What criteria should I use in selecting an HVAC system cleaner?
|
|
Interview as many local contractors as you can, and ask them to come to your home to perform a system inspection and give you a quotation. To narrow down your pool of potential contractors, use the following pre-qualifications:
- Make sure the company is a member in good standing of the National Duct Cleaners Association (NADCA).
- See if the company has been in business long enough to have adequate experience.
- Enquire whether the company is in good standing with your local Better Business Bureau.
- Get proof that the company is properly licensed and adequately insured.
- Verify that the company is certified by NADCA to perform HVAC system cleaning.
- Make sure the company is going to clean and visually inspect all of the air ducts and related system components.
- Avoid advertisements for "$99 whole house specials" and other sales gimmicks.
- Ask if company has the right equipment to effectively perform cleaning, and if the company has done work in homes similar to yours? Get references from neighbors if possible.
