Significant Air Leaks at the HVAC System

On a recent home inspection in Las Vegas, we found significant air leakage around the home's HVAC system. It appeared that a panel had previously been cut open and later replaced, but the sealing work from that repair was not properly completed.

It's easy to overlook a gap or poorly sealed panel around an HVAC system, but air leakage can affect how efficiently the system operates and how effectively conditioned air reaches the home.

What This Means For You

Your HVAC system relies on sealed components and ductwork to move conditioned air where it needs to go. When there are gaps or poorly sealed areas, some of that air can escape before it ever reaches the living space.

In Las Vegas, where air conditioning systems work hard for much of the year, unwanted air leakage can make it more difficult to maintain comfortable indoor temperatures and may cause the system to work harder than necessary.

The visible leak also raises another question: whether there are additional areas of leakage that aren't immediately apparent.

Why It Matters

An improperly sealed HVAC system isn't necessarily an emergency, but it can affect both comfort and energy efficiency.

A system that is losing conditioned air may need to run longer to maintain the desired temperature. Over time, that can contribute to increased energy consumption and additional wear on the equipment.

In this case, the quality of the previous repair was also a concern. Poorly sealed repairs can introduce new leakage points, which is why simply sealing the visible area may not tell the whole story.

What We Typically Recommend

When significant air leakage is observed, we recommend having a qualified HVAC professional evaluate the system and perform a duct leakage test.

A duct leakage test can help determine how much air the system is losing and identify additional areas that may need attention. The HVAC contractor can then properly seal the affected areas and determine whether the previous repair created any other issues.

Main Takeaway for Las Vegas Home Buyers

HVAC problems aren't always obvious. A system can appear to be operating normally while still losing conditioned air through poorly sealed panels, connections, or ductwork.

This is especially important in Las Vegas, where your HVAC system plays a major role in keeping your home comfortable throughout the year.

A professional home inspection can help identify visible HVAC concerns and recommend further evaluation when a problem requires specialized testing.
