We are concerned about the ongoing warranty situation. We installed the combi-water tank system in 2018, which is supposed to be under a 12-year warranty. We have been having annual maintenance with ACCUSERV to keep the warranty in good standing. Last year, shortly after a maintenance, we began noticing issues with the water tank. We contacted ACCUSERV to address these issues, but they have been pressuring us to replace it to the tankless system instead of repairing the water tank that is covered under the warranty. We have been engaging in back-and-forth phone calls and emails since November regarding these issues. We received an email stating that our issues cannot be covered under the warranty and a quote for repairs which was $11,000. This does not reflect our warranty and required maintenances that we’ve been doing for years. We thought we found a good company, but unfortunately, it turned out not to be the case. We are so disappointed.

At 71, this is my first ever review. I purchased a Navien 240 Combi boiler 9 years ago, not from AccuServ . Within 3 days of the install we started having various problems. The install company replied you should just "phone Navien customer service they're really good". Just before Christmas 2025 the boiler completely failed and I lucked out when I called the AccuServ shop on Woodbine ave to come and assess the problem. First they sent a technician, Habib. His work was exceptional, he went through the problems with me and showed me how poorly the first install was done. He got on the phone to Navien Canada and explained the problems. To my surprise he secured a replacement boiler under warranty. You can imagine my shock that this was 9 years after my purchase. What company shows this level of support? A few weeks later, (my call), a crew from AccuServ came and installed the new boiler. Every person I had to deal with at accuserve was knowledgeable polite and very helpful in explaining exactly what was going on. I wish I had kept a photo of the original install so I could show you the comparison, let me tell you there was none. All of the copper work was square, plumb and clean with ample space to adjust any of the valves. All adapters were ProPress units and although expensive the finished product speaks for itself. A special thanks to Simon, Roz and Ali, who did the new boiler install. If you're planning to do any HVAC work on your property, be very careful about any company that starts with Q's and save yourself some grief by using AccuServ.

I purchased the monthly plan for my furnace, AC and Tankless Hot Water Heater and any tech that comes out in the Spring and Fall has been great! Earlier in the summer they recommended a permanent filter which we take out every 3 months to clean. It has already paid for itself. Yesterday the furnace started leaking water and within 24 hours the tech came over and fixed it - it was all covered by the plan. I have had consistently great service from them and highly recommend them.

Brought in AccuServ about a month ago to replace my furnace. Decided to go with them because they’re local. I felt the install was really poor - they originally installed the exhaust vent below the intake on the side of the house, right next to the bathroom exhaust. I called that out and they corrected it before they left. When I looked further at the install I noticed no strapping on any vent pipes - it was using existing electrical wire for support and had a low spot right next to the furnace where condensation would collect. The furnace itself wasn’t level - I had to bend the filter to insert or remove it. The electrical wiring was going across in free air too. I complained to the sales person and they got a second team out to fix it in combination with the first. Fast forward a month and there is so much condensation in the pipes it sounds like a washing machine - the furnace would turn itself off because it couldn’t exhaust the gases from the house. They came back and fixed it again - this time leaving a 2” screw straight through the century old dining room floor - straight up. Luckily found it before anyone got hurt and they came back again to fix it. As I told Vlad the sales person who sold it to me, who was very apologetic - Every time AccuServ has come I’m left feeling that my house, and my family, is less safe.

My tankless hot water heater died. After calling multiple companies, Accuserv was able to do a diagnostic in 24h. It need to be replaced and they came the next day to installed the new one. It was a really tight install, but they got it done and we are really happy with it.

ODP / refrigerant handling certification

Required to legally purchase and handle refrigerant. Relevant to any AC or heat pump work.

Manufacturer certification for the equipment being installed

Not a legal requirement, but many manufacturer warranties are only valid when installed by a certified dealer. Ask before assuming you have a ten-year warranty.

Questions worth asking

  • Will you perform a heat loss and heat gain calculation, and can I see it?
  • Who on the crew holds the TSSA gas certificate, and at what level?
  • Is the equipment warranty conditional on registration or on installer certification?
  • What exactly is covered by your labour warranty, and for how long?
  • Does this quote include removal and disposal of the old equipment?
