GreenON incentives within the Heating and Cooling Program

The additional incentive amount offered within the Save on Energy Heating and Cooling Program offered by the IESO on behalf of the Green Ontario Fund will be ending. As such, the incentive structure first introduced in July 2017 will take effect. The Save on Energy Heating and Cooling Program measures that were not funded by the Green Ontario Fund will continue to operate according to the current program rules. As a Save on Energy Heating and Cooling participating contractor, this means that:
  • You should cease any sales or promotional efforts that reference the GreenON incentive top-ups, and revert to offering the Heating and Cooling incentive values introduced in July 2017 and referenced in Appendix A of the Heating and Cooling Contractor Participation Agreement. You should also remove any references to the GreenON incentives from your website and in other promotional materials.
  • Rebate applications already submitted will continue to be processed with the GreenON incentive top-up according to eligibility criteria.
  • New rebate applications will not be processed with the GreenON incentive top-up without proof of a firm commitment between the customer and a Save on Energy Heating and Cooling participating contractor being in place on or before June 19, 2018. While installations will need to be complete by August 31, 2018, contractors and customers have until September 30, 2018 to submit these rebate applications to the IESO.

Ontario Helping Everyone Fight Climate Change

Ontario is investing proceeds from its carbon market to help researchers, companies and families reduce their greenhouse gas emissions (GHG) and fight climate change in Ontario through several innovative programs. 

Reza Moridi, Minister of Research, Innovation and Science, was joined by Chris Ballard, Minister of the Environment and Climate Change, at the Clean Tech showcase at Ontario Centres of Excellence's Discovery conference in Toronto to highlight a range of programs that people and businesses across the province can access to fight climate change.

There are now 22 successful recipients for Ontario's Low Carbon Innovation Fund, which includes two streams of support:

  • Technology Demonstration — supports the development and commercialization of innovative low-carbon technologies through demonstration in real-world settings. There are 10 approved projects, including one that uses artificial intelligence to optimize energy storage systems in buildings and reduce GHG emissions
  • Technology Validation — funds proof of concept or prototype projects from companies or academic organizations, helping to seed game-changing technologies and get them to market faster. There are 12 approved projects, including a technology that enhances aerodynamics to increase the efficiency of wind turbines.

Ontario is also launching two programs through the Green Ontario Fund (GreenON) to help people and businesses improve energy efficiency and save money while fighting climate change:

  • GreenON Small and Medium Businesses — a technical expert will offer businesses a no-cost energy audit starting this summer and recommend energy-saving measures for buildings and operations, as well as opportunities to apply for funding to implement these measures.
  • GreenON Solar Rebates —rebates for Ontario families and businesses to install solar panels and solar energy storage. Households and contractors can sign up for additional information alerts.

Ontario also announced a TargetGHG-funded project through the Collaborative Technology Development Program. The project involves energy storage developer NRStor with technology supplier Hydrostor and research partners at the University of Waterloo, who propose to build a new facility in Goderich to provide the Ontario electricity grid with more energy storage.

Supporting good jobs, helping companies innovate and fight climate change are part of the government's plan to support care, create opportunity and make life more affordable during this period of rapid economic change. The plan includes free prescription drugs for everyone under 25, and 65 or over, through the biggest expansion of medicare in a generation, free tuition for hundreds of thousands of students, a higher minimum wage and better working conditions, and free preschool child care from 2 ½ to kindergarten.


  • A total of $28.1 million has been allocated for the Low Carbon Innovation Fund: $12.9 million for the Technology Demonstration stream, and $15.2 million for the Technology Validation stream.
  • Through the Climate Change Action Plan, Ontario has committed up to $1.7 billion over three years to support a wide range of programs under the Green Ontario Fund.
  • Approximately $90 million has been designated for the solar rebates program, and approximately $40 million has been designated for the small and medium businesses program.
  • TargetGHG is funded through proceeds from Ontario’s carbon market and administered by Ontario Centres of Excellence. It is designed to help Ontario reduce its GHG emissions by helping large industries adopt leading edge technologies and supporting entrepreneurs developing creative new solutions.
  • The new TargetGHG project in Goderich is supported by $1 million from the Ontario Centres for Excellence, for a total project value, including partners’ cash and in-kind contributions, of $7,195,422.
  • Ontario has selected two venture capital fund managers through the Ontario Capital Growth Corporation (OCGC) to help clean tech companies get the capital they need to grow their business and create jobs. OCGC has invested $20 million in Yaletown Partners’ Innovation Growth Fund and has committed $35 million in Emerald Technology Venture’s Canadian Cleantech Fund.
  • Ontario has the fastest-growing clean tech sector in Canada, with $18.8 billion in revenue, 5,000 companies and 130,000 employees.

The Climate Change Action Plan and carbon market form the backbone of Ontario's strategy to cut greenhouse gas pollution to 15 per cent below 1990 levels by 2020, 37 per cent by 2030 and 80 per cent by 2050.

Leaking evaporator coil is the problem

Formicary or “ants’ nest” corrosion on the outside of air conditioning coils is not new, but it is becoming such a problem that members of one Ontario contractor group have decided that they will only install equipment with aluminum evaporator coils.

“We have had a lot of issues with it,” remarked Dave Murtland, owner of D&B ClimateCare in Simcoe, Ont. “It can happen only a few months after putting it in.”

“We’ve had to replace new equipment coils in year one, two and three,” added Nancy McKeraghan of Canco ClimateCare, Newmarket, Ont.

“When contractors come back in the spring (to do the spring AC service) they are seeing significant refrigerant depletion,” reported Mario Bernardi, ClimateCare executive director. “They’ve got storage rooms full of coils that they’ve removed.”

Last fall the ClimateCare Co-operative, a group of 34 independent Ontario HVAC contractors headquartered in Burlington, Ont., decided to go aluminum only for evaporator coils in their private label air conditioning equipment. With parts and labour warranties up to 12 years, they will simply not sell equipment with copper coils. “That way we can eliminate the corrosion,” said Murtland.

A perfect storm

It’s important to note that the issue doesn’t affect the equipment of only one manufacturer; most, if not all, of the majors have been affected. A multitude of factors have come together to make failing evaporator coils a significant problem in the past three years, reported Glenn Mellors, ClimateCare director of training and implementation.

These include indoor air quality and tighter homes. Volatile organic compounds (VOCs) that gas off from carpets, building materials, furniture, etc. combine with oxygen and moisture to create an acidic solution that reacts with the copper to cause pinhole leaks. “The homes are tighter and there are not enough air exchanges. It slowly eats away at the coil,” said Murtland.

The problem is worse in areas with poor outdoor air quality – pollution, added Mellors. Cases of formicary corrosion are higher in industrialized southern Ontario than in the Ottawa Valley, for example.

In some cases, manufacturers have modified the copper coils to improve efficiency, using thinner wall and/or rifled copper tubing to maximize heat transfer.

“It all has to do with, in my mind, the striving for higher efficiencies,” said Mellors.

No visible signs

Formicary corrosion can easily be identified if it is on the outside of a coil. It appears as a dark stained “soil” buildup around the leak. When the corrosion is internal, it’s a different matter. Often, when a technician diagnoses an air conditioner suffering from formicary corrosion, there are no visible signs, but the refrigerant level is low. “It’s almost like the refrigerant is leaking by osmosis,” said Mellors.

The quick and dirty fix is to just “fill and go,” or perhaps add a leak sealant and then fill. That might get the coil through the warranty period, but it’s going to leave one very unhappy homeowner faced with a problem that can only get worse. It’s unprofessional and not something ClimateCare contractors would do, added Mellors. So, they replace the coil, typically losing money on every warranty repair.

It’s a big job, typically taking a full morning, noted Peter Steffes, long-time Windsor, Ont. contractor and, today, supervisor of commercial sales for Vollmer Inc., Windsor, Ont. And yet manufacturers will only cover two hours labour. To make matters worse, getting the warranty approved can be difficult because of the lack of visible damage. “They ask you to take a picture of the coil and show where the break is,” remarked Bernardi. “Warranty is a big cost. It’s very onerous.”

Solution slow in coming

Contractors have been frustrated because manufacturers have been slow to acknowledge the problem, added Murtland. Or, as Mellor says, “they’ve been in denial” due, in part, one would expect, from a number of lawsuits in both Canada and the U.S. over formicary corrosion.

That being said, some time ago Carrier released a report titled Indoor Coil Corrosion. The company also offered a solution in the form of tin-plated copper coils. Some other manufacturers adopted aluminum coils.

However, the switch to aluminum has taken time because manufacturers had to have those coils certified as a match with their equipment so that the homeowner could qualify for energy efficiency rebates. It’s an expensive and time-consuming process. Getting each coil certified with each air conditioner costs thousands of dollars. Some manufacturers still don’t have a full line of aluminum coils, noted Murtland.

And while aluminum may not suffer from formicary corrosion, other issues may come up down the road. “I am not that sold on aluminum either,” said Steffes, who installed many air conditioners with aluminum coils in the 70s. They are more difficult to repair. “You can do it, but you’ve got to have a lot of finesse.”

Consumer anger

Failing air conditioners are a major topic on consumer and homeowner blogs. As noted above, some manufacturers are facing or have faced class action lawsuits either in Canada or the U.S. Johnson Controls recently settled one U.S. lawsuit. Among other conditions of that settlement, if a homeowner has a copper coil fail twice within the five-year standard warranty or ten-year extended warranty period, it will be replaced with an aluminum coil free of charge,

Much of the anger has, not surprisingly, been directed at installing contractors. “We’re telling the homeowner that their new air conditioner will run for years,” said Murtland. Needless to say, when homeowners run into leaking evaporator coils within the first few years, they are not happy.

“As an industry, we have to wake up and say we aren’t going to use a product that won’t last in newer homes,” says Murtland.
