RESIDENTIAL CONSUMER CHECKLIST – GET THE JOB DONE RIGHT!
Our goal at NIAGARA DUCT CLEANING / AEROSEAL is to earn your business. However, we do recognize you may want to shop around to compare services and prices. NDC offer you this checklist to aid in the process. The checklist is designed to help residential consumers understand NDC’s recommendations regarding the process of HVAC cleaning. Residential consumers are advised to read and understand the information on this page before hiring an HVAC cleaning company. To keep the review process organized, place a check next to each discussion topic the contractor has addressed to your satisfaction.
QUESTIONS FOR REVIEW:
- Is the contractor willing to conduct a thorough inspection of the HVAC system PRIOR to performing any work? Does the contractor agree to disclose any problems discovered during the HVAC inspection? (This is required by NADCA’s ACR Standard.)
- Is the HVAC System fully operational (before cleaning)?
- Will/did the contractor clean the supply ductwork?
- Will/did the contractor clean the return air ductwork?
- For metal ductwork: Are the interior ductwork surfaces free of visible debris? Select several sites at random in both the return and supply sides of the system.
- For fiberglass/ fiber-lined ductwork or ductboard: is all fiberglass or lining material in good condition (no tears or abrasions, and is it also well adhered to the interior of the duct?)
