GreenFlow Heating & Cooling

GreenFlow Heating & Cooling is a family-owned HVAC contractor operating from Tacoma, Washington, with licenses spanning refrigeration, electrical, and heating (WA LIC GREENHC754B2, ELECTRICAL LIC JOSLINB822PJ, REFRIGERATION LIC 552136076110). Founded by Nathan Joslin, who brings commercial HVAC experience to the residential market, the company holds a perfect 5.0-star rating across 55 verified reviews. Serving the Greater Tacoma area and Pierce County, the team specializes in heat pump systems, ductless mini-splits, furnace replacements, and custom home HVAC design. Every technician is NATE and EPA certified, with background-checked and drug-tested staff handling service calls.

What distinguishes GreenFlow from regional competitors is their commercial-grade craftsmanship applied to residential projects. They are authorized Mitsubishi dealers offering variable-speed heat pumps backed by a lifetime workmanship guarantee on all installations. Their indoor air quality services include HEPA air purifiers, humidifiers, and ventilation systems, while their custom home division collaborates directly with builders and architects to protect build timelines and finishes. The company maintains an in-house team handling every phase from design through commissioning, and offers a 5% community discount to EMTs, firefighters, police officers, and military veterans as a thank-you for public service.

Customer stories reveal why the company earns consistent referrals. When Jesse Kostecka needed a gas line extension and high-efficiency HVAC system, Nathan provided multiple options more affordable than competing bids and passed inspection the first time. David Sosnow, renovating his home in Olympia, found that only Nathan approached his cramped attic challenge creatively, delivering a heat pump, air handler, full ductwork, and HRV system that his inspector called one of the nicest residential installs he had seen. Jesse Barham received two single-zone Mitsubishi minisplits with thorough option walkthroughs, while Oscar Lepe got same-day assessment and afternoon estimation when his furnace failed. Nathan personally oversees every project.
