Over 1,000 residential installations across Upstate New York.
Ductless mini-splits put a slim indoor unit in each room you want conditioned. One outdoor unit feeds them. Heats in winter (down to -15°F), cools in summer, no ductwork required. Each room sets its own temperature.
Through NYSERDA's Clean Heat program, eligible homeowners can receive rebates on qualifying cold-climate heat pump installations. Amounts vary by utility territory, home size, and whether you decommission existing fossil-fuel systems. We identify exactly what you qualify for in your written proposal.
We perform an ACCA Manual J load calculation before recommending equipment. Oversized mini-splits short-cycle, undersized ones run constantly — both shorten equipment life. We size it right the first time, in writing.
Single-zone mini-split installations start at $5,000 (IGS published entry pricing). Multi-zone systems and whole-home configurations price higher based on Manual J load and zone count. Final price comes from an in-home assessment — written, line-itemized, no surprises.

A local IGS engineer visits your home — typically 45–60 minutes. We check your existing heating system, insulation, room layout, and where mini-split units would mount. You ask any questions. We don't pitch on the visit; the proposal comes after.
Our in-house engineering team sizes the system from a real Manual J load calculation and selects the right equipment mix (single-zone, multi-zone, or hybrid with existing furnace). You receive a written, line-itemized proposal with every rebate and credit you qualify for.
We handle NYSERDA Clean Heat paperwork, utility rebate forms, and town permits. You don't fill anything out.
Single-zone mini-split: 1 day. Multi-zone: 1–2 days. Whole-home or hybrid configurations: 2–4 days. Commissioning and homeowner walkthrough included.
No pressure. No obligation. If a mini-split isn't right for your home, we'll tell you — we've recommended other options when they were the better fit.
Reviews from real IGS customers across Upstate NY.
“We were spending a fortune on heating oil. After our Mitsubishi install, that bill went way down. The house is also more consistently comfortable — no more cold spots like before.”
“I was worried about heat pumps in an Ithaca winter. IGS showed me the cold-climate data and the Manual J calc. Two winters in — we haven't needed the backup heat once. I'm a convert.”
“Ductless was the right call for our older farmhouse — no ductwork needed. Each room has its own control. The crew was professional and finished in two days. We love it.”
What does a mini-split cost?
Single-zone mini-split installations start at $5,000 (IGS entry-level pricing). Multi-zone systems and whole-home configurations price higher based on the Manual J load calculation, zone count, and equipment selection. Financing is available from as low as $49/month for qualified homeowners (EFS Finance — terms vary by credit). Final price comes from an in-home assessment, written and line-itemized.
Do mini-splits work in cold New York winters?
Modern cold-climate mini-splits are rated to heat efficiently at outdoor temperatures down to -15°F. IGS only installs equipment proven in Upstate NY — we've tested these systems through multiple winters with real customer data.
Can I keep my existing furnace as backup?
Yes — a hybrid configuration is common. The mini-split handles most heating loads; the existing furnace provides backup on the coldest days. We'll design what's right for your home, not what's easiest to install.
What rebates are available for mini-splits in New York?
NYSERDA's Clean Heat program provides rebates for qualifying cold-climate installations. The amount depends on your utility territory, home size, whether you're decommissioning fossil-fuel heat, and whether your ZIP is a Disadvantaged Community. We quantify exactly what applies to your project in the written proposal.
How long does installation take?
A single-zone mini-split is typically 1 day. Multi-zone systems run 1–2 days. Whole-home or hybrid configurations 2–4 days. Install time doesn't include permit + rebate paperwork, which adds a few weeks upfront — we handle all of it.
What brands of mini-splits do you install?
Mitsubishi (authorized dealer), Samsung (Preferred Dealer Plus), and Bosch. We match the equipment to your home and goals — we're not tied to one brand.
What's the warranty?
Typical equipment warranties run 10–12 years on compressors and 5–10 years on parts, depending on brand. IGS provides a separate workmanship warranty on the install. All warranties are documented in your written proposal.
A local IGS engineer visits your home, measures the load, and gives you a written proposal with every rebate and credit applied. No pitch on the visit — the proposal comes after.
