Tulai HVAC | AC Repair & Installation Experts in St. Louis, MO

It depends on the cause and age of your system. Often, a lack of cooling in our humid summers is due to a repairable issue like a refrigerant leak, a dirty condenser coil, or a failing capacitor. Our technicians will perform a thorough diagnosis. If your system is old, inefficient, and requires frequent repairs, a replacement might be the more cost-effective long-term solution. We'll provide clear options so you can make the best decision for your home and budget.

Absolutely. A regular HVAC maintenance plan includes checking and calibrating your thermostat to ensure it's communicating correctly with your system. This can prevent issues like incorrect temperature readings or short cycling, which are common complaints. Our maintenance visits also clean critical components that, if dirty, can cause your system to overwork and trigger thermostat errors, helping you avoid uncomfortable breakdowns during St. Louis's extreme seasons.

For our climate, look for a system with a high SEER rating for energy-efficient cooling and a good HSPF rating for heat pump heating. Proper sizing is critical—a unit too large will short cycle and dehumidify poorly, while one too small will struggle in peak heat. We conduct a detailed load calculation for your specific home to recommend the right capacity, brand, and features, like variable-speed motors, to maximize comfort and efficiency throughout the year.
