2 of 3 details stated on their own site — their claims, not our checks
Not counted — no bonus earned, and nothing deducted
Our own calculation, not Google’s and not the contractor’s. Ratings from few reviews are held closer to average, because a handful of five-star reviews is not the same evidence as a long record. The items above can only add to a score, never subtract from one: a contractor scoring nothing on all of them still reaches 80 out of 100 on a strong rating alone. “Not counted” means we have no bonus to award, not that anything is wrong.
Their website says it has been working since 1979 and advertises 24/7 emergency cover.

Taken from their own website (wiehler.ca), read on September 9, 2026. These are the company’s statements about itself, quoted from the page — not claims we have checked. Ask to see a licence before any gas work.
“Founded by Marty Wiehler in 1979, the company has grown to over 100 staff members. Wiehler has the highest Google rating in Calgary, and no one beats their 5 Star Customer Service! As Calgary’s premier plumbing and HVAC contractor, Wiehler Mechanical specializes in Custom Homes, Commercial, New Builds and residental Service. Marty’s son, John, joined the company in 1999 as an apprentice and now uses his first-hand knowledge of plumbing as the President of the company. In 2014, Marty’s second son, Eric, also joined, making Wiehler Mechanical a true family business. The Wiehler team continues to collaborate with high-end custom builders and their clients to create some of the most impressive and beautiful homes in Calgary.”
