Garage conversions
The most common request I get in Ocala. Home gyms, workshops and offices in the garage. Insulate the door first, then size for the real heat load. Usually 12,000 to 18,000 BTU for a two-car space.
Ductless cooling for the rooms your central system never reached
Ocala AC Repair Pros installs and services single-zone and multi-zone ductless mini-split systems throughout Marion County. Mini-splits cool spaces that have no duct access: garages, workshops, additions, converted lanais, Florida rooms, sunrooms and detached buildings. Installation includes a dedicated circuit, proper line set and full vacuum and charge.
Nearly every Ocala home has one room that never gets comfortable. The bonus room over the garage. The lanai somebody enclosed in 2011 without extending the duct system. The workshop out back. The master bedroom on the west side that runs five degrees warmer than the rest of the house every afternoon.
Extending ductwork to those spaces is expensive and often physically impossible. A mini-split solves it with a single three-inch penetration through the wall.
Where mini-splits make sense in Marion County
Enclosed lanais & Florida rooms
Extremely common in The Villages and Silver Springs Shores. These spaces were built as screen porches, then glassed in. They have enormous solar gain and no ductwork whatsoever.
Room additions
An addition tied into an already-marginal duct system starves the rest of the house. A dedicated mini-split leaves the original system alone and gives the new room its own thermostat.
Workshops & detached buildings
Barns, tack rooms and shops on the horse properties west of Ocala and near the World Equestrian Center. No practical way to run duct, plenty of reason to cool.
The one hot bedroom
Cheaper than redesigning a duct system to fix one room. Gives that occupant independent temperature control, which quietly resolves a lot of household arguments.
Whole-house ductless
Multi-zone systems for older Ocala homes where adding ductwork means opening walls and ceilings. Four to five indoor heads on a single outdoor condenser.
Sizing a mini-split for Florida heat
Mini-split sizing charts published by manufacturers assume a conditioned, insulated space in a moderate climate. Ocala is neither. An uninsulated garage with a steel door facing west has two to three times the heat load per square foot of a bedroom the same size.
| Space | Approx. size | Typical capacity | Watch for |
|---|---|---|---|
| Bedroom or office | 150 to 300 sq ft | 9,000 BTU | West-facing glass |
| Enclosed lanai | 200 to 400 sq ft | 12,000 BTU | Solar gain through glass, poor ceiling insulation |
| Two-car garage | 400 to 600 sq ft | 12,000 to 18,000 BTU | Uninsulated door, attic heat, vehicle heat soak |
| Large addition | 400 to 700 sq ft | 18,000 to 24,000 BTU | Ceiling height, number of exterior walls |
| Detached workshop | 600 to 1,000 sq ft | 24,000 to 36,000 BTU | Insulation level, door openings, equipment heat |
These are starting points, not quotes. The actual number comes from a walkthrough that accounts for insulation, orientation, glazing and how the space gets used.
What a correct mini-split installation requires
Most mini-split failures I get called out to fix are installation failures, not equipment failures.
Done right
- Deep vacuum to 500 microns and a decay test held before releasing refrigerant
- Flare connections torqued to manufacturer specification
- Line set properly sized for the run length, with charge adjusted for it
- Dedicated circuit and disconnect installed to code
- Condensate routed with proper fall, or a pump where gravity will not work
- Permit pulled and inspection passed
What I get called to fix
- DIY units that were never evacuated, so moisture is circulating in the system
- Overtightened flares that crack and leak six months later
- Long line runs with no added charge, producing weak cooling from day one
- Condensate draining onto the slab, into a wall cavity, or straight down the exterior
- Units powered off a shared circuit that trips under load
- Wall heads mounted too low or directly over furniture
Pre-charged DIY kits are genuinely tempting on price. The failure rate on them in this market is high enough that I will service one, but I will not warranty somebody else's flare connections.
★★★★★
I enclosed my lanai two years ago and it was unusable from May through September. He talked me out of the 9,000 BTU unit I had picked out online, explained the glass was going to eat it alive, and put in a 12,000. Room holds 74 in August now. Should have done it the first summer.
Mini-split and ductless AC questions
How much does mini-split installation cost in Ocala?
A single-zone mini-split installed in Ocala typically runs $3,400 to $5,800 depending on capacity and line set length. A two-zone system runs $6,200 to $9,500. Multi-zone systems covering three or four rooms land between $9,000 and $16,000 installed with electrical work included.
The biggest cost variables are line set run length, whether a new dedicated circuit is required, and mounting height. A garage unit twelve feet from the panel is far cheaper than a second-floor bedroom with a fifty-foot run. Full ranges are on the cost page.
Is a mini-split good enough to cool an Ocala garage?
Yes, if it is sized for the heat load rather than the floor area. An uninsulated Ocala garage with a west-facing door needs roughly double the capacity of a conditioned room the same size. A 12,000 BTU unit handles most two-car garages once the door is insulated.
Skipping garage door insulation is the most common reason these installations disappoint. A bare steel door on the west side radiates heat all afternoon and the mini-split spends its entire capacity fighting it. Insulating the door first often lets you buy a smaller, cheaper unit.
Can a mini-split replace central air in a whole house?
It can, using a multi-zone system with an indoor head in each area. In practice, most Ocala homes with existing ductwork are better served by central air. Mini-splits win where there is no duct access: additions, garages, lanai conversions, workshops and Florida rooms.
Whole-house ductless makes real sense in older Ocala homes near the downtown historic district where adding ductwork means tearing into plaster, and in additions that were built without a duct run. Zone-by-zone control is a genuine advantage. Multiple wall heads are a genuine aesthetic tradeoff.
