★★★★★
SB-12 & ENERGY STAR
AJEC has been instrumental in helping Lakeview Homes achieve our energy compliance goals. Their team’s expertise in SB-12 and ENERGY STAR requirements has made navigating the regulatory landscape straightforward. They respond quickly, communicate clearly, and always find solutions that keep our projects moving forward.
★★★★★
SB-12 & Net Zero
Working with AJEC has been a game-changer for Carey Builders Group. Their deep knowledge of Ontario’s energy codes means we spend less time worrying about compliance and more time focusing on building quality homes. Their reports are thorough, their turnaround is fast, and their team genuinely cares about getting it right the first time.
★★★★★
ENERGY STAR
AJEC’s professionalism and attention to detail is unmatched. From our first ENERGY STAR certification to our most recent development, they’ve been a dependable partner every step of the way. Their pre-construction energy modelling caught issues early that would have cost us significantly down the road.
★★★★★
Net Zero & SB-12
Ballantry Homes has worked with AJEC across multiple Net Zero and SB-12 projects and the consistency has been impressive. They understand the pressure builders face — timelines, trades, inspections — and they work around our schedule, not theirs. I recommend them without hesitation to any builder serious about energy compliance.
★★★★★
SB-12 & ENERGY STAR
I have partnered with Jack on multiple projects that required performance-based energy modeling, and he has been excellent to work with every time. He is incredibly reliable and always follows through on his commitments. His team is responsive and focused on delivering results, which makes a big difference when managing complex design projects. I highly recommend Jack and his team.
★★★★★
CMHC
I have worked with A & J Energy Consultants on more than 10 CMHC-related projects, and the experience has been very positive. Jack and the AJEC team are knowledgeable, professional, and easy to work with. They helped us understand the energy modelling and compliance requirements and supported the projects in a clear and organized way. I appreciate their communication and would be happy to recommend AJEC to others working on CMHC, energy efficiency, or building compliance projects.
★★★★★
CMHC
Our experience with Jack and the hardworking team at A&J Energy Consultants was a great experience. Teamwork and collaboration were a huge part of the process as we worked together to meet energy requirements. The onsite tests went well and staff were friendly, knowledgeable and professional. The team does a great job, not only in assessing the data but also analyzing ways to improve efficiency that go above and beyond, grounded on their combined experience, education and first hand observations. The team managed to meet an urgent deadline which was very much appreciated. We have worked together on two projects and would recommend this team for both large and small projects. On to the next one!
