How to Develop a Complete HVAC Policy and Procedure Manual

READ TIME21 Minutes

Working in the HVAC industry can be complicated enough, but even more so is running an HVAC business. You don’t just have to set guidelines for what techs do in the field. You also have to lay down rules for how things should be done in the back office and how employees should act when they’re off-duty.

A good place to start in organizing all these regulations and instructions is to write them down in an HVAC policy and procedure manual. This gives all employees an accessible reference point for all of your company’s standards, best practices, and codes of conduct. In this article, we’ll dive into why and how to build this kind of manual, including:

  • 6 benefits of developing a thorough HVAC policy and procedure manual
  • 5 types of HVAC manuals for policy & procedure development
  • 30 essential components to include in every HVAC employee handbook
  • 5 best HVAC manual examples to base your employee guides on
  • How to write an HVAC policy and procedure manual
  • 4 critical FAQs that will help you write a better HVAC manual

We’ll begin with some reasons for why you should put together as thorough of an HVAC manual as you can.


6 benefits of developing a thorough HVAC policy and procedure manual

There are upsides to building a comprehensive handbook for your HVAC company besides serving as an accessible reference point for your policies & procedures, and these are the top benefits:

  • 1
    Increase efficiency with the latest technology and techniques – The latest technological HVAC advancements, work methods, and designs can tighten temperature control, manage air quality better, increase energy efficiency, and reduce environmental impact.Your HVAC manual should include what they are and how they work so employees know how to get the most out of them.
  • 2
    Give clear instructions to maintenance staff – You can reduce downtime, minimize errors, and help an HVAC system last longer if the techs who maintain it know exactly what to do for routine checks, repairs, and troubleshooting. 
  • 3
    Train new employees more effectively – A thorough manual makes it easier to train new maintenance employees and get them up to speed quicker on what they need to do.
  • 4
    Protect employees and assets – Having comprehensive safety protocols helps to reduce accidents and prevent costly damage to HVAC units and buildings, especially in an emergency.
  • 5
    Save your customers’ money – Optimized HVAC systems run longer and don’t use as much energy. This helps customers save money by lowering their utility bills and preserving equipment warranties, which they’ll appreciate.
  • 6
    Comply with legal requirements – The HVAC industry is regulated at the local, state, and federal levels, so the manual’s contents should be in line with the latest safety, environmental, and other industry standards. This helps you avoid non-compliance and the associated costs (fines, legal fees, and so on).


5 types of HVAC manuals for policy & procedure development

Different types of HVAC handbooks are written for different purposes. Therefore, you may need more than one type of HVAC manual to cover all of your policies and procedures, or a unified manual that incorporates some or all of these concepts.

  • 1
    Procedures & Forms – A manual that outlines how to do various HVAC tasks, often providing charts and formulas as aids. It also includes blank forms that you can copy and fill in as worksheets and reports, sometimes also giving examples.
  • 2
    Safety Manuals – Manuals that discuss potential safety hazards in an HVAC workplace. They also include directions on how to prevent said hazards from causing accidents, injuries, and other dangerous situations. 
  • 3
    Employee Handbooks – Manuals designed to help HVAC employees get familiar with a company’s operations, culture, and rules. They lay out an employee’s rights and responsibilities when working with the company.
  • 4
    Design Manuals – Manuals that explain the principles and methods behind designing HVAC systems. They cover things like how to plan ductwork, fit pipes, program control systems, select the right parts, calculate heating & cooling loads, and meet all relevant construction regulations.
  • 5
    Software-Integrated Checklist – This is a component of some HVAC management software programs that allows for building custom digital checklists. While not technically a policy & procedure manual, it can help to make sure employees follow a company’s policies & procedures. For example, it can make certain tasks at a worksite mandatory to complete and report on before a tech can submit a full field report, generate an invoice, and so on.

Integrating your HVAC company’s policies & procedures into field service management software allows you to quickly – even automatically – create checklists of things your techs need to do at a job site. A safety inspection is a major one, so download our free HVAC safety checklist to use as-is or as a template!


30 essential components to include in every HVAC employee handbook

How to write an HVAC policy and procedure manual

Now that we’ve covered what should be included in an HVAC principles and applications manual and what different types should look like, it’s time to put it all together. Here’s a step-by-step guide on how to craft and document your HVAC company’s policies & procedures so they work how you intend them to.

1. Identify the general policies and procedures you want to cover

Depending on the type of policy and procedure manual you want to write, you’ll be covering different topics. For example, a procedures & forms manual will include instructions for competing HVAC tasks and forms to fill in to report on work done. Meanwhile, an employee handbook will be less technical and focus on the HR side of your company: things like core values, employment policies, and codes of conduct.

Begin by determining the specific processes your manual will cover. These identified processes will form the foundation for more detailed HVAC policy and procedure development.

2. Add details to the processes

Once you have your main processes down, start filling in how employees should follow them. Use brief sentences and paragraphs with clear language to guarantee that guidelines aren’t confusing or open to being misinterpreted.

Break down multi-part processes into distinct, logical steps so it’s easier for the reader to digest the information and follow along. Also remember to add things like lists of necessary materials, lists of required tools & safety equipment and directions on how to use them (and notes on how to use HVAC inventory management software if you have it), and any other information that may be applicable to a particular task. That can include formulas for calculations your techs may need to make, or any other specific regulations they need to follow. 

3. Account for variants and special situations

There are cases in which something can be done multiple ways, or needs to be handled in a specific way, depending on the circumstances. This is especially true for HVAC since it covers heating, ventilation, and air conditioning, and these systems may need to be installed, repaired, or replaced in combinations. Add in information about these unique scenarios where each one makes sense, either at the end of sections on specific processes or near instructions where they’re most applicable.

4. Review the contents

Have people familiar with the procedures outlined in the manual – such as experienced techs and managers – look over the draft for anything that’s missing, incorrect, or unclear. They want to guarantee that the language, especially the jargon, is simple enough that your techs can understand it regardless of their experience level. They should also assess whether the procedures and instructions apply to situations that employees could reasonably encounter in daily work.

5. Test the practicality of your policies and procedures

Your policies and procedures are only good if they give you the results you want. Check this by having your employees follow your policies & procedures in exercises that mimic real-world scenarios and everyday work. See what works and what doesn’t, and have employees provide feedback on what they liked and disliked about the rules they had to follow. You may find unexpected issues that affect how you form your rules & instructions, or at least make for extra exceptions where things need to be done differently depending on the situation.

Also make sure your policies are flexible enough that they allow your company to grow, and can scale with your company as it does so. On one hand, you don’t want your company to be so bogged down in red tape that you can’t be profitable and efficient. On the other hand, you have to anticipate what direction your company is going in and how far it’s likely to go. Your policies & procedures should still make sense even if you get a larger and more diverse client base and workforce. Read our data-driven guide to commercial HVAC growth for an idea of how much your HVAC company is likely to grow over the course of 2 years. 

6. Revise any areas that need improvement and repeat the review cycle as necessary

Take the observations and feedback from the testing step and use them to rewrite any sections of your manual that need to be changed. Again, review your edits to check if they make sense, and test them to make sure they work in practical contexts. If you need to make further revisions, start this cycle again. Otherwise, you’re done!

7. Integrate key components into your HVAC field management software

We strongly recommend this extra step if your HVAC company uses field management software. By incorporating your policies & procedures into your HVAC field service software, you can make them accessible to all of your employees regardless of where they are. Plus, you can instantly update your policies & procedures from a centralized location – no need to revise or rewrite paper manuals for every one of your employees!

Some software even lets you implement your policies & procedures in your everyday workflows. For example, you could turn them into checklist items that your techs have to complete and cross off before they can finish their field reports and leave the job site. You could even connect those items to your other operations – sales, accounting, analytics, CRM, and more – to automate tasks without having to input the same information twice.

If you don’t have an HVAC field management software system, or are considering getting a new one, read our HVAC software buying guide for information about costing and top features. We also give advice on picking the right option for your company and getting the most out of it.


4 critical FAQs that will help you write a better HVAC manual

Here are some other things you may want to know about writing HVAC operation and maintenance manuals and other handbooks.

1. What exactly is an HVAC policy and procedure manual?

An HVAC policy & procedure manual is a document (or one of a set of documents) that lays out the rules an HVAC company operates by and the proper methods techs should use to complete HVAC tasks. This can include:

  • The roles of different positions
  • How the company hires and trains employees
  • The steps techs should take to do their HVAC work
  • How techs can keep themselves safe in the workplace, and what they need to watch out for
  • Standards to follow when taking measurements, setting schedules, and solving problems
  • How employees should deal with customer inquiries, requests, and feedback
  • How customer details and other administrative information are processed, stored, and protected
  • Other environmental and industry-specific regulations the company has to follow

2. Who needs an HVAC policy and procedure manual?

All employees of an HVAC company should have the company’s policy & procedure manual, whether that means physical copies or access to a digital version (or both). Everyone in the company needs to understand what their responsibilities are, how to do their jobs properly, and how they’re expected to act towards customers and each other.

3. How often do you need to update your HVAC employee handbooks & manuals?

A general guideline is to update your HVAC customer service handbook and other manuals at least once a year. A lot can change in 365 days, so it’s good to review your handbooks and make additions (or deletions) where things have changed.

Ideally, though, you should update your handbooks more frequently to reflect significant changes both inside and outside your company. These can include:

  • Your company merging with, acquiring, or being acquired by another company
  • Creating new job roles, or changing the responsibilities of existing job roles
  • New or altered benefits, and eligibility requirements for them
  • Introducing new technologies to your company
  • New technologies, equipment, or work techniques necessitating new safety guidelines
  • Changes to your company’s performance standards
  • Changes to employment law and other regulations

If your handbooks are integrated with an HVAC field service platform, you can make changes to them at the admin level and they will automatically update and sync for all of your employees at once! 

4. Is the HVAC industry subject to regulations your manual needs to follow?

Yes. Your manual will need to include information and instructions on complying with US HVAC regulations and standards related to:

  • Energy efficiency
  • Refrigerant management
  • Environmental impact (via EPA certification)
  • Employment law
  • Workplace safety and insurance
  • Building codes such as the IRC and IMC
  • State-specific requirements
  • Local ordinances from cities and counties


Keeping track of your HVAC company’s policies and procedures is important, but it doesn’t have to be hard. Create your manuals on the BuildOps field service management system and you can update them for all employees at any time – no need to rewrite your manuals by hand or update your handbooks on separate devices. Plus, you can use your policies and procedures to build software-integrated checklists that make sure your techs are following your guidelines while they’re out in the field. Even more, checklist items can be connected to other functions to automate things like invoicing!
