Ductless Mini-Split Installation in Georgetown

Yes. Hyper-heat units (Mitsubishi MUZ-FH/MSZ-FH, Daikin Aurora, Fujitsu Halcyon XLTH) maintain 100% rated heating capacity to about -15°C and continue operating to -25°C without auxiliary heat. Georgetown design temp is -22°C; properly sized cold-climate units cover the heating load for ~95% of winter hours. Standard (non-cold-climate) units lose 50%+ capacity below -10°C and should NOT be used for primary heating.

One head per ~400-600 sq ft of cooled/heated area, with discrete head per bedroom for sleep comfort. Most Georgetown 2-bedroom semis: 2-zone (living + master). 3-bedroom: 3-zone. 4-bedroom + finished basement: 4-zone. Manual J right-sizes — we don't oversell.

Cold-climate mini-split COP ~3.0 average (3 units heat per 1 unit electricity). Georgetown Hydro $0.14-0.18/kWh; Enbridge gas $0.50-0.65/m³. Heat pump heating cost ~$0.045/kWh-equivalent; gas furnace ~$0.038/kWh-equivalent at 96% AFUE. So gas is currently slightly cheaper per BTU UNLESS you stack the rebates — net cost after HRS + Greener Homes loan/grant makes electricity cheaper for most owners. Plus electrification de-risks future gas price hikes and federal carbon pricing.

Yes. Mini-splits are reversible — same units provide cooling in summer. Hyper-heat units also dehumidify well (variable-speed compressor matches latent load). No separate AC needed.

19-28 dBA on lowest fan setting (Mitsubishi M-Series quietest in class — quieter than a library whisper). 35-45 dBA at full speed. Outdoor condenser 50-58 dBA at high speed, 38-45 dBA on low.

Wall-mount heads are 8-12" deep, 30-42" wide, white plastic. They show. Alternatives: ceiling cassette (looks like recessed light, $400-$800/head premium), floor-mount (low-profile baseboard style, $200-$500/head premium), low-static ducted concealed head (mini ductless feeds 1-2 rooms through soffit, $800-$1,400/head premium). Wall-mount is most common because it's cheapest and best at heating.

15-22 years for premium tier (Mitsubishi, Daikin) with annual servicing. 12-16 years for value tier. Annual coil cleaning + filter changes every 1-2 months are critical to longevity.

Mounting bracket must hold unit 12-18" off ground (Georgetown code) — keeps base clear of snow drift. Premium units have base heater for ice prevention. We design mounting placement to avoid roof shed-snow line. Annual snow brushing recommended (homeowner task).

Application must be received by May 31, 2026. Pre-audit must occur first (4-6 weeks lead). Realistic last-call: book the consultation by April 15, 2026 to safely make the deadline. After May 31, only Greener Homes Grant ($5,600) and Greener Homes Loan ($40K interest-free) remain — still a strong stack but $7,500 lower.

Yes, but exterior placement of outdoor condenser and lineset routing may need Heritage Permit (case-by-case). We default to rear-yard placement and concealed linesets via LineHide cover painted to match exterior. Typical HCD approval takes 4-8 weeks; we work it into the project schedule.

TSSA G2 covers refrigerant handling (ODP certification under Ontario Reg 463/10). The refrigerant lineset braze + system evacuation requires the certification — that's why every install goes through a G2/ODP-certified tech, regardless of whether gas is involved.
