“Swapping our aging oil furnace for a heat pump felt daunting, but they handled the removal, rebates, and paperwork. Our heating bills dropped noticeably the first month.”

Why Homeowners Call Us
Hot St. Thomas nights and bedrooms that never cool down?
Ductless AC installation delivers efficient, flexible cooling where ductwork can't go, cutting energy waste and keeping every room comfortable on the hottest afternoons.
Flexible Scheduling and Fast Turnarounds
Most single-zone ductless installations are completed in a day, and multi-zone projects rarely run longer than two. We arrive with every component on the truck, protect your floors, and leave each workspace clean and tested.
Keep Your Mini-Split Running Efficiently
Ductless systems thrive on simple care: rinse the washable filters monthly, keep the outdoor coil clear of leaves and snow, and book an annual tune-up. A maintained mini-split holds its efficiency and its warranty coverage far longer.
We Know the Local Housing Stock
From century homes near the main street to new subdivisions on the edge of town, we know the housing stock across St. Thomas and Middlesex County. That local knowledge shapes placements that work and installs that age well.
FAQ
Ductless AC Installation in St. Thomas: Common Questions
How much does ductless AC installation cost?
It depends on zones, equipment tier, and mounting details. A single-room system costs far less than a multi-zone setup. Every estimate we provide is free and written.
How long does a ductless AC installation take?
From booking to cool air, most projects wrap within two to three weeks. The install itself is the short part; equipment availability and your schedule set the timeline.
Should I repair or replace my mini-split?
If the compressor is shot or refrigerant leaks keep recurring, replacement usually makes sense. For a unit under ten years with a simple fault, repair is often the smarter call.

“Furnace refused to ignite on the first really cold morning. They diagnosed the failed igniter from my description, arrived with the part on hand, and we were warm by lunch.”
