HVAC Inspection Checklist: 9 Free Templates for Quality Inspections

What is an HVAC inspection?

An HVAC inspection includes a full check of the system’s safety, performance, airflow, and major mechanical components.

That means your technicians are looking for:

• Airflow restrictions
• Electrical issues
• Refrigerant problems
• And early warning signs that could turn into expensive breakdowns

Implementing a standardized inspection process for your HVAC company keeps everyone on the same page. For techs in the field, a checklist works like a pre-flight inspection for an airplane: it keeps small misses from becoming big problems later.

What to include in an HVAC inspection checklist

Your HVAC system inspection checklist should include tasks to check every component found in an HVAC system. Make sure to check these types of components, no matter what unit type you’re inspecting:

• Heating and cooling elements: In your customers’ furnaces and AC units, inspect heat strips, spark igniters, flame sensors, evaporator coils, condenser coils, and condensate drain lines.
• Air filters: Check the air filters on every unit for excessive dust, dirt, ice buildup, or other obstructions that prevent proper airflow. Many customers neglect to clean their air filters—a regular inspection and maintenance task that’s important for indoor air quality.
• Blower assembly: Look carefully at every HVAC unit’s blower and its fan blades, motor, filter, and supporting components.
• Electrical wiring and controls: Check for proper connection of every wire that keeps the HVAC system running, including the thermostat wire system.
• Pressure and charge: Always measure the pressure and charge of a customer’s AC unit or packaged HVAC system to improve the system’s energy efficiency and lifespan.
• Ductwork: Check the upper and lower ducts and the insulation surrounding them for damage, such as damp spots or mold.

Once you’ve added the checklist items from this article to your own checklist, consult your most experienced technicians on what other tasks to include.

In addition to standard HVAC preventive maintenance and inspection tasks, your checklist should also include:

• Customer name and contact details
• Building address
• Date of inspection
• Name and title of the HVAC technician conducting the inspection
• Recommended date for next inspection

When you’re done with the inspection, provide a written report detailing your findings. This is easy to do with HVAC apps like Jobber since you can send a copy of the completed checklist directly to the customer.

How to create a digital HVAC inspection checklist

Paper inspections are easy to lose and even harder to manage. Be more efficient with inspections by checking off tasks from your smartphone or tablet.

You can easily create custom site inspection checklists in Jobber to keep a digital, shareable record of the tasks you or your technicians have completed.

Turn any inspection process into a digital checklist your techs can access from their phone or tablet. They check off items as they go, add photos and notes, and the completed checklist is automatically attached to the job record.

Just add your HVAC inspection items to a new checklist. Once you attach that list to a scheduled visit in Jobber, your techs can access it in your HVAC CRM and check off items as they go.

How often should HVAC systems be inspected?

You should inspect, clean, and tune up all HVAC systems at least once a year, but ideally twice. Inspect heating systems in the fall and air conditioning systems in the spring so your customers’ HVAC equipment is prepared to handle severe weather.

It’s also a good idea to inspect a furnace or AC system a few weeks after installation or heavy repairs, just to make sure the system is functioning properly.
