How to evaluate Certified

Before hiring Certified for general contractor work in Chicago, take a few minutes to verify their qualifications and confirm they are the right fit for your project. The right general contractor for one homeowner may not be the right fit for another, so do the diligence up front.

Verify licensing and insurance

Confirm that Certified carries an active IL contractor license appropriate for the scope of work, plus general liability and workers’ compensation coverage. Ask for the license number and look it up on the state board website. A general contractor that hesitates to share these details is a red flag, regardless of how favorable their reviews look.

Get a written, itemized quote

Request a detailed written estimate that lists materials, labor, permit fees, timeline, and payment schedule. Itemized quotes make it possible to compare Certified side-by-side with other general contractor options in Chicago, and they protect you from scope creep once the work begins.

Ask about project experience

Ask Certified how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a general contractor actually shows up.

Frequently Asked Questions

What kind of services does Certified provide?

Certified is a general contractor that focuses on home services, particularly around air conditioning systems.

How can I tell if my air conditioner needs maintenance before it completely breaks down?

You can check for issues by feeling the air coming out of your supply vents. If the air is warm, the airflow is considerably less than normal, or there is no air at all, it indicates a potential problem.

What should I do if my outdoor AC unit is running but no air is coming through the vents?

If your outdoor unit is running but no air is coming out of the vents, your evaporator coils might be iced over. It's recommended to turn off the unit to allow it to thaw before a technician arrives.

How does Certified determine the best air conditioning solution for a home?

Certified takes into account various factors such as the home's insulation values, sun exposure, current system design, age, and equipment efficiency to determine the most suitable solution.
