Professional HVAC Maintenance in Glenview & North Shore
Most HVAC companies sell maintenance plans to lock you in. We sell tune-ups because they work — catching small problems before they become emergency repairs, extending equipment life by years, and cutting your energy bills. No contracts required.
80% of heating and cooling failures are preventable with regular maintenance. A $149 tune-up catches the $800 repair before it happens — usually when you need your system most.
Dirty coils, clogged filters, and neglected components make your system work 15-25% harder. Annual maintenance keeps efficiency high and energy costs down — the tune-up often pays for itself.
A well-maintained HVAC system lasts 15-20 years. A neglected one? Maybe 10. That's thousands of dollars difference in replacement costs for a few hours of preventive care each year.
What's Included in a CozyCub Tune-Up
We verify your thermostat reads accurately and responds correctly. A 3-degree error can increase energy costs 10% or more.
Loose connections cause intermittent failures and safety hazards. We tighten terminals and check voltage and amperage on motors.
Dry bearings cause friction, noise, and premature motor failure. Proper lubrication extends motor life and reduces energy consumption.
Dirty evaporator and condenser coils reduce capacity and efficiency dramatically. We clean and inspect for damage or corrosion.
Low refrigerant means your AC works harder while cooling less. We check levels and inspect for leaks that waste money and harm comfort.
We test limit switches, pressure controls, and safety devices that protect your equipment and your family. Peace of mind included.

Twice per year — once in spring before cooling season, and once in fall before heating season. This catches problems early when repair costs are lower and keeps your system running at peak efficiency year-round.
Our tune-ups start at $149 for a single system. We offer $30 off your first tune-up, and discounts when you schedule both heating and cooling maintenance together. No hidden fees — the price we quote is the price you pay.
We show you exactly what we found, explain the issue in plain English, and give you a written quote before any repair work. No pressure tactics, no surprise charges. If it can wait safely, we'll tell you that too — your decision, your timeline.
