A/C Maintenance
Keep your evaporator coils and drain lines clean with seasonal tune-ups.
Whole-home filtration, germicidal UV lights, and dedicated dehumidification systems designed to eliminate airborne allergens, biological growth, and dust.
The EPA estimates that indoor air can be 2 to 5 times more polluted than outside air. Because modern homes are tightly sealed for energy conservation, microscopic contaminants—such as pet dander, mold spores, volatile organic compounds (VOCs), and dust mites—remain trapped and continuously recirculated throughout your ductwork.
At A1 A/C Service, we treat the root cause of poor indoor air quality. We install hospital-grade media air cleaners (MERV 11–16), germicidal UVC lamp systems over moist evaporator coils to neutralize mold spores, and dedicated whole-home dehumidifiers to keep indoor relative humidity safely below 50% year-round.
If you or your family experience any of these common issues, your HVAC filtration system needs attention.
Caused by mold and mildew colonies propagating on wet evaporator coil surfaces or inside unsealed plenum boxes.
Standard fiberglass 1-inch filters capture less than 15% of particulates, allowing heavy dust to coat duct surfaces and furniture.
Pollen, pet dander, and microscopic dust mite feces recirculating through your ductwork trigger morning congestion.
Warm, clammy air creates an ideal breeding ground for dust mites and toxic mold varieties across drywall and furniture.
High-efficiency MERV 13 to 16 media filtration captures pollen, dust, and animal dander before it enters living areas.
UVC germicidal lamps continuously bathe the evaporator coil in sterilizing light, destroying mold and bacteria DNA on contact.
Dedicated dehumidifiers maintain optimal 45% to 50% relative humidity even when the A/C thermostat isn't calling for cooling.
We test particulate counts, VOC levels, and relative humidity throughout your property's living zones.
We inspect internal duct insulation, plenums, and the evaporator coil chamber for bio-growth or air bypass leaks.
We recommend tailored hardware matching your static pressure limits: media filter cabinets, UVC lights, or dehumidifiers.
Our technicians seamlessly integrate purification hardware directly into your existing supply and return ductwork.
We re-test indoor particulate levels and review filter maintenance intervals with you for lasting fresh air.
Yes. When installed correctly over the evaporator coil and drain pan, germicidal UVC light at a 254-nanometer wavelength destroys the DNA of microorganisms, preventing mold colonies from growing on the moist coil and spreading spores through your ductwork.
If an air conditioner is oversized or its fan speed is calibrated too high, it cools the room temperature quickly but shuts off before completing a long enough dehumidification cycle. An integrated whole-home dehumidifier or variable-speed blower adjustment solves this issue.
