Thorough AC Inspection You Can Rely On

A professional air conditioning inspection gives you a clear, honest picture of your system’s condition — before you buy, before you move in, or when something just doesn’t seem right. Chapman Bros. Plumbing, Heating & Air Conditioning provides expert AC inspection services across Union County, NJ, backed by more than 90 years of experience. Our inspections are diagnostic-first — designed to surface problems and give you actionable information, not to sell you services you don’t need.

When Do You Need an AC Inspection?

AC inspections serve a different purpose than routine AC maintenance & tune-up service. You should schedule a dedicated inspection when:

Buying or selling a home — understand the true condition of the HVAC system before closing
Moving into a new home — verify the system is safe, efficient, and ready to run reliably
After a long period of non-use — confirm no issues developed during off-season storage
Before the summer cooling season — catch problems early before they become emergency calls
Investigating a performance problem — uneven cooling, high bills, or unusual behavior that needs a professional diagnosis
Following a storm or power surge — check for electrical damage or refrigerant issues

If your inspection reveals a need for regular service, our team can move right into a full AC tune-up. If repairs are needed, we provide honest options with no pressure — see our AC repair services.

Frequently Asked Questions

What is the difference between an AC "tune-up" and a professional "inspection"?

A tune-up is focused on cleaning and optimizing performance, whereas an inspection is a deep-dive into the mechanical and electrical integrity of the unit. During an inspection, a technician isn’t just looking for dirt; they are looking for “pitting” in the electrical contactors, the thickness of the copper refrigerant lines, and signs of acidic oil in the compressor. We also verify that the installation meets current 2026 local building codes, ensuring that the safety overflows and electrical disconnects are properly grounded and functional.

Why do you inspect the "Delta-T" (Temperature Split)?

The Delta-T is the difference in temperature between the air entering the return vent and the air blowing out of the supply vent. In a healthy, properly charged system, this split should be between 16°F and 22°F. If the split is too low, it usually points to a refrigerant leak or a failing compressor. If it is too high, it indicates that air is moving too slowly through the system, often due to an undersized duct or a severely restricted evaporator coil. Measuring this split is the fastest way to verify the “health” of the refrigeration cycle.

What are "slugging" and "acid testing," and why are they part of an inspection?

If a system has had a previous motor burnout or has been running with a leak, moisture may have entered the lines. We perform an acid test on the refrigerant oil to check for contaminants that can eat away at the motor’s copper windings. We also look for signs of liquid slugging—which happens when liquid refrigerant (instead of gas) enters the compressor. Slugging is a “silent killer” of AC units, as liquids cannot be compressed and will eventually shatter the internal valves of the compressor.
