When an HVAC contractor turns on Google Ads for duct sealing and Aeroseal, the first $3,000 often vanishes into one predictable sinkhole: broad match keywords. A term like "duct sealing" triggers searches for "duct sealing tape," "how to seal ductwork in a crawl space," and "duct sealant for cars." None of those searchers will ever hire a licensed technician. Without a trade-specific negative keyword strategy, every one of those clicks costs money and returns nothing.

The same account will run ads that lead to a general HVAC homepage. A homeowner searching "Aeroseal contractor near me" clicks, lands on a page about AC repair and furnace installs, and leaves within seconds. That click cost $22, and it delivered a Quality Score penalty that will inflate every future click in the campaign. These aren't hypotheticals. They're the standard autopsy findings on self-managed duct sealing accounts.

How Homeowners Search for Duct Sealing vs. What Your Ads Should Match

Search intent in this trade splits cleanly into three tiers. The top tier, the queries that produce signed contracts, are "Aeroseal company [city]," "duct leakage repair contractor," "aeroseal duct sealing near me," and "commercial duct sealing service." These searches carry transactional intent. The searcher has already decided the problem is real, and they want a professional to fix it.

The middle tier includes information-gathering queries like "Aeroseal cost per square foot," "is duct sealing worth it," and "how long does aeroseal last." These convert anywhere from 3% to 12% if the landing page answers the question and pushes a clear estimate request. They are worth targeting with tightly controlled budgets, not full bid aggression.

The bottom tier is where self-managed budgets die. "Duct sealing products," "aeroseal training," "duct mastic vs tape," "how to become an aeroseal dealer." These searches look enough like service queries that broad match keeps serving ads for them. The click-through rate plummets. Quality Score drops. Cost per lead triples.

Device and time-of-day patterns also separate profitable accounts from bleeding ones. Homeowners with high electric bills search evenings and weekends from a mobile phone. Facility managers and property owners search during business hours from a desktop. A campaign that bids identically around the clock and across devices will miss those conversion peaks.

Building a Campaign That Separates High-Value Leads from Tire-Kickers

A correctly built Google Search campaign for duct sealing and Aeroseal controls every variable at the campaign, ad group, and keyword level

Campaign and Ad Group Structure

Campaigns get segmented by service type and intent tier, not by geographic radius alone. One campaign targets Aeroseal-specific searches with high commercial intent. Another campaign targets general duct sealing and duct leakage repair terms. A third campaign may target commercial property managers, using different language and dedicated landing pages.

Ad groups inside each campaign isolate a single service theme: "Aeroseal Installation," "Duct Leak Testing," "Commercial Duct Sealing," "Residential Energy Loss." When a keyword and ad share one tightly defined theme, Ad Relevance scores stay high, and Quality Score rewards the account with lower CPCs.

Geographic targeting uses radius bidding with bid adjustments that increase for the most profitable ZIP codes. If the contractor serves three counties but 70% of booked jobs come from two ZIP clusters, the account structure reflects that.

The Match Type Trap

Poorly chosen match types are the leading cause of wasted spend in this category. Exact match keywords protect high-intent terms like [Aeroseal contractor near me] and [duct leakage repair]. Phrase match captures variations that still hold intent, like "Aeroseal duct sealing" and "duct sealing cost." Broad match, if used at all, sits inside a tightly watched campaign with a massive negative keyword list generating daily review. Without that discipline, broad match on "duct sealing" produces a flood of irrelevant clicks from product seekers, DIY researchers, and job hunters.

Negative Keywords That Stop the Bleed

A duct sealing and Aeroseal account must block specific search term categories from day one. The list includes:

• DIY and product terms: "tape," "mastic," "sealant," "aluminum tape," "foam seal," "duct sealant home depot," "Lowe's," "Amazon"
• How-to and informational intent: "how to seal ductwork," "diy duct sealing," "what is Aeroseal," "duct sealing guide"
• Jobs and certification: "jobs," "hiring," "salary," "training," "certification," "become an Aeroseal dealer"
• Competitor brands that the contractor cannot service, including specific manufacturers if the business only installs Aeroseal
• Out-of-area searches: city names and ZIP codes outside the service area, added as exact negatives weekly

Every week without adding new negatives is a week of budget spent on clicks that were never going to become a lead.

Ad Assets That Lift Click-Through Rate and Ad Rank

Ad assets directly influence expected CTR and Ad Rank for duct sealing ads. The configuration that works includes:

• Call assets using a Google forwarding number so every ad click that becomes a phone call is tracked as a conversion
• Location assets that display the verified business address and a map pin, signaling legitimacy to searchers comparing multiple contractors
• Sitelink assets to specific service pages: "Aeroseal System," "Duct Leakage Test," "Commercial Duct Sealing," "Residential Pricing and Savings"
• Callout assets that differentiate: "Licensed and Insured," "Certified Aeroseal Dealer," "Free Duct Leakage Assessment," "Energy Star Partner"
• Structured snippet assets on "Services" with values like "Aeroseal Application, Duct Sealing, Leak Testing, Energy Audits"
• Price assets where fixed fees exist, such as a standard duct leakage test cost, so homeowners self-qualify before they click

Responsive Search Ads That Convert, Not Just Fill Space

A weak RSA pins two headlines both reading "Aeroseal Duct Sealing" and a description that says "We seal ducts. Call us." That ad earns a below-average expected CTR, and Quality Score penalizes every impression.

SBS builds RSAs with 12 to 15 headlines rotating combinations of the core service, the location, a trust signal, and a call to action. Examples: "Certified Aeroseal Installer | Schedule a Test," "Duct Sealing in [City] | Stop Losing Cooled Air," "Free Leakage Assessment | Commercial and Residential." Descriptions speak directly to the pain point: higher energy bills, uneven room temperatures, dust and allergen circulation. Headline pinning is minimal. The machine learning gets enough variation to find winning combinations without being forced into repetitive ad copy.

Quality Score in Duct Sealing: Why Relevance Wins

The Quality Score triad hits this trade with predictable force. Expected click-through rate surges when an ad matches exactly what the user typed. Someone searching "Aeroseal cost" sees an ad with the headline "Aeroseal Duct Sealing Cost | Transparent Pricing" and clicks. That ad relevance signal carries over to the campaign's historical CTR metrics.

Landing page experience in duct sealing is a friction point for self-managed accounts. When a click on "commercial duct sealing" lands on a page that discusses residential AC repair, Google records a poor landing page experience. SBS builds or aligns service-specific landing pages with fast load times, clear calls-to-action, and content that matches the ad's promise. That lifts the third Quality Score component and lowers the CPC the account has to pay to maintain position.

Conversion Tracking: The Difference Between Data and Darkness

Running a duct sealing campaign without conversion tracking is equivalent to working blind. The conversions that matter are:

• Phone calls generated directly from the ad using a Google forwarding number
• Phone calls from the landing page, tracked with a call tracking number swapped dynamically
• Form submissions for an estimate or duct leakage assessment
• Click-to-call actions on mobile devices

Without these conversion events feeding back into Google Ads, Smart Bidding strategies like Target CPA or Maximize Conversions cannot function. Self-managed accounts often run Target CPA on two conversions per month and get erratic, budget-wasting bid decisions. SBS ensures at least 30 conversions in a 30-day window before handing bid strategy to automation.

Local Service Ads and Your Search Strategy: Competitor or Partner?

HVAC contractors qualify for Local Service Ads with the Google Guaranteed badge. LSAs appear above standard search ads for queries like "duct sealing company near me." They charge per lead rather than per click. For duct sealing and Aeroseal, LSAs can complement search campaigns but also compete for the same screen real estate.

If an LSA profile is active and the search campaign bids on the same head terms, the LSA will often intercept the click. The contractor pays for a lead whether the lead is qualified or not. Search ads, meanwhile, allow for precision targeting and message control that LSAs do not. The right allocation for this trade usually puts LSAs on branded service terms like "Aeroseal contractor" and highly local queries, while search campaigns handle broader duct sealing terms, commercial searches, and research-phase queries that LSAs may not serve. SBS manages the budget split so the two channels work together instead of bidding against each other.

The Anatomy of a High-Performance Duct Sealing Account

Top-performing accounts in this trade are distinguishable in five seconds. The account structure shows campaigns segmented by service, not one campaign housing every keyword. The negative keyword list grows weekly and contains 300 to 800 terms specific to this trade. Smart Bidding is active and uses a Target CPA informed by real conversion volume, not a guess. Ad schedules are calibrated to the hours when phones actually ring: weekday mornings for commercial property managers, evenings and weekends for homeowners.

A bleeding account shows the opposite. A single campaign with all keywords in one ad group. Broad match enabled on every keyword. No negatives added in months. Ads point to the homepage. Conversion tracking is absent or misconfigured. Maximize Clicks is the bid strategy, and the account is spending $800 a month on traffic that will never produce a lead.

Mistakes That Turn a $5,000 Budget into a $1,200 Monthly Loss

The same mistakes recur across self-managed duct sealing accounts.

• Broad match on "duct sealing" without negatives. This single keyword regularly consumes $1,200 a month in unqualified traffic from tape, DIY, and product searches.
• Ads leading to the main HVAC homepage. A searcher looking for Aeroseal leaves because the page does not mention the technology by name, killing conversion rate and Quality Score.
• An account set up three years ago and never audited. Ad copy grows stale, ad assets fall out of date, and Quality Score drifts downward as competitors refine their targeting.
• Target CPA or Maximize Conversions running on insufficient conversion data. The algorithm makes aggressive bid decisions based on three conversions in a month, inflating CPCs without delivering leads.
• Location targeting set to "presence or interest" instead of "presence" for local service ads. The account serves ads to people searching for duct sealing in distant cities because they once showed interest, burning budget on unserviceable geography.
• Treating "Aeroseal" as a generic keyword. Without phrase or exact match controls and a negative keyword list that excludes dealer searches, the term triggers clicks from someone in another state wanting to buy equipment or find a training program.

Why a Google Partner Builds a Lower Cost Per Lead

SBS holds a certified Google Partner badge because the account performance across our managed portfolio consistently meets Google's thresholds for optimization, spend, and client retention. That partnership gives SBS access to dedicated Google account support, beta features not available to self-managed accounts, and category-level benchmarks that show exactly what a well-run duct sealing and Aeroseal campaign should deliver.

A business owner managing their own account pays for the learning curve with live budget. They lack the benchmarks to know whether a $45 cost per lead is strong or three times what it should be. They touch the account only when results are visibly bad, so opportunities to improve Quality Score and reduce wasted spend go unnoticed for months.

SBS manages the full stack for duct sealing and Aeroseal contractors:

• Full account audit against HVAC industry performance data
• Campaign architecture that segments by service, intent tier, and geography
• Keyword strategy built on trade-specific search intent and match type allocation
• Negative keyword management with weekly audits and additions
• RSA and ad copy development with continuous testing against conversion data
• Ad asset configuration to maximize Ad Rank without sacrificing CTR
• Landing page alignment so every click lands on a page that reinforces the ad's promise
• Conversion tracking setup with call and form tracking through Google forwarding numbers
• Smart Bidding calibration once conversion volume is sufficient to train the algorithm
• Ongoing optimization cycles that touch the account multiple times per week, not once per quarter

Google Ads in a competitive trade like HVAC duct sealing requires rigorous management to deliver a profitable cost per lead. The gap between a professionally managed account and a self-managed one is not measured in clicks. It is measured in the fact that one account generates booked estimates for $40, and the other spends $1,200 a month on duct tape searches.
