How to generate HVAC leads without paying per lead

Past customers, builders and local search give an HVAC business its cheapest leads. Here are six routes ranked by effort, and when to add bought leads.

Updated 13 November 2026 · For builders, trades and home services

If you are working out how to generate HVAC leads without paying for each one, start with people who already know you: past customers, builders, electricians and agents who send you work, and homeowners who found you on a local search. Buying leads or running ads fills the gaps. Here are six routes ranked by effort, with where bought leads fit.

This is written for any market. In the United States the trade is HVAC; in Australia and New Zealand people say air conditioning or ducted air, and the Australian detail is in our ducted air guide. PreBuild works in Australia and New Zealand and is opening in the United States; it is not supplying US HVAC leads yet.

How to generate HVAC leads from past customers

Effort: low. Every system you installed or serviced will need servicing, repair and, one day, replacement. You already hold the name, address, system age and phone number.

  • Keep a simple list: customer, address, system, install date, last service.
  • Send a short reminder before the busy season, by text or email, offering a service visit.
  • When a system is getting old, tell the owner before it fails, and offer a quote.
  • Ask each happy customer for a review and a name of someone else who might need work.

Check the rules on marketing messages where you work. Texts and emails for marketing have consent requirements in Australia, New Zealand and the United States, and they are not the same. Ask your adviser, and use the regulator’s own guidance.

Builders, electricians and agents

Effort: medium. Builders need an air conditioning or heating contractor on every new house. Electricians meet homeowners who are asking about a unit. Real estate agents hear about unit problems before a sale. Each can hand you a steady run of work.

What they want is simple: you turn up, quote quickly, finish clean and do not make them look bad. Introduce yourself with a one-page sheet: what you install, your licence number, the area you cover, how to reach you, and how fast you quote. Then do the first job well. Builders remember the contractor who made their handover easy.

Local search and reviews

Effort: medium, and it builds. Someone who searches “AC repair near me” sees a map of businesses before any website. Google’s help page on local ranking says the number of reviews and positive ratings can help a business’s local ranking, and that there is no way to request or pay for a better one.

In practice:

  • Claim and complete your Google Business Profile: services, area, hours and phone.
  • Ask for a review after every job, while the cool air is still fresh in their mind.
  • Reply to every review, good or bad.
  • Keep your name, address and phone the same everywhere.

A simple website with a page for each main job, such as “replace ducted system” or “split system install”, helps people confirm you are the right business.

Seasonal timing

Effort: low, once you decide. HVAC work follows the weather, and the weeks before the first hot or cold spell are quieter than the weeks during it. Use that quiet stretch for the free routes above: send the service reminders, ring the builders you want work from, and ask for the reviews you missed. During the peak, keep the phone answered and keep a short waiting list rather than letting calls ring out.

The seasons are opposite in the two hemispheres, so a US guide and an Australian one will give different months. Use your own enquiry history for the dates. What to run in each stretch with paid ads is in Google Ads and Facebook ads for HVAC.

Quote follow-up

Effort: low, and the most overlooked. Many jobs are lost after you have already spent the time to quote. A homeowner gets three quotes, hears nothing for a week, and signs with whoever called back.

Write down the date you sent each quote, and ring or message after a few days to ask whether they have questions. Do not push. Ask if they have a decision date, and offer to adjust the scope. If quotes are where your week goes, PreBuild’s quote follow-up covers what it does for clients. Ringing a fresh enquiry quickly matters just as much as following up an old one.

Where bought leads fit

Effort: money more than time. Buying leads or running paid ads is the route when the free ones are not enough: you are new, you have just opened in an area, the diary is empty or you have spare crews. Free sources build slowly. Bought leads are fast, and they cost money for each one.

Before you buy, work out what a signed job is worth to you and what you can pay for a lead. Divide what a signed job leaves you by how many leads it takes to win one, and that is your ceiling. Buying HVAC leads compares shared, exclusive and call leads and how to test a seller.

Whichever route, the same rule applies: a lead is only worth something if someone rings it back quickly and the person was ready to buy. PreBuild Systems rings each homeowner who enquires before one business gets them; the ducted air and HVAC page covers this trade. In the United States that work has not started yet.

Common questions

How can I get HVAC leads for free?

Past customers, referrals from builders, electricians and agents, reviews and a complete Google Business Profile. They cost time, not money, and they build slowly.

How do I get more HVAC leads in the off season?

Offer service visits and replacement quotes before the peak, follow up old quotes, and work with builders on new houses, whose timing does not follow the weather as closely.

Are bought HVAC leads worth it?

They can be when they are fast, checked and not shared with many others. Test a small number and track how many become signed jobs.

What is the best way to get HVAC leads?

The best way is usually a mix: people who know you, a strong local profile and a paid source for the gaps.
