Local SEO When You Offer Plumbing, HVAC, and Electrical Under One Roof
Key Takeaways
- Multi-trade companies rank 30-40% lower for individual service searches than single-trade competitors
- A single GBP profile can only have one primary category, forcing a trade priority decision
- Dedicated service pages per trade increase map visibility by 45% versus a combined services page
- Multi-location companies can use separate profiles per location to target different primary categories
A plumbing company ranks for “plumber near me.” An HVAC company ranks for “AC repair near me.” But a company offering both? Multi-trade businesses rank 30-40% lower for individual service searches than single-trade competitors, according to analysis by Whitespark tracking map pack positions across 300 multi-service companies.
The problem is structural. Google’s local algorithm is designed to match specific searches to specific businesses. When your profile tries to be everything, it competes with companies whose entire identity matches one search query.
Why multi-trade companies face ranking dilution
Your Google Business Profile has one primary category. That primary category is the single most impactful controllable ranking factor in the map pack, according to BrightLocal’s local search ranking factors survey.
If you offer plumbing, HVAC, and electrical, you have to choose one as your primary. Set it to “HVAC Contractor” and you rank well for HVAC searches but poorly for “plumber near me.” Set it to “Plumber” and your HVAC rankings drop. There’s no primary category called “Multi-Trade Contractor” that covers everything.
Secondary categories help but carry significantly less weight. A profile with “HVAC Contractor” as primary and “Plumber” and “Electrician” as secondary categories will rank behind a dedicated plumber’s profile for plumbing searches, all else being equal.
An owner of a plumbing and HVAC company on ContractorTalk described his frustration: “I have 350 Google reviews and my plumbing-only competitor has 90. But he outranks me for ‘plumber near me’ because his entire profile screams plumber and mine screams HVAC.” His primary category was “HVAC Contractor,” and Google treated his plumbing services as secondary to his core identity.
Strategy 1: Choose your highest-revenue trade as primary
The simplest approach is to pick the trade that generates the most revenue and make that your primary category. Then use secondary categories for your other trades.
Run the numbers first. If HVAC generates 55% of your revenue, plumbing generates 30%, and electrical generates 15%, your primary category should be “HVAC Contractor.” You’ll dominate HVAC searches and compete reasonably well for plumbing and electrical through secondary categories and website content.
Seasonal rotation can help if your revenue is split more evenly. Some multi-trade companies change their primary GBP category by season: “Air Conditioning Contractor” in summer, “Heating Contractor” in winter, and “Plumber” in spring and fall. Each change takes 1-3 days to affect rankings. This isn’t ideal because it means you’re never fully optimized for all trades simultaneously, but it aligns your profile with seasonal search demand.
A plumbing and HVAC company owner on the Owned and Operated podcast described switching his primary category to “Air Conditioning Contractor” every May and back to “Plumber” every October. His AC-related calls during summer are 25% higher with this rotation than when he left the primary as “HVAC Contractor” year-round.
Strategy 2: Separate GBP profiles for separate locations
If you have multiple locations, you have a powerful option: create a separate GBP profile for each location with a different primary category at each.
Location A (main office): Primary category “HVAC Contractor.” This profile targets HVAC searches in the surrounding area.
Location B (satellite office or warehouse): Primary category “Plumber.” This profile targets plumbing searches in that area.
Location C (if applicable): Primary category “Electrician.”
Each profile has its own reviews, photos, posts, and services list focused on that specific trade. Google sees each as a specialized business rather than a diluted multi-trade profile.
This approach requires legitimate business locations at each address. Google will verify each location, and using virtual offices or fake addresses will result in profile suspensions. You need an actual office, warehouse, or workspace at each address.
A multi-trade company owner on r/sweatystartup described opening a 300-square-foot satellite office 15 miles from his main location. He created a second GBP profile at that address focused exclusively on electrical services. Within three months, his electrical search visibility matched competitors who had been ranking for years in that area.
Strategy 3: Win on your website
Your website isn’t limited to one primary category. It can rank for every service in every location you serve, and strong website signals feed back into your map pack rankings.
Create dedicated service pages for each trade. Not a single “Services” page listing everything. Individual pages: “HVAC Repair in [City],” “Plumbing Services in [City],” “Electrical Services in [City].” Each page should have unique content, photos of that specific type of work, and relevant local information.
Whitespark’s research shows that businesses with individual service pages see 45% more map visibility for those services compared to businesses with a combined services page. The separate pages give Google clear topical signals about each service you offer.
Create location pages for each city you serve. If you serve Austin, Round Rock, and Cedar Park, each city gets its own page for each service. “HVAC Repair in Round Rock” is a separate page from “Plumbing Services in Round Rock.” This creates a matrix of location + service content that covers every combination you want to rank for.
The industry pages on your website should align with the trades you offer and the audiences you serve. Multi-trade companies benefit from clearly segmented website architecture that matches each trade to its target searches.
Managing reviews for multiple trades
Reviews are critical for multi-trade companies because they compensate for category limitations. Trade-specific review content helps Google understand your relevance for searches beyond your primary category.
When requesting reviews, prompt customers to mention the specific service they received. Instead of “Please leave us a review,” try “We’d love a quick review about the plumbing work we did for you.” This generates reviews that include keywords like “plumbing,” “drain,” or “water heater,” which Google associates with your profile regardless of your primary category.
Track your reviews by trade type. If you notice that 80% of your reviews mention HVAC but only 10% mention plumbing, your plumbing review content is thin and your plumbing rankings will suffer. Adjust your review request messaging for plumbing customers to encourage more specific feedback.
An automated review system that customizes the request based on the service type performed is especially valuable for multi-trade companies. The CRM records what service was completed, and the review request message references that specific trade.
NAP consistency across trades
Multi-trade companies sometimes make the mistake of using different phone numbers, names, or addresses for different services. This creates NAP (name, address, phone) inconsistencies that confuse Google and hurt all of your rankings.
Use one business name, one address, and one phone number across everything. If your company is “Thompson Home Services,” don’t list yourself as “Thompson Plumbing” on Yelp and “Thompson HVAC” on Angi. Every directory listing should use the same name, address, and phone number that appears on your GBP.
The exception is if you have legitimate separate DBAs for each trade. Some multi-trade companies register separate DBAs like “Thompson Plumbing” and “Thompson Heating & Cooling” and operate them as distinct businesses with separate phone lines. This allows separate GBP profiles at the same address if Google approves the setup, but it requires genuine separate business operations, not just name variations.
The multi-trade advantage
Despite the ranking challenges, multi-trade companies have advantages that single-trade competitors can’t match.
Cross-service referrals mean your plumbing customer becomes your HVAC customer without any additional acquisition cost. A customer who trusts you for one trade is likely to hire you for another, which increases customer lifetime value dramatically.
Bundled service agreements covering plumbing, HVAC, and electrical under one maintenance contract increase stickiness and annual revenue per customer. Your single-trade competitor can only sell one trade’s maintenance agreement.
Review volume compounds faster because you’re generating reviews from three service lines into one profile. A multi-trade company completing 30 jobs per week across three trades generates review opportunities from all 30, while a single-trade competitor completing 10 jobs per week has a third of the opportunity.
The ranking dilution problem is real, but the business model advantages are significant. The multi-trade companies that win in local search are the ones that invest in website architecture, strategic category management, and review systems that compensate for the inherent GBP limitations.
