Home / Services / Mini-Split Repair
Astello repairs ductless mini-splits and heat pumps across Troy, Albany, Schenectady, and the nearby towns — most makes and models (call and we’ll confirm yours). A lot of what we fix is someone else’s install: bad flares, low refrigerant, a system sized wrong from day one. We find the actual problem, price it up front, and our EPA-certified techs get it right.

Here’s what we see most: a mini-split that “never cooled right” from the day it went in. DIY kits and cut-rate installs make it look easy, but the details are where they fail — a flare joint that wasn’t torqued right and slowly leaks, a line set run longer than the manufacturer allows without adding refrigerant to match, a unit two sizes wrong for the room. The system limps along, draws more power, and eventually quits. We diagnose all of it — refrigerant, electrical, sensors, controls — and we’ll tell you straight whether it’s worth repairing or you’re better off replacing.

From the field
“Looks easy to install” is the most expensive four words in this trade. Most of our repair calls come down to install mistakes the homeowner never sees — until the system quits in the middle of July or January.
A blinking error light tells you something's wrong, not what. We work the system end to end — pressures, charge, connections, sizing — so the fix holds instead of coming back in three weeks.
A big share of our repair calls are DIY jobs and cut-rate installs gone wrong. We’ve seen the failure patterns enough to spot them fast — and fix them for good, not just clear the error code.
We service ductless systems well beyond the brands we install — Mitsubishi, Senville, Cooper & Hunter, and more. A few have proprietary parts, so it’s best to call and confirm we cover yours before you book.
You get the price before any work starts, from EPA-certified techs. If a repair doesn’t make sense on an old or badly-installed system, we’ll say so instead of chasing the bill.
Tell us what’s going on and we’ll schedule a diagnostic visit that works for your schedule.
We pinpoint the actual fault — leak, charge, electrical, or a bad install — and explain your options with up-front pricing.
We fix it right — refrigerant, electrical, sensors, or parts — usually on the same visit.
We test the system, make sure it’s running efficiently, and help you keep it that way.
Mitsubishi Authorized Dealer
Cooper & Hunter Gold Dealer
Senville Pro ContractorMost of them. We regularly service Mitsubishi, Senville, Cooper & Hunter, and plenty of other ductless brands — not just what we install. A few systems use proprietary parts or tools, so it’s always best to call with your brand and model and we’ll confirm we can cover it before you book.
Yes — that’s a big part of what we do. DIY kit or another contractor, we diagnose it fresh: check the flares and connections, verify the refrigerant charge against the line-set length, confirm it was sized right, and go from there. Sometimes it’s a quick fix; sometimes the install was the problem, and we’ll tell you what it’ll take to make it right.
We schedule diagnostic visits as quickly as possible and aim to fix most issues in a single visit.
We give you clear, up-front pricing after diagnosing the problem — no surprises. Financing is available for larger jobs.
Yes — on demand, no membership required. A maintenance visit covers coils, filters, drains, electrical, and a leak-detector sweep, and the visit fee goes toward any work your unit needs. It’s how you catch the small stuff before it becomes a repair call.
If your unit is over 15 years old or needs frequent repairs, we’ll honestly walk you through whether a repair or a new, more efficient system makes more sense.
Yes — our technicians are EPA-certified and fully insured.
