TL;DR: Search ads may reach people who need an HVAC repair now. Facebook Ads may be more useful for a maintenance offer to past customers or a seasonal campaign. Get the required permission before using customer data. Count booked jobs and profit after ad costs for each test.
Check whether the proposal charges a management fee in addition to Meta spend and whether that fee depends on results. Judge the proposal on the scope of work, the tracking that comes with it, the booked-job economics, and how you get out of the contract.
Our own angle, stated up front: Xomer sells a managed website and visibility service and does not manage Facebook Ads for anyone. That tilts this comparison toward things you own. Read it with that in mind.
Search expresses emergency intent more directly
When a homeowner's air conditioner dies in August, they reach for whatever is fastest. Search, maps, an AI assistant, a neighbor's recommendation, a number already saved in their phone. Search has one practical advantage in that moment: the words they type say what they need right now, which is a stronger signal than an interest category. Your ad still has to win the click.
A Facebook ad can reach someone who has not searched for HVAC help. An interest setting can't tell you whose AC is broken today. Compare the two channels on qualified calls and booked jobs, and pull your own call log before you decide where the emergency work is really coming from.
Use search to test explicit emergency demand and social to test defined audiences or offers. Let attribution and booked-job economics decide the role of each.
Emergency repairs are the cleanest search test, because the intent is written into the query. Replacement customers may take longer to decide. Record the quote requests and time to booking in your own job log. If you can only fund one channel this year, split your own booked jobs into emergency and replacement first, then fund whichever one pays you better. Our Google Ads for HVAC review covers the search-side math.
One Facebook test: eligible people who already know you
For this comparison, separate customer-list campaigns, site-visitor campaigns, and prospecting. Check the data use and permission requirements for the targeting method you choose. Prospecting does not necessarily involve uploading a customer list.
A maintenance-agreement offer is the natural first test against your customer list. These are people who have already let you into their house, so the ad has less work to do. Upload that list only with the permission you are required to have and inside Meta's terms. Recognition helps the offer land. The offer still has to be worth booking.
Retargeting reaches some of the people who already visited your site. Browser tracking limits, permissions and audience eligibility can affect whom you reach. Compare actual delivery with the estimate in your account. Before comparing it with broad targeting, set a spend cap, a window that allows for your sales lag, a decision threshold and stop rules. Keep the test within your booking capacity. Compare booked jobs under similar conditions, and if only a handful come in, run it longer before you judge it.
Pick the window for a maintenance campaign from your own booking and renewal records. If you run an HVAC company in Cincinnati, look at when last year's tune-up customers booked and when the schedule had room. Compare the campaign with similar customers or periods, and note the weather and open appointments at the time.
Compare pre-season and peak timing
Pre-season awareness is the second thing Facebook is worth testing on, and the whole case rests on timing. Compare calls and bookings with weather and campaign dates in your own records. Test whether an earlier maintenance offer produces useful work before demand or capacity changes. Do not assume that customers in a busy week all arrive through search.
A pre-season "schedule your AC tune-up" campaign is one way to test it. Compare it with a period or eligible audience without spend, while recording weather, capacity, and other campaigns. Weather moves HVAC demand, so compare weeks with similar weather.
A campaign can fail on timing, audience, offer, creative, tracking, or how fast your office picks up the phone, and the platform report will not tell you which. To rule out timing, an HVAC company in Virginia Beach can pick a test window from last year's booking calendar, then make sure this year's crew can take the calls on those dates.
The math, honestly
The cost question needs two rows, not a single reported cost per lead. In the first row put cold prospecting: media, agency fee, creative, valid calls, booked replacements or repairs, and gross profit after the crew and parts. In the second put customer-list or site-visitor campaigns, with the same columns. A repeat customer who would have booked anyway can make the warm row look artificially cheap. Ask callers what prompted the booking and compare with a similar period or audience that did not see the campaign.
Before uploading customer details, check the consent and permitted use against Meta's Custom Audience terms. If you can't tell campaign work from normal renewals, don't count Meta's attributed conversions as extra profit.
Price the whole proposal, not the ad spend on its own. Management fee, creative production, tracking setup, and the media budget all come out of the same pot of money. Once you have that total, ask what the same amount would do in a channel you are already running.
Cold prospecting needs its own line in the report. Split broad targeting from your defined audiences, and track qualified calls, booked jobs and gross profit on each one separately. Cold audiences deserve a real test before you write them off, because the answer moves a lot between markets.
Warm audiences need the same arithmetic carried all the way to the end. How many consented contacts you uploaded, how many Meta matched and delivered to, how many valid leads came back, how many signed an agreement, what those agreements cost you to service, and what is left over. Four or five agreements sounds like a win until you put the management fee next to it. Meta's advertising documentation explains what the audience tools do, and says nothing about what HVAC accounts get out of them.
Test the pattern separately in other home service trades
Plumbers, electricians and roofers carry the same mix you do: urgent work, planned work, repeat customers, maintenance. The tidy split where emergencies go to search and relationships go to social rarely survives a look at the actual job list, so segment your own demand and check where each type came in from. Our broader home-service Facebook Ads framework runs the same test across those trades.
Facebook is a capable ad platform. Reach and audience definition can matter to emergency work too; the question is whether the campaign reaches a customer who needs your service at a cost the job can support. If I had one budget and an HVAC company with no maintenance list yet, I would put it into search first and come back to social once I had a customer list I could use for a permitted maintenance campaign.
What to verify before scaling an HVAC campaign
Get the plumbing right before you scale anything. The website has to convert, the lead tracking has to fire, someone has to answer the phone inside a couple of rings, and your privacy disclosures and audience consent have to hold up. Decent search visibility and a complete Google Business Profile help, though you do not need either one finished to run a valid social test.
A customer-list campaign for maintenance plans or tune-ups is a reasonable first Facebook test once consent and tracking are in place. Give it its own budget and its own report so you can see what it did on its own. An Indianapolis HVAC business should order its channels from its own demand, tracking, crew capacity and margins.
Look back before you test. A Tucson HVAC contractor with a year of calls and bookings can see which months brought emergency repairs and which brought planned maintenance. Ask new customers how they found you, and run any maintenance campaign to consented customers separately from emergency work, so each has its own results.
Facebook Ads are worth a small, capped HVAC test when you have a defined, consented audience and a real offer for them. Search is usually the better test for emergency intent. Keep whichever channel you can tie to booked jobs and gross profit in your own numbers, and stop paying for the one you cannot.
If the HVAC landing page hides the service area or contact route, request a free written website and AI visibility audit. The audit reads your pages, your business listings and what Google and AI assistants say about you, then tells you what to fix first. Existing-site implementation is scoped separately.
