If your air conditioner is past its prime or you’re tired of patching a system that quits every August, AC Installation - Miami isn’t a luxury project, it’s what keeps your house livable from May through October. A new system sized right for your home’s square footage and Miami’s humidity load will cool more evenly, pull less power, and stop surprising you with repair bills. Cold Harbour Heating and Air Miami has installed air conditioning across Miami since 2003, and every job starts the same way: a written price handed to you before any equipment is ordered, a firm arrival window, and a 365-Day Done Right Promise on the work. Call (850) 810-1910 and a live person will answer, day or night.
Furnace Installation
Furnace Installation means replacing or adding a heating system that warms your home by burning fuel or running electric elements and pushing that heat through your ductwork. Miami homes need furnaces far less than northern houses, but the occasional cold front in January and February makes a working furnace worth having, and plenty of older Miami houses still run original units from the 1980s and 1990s that are overdue for replacement. Cold Harbour Heating and Air Miami installs furnaces sized to your actual ductwork, not a guess from a square-footage chart, and every installation carries a written price before work starts plus the 365-Day Done Right Promise. Furnace installation in the Miami area typically runs $4,130 to $8,850 depending on furnace efficiency, fuel type, and whether the ductwork needs modification. Our technicians are trained on Trane, Lennox, Carrier, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment.
Sizing for Miami’s Short Heating Season
Oversized furnaces short-cycle in Miami’s mild winters, which wastes fuel and causes temperature swings. We match the furnace’s output to your home’s actual heat loss, not a national average.
Ductwork Coordination
Many Miami furnace replacements need duct transitions or minor modifications to align the new unit with existing plenums. We inspect and quote that work up front so the written price doesn’t change on install day.
Styles & brands we work with
HVAC Installation
HVAC Installation covers the full heating and cooling system: the outdoor condenser, the indoor air handler or furnace, the evaporator coil, the thermostat, and the connections that make them work together. When a Miami homeowner replaces both halves of the system at once, they get matched efficiency ratings and a warranty that isn’t voided by mismatched components. Cold Harbour Heating and Air Miami installs complete HVAC systems with a written price before any work begins and a 365-Day Done Right Promise on every install. Full HVAC installation in Miami generally falls between $4,130 and $8,850, with the spread driven by equipment efficiency (SEER2 rating), brand, and whether new refrigerant lines or electrical upgrades are required. We walk you through the quote line by line so you know exactly what each number covers.
Matched Systems, Real Efficiency
Pairing a high-efficiency condenser with an old indoor coil kills the efficiency rating and can shorten compressor life. We spec both halves together so the system performs the way the manufacturer rates it.
Thermostat and Controls
Every HVAC installation includes a properly configured thermostat and system controls. We set up scheduling and humidity control for Miami’s coastal climate, then show you how to use them before we leave.
Heat Pump Installation
Heat Pump Installation is the process of putting in a system that both cools and heats your home by moving heat from one place to another instead of burning fuel. For Miami homes, a heat pump handles air conditioning in summer and provides efficient heating on the rare cold nights without the gas line or combustion venting a furnace needs. Cold Harbour Heating and Air Miami installs heat pumps sized for Miami’s heat and humidity, with a written price in your hand before the work begins and the 365-Day Done Right Promise on the finished job. Heat pump installation in Miami typically costs $4,130 to $8,850 depending on the system’s SEER2 rating, capacity, and whether backup heat strips are included. We carry training and parts support for major brands including Bryant, Daikin, and York.
Humidity Control in Cooling Mode
Miami’s humidity makes the air feel hotter than the thermometer says, so we pay close attention to airflow settings and coil sizing. A heat pump tuned for dehumidification keeps your home comfortable at a higher thermostat setting, which cuts your electric bill.
When Backup Heat Makes Sense
Heat pumps lose capacity as outdoor temperatures drop, so some Miami homeowners add electric heat strips for those 40-degree January mornings. We quote that option separately and explain exactly when it would actually run.
Ductless Mini Split Installation
Ductless Mini Split Installation puts an outdoor condenser together with one or more wall-mounted indoor units connected by a small refrigerant line, no ductwork required. Miami homeowners choose mini splits for garages, sunrooms, additions, older homes without ducts, or rooms that never quite cool enough with the central system. Cold Harbour Heating and Air Miami installs ductless systems with a written price before work starts and the 365-Day Done Right Promise on the completed installation. Ductless mini split installation in Miami usually runs $4,130 to $8,850 depending on the number of indoor heads, the system’s capacity in BTUs, and the length of the line set run. Our technicians are trained on Daikin, Mitsubishi-style systems, and American Standard ductless equipment.
Multi-Zone Comfort Without Ducts
One outdoor unit can serve multiple indoor heads, letting you cool a master bedroom and a home office at different temperatures. We design the layout around your actual room usage, not a generic floor plan.
Older Homes, Modern Cooling
Homes built before central air was standard often have no practical way to add ductwork. Mini splits solve that without tearing out ceilings or walls, and the installation is typically finished in a single day per indoor unit.
AC Replacement
AC Replacement is a new outdoor condenser and indoor coil installed to take over for a system that’s at the end of its useful life. If your current unit is over 12 years old, needs refrigerant the manufacturer no longer produces, or has had two major repairs in the last three years, replacement usually beats repair on total cost. Cold Harbour Heating and Air Miami replaces AC systems with a written price delivered before any equipment is ordered, and the entire replacement is covered by the 365-Day Done Right Promise. AC replacement in Miami typically costs $4,130 to $8,850 depending on SEER2 rating, system capacity, and the condition of your existing ductwork and electrical service. We handle the full job including disposal of the old equipment and startup testing.
Refrigerant Phaseout Considerations
Older systems running R-22 refrigerant are getting harder and more expensive to service as supply dries up. Replacing now gets you onto current refrigerant and future-proofs your parts availability for the next decade-plus.
What We Check Before Quoting
We look at your ductwork condition, electrical panel capacity, pad placement, clearance, and line set length before writing a number. That’s why our written quote doesn’t change when the crew arrives.
Central Air Conditioning Installation
Central Air Conditioning Installation means putting in a complete split system: an outdoor condenser, an indoor evaporator coil, and the refrigerant lines that connect them, all working with your home’s ductwork. For most Miami houses, central AC is the most cost-effective way to cool every room evenly from a single thermostat. Cold Harbour Heating and Air Miami installs central air systems with a written price in your hand before work starts, a firm arrival window, and the 365-Day Done Right Promise on the completed installation. Central air conditioning installation in Miami commonly runs $4,130 to $8,850 depending on the system’s capacity in tons, its SEER2 efficiency rating, and any duct or electrical work required. We train our techs on nine major brands including American Standard, Bryant, and York.
Load Calculation, Not Guesswork
We calculate the cooling load based on your home’s square footage, window orientation, insulation, and Miami’s design temperature. A system sized by rule of thumb costs more to run and never dehumidifies properly.
Startup and Airflow Verification
After installation we measure supply and return temperatures, check static pressure, and set fan speeds for humidity control. You get a written record of the system’s startup performance before we leave.
Brands We Service
Our technicians are factory-trained and field-experienced with York, Daikin, and Bryant equipment, among others. On York systems we’re familiar with the Affinity and LX series condensing units, including their coil pairing requirements and common control board configurations. For Daikin, we work with both their traditional split systems and the ductless line, and we stock common Daikin-specific parts like inverter boards and thermistors. With Bryant units, we handle the Evolution and Legacy lines and know the warranty registration process that keeps your parts coverage intact.
We also service American Standard equipment, so if you have an existing American Standard system and want to stay with the brand, we can quote the replacement and handle the install. Whether you have one of these brands or any other make, our techs can work on what’s already in your home and give you a straight answer on repair versus replacement.

- Warm air blowing from your vents – If your AC runs but the air coming out isn’t cold, the compressor may be failing, the refrigerant charge may be low, or the reversing valve could be stuck. This won’t fix itself, and continuing to run the system can cause further damage.
- The system short-cycles – An AC that turns on and off every few minutes is either oversized, low on refrigerant, or fighting a failing thermostat. Short cycling wears out compressors and drives up your electric bill in a hurry.
- Water pooling around the indoor unit – A clogged condensate drain or a frozen coil that’s thawing can dump water on your floor and into your drywall. In Miami’s humidity this happens fast, and mold follows within days.
- Humidity that won’t drop – If your home feels sticky even when the temperature reads 72, your system isn’t removing moisture the way it should. That’s often a sign of an oversized system or a failing compressor, both of which a technician should evaluate.
- Electrical smells or burning odors – A burning smell from your vents can indicate a failing blower motor, a bad capacitor, or wiring that’s overheating. If you notice this, shut the system off and call right away.
Our Process, Step by Step
- 1
Call and talk to a live person – When you call (850) 810-1910, a real human answers, not a phone tree. We take your information, ask about the symptoms or the project you have in mind, and schedule a visit during a window that works for you.

You get the 365-Day Done Right Promise in writing – Before we leave, you receive a written guarantee on the installation. If anything isn’t done right within 365 days, we come back and correct it at no charge. No arguments, no fine print.
How Much Does AC Installation Cost in Miami?
A typical AC Installation pricing in Miami runs $4,130 to $8,850. The spread comes down to a handful of factors: the system’s cooling capacity in tons, its SEER2 efficiency rating, whether you’re replacing just the outdoor unit or the entire system including the indoor coil, and the condition of your existing ductwork and electrical panel. A basic 2-ton single-stage system for a small condo or townhome in areas like Kendale Lakes or Coral Terrace will land near the lower end. A variable-speed, high-SEER2 system for a larger single-family home in Aventura or The Crossings with duct modifications and electrical work will push toward the top.
What affects the price most is equipment efficiency and capacity. Higher SEER2 ratings cost more up front but cut monthly electric bills, which matters in Miami where air conditioning runs nearly year round. Ductwork condition matters too: if your ducts are leaking, undersized, or need transitions to fit the new equipment, that work gets quoted separately and clearly. The best way to avoid overpaying is to get a written, line-item quote and compare what’s actually included: equipment, labor, refrigerant, electrical, permits, disposal, and startup. Our free estimate includes all of it, and the number we hand you is the number you pay. Call (850) 810-1910 to schedule yours.
