Veteran Air - Saint Louis's Professional HVAC Services

In our humid Saint Louis summers, restricted airflow from a dirty filter or low refrigerant—common in older systems—often causes evaporator coils to freeze. While we can repair the immediate issue, a new, properly sized HVAC installation from Veteran Air addresses the root cause. Our modern, efficient systems are designed for our local climate and include features that maintain optimal airflow and refrigerant levels, preventing freeze-ups and improving your home's overall comfort and energy efficiency.

Absolutely. Smart thermostat issues often stem from incorrect wiring, compatibility problems with your existing HVAC equipment, or firmware glitches. Our Veteran Air technicians are trained to diagnose and repair these connections. We'll ensure your thermostat is properly integrated with your furnace and AC, update its software, and calibrate it for accurate St. Louis temperature readings, restoring the convenient, energy-saving control you expect.

Our comprehensive maintenance plan is your best defense. Our bi-annual tune-ups include cleaning coils to prevent freeze-ups, checking refrigerant levels, inspecting electrical connections to your thermostat, and ensuring all system components communicate properly. This proactive care, tailored for the St. Louis climate, catches small issues before they become major repairs, keeps your smart devices functioning correctly, and extends the life of your entire HVAC system.
