What this work looks like done right
A typical duct system leaks a meaningful share of everything the air conditioner makes, and in Florida the insult is doubled: the cooling you paid for escapes into a 130-degree attic, and on the return side that attic air, hot, humid and dusty, gets pulled into the system and delivered to your living room. Sealing the ducts is plugging a hole in your own pocket.
Sealing here is done with mastic and proper mechanical fastening at every accessible connection: boots to registers, collars at the plenum, joints along every run, and the return side, which leaks worse and matters more. Cloth tape and wishful thinking are not sealing materials, whatever the last guy thought.
The results are measurable and you get the measurements: static pressure and register airflow before and after, plus the things you feel without instruments, rooms that even out, humidity that settles down and a system that cycles instead of grinding all afternoon.
- Mastic sealing at every accessible joint
- Return-side leaks prioritized, they matter most
- Boots, collars and plenum connections secured
- Filter rack bypass leaks closed
- Before-and-after measurements provided
- Often the best efficiency spend in the house
Three steps, no surprises
Measure the leakage story
Static pressure, register readings and an attic inspection establish the baseline.
Seal it properly
Mastic and mechanical fastening, joint by joint, supply and return both.
Show the difference
The same measurements after, so the improvement is a fact instead of a feeling.

Get a Straight PriceWhy this work is different in Florida
Heat is the obvious opponent here, but humidity is the sneakier one. It swells door seals, feeds biological growth on evaporator coils, corrodes electrical contacts and keeps drain lines permanently busy. A system can lose a fifth of its capacity to a dirty coil without a single dramatic symptom beyond a power bill that keeps creeping and a house that never feels quite crisp. That slow rot is why the tune-up exists, and why we measure temperatures and pressures instead of just rinsing the condenser and calling it a day. The goal is a system that pulls its rated capacity in August, not just one that turns on.
How pricing works
Pricing here works one way: you hear the number before the work happens. Service calls get quoted when you book. Repairs get diagnosed, then priced, then approved by you before a wrench turns. Replacements come as two or three clear options with honest operating cost differences, not a single take-it-or-leave-it figure engineered around a commission. The word customers keep using in reviews is honest, and that is the entire strategy: an owner-run company in a small market lives or dies on whether the last customer would call again, so every price has to survive being repeated to your neighbor.
The owner-run difference
Owner-run means something specific here. The person who answers the midnight call, quotes the price and stands behind the guarantee is the same person whose name is on the truck. There is no call center reading a script, no commissioned closer arriving after the technician softens you up, and no corporate playbook that treats a repair visit as a sales lead. Twenty years of hands-on work set the standard; four years of running the company on referrals have proven it pays.
Brands, parts and honest recommendations
On the equipment side, Rheem and Trane are the factory relationships, which means preferred access to units, parts and technical support when your job needs them. On the repair side, brand loyalty means nothing: Carrier, Goodman, Lennox, Daikin, York, Ruud, Amana and the rest of what Florida installs are everyday work, and regional parts availability for all of them keeps repair turnarounds short. The recommendation you get is driven by what fits the house and the budget, never by whatever box a distributor wants moved this month.
Before the truck arrives
Want the visit to go faster? Three things help. First, note what the system is doing and when it started: sounds, smells, warm air, water where it should not be. Second, check the breaker panel and the filter before calling, because a tripped breaker or a suffocated filter solves a surprising share of calls on the phone, free. Third, clear a path to the equipment, indoor and out. None of it is required, but customers who do it tend to have their answer, and their cool air, sooner.
Questions we hear about this
Straight answers about duct sealing from the crew that does it every week. If your question is not here, call 561-339-5729 for a direct answer, day or night.
How much cooling do leaky ducts actually lose?
Enough that duct sealing routinely outperforms equipment upgrades dollar for dollar in Florida homes. The exact figure depends on your system, and the before-and-after measurements will tell you what was recovered.
Why do return leaks matter more?
Because they pull attic air in: hot, humid, dusty and occasionally flavored by whatever lives up there. Supply leaks waste cooling; return leaks waste cooling and contaminate the house air at the same time.
Is aerosol duct sealing a real thing?
It exists and has its uses, mostly for inaccessible runs. Accessible ductwork gets better, cheaper and more verifiable results from hand sealing with mastic. You get the honest recommendation for your situation, not the fancier invoice.
Will sealing help my allergies?
It often helps noticeably, because sealed returns stop pulling attic dust and fiberglass into the airstream. Pair it with the right filtration and the indoor air changes character.
How long does duct sealing last?
Mastic done right is effectively permanent, decades, not seasons. It cures into the joint rather than sticking onto it, which is exactly why it beats every tape ever made in an attic.
