Expect More from Your Contractor Some of the biggest and most justifiable fears, when working with contractors, are sub-standard workmanship or that the price quoted is not the final price they will pay. It is quite common for some contractors to secure a job with the lowest bid by using cheaper methods or materials, or end up charging as much as everyone else through additional charges and change orders. That is exactly what gives the industry a bad name. At CIA we guarantee the price we quote and the quality of our work. No Surprise Guarantee! Once the work starts, the price quoted is the price you pay, even if the job entails more work than we had originally estimated. Comfort Guarantee! When you buy from Central Illinois Air, we guarantee that the equipment installed will cool or heat your home to your satisfaction, or we? replace it with something that does.
