Load calculation and sizing
We run a Manual J load calc on the space, not a guess based on square footage. That's how we avoid the two most common ductless problems: a system that short-cycles and one that never keeps up in August.

What's included in a mini split install
Every install we do includes the same core scope. If you need electrical work, permits, or a ceiling cassette instead of a wall head, we'll quote that separately and tell you upfront.
Indoor and outdoor mounting
Wall bracket or ceiling mount for the head, concrete pads or wall brackets for the condenser. We level everything, torque the flare fittings to spec, and seal the wall penetration so water and pests stay out.
Line set and drain routing
Copper line set, communication cable, and PVC drain line run through a single 3-inch penetration. We slope the drain correctly so condensate flows out instead of pooling in the pan and growing mildew.
Vacuum and refrigerant charge
Deep vacuum to 500 microns, 15-minute hold test, then weigh in additional R-410A or R-32 on a refrigerant scale. We verify pressures with manifold gauges and log the numbers for your records.
Commissioning and walkthrough
We run the system through a full cooling and heating cycle, check temperature split at the supply and return, and show you how to clean the filters. You get the manual, warranty card, and our direct number.
Ductless mini split Orlando FL: what the work actually involves
A ductless mini split Orlando FL system pairs one outdoor condenser with one or more wall-, ceiling-, or floor-mounted air handlers, connected by a copper line set and a PVC drain line instead of ductwork. Each indoor head has its own thermostat, so you cool the room you're in and leave the rest alone. We mount the indoor unit, drill a 3-inch penetration for the line set, pull a vacuum to 500 microns, weigh in R-410A or R-32 refrigerant on a scale, and commission the system with manifold gauges.
Orlando homes built before 1990 often have duct leakage of 20 to 30 percent, which is exactly why ductless AC Orlando FL keeps coming up in conversations with homeowners in College Park and Audubon Park. If your back bedroom runs 6 degrees warmer than the living room, or your garage conversion never got tied into the central system, a mini split is the fix. We've been installing and servicing these systems since 1982, and we've watched them go from niche to standard across Orange County.

Tools and methods we use
Tools & Equipment
Manifold gauges
Used to read high-side and low-side refrigerant pressures during commissioning and diagnosis. We compare readings against the manufacturer's charging chart to confirm the system is dialed in.
Vacuum pump and micron gauge
Pulls the system down to 500 microns and holds it for 15 minutes. This is the single most important step in a mini split install, and skipping it is why cheap jobs fail early.
Refrigerant scale
We weigh in additional R-410A or R-32 by the ounce when line set length exceeds the factory charge. Guessing here means the system runs wrong from day one.
Leak detector and nitrogen regulator
Pressure-testing with nitrogen and an electronic leak detector finds flare and braze leaks before they cost you a compressor. We do this on every repair and every install.
Clamp meter and multimeter
Used to check amp draw on the compressor and fan motors, test capacitors, and verify control board voltage. Most no-cool calls get solved with these two tools.
Flaring tool and torque wrench
Flare fittings on mini splits have to be perfect. We use a precision flaring tool and torque every connection to the manufacturer's spec in foot-pounds. Over-torqued flares crack; under-torqued flares leak.
Fin comb and coil cleaning pump
Straightens bent condenser fins and pushes cleaning solution through the evaporator coil. In Orlando's pollen season, coils need this once a year to keep airflow up.
Methods & Standards
ACCA Manual J load calculation
We calculate the actual heating and cooling load of each space based on square footage, insulation, window area, and orientation. This is how we size the head correctly instead of guessing. Undersized systems never keep up; oversized systems short-cycle and don't remove humidity.
EPA Section 608 refrigerant handling
Every technician who touches refrigerant on your system holds EPA Section 608 Universal certification. That means recovery, evacuation, and charging are done to federal standards, and the refrigerant doesn't end up in the atmosphere.
Deep vacuum to 500 microns
We pull the system down and hold it for 15 minutes. If it rises above 500 microns during the hold, there's moisture or a leak, and we don't proceed until it's fixed. This single step separates a system that lasts 15 years from one that lasts 3.
AHRI-matched system pairing
We pair condensers and air handlers that carry AHRI certification together. Mismatched equipment voids manufacturer warranties and runs at lower efficiency. Our pairings are documented and submitted with your warranty registration.
When a ductless mini split makes sense
01
You converted a garage or attic into living space, but the central system doesn't reach it.
What we do: We install a single-zone mini split sized for the square footage and insulation of the new space. Line set runs through the nearest exterior wall, condenser sits on a pad outside. No ductwork, no tying into the existing system.
→ The new room holds its own temperature year-round, and your central system stops working overtime trying to condition a space it was never designed for.
02
One bedroom upstairs is always 6 to 8 degrees warmer than the rest of the house.
What we do: We add a single ductless head in that room and let it handle its own load. The central system keeps running for the rest of the house, and the mini split picks up the slack where duct pressure was never adequate.
→ The hot room becomes the coolest room, and you stop fighting the thermostat every night. Most homeowners see a 10 to 15 percent drop in cooling costs.
03
You're building a detached workshop, studio, or pool house and need AC and heat.
What we do: A single-zone heat pump mini split handles both. We run a 240V circuit if needed, mount the indoor head, and set the condenser on a pad. One system, year-round comfort, no separate furnace.
→ You get a conditioned outbuilding for about the cost of a window unit plus a space heater, but it actually works and doesn't look like a dorm room.
04
You rent out a portion of your home and want separate temperature control.
What we do: We install a multi-zone system with independent heads for each space. The tenant controls their zone, you control yours, and neither of you touches the other's thermostat.
→ Clean separation, no arguments over the thermostat, and each zone only runs when someone's there. Rental-friendly and code-compliant.
How ductless works in Orlando specifically
Orlando's climate is the easy part: mild winters, long cooling season, and humidity that runs 70 to 90 percent from May through September. That humidity is what shapes how we design ductless systems here. We size heads to run longer cycles so they pull moisture out of the air instead of short-cycling and leaving the room clammy. Older homes in College Park and Audubon Park often have no ductwork at all, or ductwork that's leaking 25 percent of its air into the attic. A ductless mini split Orlando FL install sidesteps that entirely. Newer construction in Lake Nona and Horizon West is tighter, so we pay attention to fresh-air ventilation and make sure the system isn't oversized for a well-sealed room. We also deal with the practical side: HOA approvals for outdoor condenser placement, 240V circuits in older panels, and condensate routing that won't freeze or clog. If you're comparing the cost to install ductless mini split Orlando FL against patching a failing central system, we'll run both numbers for you.
Neighborhoods We Serve
-
College Park
Mostly 1940s to 1960s bungalows with no existing ductwork. Ductless is often the only practical way to add AC to a converted porch or addition.
-
Lake Nona
Newer, tighter construction. We size systems carefully here because oversized units short-cycle and don't remove humidity in well-sealed rooms.
-
Baldwin Park
HOA rules govern outdoor equipment placement. We know the typical approval process and can position condensers to pass review on the first submission.
-
Winter Park
Historic homes with plaster walls and no attic space for ducts. Wall-mounted mini split heads avoid the need to open up walls or run new duct chases.
-
Dr. Phillips
Larger homes with bonus rooms and pool houses that central systems don't reach. Multi-zone ductless setups are common here.
Local Conditions We Plan For
-
High humidity from May through September
Systems must be sized to run long, steady cycles so they dehumidify. Oversized equipment cools the air fast but leaves moisture behind, which feels clammy and grows mildew.
-
Older homes with no existing ductwork
Ductless is often the only option that doesn't involve tearing out walls or running new chases. We route line sets through exterior walls and closets to minimize visible work.
-
Hurricane season from June through November
Outdoor condensers need proper anchoring and clearance from debris. We mount on pads or brackets rated for wind loads and advise on pre-storm shutdown procedures.
-
Mild winters with occasional hard freezes
Heat pump mini splits handle Orlando winters easily, but we check defrost boards and reversing valves before the first cold front so you're not caught off guard in January.

Mini split problems we fix in Orlando
Ductless systems are reliable, but they're not immune to Florida heat and humidity. Here are the issues we see most often and how we handle them.
Problem
Indoor head freezes up or ices over
A frozen evaporator coil means low refrigerant or restricted airflow. Run it like that and the compressor overheats, turning a $300 repair into a $1,800 replacement.
Our Fix
We recover the charge, pressure-test with a leak detector, repair the flare or braze joint, then evacuate and weigh in fresh refrigerant. We also check the blower motor and filter to rule out airflow problems.
Problem
Water dripping down the wall from the indoor unit
A clogged PVC drain line backs condensate into the pan and onto your drywall. In Orlando's humidity, that line can clog in under a year if it isn't flushed.
Our Fix
We clear the line with a vacuum, flush it with a drain treatment, and verify the slope. If the pan is cracked or the float switch is stuck, we replace those parts the same visit.
Problem
System runs but doesn't cool the room
Could be a failed capacitor, a stuck reversing valve, or a dirty coil. Left alone, the compressor runs hot and eventually fails, and that's the most expensive part in the system.
Our Fix
We test the capacitor with a multimeter, check the reversing valve operation, and clean the evaporator and condenser coils. Most no-cool calls trace back to one of those three, and we fix it on the first visit.
Problem
Outdoor unit won't turn on at all
A tripped breaker, a failed contactor, or a bad control board. If it's July, you're looking at a miserable night and possibly a hotel bill.
Our Fix
We diagnose the electrical side with a clamp meter and multimeter, replace the failed component, and verify amp draw against nameplate. We carry contactors and boards for the major brands on the truck.
Why Orlando homeowners go ductless
Ductless systems solve specific problems that central air can't touch. Here's what you actually get when we install one in your home.
-
Zone-by-zone control
Each indoor head runs independently, so you can cool the master suite to 72 and leave the guest room at 78. That kind of zoning typically trims 15 to 25 percent off cooling costs in Orlando homes where one or two rooms were always fighting the thermostat.
-
No ductwork, no losses
Duct leakage in older Orlando homes wastes a quarter of the air you're paying to cool. A mini split delivers refrigerant straight to the room, so every BTU lands where you want it. That's why mini split installation Orlando homeowners ask for is often cheaper to run than patching a leaky duct system.
-
Heat when Florida turns cold
Ductless heat pumps run in reverse to heat your home when a January cold front drops Orlando into the 30s. No resistive strip heat, no $400 electric bill. Modern inverter compressors hold capacity down to 5 degrees Fahrenheit, which covers every cold snap we've seen in 44 years.
-
Quiet, filter-friendly air
Indoor heads run at 19 to 34 decibels, quieter than a refrigerator. Washable air filters pull out dust and pollen, and a ductless heating and cooling Orlando setup doesn't recirculate the allergens that build up in old flex duct. For allergy sufferers in Lake Nona, that alone justifies the install.

Installed a three-zone mini split in our Lake Nona home. Crew was on time, clean, and walked us through everything. The vacuum hold test and refrigerant weigh-in were documented on the invoice, which no other contractor even mentioned. Six months in, zero issues.
Yelp ★★★★★4.8
Our mini split stopped cooling in July. They came out the same day, found a leaking flare, repaired it, and recharged the system. Fair price, no upsell. I've used them twice since for maintenance and both visits were solid.
BBB ★★★★★4.9
We manage several rental properties and have used them for ductless installs and repairs. They answer the phone, show up when they say, and their pricing is consistent. That's rare in this trade. Highly recommend for any Orlando landlord.

What Orlando customers say
Real experiences from customers who chose our Ductless Mini-Splits services.
“Our 1950s bungalow had one room that never cooled. The team installed a single-zone mini split in about five hours, ran the line set clean through the closet, and patched the wall like they were never there. That room now holds 72 degrees when it's 96 outside. Electric bill dropped $47 the first month.”

Marisol R.
Homeowner, College Park
“We converted the garage into a home office and needed cooling that didn't involve tearing up the house. They sized a 12,000 BTU unit, pulled the vacuum to 500 microns, and walked me through the whole thing. Six months in, zero issues. The follow-up call at 30 days was a nice touch.”
D
Derek T.
Homeowner, Lake Nona
“We manage six rental units and two of them had mini splits that kept freezing up. Their tech found a refrigerant leak at a flare, repaired it, weighed in new R-410A, and had both units cooling the same afternoon. Fair pricing and they actually answered the phone.”

Frequently asked questions about ductless mini splits in Orlando
Real answers to the questions we hear most often from local homeowners and property managers.
How much does a ductless mini split cost in Orlando FL?
Most single-zone installs run $3,200 to $5,800 in 2026, including equipment, line set, and labor. Multi-zone systems with three or four heads land between $7,500 and $14,000. The cost to install ductless mini split Orlando FL varies with line set length, whether you need a 240V circuit run, and which brand you pick. We quote the full job upfront.
Who installs mini splits in Orlando Florida?
You want a licensed Florida HVAC contractor with EPA Section 608 certification, not a handyman. We've been doing this in Orlando since 1982, and we handle the load calculation, the electrical, the vacuum, and the refrigerant charge. We also pull any permits Orange County requires for the work.
Are ductless mini splits good for Orlando homes?
Yes, and especially for older homes with leaky ducts or additions that never got tied into central air. The mild winters mean the heat pump side gets real use too. Our humidity is the one thing to plan for: we size systems to run longer cycles so they pull moisture out instead of short-cycling.
How often should mini splits be serviced in Orlando?
Twice a year: once in spring before cooling season and once in fall before heating season. Orlando's pollen and humidity clog filters and grow biological film on evaporator coils fast. A mini split cleaning Orlando Florida visit runs $149 to $229 and includes coil wash, drain line flush, and a refrigerant pressure check.
