“Here’s my experience with Green Approval Solution, shared clearly and honestly:

Initial Contact & Expectations

I first reached out to them when I was looking for a service to help streamline approval workflows for business documents, as our manual process was slow and prone to errors. Their website and initial sales presentation were professional — they claimed to offer automated routing, digital signatures, compliance tracking, and integration with common tools we already used, which sounded like exactly what we needed.“

“Can't recommend Alex enough. He came by to check out an issue with our heated floor - he came by was honest & thorough - I came away very impressed and found him very trustworthy“

“We went to Design Air on the recommendation of a neighbour. After numerous other companies either just ghosted us after the first visit or could not find a simple way to deal with replacing our furnace and A/C these guys came in and were not fussed in any way by the job. They quoted quickly and fairly and were very responsive. Their installation team was the nicest group of service providers I have ever had in my house. Very old school customer service. The did everything they said they would do, on time and as -quoted, required zero micromanagement and left no trace other than a brand new furnace and AC that is working just fine.“

“Great thanks to the sales consultant Al for his knowledge and patience choosing the right option for us.
Separate huge Thanks to the crew of installers (Mo and two other gents) for a clean job with venting outside, securing the fireplace and testing everything. Quick service, great prices and very smooth process overall.“
