Founded in 1978, Day & Night Air Conditioning is a family-owned HVAC and plumbing company based in Phoenix, Arizona.

Their slogan says it best:
“The Difference is Day & Night.”
Phoenix is one of the most competitive HVAC markets in the U.S. with high ad costs, dozens of major players, and aggressive seasonal competition.
Despite their strong reputation, Day & Night needed a modern, trackable system to grow efficiently and turn marketing dollars into booked jobs.
Key challenges included:

Key outcomes:
Their marketing now functions as a self-learning, always-on system powered by data and AI, not guesswork.
Day & Night’s success shows how a long-standing local business can modernize its marketing without losing its identity.
By connecting every digital channel under one sales-first system, they turned their website into a profit engine that drives measurable, repeatable revenue.
G-Site helped them prove that “old-fashioned service” and modern marketing science can work hand-in-hand creating growth that’s both consistent and sustainable.
