HVAC Inspection: Process, Price, Checklist, and Tips

An HVAC inspection includes all the steps and checks carried out to find potential issues in the heating or cooling equipment. It helps homeowners and business owners catch bigger issues at initial stages before they develop into major headaches. In New Jersey, where summers are hot and humid, and winters come with sub-zero temperatures, equipment experiences frequent failures. In this context, scheduling inspection service is highly important to prevent such HVAC failures.

In this blog, we will cover a brief overview of HVAC inspection, including price, process, checklist, and expert tips.

Step-by-Step HVAC Inspection Process

The process may vary based on the equipment you inspect, your approach, and accessibility. Here are the standard steps you can expect.

System Review

The technicians conduct a brief assessment of the equipment's condition, age, and visible signs of wear and tear.

Component Inspection

The technicians check each component carefully. Advanced tools and equipment such as digital multimeters, leak detectors, and scoping cameras are used to detect problems that are impossible to detect with the naked eye.

Operational Efficiency Check

The technicians check how a system performs. They notice and report unusual sounds, odors, frequent short-cycling, or abnormal patterns while the equipment is running.

Safety Checks

The technicians check safety alarms, such as carbon monoxide detectors in the case of furnaces, electrical breakers, limit switches, and refrigerant leak detection setups, and report any flaws in those safety checks.

Reporting of Issues

The inspection service concludes with a report on all possible issues and worn equipment. If you hire a professional inspection partner such as Lehigh HVAC, you also get a detailed report on how to fix those faults and how much you can expect to pay for troubleshooting.

The entire process of HVAC inspection is usually completed in 2 to 3 hours, though the time is more for large, commercial HVAC systems.

HVAC Inspection Checklist

Not every HVAC technician carries out the inspection in the same way, and not all inspections detect all flaws. That’s why we recommend you follow the Lehigh HVAC checklist to make sure you inspect every component the right way.

• Thermostat: Check settings and response.
• Air filter: Check for dirt, blockages, and proper fit.
• Electrical system: Inspect connections and check operating readings.
• AC or heat pump: Inspect coils, refrigerant-related components, and condensate drain.
• Furnace: Inspect the burner, ignition system, heat exchanger, and safety controls.
• Boiler: Check for leaks and inspect operating controls and applicable safety components.
• Ductwork: Check for visible damage, air leaks, and disconnected sections.
• Blower: Check airflow and operating condition.

When Should You Schedule an HVAC Inspection?

HVAC inspection needs to be scheduled at least twice a year. The best strategy is to schedule it before the heating and cooling seasons to ensure reliable operation during peak days. Here is the recommended inspection schedule.

Early Spring: Inspect AC equipment before summer.

Early Fall: Check furnaces, boilers, and other heating equipment.

Before Buying a Home: Arrange a dedicated HVAC inspection if needed.

Beyond these, we recommend scheduling an inspection service immediately after you notice unusual signs from your HVAC appliance.

Expert Tips by Lehigh HVAC

Though HVAC inspection costs a few hundred dollars, it has a significant impact on how you get your system fixed. That’s why it should never be scheduled blindly or handed over to street technicians. Here is what we recommend in this regard.

• Request a written quote and inspection scope from multiple companies

• Verify relevant licenses, insurance, and company certifications

• Confirm whether heating and cooling units are both included

• Ask for a written report of findings

• Check whether diagnostic tests or repairs cost extra

• Compare recommendations before approving major repairs
