Six comprehensive HVAC disciplines, delivered with the precision and pride that has defined Allegiance 76 since 2006.
From residential comfort to industrial-grade climate control, our certified teams tackle every challenge with expert precision.
Expert installation, repair, and maintenance of central AC systems, ductless mini-splits, VRF systems, and rooftop package units. We work with all major brands including Carrier, Trane, Lennox, and Daikin.
From gas furnaces to heat pumps and hot water boilers, we install and service the full spectrum of heating technology. Our technicians are trained on modern high-efficiency systems that cut energy bills dramatically.
We design and install ERV/HRV systems, UV air purifiers, HEPA filtration, and commercial exhaust systems to ensure the air you breathe is clean, fresh, and properly conditioned year-round.
Every new system install includes 2 years of the Patriot Package at no charge. Our Patriot ($209/yr) and Allegiance ($419/yr) plans cover 2–3 visits per year, coil inspections, and more — with diagnostic fees always waived and up to 15% off repairs.
We handle large-scale commercial installs from office buildings and retail centers to warehouses and manufacturing facilities. Our project teams manage design-build, commissioning, and ongoing service contracts.
Upgrade your HVAC with intelligent thermostats, building automation systems (BAS), and remote monitoring. We install and program Nest, Ecobee, Honeywell, and enterprise-grade BACnet/LON systems.
Annual plans designed to keep your system running at peak performance — with exclusive member pricing on every service call.
From single-family homes to multi-million-dollar industrial installations, every project gets our full commitment.
A family-owned California company built on the belief that every home and family deserves honest, high-quality comfort solutions.
At Allegiance 76 Heating And Air Conditioning, we believe comfort isn't just about temperature — it's about taking care of people. We are a family-owned and operated company built on a simple principle: put families first, always.
In an industry increasingly taken over by large private investment groups focused on volume and profit, we chose a different path. We built Allegiance 76 to bring back what matters most — honesty, craftsmanship, and genuine care for the homeowners we serve.
Our company is led by the owner and supported by a dedicated install team who share the same values and standards. Every project is handled with precision, pride, and personal accountability. When you work with us, you're not just another number in a system — you're a family trusting us with your home, and we take that seriously.
We don't believe in high-pressure sales tactics or one-size-fits-all solutions. We focus on educating our customers, providing honest recommendations, and delivering long-term comfort solutions that truly fit your home and your budget.
"Deliver reliable comfort while earning your trust for life."
These aren't slogans on a wall. They're the principles every member of our team lives by on every job, every day.
We do what's right, even when no one is watching.
We treat your home like it's our own.
Every install is done with attention to detail and long-term performance in mind.
When we put our name on a job, we stand behind it.
Hard work, honesty, and commitment to our community.
Allegiance 76 is led by the owner and supported by a dedicated install team who share the same values and hold the same standards on every single job. No subcontractors. No revolving crews. Just people who take pride in their work.
