Ductless Mini Split Maintenance in Chicago’s North Shore & Western Suburbs

Protect Your Comfort & Investment with Professional Mini Split Tune-Ups

Your ductless mini split system is one of the most efficient and flexible HVAC solutions on the market. But because it runs all year long heating in the winter and cooling in the summer it requires more attention than traditional HVAC systems. Without routine maintenance, mini splits lose efficiency, develop costly issues, and may even fail years before their time.

At Grand Slam Heating & Cooling, our certified technicians provide thorough, professional ductless mini split maintenance services across Chicago’s North Shore and Western Suburbs. With our tune-ups, you’ll enjoy lower energy bills, fewer repairs, and peace of mind knowing your system is protected.

Heavy Year-Round Use

Unlike furnaces or AC units that get seasonal breaks, mini splits run continuously.

Efficiency Loss

Dirty coils, clogged filters, and neglected components can increase energy use by 20–30%.

Breakdown Prevention

Most emergency repairs we see could have been avoided with seasonal maintenance.

Air Quality Protection

Mini splits filter air at the room level. If not cleaned, they can circulate dust, allergens, and even mold.

Longevity

A well-maintained ductless system lasts 15–20 years, compared to 8–12 years for neglected systems.

Warranty Compliance

Skipping maintenance can void your manufacturer warranty.

Why Ductless Mini Split Maintenance Is Non-Negotiable

What’s Included in a Grand Slam Mini Split Tune-Up

We don’t just “check” your system, we give it a full health inspection and deep clean:

Remove and clean air filters, coils, and blower wheels
Clean and flush condensate drain lines to prevent leaks
Inspect refrigerant levels & pressure; test for leaks
Inspect reversing valve, sensors, and thermostat calibration
Tighten all electrical connections
Lubricate moving parts for smooth operation
Clean outdoor condenser unit
Test system in both heating and cooling modes
Measure airflow to ensure efficiency
Free Indoor Air Quality test included with every visit

Seasonal Timing: When to Schedule Maintenance

Because ductless systems provide both heating and cooling, experts recommend two maintenance visits per year:

Spring

Prepare your system for the high cooling demand of summer.

Fall

Ensure reliable heating performance before winter arrives.

Tip: In between professional tune-ups, homeowners should clean or replace filters monthly (or more often if pets, dust, or allergies are a concern).

Frequently
Asked Question

How long do ductless mini splits last with maintenance?

Most systems last 15–20 years when serviced regularly. Without maintenance, many fail in under 12 years.

Can I clean my mini split myself?

Homeowners should clean filters monthly. However, coil cleaning, refrigerant checks, and electrical inspections should only be done by a professional.

Why does my mini split smell bad?

Musty or moldy odors usually mean the drain line or coils need cleaning something we address during maintenance.

Do you maintain all brands?

Yes. We service Goodman, Amana, Mitsubishi, Daikin, LG, Fujitsu, Carrier, and more.

Do ductless systems need maintenance more often than central HVAC?

Yes, because they run year-round. Twice-yearly professional tune-ups are strongly recommended.
