What to Expect During an HVAC Inspection

By All-Temp Heating & Cooling

If you’re unfamiliar with the process of an HVAC inspection, you might feel anxious about the appointment. The good news is that the process is easier than you may think. Discover what to expect during an inspection so that you can schedule your next appointment with confidence.

How Long Does an HVAC Inspection Take?

One of the best ways to enjoy energy savings is to ensure an HVAC inspection is on your seasonal checklist. This brief service usually takes less than an hour to perform.

If a technician discovers a problem, repairing the issue can extend the time it takes to complete the service call. In either case, this essential maintenance service still takes less than an afternoon and leaves you with optimal cooling.

Do I Really Need an HVAC Technician to Inspect My System?

Thinking about performing the HVAC inspection yourself? Unless you work professionally in the industry, this is usually a bad idea. Servicing the equipment without the proper certifications can invalidate your AC warranty. More importantly, you might overlook an important component that requires the attention of professional eyes.

The cost of annual maintenance is usually low when compared to the value it provides. You can save even more on the service by participating in HVAC maintenance plans.

The Inspection: What to Expect

Technicians often follow a general HVAC inspection checklist. While some heating and cooling companies offer extra services, any inspection should include these key details:

Test the Electrical Connections

HVAC inspections start by checking electrical connections throughout the system. Securing the connections between the thermostat and air handler and between the air handler and the outdoor compressor eliminates many common problems. The technician will also look for wiring shorts and other issues that might interrupt the flow of electricity.

Inspect and Clean the Outdoor Compressor

The outdoor compressor requires plenty of attention each year. The technician may remove the outer case to gain access to the condenser coils and other components. They will clean the coils and check the refrigerant level.

Low refrigerant indicates a leak, so they may repair or replace the ruptured line. Before restoring the outer case, the technician will top off the refrigerant. They will also test the compressor’s operation at this time.

Inspect and Clean the Indoor Air Handler

Schedule air duct cleaning along with your inspection every three years. While servicing the indoor air handler, the technician will clean the evaporator coils, lubricate the motor, and check the belts on the blower fan. This is also when they replace the air filter and clean the condensate drain line.

Check Seasonal Equipment

Preventative HVAC inspections differ at this point in the process. If it’s a spring/summer inspection, the service concludes here. However, a fall or winter inspection requires servicing the furnace or other heating equipment.

If you have a traditional furnace, the HVAC technician will examine the heat exchanger, fuel lines, gas ports, and other parts. They will make sure the unit doesn’t leak natural gas or carbon monoxide. As with the AC air handler, the technician will conclude the inspection by testing the equipment.
