Using our years of experience and state-of-the-art technology, we'll get your cooling or heating systems up and running as quick as possible. If it's in the middle of a hot Texas summer or a cold winter's day, we're there for you.
HVAC Systems
The average lifespan of an HVAC system is about ten years. When (not if) it fails beyond repair, we'll provide very competitive prices and quick turnaround times to get your home or office back to a comfortable temperature.
Seasonal Checkups
When you keep your system well maintained, it performs better, costs less to run and extends the lifespan of the components. Don't come home to a hot house in July!

Why Code 3 Air Conditioning and Heat is Allen’s Favorite HVAC Company
Our Installation Staff
Do you want a company that stands behind their reputation and guarantees their work? Some companies employ day laborers, so there is no continuity between the staff and the quality of jobs. At Code 3 Air Conditioning and Heat, we have a dedicated installation staff that have been trained and supervised according to our high standards,
Affordable AC Systems
We don’t skimp on the quality of our job, but that doesn’t mean it’s going to be expensive. At Code 3 Air Conditioning and Heat, we keep our overhead to a minimum and negotiate good deals on the equipment. This means that we can pass the savings on to you. We often beat our competitors’ prices.
While price may be a major factor, so is cost. As the DFW local motivational speaker Zig Ziglar would often explain, “There is a difference in cost and price. Price is what you initially pay for something and cost is the long term investment into that item”.
Is it worth it to save a little bit on price up front by going with a cheaper system installed by cheap labor and risk it breaking down in the heat of the summer with an expired warranty? We think not, and we’re sure you would agree with us.
Are we the cheapest HVAC company in Collin County? No. And we don’t want to be known for the lowest price. We want to be known for installing a system that will meet your needs and serve your family for many summers and winters to come. Hopefully the only time you will see us is when you call us for a seasonal system checkup.
