Why Houston Homes Need Regular Duct Cleaning
Houston's subtropical climate creates unique challenges for indoor air quality. With humidity levels regularly above 70%, your air conditioning runs almost year round. That constant airflow pushes dust, pet dander, pollen, and moisture through your duct system. Over time, this buildup can affect how well your HVAC system works and the air quality inside your home.
The Gulf Coast environment also means higher risk for mold growth inside ductwork. Condensation from the temperature difference between cold ducts and warm, humid air creates conditions where mold can take hold. This is especially common in older homes or systems that have not been maintained regularly.
What a Proper Duct Cleaning Includes
A thorough air duct cleaning in Houston should cover your entire HVAC system, not just the visible vents. Here is what to expect from a reputable company:
- Inspection of all supply and return air ducts using a camera or mirror
- Cleaning of each vent register and grille
- Brushing and vacuuming of all main trunk lines
- Cleaning the air handler, blower motor, and evaporator coil area
- Checking for leaks, disconnected ducts, or damage
- Optional sanitizing treatment to kill bacteria and mold spores
The entire process takes 3 to 5 hours for a typical Houston home. Companies that claim they can clean your entire system in under an hour are likely only cleaning the vent covers and not the actual ductwork behind them.
How to Avoid Air Duct Cleaning Scams
Houston has its share of duct cleaning scams. The most common one is the "$99 whole house special" advertised through door hangers or online ads. These companies typically show up, clean a few vents with a shop vacuum, then try to upsell you on mold remediation or other expensive add ons.
Here is how to protect yourself:
- Ask for their Texas HVAC license (TACLA number) and verify it online
- Request proof of liability insurance
- Get a written estimate before any work begins
- Ask what equipment they use (negative air machines and rotary brushes are standard)
- Check reviews on Google and the Better Business Bureau
- Be skeptical of prices that seem too low. Legitimate cleaning costs $300 or more for most homes
