Cool the room you're actually in — garage, lanai, addition, or the whole house — without ductwork you don't have.
A mini-split — also called a ductless system — is simple in concept: one outdoor unit connected to one or more slim indoor heads mounted on the wall or ceiling, linked by refrigerant lines that pass through a hole about three inches wide. No ducts, no tearing open ceilings, no cooling the whole house to fix one hot room. Each head runs independently, so the temperature in the garage workshop doesn't have to match the temperature in the nursery.
Tampa is built for these systems. Enclosed lanais, converted garages, bonus rooms over the garage, older homes that were built before central air existed — this housing stock is full of spaces that ductwork can't reach or was never designed for. Mini-splits were practically invented for exactly those rooms, and modern inverter models do it while using a fraction of the electricity a window unit burns.
Mendoza installs and services mini-split systems across Tampa — single-zone installs for one problem room, multi-zone setups for whole homes, and repairs on systems other companies put in. Every install is sized room by room, permitted, and quoted in writing before any work starts.
These are the calls where a ductless system isn't just an option — it's the best tool for the job.
“One outdoor unit, a head in each room, and you cool the spaces you’re actually living in. No ducts means no duct loss — that’s real efficiency, not a brochure number. But I’ll tell you straight: if the whole house needs cooling and your ducts are in good shape, a central system is usually the smarter money. Mini-splits win when the space is the problem.”
We install both, so we don't need to sell you either one. Here's how the decision usually shakes out.
The space has no ducts and adding them would mean construction. The main system is fine but one room never cools. You're adding square footage — a suite, an office, a converted garage — and upsizing the whole central system for it would be wasteful. Or you want genuine zone control: bedrooms cool at night, living spaces cool during the day, unused rooms barely running. That's mini-split territory.
The whole house needs a new system anyway and the ductwork is in good condition. Running one central system is simpler and, at whole-house scale, often cheaper than five mini-split heads. We'd rather quote you the central replacement and lose the mini-split sale than put ductless heads in a house that's a textbook central-air job — and we'll show you both sets of numbers if it's genuinely close.
They're cheap to buy and expensive to own: loud, power-hungry, hard on humidity, and they leave a window open to the world. A mini-split costs more up front and then outclasses them on every measure — quieter, far cheaper to run, real humidity control, and it heats in winter too. For a room you use every day, the math catches up fast.
And the honest pricing part: a mini-split quote depends on how many zones you need, what capacity each room calls for, how far the lines run, and whether your panel has room for the circuit. As a frame, a single-zone install for one room usually lands in the low-to-mid thousands installed; a whole-home multi-zone system costs more and can approach central-air money. That's why the in-home quote matters — it's exact, it's in writing, and it's free.
Room by room, with a real load calculation — square footage, ceiling height, windows, sun exposure, insulation, and what's in the room (a garage workshop needs more than a bedroom). Rules of thumb get us a starting point, but Tampa sun on a west-facing lanai changes the math. Oversized short-cycles and leaves humidity behind; undersized can't keep up in August. We size it before we quote it.
Most residential multi-zone outdoor units run two to five indoor heads, each with its own temperature control — that's the zone control mini-splits are famous for. A single room pairs one head to one outdoor unit. We'll tell you honestly whether one multi-zone unit or separate systems make more sense for your layout.
Very — for two reasons. Their inverter compressors ramp up and down instead of slamming on and off, and there are no ducts. Ductwork running through a hot Tampa attic leaks and absorbs heat, so a meaningful share of the air a central system cools never reaches the room. A mini-split delivers its cooling directly into the space, and you only cool the zones you're using.
Expect 15 to 20 years from a quality system that's maintained — comparable to central air. The homeowner part is simple: rinse the washable filters monthly. The professional part is an annual check of refrigerant, drains, and electrical, which keeps efficiency up and the warranty in good standing.
Yes — a mini-split install involves mechanical and electrical work, and Tampa and Hillsborough County require permits for it. We pull the permits and handle the inspection as part of the job. Skipping them can cause real problems with insurance and with selling the home later, so we don't skip them.
The major brands offer long parts warranties — commonly 10 to 12 years when the system is registered after install. We handle the registration paperwork for you, and our installation workmanship is covered by us. The exact warranty for the equipment you choose is spelled out in writing on your quote, before you decide.
It depends on the job: how many zones, what capacity each room needs, how far the refrigerant lines run, and whether your electrical panel needs work. As a frame, a single-zone install for one room usually lands in the low-to-mid thousands installed, while whole-home multi-zone systems cost more and can approach central-air money. Your in-home quote is exact, in writing, and free.
