Mini Split Installation

Mini Split Installation puts a heat pump where ductwork can’t reach, and in Miami that matters more than people realize. A mini split is a heat pump system with an outdoor compressor unit and one or more indoor air handlers mounted on the wall, ceiling, or floor, with a small conduit carrying refrigerant and power between them. You need it when you have a converted garage, a sunroom, a finished attic, or any room that never holds temperature because your central system can’t force air through the space. We install single-zone and multi-zone mini splits, and a typical installation in Miami runs $4,130 to $8,850 depending on the number of indoor heads and whether the electrical panel needs work. The unit itself, whether it’s a Daikin, Bryant, or York, should be matched to the square footage and the south-facing glass that drives heat load in Miami afternoons.

Single-Zone vs. Multi-Zone Systems

Single-zone means one indoor head and one outdoor unit. That’s the right call for a single room like a home office or a mother-in-law suite. Multi-zone puts two to five indoor heads on one outdoor condenser, which is cheaper than installing separate outdoor units for each room and takes less space on the side of the house.

Electrical and Placement Considerations

Older Miami homes, especially in Westchester and West Little River, often need a dedicated circuit run to the outdoor unit before we can mount the indoor head. That cost is included when we hand you the written price, not added after we open the wall. Placement matters: an air handler mounted on an interior wall near the ceiling gives better throw across the room than one tucked behind a door swing.

Heat Pump Maintenance

Heat Pump Maintenance is the difference between a system that runs eleven years and one that runs sixteen, and in Miami’s salt air and humidity, it’s not optional. Because a heat pump runs year-round, doing both the cooling in summer and the heating in winter, it collects more runtime hours than a furnace and AC combo, so the coils, the condensate line, and the reversing valve all need a professional look at least twice a year. We perform this maintenance for $95 to $235 per visit depending on system size and condition, and every visit includes a written report of what we measured, what we cleaned, and what we saw wearing down before it fails. The report matters, because it puts the condition of your system in writing so you can plan a replacement on your schedule, not on the schedule of a compressor that dies in July.

Coil Cleaning and Airflow Checks

Miami’s airborne salt and pollen coat the outdoor coil faster than people think. A dirty coil pushes head pressure up, and high head pressure shortens compressor life. We measure static pressure and temperature split on every maintenance call so we are working from numbers, not guesses.

Reversing Valve and Defrost Verification

The reversing valve is the part that flips the system from cooling to heating, and it’s the single most common failure point on a heat pump. During maintenance we cycle the valve and check the defrost board operation. Catching a sticky valve in October costs a fraction of replacing a burned-out reversing valve in February.

Geothermal Heat Pump Installation

Geothermal Heat Pump Installation is the highest-efficiency heating and cooling you can put in a Miami home, and it works by pulling or rejecting heat through a ground loop buried in your yard instead of through the outdoor air. In Miami, where the air gets so hot that a standard heat pump has to work hard to reject heat, the cooler underground temperature gives a geothermal system a serious efficiency edge. We handle the full scoping, loop design, and installation, and a geothermal installation in Miami typically runs from $4,130 at the very lowest end to well above $8,850 for a full vertical loop field with the indoor unit, because the drilling or trenching work is site-specific. The payback comes through the monthly electric bill, which drops because the compressor does not have to fight a 95-degree outdoor coil. Marco Benitez has overseen geothermal installs across Miami and will tell you before you spend a dollar whether your lot geology actually supports a loop field.

Horizontal vs. Vertical Ground Loops

A horizontal loop is cheaper to install but requires a larger lot with enough square footage to trench. In neighborhoods like Palmetto Bay or Pinecrest, lot sizes can support that. A vertical loop drills down instead of out, which works on Miami’s smaller urban and suburban lots but adds cost to the job because it requires a drilling rig.

Miami-Specific Efficiency Factors

Miami’s shallow water table and high annual cooling load change the loop sizing math compared to colder climates. Your loop needs to be sized for heat rejection, not heat absorption, which means more loop feet per ton. We calculate that during scoping and include the loop depth and count in the written estimate, so you know what you’re paying for before the drill rig arrives.

Ductless Heat Pump Installation

Ductless Heat Pump Installation is the cleaner way to say “no ductwork required,” and for many Miami ranch houses and older bungalows it’s the most honest retrofit available. A ductless heat pump uses the same building-block tech as a mini split, with an outdoor unit and indoor heads, but we’re talking about whole-home comfort rather than a single problem room. You need it when your home never had central air, when your ductwork is so leaky that you’re cooling your attic, or when you want room-by-room temperature control without tearing out ceilings. We install ductless systems from American Standard, Bryant, and other major brands, and the work falls in the same $4,130 to $8,850 range as all installations, with the final number driven by how many indoor heads and how much refrigerant line we have to run. Every ductless install begins with a room-by-room load calculation, not a rule-of-thumb square footage guess.

Whole-Home Ductless Sizing

Running six indoor heads on a single outdoor unit is possible, but it has to be engineered, not improvised. We check each room’s exposure, window area, and insulation so the heads are matched to real load. A right-sized ductless system uses less power and holds temperature better than an oversized one, which short-cycles and leaves Miami’s humidity in the room.

Condensate Management in Miami Humidity

Every indoor head produces condensate in our climate, because the air is holding water almost all year. The drain lines have to be pitched correctly, and the outdoor unit needs to sit on a pad that keeps it clear of standing water during a summer downpour. Poor condensate handling is one of the most common causes of a failed ductless installation, and we include drain inspection in the job.

Heat Pump Service

Heat Pump Service is a diagnostic and repair call for a heat pump that is making noise, running constantly, blowing warm air in cooling mode, icing up, or tripping a breaker. We get these calls across Miami year-round, and the most common repair bill lands between $175 and $765 depending on the failed part and the system age. Every service call starts with a live person answering the phone, because a compressor running with a bad capacitor is a problem at 2 a.m., not just during business hours. We put the repair price in writing before we turn a wrench, and the repair is guaranteed in writing for a full year. If the same failure comes back inside that year, we return at no charge under the 365-Day Done Right Promise.

Common Miami Heat Pump Failures

We see failed capacitors, contactors with burned contacts, and thermostats that have lost their calibration more than anything else. Humidity adds a second layer: drain clogs and mold in the condensate pan. Salt air near the coast, from North Miami Beach to Coral Gables, accelerates coil corrosion, and that’s why we inspect the coil finish on every Miami service call and flag early pitting before it becomes a refrigerant leak.

Diagnostic Standards We Follow

Every diagnostic follows The Garrison Code, which means we check superheat and subcooling when a system is low on charge rather than just adding refrigerant and leaving. We test capacitors under load, not just with a meter. That’s the difference between a repair that holds and a repair that comes back in six weeks; we do the former and wrap the latter in the free return visit anyway.

Heat Pump Replacement

Heat Pump Replacement is what a homeowner should plan for when the existing heat pump is past 12 years old, is running on R-22 refrigerant, or has a compressor that has failed once and is likely to fail again. We replace heat pumps in Miami with systems sized to today’s heat load, not the load from 1999, and a full replacement runs $4,130 to $8,850 depending on size, efficiency tier, and whether we have to update the indoor air handler and line set to handle modern R-410A or R-454B pressures. A compressor replacement alone is usually not worth it on an old system, because the indoor coil and metering device still carry old-refrigerant design limits. We give you a written fixed price before we order equipment, and we set a firm install date, not a window that spans a week.

R-22 Phaseout and What It Means in Miami

If your heat pump was installed before 2010, there’s a fair chance it runs R-22, and R-22 production ended for good. Refrigerant recharge, if we can even source it, is priced per pound and it adds up fast. Replacing the entire system converts you to modern refrigerant and includes the line set flush, because old oil residue will foul a new compressor if it is not removed properly.

Efficiency and Humid Climate Considerations

Miami forces a choice on heat pump efficiency no one in Ohio has to think about: latent heat, which is the humidity, not the temperature. A system with a variable-speed air handler pulls more humidity out of the air at partial load. That matters in Tamiami and University Park, where the humidity is the part that makes a 78-degree house feel like 84 degrees if the system runs short cycles.

Brands We Service

We’re factory-trained on nine major residential HVAC brands, and heat pumps from York, Daikin, Bryant, and American Standard all come through our Miami install schedule regularly. York units have a strong cost-to-efficiency profile and hold up well in coastal air; we’ve run York heat pumps in homes all the way from Hialeah Gardens to Palmetto Bay without a premature compressor failure when the maintenance schedule stayed on point. Daikin’s inverter-compressor platforms are a strong choice for ductless and mini split work, and we carry their OEM controls and filters so we are not waiting on a regional distributor when a board fails.

Bryant and American Standard both sit in the mid-to-high efficiency tier, and each brand has specific defrost board logic and compressor cutoff settings that a technician either knows or learns on your dime. We know them. Whether you have one of those in the driveway right now or you’re comparison shopping for something else entirely, we can service and install it, and we will hand you a written price before any heat pump work begins in your Miami home. If your current system is beyond repair and you need a full replacement, start with our Heat Pump Installation in Miami guide for what to expect.

Signs You Need a Pro Right Now

• The outdoor unit runs but the indoor air never gets cold. In Miami, this usually means a refrigerant leak, a reversing valve stuck mid-position, or a compressor that has lost its ability to move refrigerant. Letting it run this way costs you full power consumption with zero cooling, and the compressor wears out faster while it spins against a void.
• Your electric bill spiked with no change in thermostat habits. A heat pump that lost its charge, has a restricted filter drier, or a failing run capacitor can pull dramatically more current to do the same work. That bill is not an accident; it is data, and the longer it runs hot, the more parts get heat-stressed.
• The system is iced over in July. Ice on an evaporator coil in cooling mode means low airflow, low refrigerant, or a stuck TXV. All three are repairable if caught early and all three will kill a compressor if you “let it thaw and try again” through the summer.
• You hear a grinding or squealing from the outdoor unit. A failing fan motor or a compressor that has started to wear its bearings is the sound of a part about to fail completely. Replacing a $400 fan motor in July is a better Monday than replacing a $4,000 compressor in August.
• The thermostat reaches set point but the house still feels wet and sticky. That is a humidity problem, which in Miami is a system problem. Short cycling, oversized equipment, or a blower that is not ramping down correctly all leave moisture in the air instead of pulling it out.

Our Process, Step by Step

1. 1
   You call, a person answers. Day or night, a live person picks up the phone at (850) 754-6042. You describe the problem, we ask the right questions, and we schedule a visit inside a stated window, not an all-day wait.
2. 2
   We arrive, introduce ourselves, and diagnose. A background-checked, uniformed technician shows up inside the window and puts eyes on the system. We run a full diagnostic with gauges, meters, and a static pressure check where the problem calls for it, then we write down what we found in plain language.
3. 3
   You get a written price before any work. The price goes on a document in your hand before any wrench turns. No verbal estimates, no additions at the door. If we find something else during the repair, we stop and put that in writing too, because The Garrison Standard does not allow surprise charges.
4. 4
   We do the job by the book. The equipment gets installed or repaired to code, the refrigerant is weighed to the ounce, the electrical is landed and torqued, and the site is left clean. We use nitrogen purge during brazing and pull a proper vacuum before releasing refrigerant, because cutting corners on those two steps is how installs fail early.
5. 5
   You get a written guarantee and a walk-through. Every repair and installation is guaranteed in writing for a full year under the 365-Day Done Right Promise. We walk you through what we did, show you the pressures and temperatures we measured after the job, and answer questions before we leave. If it fails, we come back at no charge.
