HVAC Services McHenry IL | Call Combined Services HVAC

A frozen HVAC component, often caused by clogged air filters or refrigerant issues, is common in our climate. First, turn the system off to prevent damage and allow it to thaw. Check and replace dirty air filters, which are a frequent culprit here. For a thorough diagnosis and repair, call our 24/7 emergency line. With over 20 years of experience, our technicians can quickly identify the root cause—whether it's airflow restriction, a refrigerant leak, or other factors—and get your system running safely and efficiently again.

We recommend scheduling professional HVAC maintenance at least once a year, ideally in the spring for your cooling system and fall for heating. Given the local temperature swings and common issues like clogged filters, this regular check-up helps catch small problems early. Our maintenance service includes cleaning key components, checking refrigerant levels, and ensuring all parts are functioning correctly. This proactive care maximizes system efficiency, prevents unexpected breakdowns, and can extend the life of your equipment, saving you money on energy and repairs.
