Complete Google Ads Guide for HVAC Businesses (2025)

A clear, step-by-step Google Ads playbook for HVAC companies in 2025 — how to set up Local Service Ads, search campaigns, keywords, landing pages, budgets, tracking, and seasonal strategies so you get more calls, booked jobs, and higher ROI.

Why Google Ads work for HVAC companies

HVAC searches are urgent: broken AC in July, furnace failure in January.
68% of homeowners turn to search engines first when facing urgent HVAC issues. [S1]

Google Ads reaches those customers at the exact moment they need help. For HVAC businesses, that means:

Reach customers actively searching for service (high intent).
Target by location and urgency (same-day / emergency searches).
Pay only for clicks or qualified leads (measurable ROI).
Adjust campaigns instantly based on performance.

Google Ads drives an average ROI of $2 for every $1 spent on home services.

Best Google Ads campaign types for HVAC

1) Local Service Ads (LSAs) — priority #1

LSAs show above regular search results and operate on a pay-per-lead model. They deliver higher conversion rates and include the Google Guarantee — a strong trust signal for homeowners.

Why use LSAs?

Show at the top of results for local searches.
Paid per qualified lead (not per click).
Excellent for phone calls and booked jobs.

Businesses using LSAs report 13–20% higher call booking rates than standard PPC.

“The Google Guarantee is the trust badge homeowners notice first.”

Quick setup checklist

Create LSA account → choose HVAC.
Add services, hours, service area (zip codes).
Upload licenses, insurance, certifications.
Pass background checks and verify business info.

2) Search Ads (PPC) — control + intent

Search Ads give you keyword-level control. Use them for emergency repair terms, installation queries, and commercial work.

Best practices

Use city + service in headlines (e.g., “24/7 AC Repair in [City]”).
Put clear CTAs (Call Now, Book Same-Day).
Build separate ad groups per service.

For home services, including HVAC, the average cost per click (CPC) in 2025 is $7.85.

3) Performance Max / Display / YouTube — scale and awareness

Use Performance Max to combine Search, Display, YouTube, and Discovery inventory. Good for brand awareness, seasonal promotions, and remarketing past visitors.

HVAC Keyword strategy (simple & effective)

High-intent keywords (primary targets)

Ac repair near me
emergency hvac repair
furnace installation cost
heater repair same day

Long-tail keywords (lower CPC, higher conversion)

commercial HVAC contractor in [city]
emergency heater repair near me
Ac installation financing available

Long-tail HVAC queries convert at 70% higher rates than generic keywords.

Negative keywords — protect your budget Add these to avoid irrelevant clicks: diy, tutorial, how to, jobs, careers, free, parts, used, wholesale.

Budgeting & bidding (practical numbers)

Starter budget: $50–$100/day per active campaign.
Installation / replacement campaigns: $150+/day (higher lead value).
Maintenance / tune-ups: $50–$75/day.
Peak season: raise bids by 20–30% during extreme summer/winter.

Average HVAC businesses spend $1,200–$3,000 per month on Google Ads. [S6]

Expected results (benchmarks)

Avg cost per conversion: $25–$150 (varies by market & service).
Avg conversion rate: 2–5% (well-optimized can hit 10–18%).

Smart bidding tip: Switch to Target CPA or Maximize Conversions after ~30 conversions so the algorithm has data.

Ad copy & extensions that drive calls

Winning ad formula

Headline = service + city + benefit (e.g., “24/7 Furnace Repair — [City]”).
Description = proof + offer + CTA (e.g., “Licensed techs, 5-star reviews. Call now for same-day service”).
Urgency + special offers lift CTR (e.g., “Emergency Service — Call Now”).

Example ad elements

Headline: Emergency AC Repair in [City] | 24/7 Service
Description: Licensed HVAC techs. Same-day repairs. 5-Star reviews. Call now for a free estimate.

Must-use extensions

Location extension (show address).
Call extension (one-tap mobile calls).
Sitelink extensions (AC Repair, Furnace Install, Maintenance).
Callout extensions (“24/7”, “Free Estimates”).
Price extensions (show typical tune-up price / financing).

Geography & audience targeting

HVAC is hyper-local. Use:

Radius targeting (10–25 miles depending on service area).
Bid adjustments for high-value ZIP codes.
Exclude low-ROI neighborhoods.
Use household income signals where available (for higher-value installs).

Landing pages that convert (don’t send traffic to the homepage)

Always match the landing page to the ad intent.

Landing page checklist

Clear headline that matches the ad.
Prominent CTA above the fold (Call Now / Book Service).
Phone number clickable on mobile.
Trust signals: licenses, Google reviews, badges, photos of techs.
Load under 3 seconds, mobile first.
Short form (name, phone, service) or click-to-call.
Specific service content (AC repair page for AC ads).

Service-specific landing pages convert 35% better than generic homepages. [S7]

“One page, one purpose — that’s what converts.”

Tracking & analytics — measure what matters

Track these conversions:

Phone calls from ads (use call tracking numbers).
Contact form submissions / quote requests.
Online bookings / scheduler entries.
Revenue per lead (connect CRM or ServiceTitan).

Setup checklist

Link Google Ads + Google Analytics + Google Tag Manager.
Enable conversion import (for offline booked jobs).
Use call tracking that integrates with your CRM.
Tag campaigns with UTM parameters.

Seasonal HVAC ad strategy

Summer: prioritize AC repair, emergency AC, new installs.
Winter: furnace repair, emergency heating, replacement offers.
Spring/Fall: tune-ups, maintenance, preventive plans.
Promotions: limited-time discounts before peak season to capture early bookings.

Common mistakes HVAC businesses make

❌ Tiny daily budgets that don’t collect data.
❌ No negative keyword list (wastes spent).
❌ Mixing multiple services in one ad group (poor relevance).
❌ Generic ad copy with no city or offer.
❌ Sending paid traffic to the homepage instead of a service landing page.

Scaling & measuring ROI

Track cost per booked job (not just lead).
Use CRM data to calculate revenue per lead and true ROAS.
Scale campaigns with positive ROI gradually — increase budgets where CPA is acceptable.
