Frequently Asked Questions

How quickly can you respond to a heating emergency?

We offer same-day and 24/7 emergency service throughout Will County. In most cases, we can have a technician at your home within 2-4 hours.

Do you repair all types of heating systems?

Yes. We repair gas furnaces, oil furnaces, heat pumps, boilers, and electric heating systems of all major brands.

How do I know if I need a repair or a full replacement?

Our technician will give you an honest assessment. If your system is older than 15 years or repairs would cost more than 50% of replacement, we'll recommend replacement and explain why.

What are common signs my heating system needs repair?

Unusual noises, uneven heating, higher energy bills, frequent cycling, yellow pilot light, or a system that won't turn on are all signs you need professional service.
