AC & Furnace Air Filter Replacement
Start here before anything else. A clogged filter restricts airflow, drops efficiency, and in a furnace, trips the high-limit safety. The right filter matters — too restrictive and you're starving the system, too loose and you're not filtering much. We'll tell you what your system needs and replace it on the spot.
Duct Cleaning
Ductwork in South Texas accumulates dust, allergens, pet dander, and in some older homes, mold. If you're replacing a system or haven't had ducts cleaned in 5–7 years, it's worth doing. We use professional equipment — not a shop vac with a hose attached. Before and after pictures included.
If someone tries to sell you duct cleaning every single year as part of a maintenance plan, that's overselling. Ducts don't get dirty that fast in most homes. Every 5–7 years is the honest answer unless there's a specific reason — renovation debris, a mold issue, a pest problem.
Duct Sealing
The Department of Energy estimates that 20–30% of the air moving through a typical home's duct system is lost through leaks, gaps, and poor connections. In South Texas summer, you're air-conditioning your attic. Duct sealing is one of the highest-ROI improvements you can make to an HVAC system — it reduces energy use, improves comfort in the rooms that were always "too warm," and extends equipment life by reducing run time.
Dehumidifier Installation & Repair
South Texas humidity is not a preference issue. High indoor humidity makes 78 degrees feel like 84, promotes mold growth, and makes allergens worse. A whole-home dehumidifier works with your HVAC system to pull moisture out of the air independent of whether the AC is running. If your house feels clammy in spring and fall when the AC isn't running much — this is the fix.
HVAC UV Light Installation
UV lights installed at the air handler's coil kill bacteria, mold, and viruses that grow on the coil surface and get circulated through the house. Particularly relevant for homes with allergy or asthma concerns. Installation takes about an hour. Bulbs replaced annually — we can do it during your regular tune-up.
Whole House Air Purifier Installation
Standalone HEPA units filter the room they're in. A whole-house purifier installed in the ductwork filters every cubic foot of air that moves through your system. We carry and install several product lines — the right one depends on your system's airflow capacity and what you're trying to filter. Call and tell us what's driving the interest — allergies, pets, wildfire smoke — and we'll match the equipment to the problem.
Heat & Energy Recovery Ventilator Installation
Tight, well-insulated homes have an air quality problem — they don't exchange enough fresh air with the outside. An HRV or ERV brings fresh outdoor air in while recovering heat (or coolth) from the outgoing stale air so you're not losing your conditioning. If you've had a home tightened up with new windows, added insulation, or sealed crawlspaces, ventilation is worth a conversation.
Humidifier Installation & Repair
South Texas leans humid, but forced-air heating in winter drops indoor humidity fast. Very low humidity dries out wood floors and furniture, increases static electricity, and makes the air feel colder than it is. If winter air in your house feels dry, a whole-home humidifier works with the furnace to add controlled moisture. Call for specifics — sizing depends on your home's square footage and construction.
