Why HVAC Google Ads waste so much money in default mode
Most HVAC contractors run a single campaign with broad-match keywords and watch their spend evaporate during shoulder seasons. They bid on "AC repair" and pay for clicks from people researching DIY fixes, parts retailers, and YouTube tutorials. They use the same landing page for emergency and install — which converts neither well.
HVAC Google Ads is a multi-variable problem. Different products. Different intents. Different seasons. Different price points. The fix is campaign architecture — not a higher bid.
The HVAC Google Ads system, section by section
1. Multi-campaign architecture
We split campaigns by intent type:
- Emergency Repair — "AC not cooling," "furnace not heating," "no heat" — bid aggressive, 24/7 ad scheduling, emergency landing page
- Scheduled Repair — "AC repair near me," "HVAC service" — business-hours scheduling, scheduled-service landing page
- Install / Replacement — "new AC install," "furnace replacement cost" — educational landing page with financing CTAs
- Maintenance Contract — "HVAC tune-up," "maintenance plan" — subscription-flow landing page
- Brand — "Trane repair," "Carrier install" — brand-specific copy and pages
2. Negative keyword library built for HVAC
"DIY." "How to." "Parts." "YouTube." "Cost calculator." "What is." "Manufacturer." Each negative kills a click that won’t convert. Most HVAC campaigns have 200–400 negatives — and they update monthly.
3. Day-parting and seasonal scheduling
Emergency campaigns 24/7 with bid modifiers (+25% after hours). Scheduled service business hours only. Install campaigns evening and weekend (when homeowners research). Budget shifts weekly based on weather forecast — heat wave next week? Repair campaigns get the budget.
4. Geographic bidding by ZIP, not radius
Most HVAC operators have favorite zip codes — high-density residential, older housing stock, neighborhoods with central air. We bid up in those zips and down everywhere else. Some operators run premium-ZIP campaigns at +40% bids and shoulder-ZIP campaigns at -30%.
5. LSA integration
LSAs sit above standard PPC and charge per lead, not per click. We manage LSAs alongside PPC, monitoring lead disputes, response time, and review velocity (LSAs reward fast response and high ratings with more lead flow). Many HVAC clients run 60% LSA budget and 40% PPC.
6. Call tracking + landing page CRO
Every campaign launches with dynamic call tracking. Every landing page tested against an alternate. We track booked appointments, not just calls — because some calls are price shoppers and some are buyers. Booked-appointment-rate matters more than call-volume.
