Frequently Asked Questions
How fast can you respond to a heating emergency?
Our emergency team targets a 60-minute response time across Chicagoland, 24/7 including weekends and holidays.
Is my furnace safe to run if it's making strange noises?
Banging, screeching or rumbling sounds can indicate serious problems. We recommend shutting the unit off and calling us before running it further to avoid damage or safety hazards.
How do I know if I need a repair or a replacement?
If your furnace is over 15 years old and repair costs exceed 50% of replacement cost, replacement is usually more economical. Our technicians give honest, unbiased recommendations.
