We recommend professional service twice per year: once in early spring for your air conditioning system, and once in early autumn for your furnace or heat pump. Regular maintenance prevents up to 95% of unexpected breakdowns, keeps utility bills low, and maintains active manufacturer equipment warranties.

Our average emergency dispatch response time is under 45 minutes across the greater Chicago metropolitan area. Our emergency service vehicles are on standby 24/7/365 with live GPS tracking and pre-stocked replacement components.

As an industry standard, we follow the "Rule of 5,000": multiply the age of your system in years by the estimated repair cost. If the result exceeds $5,000, or if your system is over 12–15 years old and uses phased-out R-22 refrigerant, replacement is vastly more cost-effective due to higher modern SEER2 energy efficiencies.

Yes. All repair repairs come with a standard 1-year parts and labor guarantee. New full-system installations include a 10-year manufacturer parts warranty and our exclusive 10-year Ventara Workmanship Guarantee.
