Indoor Air Quality
San Antonio, TX

Breathe Better in Your San Antonio Home

The EPA estimates indoor air is 2–5x more polluted than outdoor air. In San Antonio, that problem is compounded by high summer humidity, cedar pollen season, and homes that run AC almost year-round — continuously recirculating the same air.

Good Times HVAC tests your indoor air quality first. Then we recommend the right combination of solutions for your specific home — no upselling, no products you don't need.

San Antonio Air Quality Issues — What We Deal With Here

San Antonio has specific air quality challenges that most of the country doesn't face to the same degree:

• Cedar fever (December–February) — Mountain cedar pollen season in Central Texas is one of the worst in the United States. San Antonio sits directly in the cedar corridor. During peak cedar season, pollen counts can reach 20,000+ grains per cubic meter. Allergy and asthma sufferers know this as the worst 6–8 weeks of the year. An indoor air purification system with HEPA-grade filtration dramatically reduces indoor cedar pollen concentration.
• Summer humidity — San Antonio summers regularly push outdoor humidity to 70–90%. Without proper dehumidification, indoor humidity can exceed 60%, which promotes mold growth and creates an uncomfortable, clammy environment even at 72°F.
• Dust and caliche — South Texas soil and construction dust enter through HVAC systems and circulate continuously. Standard 1-inch filters barely capture this particulate.
• Mold risk — The combination of heat, humidity, and poorly sealed homes creates conditions for mold growth in air handlers, coils, and ductwork. UV systems kill mold at the source.
• Pet dander and odors — San Antonio's pet-friendly culture means many homes deal with elevated dander, odors, and hair circulating through ductwork.
• VOCs and chemical off-gassing — New construction in San Antonio's booming housing market means many homeowners live in newly built homes with elevated VOC levels from paint, adhesives, and building materials.

IAQ Solutions We Install

• UV Air Purifiers — Kill mold, bacteria, and viruses at the coil and in the air stream. Installed directly in your air handler for maximum effectiveness. Consumer units placed in vents are far less effective than professionally installed coil-mounted systems. Cost: $400–$800 installed.
• Media Air Filtration — 4–5" media filters trap particles that 1" filters miss, without restricting airflow. MERV 11–16 rating. Effective against cedar pollen, dust, and pet dander. Cost: $300–$600 installed.
• Whole-Home Dehumidifiers — Maintain 45–55% RH to prevent mold growth and improve comfort during San Antonio's humid summers. Stand-alone dehumidifiers drain continuously and don't require you to empty a bucket. Cost: $1,500–$2,500 installed.
• Electronic Air Cleaners — Electrostatic filtration for fine particulates, dander, and smoke. More effective than standard filters for submicron particles. Cost: $600–$1,200 installed.
• Energy Recovery Ventilators (ERV) — Bring in fresh outdoor air without losing conditioned air. Replaces stale recirculated air with fresh filtered air. Critical for tight, well-insulated homes where indoor CO2 and VOC levels build up. Cost: $1,200–$2,500 installed.
• Air Quality Monitors — Real-time CO2, VOC, particulate, and humidity readings. Know what's in your air. Cost: $150–$400 installed.

• Homes with pets — Dander, odors, and hair in ductwork; media filtration + UV addresses all three
• Tight, well-insulated homes — New construction in Schertz, Stone Oak, and Boerne growth areas often have low natural ventilation; ERV systems bring in fresh air properly
• Homes with musty smells, visible mold, or condensation issues — UV + dehumidification combination addresses root cause
• Families with young children or elderly residents — Immune-compromised individuals benefit most from cleaner, properly humidified air
