These are solid homes — but the original HVAC systems have had their day. We see it regularly in Mount Prospect: furnaces running well past their service life, ductwork that was never sealed or balanced properly, and AC units that get limped through another summer instead of replaced. We tell you exactly what's going on and give you a straight answer on what makes sense. When your furnace stops on a cold January night or your AC can't keep up in August, we're already nearby.

"Our 25-year-old furnace finally gave out on a Saturday night. CozyCub came out first thing Sunday morning, diagnosed the issue, and gave us honest options. No pressure, just facts. We replaced it and the new system is whisper-quiet."
— Sarah M., mount prospect

"AC repair on the hottest day of July. Called in the morning, tech was here by 2pm. Turned out to be a capacitor — he had the part on his truck and we were cool again within an hour. Fair price, no upselling."
— Mike R., mount prospect
