Heating and cooling is a demand business with a weather problem. Search volume for emergency repair can multiply during the first hard freeze or the first serious heat wave, then collapse for weeks, and a paid search program that spends evenly through the year is fighting its own market. HVAC PPC done well is really about being present and responsive during the hours and days that matter, and being quiet the rest of the time. This page sets out how the seasonality changes campaign design, which conversions are worth counting for a contractor, what moves an agency's fee, and how to check a candidate against evidence you can verify yourself.
Seasonality is the whole design problem
In most of the country, HVAC demand arrives in two spikes separated by long quiet stretches, and the emergency repair searches that convert best are concentrated in a handful of extreme weather days. Two consequences follow. First, budgets should be allowed to flex rather than being capped at a flat daily figure that leaves you invisible on precisely the day everyone is searching. Set a plan for what the account does during a heat wave and agree it before the heat wave, not during it. Second, the off-season is not dead time; it is when maintenance plans, system replacement and financing searches are cheapest and least contested, and when a contractor building a recurring service base has a real advantage. Ad scheduling deserves attention that most accounts never give it: if your dispatch answers around the clock, evening and weekend hours for emergency terms are among the most valuable in the account, and if it does not, paying for those clicks is buying voicemail.
Which conversions actually mean anything
For a contractor, the meaningful outcome is a booked job, and the chain to it runs through a phone call. Counting form fills and clicks measures the smallest and least valuable part of the response. Every campaign needs its own tracking number, and call recording, where your state permits it, is what makes a call count honest. Agree with the agency what a qualified call is, typically a new customer, inside your service area, about a service you sell, and have reporting show qualified calls rather than total calls. Then push one step further and get booked jobs back from your dispatch software into the same report, because the gap between calls and bookings is usually a dispatch problem rather than a marketing one and you want to see it. Contractors who also invest in organic visibility for the same terms tend to find their paid cost per booked job falls over a season as branded searches grow, which is the argument for planning an HVAC SEO program alongside the ad budget rather than instead of it.
Structure, geography and where budgets leak
Three leaks account for most wasted HVAC spend. The first is geography: accounts left targeting people interested in a location rather than people physically in it will pay for clicks well outside any van's reach, and Google documents both settings clearly enough that there is no excuse for getting it wrong. The second is intent mixing: repair, replacement, maintenance plans and commercial work have different values and different close rates, and running them in one campaign lets the cheapest clicks absorb the budget. The third is search term drift, where broad matching pulls in do-it-yourself instructions, parts shopping, manufacturer warranty queries and job seekers. The fix in every case is unglamorous weekly maintenance: read the search terms report, add negatives, check the location settings have not been altered, and confirm the ad schedule still matches when you can actually answer. Ask a candidate agency how often it does exactly that, then ask to see the change history from an account it runs.
Fees, and how to vet an HVAC agency
Management fees come as a flat monthly figure, a share of media spend, or a hybrid with a floor. Because HVAC budgets swing hard with the weather, a pure share of spend produces a fee that collapses in the shoulder season, exactly when the account needs building work done. A flat fee with a stated hours commitment usually serves a contractor better. What moves the price is the number of service areas, whether replacement and commercial lines are managed separately, whether landing pages are produced, and whether Local Services Ads are managed alongside standard campaigns, since that product has its own verification and charges per lead rather than per click. To vet a candidate, ask for two contractor accounts at your scale and what changed in the first ninety days, ask what it would switch off in your account today, and insist the Google Ads account and the call tracking numbers belong to you. A contractor who cannot take the phone numbers with them has bought a lease, not an asset.
Questions people ask about hvac ppc
How much should an HVAC contractor budget for paid search?
Enough to be present on peak demand days, which usually means a flexible budget rather than a flat one. Work backwards from your average job value and close rate to a cost per booked job you can afford, then set the budget so the account can spend into a heat wave without hitting a cap.
Should I pause ads in the shoulder season?
Rarely pause entirely. Shift the emphasis instead, from emergency repair terms toward maintenance plans, tune-ups and system replacement, which are cheaper and less contested then. Going completely dark also loses the account's recent performance data going into the next peak.
Are Local Services Ads worth it for HVAC?
Often yes, because they charge per lead and appear above standard ads, but they require verification including background and license checks. Run them with separate tracking alongside search campaigns and compare cost per booked job before shifting budget between the two.
What is the fastest way to cut wasted spend?
Read the search terms report and the location settings this week. Those two checks find most of the waste in most contractor accounts, usually in the form of out-of-area clicks and do-it-yourself queries that no negative list has ever excluded.
