Get Your Instant Estimate →Niles's housing stock is quintessential postwar Chicago suburbs: block after block of solid brick ranches and raised ranches from the 1950s and 60s, split-levels and two-stories filling in through the 70s and 80s, and a mix of condos and townhomes throughout. These homes were built to last — but the original forced-air systems weren't. We see it constantly in Niles: furnaces and AC units that are 20-plus years old, ductwork that was never balanced properly, and equipment that's been repaired one too many times. We assess the whole system and give you a straight answer on what actually needs to happen. 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., niles
★★★★★
"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., niles
