Duct Sealing Tampa, FL

Delivering Comfort, Health, and Peace of Mind To Your Home

Improving your duct system can:

  • Improve Comfort – Sealing and insulating ducts can help with comfort problems than many of us have experienced, such as rooms that are too hot in the summer or too cold in the winter.
  • Enhance Indoor Air Quality – Fumes from common household or garden chemicals, insulation particles, and dust can enter your duct system, exacerbating asthma and allergy problems. Sealing your ducts can help improve your indoor air quality by reducing pollutants entering ducts and circulating throughout your home.
  • Promote Safety – During normal operation, gas appliances such as water heaters and clothes dryers release combustion gases (like carbon monoxide) through their venting systems. Leaky ductwork in your heating and cooling system may cause “backdrafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks can reduce this risk.

Improving your duct system can:

  • Save Money – Leaky ducts can reduce the efficiency of your heating and cooling system by as much as 20 percent. Sealing and insulating your ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you have plans to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.
  • Protect the Environment – Most power plants in the Tampa Bay Area burn fossil fuels to make electricity, releasing greenhouse gases. By sealing ductwork and using less energy at home, you can help reduce these emissions and fight global warming.

How Do I Know if My Duct System is Bad?

Ducts are used to distribute conditioned air throughout your house, but in typical houses, about 20% of the air that moves through the duct system is lost due to leaks, holes, and unsealed joints, resulting in higher utility bills and difficulty in keeping the house comfortable, regardless of the thermostat setting.

Some of the signs that your home may have leaky, poorly insulated, or inefficient ducts are:

  • You have high summer and winter utility bills
  • You have rooms that are difficult to heat and cool
  • You have stuffy rooms that never seem to feel comfortable
  • Your ducts are located in an attic, unfinished basement, crawlspace, or the garage
  • You find tangled or kinked flexible ducts in your system

How Do I Improve the Performance of My Duct System?

Since ducts are usually concealed in walls, ceiling, and attics, repairing them can be difficult. Still, there are things that you can do to improve duct performance in your house. First you can start by sealing air leaks using mastic sealant or metal tape and insulating all the ducts that you can access. Don’t use duct tape, it is not long-lasting. Also, make sure that the connections at vents and registers are well-sealed where they meet the walls and ceiling. These are typical locations to find leaks and detached ductwork.

Your home’s ductwork is one of the most important components of your HVAC system. Because of how important your ducts are, hiring a licensed contractor is the best way to ensure that they work well and consistently. You want a contractor that will, at the very least:

  • Inspect your whole duct system, including the attic, crawlspace and garage.
  • Evaluate your system’s supply and return air balance. Many systems have air return ducts that are too small.
  • Repair damaged and disconnected ducts and straighten out flexible ducts that are tangled or crushed.
  • Seal all leaks and connections with mastic, metal tape, or an aerosol-based sealant.
  • Seal all registers and grills tightly to the ducts.
  • Insulate ducts in unconditioned areas with duct insulation that carries an R-value of 6 or higher.
  • Include a new filter as part of any duct system improvement.
  • Evaluate air flow after repairs are completed.

What Our Customers Say

Phenomenal Service from Alyssa and James!

I had an absolutely amazing experience with The Comfort Authority today! My HVAC technician, Alyssa Lopez, was incredibly thorough during our annual system check-up. I had recently dealt with a backed-up AC drain line, and Alyssa went completely above and beyond to evaluate the entire system. She walked me through every step, checking the outdoor components, electrical wiring, and the indoor system. She even noticed a small leak around my supply plenum and took care of it right then and there—resealing and applying mastic to insulate it better as a total courtesy. To make sure I wouldn't have any more issues, she flushed the drain line out with hot water and added a pan and drain treatment so it flows perfectly. Alyssa is incredibly knowledgeable, friendly, and transparent.
On top of that, James Farley, the plumber, did an equally spectacular job taking care of our home's plumbing systems. He performed a meticulous, top-to-bottom inspection of all our lines, fixtures, and valves to ensure everything is operating at peak performance. He spent extra time performing a full tune-up on our water heater, carefully flushing it out to clear out sediment and keep it running safely and efficiently. Both Alyssa and James are true professionals who took the time to educate me about my home rather than just trying to upsell me. I am so grateful for their hard work, friendliness, and total dedication to quality. I highly recommend them both and will absolutely be calling them back

Always very professional and they take the time to make sure that I understand how the A/C system is working and I understand anything that needs to be done to the air handler or condenser. Rick, Gabrielle, Mike, and James have all been great, and I definitely recommend them.

I'm updating this review in 2026. I've been a client of The Comfort Authority for 9 years now, and they're still as great as they were in the beginning. They schedule appointments quickly, they follow up with you, they're friendly, they explain everything they're doing. If you're looking for someone you can rely on year after year, I highly recommend them.

The Comfort Authority has always sent honest technicians. Glenn and Alyssa were professional and friendly. They both explained the process and physically showed us what was going on with our air conditioning units. They offer products, but aren’t pushy, just informative.

I had a great plumbing inspection and scheduled our tech (I forget his name, but he was awesome) to come out and change out a fitting and pipe to our water heater. He was super punctual, respectful and knowledgeable. I highly recommend comfort authority for AC and plumbing!!

We've been using The Comfort Authority since we moved to Florida 4 years ago and really enjoy working with them. They are honest, fair, and make every effort to help assess what's best for the HVAC unit. Today we had our annual maintenance and our tech Tison was amazing! I really liked his approach, he explained things to me in a way that made sense and was really thorough in servicing our unit.
