Attic Ventilation in Granada Hills
A balanced system — not just adding a vent. We design complete intake-and-exhaust ventilation that lets trapped attic heat escape, protecting your roof, HVAC, and comfort.
Why Attic Ventilation Matters in Granada Hills
Over 90% of Southern California homes don't have properly balanced attic ventilation. Attics here get extremely hot — commonly 140 to 150 degrees on a warm summer day, and sometimes 160 degrees or higher. The goal isn't to make the attic cold; it's to let trapped heat escape instead of building up and baking the structure all day long.
Your HVAC Is Working Inside an Oven
Most people don't realize their air conditioning system is often located inside the attic. That means your HVAC is trying to create cold air while sitting in a superheated space. Even insulated ductwork only has a thin layer of insulation, so when the attic gets excessively hot the ductwork absorbs heat and the system has to work much harder — shortening HVAC lifespan, reducing efficiency, and increasing energy bills.
Poor Ventilation Also Damages Roofs
Improper attic ventilation can shorten the lifespan of the roof itself. Before starting this company I worked in roofing for many years and saw homes where a poorly ventilated section was already failing after roughly 15 years, while the properly ventilated section still had plenty of life left. The trapped heat was literally baking the shingles from underneath.
Balancedintake & exhaust
A Complete Ventilation System, Not Just Vents
Intake & Exhaust Together
Ventilation only works with intake low on the roof and exhaust high on the roof. Most contractors add only upper vents and ignore the intake — we balance both so the attic can actually breathe.
Ridge & Roof Vents
Ridge vents, static roof vents, eave ventilation, and gable vents — selected and combined correctly for your specific roof rather than randomly added.
Solar & Powered Fans
Solar attic fans, powered attic fans, and QuietCool whole-house systems. Some systems shouldn't be mixed, so we design what actually fits your home.
Baffles & Airflow Channels
Blocked intake vents are one of the most common mistakes we see. We install baffles to create an air channel from the intake vents while still letting the attic floor be properly insulated.
Ventilation Corrections
We replace improperly installed ventilation, correct poorly balanced systems, close off incorrect vents, and reconfigure attic airflow pathways.
Quick Summary
90%+ of Southern California homes lack proper attic ventilation, and improper systems can trap heat reaching 150–160+ degrees. Done right, it improves comfort, lowers energy bills, helps insulation perform, and extends the life of your roof and HVAC.
How We Approach Attic Ventilation
A complete system designed for your house — not a one-size-fits-all fan.
Inspect the Whole System
We evaluate your existing intake and exhaust, check for blocked vents, and look at attic temperature, insulation, and how your HVAC is affected.
Design a Balanced Plan
We determine the right mix of intake vents, ridge or static vents, gable vents, solar or powered fans, and QuietCool — choosing systems that work together rather than fight each other.
Install & Correct
We install the ventilation and add baffles where needed so airflow stays open while the attic floor remains properly insulated, correcting any improper existing work.
Confirm It Breathes
We've seen attics go from unbearable oven-like conditions to dramatically cooler within 20 to 30 minutes once proper ventilation is in place.

What Granada Hills Homeowners Say
"Luke told me that the house will stay cooler in the summer and warmer in the winter. The effect has been phenomenal. My AC used to kick in at 1:00 PM in the hot summer days and now it only comes on at 4:00PM and stays on for seven minutes and turns off! The effect has been unbelievable."
"Luke at Hunter's Insulation was awesome! Super knowledgeable and easy to work with. He explained the best insulation options and helped me make the right choice for my home. Really appreciate the honest advice—highly recommend!"
"Luke and his team did a great job. They arrived on time, finished early and walked me thru the job when they were done. I highly recommend them for any insulation project. Don't be afraid to ask questions."
