How to Build an HVAC Contractor Lead List by Zip Code
A step-by-step way to pull HVAC contractors by zip code from Google Places and Yelp, keep only the fields that matter, and dedupe the list before it ever touches a spreadsheet or CRM.
Quick Answer: To build an HVAC contractor lead list by zip code, pull business records from Google Places and Yelp Fusion, keep name, phone, address, site, and rating, cross-check license status separately, then dedupe by phone number before loading the list into a CRM.
You need a list of HVAC contractors in a handful of zip codes for a supplier deal, a franchise rollout, or a B2B offer aimed at the trade, and the free tools in front of you are Google, Yelp, and a spreadsheet. An afternoon of copy-pasting gets you a rough list. A second afternoon, three weeks later, gets you a stale one, because contractors close, rebrand, and get bought out faster than a spreadsheet updates itself.
What is an HVAC contractor lead list?
An HVAC contractor lead list is a structured set of business records — name, phone, address, website, and rating, at minimum — for heating and cooling contractors operating in a defined geography. It is the raw material for cold outreach, territory mapping, or a supplier partnership pitch, not the pitch itself.
The list is only as useful as its freshness and its fields. A hundred rows with dead phone numbers is worse than twenty rows you can actually call.
Where can you find HVAC contractor data by zip code?
Two official sources cover most of the ground. Google Places returns any business with a Google Business Profile, which is close to universal for contractors who want to be found. Yelp Fusion covers businesses that have claimed or been added to a Yelp profile, which skews toward companies that actively manage their online reputation.
Neither source verifies a contractor's license. For that, your state's contractor licensing board is the authoritative record, and it is worth a separate lookup before you treat a name on your list as vetted.
The Google Places API documentation lists exactly which fields a basic search returns and which ones require a separate Place Details call — worth reading before you assume a field is included by default.
What fields does a usable HVAC lead list need?
Keep the list narrow. Every extra field is another thing that goes stale.
| Field | Why it matters | Example |
|---|---|---|
| Business name | Matching across sources and avoiding duplicate outreach | Coastal Air & Heat LLC |
| Phone number | The most stable identifier for deduping | (555) 401-2290 |
| Address | Confirms the contractor actually serves the target zip code | 118 Depot St, Suite B |
| Website | Source for a decision-maker's name or a contact form | coastalairheat.example |
| Rating and review count | Rough signal of how active and trusted the business is | 4.6 stars |
How do you turn one zip code into a full service territory?
A single five-digit zip code rarely maps to a full sales territory. Dense urban codes can return a workable list on their own; rural codes usually need to be stacked.
- Pull the target zip code first and count how many contractors come back.
- If the count is thin, add the two or three adjacent zip codes rather than switching methods.
- Decide whether you need postal-code precision (matches how contractors self-report their service area) or a radius search (matches how far a technician will actually drive).
- Tag each record with the zip code it came from so you can measure response rate by area later.
- Re-run the same zip cluster on a schedule instead of building a new list from scratch each time.
How do you avoid duplicate or outdated HVAC listings?
Duplicates come from two places: the same contractor showing up in both Google and Yelp results, and multi-location franchises listing each branch separately under a near-identical name.
- Normalize every phone number to digits only before comparing rows — formatting differences hide obvious duplicates.
- Match on phone number first, then fall back to address for franchise locations that share a name.
- Flag any listing with no reviews in the last year as likely outdated and verify before you contact it.
- Re-check a list older than 90 days before running a new outreach pass against it.
When does building this list by hand stop being worth it?
Building this by hand works fine for one zip code and one afternoon. It stops working once you need several trades, several zip codes, and a list you can refresh monthly without redoing the manual pull every time.
That is the point where a tool built specifically for zip-code-plus-trade search, like ExtractData, saves the hours the manual method costs on the second and third pass. See what each plan includes on the pricing page before deciding whether the manual route or a paid plan fits your list size.
What do you do with the list once it is built?
A list is not pipeline until someone acts on it. Segment by rating and review count first — a four-star contractor with steady reviews is a different conversation than a one-star listing with no recent activity.
From there, the next steps are writing a cold email that actually gets replies and deciding how to turn the list into a working sales pipeline rather than a spreadsheet nobody opens again. If restaurants are also part of your territory mix, the same zip-code method applies — see how to find restaurants by zip code for that version.
The bottom line
The most common objection to paying for any of this is that Google and Yelp are free to search by hand. That is true for one zip code on one afternoon. The real cost shows up on the second pass — re-pulling the list, re-deduping it, and cross-checking Yelp against Google for the same contractor a second time, every time the list goes stale.
Start on the free plan, run one zip code and one trade, and compare the result against what you would get searching by hand in the same ten minutes. Create a free account and search your first zip code today.
Frequently asked questions
What information does a Google Places search return for an HVAC contractor?
A Google Places search returns the business name, address, phone number, website, and star rating. It does not return license status, years in business, or an email address, so those require a separate licensing-board lookup or an enrichment step.
Is Yelp Fusion data different from Google Places data for HVAC contractors?
Yes. Yelp Fusion covers businesses that have claimed or been added to a Yelp profile, which skews toward companies that actively manage their online reputation, while Google Places covers nearly any business with a Google Business Profile, so the two lists usually only partially overlap.
How many zip codes should one HVAC prospecting list cover?
It depends on population density. A single dense urban zip code can return a workable list on its own, while rural zip codes usually need to be stacked in a small cluster of adjacent codes to reach a usable size.
Do I need an EPA certification to build a contact list of HVAC contractors?
No. EPA Section 608 certification applies to the technicians who handle refrigerant, not to a marketer building a contact list, but knowing the requirement exists helps you understand what a contractor prospect actually cares about when you reach out.
What is the fastest way to remove duplicate HVAC contractors from a list?
Normalize every phone number to digits only, then match on that field first, since a phone number changes far less often than a business name. Use address matching as a second pass to catch franchise locations listed separately.
Can I cold email HVAC contractors found through a zip code search?
Yes, as long as the message follows CAN-SPAM basics: an accurate subject line, a physical address, and a working opt-out. The list itself is public business data, not personal consumer data, so building it is not the compliance risk, how you email it is.
