FAQs
Do I really need a certified technician to service my air conditioner in Dunlap?
Yes. In Illinois, state and federal regulations require anyone who handles refrigerant to hold an EPA Section 608 certification. Our technicians also maintain NATE and manufacturer-specific credentials, which means your unit is serviced safely, your warranty remains valid, and energy efficiency is preserved. Certified pros can spot developing issues that an unlicensed handyman might miss, saving you money and downtime in the long run.
