HVAC contractor database: contacts, email checks and how to filter it
A HVAC contractor database is a searchable set of HVAC contractors with a phone, a website, an owner name where the company's site gives one and an email checked against the mail server. As of 13 Nov 2026, the 67Leads warehouse holds 13,278 sellable HVAC contractors with a phone. 1,078 of them have an email, 430 of those emails were confirmed by the mail server, and 1,039 name an owner on their own site.

Shortcut: the HVAC contractor lead list shows counts by state and city, the verified emails and owner emails pages apply the email filters, and the email verifier checks a single address.
What is in the HVAC contractors list
These are the live counts today:
| Group | HVAC contractors |
|---|---|
| Sellable HVAC contractors with a phone | 13,278 |
| With an email, verified or on a catch-all server | 1,078 |
| With an email the mail server confirmed | 430 |
| Confirmed email that is not a shared inbox | 374 |
| Owner name read from the company's site | 1,039 |
| Owner name and a confirmed email | 38 |
| No website on the listing | 2,871 |
Counts are listings that match today and move as the data refreshes. Not every company has an email, so a list of HVAC contractors with emails is smaller than a list of every HVAC contractor we hold. Call the rest.
What the columns are
Each row in the default export holds:
- Company and category. The business name and what its listing says it does.
- Phone and line type. The number, and whether it is a local or a toll-free line.
- Website and domain. The site on the listing, or blank when there is none.
- Email and email status. The address, read from the company's own website, and the result of the check.
- Owner name. Filled only when the company's site names one, with where it came from.
- Address. Street, city, state and postal code.
- Rating and review count. From the public listing.
How the emails are checked
Emails are read from the company's own website. None is guessed from a name pattern. Each one is then checked over SMTP: we ask the company's mail server whether that exact mailbox exists. Nothing is sent.
- Verified. The server said the mailbox exists.
- Catch-all (labelled risky). The server accepts every address, so the check cannot tell if this one is real. These are not counted as verified.
- Invalid. The server said the mailbox does not exist.
A check shows the state of a mailbox when it was run. It does not show that a person reads it, and addresses can go stale as people leave and domains lapse. Run the rows you plan to use through the email verifier again before a large send, and drop any hard bounce at once.

Who buys a HVAC contractor email list
- Equipment and parts suppliers. They sell to owners who choose brands and stock.
- Field service software. Scheduling, dispatch and invoicing tools for small shops.
- Lead generation and website agencies. HVAC owners spend on search and need a site that converts.
An HVAC company has two busy seasons, cooling in summer and heating in winter, and a slower spring and fall. Offers that save time or win maintenance contracts land best in the slow weeks, when the owner has time to read. Say which season your offer helps with and keep it to one idea.
Pair the email with a call when the list shows no email. A phone is on every row, and the cold email grader scores a draft before you send it.
Use it legally
Email to a business is covered by CAN-SPAM. The law makes no exception for business-to-business messages, so every commercial email needs:
- A true sender name and a subject line that matches the message.
- A clear sign that it is an advertisement.
- Your valid postal address.
- A working opt-out that you honor within 10 business days.
Keep a do-not-email list and check each send against it. The FTC's CAN-SPAM guide covers the rules and the CAN-SPAM checker tests a draft. Never send to a hard bounce twice.
Most states license HVAC contractors, and some require the licence number in advertising. Check the state licence before you write about a company, never claim a licence you cannot see, and leave out anything you cannot back up.
Do not text the phone numbers on the list as a first touch. Texting a business needs consent under the Telephone Consumer Protection Act, and a listed number is often the owner's own mobile. This is general information, not legal advice.
What it costs
Search and counts are free, with emails and phones masked. Your first 67 leads export free, and after that credits start at $6.70 per 1,000. Monthly plans are on the pricing page.
How 67Leads fits
67Leads is a search over public business listings and company websites. Companies are graded against the trade, and off-trade rows are never sold. Open the HVAC contractor lead list to filter by state, then use the verified emails pages to narrow to rows with an email. The email verifier and the lead list cleaner help before you send. Our guide to building a verified email list for local businesses explains the steps in more depth, and is buying an email list legal covers the law.
Questions
How many HVAC contractors are on the list?
As of 13 Nov 2026, 13,278 sellable HVAC contractors with a phone, and 430 of them have an email the mail server confirmed. That counts the listings we hold, graded against the trade, not every HVAC contractor in the country.
What does a verified email mean?
The company's mail server was asked whether the exact mailbox exists and said yes. A server that accepts every address is labelled catch-all and is not counted as verified.
Are the emails guessed from names?
No. Each address is read from the company's own website. None is built from a name pattern.
What is the difference between an HVAC database and an email list?
A database holds the whole record for each company: phone, website, owner name, rating and email. An email list is the same data cut down to the rows that have an email you can send to.
When should I email HVAC contractors?
Before the summer and winter rushes, or in the slow weeks between them. Mid-season, owners are in the field all day.
