Hey everyone, just wanted to chime in about HVAC in Illinois—with a focus on the Lake County area. With the extreme weather fluctuations we get around here, it’s super important to have a solid heating and cooling solution. I recently had work done by a local HVAC company called Optimized Air HVAC eco-friendly options (blog.equisense.com) Air Heating and Cooling in the Round Lake area, and they were awesome—quick response, affordable costs, and walked me through the whole process. If you're facing furnace problems or need an AC tune-up before the warm months, I’d encourage finding a nearby company that understands Illinois weather. Take care!
