The Resolution Series

Winterize
Your Comfort.

As we step into the New Year of 2026, many of us are setting goals to be more organized, eco-friendly, and budget-conscious. There is no better place to start than your home’s comfort system.

While your ductless mini split is engineered for high-performance heating, a little "New Year’s resolution" maintenance ensures your OLMO HVAC unit delivers maximum warmth without the soaring utility costs.

Performing regular maintenance is crucial not just for performance, but also for protecting your valuable warranty. Whether you are running a compact Single-Zone unit or a heavy-duty Penta-Zone system, follow these five simple steps to winterize your setup.

01

Clean Filters

Make "clean filters" your first habit of the year. Clogged filters are the leading cause of poor efficiency and high bills.

Action: Open the indoor air handler, wash filters with warm water. This applies to all models, from Monoblock to Multi-Zone configurations.

02

Deep Clean

If you’ve noticed a musty odor or visible dust buildup, it’s time for a deep clean. A DIY mini split cleaning kit allows you to flush out debris that limits airflow.

Vital for maintaining precision engineering in Dual-Zone and Tri-Zone systems.

03

3. Outdoor Condenser Inspection

The outdoor unit is the workhorse of your heat pump system. As winter storms roll in, leaves, dirt, and ice can accumulate around the base.

Protocol

Maintain two feet of clearance. Check for ice around fan guards.

Systems

Essential for TTW (Through-The-Wall) systems.

04

Drain & Insulation

Check exterior line set insulation for cracks. Verify the drain line is clear and not at risk of freezing. Browse Accessories for protective gear for Quad-Zone setups.

05

Heat Mode Test

Start-Up Test: Run for 20 minutes in heat mode. Confirm thermostat cycling. Essential for everything from PTAC units to whole-home heating.
