About Unitech Air Co.
Unitech Air Co. operates as an air conditioning repair service in Miami, Florida, maintaining a 4.9 rating across 117 client reviews. The company serves residential and light commercial customers throughout the Miami metropolitan area, handling diagnostics, repairs, system replacements, and preventive maintenance for split systems, packaged units, and ducted configurations. Homeowners in Coral Gables, Kendall, and the surrounding neighborhoods have left feedback describing the team's response to cooling system failures and performance issues.
Reviewers frequently mention same-day service availability, with one customer describing Harold as an AC first responder who arrives the same day during heat waves rather than allowing clients to endure sweltering conditions. Another client noted the technician reapplied mastic sealant to ductwork connections during a maintenance visit, a detail indicating attention to air sealing that affects system efficiency. The company also handles new system purchases and installations, with one reviewer referencing the team's follow-up monitoring of their newly installed central air conditioning unit.
Customers repeatedly call out technician Harold by name, with one 15-year client describing the same technician returning consistently over that period. Another reviewer noted Harold explained each step of the installation process clearly, while a different customer mentioned the technician cleaned both the indoor and outdoor components during a maintenance service call. These scenarios illustrate the company's approach to transparent communication and thorough service delivery.
