Choosing a mini-split installer involves two decisions: whether the proposed system suits your home and whether the company can deliver and support that installation. Use this checklist before accepting a quote. Directory profiles can organise your shortlist, but they do not replace a property assessment or independent checks of the business.
List the rooms you want to heat or cool, your existing heating and any persistent comfort problems. Explain whether this is a first installation or a replacement. Give each contractor the same brief; otherwise one may propose a living-area unit while another prices several rooms.
Use our quote-request checklist to prepare the initial enquiry without selecting a capacity yourself.
Have the installer explain how layout, insulation, heat loss and intended room coverage inform the proposal. Ask which spaces will continue using existing heating and how the system will be controlled. The explanation should relate to your property rather than a generic unit size.
For an NL project, TakeCharge’s homeowner guidance describes the importance of an in-home assessment and qualified installation.
Confirm the contracting business name and ask for evidence of the qualifications and insurance relevant to the job. Identify who performs the refrigeration and electrical work, whether subcontractors are involved and who coordinates them. Verify any claimed manufacturer dealer status with the manufacturer.
Requirements differ by location; a listing or a company-supplied badge is not a substitute for checking the applicable authority.
Get exact indoor and outdoor model numbers, locations, electrical responsibility, materials, commissioning and finishing in writing. Ask whether permits, taxes and old-equipment removal are included where applicable. Separate fixed inclusions from provisional allowances and optional upgrades.
The installation guide explains the project scope; the quote comparison guide helps you evaluate competing proposals.
Ask who registers the equipment and who you contact if a problem occurs. Read parts and labour terms separately, including diagnosis, travel, deadlines and maintenance conditions. Request operating instructions and a commissioning record at handover. Keep these with the accepted quote and invoices.
If you already own a system, the repair guide may be a better starting point than a new-installation enquiry.
Browse mini-split companies and use Compare to organise their published details. Current company coverage is in Newfoundland and Labrador. Ask about missing information directly; absence from a profile does not establish that a service is unavailable.
