Crisp uniforms. Smiling technicians. When we looked at the marketing of other Metro Detroit HVAC and plumbing companies, everything looked… the same. But in that crowd we saw an opportunity to make Thornton & Grooms stand out. We did just that with a new brand campaign that put families in the foreground and showed no matter what the weather’s like outside, T&G will keep the temperature inside perfect. Trusted & Guaranteed.
