Fast, reliable air conditioning repair when Miami's heat won't wait.
Your AC runs but doesn’t cool your home, leaving you sweltering in Miami’s tropical humidity despite high energy bills.
Grinding, squealing, or banging sounds indicate serious mechanical issues that need immediate attention.
Your AC turns on and off repeatedly, never reaching set temperature and wearing out components faster.
Pooling water around your unit or frozen coils signal drainage problems that can cause water damage.
Unexplained spikes in electricity costs indicate your AC is working harder than it should.
Miami’s tropical climate puts extraordinary demands on air conditioning systems, with year-round heat, crushing humidity, and salt air accelerating wear. When your AC fails in 95-degree heat with 80% humidity, every minute matters. One Hour Air Conditioning & Heating provides immediate response with certified technicians who understand Miami’s unique cooling challenges. We serve Miami, Miami Beach, Coral Gables, Doral, Homestead, North Miami, Coral Terrace, Cutler Bay, Kendall, Pinecrest, Sweetwater, West Miami, and throughout Miami-Dade County. We arrive within 60 minutes for emergencies, diagnose problems accurately, and restore your comfort fast—guaranteed.
Miami’s intense heat causes specific AC problems we see daily. Refrigerant leaks rob cooling power while corroding coils. Capacitor failures from constant operation leave systems unable to start. Compressor issues from overwork require expert diagnosis. Our NATE-certified technicians carry extensive parts inventory, enabling same-visit repairs for most issues. We use advanced diagnostics including thermal imaging and digital gauges to identify problems precisely, avoiding guesswork and unnecessary replacements that waste your money.
When your AC fails, accurate diagnosis prevents costly misdiagnosis. Our 21-point inspection covers electrical systems, refrigerant levels, airflow, thermostat calibration, and mechanical components. We test capacitors, check amp draws, measure superheat and subcooling, and inspect ductwork. This comprehensive approach identifies not just the immediate problem but underlying issues that could cause future failures. We document findings with photos and measurements, explaining issues clearly so you can make informed repair decisions.
Miami’s climate makes AC failure a health emergency, not just discomfort. Indoor temperatures can exceed 90°F within hours, dangerous for elderly residents and pets. High humidity promotes mold growth in just 24-48 hours without proper cooling and dehumidification. Our rapid response prevents these cascading problems. We maintain multiple service vehicles throughout Miami-Dade County, ensuring technicians reach you quickly with the right parts and tools.
If you’re not completely satisfied with our work, we’ll make it right or refund your money.

While we complete most repairs the same day, some complex issues require specialized parts we may need to order. We’ll provide temporary cooling solutions when possible and expedite parts delivery.
Repair costs vary based on the specific problem, parts needed, and labor required. We provide upfront, written estimates before beginning any work—you’ll know exactly what you’re paying before we start.
