Duct Cleaning in Houston, TX

What's included in our duct cleaning visit

Every duct cleaning appointment follows a consistent diagnostic and execution checklist so nothing gets skipped and nothing gets oversold. Here is what a typical visit looks like from arrival to handoff:

• Pre-arrival call. The technician calls 20-30 minutes before arrival, confirms parking and gate codes, and gives you a realistic ETA window — not a vague four-hour block.
• System inspection. Verify thermostat call, check return air filter, listen for abnormal compressor or blower sounds, and look for visible refrigerant leak indicators (oil rings, frost lines, hissing).
• Electrical and refrigerant testing. Measure capacitor microfarads against nameplate, confirm contactor pull-in voltage, check refrigerant subcooling and superheat against manufacturer spec.
• Airflow and static pressure check. Static pressure across the coil tells us whether the duct system is the real problem — restricted returns and crushed flex runs cause symptoms that masquerade as compressor failure.
• Clear written diagnosis. Before any repair, you see the readings, the part recommendation, the labor estimate, and the warranty terms. No upsells, no scare tactics.
• Cleanup and verification. Once the duct cleaning work is complete, the technician runs the system through a full cycle, re-checks pressures, and confirms airflow at every supply register before leaving.

Cost factors for duct cleaning in Houston

Pricing depends on the actual condition of your equipment, not a flat-rate book that ignores reality. Here's what moves the duct cleaning price up or down on a real Houston job:

• Equipment age and brand. Parts for current Lennox, Carrier, Trane, Goodman, and Rheem systems are readily stocked. Parts for legacy or off-brand units may require a special order that adds 24-48 hours.
• Refrigerant type. R-410A is still common; R-22 is phased out and the remaining supply is expensive. R-454B and R-32 retrofits for new installs are growing in 2025-2026.
• Access difficulty. Attic air handlers in 130°F summer attics, rooftop units on commercial buildings, and units behind tight clearance landscaping add labor time.
• Permit and code requirements. City of Houston permits add a fixed fee but protect resale value and insurance claims.
• Time of day. Standard hours run weekdays 7am-6pm. After-hours and weekend emergency rates are higher but available 24/7.

For most homes, common duct cleaning jobs land in the typical $150-$450 range for diagnostic plus minor repairs, with larger component repairs (compressor, coil, blower motor) running higher. Full installs and replacements are quoted separately after an in-home load calculation. We give you a written estimate before any work begins — and we honor it.
