Canoga Park's Trusted Air Conditioning Repair Provider
Highmark Air Conditioning repairs, installs, and maintains air conditioning and heating systems for homes across Canoga Park and the West Valley — starting every call with an honest look at whether a repair will do the job.
About Us
Highmark Air Conditioning is based at 7118 Jordan Ave in Canoga Park, CA, repairing and installing air conditioning and heating systems for homeowners across the West San Fernando Valley.
Owner Trevor Boone built the business around a repair-first philosophy: a system that can be fixed properly should be fixed, not replaced just because it's easier to sell a new one.
What We Do
Real repair work first, honest replacement advice when a system has truly reached the end of the line.
Thorough diagnostic repair aimed at fixing the actual problem — refrigerant leaks, failing capacitors, worn contactors, and blower motor or airflow issues — without defaulting to a system replacement.
Central air and ductless mini-split installation, load-calculated and sized correctly for West Valley homes, recommended only when repair genuinely isn't the better option.
Furnace and heat pump repair and installation — igniters, flame sensors, heat exchangers, and full safety inspections — for reliable heat through cooler Valley evenings.
A fresh, honest look at a system another company recommended replacing.
Seasonal tune-ups that extend a system's working life.
Airflow and insulation checks for rooms that never quite cool down.

A Homeowner's Guide
A repair-first approach only means something if the technician is honest about when a repair really is the answer. Here's what to check before you hire anyone.
A technician should be able to name the actual failed part — a capacitor, a leak, a worn contactor — before recommending replacement. If "you need a new system" is the first thing you hear, ask why.
Even when replacement turns out to be the right call, a contractor who prices the repair too — and explains why it isn't the better long-term value — is being straight with you.
California HVAC work should be performed under a licensed contractor. Get a firm, written price before work starts, not a number that changes once the job is underway.
Where We Work
Highmark Air Conditioning serves Canoga Park and the surrounding West San Fernando Valley, where the valley heat trap pushes summer highs into the high 80s and mid-90s through July and August — the kind of stretch that exposes any part already on its way out.
