Claim This BusinessAbout Mason's Air Conditioning & Heat
Mason's Air Conditioning & Heat has kept Nassau County comfortable for over 20 years. Based at 1438 East Oak St. in Fernandina Beach, the company holds Florida license CAC 058303 and carries a 4.3-star rating across 42 reviews. The firm serves residential and light commercial customers throughout Fernandina Beach and the surrounding Amelia Island corridor, emphasizing the kind of care they would provide their own household.
What distinguishes this contractor is their insistence on thoroughness over speed. Their website touts full inspections, coil cleaning, and honest assessments rather than brief visits that merely charge for an hour without solving the underlying problem. The 24-hour emergency line means someone answers anytime, and the Best of the Best honor from The Newsleader confirms their standing locally.
Customer reviews name specific technicians who delivered exceptional service. When Tammi Bach called on a Saturday morning, a technician arrived by 8:00 AM and had her A/C working by 12:30 PM. When she called back questioning the cool-down time, the owner himself took her call, and within two hours a tech returned voluntarily to verify everything was perfect. Another reviewer references Casey's responsive follow-up as the reason the business retained a loyal customer.
What Customers Say
Among four detailed reviews, two award 5 stars citing rapid response and personal follow-through, while one 2-star review faults rushed visits that skipped full inspections, and a 4-star review notes higher pricing despite acceptable workmanship. Positive sentiment centers on the owner-level involvement; negative sentiment targets incomplete diagnostics.
