwork. Ducts that have sat in hot attics for 40 years or more lose insulation and separate at the joints, so cooled air ends up in the attic instead of your rooms.

AC Repair in Fullerton

Call before noon and we can usually have a technician at your Fullerton home the same day. The HVAC service call is $65; it covers the diagnosis and is credited toward the repair, and you get a flat price before any work starts. Our trucks carry the parts that fail most (capacitors, contactors, fan motors and control boards), so most repairs are finished on the first visit. We service every major brand, whoever installed it.

Common Fullerton repair calls:

• An AC that runs but isn’t blowing cold air, usually a capacitor, a contactor or low refrigerant.
• An AC that trips its breaker on hot afternoons, common on older panels. We’re licensed to check the breaker, the wiring and the compressor.
• A refrigerant leak on an R-22 system. You get the repair price and an honest replacement comparison.
• An upstairs or west-facing room that never cools. This is often airflow or duct leakage, not the condenser.

AC Installation & Replacement in Fullerton

A replacement starts with a free in-home assessment. We measure the home, run a load calculation, test the ductwork for leakage (California’s Title 24 HERS test requires it anyway) and look at the panel. Then you get a flat written price.

What we install. Goodman and our AC Pro line, in standard and high-efficiency variable-speed models. For historic homes, additions and ADUs without ducts we install ductless mini-splits, and we also install whole-house fans for homes that cool down well at night.

What it costs.

• AC systems: from $5,950 for 2 tons to about $8,450 for 5 tons, installed.
• AC and furnace together: from $7,500 to about $12,000.

New duct systems, long line-set runs and zoning add to those numbers, and we confirm the final price on site. Every install includes the City of Fullerton permit, the HERS test and inspection, a 10-year parts warranty, a 5-year labor warranty, removal of the old equipment and a year of our maintenance membership.

Repair or replace? We’re a repair-first company. The honest test is the $5,000 rule: multiply the system’s age by the repair estimate. Under $5,000, repair it; over $5,000, replacement usually makes more sense. We show you both numbers.

Financing: 0% interest for 12 months on qualifying HVAC installations, subject to credit approval.

AC Maintenance in Fullerton

A tune-up is $79 per system. For most Fullerton homes the Smartchoice Membership makes more sense: $265 a year (or $22 a month) covers a spring cooling visit and a fall heating visit, 15% off labor on any repair, and priority scheduling in July, when everyone’s system fails at once. Inland heat shortens the life of a dirty coil and a tired capacitor, and most manufacturers require documented annual service to honor the parts warranty.

Heat Pumps & Furnaces for Fullerton Homes

Fullerton winters are mild, which is close to ideal for a heat pump: one system heats and cools efficiently all year. Installed heat pump systems run $6,500–$10,000 for 2.5–3 tons and $9,500–$13,500+ for 4–5 tons. We’re an enrolled contractor with TECH Clean California and confirm current SCE incentives before you commit. Because a heat pump often needs more panel capacity, we size the electrical side on the same visit. If you’d rather keep gas heat, furnace replacements start at $4,500 and run to about $7,250.

Electrician in Fullerton

The dual license matters most when a project crosses trades, and in Fullerton’s older homes it usually does.

• Panel upgrades: 100A to 200A, and 400A. A 200-amp upgrade runs $4,500–$5,000, including the panel, grounding and bonding to code, the permit and the inspection. We coordinate with Southern California Edison and the City of Fullerton, and we replace Federal Pacific and Zinsco panels.
• EV charger installation. A dedicated 240-volt circuit runs $350–$1,250 for labor and materials (charger and permit not included). Tesla Wall Connector and every Level 2 charger.
• Knob-and-tube and older wiring. We evaluate old circuits in downtown-area homes, replace what actually needs replacing, and work carefully around original plaster and trim.
• Breakers and circuits. AFCI/GFCI upgrades, dedicated circuits for AC, kitchens and laundry, and whole-house surge protectors.
• Electrical repairs and rewiring for remodels, additions and ADUs. Electrical repair visits are $149 for the first hour (diagnosis or labor, parts and materials extra), then a flat-rate quote for any remaining work.
