Modern heat pumps deliver 2-3x more heating and cooling per unit of energy compared to older systems. That means the same comfort at a fraction of the operating cost.

2-3x more efficient

Frequently Asked Questions

Quick answers to the most common questions we hear from homeowners — covering both HVAC and electrical.

For HVAC and electrical emergencies, we aim to be at your door within a few hours, any time of day or night. For standard service calls, we can usually schedule you same-day or next-morning. We always give you a specific arrival window so you are not waiting around all day.

Yes. We provide free, no-obligation estimates for all new HVAC installations, panel upgrades, EV charger installs, and generator projects. For repairs and diagnostics, we give you the price upfront before any work begins so you can make an informed decision.

We service, repair, and maintain every major HVAC brand including Carrier, Lennox, Trane, Rheem, Bryant, Goodman, Daikin, Mitsubishi, and more. For new installations, we help you select the right brand and model for your home, budget, and efficiency goals.

Absolutely. We are fully licensed for residential electrical work in Washington State. All electrical projects are performed by licensed electricians, pulled with proper permits, and inspected to meet current code. We carry full liability and workers’ comp insurance.

Yes — we install Level 2 chargers for all EV makes including Tesla, Ford, Rivian, Hyundai, BMW, and more. We run a dedicated 240V circuit from your panel, mount the charger in your garage or on an exterior wall, and handle the permit. If your panel needs an upgrade to support the charger, we handle that too.

If your home is more than 20 years old, has an older panel, or you have noticed flickering lights, warm outlets, or frequently tripped breakers, an inspection is a smart move. We check your panel, wiring, outlets, grounding, and smoke detectors — and most inspections uncover issues homeowners never knew existed.

We recommend twice-yearly maintenance: once in spring for your AC and once in fall for your heating system. Regular tune-ups extend equipment life, improve efficiency, and catch small problems before they turn into expensive emergency repairs.

Yes. We offer flexible financing options with affordable monthly payments for larger projects like HVAC installations, panel upgrades, and generator installs. Ask us about approval during your free estimate — the application is quick and the terms are straightforward.
