Artificial intelligence (AI) is a rapidly evolving field that has the potential to revolutionize many industries, including business, healthcare, education — and HVACR. One of the most exciting developments in AI is the emergence of language models — or chatbots — like ChatGPT, which is designed to generate text that is more coherent, consistent, and diverse than traditional language models.

Currently free to use, ChatGPT is a pre-trained model developed by OpenAI that uses deep learning algorithms to generate human-like text based on a given prompt or input. It can be fine-tuned for specific tasks such as answering customer service inquiries or composing emails and has the potential to greatly improve the efficiency and accuracy of many different types of industries.

One of those industries is HVACR, where ChatGPT could be used to help contractors by automating repetitive tasks, allowing them to focus on providing high-quality service to customers instead. Some of the ways the chatbot can help contractors include:

  • Generating automated responses to frequently asked questions about HVACR systems, allowing contractors to provide quick and accurate information to customers;
  • Helping write professional and effective emails, quotes, and proposals;
  • Generating marketing and advertising content to promote HVACR services and increase business;
  • Providing technical assistance, such as troubleshooting HVACR problems and recommending solutions; and
  • Helping generate training material for employees.

These last two points are of particular interest. By typing in a simple question, the chatbot can generate diagnostic information for HVACR system issues, which can then help technicians solve problems more quickly and accurately. For example, asking ChatGPT to diagnose a frosted evaporator coil results in this response:

There are several reasons why an evaporator coil may become frosted:

  • Low refrigerant levels: If the refrigerant levels in the system are too low, it can cause the evaporator coil to freeze. This is because the refrigerant is responsible for absorbing heat from the air, and without enough refrigerant, the coil will not be able to absorb enough heat to prevent freezing.
  • Dirty air filter: A dirty air filter can restrict airflow to the evaporator coil, causing the coil to freeze.
  • Blocked or restricted airflow: If the airflow to the evaporator coil is blocked or restricted, the coil may freeze. This can be caused by a number of things such as dirty ducts or registers, closed or blocked vents, or a malfunctioning blower fan.
  • Thermostat issues: If the thermostat is not working properly, it can cause the evaporator coil to freeze.
  • Obstruction in the drain line: A blockage in the drain line can cause water to back up and freeze on the coil.

It's important to fix the issue as soon as possible, as a frozen evaporator coil can lead to decreased efficiency and can cause damage to the unit.

ChatGPT can also generate materials such as instructional articles, troubleshooting guides, and FAQs to support in-house training programs. In addition, it can simulate customer interactions, allowing technicians to practice responding to common questions and concerns in a realistic setting. For example, when asked how to respond to a customer who thinks an air conditioner is too expensive, ChatGPT offers the following:

  • Understand their concerns: Find out why they think the air conditioner is too expensive. Are they comparing it to a lower-quality unit? Are they on a tight budget? Understanding their concerns will help you address them more effectively.
  • Provide a detailed explanation of the costs: Explain the costs associated with the air conditioner, including the cost of the unit, installation, and any additional materials or labor that may be required.
  • Compare costs with the benefits: Explain the benefits of the air conditioner, such as energy efficiency, durability, and long-term cost savings. Explain how the cost of the unit may be offset by energy savings in the long run.
  • Offer financing options: If the customer is unable to afford the air conditioner upfront, offer financing options that can help them spread the cost over time.
  • Provide a written estimate: Provide the customer with a detailed, written estimate that outlines the costs associated with the air conditioner and the benefits it will provide. This will help them make an informed decision.
  • Provide a guarantee or warranty on the unit: Provide the customer with a guarantee or warranty on the unit to give them peace of mind in their investment.
  • Provide an alternative solution: If the customer cannot afford the recommended solution, offer an alternative solution that fits their budget while still meeting their needs.

It's important to be patient, understanding and provide all the information customers need to make a decision that best fits their needs and budget.

As can be seen here, ChatGPT is a powerful tool that can help HVACR contractors and technicians in a number of different ways. This chatbot was also helpful to your humble correspondent, who used it to “write” almost the entirety of this editorial (including the ‘punny’ headline). I encourage you to play around with ChatGPT (, as you could find it to be a game changer.
