What do the blinking lights on my mini-split mean?

They're a fault code specific to your brand. We read the code, confirm the cause, and repair it — no guesswork.

One zone works but another doesn't — can you fix that?

Yes. Multi-zone issues are often a communication fault, a failed indoor board, or a refrigerant problem to that head. We isolate and repair the affected zone.

How much does mini-split repair cost in NJ?

Most repairs run $150–$800 depending on the fault. Drain clearing is on the low end; inverter boards are higher. You get an exact price upfront.

Do you install new mini-splits too?

We do — and new ductless heat-pump systems may qualify for NJ rebates up to $16,000. Ask us during your visit.

Are you factory-trained on my brand?

We're trained across Mitsubishi, Daikin, Fujitsu, and all major ductless brands.
