HVAC digital marketing case study
How we grew conversions by 215.79% in three months for our HVAC client?
Client overview
A strong business ready for a stronger acquisition system.
An established heating and cooling company serving homeowners and businesses across its region. The team was known for dependable installation, maintenance, and repair—but its digital campaigns were not producing dependable demand.
The challenge
The campaign had to create sales during the HVAC off-season, with only three months to prove the model and improve performance.
Our digital marketing solution
Build a tighter paid-search funnel around urgent service intent.
Yellow restructured the PPC funnel around the services and search moments most likely to produce calls. Keyword bidding, negative keywords, ad groups, and landing-page messages were aligned to one conversion plan.
Research and A/B testing shaped a stronger promotional offer and clearer calls to action. Budget was moved toward the ads, audiences, and locations demonstrating the best commercial intent.
How we did it
Ten coordinated moves created one faster route to qualified calls.
The three-month sprint connected research, local visibility, content, and paid media around a single conversion target. Weekly performance reviews helped the team identify wasted spend quickly, strengthen the best-performing messages, and keep every channel focused on qualified service calls.

Spend less and earn more
A more relevant click became a more valuable service call.
The winning change was focus. Better keywords, clearer offers, and disciplined bidding helped the company reach people already looking for heating and cooling support.
That relevance improved interaction, reduced wasted spend, and gave the client a repeatable system for generating demand outside its busiest season.
I couldn't recommend the team more highly. Their work is impeccable and their communication is incredibly professional.
