Miami heating, cooling and refrigeration
Cooling repair for Miami homes and businesses, any hour of the day
No-cool calls, full system replacements, duct and air quality work, and the refrigeration that keeps a restaurant open. One number reaches a technician from our south Miami-Dade service office.
Miami service office on SW 117th Ave · We answer 24/7
- Answered 24/7
- Homes and businesses
- Refrigeration too
AC repair in Miami is answered seven days a week by the Frozen Limits HVAC desk: a technician is dispatched from our SW 117th Ave service office for no-cool calls, refrigerant leaks and drain backups, and the same crews replace whole systems, seal attic duct, install mini splits, and keep walk-in coolers and ice machines running for kitchens across Miami-Dade.
Who we serve
Three lines of work, one dispatch desk
Homes, commercial spaces and the refrigeration that keeps a kitchen open all go through the same phone and the same technicians.

Services
Every cooling and refrigeration job we take across Miami-Dade
Grouped the way calls come in. Each link is its own page with the process, what moves the price, and the questions we get on that job.
Emergency & Repair
The calls that come in when something stops: warm air, a tripped breaker, ice on the line, water by the air handler.
Installation & Replacement
New systems sized from a load calculation, permitted with Miami-Dade and anchored to the pad the way the code asks.
Ductwork & Air Quality
The part of the system you never see, and the reason a Miami house can be cool and still feel clammy.
Maintenance & Tune-Ups
Coils, drains, charge and electrical before June, plus the storm-season checks this county needs.
Heat Pumps & Heating
The handful of cold nights a year, and the heat pumps most new Miami systems are built around.
Commercial & Refrigeration
Rooftop units, service agreements, and the walk-ins, reach-ins and ice machines a kitchen can't run without.

Warning signs
Six things that mean call now, not next week
Warm air with the fan running
Usually a capacitor, a tripped condenser or a frozen coil. Shut cooling off and call.
Water on the floor by the air handler
A clogged condensate drain has filled the pan. It will reach the drywall next.
Ice on the copper line outside
Airflow or refrigerant. Running it on ice is how compressors die.
A breaker that trips twice
Something is shorted. Leave it off until a technician meters it.
The house cool but clammy
Short cycling, an oversized system or leaking attic duct. It won't fix itself in August.
A walk-in reading above 41 degrees
Product is at risk from that moment. Kitchens get the same overnight dispatch as homes.
Local conditions
What Miami does to an air conditioner
NOAA normals put the average high at 89 to 91 degrees from June through September, the city logs about 91 days a year at 90 or above, and Miami International Airport hit 100 on August 18, 2026, only the second triple-digit reading in the station's record. A system here runs eight to ten months a year, which is why ten to fifteen years is a normal service life.
Humidity is the second load. Relative humidity sits above 70 percent most of the year, so duct in an unconditioned attic sweats, coils grow mold, and an oversized system that short-cycles leaves a house cool but clammy. The Florida Building Code answers with R-8 attic duct insulation, and Miami-Dade answers with the High-Velocity Hurricane Zone: every outdoor unit is anchored to its pad with hardware named in the permit, engineered for a 175 mph design wind.
Residential work centers on south Miami-Dade around the service office, out through Kendall to Cutler Bay, Palmetto Bay and Homestead and up through Coral Gables and Brickell; commercial and refrigeration accounts run across the county to Doral, Hialeah, Medley and the Beach.

How a job runs
What happens after you call the Miami desk
- 1
You call, a person answers
Any hour, any day. Dispatch takes the symptoms, the address and whether anyone in the house is at risk from the heat.
- 2
A technician leaves the Miami office
Residential calls run out of SW 117th Ave; commercial and refrigeration accounts are covered from both offices.
- 3
Diagnosis before a price
The technician tests the system, shows you what failed, and gives you the repair number and, where it matters, the replacement number beside it.
- 4
Repair or plan the replacement
Most repairs finish on the first visit. Replacements get a load calculation and a scheduled install date.
- 5
Permit, install, inspection
On replacements we pull the Miami-Dade mechanical permit, anchor the condenser to code and schedule the inspection.
- 6
Walk-through before the van leaves
Thermostat settings, filter size and change interval, and the next tune-up date.
No cool, no ice, or a system past its prime? A technician is one call away, any hour.

FAQ
Questions Miami homeowners and managers ask us
Yes. The number on this page is answered around the clock, every day, and overnight no-cool and refrigeration calls are dispatched rather than held for the morning. If every technician is committed we say so, and we may forward the call to another trusted local provider so you are not left waiting.
Residential calls in Miami run out of the service office at 16351 SW 117th Ave in south Miami-Dade. The head office at 6754 NW 72nd Ave in Medley covers the northwest side of the county and most commercial and refrigeration accounts.
Every replacement in Miami-Dade needs a mechanical permit, and we apply with the equipment model and AHRI certificate numbers so the inspection matches what was installed. Swapping equipment without the permit is a code violation, even for a more efficient unit.
Not honestly. The decision depends on the age of the system, the refrigerant it uses, the part that failed and the state of the duct. The technician gives you both numbers on site.
Yes. Walk-in coolers and freezers, reach-ins, display cases, ice machines, PTAC units and ultra-low temperature freezers go through the same dispatch and the same technicians as the HVAC work, so a restaurant makes one call.
Trane, Carrier, Lennox, Rheem, Goodman, Daikin, Mitsubishi Electric, Bryant, York, American Standard and Fujitsu on the HVAC side, and Hoshizaki among the ice machine and refrigeration brands.
