Mini Split Heat Pump Installation in Durham Region
Ductless mini split heat pumps are a smart way to add quiet, efficient heating and cooling without major ductwork. They shine in additions, home offices, suites, and rooms that never feel right on the main system. This guide explains what a professional installation looks like in real Durham Region homes.

When a mini split is the right choice
Choose a mini split when you want targeted comfort with independent control, when a space lacks ducts, or when you need a fast, tidy install during a renovation.
Single zone systems serve one room very well. Multi zone setups share one outdoor unit across several rooms, which is useful for additions or multi level layouts. If you already have central air, a mini split can solve problem rooms without reworking the whole duct system.
What happens on installation day
The visit starts with placement, both indoors and outdoors. Inside, we mount the wall head high enough for good throw while avoiding crown moulding, TVs, and heat sources. Outside, we choose a location with clear airflow, a solid stand above typical snow height, and a safe path for defrost melt.
A small cored opening carries the insulated line set, control cable, and condensate drain to the exterior. The line set then runs in clean covers to the outdoor unit. We pressure test with nitrogen, pull a deep vacuum, confirm the system is tight, and complete the electrical connection at the disconnect and panel.
Startup includes verifying refrigerant conditions, checking condensate, setting fan and temperature preferences, and walking you through the remote or app.
Sizing and placement that feel better
Right sizing matters more than you might think. An oversized head can short cycle and leave the room clammy. We match capacity to the room’s load, then pick a wall that throws air across the main use area rather than along a short wall.
For tricky rooms, a ceiling cassette or floor console can solve layout challenges while keeping the look clean.
What to expect in winter
Modern mini splits heat well below freezing. You will notice longer, quieter run times and even room temperatures. On damp days the outdoor coil will defrost for a few minutes and you may see a little steam. That is normal.
Keep shrubs and snow away from the outdoor unit and make sure melt water has a place to go. For whole home winter coverage, many homeowners pair a ductless zone with a central system or use a hybrid plan that brings a furnace on only during deep cold.
Electrical, permits, and timelines
Most installations require a dedicated electrical circuit sized for the equipment. We coordinate with your electrician and local inspection so the project meets code.
Typical single zone projects finish in a day with light patching, while multi zone systems can take longer depending on line routes and wall finishes.
Noise, filtration, and maintenance
Heads run at low speed for much of the day, which keeps sound down and filtration steady. Clean the washable room filters every few months and keep the outdoor coil clear. An annual tune up protects efficiency and confirms drainage, electrical components, and performance.
Pricing, rebates, and larger plans
Every home is different, so we provide a written range after a short site review. Rebates may reduce upfront cost for qualified heat pump projects, and flexible financing is available. Start here:

Work with HVAC Zack
We size the room correctly, plan neat line routes, set equipment for quiet operation, and document the final settings so future service is simple. If you also have comfort issues elsewhere in the home, we can compare a single mini split to a broader plan that includes duct tweaks or a central heat pump.
