ARK Refrigeration & HVAC: Reliable HVAC Services Serving Mokena, IL 60448

This is a common winter issue here. The problem is often a faulty ignition component, a dirty flame sensor, or a gas valve issue. For safety and to prevent further damage, it's best to have a professional diagnose it. Our technicians at ARK can quickly identify the cause, perform the necessary repair, and get your heat running reliably again.

We recommend checking your filter every month, especially during peak heating and cooling seasons. For most Mokena homes, replacing standard 1-inch filters every 1-3 months is ideal. Homes with pets or allergies may need more frequent changes. A clean filter protects your HVAC system, improves efficiency, and maintains healthy indoor air quality.

Our Mokena maintenance visit is thorough and preventative. We clean critical components, check system pressures and electrical connections, test safety controls (including ignition sequences), inspect and clean the flame sensor, and replace your air filter. This proactive service helps prevent winter ignition failures, ensures optimal airflow, and extends the life of your system.
