How It Works
From the call to the final walkthrough
- Step 1
Call & Dispatch
Call at any hour and describe the problem — no cooling, no heat, weak airflow or an unusual sound or smell. Dispatch confirms your address in Miami-Dade and sends a technician.
- Step 2
System Diagnosis
The technician tests the system: thermostat and electrical components, refrigerant pressures, coils, blower and airflow, to identify the fault.
- Step 3
Written Assessment
Before work starts, you receive a written assessment of the fault and the repair or installation proposed, so the scope is clear in advance.
- Step 4
Repair or Installation
The agreed work is carried out — a component repaired or replaced, or new equipment installed and connected.
- Step 5
Testing & Airflow Check
The system is run through a full cycle. Temperatures and airflow are checked at the vents to confirm it is heating or cooling as it should.
- Step 6
Walkthrough
The work is reviewed with the homeowner, including what was found, what was done, and the maintenance steps that keep the system running.
Why This Service
One dispatch for repair, installation and upkeep
When the air conditioning stops on a hot night, there is little time to call around separate companies for diagnosis, repair and follow-up maintenance. Air Heat Dispatch coordinates the sequence through one dispatch number, around the clock, across Miami-Dade County.
Each visit is documented: the fault found, the readings taken, and the work performed. That record belongs to the homeowner — it supports future maintenance decisions and any warranty paperwork for installed equipment.
Technicians across Miami-Dade
Dispatch coordinates technicians positioned around the county, so service starts from within the area rather than across the state.
Diagnosis before decisions
Refrigerant pressures, coils, electrical components and airflow are tested and recorded before a repair or replacement is proposed.
Cooling and heating in one service
The same dispatch covers AC repair, heating repair and heat pumps, so the system is looked after in both seasons.
One team from diagnosis to testing
The same dispatch coordinates diagnosis, the agreed work, and the final temperature and airflow checks, so nothing is handed off between separate companies.
Scope agreed before work starts
The assessment is written out and agreed with the homeowner before the work begins, so what will be done is clear in advance.

Answers before you call
Straight answers to the questions Miami homeowners ask most — and dispatch can help with anything else, 24/7.
What should I check before calling for AC repair?
Check the thermostat first: it should be set to cool, and the set temperature should be below the room temperature. Then check the breaker panel for a tripped breaker serving the air handler or the outdoor unit, and look at the air filter — a clogged filter restricts airflow and can cause weak cooling or a frozen coil. If the system still does not cool after those checks, call dispatch so a technician can diagnose the fault.
How much does AC repair cost in Miami?
The main factors are the type of fault, the parts involved, and the age and size of the system. A failed capacitor or contactor is a smaller repair than a compressor or a refrigerant leak that has to be located and sealed. After diagnosis, you receive a written assessment of the fault and the repair before work starts, so the scope is clear in advance.
How often should HVAC be serviced in Florida?
Typically twice a year. Cooling runs most of the year in South Florida, so systems accumulate operating hours faster than in cooler climates, and a visit before the summer peak and another during the year keeps coils, drainage and electrical components in check. Between visits, check the air filter monthly and replace it every 1 to 3 months.
How long does a central AC last in South Florida?
Commonly 10 to 15 years with regular maintenance. Heat, humidity and coastal salt air shorten service life, and a system that runs year-round accumulates wear faster. Frequent repairs, uneven cooling and long run times are common signs that a system is approaching replacement age.
What size AC does my home need?
The right size comes from a load calculation, not a rule of thumb. Square footage is only one input — insulation, window area and direction, ceiling height and the number of occupants all change how much cooling a home needs. During an installation assessment, a technician measures these factors so the selected system matches the home.
What should I do while waiting for the technician?
Leave the thermostat as it is unless there is ice on the indoor unit or the refrigerant lines — in that case, switch the system to fan-only or off so the ice can melt before the visit. Keep the area around the indoor and outdoor units clear, and note any sounds, smells or error codes the system showed, as those details help with diagnosis.
