Cassel Air Conditioning & Heating Service

Founded in 1989, Cassel Air Conditioning & Heating Service has spent more than three decades building a reputation as Fair Oaks' go-to HVAC specialist. The family-owned operation, now in its second generation with experience tracing back to 1982, holds California State License #825314 and has earned a perfect 5.0-star rating across 93 reviews. Serving Fair Oaks, Orangevale, Folsom, and the broader Sacramento County area, the team travels up to 30 miles to bring heating and cooling solutions to homeowners who need them most.

What distinguishes Cassel from otherarea contractors is their commitment to honest, straightforward service in an industry often criticized for upselling. The company works with most major brands, including Trane systems, and handles everything from traditional furnaces and heat pumps to modern Wi-Fi thermostats. Their BBB accreditation provides an extra layer of accountability, while their preventive maintenance approach helps homeowners avoid costly emergency repairs down the line. Unlike contractors who push unnecessary upgrades, Don and his team recommend repairs when appropriate and installations only when truly needed.

Customer reviews paint a consistent picture: Don Cassel responds quickly, explains problems clearly, and delivers quality work without gimmicks. When one Fair Oaks homeowner's 20-year-old HVAC unit finally failed, Don provided a competitive quote, installed a new Trane system along with whole-house and attic fans in just three days. Another reviewer called about furnace issues at 6 PM and Don arrived the next morning, diagnosing the problem in minutes and refusing payment because the fix took only 15 minutes. This level of personal attention, backed by nearly 40 years of family experience, keeps customers calling Don first for every heating and cooling need.
