- Gas leak check complete
- Check gas pressure
- Airflow Fans
- Motor and blower mounting bolts are tight
- Fans are aligned and rotating freely
- Fan motor bearings are lubricated
There are other sections, too, like space and unit inspections, refrigerant requirements, voltage, pressure and temperature measurements.
4. New unit performance measurements
The HVAC inspection sheet also mentions a post-installation checklist. In addition, it includes initial performance readings of the system.
5. Final communication
It should mention what an HVAC technician has to inform the customer. For example, a brief about the system, warranty details, thermostat settings, maintenance agreement etc.

FAQ
Why is HVAC inspection necessary?
It helps in increasing the longevity of the heating and cooling system. Also, it keeps a check on energy efficiency. You can prevent expensive emergency repairs with period inspections.
When should you inspect HVAC?
A professional from Envigaurd can come and check your system once a year.
What are the 4 phases of planned maintenance?
They are:
Corrective maintenance: It is when some issues occur in the HVAC system and require immediate attention.
Preventive maintenance: It involves checking the system before any problem happens in HVAC.
Risk-based maintenance: A trained technician checks the design frequently.
Predictive maintenance: With the help of previous data, the inspector predicts when the system may fail.
What are the main concerns when inspecting the HVAC system?
The main concerns are as below:
Filters: If they are not kept clean, it can cause problems like airflow issues, high power bills, improper cooling and such.
The most common problem in HVAC is gas line leaks. It can be due to a cracked heat exchanger.
The exhaust flue should slope up to a vent through proper support.
The life expectancy of an HVAC system is at most 20 years. You may have to replace the parts after some years. To extend the years of the HVAC system, you should consult a licensed technician each year. Also, connect with centrifugal blower fans manufacturer for specific equipment.
The next issue is regarding electrical connections. If wires are faulty, it may lead to a home fire. Hence, it is essential to check the interior and exterior wiring. You can also add an electrical kill switch to cut the power during an emergency.
Clean the coil surface using a vacuum cleaner. If it is dirty, there are chances of low energy efficiency, and airflow may block.
Clogging of the drain hose can create moisture issues. Hence, it is a significant concern during HVAC system inspection.
Un-level condenser unit pushes stress on refrigerant lines. It should be at the proper level.
Checking the ductwork that is cracked or not correctly installed.
