Service Area
Service Area
The full San Antonio metropolitan area — residential and commercial.
We serve residential and commercial customers throughout the San Antonio metro, including all of Bexar County and surrounding communities — neighborhoods inside Loop 410, the 1604 corridor, and outer growth areas like Converse, Schertz, Helotes, and the Pleasanton Road area. If you’re unsure whether we cover your address, call and we’ll confirm immediately.
Yes. We work with restaurants, medical offices, multi-tenant residential buildings, warehouses, and retail properties across San Antonio. Commercial scheduling works around your operating hours — not the other way around.
Service Process
Air Duct & HVAC Service Process
What to know before your first service visit.
For most San Antonio homes, a complete air duct cleaning takes two to four hours. Time depends on the number of supply and return vents in your system — not just square footage. A 2,000-square-foot home with an older layout can have more duct runs than a newer 2,800-square-foot build. We give you an honest time estimate once we know how many vents your system has.
Yes. We use source-removal methodology — debris is extracted from the system, not redistributed into your home. The process creates negative air pressure inside the duct system, pulling loosened material toward a collection device that leaves with our crew. No chemical agents are used in standard duct cleaning, so there’s nothing to air out afterward.
Most customers notice two things: less dust accumulation on surfaces and better airflow from registers that were partially restricted. In San Antonio homes with significant limestone dust or cedar pollen buildup inside the liner, the surface-dust difference is often noticeable within the first week, and airflow improvement is measurable at registers where buildup had partially blocked the opening.
Yes — they’re separate services for completely different systems. Dryer vent cleaning clears the exhaust path from your dryer to the exterior of your home; air duct cleaning addresses the HVAC supply and return system that conditions your indoor air. We perform both, but they’re scoped, priced, and executed independently.
Intervals & Maintenance
Service Intervals and Maintenance
Intervals depend on your home, your household, and San Antonio’s climate.
NADCA recommends air duct cleaning every three to five years under normal conditions. In San Antonio, “normal” means a system running eight to ten months a year through limestone dust, cedar pollen season, and high humidity. Households with pets, allergy sufferers, or recent renovation work often benefit from cleaning closer to the three-year end of that range.
The clearest sign is drying time. If a normal load takes more than one cycle to dry fully, or the dryer runs hot to the touch, the vent line is worth inspecting. Other indicators: a burning smell during operation or visible lint around the exterior cap. Dryer vent cleaning is recommended at least once a year for households running multiple loads a week — more often for larger families or older, longer vent runs.
San Antonio’s mountain cedar season — the December-through-February Ashe juniper event — is one of the most concentrated pollen loads recorded in the country. Filters that normally last 60 to 90 days can load up in 30 or less during a heavy cedar year. We recommend checking your filter monthly during peak season and scheduling a post-season coil inspection if your system ran hard through February.
Insulation, IAQ & Chimney
Insulation, Indoor Air Quality & Chimney Services
Green Air Duct Club covers more than ducts.
It depends on the condition of what’s already there, not just the depth. If existing insulation is dry, undisturbed, and free of pests or moisture damage, blown-in insulation can be added on top to reach the R-38 minimum for our climate zone. If it shows moisture staining, rodent contamination, or significant compression, removal and replacement is the right call. We assess depth and condition before recommending either path.
A germicidal UV lamp installed inside the air handler uses ultraviolet light to inhibit biological growth on the evaporator coil surface. San Antonio’s humidity lets mold and mildew develop on the coil between service cycles; the lamp runs continuously to reduce that growth. It doesn’t replace coil cleaning, but it extends the interval between cleanings and improves air quality between visits.
Both — chimney cleaning and safety inspections are part of our full-service offering across the metro. Annual service matters even for lightly used San Antonio fireplaces: creosote builds with each fire regardless of frequency, and the long off-season leaves caps exposed to UV and wildlife. We inspect the crown, flue liner, mortar joints, and cap on every visit and flag any deterioration before it becomes a water or fire risk.
