Find the Right Contractor for Your HVAC Project

Whether you’re ready to begin your project now or need some expert advice, our network of contractors are here to help. With a few simple questions, we’ll find the best local professionals for you

  • Request quotes from three to four contractors in your area.
  • Visit the website of each contractor.
    • Is it updated and professional looking?
  • Explore the customer reviews for each contractor.
    • Are they mostly positive? Consider negative reviews and responses.
  • Ask each HVAC contractor on the phone the following questions:
    • How long have you been in business?
    • How much experience do you have with HVAC repair or installation?
    • What is your project estimate?
    • Can you provide a list of references?
    • Can you provide proof of insurance for personal liability, worker’s compensation, and property damage coverage?

Meet With Your Top Contractors

Meet in-person with your top contractors to review project-specific details and expectations. Be sure to discuss the following with each contractor:

  • Ask for proof of insurance, which should provide their insurance company name, policy number, and policy limits.
  • Discuss who will manage warranty details and responsibility.
  • Make sure to get a fixed price before signing a contract.

Be Aware of Warning Signs

Unfortunately, there is a small percentage of contractors who are not honest professionals. The best way to avoid scams is to choose a local, trusted contractor. You can confirm this by checking their physical business address and validating their licensing.

Here are additional warning signs to keep in mind:

  • Avoid hiring a contractor who requests the entire project cost, or large cash deposit, up front.
  • Avoid anyone who pressures you to sign a contract immediately.
  • Be wary of any outliers in your quotes. All estimates should be relatively similar unless the unit type is significantly different.

Prepare for Your Final Contractor Meeting

At the final meeting, there a few steps to go over before the HVAC contractor begins your project:

  • Reconfirm your initial quote.
  • Agree upon a payment plan.
  • Obtain a paper trail of the following:
    • Your contract
    • Project plans
    • Order changes
    • Bills and invoices
    • Proof of insurance and/or permitting, and
    • Contractor correspondence
