Commercial HVAC in Tacoma & Pierce County
VRF / VRV specialists. Full commercial HVAC design, install and service for offices, retail, restaurants, warehouses, multi-tenant and mid-size commercial buildings up to 20,000+ sqft. Call or text 253 370 8641.
GreenFlow Heating & Cooling is a Tacoma-based commercial HVAC contractor with deep VRF and VRV (variable refrigerant flow) experience. VRF is the most efficient way to zone a modern commercial building — simultaneous heating and cooling across zones, quiet operation, tight temperature control and dramatically lower operating cost than legacy rooftop packages. It’s also unforgiving of sloppy design and install. We do it right.
We also handle the full commercial HVAC stack — rooftop units, split systems, ductwork, ventilation, IAQ and everything in between — for property managers, building owners, general contractors and business owners across Pierce County and the South Sound.

VRF / VRV — Our Specialty

Variable refrigerant flow is what we do best. VRF systems use a single outdoor unit connected to multiple indoor units, moving refrigerant on demand to heat some zones while cooling others simultaneously. Done right, they cut commercial HVAC operating costs 30–40% versus older rooftop equipment, run whisper-quiet, and give tenants individual control of their own space.
Our VRF Services
- System design and load calculations for new construction and retrofits
- Full installation — outdoor units, branch controllers, indoor cassettes / concealed / wall / ducted units, refrigerant piping, controls
- Commissioning with documented startup: pressure test, evacuation, refrigerant charge verification, control loop validation
- Service and repair on existing VRF systems (Mitsubishi City Multi, Daikin VRV, LG Multi V, Samsung DVM, Fujitsu Airstage)
- Preventive maintenance contracts sized to the system
- Controls integration — BMS integration, centralized controllers, individual tenant control
Common VRF applications we install: multi-tenant office buildings, medical and dental suites, hotels, restaurants and mixed-use retail. If you’re planning a new commercial build or gutting an existing space, VRF is worth a look — ask us to price it against a conventional RTU replacement.

Commercial HVAC Questions
What makes VRF / VRV worth the investment?
Operating cost. VRF moves only the refrigerant a zone actually needs, and can heat and cool different zones at the same time by recovering heat from cooling zones to warm the heating zones. That typically cuts commercial HVAC operating cost 30–40% versus rooftop packages, plus tenants get individual control and the system runs quietly. Upfront cost is higher, payback is usually 4–7 years.
Do you handle full building HVAC design, or only install?
Both. We design commercial systems from an ACCA Manual N load calc, generate mechanical drawings for permit and install to spec. If you already have a mechanical engineer’s plan we install to that plan and commission it.
What size buildings do you take on?
Up to roughly 20,000+ sqft. Single-tenant offices, retail centers, restaurants, warehouses, medical suites and multi-tenant commercial buildings all fit. Larger campus or true heavy industrial projects are outside our scope — happy to refer.
Can you service existing rooftop units or VRF systems we didn’t install?
Yes. We service every major brand of commercial RTU, split system, VRF and mini-split — including Mitsubishi City Multi, Daikin VRV, LG Multi V, Samsung DVM and Fujitsu Airstage. We diagnose the actual failure, quote before we start and fix it right.
Do you offer preventive maintenance contracts?
Yes — quarterly, bi-annual and annual plans priced per unit. Contracts include documented inspection reports, filter service, coil cleaning, refrigerant charge verification and priority scheduling on emergency calls. Ask about the multi-unit discount.
Do you offer emergency commercial service?
Yes. Call or text 253 370 8641. Contract customers get priority.
Are you licensed and insured for commercial work?
Yes. Fully licensed, bonded and insured in Washington. NATE and EPA Section 608 certified. Certificates of insurance provided on request for property managers and GCs.
