What Homeowners Often Ask Us About Fixing Their Mini Split Systems

Why choose SumZero for mini split repairs?
We’re mini split experts serving Massachusetts homeowners with fast, honest, and dependable service. Our team is fully licensed and highly rated.
Are replacement parts for mini splits easy to get?
Yes. We have access to OEM parts for most major brands and can source what’s needed quickly if not already on our service vehicle.
How long does a typical mini split repair take?
Most repairs take between 45 minutes to 1.5 hours depending on the issue. We'll always provide an estimate before we begin.
Do mini splits need regular maintenance to avoid repairs?
Yes. Regular filter cleaning and professional maintenance help prevent breakdowns and keep your system running efficiently year-round.
Is it normal for my mini split to run continuously?
Mini splits often run longer than traditional systems for efficiency, but if it never shuts off or struggles to maintain temperature, it likely needs repair.
Why is my mini split leaking water or ice forming on it?
Leaks or ice buildup can be caused by clogged drain lines, low refrigerant, dirty filters, or sensor issues—all of which we can address.

In most cases, yes. We carry a range of parts and tools, and we aim to fix most common problems during the initial visit.
What’s included in your mini split diagnostic visit?
Our $99 diagnostic includes inspection of indoor and outdoor units, electrical components, refrigerant levels, sensors, and communication wiring.
Do you repair ductless mini split systems from all brands?
Yes. We service and repair all major mini split brands, including Mitsubishi, Fujitsu, Daikin, LG, and more.
