Google Ads for HVAC Companies: The Account Structure That Books Jobs

HVAC is the trade where Google Ads is hardest to run well. Demand arrives in spikes nobody controls (the first 95-degree week, the first hard frost), every competitor's budget spikes with it, and the cost per click climbs exactly when you need the clicks most. LocaliQ's 2026 benchmarks put the Home & Home Improvement average at $8.33 a click and $90.92 a lead; an "ac repair near me" click in a southern metro in July can run several times that.

The HVAC companies that make Google Ads pay are not bidding harder. They are structured differently. Here is the account structure I build for HVAC companies, the keywords and negatives that go in it, how the budget should move with the weather, and the mistakes that burn budget in the accounts I take over.

Three campaigns, because there are three buyers

An HVAC company sells to three completely different people, and one campaign cannot serve them all:

• The emergency buyer (AC not cooling, no heat) decides in minutes, calls rather than fills forms, and does not compare prices. About half the budget in season.
• The replacement buyer (new AC cost, heat pump installation) shops for weeks, wants a price range and financing, and converts on a quote form as often as a call. Around a third of the budget, heaviest in the shoulder months when they research.
• The maintenance buyer (AC tune-up, furnace tune-up, maintenance plan) is the cheapest click in the account and the most valuable long term, because a plan member calls you first for the next repair and the eventual replacement. Ten to fifteen percent of budget, run in spring and fall.

Separate campaigns give each buyer its own budget, schedule, landing page and bid strategy. That separation is the whole structure; everything below hangs off it. How maintenance agreements flatten the seasonal swing is the backbone of my HVAC marketing plan.

Keywords: match types and the negatives that matter

Google defaults new keywords to broad match, and its keyword matching documentation says broad match can show your ad for searches related to your keyword. For "hvac", related means "hvac salary", "hvac school near me", "hvac technician jobs" and "how to recharge home ac". Run the money terms on phrase and exact match, and load the negatives before launch.

• Emergency campaign: ac repair near me, ac not cooling, emergency ac repair, ac repair [city], furnace repair, heater not working, no heat, 24 hour hvac.
• Replacement campaign: ac replacement cost, new ac unit cost, central air installation, heat pump installation, furnace replacement, hvac financing.
• Maintenance campaign: ac tune up, furnace tune up, hvac maintenance plan, hvac service plan.

The HVAC negative keyword list I start every account with: salary, jobs, hiring, technician, school, training, certification, course, DIY, how to, parts, filter, filters, capacitor, thermostat manual, reset, amazon, home depot, lowes, window unit, portable, car, auto, rv. Add manufacturer names only for brands you do not service. Then read the search terms report weekly during the rushes; in a heat wave, new junk variations appear daily.

Budgets that move with the weather

Google lets you change a daily budget at any time, and an HVAC account should. Raise the emergency campaign the week before the forecast turns, not the week after, because the auction takes days to settle at a new budget. The rough calendar: cooling emergency budget up from late spring through the end of summer; heating emergency up from the first frost; replacement steady all year with a lift in the spring and fall shoulder months; maintenance only March to May and September to November. Pause what is out of season rather than letting it trickle. A furnace tune-up ad in July buys nothing.

Weather can be automated with budget rules, but the simple version works: a ten-minute Monday check of the ten-day forecast against the three budgets.

Local Services Ads for HVAC: run them first

HVAC is an eligible trade for Local Services Ads, which Google's getting-started guide walks through: the Google Guaranteed badge at the very top of the page, a charge per lead rather than per click, and Google checking your licence and insurance first. For emergency repair, LSAs usually beat Search on cost per lead, and you can dispute leads that were not real jobs.

They do not cover replacement research well. Nobody making a $12,000 decision calls the first badge they see; they read, compare and come back. That is exactly what the Search replacement campaign is for. The full comparison is in Local Services Ads vs Google Ads.

Landing pages and tracking

Three campaigns, three landing pages. The emergency page has the phone number and a tap-to-call button above the fold, today's hours, "technician in your area today" and reviews. The replacement page has price ranges, financing, rebates and a short quote form. The maintenance page has the plan price, what is included and a sign-up. Google's Quality Score rewards that relevance with cheaper clicks, so the homepage-for-everything shortcut costs twice: a bounced visitor and a higher price on every click after.

Count as conversions only the things that are money: calls over 60 seconds through call reporting, quote forms and plan sign-ups. Smart Bidding chases whatever you call a conversion. Check the landing pages with my free 30-second audit tool; a six-second mobile load loses the emergency buyer before the call button appears.

The HVAC Google Ads mistakes I see most

• One campaign for everything. The emergency buyer and the replacement buyer share a budget, and the replacement research clicks starve the emergency calls in July.
• Broad match with no negatives. Typically 20 to 30 percent of spend in the accounts I audit.
• Every click lands on the homepage. Covered above; it costs twice.
• Ads running at 2am with nobody answering. Either staff the phone or schedule the ads to the hours you pick up.
• Bidding on brands you do not carry. "Carrier ac repair" clicks from people who want a Carrier dealer.
• Tune-up ads left running in July. Nobody books a furnace tune-up in a heat wave.
• Measuring clicks instead of booked jobs. The account looks healthy right up until the owner checks the bank.
• No remarketing on replacement buyers. They visit three or four times before they ask for a quote. A small remarketing list on the replacement page is the cheapest conversion in the account.
• Performance Max switched on with twenty conversions a month. It needs data to learn from; without it, it buys the cheapest clicks it can find.

What it costs, and who should run it

In my experience a single-location HVAC company needs $1,500 to $4,000 a month of media budget in the cooling and heating rushes for the account to learn, and can drop to a fraction of that in the shoulder months with the replacement campaign kept steady. Below about $500 a month the clicks are too few to optimise. Management, if outsourced, is a flat fee, a percentage of spend or a hybrid; the three models and who should not buy management at all are on my Google Ads management page, and the contractor-specific version of the service is Google Ads for contractors.

A Search account I run on this structure has produced 98.3K clicks and 15.8K conversions; the dashboard is on that page. Judge your own account the same way: cost per booked job by campaign, with the maintenance plan sign-ups valued for the repair and replacement calls they bring later.

Where this fits

Google Ads is the fastest channel an HVAC company has and the first one to stop when the budget does. It belongs alongside the compounding work: local SEO for HVAC for the Map Pack, the keyword and content detail in the HVAC SEO guide, and Meta Ads for selling replacements before the heat wave rather than during it. The trade-agnostic version of this post, with the four budget leaks every contractor account has, is PPC for contractors. If you would rather have the SEO side done for you, that is SEO for HVAC companies.
