A
Visual + airflow assessment
Every joint, register, return, and run inspected. Static pressure measured. Airflow at each register logged.
Your attic ducts are running through a 150°F oven. We fix that.
Duct sealing, re-routing, and blown-in attic insulation built for the Mesilla Valley. Most uneven-cooling and high-bill problems trace back to ducts. We measure, we seal, we re-balance, and we tell you what we found.
When ducts are the problem
If any of these is true, your AC isn't the issue. Your ducts are.
Replacing the AC won't fix a leaky duct system. We'd rather sell you the cheaper fix that actually works.
One room is always 5°F off the others
Almost always a duct sizing, run length, or balancing issue.
Vents whistle, rattle, or have weak airflow
Static pressure problem. Often a too-small return or kinked flex duct.
Bills jumped without an equipment change
Insulation compressed or torn off, or a duct came apart in the attic. Both common in Mesilla Valley homes built pre-2005.
Dust accumulates fast at the registers
Unsealed return-side joints pulling attic dust into the system.
You can hear the AC running but barely feel it
System is moving air but most of it is leaking out before reaching you. Classic desert duct failure.
What's included
A duct & insulation project, end to end.
B
Mastic-sealed joints
Foil tape gets brittle and falls off in attic heat. We use water-based mastic at every plenum, branch, takeoff, and boot. It stays.
C
R-8 duct insulation
Where ducts have to live in the attic, they get wrapped in R-8 minimum. We re-secure or replace any compressed or torn insulation.
D
Re-routing where possible
If we can pull a duct into conditioned space, a chase, soffit, sealed crawlspace, we do. The cheapest BTU is the one that doesn't have to fight a 150°F attic.
E
Custom sheet metal
Where flex doesn't fit (adobe, mobile homes, additions), we fabricate transitions and trunks in our own shop, on the truck.
F
Blown-in attic insulation
Optional add-on. R-38 minimum to current Doña Ana County code. Often pays back faster than any other improvement.
How a duct project goes
From assessment to balanced airflow.
1
Assessment.
Attic walk-through, static pressure measurement, room-by-room airflow. Photos of every joint and run.
2
Findings + quote.
Plain-language report of what's wrong with your ducts and what each fix costs. Sealing alone vs. partial replace vs. full redesign.
3
Seal, repair, insulate.
Mastic on every joint. Damaged duct replaced. R-8 wrap restored or upgraded. Sheet metal fabricated where needed.
4
Re-balance and verify.
Airflow re-measured at every register. Dampers adjusted. Before/after report delivered with photos.
Frequently asked
Ductwork questions, answered.
Why does duct sealing matter so much in the desert?
Mesilla Valley attics regularly hit 140 to 150°F in July. A leaky duct in that environment dumps the cooled air you paid for into the attic and pulls 150°F attic air back into the supply or return side. Sealing leaky ducts is one of the highest-ROI improvements you can make to a Las Cruces home, and it's almost always cheaper than replacing the AC.
Should ducts be in the attic at all?
Ideally not, but most existing homes around here were built that way. Where we can re-route ducts into conditioned space, a chase, a soffit, a sealed and conditioned attic, we do. Where we can't, the next best thing is mastic-sealed joints and R-8 minimum insulation. Done right, it's not as good as conditioned space but it's a different planet from where most homes start.
Do you do whole-attic insulation too?
Yes. Blown-in cellulose or fiberglass to current Doña Ana County code (R-38 minimum). We typically pair it with duct sealing because the two attack the same energy-loss path and the marginal cost of doing both at once is small.
Can you fix uneven cooling between rooms?
Yes. Uneven room temperatures are almost always a duct sizing, run length, or static pressure problem, not the AC itself. We measure airflow at each register, identify the choke point (usually an undersized return or a kinked flex duct), and re-duct, re-balance, or both.
How long does a duct project take?
Sealing-only projects are typically a one-day job. Partial re-ducting runs 1 to 2 days. Full system redesign with new trunks and re-routing into conditioned space can be 3 to 5 days. We give you a written timeline with the quote.
Does this work for adobe and mobile homes?
Yes. Adobe homes often have non-standard ductwork and tight access. Mobile homes have under-floor crossover ducts that are notorious for falling apart. Both are routine work for us, we have the custom sheet metal and the access tools to handle them.
