Licensed HVAC professionals serving West Palm Beach since 1988.
ENERGY STAR estimates that 20% or more of the air moving through a typical duct system is lost through leaks, holes, and poor connections. In Palm Beach County, where air conditioning runs for 10 or more months per year, those losses translate directly into hundreds of dollars in wasted energy annually and an AC system that works far harder than it should.
At Hopkins Air Conditioning, whether your home has a single leaking joint or an entire section of deteriorated flex duct, our team identifies the problem precisely and corrects it permanently.

Duct problems rarely announce themselves with an obvious failure. More often, they show up as rooms that never cool down, no matter how long the AC runs, energy bills that creep higher month after month, or persistent dust near your supply registers. In South Florida's high-humidity climate, deteriorated duct insulation in unconditioned attic space creates a secondary problem: warm, moist air infiltrates the system and raises the humidity load on your entire home.
Our team is trained to track down these hidden losses using calibrated diagnostic equipment rather than guesswork, so we repair what is actually failing rather than what is merely visible.
Scott E. of West Palm Beach has been using Hopkins Air for four years. His experience included both AC repairs and a full whole-house ductwork installation. He wrote in December 2025:
"Whether its been fixing issues with the AC units or installing new ductwork for the whole house (what a big difference that made in all the rooms, well worth it) they always do a good job. Highly recommended!"
That commitment to consistent quality runs through every ductwork repair we perform. We show you exactly what we find, explain what it means for your comfort and energy costs, and let you make an informed decision before any work begins. Explore our full ductwork services.
We follow a structured, six-step repair process on every job to ensure nothing is missed and every result is verified with data.
Step 1: Duct blaster pre-test. Before touching anything, we pressurize your duct system using a duct blaster, a calibrated fan that measures total air leakage to establish a baseline we will compare against after repairs.
Step 2: Visual and camera inspection. We perform a hands-on visual inspection of all accessible duct runs and use a duct inspection camera to identify disconnected sections, crushing, or mold inside ducts that are not accessible from registers.
Step 3: Static pressure measurement. We use a static pressure gauge to measure airflow resistance across the duct system, which identifies restrictions caused by collapsed or undersized duct runs that are reducing delivery to specific rooms.
Step 4: Repairs, sealing and reconnection. We apply mastic sealant at leaking joints and seams rather than relying on standard duct tape, which degrades in South Florida's heat. Disconnected flex duct runs are reconnected with mechanical fasteners and sealed. Crushed or kinked sections are straightened or replaced.
Step 5: Flex duct and insulation replacement. Where flex duct is damaged beyond repair or duct insulation has deteriorated, we replace those sections completely. This step is particularly important in older Palm Beach County homes where original duct materials may be decades past their useful life.
Step 6: Post-repair duct blaster confirmation test. We re-run the duct blaster test after all repairs are complete to confirm that leakage has been reduced to an acceptable level. You receive a written copy of both test results.
When a homeowner called Hopkins after a storm left them with an AC that would not cool properly, the team discovered the real issue went beyond the equipment. David and Chuck, who were on call, walked the customer through what the storms in the area could have done to their system and helped them understand the next steps. P I. of West Palm Beach wrote in December 2025 that she "cannot say enough about Hopkins Air Conditioning" and that the experience had started months earlier when the AC stopped cooling. That kind of communication matters most when the cause turns out to be duct damage that is easy to miss without a proper inspection.
At Hopkins Air Conditioning, we do not consider a ductwork repair complete until we can prove it worked. Every repair job includes a pre-repair duct blaster test to quantify total system leakage before we begin and a post-repair duct blaster test to confirm that leakage meets or exceeds current Florida Building Code requirements. We document both test results in writing and provide you with a copy before our technician leaves your property.
Leaking ducts in an unconditioned attic create a compounding problem unique to South Florida's climate. Conditioned air escaping into an attic that reaches 130 to 150 degrees forces your AC to run longer while hot, humid outdoor air infiltrates through those same gaps, increasing the dehumidification load. This continuous overwork accelerates compressor wear and can shorten the life of a system that should last 15 to 20 years.
ENERGY STAR research confirms that sealing and insulating ducts in unconditioned spaces can cut heating and cooling costs by up to 20%. Flex duct degrades over time in South Florida's heat and humidity, and small leaks grow larger as the duct system expands and contracts through daily temperature cycles. Pairing duct repairs with routine air conditioning maintenance keeps your entire system operating at peak efficiency.
If your home has rooms that never reach setpoint, energy bills that do not match your usage, or an AC system that runs constantly without achieving consistent comfort, your duct system is a likely cause. Hopkins Air Conditioning serves West Palm Beach, Boca Raton, Boynton Beach, Jupiter, Lake Worth Beach, Palm Beach Gardens, and communities throughout Palm Beach County.
Common signs include rooms that are significantly warmer or cooler than others, an AC system that runs almost continuously without reaching the thermostat setting, energy bills that seem high for your usage, and visible dust near supply registers. A duct blaster test accurately measures how much air your system is losing.
A duct blaster is a calibrated fan that temporarily pressurizes your duct system while all registers are sealed. The test is completely non-invasive, causes no damage, and takes approximately 30 to 45 minutes. It gives us a leakage number we can compare against Florida Building Code standards.
In most cases, yes. Many duct systems have isolated problems at specific joints or flex duct sections that can be repaired without replacing the entire network. If the system as a whole is too deteriorated to repair effectively, we will tell you honestly and provide options for a full replacement.
