Claim This BusinessAbsolute Comfort Heating & Air Conditioning operates out of Costa Mesa and holds a near-perfect 4.9-star rating across 113 client reviews. The contractor maintains 24-hour availability six days a week, responding to emergency calls whenever Orange County homeowners need relief from extreme heat or sudden heating failures. As a Mitsubishi-certified installer, the team handles both residential ducted systems and light commercial equipment, covering ground-level apartments in the 92626 zip and sprawling homes in Newport Beach alike.
What distinguishes this contractor is an honest repair-first philosophy. Rather than steering every malfunction toward a full replacement, Marc and his crew diagnose whether a component-level fix will restore performance at a fraction of the cost. Several reviewers report receiving repair quotes after other companies insisted on entirely new systems, saving thousands while keeping existing equipment running. The team also carries certifications spanning commercial and residential Mitsubishi lines, a dual credential uncommon among smaller Orange County shops.
Customer stories reveal the human side of these credentials. When Vinh Dang's heater failed two weeks before winter, Marc identified a faulty ignitor and declined to upsell a complete system swap. Courtney Broderick had cycled through multiple Mitsubishi-approved dealers without resolution until Marc diagnosed the issue in a single visit and outlined a concrete remediation plan. Stan Iordanov received the same recommendation from longtime acquaintances who had trusted the company for three decades, citing Marc's straightforward explanations of how the system operates rather than vague promises.
All eight detailed reviewers awarded five stars and praised either Marc or Mark by name, with three specifically noting the team identified problems that other contractors missed. Four reviewers highlighted the repair-versus-replacement guidance as the defining reason for their satisfaction, while two emphasized punctual arrival despite urgent scheduling. No negative reviews were present in the sample set.
