Comprehensive Air Conditioning Service Solutions

When your air conditioning system needs attention, whether for routine maintenance or emergency repairs, we understand how crucial reliable service becomes. Our approach to air conditioning service combines technical expertise with a commitment to customer satisfaction that has defined Mills Air since 1992. We’ve built our reputation on responding quickly to service calls and diagnosing problems accurately the first time. Our technicians undergo continuous training on the latest equipment and diagnostic techniques, ensuring we can service virtually any make or model of air conditioning system currently in use across residential and commercial properties.

The subtropical climate of Central Florida demands air conditioning systems that operate efficiently year-round. We’ve developed service protocols specifically tailored to address the unique challenges our local environment presents, from high humidity levels that can strain condensate drainage systems to the constant thermal cycling that components experience during our extended cooling season. Our service vehicles carry extensive inventories of commonly needed parts, allowing us to complete most repairs during the initial service visit rather than requiring multiple appointments.

Preventative AC Maintenance Programs

Regular maintenance represents one of the most cost-effective investments you can make in your air conditioning system. Our comprehensive maintenance programs include detailed inspections of all system components, from checking refrigerant levels and testing electrical connections to cleaning coils and calibrating thermostats. We examine your system’s performance metrics against manufacturer specifications, identifying potential issues before they develop into costly breakdowns. During each maintenance visit, our technicians clean or replace air filters, inspect ductwork connections, verify proper airflow across evaporator coils, and test safety controls to ensure your system operates safely and efficiently.

Leon Mills, our Founder & CEO, established these thorough maintenance protocols from day one, understanding that preventing problems costs far less than fixing them after failure occurs. Leon’s goal from day one has been to provide the best quality service and equipment to the valued customers, while building an internal culture of team and family. This philosophy drives our maintenance approach, where we treat each system as if it were installed in our own homes. Our maintenance agreements provide priority scheduling for service calls, discounted rates on repairs, and extended warranties on parts, delivering peace of mind alongside improved system performance.

Emergency Air Conditioner Repair Services When You Need It Most

Air conditioning failures rarely occur at convenient times, which explains why we maintain emergency AC service availability throughout Orlando, College Park, Winter Park, Altamonte Springs, Casselberry, Longwood & Winter Springs, FL. Our staff consists of over 75 people and with a fleet of trucks ready to service all your needs, ensuring rapid response when your system stops working. We’ve structured our service department to handle multiple emergency calls simultaneously without compromising service quality or response times. Our dispatchers coordinate technician schedules efficiently, routing service calls based on geographic proximity and urgency levels to minimize customer wait times.

When responding to emergency calls, our technicians perform systematic diagnostics to identify root causes rather than simply addressing symptoms. Common emergency repairs include:

Compressor failures: Complete testing of electrical components, capacitors, and refrigerant pressures to determine whether repair or replacement provides the best value
Refrigerant leaks: Electronic leak detection, system evacuation, repair of leak sources, and proper refrigerant charging according to manufacturer specifications
Electrical malfunctions: Comprehensive testing of contactors, relays, circuit boards, and wiring connections to restore proper system operation

In addition to routine preventative maintenance checks, service of existing air conditioning equipment, and installation of new air conditioning equipment, we also offer energy surveys that can uncover ways for you to reduce costly utility bills. These comprehensive evaluations examine your entire system’s efficiency, including ductwork integrity, insulation effectiveness, thermostat programming, and equipment sizing relative to your space’s cooling load. Our energy specialists use advanced diagnostic tools including thermal imaging cameras and airflow meters to identify efficiency losses that might not be apparent during routine service calls. Based on our findings, we provide detailed recommendations ranging from simple adjustments to equipment upgrades, always focusing on solutions that deliver meaningful returns on investment through reduced operating costs.
