The Best in Air Duct Sealing
Air ducts are often hidden in hard-to-reach areas, making it easy to overlook leaks that allow cool air (and your money!) to escape. Filterbuy HVAC Solutions use proprietary Aeroseal technology to seal these gaps to ensure your system runs efficiently and leak-free.
Using a non-toxic, industry-leading sealant, we seal ducts from the inside to prevent energy loss. Just like a leaky faucet, unsealed ducts can waste hundreds or even thousands of dollars over time. If you suspect leaks, don’t wait—sealing your ducts could cut your energy bill by up to 50%.

AC Installation
When it comes to your comfort and energy bills, cooling systems have the biggest impact. We are experts in matching high-efficiency, reliable, and affordable AC solutions to your home, region, and preferences. That’s what makes us Filterbuy HVAC Solutions.

AC Repairs
Air Conditioners only break down when you need them, which is why we respond quickly so you can be cool and comfortable in your home. Depend on Filterbuy HVAC Solutions for an honest assessment of your repair job.

Yearly AC Tune-Up
Give your AC equipment the check-up it deserves! Regular maintenance will help ensure small issues don’t become big ones.

HVAC Care Plan
Our premium maintenance contract makes sure that all components of your HVAC system receive preventative maintenance on schedule to avoid wallet-busting problems.

Duct Repairs
If your duct’s structural integrity has been compromised (dislodged, punctured, crushed) it will need to be repaired, replaced, and resealed.

Duct Cleaning
Duct cleaning removes years of dust and debris to improve indoor air quality and address allergic reactions.

Duct Sealant
A non-toxic, water-based formula that seals all holes in your air ducts, so cool air is not wasted.

UV Light Installation
Create the healthiest indoor air quality by installing Filterbuy’s Germicidal UV Light. Kill microscopic pollutants, bacteria, and odor 24 hours a day.

Ionizer
Ionizers are a new technology that targets pollutants down to .01 microns in size. Think virus, mold spore, VOCs and more.

Attic Insulation
Low levels of attic insulation will make your AC unit work harder to keep your rooms cool, because heat will transfer through your ceiling. Maximize the energy efficiency of your home with proper attic insulation for south Florida.

Dryer Vent Cleaning
Cleaning dryer vents requires experience and the right tools. Once on site, your Filterbuy HVAC Solutions specialist will inspect the severity of lint build up. Our powerful vacuum & brush technique will guarantee the removal of hard to reach compacted lint.

Signs Your Air Ducts Need Sealing
Leaky air ducts can reduce your home’s comfort, drive up energy costs, and overwork your HVAC system. If you notice excess dust even with clean filters, it could mean air is escaping through gaps in your ductwork.
One of the most expensive consequences of leaky ducts is higher energy bills. When cooled air escapes into your attic or other unconditioned spaces, your HVAC system works harder to compensate, wasting energy and increasing costs. Sealing your ducts helps restore efficiency, reduce expenses, and improve overall indoor comfort.
Common Signs of Leaky Ducts:
- Excess Dust Buildup
- Dusty Vents & Registers
- Visible Insulation in Vents
- Uneven Room Temperatures
- Weak Airflow from Vents
- Rising Energy Bills
- A/C Running Constantly
- Inconsistent Indoor Comfort
