United Air Conditioning

United Air Conditioning has kept Largo and Clearwater residents comfortable since 1961, when the founding family opened their doors with a simple promise: treat every customer like a neighbor. Now in its second generation of family ownership, the company has grown into one of the most reviewed HVAC contractors in Pinellas County, holding a 4.9-star rating across 1,336 customer reviews. Their technicians operate around the clock, every day of the year, responding to air conditioning emergencies whether they strike at midnight on a August weekend or during an unexpected winter cold snap.

What distinguishes United Air Conditioning from regional competitors is their breadth of manufacturer relationships and in-house capabilities. As a dealer for major brands including Carrier and Lennox, they install and service traditional split systems alongside advanced variable-refrigerant-flow (VRF) equipment and ductless mini-split heat pumps. Their sheet metal fabrication shop allows them to build custom ductwork rather than outsourcing, while their indoor air quality division offers whole-home humidifiers, dehumidifiers, UV lamps, and air purifiers. The company also handles commercial projects including new construction and full kitchen hood installation.

Reviewers repeatedly single out specific technicians who went beyond standard service calls. When Lisa Kantout's system failed on a Friday, technician Kevin C squeezed her into an already-full schedule, explaining each repair step in terms a non-technical homeowner could understand. During a cold snap in Clearwater, a technician arrived within hours to reprogram Halina Kelemen's eco-friendly heat pump system. DC Carter has relied on United since 2011 across two properties, noting the same-day response time during a recent weekend thermostat failure. These named encounters illustrate a company culture where frontline technicians carry the family business reputation into every home they enter.
