Jamison Plumbing and Air

Jamison Plumbing and Air delivers plumbing, heating, and air conditioning services to homeowners across Lake Forest and Foothill Ranch. The company holds a perfect 5-star rating from a single verified review and maintains California contractor license CSLB #1072598, confirming compliance with state bonding and insurance requirements. With two decades of hands-on experience and a documented track record of serving more than ten thousand clients, the team operates around the clock Monday through Saturday to respond to residential and light commercial calls.

What distinguishes this contractor is their transparent flat-rate pricing model, which replaces hourly billing with predetermined job costs to protect homeowners from open-ended invoices. All work performed receives a written guarantee, and the company offers a monthly maintenance program at $12.99 that includes two annual service visits, one for cooling systems and one for heating equipment, to preserve manufacturer warranties and extend equipment lifespan.

Customer reviews highlight specific technicians who arrived same-day during urgent situations. One reviewer praised Brandon for thoroughness and practical recommendations, while another returned customer noted Cory and Brandon prepared their home for winter weather. A third review described Griffin, the project manager, for coordinating a full system replacement with competitive pricing and responsive communication from Ryan.
