You have a limited marketing budget. Where should you spend it? Here's the 2026 ranking of HVAC lead sources by ROI — based on industry averages and real CoolerDesk client data.
LSAs put you at the very top of search with a Google Guaranteed badge. Pay per lead, not per click. Average cost: $25–$60 per lead. Conversion rate: 30–40%.
Your website traffic is already paid for. A chatbot converts 5–15% of visitors into leads vs. 1–2% for a contact form. Cost: included in your site plan.
Free to claim. Optimizing your GBP with photos, posts, and reviews drives massive local traffic. The #1 source of phone calls for most HVAC companies.
'Give your customer $50, get $50.' Low cost per acquisition. The leads close at 70%+ because trust is pre-built.
Your past customers are gold. Send seasonal maintenance reminders. Cost: near zero. Close rate: 25–40%.
Good for brand awareness and maintenance plan sales. Less effective for emergency repairs. Average cost per lead: $15–$40.
Expensive ($8–$20 per click) but high intent. Best paired with a chatbot to capture the traffic immediately.
Postcards still work in some markets. High cost per piece but good for seasonal promotions.
Expensive leads ($30–$80 each). Quality varies. Use sparingly for overflow during peak season.
Hard to track. High cost. Better for brand building than direct response.
Invest in the sources you can control and measure. Every dollar on LSAs, GBP, and your own website (with a chatbot) generates the highest return.
