When you look for an contractor, you should be asking yourself if they have the experience and training necessary for the project. Without a solid knowledge of HVAC products, experience with unique or difficult installations, or a strong awareness of the HVAC installation requirements, your contractor may not be right for your project.

Here are a few questions you should ask before choosing who to work with:

  • Are you a licensed and bonded contractor?
  • How many years of prior experience do you have as an contractor?
  • What training have you received on installation and repair?
  • How will you ensure the quality of the  installation?
  • What are the latest technologies available?
  • Have you installed or repaired the type of products I am interested in?

It’s important to find a contractor you can trust. Here’s a testimonial from one of our recent projects:

“Had them repair an HVAC unit repaired after it went out during the last heat wave. Service was prompt and professional, had the unit up and running very fast. Will definitely use them in the future.”

Contact our HVAC technicians today! We are happy to answer these questions for you and reassure you of our qualifications.
