Typical Duct Cleaning costs in Pasadena, TX (2026)
Last updated
Estimated ranges for Pasadena, TX. Actual cost varies with home size, equipment, and scope — always request a written quote for your job.
| Service | Typical range |
|---|---|
| Duct cleaning (whole-home) | $310–$715 |
| Dryer vent cleaning (professional) | $90–$225 |
| Evaporator coil cleaning (in-place) | $135–$400 |
| Duct sealing (Aeroseal or similar) | $1,350–$3,100 |
Avoid the $99 bait-and-switch: NADCA (the National Air Duct Cleaners Association) warns that ultra-low-cost “whole house” duct cleaning ads typically cover only a portion of the system — excluding the air handler, blower, coils, and registers where most contamination sits. A legitimate NADCA-standard clean for an average home runs $450–$1,000 and takes 2–4 hours with a two-person crew. Ask if the quote includes the air handler / blower assembly and request before/after photos.
What Every Pasadena Resident Should Know Before Booking HVAC Services
- Is duct cleaning actually necessary, or is it always upsell?
- Necessary after rodent infestation, post-renovation construction dust, visible mold growth, or 10+ years since last cleaning in a high-pollen or dusty area. Skip "annual cleaning" recommendations — the NADCA 2025 ACR Standard explicitly notes routine annual cleaning isn't evidence-supported.
- How do I avoid the "$99 whole-home duct cleaning" scam shops?
- Ask for NADCA certification, a written scope that itemizes supply + return + main trunk, and confirmation they use source-removal (vacuum-out) rather than blow-and-go fogging. The $99 ads almost always upsell to $800+ on-site for "mold treatment" the home doesn't need.
- Typical HVAC pricing in Pasadena, TX: what should I budget?
- Duct cleaning typically runs $310–$715 in Pasadena, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
