What exactly is included in your written quote for this hvac project?
Ask the company to spell out equipment sizing, efficiency, ductwork or air sealing, controls, permits and removal of old equipment. Get the same level of detail from each company so you can compare the full scope, not just the bottom-line price.
- 02
What license, insurance and relevant experience can you show me?
Ask which Tennessee or local licenses apply to your project in Gallatin, request current proof of insurance, and ask for recent installations in homes similar in size and construction. Verify important credentials with the issuing authority before work begins.
- 03
