OML HVAC - Addison's Reliable HVAC Repair

For reliable performance through our variable Illinois seasons, we recommend scheduling professional HVAC maintenance twice a year—ideally in the spring for your air conditioning and in the fall for your heating system. Our preventative maintenance service checks critical components, cleans vital parts, and ensures your system runs efficiently, which can help prevent unexpected breakdowns and extend its lifespan.

A failed compressor is a common and urgent issue. First, turn off your AC at the thermostat to prevent further damage. Then, contact our Addison team. With 35 years of experience, we can quickly diagnose whether a repair or replacement is the most practical solution. We prioritize these emergency calls to restore your cooling as safely and promptly as possible, and we'll explain all your options clearly.

Our installation process is thorough and collaborative. We start with a detailed assessment of your home's layout and your comfort needs to recommend a properly sized and efficient system. Our experienced technicians then handle the entire installation, ensuring it meets all local codes and manufacturer specifications. We clean up after ourselves and walk you through operating your new system, so you feel confident and informed.
