"You actually answer the phone."
Reported the upstairs bedroom dropping roughly 10°F within twenty minutes of switching the fan on — a typical real-world result for a properly sized whole-house fan on a cool evening.
Chose Centric Air over QA Deluxe and competitors specifically for the German motor engineering, the HVI-916 certified airflow rating, and the customer service. Installed in a 1,200 sq ft, 115-year-old home.
Likes walking the dog at night with the windows open and the fan running. The detail he keeps noticing: at 11pm, neighbors' A/C units are still cycling on — and his isn't.
A short, repeatable line that captures the Centric Air positioning better than any of our marketing copy does.
"The Mercedes of whole house fans at a VW price."
A short post-install reaction that captures the "should have done this years ago" pattern we hear most often from QA Deluxe owners.
"Why didn't we do this sooner?!?!"
DIY-installed the QA Deluxe 5500 with the wired remote in under two hours in a 2,800 sq ft, two-story home. Added rockwool insulation around the damper to dampen sound through vaulted ceilings — a thoughtful detail that shows what an attentive owner can do with the platform.
What surprised them: getting a Sunday response from the manufacturer when they had a question, and the 10-year motor warranty backing a value-priced fan.
Running the fan a few hours after sunset and again early morning brought the home down to the mid-60s. Skipped A/C entirely through mid-summer.
"10/10, should have done this years ago!"
A previously stuffy home turned comfortable after running the fan a few evenings — quiet operation, cool air pulled through every room. Her husband completed the install in a few hours using the included instructions.
"My gosh — it's fantastic."
An experienced homeowner who had previously installed a different whole-house fan praised the easy-to-follow wiring diagram, the robust included conduit, and the built-in timer functionality.
"The conduit they provide is of very high quality."
After a year of strong performance a blade and bracket malfunctioned. The owner contacted the seller and received an immediate replacement — highly recommended the seller for handling the issue on the spot.
"Amazing service, solid product."
Beyond customer reviews, both brands carry independent certifications that you can verify with the issuing bodies directly.
Every published CFM rating on both Centric Air and QA Deluxe is independently tested and certified under California Energy Commission Title 24 — no self-reported airflow numbers.
CFM specifications follow the Home Ventilating Institute's HVI-916 standard — the same industry-standard test method that lets you compare apples-to-apples across brands.
Nineteen years of California-based manufacturing across both brand lines, with motor warranties of 15 years (Centric Air) and 10 years (QA Deluxe).
