Mini split systems are a reliable solution for heating and cooling homes across Newfoundland. With the province’s unpredictable climate, many homeowners run their systems year-round—making routine maintenance a must. However, regular mini split cleaning isn’t just about cleanliness. It’s about efficiency, air quality, and protecting your investment.

At DeepClean NL, we’ve developed a proven and professional approach to mini split cleaning that’s trusted by homeowners across St. John’s, Mount Pearl, Paradise, Conception Bay South, and beyond. Here’s what makes our service stand out and why it matters for your home.

Why Cleaning Your Mini Split Is So Important

Mini split systems are compact and efficient, but they work hard. Over time, dust, mold, pet dander, and moisture can accumulate in key components like:

Air filters

Evaporator coils

Blower wheels

Drain lines

When ignored, this buildup leads to:

Decreased heating and cooling performance

Musty odors and poor indoor air quality

Higher energy bills

Shorter equipment lifespan

Mold and allergen circulation in your living space

DeepClean NL addresses all of these problems with a thorough, technician-led cleaning process.

DeepClean NL’s Expert Mini Split Cleaning Process

Our certified team follows a step-by-step system that ensures every part of your mini split is cleaned and functioning at its best:

1. Initial Inspection

We begin with a full system check to identify performance issues, buildup, or damage. This helps us customize the cleaning process to your system’s specific needs.

2. Filter Cleaning or Replacement

Dirty filters are one of the most common causes of airflow problems. We clean or replace filters to immediately improve system efficiency.

3. Evaporator Coil Cleaning

Dust and biofilm on the coil reduce your unit’s ability to cool or heat. We deep clean this coil using specialized, non-corrosive solutions.

4. Blower & Fan Blade Cleaning

The blower pushes air through your home. If it’s dirty, so is your air. We remove built-up grime from the blower and fan blades to eliminate dust and odors.

5. Drain Line Flush & Pan Cleaning

Standing water can lead to mold and mildew. We flush the drain line and scrub the condensate pan to prevent moisture-related problems.

6. Mold and Odor Treatment

We use eco-friendly disinfectants to eliminate mold spores, bacteria, and unwanted smells—leaving your unit fresh and safe.

7. Final Test & Quality Check

Once everything is cleaned and reassembled, we test your mini split to ensure optimal performance.
