How Much Should an HVAC Company Spend on Google Ads?

If you run an HVAC company in the Southeast, you already know the phone has to ring. Referrals are great, but they dry up. Slow seasons happen. And your competitors are bidding on your brand name right now while you read this.

Google Ads is the fastest way to put your HVAC business in front of homeowners who need you today. But the number one question we hear from HVAC owners is simple: how much should I actually spend?

Here is a straight answer, no fluff, based on what we see managing HVAC ad accounts across the Carolinas and the Southeast.

The Short Answer: $1,500 to $5,000 Per Month to Start

Most HVAC companies should budget between $1,500 and $5,000 per month on Google Ads to see meaningful results. That range covers ad spend alone, not management fees.

Here is how that breaks down:

• $1,500/month works for a single-location shop targeting one metro area. You will get 30-60 clicks per month and around 8-15 leads.
• $3,000/month is the sweet spot for most mid-size HVAC companies. Enough budget to run search, local services ads, and retargeting without spreading yourself thin.
• $5,000+/month makes sense if you serve multiple counties or want to dominate your market during peak summer and winter seasons.

These numbers assume you are in a mid-size Southern market. If you are in Charlotte, Atlanta, or another major metro, expect to pay 20-40% more per click.

What Drives Your HVAC Google Ads Cost

Your actual spend depends on a handful of factors. Understanding them keeps you from burning cash.

Cost Per Click in Your Market

HVAC keywords are expensive. “AC repair near me” can run $15-45 per click depending on your market. “HVAC installation” often pushes $30-60. Smaller markets like Greenville or Columbia will sit on the lower end. Larger metros push the ceiling.

Your Service Mix

Emergency repair keywords convert fast but cost more. Installation and replacement keywords have higher ticket values but longer sales cycles. Maintenance and tune-up keywords are cheaper but lower margin. Your budget should reflect which services actually make you money.

Seasonality

HVAC is one of the most seasonal industries in advertising. July and January are peak months where cost per click can spike 30-50%. Smart HVAC companies do not cut budget during shoulder seasons. That is when your cost per lead drops and you can book maintenance work that leads to replacement sales later.

Your Website and Landing Pages

This is where most HVAC companies waste money. You can have a perfect campaign, but if your landing page loads slow, has no phone number above the fold, or looks like it was built in 2012, you are paying for clicks that never convert. We have seen conversion rates double just by fixing the landing page. If you are not sure where you stand, reach out for a free audit.

What ROAS Should You Expect?

ROAS (Return on Ad Spend) measures how much revenue you get back for every dollar you spend on ads. For HVAC companies, a healthy ROAS on Google Ads typically falls between 5:1 and 10:1.

Here is what that looks like in real terms:

• Spend $3,000/month on Google Ads
• Generate 40 leads
• Close 12-16 jobs (30-40% close rate)
• Average ticket: $1,200 (mix of repairs and installs)
• Revenue: $14,400-$19,200
• ROAS: 4.8x to 6.4x

That does not factor in the lifetime value of a new customer. One AC installation lead can be worth $8,000-$15,000. A customer you keep for maintenance is worth multiples of that over five years.

If your ROAS is below 3:1, something is broken. It could be targeting, landing pages, or your sales process. If it is above 8:1, you should probably be spending more.

Google Local Services Ads: The HVAC Secret Weapon

If you are not running Google Local Services Ads (LSAs), you are leaving the easiest leads on the table. LSAs show up above regular search ads with your Google Guaranteed badge. You pay per lead, not per click, typically $25-50 per lead for HVAC.

The catch: you need to get Google Guaranteed, which means background checks and license verification. But once you are in, LSAs often deliver the best cost-per-lead of any channel for HVAC companies.

We recommend allocating 30-40% of your total Google budget to LSAs and the rest to traditional search campaigns.

How to Start Without Wasting Money

Here is the framework we use when onboarding a new HVAC client:

Month 1: Foundation ($1,500-2,000)

Start with your highest-intent keywords. “AC repair near me,” “furnace repair [city],” “emergency HVAC.” Set up conversion tracking properly from day one. If you skip this step, you are flying blind.

Month 2: Optimize and Expand ($2,000-3,000)

By now you have data. Kill the keywords that waste money, double down on what converts. Add negative keywords aggressively. Start testing ad copy variations. This is also when we layer in LSAs if the client qualifies.

Month 3: Scale What Works ($3,000-5,000)

With two months of data, you know your cost per lead and close rate. Now you can make smart decisions about scaling. Add installation keywords, expand geographic targeting, and launch remarketing campaigns to people who visited your site but did not call.

The Real Cost of Not Advertising

Here is what most HVAC owners miss: the cost of doing nothing is not zero. Every day you are not running ads, your competitors are picking up the calls that should be yours. In most Southern markets, the top 3-4 HVAC companies running Google Ads are splitting 70% of the search traffic.

A $3,000 monthly ad budget that generates $15,000-$20,000 in revenue is not an expense. It is your most predictable growth engine.
