I'm Leo, the owner of LC Heating & Air. When I visit a home in the Annandale Golf Club area, I often find that the biggest comfort problems aren't caused by the air conditioner or furnace itself, but by the ductwork hidden in the attic or crawl space. If your system is working hard but your rooms still feel uneven, or if your energy bills are higher than they should be, the problem is likely air leaking out of your ducts before it ever reaches your living room.
My approach is practical and honest. I don't believe in selling you a new system if a targeted repair will solve the issue. I'll inspect your ductwork, measure the airflow, and show you exactly where the leaks are. We provide clear, written estimates before we touch anything, and we use testing equipment to prove the repair actually worked.

Common Duct Issues in Annandale Golf Club
The housing stock around Annandale Golf Club includes beautiful historic mansions and large estates, often with complex, multi-zone HVAC systems. These systems face unique challenges. We frequently see crushed flex duct caused by foot traffic in attics, disconnected joints at the plenums, and tape that has simply dried out and failed over time. Because these homes have specific architectural preservation needs, we are extremely careful when accessing ductwork in finished spaces.
Another common pattern here is return air leakage. If your return ducts are leaking in a hot attic, they are pulling in unconditioned, dusty air and pushing it through your system. This not only makes your AC work much harder to cool your home, but it also degrades your indoor air quality by circulating attic dust and insulation fibers throughout your living space.
Why Your Home's Age Matters
Older homes in this area were often built before modern duct sealing standards were common. Over the decades, settling, renovations, and previous repairs can leave a duct system in rough shape. When we work on these properties, we prioritize protecting the historic integrity of the home while ensuring the HVAC system is performing to modern efficiency standards.
We focus on return sizing and register balance. If your ductwork was undersized during a previous remodel, no amount of sealing will fix the airflow restriction. We look at the whole system to ensure that the air is moving where it's supposed to go, which is critical for maintaining consistent temperatures in larger estates.
Our Diagnostic Process
I don't guess when it comes to your home's comfort. We start with a thorough duct diagnostic. This includes measuring airflow at every register to see which rooms are being starved of air. We also perform a duct pressurization test, also known as a duct blaster test. This gives us a number—a percentage of leakage—so we know exactly how bad the problem is before we start.
After the testing, I'll walk you through what I found. If a repair is the right move, I'll explain why. If the ductwork is too far gone or the design is fundamentally flawed, I'll tell you that too. You'll get a written estimate for the work, so you know exactly what you're paying for.
Repair or Replace?
This is the most important conversation I have with homeowners. If your ducts have minor leaks, disconnected joints, or small tears, a repair is usually the best path. We use high-quality mastic and foil tape to seal these leaks permanently. For systems with widespread, inaccessible leaks, we might recommend Aeroseal, which seals the ducts from the inside.
However, if the ductwork is crushed, undersized, or made of outdated materials that are falling apart, a repair is just a band-aid. In those cases, we will discuss the cost-benefit of replacing the affected sections. My goal is to give you a system that works reliably, not one that requires a technician to visit every few months.
Understanding Costs
Duct repair costs vary based on accessibility and the extent of the damage. A simple reconnection of a flex duct in an accessible attic is much less expensive than a full system seal or replacing damaged runs in a tight crawl space. We provide upfront pricing so there are no surprises.
Investing in duct repair often pays for itself through lower energy bills. When you stop losing 20–30% of your conditioned air, your equipment doesn't have to run as long to keep your home comfortable. This also reduces wear and tear on your blower motor and compressor, which helps you avoid more expensive equipment repairs down the road.

Health and Safety
Your duct system is the lungs of your home. If your ducts are leaking in the attic, they are pulling in dust, insulation fibers, and potential mold spores. Sealing these leaks is one of the best ways to improve your indoor air quality. We make sure that all repairs are done correctly so that you aren't pulling air from dirty spaces into your living areas.
We also check for proper airflow balance. If your system is pushing too much air into one room and not enough into another, it can cause pressure imbalances that lead to moisture issues or even backdrafting of gas appliances. We look at the whole picture to keep your home safe and comfortable.
Frequently Asked Questions
Q: How do I know if my ducts are leaking? A: The clearest symptom is rooms that are consistently harder to heat or cool than others, combined with high energy bills. Dusty supply registers can indicate return duct leaks drawing unconditioned attic air. A professional duct pressurization test quantifies exactly how much leakage exists. Q: What is Aeroseal duct sealing? A: Aeroseal is a patented process that seals ductwork from the inside. The system pressurizes the duct network and injects a mist of adhesive polymer particles that stick to and seal leaks as air flows through them. It's particularly effective for leaks in inaccessible sections of ductwork. Q: Can I repair ducts myself? A: Accessible flex duct reconnections are DIY-possible using proper foil tape and mastic. However, most significant duct leakage occurs at joints, plenums, and take-offs in attic spaces that are difficult to access. Improper repairs can make things worse. Q: Will duct repair help my HVAC system last longer? A: Yes. Leaky ducts force your HVAC equipment to run longer cycles. More runtime means more wear on the compressor, blower motor, and heat exchanger. Sealed ducts reduce runtime and extend component life.

“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
