Jamison Heating & Cooling Services, Inc.

Fullerton has been home to Jamison Heating and Cooling Services since 2016, earning a 4.9-star average across 360 verified reviews. As a licensed HVAC contractor serving Fullerton, Placentia, and La Mirada alongside all of Orange County, the team handles everything from residential air conditioning tune-ups to light commercial projects. Their weekday availability stretches from 8 AM to 8 PM, making it easier for working households to book routine service without disrupting their schedules.

What distinguishes this contractor is their commitment to straightforward transactions, a trait that surfaces repeatedly in customer feedback. Reviewers consistently use the word "honest" when describing interactions, noting that technicians present options without pressuring homeowners toward expensive upgrades. The crew completed a same-day heat pump installation for one Fullerton household using a coordinated three-person team, finishing the job cleanly and walking the homeowners through the new system's operation before leaving the property tidy.

Cesar earned particular praise across multiple reviews for his thorough explanations and respectful approach, handling both routine maintenance visits and diagnostic assessments without recommending unnecessary work. Another technician, Isidro, responded to a heating emergency for a freezing household on the same day the call came in, diagnosing the fault and ordering the required replacement part within hours. Steven Jareb's neighbor originally recommended Jamison after receiving a competitive quote for a heat pump replacement, and the subsequent installation involved Oscar, Tony, and Armando completing the full setup in a single day.
