Local advertising for plumbers and HVAC: own your service radius

Trades win jobs inside a drivable radius. How plumbers and HVAC companies keep their name on those exact streets with car advertising — from $500/month on neighbours' cars.

A plumber's business lives inside a radius: the streets close enough that a truck roll makes money. Everything outside it is someone else's customer; everything inside it is a homeowner who will, sooner or later, have a burst pipe, a dead furnace, or a hot-water tank on its last legs. The marketing question for trades isn't 'how do I reach more people' — it's 'how do I make sure the people inside my radius already know my name on the day their emergency happens.' Lunar (lunarcar.me) answers that literally: your brand rides on everyday cars that live and drive inside your service area, from $500 a month.

Trades are bought in emergencies — and emergencies are won earlier

Nobody comparison-shops with water coming through the ceiling. They call the name they know: the company a neighbour mentioned, the logo they've seen around, the first familiar result in a panicked search. That means the real competition happened weeks before the emergency — in whether your name was already planted. Search ads catch the moment, but they're an auction against every competitor at the single most expensive instant; presence advertising plants the name cheaply for months beforehand, so that when the moment comes, you're the incumbent. The two work best together: presence makes the emergency click cheaper because the searcher recognizes you.

Why cars fit the trades better than billboards

• Radius match: you set a target zone around your shop, and Lunar matches drivers whose declared driving zones overlap it — impressions land inside truck-roll range, not across the whole metro like a highway board.
• Neighbourhood credibility: a trade's best proof is being 'the company everyone around here uses.' Your sticker on residents' cars — sometimes literal past customers — reads as exactly that.
• Always-on, including parked: a car parked overnight on a residential street is a small yard sign the whole block passes on the morning walk. A parked car keeps advertising when a moving one stops.
• Cost sanity: plans start at $500/month for a few cars, scaling to ~16 with Full Moon — priced for a local service business, not a regional brand campaign.

The math against one furnace job

An HVAC install runs four figures; even a water-heater swap clears a thousand dollars most places. A drain-cleaning customer becomes a repipe customer becomes a referral. Against those tickets, $500 a month of neighbourhood presence pays for itself with roughly one incremental job a quarter — and unlike a lead-gen service that charges per call and sells the same lead to three competitors, presence is exclusively yours and compounds: the same streets see the same name all year. Estimated impressions are reported honestly on your dashboard — estimates, the same reach logic as any out-of-home medium — alongside the verified miles behind them.

Make the sticker do trade-specific work

A circle decal is small, so make every element earn its spot: company name, trade ('Plumbing & Heating' beats a vague slogan), phone number big enough to read at a stoplight, and your license or 'licensed & insured' line if your regulator expects it. Skip the mascot backstory. The design brief that works for trades is the one a homeowner can act on from memory an hour later — name, what you do, how to call. Artwork is prepared from your brand assets as part of the plan; the print, ship, and install verification loop is handled by the marketplace, photos and weekly odometer checks included, as covered in how Lunar verifies real driving.

Recruit the vans' little siblings

Your wrapped vans already advertise — when they're driving, which is when they're billing. Lunar puts the off-hours version of that presence on cars that are always in the neighbourhood: happy customers, staff members' personal vehicles, the retired couple two doors down who'll gladly back a company that fixed their furnace at 11pm. Drivers choose brands they're willing to carry and get paid from the plan you're already running — so a customer who loved your service becomes a paid, verified, rolling referral. Mention it on the fridge magnet you leave behind; the marketplace handles the rest.

Seasonal timing for trades

HVAC demand spikes with the first heat wave and the first cold snap; plumbing peaks with freeze events and the fall rain. Presence advertising's job is to be established before those spikes — a 3, 6, or 12-month phase running through the shoulder season means your name is already planted when the whole neighbourhood's furnaces struggle on the same November morning. The businesses that win those weeks aren't the ones who started advertising that day.
