Crazy AC Guy, the top HVAC contractor for Sherman and Denison, Texas, is a family business that thinks of our customers like family.

We believe the key to success in the air conditioning business (and any business) is to form solid relationships with customers. One of the ways we do this is to build trust by charging reasonable rates and providing an easy-to-understand bill or estimate for the quality work we do. Since our air conditioning company has been in business for 25 years, we think our ideas have been proven to be good ones.

In North Texas, both heat and air conditioning are important parts of everyday life. When yours isn’t working, you’re uncomfortable. That’s the time to call a reliable HVAC contractor — Crazy AC Guy. We’ll come quickly to find out what’s wrong with your heating or cooling system — even in the middle of the night, because we’re available for emergency calls 24/7.

When you need furnace or central air conditioning installation, it’s important to choose an HVAC contractor you trust that will do the job right. However, when it comes to furnace or AC repairs, it’s experience that counts. Our AC techs have decades of experience, and that helps us diagnose issues and repair them faster than HVAC contractors with fewer years on the job.

Our experience also helps us evaluate whether it’s a better idea for you to get repairs or replacement. We work with new HVAC equipment every day, and we understand the difference newer models make in terms of both convenience and efficiency. We also offer free estimates, so you’ve got nothing to lose.

Whether you need HVAC maintenance, repairs or installation in Sherman or Denison, rely on Crazy AC Guy. Our team is known for our skill, professionalism and dependability.
