Had ILLIANA out today to fix my thermostat. Technician was very professional and fixed my thermostat and checked out my furnace. Did a great job. This was our second time using ILLIANA and was happy both times. Would definitely use them again.

Kevin P was my HVAC technician. Of all the people I’ve hired, Kevin has easily been the most competent and interested in his craft, which he appears to have mastered. He truly cares about not just doing the job right, but doing the right job. Will definitely be going to Illiana for my future HVAC needs.

We recently had our annual furnace cleaning by Illiana. Our technician was on time and explained everything he did, answered questions and even gave us some helpful tips. Illiana keeps you informed regarding your appointment with reminders and pictures with info on the technician that will be arriving at your home.
