AC installation and replacement in Tampa, FL, sized right for your home or business.
A new AC system is a 12-to-15-year decision, and it's the one purchase where the installation matters as much as the equipment. A top-tier unit installed sloppy will underperform, break down early, and cost you more every month — while a mid-range system installed right will run quiet and efficient for years. That's why we treat installation as craftsmanship, not a box swap.
Mendoza Heating and Air handles full AC replacement and new installation across Tampa — residential changeouts, system upgrades, and new construction. We size every system to the house, not to the old unit's label, because half the comfort problems we see trace back to equipment that was never the right size to begin with.
Right now, every split system installation comes with $500 off, a FREE UV light, and a 10-year parts warranty. Free same-day estimates — we'll walk your home, do the math, and give you a straight number.
Estimates are free and same-day: we come out, measure, assess your ductwork and electrical, and give you a written quote — usually within 24 hours of your call. No "we'll get back to you next week."
Once you approve, most residential changeouts are scheduled within days, not weeks — and the install itself typically finishes in a single day. Larger homes, complex ductwork modifications, or commercial jobs can run two days; we'll tell you the timeline before we start, and we don't leave you without cooling overnight unless you agree to the plan first.
On install day, we protect your home — drop cloths, shoe covers, a clean work area — and we haul the old equipment away. Before we leave, we walk you through the new system, the thermostat, the filter schedule, and your warranty paperwork. You should never be left guessing how your own system works.
“I’m not here to sell you the biggest box. Right-sized, installed clean, explained straight — that’s a system that runs for years instead of breaking down.”
Installation is where companies cut corners you'll never see — until the electric bill arrives. Here's what actually matters.
The most common installation mistake in Tampa is oversizing — a 4-ton unit where a 3-ton belongs. Bigger doesn't cool better; it short-cycles, leaves humidity behind, and dies young. We size by load calculation (square footage, insulation, windows, orientation), not by what's already sitting on the pad. If a company quotes you a size without measuring anything, that's your sign to call someone else.
Here's the rule of thumb we give our own family: if the repair costs more than a third of a new system and the unit is over 10 years old, replace it. A $1,500 compressor on a 14-year-old R-22 system is throwing good money after bad — that refrigerant is phased out and every future repair gets pricier. A $250 contactor on a 7-year-old system? Fix it all day.
SEER2 measures efficiency — higher means lower electric bills. In Tampa, where the AC runs eight-plus months a year, the jump from a 14 to a 16+ SEER2 system pays back faster than most people think. But efficiency only delivers if the install is clean: perfect refrigerant charge, sealed ducts, correct airflow. A high-SEER unit on leaky ducts is lipstick on a pig.
We inspect the ducts on every installation quote, because putting a brand-new system on crushed, leaking, or undersized ductwork guarantees disappointment. Sometimes the ducts just need sealing and a few repairs; sometimes a run needs replacing. We'd rather tell you upfront than have you call us in August wondering why the new system "doesn't feel any better."
Old equipment out (and hauled away), new pad or stand set level, line set run or replaced, electrical and drain connected, system vacuumed and charged to spec — then we test everything: temperature split, airflow, controls, safeties. Most homes are done in a day. You'll know it's done right because we show you the numbers, not just the new shiny box.
Every installation we do carries a 10-year parts warranty — but here's what most companies won't tell you: manufacturer warranties require registration and proper maintenance to stay valid. We register your equipment for you and we'll tell you exactly what maintenance keeps the warranty intact. A warranty you can't use is just a brochure.
The honest pricing part: you'll get one written number before we start — equipment, labor, and any ductwork, all itemized. If the quote changes mid-job (it shouldn't, but old houses surprise people), we stop and talk before spending your money. No surprises on the invoice, ever.
Most residential AC replacements are finished in a single day — old unit out, new unit in, tested and running before dinner. Larger homes, ductwork modifications, or commercial jobs can run two days. We'll give you the exact timeline with your quote, and we don't leave you without cooling overnight unless you've agreed to the plan.
It depends on size, efficiency rating, and your ductwork — there's no honest one-number answer without seeing the house. That's why estimates are free: we measure, inspect, and give you a written quote. Right now every installation also carries $500 off plus a free UV light.
Higher SEER2 means lower electric bills, and in Tampa's long cooling season the payback is real. We'll show you the options for your home and the honest math on each — but remember, a high-efficiency unit only delivers on leaky ducts if the ducts get fixed too.
We install and service all major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Amana, and more. We'll recommend based on your budget and the house, not on which brand pays us the best spiff.
Yes — old equipment, packaging, and job debris all leave with us. Your yard and home look like we were never there, minus the new system humming quietly outside.
Not always — but we inspect it on every quote. If your ducts are crushed, leaking, or undersized, a new system can't perform on them, and we'll show you exactly what we found. Sometimes it's a sealing and repair job, not a full replacement.
Yes — every installation includes a 10-year parts warranty, and we register the equipment for you so it's actually valid. We'll also tell you what maintenance keeps it intact, because manufacturers require it.
