Q&A

How can I tell if my HVAC system was improperly installed in my Collinsville home?

Signs of improper installation include uneven heating or cooling, strange noises like banging or whistling, frequent cycling on and off, and unexpectedly high energy bills. These issues are common and often stem from incorrect sizing, poor ductwork, or faulty electrical connections. Our technicians can perform a comprehensive evaluation to identify and correct any installation flaws, ensuring your system operates safely and efficiently.

Why is cleaning my outdoor AC unit's condenser coils so important in our Illinois climate?

Our humid summers and seasonal debris like pollen, grass clippings, and dust can quickly clog condenser coils. Dirty coils force your AC to work much harder, reducing cooling power, spiking energy costs, and leading to breakdowns. Regular professional cleaning is a key part of maintenance that restores efficiency, prevents costly repairs, and is especially crucial for handling our sticky summer heat.

What routine maintenance does Flow Air recommend to prevent common local HVAC problems?

We recommend bi-annual professional tune-ups—once in spring for your cooling system and once in fall for heating. These visits include cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring proper airflow. This proactive care directly addresses local issues like dirty coils and installation-related wear, maximizing performance, improving indoor air quality, and preventing emergency breakdowns.
