Central AC Service: Keep Your Home Cool

When the summer heat hits Chicago, IL and surrounding areas, your central air conditioning system becomes your home’s MVP. To ensure your AC unit continues to perform at its best, regular Central AC Service is essential. At Guardian Heating & Cooling Service, we have been proudly serving up comfort all across Chicago, Northbrook, Lincoln Park, Skokie, Glenview, Highland Park, Wilmette, Niles, Morton Grove, Glencoe, and Winnetka, IL since 1953. Our family-oriented business is large enough to service all makes and models of equipment, yet small enough to care. Your comfort is always our #1 priority.

Why Regular Central AC Maintenance Matters

Just like your car, your central air conditioning system requires regular maintenance to function efficiently and reliably. Without proper Central AC Maintenance, your unit may experience:

  • Reduced efficiency: A poorly maintained AC unit has to work harder to cool your home, leading to higher energy bills.
  • Increased breakdowns: Neglecting regular maintenance can lead to more frequent and costly repairs.
  • Shortened lifespan: A well-maintained AC unit can last up to 15 years, while a neglected one may only last half that time.

Our high standard of professionalism will give you peace of mind as you make all your informed decisions about your Central AC Service needs.

What’s Included in a Central AC Tune-Up?

During a Central AC Tune-Up, our skilled technicians will:

  1. Inspect and clean the condenser coils
  2. Check refrigerant levels and recharge if necessary
  3. Lubricate moving parts to reduce friction and wear
  4. Test the thermostat and calibrate if needed
  5. Inspect and tighten electrical connections
  6. Clean or replace the air filter
  7. Check the condensate drain for clogs
  8. Test the system’s overall performance

We always strive to offer a large array of comfort solutions, not just a quote. Rarely is there only one way to achieve the perfect level of comfort. We firmly believe in educating homeowners and allowing them to make an informed decision.
