Actually Local

New homes, real physics.

A new home doesn't mean a premium AC — builders install to a budget, and by year three to five we're often correcting rushed line sets, marginal charges, and duct shortcuts across Laureate Park and Storey Park. We diagnose with digital gauges, integrate with your smart thermostats instead of fighting them, and keep the documented maintenance your warranty requires.

✓

Precise Diagnosis · Expert Repair

AC repair in Lake Nona — the failures we see every week.

Lake Nona failures skew young: builder shortcuts surfacing at year 3–5, smart thermostats misconfigured for the equipment behind them, and duct runs that never matched the load calc. Our gauges find:

Most Common

Weak or blown capacitors

The #1 summer breakdown in Central Florida — and one of the cheapest fixes when caught early at a tune-up.

Book a Repair →

Turn It Off First

Frozen evaporator coils

Usually a clogged filter, low charge, or choked return air. Ice on your lines? System OFF, fan ON before you call — it can save your compressor.

Why It Freezes →

Bigger Decision in 2026

Refrigerant leaks

R-410A is being phased out, so a refrigerant repair on an older system deserves honest math. We show you the numbers before you approve anything.

The Honest Math →

Central Florida Storms

Storm & surge damage

Afternoon storms are hard on control boards and condensers. We test components — we don't guess and replace.

Get It Checked →

Smart-home owners: Ecobee, Nest, communicating systems — we configure them to the actual equipment and airflow, so the tech in your walls finally matches the tech on them.

Preventive Maintenance · Protect Your Investment

The cheapest repair is the one you never need.

A $29 "tune-up" is a sales visit with a flashlight. Ours is a full inspection with instruments — and every visit includes drain line cleaning & treatment (a service often billed separately elsewhere) plus a written report documenting your system's condition.

Every Maintenance Visit Includes

Measured & Documented

Cooling & heating operation check
Compressor operation + current draw measured
Electrical connections tightened
Contactor & starting components inspected
Compressor protection tested
Refrigerant operating pressures verified
Refrigerant lines inspected for visible leaks
Outdoor condenser coil inspected
Drain line cleaned + treated — included
Written condition report after every visit

Why the drain line matters: clogged drains are Florida's #1 nuisance breakdown, and drain cleaning alone runs $150–$180 à la carte. We include it in every single visit. Measured, never guessed.

Installation & Replacement

New AC installation in Lake Nona, priced straight.

When a Lake Nona system does need replacing, it's a chance to fix what the builder skipped — real load calculation, proper line sets, equipment matched to the home instead of the budget sheet. Two things matter more than the brand on the box: correct sizing (an oversized unit short-cycles and leaves your house cold but clammy) and honest pricing.

Good / better / best, on one pageEvery replacement quote comes with real numbers — and which option we'd choose for our own home.

Sized for your home, not the saleLoad calculation first. Right-sized systems cost less to run every month for 15 years.

Rebates & $0-down financingWe flag any FPL, Duke, or TECO rebates your equipment qualifies for — and never sell you a credit that doesn't exist.

Outstanding service — truly lives up to the name "Fast Service"! My AC stopped cooling properly on a Friday afternoon. I called and they had a technician at my house the very next morning, Saturday. Professional, knowledgeable, and the problem was fixed quickly.

I needed help in a moment of urgency and they were extremely fast and helpful — they solved my problem in hours. Later, when I had another adjustment needed, they quickly sent a technician. I was always very satisfied with the service and professionalism. I highly recommend.

2-minute hurricane prep for your AC — before the storm hits.

Shut the system off at the breaker before landfall — a surge can fry the electronics. Clear loose debris around the condenser. And if it took water, don't flip it back on until it's checked. Heat safety: see the National Weather Service and CDC heat guidance.

Refrigerant Transition · 2026

R-410A is being phased out. What it means for your Lake Nona home.

New systems now ship with R-454B, and repairing older R-410A systems gets pricier every season. Here's the honest math on when a refrigerant repair still makes sense — and when it doesn't.

Why is my AC freezing up? The 4 causes we see most.

Ice on your lines in July looks bizarre, but it's our most common call. First move: system OFF, fan ON — running it frozen can kill the compressor. Then check the filter. Here's the rest.

Money · Rebates & Credits

That $2,000 AC tax credit? It expired. Here's what still saves you money.

The federal 25C credit ended Dec 31, 2025 — no matter what the ads imply. What's real in 2026: FPL/Duke/TECO rebates, $0-down financing, and correct sizing. We'll never sell you a credit that doesn't exist.

Lake Nona FAQ

Good questions. Straight answers.

Builder-grade is real: equipment and installs done to a budget under time pressure. Marginal refrigerant charges, rushed duct runs, and misconfigured thermostats all surface in years 3–5. We measure, show you the readings, and fix the actual cause.

Yes — Ecobee, Nest, Honeywell, and communicating OEM controls. Misconfiguration is one of the most common 'failures' we find in Lake Nona.

The opposite — most manufacturer warranties require documented annual maintenance. Our written, measured reports are exactly that documentation.

Laureate Park, Northlake Park, Village Walk, Storey Park, Randal Park, and the Medical City area — 32827 and 32832.

We measure first with digital gauges and give you the exact price before any work begins. Warranty-covered parts are flagged as such — you shouldn't pay for what the manufacturer owes you.
