Ductless Mini-Split Installation & Replacement
Get My Quote
Yes, a ductless mini-split can fix uneven temperatures, one room at a time, from a single remote or your phone. No more hauling window units, fighting over one thermostat, or living with rooms that never catch up. KO HVAC installs and replaces ductless mini-splits across the Kingston area, so heating and cooling finally work around you.
Each indoor unit heats and cools its own space, which suits Kingston's older homes and newer builds alike. It connects outside through one small opening in the wall. That means no new ductwork, no torn-up ceilings, and an install that's often done in a day.

Some homes need a first mini-split, and others need a fresh one to replace a tired system. Either way, the signs tend to show up in the rooms you use most. Here's what points toward an installation or a replacement.
Every June, the window units go back in, block the view, and hum through the night. They cool one spot while the rest of the room stays warm. A wall-mounted head cools quietly and keeps the window clear.
The addition, sunroom, or finished attic runs hottest in summer and coldest in winter. Your central unit simply can't push enough air that far. A single indoor head gives that room a thermostat of its very own.
Coal-era homes on the West Side often heat with radiators and were never built for ductwork. Adding ducts means opening walls and giving up closet space. A mini-split brings in cooling, plus a second source of heat, through one small opening.
Electric baseboard and aging oil systems can make January bills painful to open. A mini-split moves heat instead of making it, so it uses far less energy for the same warmth. Adding one can ease how hard the old system has to work.
Your ductless system has seen a lot of seasons, and the repair calls keep stacking up. Older units also lose efficiency and struggle on the hottest and coldest days. When the fixes cost more than they save, a replacement starts to pay off.
Older heat pumps often lose steam when temperatures drop into the teens. You end up leaning on space heaters or a backup system every cold snap. Today's cold-climate models are built to keep heating through a Pennsylvania January.

Most single-zone mini-split installations run about $4,000 to $7,000. Multi-zone systems, with heads in several rooms, often land between $10,000 and $25,000. The number of heads, line length, electrical work, and head style decide where your home falls.
KO HVAC visits your home and gives you a written estimate, broken down so you can see each zone's share. Nothing gets installed until you approve that quote. New installs can qualify for 0% financing for 36 months, with approved credit.

There's more than one way to go ductless, and the best fit depends on your floor plan. One head handles a single problem room, while several heads or a hidden ducted unit can carry a whole house. We'll only suggest what your home needs.
| Single-zone | Multi-zone | Ducted mini-split | |
|---|---|---|---|
| Best for | One room, an addition, or a sunroom | Several rooms on one outdoor unit | Whole floors, with no units on the walls |
| Indoor equipment | One wall-mounted head | A head in each zone | A hidden air handler with short duct runs |
| What you see | One unit on one wall | A unit in each room | Only the vents |
| Temperature control | One setting | A separate setting in every room | Zoned by area, depending on the design |
| Good fit when | You're fixing one trouble spot | You want room-by-room control | You'd rather not see indoor units at all |
| Coverage when we install | Up to 12 years on Mitsubishi parts and compressor | Up to 12 years on Mitsubishi parts and compressor | Up to 12 years on Mitsubishi parts and compressor |

We decide where each head goes by how the room is used, where the sun hits, and where the furniture sits. We also plan a tidy path for the lines outside. The result is even air, without drafts blowing across your bed or couch.
We hold Mitsubishi Electric's Elite Diamond Contractor status. That means the systems we install carry up to 12 years of coverage on parts and the compressor. When something needs attention later, you call the same team that put it in.
Your written quote breaks the cost down by zone, so you can start with the room that bothers you most. We can size the outdoor unit so more heads can join later. New installs can qualify for 0% financing for 36 months.
Booking a mini-split installation or replacement starts with one in-home visit and a written quote. From there, most of the work happens outside and along one wall, so the rest of your home stays untouched. Here's each step, from the first walkthrough to the final test.
Step 1
Show Us Where It's Too Hot or Cold
Book a visit by phone or online. We walk through the house with you and note which spaces run too hot, too cold, or both.
Step 2
Weigh the Options, No Rush
Your written quote spells out each zone, the equipment, and the financing in plain terms. There's no deadline and no pushy follow-up, just a clear quote to think over.
Step 3
Mounted, Connected, and Sealed
We mount each indoor head, set the outdoor unit, and run the lines through one small opening per head. For a replacement, we recover the old refrigerant as EPA rules require.
Step 4
Your Remote, Explained
We test heating and cooling in every zone, then clean up the work area. Before we go, you'll know the remote, the filters, and what your coverage includes.

Ring us any time, and our team notes which rooms lost heat or cooling. Office hours run 8 to 5, and we book your in-home estimate at the first open slot. After hours, maintenance plan members can get emergency repairs at an after-hours rate.
If the old unit can run a few more weeks with a minor repair, we'll price it for you. You can then compare new systems without a room sitting hot or cold.
The outdoor unit's label lists the model and often the year it was built. Send a photo when you book, and we can plan your options before we arrive.

A single-zone ductless mini-split usually costs about $4,000 to $7,000 to install. Multi-zone systems often run $10,000 to $25,000, depending on the heads, line length, and electrical work. KO HVAC gives you a written, zone-by-zone estimate after an in-home visit.
Most homes need one indoor head for each room or open area you want to control separately. An open first floor might share one head, while bedrooms usually get their own. We map it out during the visit, so you're not paying for heads you don't need.
Yes, a mini-split can heat your home through a Pennsylvania winter, as long as it's a cold-climate model. Mitsubishi's cold-climate systems are rated to keep heating in outdoor temperatures well below zero. Some homeowners here use one as their main heat, with a backup for the coldest stretches.
Mini-split installation for a single zone is often finished in one day. Multi-zone and ducted systems can take two days or more, depending on the house. You'll get a timeline with your estimate, so you can plan around it.
Yes, mini-splits work well in older homes without ductwork, and they're one of the best options. Each indoor head connects to the outdoor unit through a small opening, so no walls need opening for ducts. That makes ductless a natural fit for radiator-heated homes around Kingston.
During a replacement, we recover your old mini-split's refrigerant as EPA rules require, then remove both units. Sometimes the new system can reuse the existing copper lines, which we check first. Either way, we clean up before we leave.
A new Mitsubishi mini-split we install comes with up to 12 years of coverage on parts and the compressor. Full coverage depends on proper installation and, in many cases, registration. We walk you through what's covered before we leave.
