Three San Antonio IAQ Problems We Fix
-
Hill Country cedar pollen peaks late December through February, and mid to late January is usually the worst stretch. The particles are small, dense, and abundant. A standard 1-inch HVAC filter does not trap them; it clogs faster, airflow drops, the evaporator coil can freeze on a cold-snap morning, and the pollen that gets through circulates room to room. The fix is higher-MERV media filtration plus a whole-home purifier, typically Aprilaire or REME HALO depending on the air handler and the household's sensitivity profile.
-
San Antonio's monsoon stretch runs roughly April through October. Indoor relative humidity above 60% creates mold-growth conditions on cool surfaces: register boots, supply-duct interiors, drain pans, and the back side of drywall on north-facing walls. The standard treatment is a whole-home dehumidifier (Honeywell) tied into the central return, holding the house at 45 to 50% relative humidity. Add a UV light system on the evaporator coil and drain pan if there is any existing mold history.
-
Most San Antonio HVAC equipment lives in the attic, the dirtiest, hottest, most contaminated space in the house. Every leak in the return-air path pulls attic dust, fiberglass, and rodent residue straight into the air handler, then circulates it through the supply ducts into the bedrooms. We see up to 30% conditioned air loss on poorly sealed duct runs, meaning the system works harder to deliver the same comfort.
CLIENT NOTE: One section of this page references a humidity intervention threshold of 55%. The rest of the page and previous pages use 60%. Confirm the correct figure and standardize before publishing.
How the Free IAQ Assessment Works
-
1. Book the free assessment
Call (210) 897-8658 or submit the IAQ assessment form. No charge, no service-call fee, no obligation. We schedule a 45 to 60 minute on-site visit at your convenience.
-
2. On-site assessment
We measure humidity and particulate in multiple rooms, including bedrooms, living areas, and kitchen, because they almost never read the same. We evaluate the current filtration, the ventilation, the duct condition, and the airflow at the registers.
-
3. Written report with three-tier recommendations
Plain-language report on what the readings show, what is causing it, and three-tier fixes: minimum, mid, and comprehensive. We tell you what is worth doing and what would be marginal. The assessment is its own product, no upsell pressure, no manufactured urgency.
-
4. Choose your scope
Once you decide what scope makes sense, we write a line-itemized estimate. Financing is available through Wells Fargo, FTL Finance, and AC Credit Services at 0% for 72 months for qualified applicants.
-
5. Install and performance test
Whole-home purifier or dehumidifier installs typically run 2 to 4 hours. After the installation, we re-measure humidity and particulate, confirm the new equipment is on-spec, and walk you through any controls or filter-change cadence.

Above & Beyond IAQ Approach vs. National HVAC Chains
| Feature | Above & Beyond | National HVAC Chains |
|---|---|---|
| IAQ Diagnostic Approach | Address coil, ductwork, filter, and humidity together, not just one symptom | Often sell single-point fixes (just an air purifier, just duct cleaning) |
| Tommy's IAQ Specialty Since 2019 | Tommy named IAQ his third service specialty because health is more important | Generic upsell, no specialty positioning |
| SA Allergy Season Calibration | Cedar (December through February), oak (March through May), ragweed (August through October), mold (post-monsoon), service timed to allergen calendar | Generic schedule not tied to SA pollen calendar |
| Duct Cleaning Protocol | If the system is clean, the ductwork is clean; we sell maintenance, not standalone duct cleaning | Often upsold standalone duct cleaning when coil cleaning would address root cause |
| Filter Recommendation Tied to Home | MERV 11 to 13 for typical homes; MERV 13 or higher during allergy seasons; honest about HVAC capacity constraints | Highest-MERV filter sold regardless of system capacity |
| Diagnostic Pricing | $89 credited back when you approve the repair | $89 to $149 charged upfront, often not refundable |
| Feature | Above & Beyond | National HVAC Chains |
|---|---|---|
| Whole-Home Solutions vs Single Devices | Layered approach (filter, coil maintenance, UV-C if chronic, dehumidifier if humid) | Single-device push (just buy this air purifier) |
| Honest About Indoor Air Quality Testing | We do not perform formal IAQ testing; we recommend contacting a certified Indoor Environmental Professional if you suspect a serious indoor air issue | Some chains sell IAQ tests that are not accredited |
| No Allergy Clinic Referral Claims | We do not claim referral relationships with allergy clinics | Sometimes claimed in marketing copy |
| 30-Day Callback Warranty | If IAQ symptoms return within 30 days, we re-diagnose at no charge | Often 7 to 14 days, sometimes nothing |
Frequently Asked Questions
Is the IAQ assessment really free?
Yes, $0, no service-call fee, no obligation. 45 to 60 minutes on-site with humidity and particulate measurement, written report with three-tier recommendations. The assessment is its own product. We do not pressure you into an install.
What is the ideal indoor humidity in San Antonio?
40 to 50% relative humidity. Below 40% in winter and the air dries out skin, throats, and wood floors. Above 60% in summer and mold-growth conditions develop on cool surfaces.
Do I need a UV light system?
UV addresses microbial growth, bacteria, and mold on the wet surfaces inside the air handler, typically the evaporator coil and drain pan. UV is most valuable when there is a mold history, when an immunocompromised household member is in the home, or as part of a complete moisture-and-microbial stack with a dehumidifier.
What is an ERV and do I need one?
An Energy Recovery Ventilator provides controlled fresh-air exchange for tight modern homes. It pulls fresh outdoor air in and exhausts stale indoor air, while recovering most of the conditioning energy in the process. Range: $3,000 to $5,000 installed.
