Cooling
QuietCool Whole-House & Attic Fans
Efficient. Powerful. Whisper-quiet. Purpose-built cooling for the desert heat.
QuietCool attic fans pull hot air out of your attic, helping lower indoor temperatures, reduce A/C use, and extend the life of your roof. Designed for energy efficiency and nearly silent operation, they are the smart solution for a cooler, more comfortable home, especially in the desert heat.
Southern Utah is close to ideal territory for this equipment: our attics bake all day, and our evenings cool off fast. The right fan strategy uses both.
Attic fans: stop storing heat over your ceiling
On a July afternoon a Washington County attic can run far hotter than the air outside, and that heat radiates down into your living space all evening. A solar attic fan exhausts that super-heated air all day at zero operating cost, taking load off your A/C and stress off your shingles.
Whole-house fans: use the desert evening
When the sun drops and the temperature falls, a QuietCool whole-house fan pulls that cool outside air in through open windows and pushes the day's heat out through the attic. Minutes of runtime can swap the air in the whole house, and the system is quiet enough to run while you sleep.
A garage fan does the same job for the hottest room most homes have, so a west-facing garage stops radiating heat into the rooms beside it.
The QuietCool lineup
Solar Attic Fan
Solar-powered attic fan that exhausts super-heated attic air all day at zero operating cost. Attics here can top 150°F in July.
Whole House Fan
Pulls cool evening air through open windows and pushes hot air out through the attic. Made for desert nights when it drops 30 degrees after sunset.
Garage Fan
Exhausts trapped heat from the garage so it stops radiating into the rooms next to it. A big comfort upgrade for west-facing garages.

Common questions
How much does skylight installation cost in St. George?
It depends on the model, roof type, and interior finish work, so we quote every project after a free in-home consultation. You get a clear, flat quote before any work starts. Call us at (435) 772-6137 for current pricing on any accessory or add-on.
Do you offer a warranty on installation?
Yes. Our VELUX skylight installations are backed by a 10-year installation warranty, on top of the manufacturer's product warranty on the unit itself.
Is there still a federal tax credit for solar-powered skylights?
No. The 30% federal Residential Clean Energy Credit ended for installations completed after December 31, 2025, so new installations no longer qualify. If any state or utility incentives apply to your project, we will flag them during your consultation.
Do whole-house fans actually work in the desert?
Yes, and Southern Utah is close to ideal for them. Desert evenings cool off fast, and a QuietCool whole-house fan pulls that cool air through the house while pushing the day's heat out of the attic, cutting how long your A/C has to run.
