Wholly woman-owned Paradigm has achieved exponential growth since its foundation in early 2010 – while maintaining an unwavering commitment to our clients’ unique project and safety needs.

Today, we leverage our extensive project team experience, technical knowledge, and creativity to address and implement solutions to any challenge – presented by any building project – all across Southern California.

Paradigm Team 2017.png

From a startup group of four with two commercial vehicles to a talented team of 40-plus employees and a thriving construction fleet of 18, we're moving confidently in the right direction.

As an energetic and solution-oriented company, we find a way to always get the job done. Not every HVAC company has the experience, knowledge, and wherewithal to take on projects that require special inspections or after-hours critical shut-downs. Paradigm does. And this is part of what sets us apart from our competition.

Our difference is also defined by our customized attention to our clients’ individual needs. Our process begins by sitting down together to discuss all your mechanical needs. We then present a comprehensive evaluation and options menu – including engineering concepts, budgetary information, and scheduling. If needed, we offer general contracting services to encompass all trades, providing a full turnkey project. We also make sure to never commit to a particular brand of HVAC equipment – providing us with flexibility and a competitive edge in acquiring the right product, at the right price.

Ideally situated near multiple San Diego freeways in Lemon Grove, CA, the Paradigm field and service teams can be deployed on the road to several job sites in mere minutes.
