Experienced HVAC Services in Romeoville, IL 60446 - United Heating and Air Conditioning

In our climate, a frozen AC unit is often caused by restricted airflow or low refrigerant levels. Restricted airflow can be due to a dirty air filter, blocked vents, or failing blower motor. We start by diagnosing the root cause, then perform the necessary repair—whether it's a thorough system cleaning, sealing duct leaks, or safely recharging refrigerant—to restore efficient operation and prevent future freeze-ups.

We offer several solutions tailored to local needs. For Romeoville homes, we often recommend installing high-efficiency air filters, UV light systems to neutralize mold and bacteria common in our humid air, and whole-home dehumidifiers. A professional duct cleaning or sealing service from our team can also significantly reduce dust, pollen, and allergens circulating in your system.

We recommend bi-annual maintenance—once in spring for your cooling system and once in fall for heating. Our tune-up includes checking refrigerant levels, cleaning coils, inspecting electrical components, and ensuring proper airflow. This proactive service is crucial here to catch minor issues before they lead to major failures like frozen coils in summer or no heat on a cold winter night.
