Crushed or kinked flex duct.
Return air starved of capacity
Duct leaks bleeding cold air into the attic
Filter and coil choking the blower
Check any that match. Two or more, and it’s time for a diagnostic – not another guess.
These four causes account for most calls like this we run across the Las Vegas Valley – Summerlin, Henderson, Spring Valley, and everywhere in between.
Flex duct is meant to bend, not collapse. We routinely find sections in Vegas attics where insulation, foot traffic, or a contractor’s tool has pinched the inner liner down to half its diameter. Clearing those restrictions is the core of a proper AC airflow repair. That single pinch can drop a room’s airflow by 50% – and the duct still looks “connected” from a distance.
Your blower can only move what the return lets in. Most Vegas tract homes built before 2010 have a single undersized return grille for the whole upstairs. Add a dirty filter and the system is gasping for air before it even tries to cool it. Static pressure climbs, motor lifespan drops, and the rooms farthest from the air handler suffer first.
Sheet-metal taps and flex connections that weren’t mastic-sealed leak 15–30% of your conditioned air into the attic. You’re paying to cool 140°F dead space. The vents downstream see weak, warm air — and the thermostat has no idea anything is wrong because it only reads the hallway temperature.
A “clean” MERV 13 filter in a system designed for MERV 8 adds restriction the equipment was never sized for. Pair it with an evaporator coil that hasn’t been cleaned in five summers and static pressure can double. The blower runs, the vents barely move, and the breaker eventually trips on a 110°F day.
From Summerlin to Henderson, here is how we’re keeping homes across the Las Vegas Valley cool and comfortable.
During this service visit, the Bob’s Repair team performed a full dryer vent cleaning for a home in Las Vegas.

We diagnose on-site, photograph what we find, and walk you through it before we recommend a single repair.
Every part and labor line itemized before we start. If we find something extra mid-job, we stop and call you before adding a dollar.
We fix the part that's failing. If a $40 capacitor solves it, that's the job — not a $1,200 replacement you didn't need.
We run the system, take a reading, and confirm the symptom that brought us out is gone. If it isn't, we stay and keep working.
Why won't one room cool down — even when the AC works fine? Nine times out of ten the AC unit isn't the problem: the real culprit is a broken "circulatory system" of ductwork in your attic that never delivers the cold air to that room. In this video, Bob's Repair shows what failing attic ducts look like and why fixing your airflow is the smarter (and far cheaper) move than buying a new AC unit.

What's the biggest energy leak in your attic? Hint: it's not the insulation. It's often the ductwork — after 15 years of wear, crushed, leaky, and filthy ducts can dump the air you've already paid to cool straight into your attic instead of your rooms. In this video, Bob's Repair replaces broken duct runs with a new airtight system, showing what a professional airflow upgrade looks like and why it's the real fix for hot rooms and high energy bills.

Why won't some rooms cool down even though the AC works — and why are the bills so high? Your expensive A/C unit is only as good as the ducts that deliver the air, and the old, leaky, collapsed ductwork hiding in most Las Vegas attics can waste over 30% of your conditioned air before it ever reaches your rooms. In this video, Bob's Repair shows the dramatic before-and-after of a full duct replacement and how it unlocks the true power of your HVAC system.

Why does a brand-new $10,000 AC still have weak airflow? The culprit is usually "cabinet leakage" — most installers tape the cabinet seams from the outside, but air escapes through hidden gaps inside the metal cabinet that tape can't reach. In this video, Bob's Repair demonstrates the step 90% of installers skip: pulling the blower motor out and sealing every joint from the inside, so the air you paid for actually makes it into your Las Vegas home.
