Your ductwork is the delivery system for every dollar of cooling you pay for. When it leaks, that conditioned air escapes into the attic, crawlspace, and wall cavities long before it reaches your rooms. Research from the University of Florida found that ducts leaking just 20% of conditioned air make your HVAC system work about 50% harder and that typical duct systems lose 25% to 40% of their heating and cooling energy.

In our climate, that’s a double hit. Long, humid Wiregrass summers already push systems to the limit, so a unit fighting duct losses runs longer cycles, wears out faster, and still leaves the house warm and sticky. And here’s the part most homeowners miss: leaky return ducts pull hot, dusty, humid air in from the attic which is exactly why so many of our customers fight constant dust and clammy air no matter how often they change the filter. The AC isn’t broken. The delivery system is.

When Air Command comes out, we don’t just glance at the vents and guess. We trace the airflow from the air handler all the way to the registers — and the leaks tend to hide in the same predictable places:

Here’s why: heat pumps are highly efficient down to around 35-40°F outdoor temperature. Below that, the system’s ability to extract heat from the outside air diminishes. When that happens, the heat strips kick in as supplemental heat to maintain indoor comfort. At 10 kW on 230V single-phase, this kit delivers 34,000 BTU of backup heat — more than enough to keep the home comfortable during system. Dothan’s occasional cold snaps. The built-in circuit breaker eliminates the need for a separate breaker
installation and ensures the system meets electrical code.

Some of these you can spot yourself with a flashlight in the attic. The expensive ones are usually sealed up behind walls or right at the equipment which is where a trained eye pays for itself. (If your system also seems to be running but not cooling, duct loss is often part of the story.)

The photo above is a moment we repeat on nearly every call: opening the air handler. This is where supply and return ducts connect to your equipment, and it’s one of the leakiest spots in the whole system — yet it’s completely out of sight. Loose panels, an unsealed filter slot, and gaps where the cabinet meets the ductwork can bleed off conditioned air and pull attic dust straight into the air you breathe. Sealing this connection is one of the highest-impact fixes we make, and it’s almost never something a homeowner can reach on their own

Once we know where the air is escaping, the fix is straightforward and built to last:

A well-sealed system can cut leakage to a fraction of where it started. Most homeowners notice the difference fast: stronger airflow at the vents, rooms that finally hold an even temperature, less dust, and a power bill that stops climbing.

Duct sealing looks simple on a home-improvement video. In practice, the leaks that cost you the most money are the ones a homeowner can’t see or reach at the air handler, behind walls, and in the connections that take training to spot and the right materials to seal permanently. This is where Air Command’s experience shows.

We’ve been diagnosing Wiregrass duct systems since 2007, and our technicians are trained to trace airflow the way the engineering actually works, not just patch the obvious holes. As an American Standard Customer Care Dealer, we’re factory-trained on the equipment we service, and we’re fully licensed in both Alabama (#07115) and Florida (#CAC1821341). Just as important, we use mastic and code-rated foil tape for seals built to last years not the cloth “duct tape” that dries out and peels in a single Wiregrass summer. Doing it right the first time is what turns a duct repair into lower bills and even comfort for the long haul.

If your power bill keeps climbing, your rooms won’t hold a comfortable temperature, or the dust just won’t quit, the leak is almost certainly in your ducts and waiting only pays the power company more. Let Air Command find it and seal it.
