Google Ads vs Meta Ads for HVAC: Where Each One Actually Wins

Most HVAC contractors either pick Google or Meta and stick with it religiously, or try to run both the exact same way and wonder why one's printing money and the other is burning it. Both are mistakes. Here's how to think about it.

The one-line answer

Google wins on intent. Meta wins on demand generation. Emergency service calls happen on Google. Install and maintenance-plan sales start on Meta. You need both — but running them with the same creative, the same funnel, and the same offer is how you waste half your budget.

What each channel is actually good at

Google Search: the emergency funnel

When someone's AC goes out at 9pm in July, they grab their phone and type "AC not cooling" or "HVAC repair near me." That's Google's home turf. Queries are short, urgent, and convert fast — usually within the same hour.

• Best for: service calls, emergency repairs, same-day dispatch
• Typical CPL: $35–$90 depending on market
• Conversion window: under 24 hours
• Call volume is everything — dynamic call tracking is non-negotiable

Google LSAs (Local Service Ads): the trust multiplier

LSAs stack ABOVE the regular search results with the Google Guaranteed badge. Pay-per-lead, not pay-per-click. For HVAC specifically, LSAs are often the highest-ROI channel once you get ranked — but ranking requires optimization most contractors ignore (response time, review velocity, dispute rate).

• Best for: any service calls, especially repair and maintenance
• Typical CPL: $30–$75 (pay-per-lead, so this is all-in)
• Trust signal from the green check is worth ~20% higher close rates

Meta (Facebook + Instagram): the install funnel

Meta doesn't win on emergency intent — no one Facebooks "my AC broke." But it dominates for system replacements, installations, and maintenance plans. Homeowners scroll past your ad, see efficiency rebates or financing, click, and enter your funnel. That funnel takes 2–8 weeks to close but averages 3–5x the ticket size of a repair.

• Best for: install leads, replacement leads, maintenance plan signups
• Typical CPL: $40–$120 (but pre-qualification matters way more than CPL)
• Conversion window: 1–8 weeks
• Retargeting is where the real money is — 60%+ of your closes will happen on retargeting touches

YouTube: the trust layer

YouTube isn't a direct-response channel for HVAC, but it's a phenomenal warm-up layer. Educational content on efficiency ratings, financing options, what a replacement actually costs — feeds your retargeting pool and shortens sales cycles on Meta.

How to split budget

Here's the approximate split we run for most established HVAC contractors at a $5,000/mo ad spend level:

The three mistakes we see over and over

1. Running the same creative on both channels. An emergency repair ad doesn't belong on Instagram. A replacement financing ad doesn't belong on Search. Separate creative for separate intent.
2. Ignoring retargeting. Most HVAC contractors turn off retargeting "because it didn't convert." Retargeting doesn't convert on last-click attribution. But 3 months later the homeowner books, and retargeting is the reason — if you had it running.
3. Not separating service from install at the campaign level. Mixing service and install leads in the same campaign means Google's bidder optimizes for whichever is cheaper, which is usually service. Your install lead volume dies.

Bottom line

Pick Google if you only run service calls and have tight response time. Pick Meta if you only sell installs and have sales follow-up dialed. Run both if you want to grow — but run them with separate strategies, separate creative, and separate KPIs.
