Alhambra's Trusted Air Conditioning Repair Provider
Pinnacle Air Experts repairs, installs, and maintains air conditioning and heating systems for homes across Alhambra and the San Gabriel Valley — bringing real technical depth to every diagnosis, not a generic checklist.
About Us
Pinnacle Air Experts is based at 405 S Palm Ave in Alhambra, CA, repairing and installing air conditioning and heating systems for homeowners across the San Gabriel Valley.
Owner Ellis Thornton built the business around technical depth: understanding exactly how a specific system is failing, rather than running through a generic troubleshooting checklist.
What We Do
Real technical expertise applied to your specific system — not a generic troubleshooting checklist.
Technically thorough AC repair that identifies the exact failure — worn capacitors, failed contactors, refrigerant leaks, and blower motor or evaporator coil issues — before any part gets replaced.
Central air and ductless mini-split installation, load-calculated and sized correctly for San Gabriel Valley homes.
Furnace and heat pump repair and installation — igniters, flame sensors, heat exchangers, and full safety inspections — for reliable heat through cooler Alhambra evenings.
Seasonal tune-ups that catch wear before it becomes a breakdown.
In-depth troubleshooting for systems with recurring or unexplained issues.
Filtration and duct-sealing options for cleaner indoor air.

A Homeowner's Guide
Technical depth is hard to see from the outside — but a few questions can reveal whether a technician is actually diagnosing your system or just guessing. Here's what to ask.
A technician who can name the exact part — a capacitor, a leak, a worn contactor — and explain how they found it is diagnosing your system. One who jumps straight to a price usually isn't.
Recharging a system without finding the leak first is a temporary fix that will fail again. A technician who explains how they'll locate it before recharging is doing it right.
California HVAC work should be performed under a licensed contractor, with a firm price in writing before any work starts.
Where We Work
Pinnacle Air Experts serves Alhambra and the surrounding San Gabriel Valley, where Mediterranean summers push highs into the upper 80s through July and August and roughly 280 sunny days a year keep a system working hard for most of it.
