Google Ads for contractors is not a mystery. You pay per click, clicks cost real money, and most contractors either overspend or underinvest because they don't know what the numbers should look like.
Here's what you'll actually pay, why the range is wide, and how to set a budget that generates leads instead of disappearing into Google's pocket.

What Contractors Actually Pay Per Click
These are real ranges based on the Google Ads auction market in 2026. Your specific cost depends on your market, your Quality Score, and who you're bidding against.
HVAC — $8-40 per click Highest competition in the trades. Emergency AC repair in Phoenix in August can hit $60+. Off-season and installation keywords are cheaper. Maintenance agreement searches are often under $10.
Plumbing — $6-30 per click Emergency plumbing (burst pipe, no hot water) is expensive. Routine work (installation, remodel rough-in) is cheaper. "24 hour plumber" keywords can run $25-45 in major markets.
Roofing — $10-50 per click Storm season drives prices up fast. Replacement keywords are pricier than repair. Solar roofing is in its own stratosphere — $30-80+ per click in some markets.
Electrical — $6-25 per click Panel upgrades and EV charger installation are the expensive keywords. General electrical and outlet/switch work tends to be cheaper.
Tree Service — $4-18 per click Lower competition than HVAC or roofing. Emergency tree removal spikes in summer and after storms. "Tree removal cost" keywords convert well because they attract buyers, not browsers.
Landscaping — $3-15 per click High variability by service type. Lawn maintenance is cheap and competitive. Design and install projects are pricier. Geographic modifier keywords (city + landscaping) tend to be cheaper than generic terms.
Garage Door — $5-22 per click Strong emergency demand (opener broken, door stuck). Repair keywords tend to convert better than replacement, which attracts more price shoppers.
Pest Control — $4-20 per click Termite and rodent keywords carry a premium. General pest control is cheaper but higher volume.
General Contractor — $8-35 per click High competition for broad terms. Niche keywords (kitchen remodel, home addition, ADU) are where most GC budgets work better.
Why You Might Pay More or Less Than These Benchmarks
Quality Score
Google grades every keyword in your account on a 1-10 scale. It measures three things: expected click-through rate (does your ad get clicked when it shows?), ad relevance (does your ad match what someone searched?), and landing page experience (does the page people land on match what they were looking for?).
A contractor with a Quality Score of 8 might pay $8 for a click. A contractor with a Quality Score of 4 might pay $22 for the exact same placement.
The formula: your actual cost per click is roughly (competitor's bid × competitor's quality score) / your quality score + $0.01. You pay less than your bid when your quality score is high.
How to improve your Quality Score:
- Write ads that match what people search (use the keyword in your headline)
- Send people to a page about that specific service, not your homepage
- Make your landing page load fast on mobile
Your Market Size
Small market in Ohio: $4-6 per click for HVAC.
Competitive suburban Chicago market: $28-40 per click for HVAC.
More contractors bidding = higher prices. This is why budget matters — you need enough clicks to compete and gather data, and markets with higher CPCs require higher minimums to do that.
Time of Day and Day of Week
Emergency service keywords peak in price evenings, weekends, and holidays — when homeowners discover problems and competitors are all fighting for the same searches. Scheduling your ads to only run when you can actually answer the phone is one of the easiest budget optimizations available.
How to Set a Realistic Budget
Most contractors need a minimum of $1,500-3,000/month to run a Google Ads campaign that generates usable data. Below that, your budget runs out mid-day, you miss peak search times, and you never accumulate enough clicks to know what's actually working.
A simple budget calculator:
- Estimate your expected CPC from the ranges above
- Multiply by 100-150 (clicks per month needed for statistically useful data)
- That's your starting monthly budget
Example:
- HVAC in a mid-size market — expect $15 CPC
- 150 clicks × $15 = $2,250/month
- That's about 4-6 leads per month at a 3-4% conversion rate (industry average for a well-built landing page)
If a lead converts into a job at your close rate, and that job is worth $800-3,000, the math usually works — but only when the campaign is properly set up and tracked.
The Biggest Ways Contractors Waste Money on Google Ads
1. Sending all clicks to the homepage Conversion rates for contractor homepages are typically 1-2%. A dedicated landing page (one service, one CTA, phone number above the fold) runs 4-8%. That's 3-4x more leads from the same spend.
2. No negative keywords Without negative keywords, you'll pay for clicks from "DIY plumbing," "plumbing school near me," "plumbing jobs," and people looking for the business your customer works for. Building a negative keyword list is week-one work on any campaign.
3. Running 24/7 when you only answer 9-5 If you don't answer when someone calls, they call the next contractor. Either run call extensions and someone answers the phone, or schedule ads to run when you're available.
4. Broad match with no supervision Broad match keywords generate the most impressions and often waste the most money. They match your keyword to searches Google thinks are "related" — which can be very loosely interpreted. If you use broad match, check your search terms report weekly for the first month.
5. Not tracking calls Google Ads call tracking tells you which keywords generate phone calls. Without it, you're optimizing toward clicks, not leads. Call tracking is table stakes. Set it up before you launch.
When Google Ads Makes Sense for Contractors
Use Google Ads when:
- You have a solid Google Business Profile and decent review count (ads convert better when people can verify you're real)
- Your website has service-specific pages that load fast on mobile
- You can track calls back to specific campaigns
- You have budget to run for 90+ days before expecting ROI (campaigns need optimization time)
- You need leads faster than SEO can deliver them
Don't use Google Ads yet when:
- You have fewer than 10 Google reviews (you'll get clicks, but trust will kill your conversion rate)
- Your website is a homepage with a contact form and nothing else
- You can't dedicate time to monitoring and optimizing the account weekly
- Your budget is under $800/month (too thin to generate useful data in most markets)
The contractors who get the best ROI from Google Ads are the ones who built their local SEO foundation first. Better reviews, better website, better GBP — all of these improve the conversion rate from paid clicks, which drops your effective cost per lead even if your cost per click stays the same.

Google Ads vs. Local Services Ads
Two different products. Local Services Ads (LSA) charge per verified lead, not per click. Regular Google Ads (Search) charge per click regardless of whether the visitor becomes a lead.
For most contractors, the order is:
- Fix your GBP and build reviews (free)
- Add LSA if your category qualifies (pay per lead, higher conversion intent)
- Add regular Google Search Ads once your foundation can support the conversion rate
Running regular Google Ads without the foundation in place burns money. Running them with a solid GBP, 25+ reviews, and a fast website turns them into a reliable lead channel.
