Freqently Asked Questions

What should I expect during an HVAC maintenance visit?

Our Chicago HVAC contractors will conduct a thorough inspection and carry out preventative maintenance work. They will also perform detailed HVAC troubleshooting to identify the causes of any existing issues. A maintenance visit is the most cost-effective way to avoid any issues from escalating.

Are HVAC services covered by warranties?

Yes. Many of our Chicago HVAC services are covered by warranties. For our labor work, you can get up to 10 years of warranty. It offers homeowners and business managers peace of mind knowing that they are fully protected against mishaps.

Discuss your HVAC needs with us for the most suitable warranty packages. Extended warranties are available.

How much does your service cost?

Every job is priced individually based on labor, system type, and scope. For example, installing one thermostat will cost less than installing multiple thermostats throughout the property.

And that’s why we promise to always offer a fair, upfront quote first. You will never be blindsided by a surprise bill.

Do you provide same-day HVAC repair in Chicago?

Of course, our Chicago HVAC contractors are always on call and ready to jump in. Contact us via phone or text message to tell us about your emergency. We can send someone out within an hour or up to 24 hours, depending on availability.

How often should I have my HVAC system serviced?

You should always service your system at least once a year. For commercial properties, you may even need bi-annual inspections.

Annual fine-tunings are not only vital in maintaining the system’s efficiency but also in extending the unit’s lifespan. A regularly serviced system will last significantly longer and be in better shape than unserviced units.

Are your HVAC technicians licensed and insured in Chicago?

Definitely. All our specialists are fully licensed and insured to carry out the appropriate HVAC work in the state. Only qualified experts are allowed to conduct most HVAC-related work.

Our certified appliance technicians are experienced and understand the Illinois climate well. They know the issues faced by homeowners and business owners. Every solution is tailored to your needs and budget.
