Proactive care. Priority service. Call 253-370-8641 to enroll.

The GreenFlow Preventative Maintenance Program is built for homeowners who want dependable comfort year-round without the stress. Members get scheduled, thorough inspections — not quick drive-by tune-ups — priority scheduling when something goes wrong, and real savings on repairs.

Every visit is designed to catch problems early, improve efficiency, and extend equipment life. You stop reacting to emergencies and start preventing them.

Why Maintenance Matters

Most HVAC failures trace back to a short list of causes:

Dirty coils
Restricted airflow
Failed electrical connections
Neglected refrigerant issues
Poor condensate drainage

Routine maintenance prevents an estimated 70–80% of emergency breakdowns, protects your manufacturer warranty (most require documented annual service), and keeps efficiency from quietly slipping year over year.

Choose Your Plan

Basic Membership — $350/year

One preventative maintenance visit per year
Comprehensive 29-point Precision Inspection
Full preventative cleaning and performance verification
10% discount on repairs
Priority scheduling
Loyalty credit toward a future system replacement
Documented service history for resale value

15% discount on repairs

Elite is the right plan for anyone running a heat pump or a combined heating and cooling system, since that equipment works year-round and benefits from being checked in both modes.

What the 29-Point Inspection Covers

Combustion analysis and safety controls, heat exchanger inspection, refrigerant charge verification, coil cleaning, blower wheel and motor inspection, capacitor and contactor testing, electrical connection tightening, condensate drain clearing, thermostat calibration, filter replacement, static pressure and temperature-rise measurement, and a written report of what we found.

Membership FAQs

When are the visits scheduled? We reach out to you — heating checks in the fall, cooling checks in the spring. You don’t have to remember it.

Does the plan cover parts and repairs? The membership covers inspection, cleaning, and performance verification. Repairs are billed separately at your member discount (10% Basic, 15% Elite).

Does it cover more than one system? Each membership covers one system. Homes with two systems (or a furnace plus a separate ductless unit) can add a second membership at a reduced rate — just ask.

Is maintenance really required for my warranty? Most manufacturers require documented annual maintenance for the parts warranty to stay valid. The service history we keep satisfies that requirement.

What if my system breaks between visits? You go to the front of the scheduling queue, and Elite members pay no after-hours fee on emergency calls. See our repair page.

Can I use my loyalty credit toward a new system? Yes. Your accumulated credit applies toward a future replacement with us.

Do you maintain equipment you didn’t install? Yes, on most major brands, as long as it’s in serviceable condition. If we find something unsafe on the first visit, we’ll tell you before enrolling you.

> “Nathan was incredibly thorough in helping us choose the right HVAC system for our home… We ended up with a whole-house heat pump that’s been working perfectly.
