Duct sealing makes sense. There’s a branching network of pipes traveling throughout your house that links heating/cooling equipment to the various rooms. This system carries the conditioned air that keeps you comfortable. It’s the same air you breathe and pay for. When there are holes, cracks, or leaks at the seams, it escapes. That’s very bad news. Carden Heating & Cooling, Inc. provides effective sealing services. That’s very, very good news.

Trusted Duct Sealing Services

Carden Heating & Cooling, Inc. has been handling duct system concerns for 23 years. In our experience, most homeowners are losing up to 30% of conditioned air by neglecting the ductwork. The sealing process isn’t all that expensive, is handled within a few hours, and causes no damage or mess to your home. In other words, our services are definitely worthwhile.

For all your duct sealing needs, call the Carden Heating & Cooling, Inc. team!

We hope you’ll contact us at (205) 669-2459 to have your ducts properly tested. Our NATE-certified technicians offer honest evaluation and recommendations. Resolving problems with the ventilation system increases efficiency, trims running costs, improves comfort, protects air quality, reduces HVAC wear and tear, and optimizes safety. As a family-operated HVAC provider, Carden Heating & Cooling, Inc. takes a special interest in those services that make the biggest difference. We are available for duct sealing across Calera, Alabaster, Pelham, Columbiana, Chelsea, Helena and Hoover, AL.

In addition to a high-quality, fully functioning air conditioning unit, you also need sound ductwork to keep your system running smoothly and keep energy bills low. A leaky duct system can quickly cause indoor air quality to decline, and clogged ducts can cause utility bills to soar. Our experienced technicians have the expertise and industry knowledge to diagnose duct problems and ensure a tailored solution for your family and your home. And while we don’t clean ducts, we do seal, mastic, and replace leaking ductwork. 


Particulates from dirty air ducts do not pose a serious risk to your health, but they can create mild breathing issues, cause unpleasant odors in your home, and contribute to indoor air pollution. Of course, a range of factors contributes to your home’s air quality, including the age of your home, the age of your heat pump or furnace, and many others. 


Many areas of your ductwork are not easily accessible, so you won’t be able to spot-check for leaks or other issues yourself. Also, problematic ductwork could be a signal for a larger underlying problem, so you’ll want an expert service provider to inspect your air duct system for you to determine the best course of action. Loose or leaky ductwork can create negative pressure that actively sucks dust, fiberglass, and dirt into the system.

Even without a more serious underlying issue though, your ductwork will need repair every now and then. Airborne irritants enter your home via leaky ducts and are recirculated when your HVAC system kicks on, which is how your ductwork becomes dirty over time. 

The most effective and thorough option for repairing leaky ducts is to hire a professional who can access hidden and hard-to-reach areas inside your equipment. This will include meticulously checking:

  • Supply and return air ducts
  • Heat exchanger
  • Condensate lines and drain pans
  • Blowers and motors
  • Grills and registers
  • The air handler
  • The evaporator coil

We pressure test ducts with a specialized machine that shows leak rate. From there, we seal and mastic the leaking ducts.


We serve all of Shelby County and Birmingham, AL with all heating, cooling, and air duct needs. Contact our team today to get a quote for our duct cleaning services.

Customer Reviews

Our customers speak for us

Carden is a great company, they have been doing the maintenance on our 2 units and are always very communicative and on time. They also did a duct test, duct repairs and installed a ductless HVAC unit and we couldn’t be happier with their results and the service. I highly recommend them!

Will Eddleman

We have used Carden Heating & Cooling for 20 years. They do regular maintenance on our personal units as well as all our new home installs with our construction company. When my mom’s old dinosaur finally died (after they patched it for years) I called & they came! They were out the next day with a new unit & had her up & running. Their customer service is 2nd to none. From Sara & Amanda in the office to Simon & each of their highly trained technicians, thank you for a job well done!

Janice Seale
