Angi vs Thumbtack vs Google LSA for HVAC and Plumbing Leads: Real Cost Per Lead Comparison

The Quick Answer

Google Local Services Ads delivers the highest-quality leads (homeowners who searched specifically for your service and are actively ready to hire) at $20–$80 per lead. Angi and Thumbtack deliver more volume at $20–$100 per lead but send the same lead to multiple contractors simultaneously, creating a price competition dynamic. For HVAC replacement and high-ticket plumbing jobs, Google LSA has the best ROI. For filling schedule gaps quickly with smaller service jobs, Angi and Thumbtack are effective. Use all three in your first 6–12 months, then concentrate budget on the channel with the best cost-per-booked-job in your specific market.

Google Local Services Ads: Cost, Quality, and How It Works

Google LSA leads are generated when a homeowner searches 'plumber near me' or 'HVAC repair [city],' sees your ad with the Google Guaranteed badge, and calls or messages directly through the ad. You pay only for the call — not for impressions or clicks to your website. Lead cost ranges: $20–$45 for minor plumbing service calls in smaller markets, $40–$80 for HVAC service and equipment leads in competitive metros. The critical quality advantage: Google LSA leads are exclusive to the contractors they call. Unlike Angi and Thumbtack (which send leads to 3–5 contractors simultaneously), a Google LSA caller chose your business specifically from the results. Calls from Google Local Services Ads usually book at a much higher rate for responsive contractors than leads from shared-lead platforms. Book rate matters more than cost-per-lead: a $70 Google LSA lead that converts at 65% costs you $108/booked job; a $30 Angi lead that converts at 20% costs you $150/booked job.

Angi (Angie's List) Pro Leads: Volume, Cost, and Reality

Angi (formerly Angie's List and HomeAdvisor after the merger) operates as a shared-lead marketplace — homeowners submit a job request, and Angi sells that lead to 3–5 contractors simultaneously. Lead costs for plumbing: $25–$75 for standard service, $50–$120 for equipment replacement. HVAC leads: $30–$85 for service, $60–$130 for installation. The shared-lead model creates an arms race: whichever contractor calls the homeowner first has the best chance of booking the job. If you're not calling Angi leads within 5 minutes of receipt, you're wasting money, because the fastest responders usually win the job. Angi also sells leads for customers who are clearly price-shopping ('get 5 quotes') — these leads are expensive to convert and generate low average tickets. Advantages: Angi delivers consistent volume and is particularly effective for smaller-ticket service calls and drain jobs. A HomeAdvisor/Angi profile with 50+ reviews also improves organic visibility on the platform, reducing your cost per acquisition over time.

Thumbtack for Plumbing and HVAC: How the Platform Actually Works

Thumbtack operates differently from Angi — customers post jobs and contractors pay to respond (or receive direct matches). Lead cost varies by job type and market: plumbing service $20–$65/lead, HVAC service $25–$80/lead. Thumbtack's algorithm rewards contractors with complete profiles, fast response rates, and high review scores by showing them more relevant leads. The platform skews toward service and repair jobs rather than major equipment replacement — customers looking for a $10,000 HVAC system replacement are more likely to find contractors through Google than Thumbtack. Thumbtack's strongest use case for a new contractor: filling your calendar during the first 6 months before Google reviews and LSA traction builds. The Insights tool (visible in your Thumbtack Pro dashboard) shows demand volume in your category and zip codes — valuable market research even before you start paying for leads. Budget $200–$500/month on Thumbtack initially and track your cost per booked job carefully.

Comparing Platform ROI: A Real Example

Assume a plumbing contractor spending $1,000/month across three platforms receives: Google LSA ($600/month): 12 leads at $50 average, 70% book rate = 8.4 booked jobs, average ticket $420 = $3,528 revenue. Cost per booked job: $71. Angi ($250/month): 8 leads at $31 average, 25% book rate = 2 booked jobs, average ticket $280 = $560 revenue. Cost per booked job: $125. Thumbtack ($150/month): 5 leads at $30 average, 30% book rate = 1.5 booked jobs, average ticket $260 = $390 revenue. Cost per booked job: $100. In this example, Google LSA delivers 3x more revenue per dollar spent than Angi and 2x more than Thumbtack, while also producing the highest average ticket. The result is consistent with broad contractor data — but varies by market, response speed, conversion skill, and review count. Track every lead to revenue in your field service software and reallocate budget to your best-performing channel every 60 days.

Building Your Lead Platform Strategy Over Time

A mature plumbing or HVAC business (12+ months operating, 50+ Google reviews) typically reduces dependence on paid lead platforms as organic channels (Google Business Profile, word of mouth, maintenance agreement base) bring in a growing share of revenue without per-lead costs. The transition path: Months 1–6: spend heavily on Google LSA + moderate Angi/Thumbtack spend to fill the calendar and generate reviews. Months 7–12: as Google reviews build and organic calls increase, reduce Angi/Thumbtack spend and reallocate to Google LSA and a modest Nextdoor budget. Month 12+: rely primarily on Google LSA for paid acquisition, organic Google for inbound, and your maintenance agreement base for recurring revenue. Reserve Angi/Thumbtack for seasonal slow periods (late fall for plumbing in mild climates, shoulder seasons for HVAC). Never completely stop tracking where your leads come from — even as your business matures, regular audit of channel ROI reveals opportunities to reallocate budget.
