Free Estimate & Written Price Before Any Work Starts
Every estimate from Cardinal Air Duct San Antonio is free, and the price you’re quoted is the price you pay. No per-vent surprises, no truck-roll add-ons, no “we found mold” upsell after we’re already inside. This applies to air duct cleaning, HVAC cleaning, and dryer vent cleaning.

First-Time Customer Courtesy: 10% Off Whole-System Air Duct Cleaning
If you’ve never booked Cardinal Air Duct San Antonio before, take 10% off the written whole-system price. That means your entire duct system, cleaned with our Rotobrush rotary brush system and Nikro HEPA-rated vacuum extraction, at a rate that rewards trying us once. Most standard air duct cleanings in San Antonio run $300 to $500 for a typical single-system home, so this typically puts $30 to $50 back in your pocket.
Valid through March 31, 2027. Mention this offer when you call (254) 347-3897.
Senior & Military Courtesy: $25 Off Any Service
San Antonio is a military city, and Omar Haddad, Owner of Cardinal Air Duct San Antonio, makes sure veterans, active-duty service members, and seniors 65 and older get $25 off any cleaning service we perform. Just mention it when you book, and we’ll apply it to your written quote on the spot.
Valid through March 31, 2027. Mention this offer when you call (254) 347-3897.
Whole-Home Bundle: Ducts, HVAC, and Dryer Vent Together
Book air duct cleaning with a full HVAC unit cleaning and dryer vent cleaning in the same visit, and we’ll build one flat price for all three systems. Because we’re already on site with our Abatement Technologies containment running, the bundled rate typically lands 15% to 20% under booking each separately. In neighborhoods like Stone Oak and Alamo Heights, where two-story homes and long vent runs push system sizes up, bundling is the smartest way to go.
Valid through March 31, 2027. Mention this offer when you call (254) 347-3897.
Seasonal Dryer Vent Cleaning Special: $89 for a Single-Vent Home
For a typical single-family home with a short, direct dryer vent run, Cardinal Air Duct San Antonio cleans the vent from dryer to exterior termination for a flat $89. We see San Antonio homes with lint caked past the halfway point of the run all the time, especially in older spreads around Terrell Heights, and that lint is a fire hazard, not a minor annoyance. If your vent run is longer than 35 feet or has multiple elbows, the price adjusts accordingly, but you’ll know the number in writing before we start.
Valid through March 31, 2027. Mention this offer when you call (254) 347-3897.
How to Redeem
Redeeming a Cardinal Air Duct San Antonio offer takes about two minutes. First, call (254) 347-3897 and mention the offer by name. A live person answers every time, 24/7. Second, book your visit. You’ll get a live arrival window you can track through the Relay Standard, so you’ll know when we’re coming and who’s on the way. Third, when the technician arrives, remind them of the offer. Your written price will already include it, so the number you approved on the phone is the number on your invoice. If anything changes at the door, you don’t pay it.
Every offer above works with our 365-Day Done Right Promise and carries a written guarantee. If the work isn’t right, we come back and make it right within a full year, at no charge. No fine print on that. Call (254) 347-3897 today, mention the offer, and get a price before we touch a single vent.
