HOW TO SELECT QUALIFIED SERVICE PROVIDER
1. The company must have an existing physical address in which you are able to confirm its validity. (If the company does not show their mailing address, most likely this is a virtual company in which case you should avoid them at all costs).
2. How long has the contractor been in the HVAC system cleaning business?
3. Can the contractor provide you with evidence of the current Worker’s Compensation and General Liability Insurance coverage? (Ask for Certificate of Insurance.)
4. Does the contractor possess the proper licenses that are required by your city or province to perform the work they are proposing? In Ontario company that work with Gas Appliances have to be registered with TSSA (Technical Standards and Safety Authority) (Our TSSA # 000222226)
5. Will the contractor provide you with 3 to 5 customer references with phone numbers for which they provided service in the last 30 days?
6. (Residential) Will the contractor conducts a thorough inspection of your system PRIOR to performing any work and alerts you to any problems? This is required by the current NADCA Assessment, Cleaning & Restoration of HVAC Systems (ACR) Standard.
(Commercial Only) Does the contractor have written safety, respiratory, and confined space programs in addition to OSHA compliance reports?
7. Will the contractor provide you with a means to conduct a visual inspection at any time during the cleaning? (Mirror and flashlight, camera or other remote visual systems.)
8. (Residential) Will the contractor be cleaning the complete system, including coils and fans? (Use this checklist)
9. Will the contracting company actually do the work? (Some companies subcontract the work to independent contractors. You will want to apply these guidelines for subcontractors as well.)
(Commercial) Will the company be assigning an Air Systems Cleaning Specialist (ASCS) to your project that will be responsible for the complete project?
10. (Residential) Is the contractor giving you a guaranteed price before the inspection? This may expose you to extra costs. Finding mould in the system, damaged fibreglass insulation, cleaning or treating cooling coils may become add-on costs.
(Commercial) If there is any remediation of mould or other biological contamination, does the company have a Ventilation System Mould Remediation (VSMR) on staff?
