Nelson5.0 / 5 ·

Charton (sales representative)was amazing, very knowledgable and responsive. Lu (the technician) also very good at his job on installation day. Great service and would highly recommend their service!

Robert5.0 / 5 ·

High Efficiency was very responsive to my questions and gave me a very detailed and competitive quote. They are a Carrier dealer and Carrier is the brand I preferred. Other installers seemed to be more ready to put in whatever they had in the shop and were not as familiar with their product as High Efficiency. They arrived on time, did the job neatly and quickly and even registered my warranty for me.

Your own checks

What to check before you hire

Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire.
A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay.
Confirm they cover your area and can actually come out in your timeframe before anything else.
