“This morning our water heater broke. We placed an online request for a replacement before business hours. They responded to us immediately and within a few hours were at our door with a replacement model. Mark & Brad were very professional, polite, informative and funny. They did a perfect install and left us with practical advice and ways to save money that we didn't know about. And Theresa called often to ensure that we were satisfied and getting the service we needed. Great job. THANK YOU!”

Called for service in the morning with leaking furnace and a representative (Brandon) came to the house just after lunch. Introduced himself and inspected the furnace. Happened to be a back up of condensation from the AC coil. Inspected the coil cleaned the drains and checked subsequent operation. All was good and just need to watch it in the future. Provided me with cost estimates for a new coil and new on demand water heater for future reference. Very professional and recommend! Thanks

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.
Look for consistent reviews across several named sources, not one polished profile.
