Common questions we hear from Chicago homeowners. Don't see yours? Get in touch — we'll answer personally.
Contact UsWe recommend a professional tune-up at least once a year, ideally in the spring before peak cooling season. Annual maintenance extends the life of your unit, improves energy efficiency, and catches small issues before they become costly repairs.
Most residential AC installations are completed in a single day — typically four to eight hours depending on system type and complexity. Larger homes, full HVAC changeouts, or ductwork upgrades may require an extra day.
If your system is under 10 years old and the repair is minor, repair is usually the most cost-effective choice. If the unit is older than 12 years, uses outdated refrigerant, or the repair cost exceeds half the price of a new system, replacement typically delivers better long-term value.
