Research
Do your research by reading online ratings and reviews from other clients. Reviews can help you find HVAC contractors who have a good reputation for providing value and exceptional customer service.
Referrals and references
Ask your family, friends, and neighbors for referrals. When contacting a contractor for an estimate, ask for references from previous customers. Be sure to contact each reference for information about their experience and whether the job was completed on time and within budget.
Check for certification and license
HVAC certification and licensing will vary from one state to the next. Be sure the contractor you choose has the knowledge and skills required to meet industry standards. Look for these certifications:
- NATE (North American Technician Excellence) – Contractors who hold a NATE certificate have been fully trained and assessed in HVAC systems.

- EPA 608 Certification – Required for contractors who repair and service air conditioners and other HVAC equipment that requires a refrigerant.
Get more than one quote
Talk to at least three different contractors and get detailed quotes that include the cost of all materials and labor and an estimated time to complete the project.
Get a written estimate
An estimate in writing lets you compare quotes and protects you in case of any discrepancies in cost or project scope when the job is done.
