Recurring commercial work
How to get commercial HVAC maintenance contracts
Published by B2B Lead Growth · First published: September 20, 2026 · Last updated: November 6, 2026
Commercial HVAC maintenance contracts are won one account at a time, not through advertising. The contractor picks the buildings they want, reaches the person who owns the vendor decision, and gives that person a reason to start a conversation.
That is a different job from getting found. Many of these buildings already contract their HVAC maintenance — the Department of Energy’s federal O&M guide put it at about 40% of nonresidential buildings, citing a 1997 study — and the person who would add a contractor is someone with a vendor list and a budget cycle, not someone searching. This page covers the four agreement structures buyers are offered, which accounts buy them, and how to reach the person who decides. What your agreement contains and what it costs stay your trade, not ours.
Why these accounts are contacted, not captured
Advertising works when a buyer is searching. For recurring commercial work, most are not. They have someone on file, the equipment is running, and replacing a vendor is nobody’s priority until a person changes, a building changes hands, or a site is added. Those moments are public, and they are the reason to write.
It also means the ask matters more than the pitch. “Would it help to have a second contractor on file?” is a question a busy manager can answer today. “Can we meet to discuss your HVAC needs?” asks for a commitment before you have earned one.
Which accounts actually buy recurring agreements
- Account type
- Property management firms
- Why an agreement suits them
- They run buildings they do not own, and an owner expects the building covered without being asked twice.
- Who owns the decision
- The property manager, usually with an owner or a board above them for anything large.
- Account type
- Multi-site operators
- Why an agreement suits them
- One brand, many roofs. A single agreement across sites is less work for them than a vendor per location.
- Who owns the decision
- A facilities lead or an operations manager at the head office, not the site staff.
- Account type
- Owner-occupied commercial buildings
- Why an agreement suits them
- The owner carries the cost of a failure directly — lost use of the building, not a line in a budget.
- Who owns the decision
- The owner, or whoever they have put in charge of the building.
- Account type
- Institutions with in-house teams
- Why an agreement suits them
- The team handles daily work and buys outside help for specialist equipment, overflow and after-hours cover.
- Who owns the decision
- The facility or plant manager who already holds a budget for outside contractors.
The three buyers above behave differently enough to need different first messages. Each has its own page: property managers, in-house facility teams and building owners.
Recurring work is worth more only when you want it and can staff it on schedule. Whether a given maintenance account beats a one-time job for your team, by distance, crews and the cost of winning it, is the subject of which commercial HVAC work is worth pursuing.
Two kinds of work often come from customers you already serve: a repair proposal written on a maintenance visit that was never approved, and a customer’s other buildings. See how to follow up commercial HVAC unsold estimates and how to win more buildings from a customer you already serve.
The four agreement structures commercial buyers are offered
- Structure
- Full coverage
- What it covers
- All labor, parts and materials plus emergency service, for all of the building's equipment or only the critical pieces, with full preventive maintenance included. Repair-and-replacement cover can be added for a fee.
- How it is usually priced
- Usually the most expensive in the short term, and the easiest to budget. The contractor carries most of the risk.
- Who it tends to suit
- Owners who want an easy budget and want the contractor to carry most of the risk. The guide adds that over the long term it may prove the most cost-effective, depending on the owner's goals.
- Structure
- Full labor
- What it covers
- All the labor to repair, replace and maintain most mechanical equipment. The owner buys the equipment and parts, and installing major plant such as chillers and boilers is usually excluded.
- How it is usually priced
- The second most expensive. Emergency calls are either built in or billed as labor on top.
- Who it tends to suit
- Owners of very large buildings or several properties who buy parts in bulk.
- Structure
- Preventive maintenance
- What it covers
- A fixed schedule of tasks: belts and filters, cleaning coils, lubricating motors and bearings, cooling-tower care, testing and calibrating controls. The contractor usually supplies the materials.
- How it is usually priced
- Generally a fixed fee. Repairs and emergency calls are often billed on time and materials, so the owner carries most of the risk.
- Who it tends to suit
- The guide calls it popular with owners and widely sold, and cheaper up front than full coverage or full labor.
- Structure
- Inspection
- What it covers
- A set number of inspections a year. Small fixes, like a dirty filter or a broken belt, are done on the spot; otherwise the contractor reports what is broken or about to break.
- How it is usually priced
- A fixed annual fee, the least expensive of the four in the short term. Breakdown calls are billed on time and materials.
- Who it tends to suit
- Smaller buildings with simple systems. The guide notes the contractor who holds one is more likely to get the call when something breaks.
Two more arrangements appear in the same guide: an end-result contract, where the contractor runs the equipment and is paid on the comfort it delivers, and incentive clauses that reward a contractor for energy savings beyond the contract’s requirements. For what a maintenance visit should cover, ANSI/ASHRAE/ACCA Standard 180 sets minimum inspection and maintenance requirements for commercial building HVAC, to preserve comfort, energy efficiency and indoor air quality.
Some buildings are now required to have a maintenance plan. Washington’s Clean Buildings Performance Standard requires its Tier 1 buildings to run a written operations and maintenance program, and Oregon’s standard requires an O&M plan from its Tier 1 buildings. Those laws, with their dates and official sources, are in our table of commercial building performance standards.

The sequence, start to handover
1. Pick the accounts
Building type, equipment you know, and close enough for a technician to reach. A written profile first, so the list is a decision rather than whatever the search returned.
2. Find the person who owns the vendor decision
Not the front desk, not the leasing agent, not the registered agent. The person who decides who is on the vendor list, by name where a public source gives it.
3. Write with a reason you can show
A public fact about that account, with a link. No source, no contact. Its own page saying what it runs is reason enough to write; something dated, like a new manager, moves it up the list, and an account with nothing dated is worked later, not dropped.
4. Earn a conversation
The first message asks for a reply, not a meeting. Follow up because you have something to add, not because a sequence says day four.
5. Let the buyer state the need
What they need, in their own words — coverage for a site, a second contractor on file, a contract they are unhappy with, a budget cycle coming up.
6. Hand it to the people who quote it
The site visit, the coverage schedule, the price and the agreement are the contractor's work. Everything before that is what this page is about.
Steps 1 to 3 are the research method, written out in full on how to find commercial HVAC accounts. Step 3’s “reason you can show” has its own page: what counts as a reason to contact an account.
What the first message can honestly say
You have not seen the building. You do not know what the equipment is, how old it is, or whether the current contractor is doing a good job. So the message brings an opportunity and never implies a problem you have not observed.
Subject: Second HVAC contractor on file for [building name]?
Hi [first name] — I saw that [management company] took over [building name] in [month]. Congratulations on the addition.
We service [equipment type] on [property type] buildings around [area], and we are about [drive time] from that address. A few managers keep us on file as a second contractor for after-hours calls and for the weeks their first call is stretched.
If that would be useful for [building name], I can send a one-page summary of what we cover and what we would need from you. Would that help?
[Your name], [your title], [your company]
[Your company's postal address]
Reply “stop” and I will not write again.
Every bracket is a value the writer has to know before sending. A message that works with the brackets left in is a message that could have gone to anyone, which is the definition of the email these managers already delete.
The rules behind that example — what belongs in each part, the follow-ups, and what US law requires on a commercial email — are on writing a commercial HVAC cold email.
Where this work stops
This matters more here than anywhere else on the site, because a maintenance agreement is exactly the kind of work someone will offer to “handle end to end”. Nobody who has not stood in the mechanical room can scope it. When we run this for a contractor, no message we write may price, size, diagnose, scope, negotiate or close the buyer’s work, and our software checks every one before it can send.
What we hand over is the conversation and what the buyer said in it. What you do with it is the part only you can do.
What not to do
- Do not tell a manager their building has a problem. You have not seen it, and they know you have not.
- Do not open by asking to replace their contractor. Ask to be the second name on the list; it is a smaller decision and it is the one they can make today.
- Do not send the same message to four people at one company. One account, one conversation.
- Do not attach a capabilities brochure to a first email. Offer it, and send it when asked.
- Do not measure this by emails sent. Count accounts researched, decision-makers reached, and conversations that actually happened.
- Do not keep writing to someone who asked you to stop — and at a company, one person’s request covers their colleagues.
Or have the accounts researched and reached for you
B2B Lead Growth runs this for established commercial HVAC contractors. It researches the accounts and writes to the decision-makers in your name, from one dedicated mailbox on your company's commercial subdomain, used only for this outreach. When a buyer agrees to talk with your team, it is a Qualified Conversation, and we introduce you by email, with the whole conversation. On Managed Outbound, your team confirms the need and books the meeting from there. On the Opportunity Engine, we first confirm the need and the timing and set the next step. What the service includes, and what it costs. The free commercial HVAC pipeline audit is a short written diagnostic of your own commercial pipeline: the biggest bottleneck, the kinds of accounts to target and three prioritized actions. No call is required to receive it. If you are weighing a firm that phones managers and books meetings instead, the difference is set out in commercial HVAC appointment setting vs managed outbound.
The exact wording of what we hand over is published on sample deliverables, and every term used above is defined on definitions.
Common questions
What types of commercial HVAC maintenance contracts are there?
Four common structures, as the U.S. Department of Energy's federal O&M guide describes them: full coverage (labor, parts and emergencies), full labor (the owner buys the parts), preventive maintenance (a fixed schedule for a fixed fee, with repairs often billed on time and materials) and inspection (a set number of visits for a fixed annual fee). They differ in who carries the cost when something breaks.
How do commercial HVAC contractors get maintenance contracts?
One account at a time. The contractor decides which buildings and operators they want, finds the person who owns the vendor decision at each, and contacts that person with a real reason. Recurring agreements are rarely won from advertising, because the buyer is not searching — they already have someone, or they have not thought about it this quarter.
Is it worth contacting an account that already has an HVAC contractor?
Usually it is the only kind worth contacting. A commercial building already has someone. What changes is the people: a new property manager, a new owner, a new site. Asking to be the second contractor on file is a smaller request than asking someone to replace a vendor, and it is the one most buyers can say yes to.
How long does it take to win a maintenance agreement this way?
Longer than a service call and shorter than a construction bid, and it depends on the account's own budget cycle rather than on how many emails were sent. We do not publish a timeline, because we would be inventing it. What is measurable is activity: accounts researched, decision-makers reached, conversations that happened.
Do you write the maintenance proposal or quote the work?
No. We research the accounts, reach the decision-makers in your name, and introduce your team to each buyer who agrees to talk, with what the buyer told us. The site assessment, the coverage schedule, the price and the agreement are yours, on either plan. We never price, scope or diagnose a building's work.
What is the difference between a service agreement and a one-off repair customer?
A repair customer calls when something breaks and may call someone else next time. An agreement is a standing arrangement to cover named equipment on a schedule. The outreach that wins the second is different from the marketing that wins the first, because the buyer is a named person with a vendor list rather than whoever answers the phone.
