Adding a mini split to your Redmond home? We install single and multi-zone systems and handle Energy Smart Eastside rebate paperwork.
Common Reasons Redmond Homeowners Install Mini Splits
Single-Zone Mini Split — one indoor head for a single room or addition, the most common Redmond install for home offices and primary bedrooms.
Multi-Zone Mini Split — up to eight indoor heads run from one outdoor unit, suited to larger Redmond homes needing whole-house coverage without ductwork.
Whole-Home Ductless Conversion — replacing electric baseboard heat throughout a Redmond home with a coordinated multi-zone system.
Mini split installation looks straightforward but the details matter — line set length, elevation change, refrigerant charge, indoor head placement for airflow, and outdoor condenser location for both service access and neighbor sound impact. Our Redmond crew walks the house first, listens to how you actually use each room, and lays out a configuration based on that, not a template.
We handle the Redmond city permit, coordinate electrical work if a new circuit is needed, and pressure-test and vacuum the refrigerant lines to manufacturer spec before charging. Skipping the vacuum step is one of the most common shortcuts we see from cheaper installers, and it’s what causes systems to fail early. We don’t cut that corner.
If your install qualifies for Energy Smart Eastside or PSE rebates — most Redmond installs do — we prepare and submit the paperwork on your behalf as part of the job. The workmanship warranty on our labor stacks with the equipment manufacturer’s warranty, so you’re covered on both sides for years after commissioning.
The line set install phase is where a lot of ductless installations quietly fail — improper pressure testing, skipping the vacuum step, or nitrogen brazing done poorly. Our Redmond crew pressure-tests every line set to 500 PSI with nitrogen, holds it for a documented period, then triple-evacuates with a micron gauge before charging. This adds an hour or two to the install and it’s the difference between a system that runs 15 years and one that leaks refrigerant in year three.
For Redmond homeowners considering ductless as an alternative to central AC specifically, one advantage worth mentioning: ductless systems avoid the significant duct losses that older Redmond ductwork typically experiences. Studies consistently show 20-40% of central system output can be lost through leaky or poorly insulated ducts, particularly in attic runs. Ductless delivers heating and cooling directly to each room without that loss, which is part of why the operating cost is often better than the SEER rating alone would suggest.
