    Maddox Comfort Plan

    Air conditioning and heating systems have a knack for failing at the most inopportune times — just when you’re getting ready for visitors or during that first hot or cold weather change.

    That’s why we created the Maddox Comfort Plan. By having your home comfort system regularly inspected by a seasoned Maddox HVAC technician, you can rest assured your home will be comfortable during those extra special occasions, and throughout every season.

    In addition to a comfortable home, by having your air and heating system inspected regularly, you can prevent many surprise expenses, and increase the lifespan of your air-conditioning and heating equipment. Contact us today and let’s discuss a Comfort Plan for your home or commercial building.


    Repair & Replacement

    For over 75 years the Maddox family has been maintaining the air and heating systems in homes, offices, and commercial properties all over East Texas.

    When you call or place a service request on our website, know that we are large enough to address your greatest equipment failure down to the smallest hiccup. Whatever prevents your comfort system from performing, we will get it running at optimum performance. Additionally, with Maddox assured pricing, you’ll know how much the repair will cost before the work begins and be updated during the repair process.

    Remodeling & New Construction

    Are you planning a home remodel or building a new home? In the average home, the air conditioning and heating system is the largest energy usage point. As a part of your project insist on Maddox Air Conditioning for your air and heat design.

    With Maddox professionalism and attention to detail, your new or remodeled home will be equipped with the most efficient and highly functioning air conditioning and heating system, specifically designed for your unique space.

    Preventative Maintenance

    Let’s face it, mechanical devices fail. However, the best response to this reality is preventative maintenance. Maddox Air Conditioning can regularly inspect the various components of your heating and cooling system.

    A seasoned Maddox technician can spot areas of fatigue and potential failure before these issues become catastrophic, thereby saving you money and expanding the lifespan of your HVAC system.
