Tips for Hiring Air Duct Cleaning Services for your Commercial, Industrial, Municipal and Residential Properties

Reputable, reliable air duct cleaning services will provide a thorough, end-to-end HVAC system inspection and cleaning for a reasonable cost. Unfortunately, there are a number of unscrupulous operators that will start with a low-price “whole house” offer, only to return with hundreds of dollars in additional charges for “discovered” problems. Or worse, these scammers will make a cursory pass on some vents with a vacuum and go (“Blow and Go guys”) – leaving you and your dirty HVAC behind.

To make sure you’re dealing with a reputable air duct cleaning contractor, ask these questions:

How many technicians are coming, and how long do you expect the job to take?

An average size home (2000-3000 square feet) would typically take two technicians the better part of a day to clean thoroughly. It’s not just air ducts: Every component should be included – air handling units, coils, filters, heat exchangers, VAV boxes and more. One person and a couple of hours just won’t do. Ask the contractor exactly what are they cleaning.

Are you certified members of the National Air Duct Cleaners Association (NADCA)?

This organization maintains industry standards and guidelines for proper air duct cleaning and decontamination for consumers and contractors. Its members follow a strict code of ethics and must carry liability insurance. Member companies must also meet NADCA training and certification requirements, and follow the NADCA best practices for HVAC system and air duct cleaning.
