QuietCool Whole House Fans in Longmont, CO
Colorado evenings cool off fast. A whole house fan lets you use that free, dry air to cool the whole home and give the air conditioner the night off.
Why Whole House Fans Make So Much Sense in Longmont
If you have ever stepped outside on a July evening in Longmont and noticed it was cooler than your living room, you already understand the idea behind a whole house fan. Our dry climate and altitude mean temperatures drop sharply after sunset, even after the hottest days. A whole house fan turns that free, cool air into whole-home comfort.
The fan mounts in the attic and connects to a ceiling grille in a hallway or central room. Open a few windows, turn it on, and it pulls fresh outside air through every room while pushing the hot, stale air trapped in the attic out through the roof vents. In minutes the house feels fresher, the attic stops radiating heat down into the bedrooms, and the air conditioner can stay off through the evening and overnight.
M&M Heating, Cooling, Plumbing & Electrical installs QuietCool whole house fans, which use insulated ducting and a motor suspended away from the ceiling grille so you get the airflow without the roar of an old-style attic fan. Because a whole house fan uses only a fraction of the electricity of an air conditioner, homeowners who use one consistently often see a real drop in summer cooling costs. We will not quote a percentage, because it depends on how you use it, but the math works in your favor on most Front Range homes.
Our licensed, insured technicians handle the attic work, the electrical connection and the grille installation cleanly, and we provide free estimates. A whole house fan pairs well with a right-sized air conditioner or on its own in homes without central cooling.
What a QuietCool Whole House Fan Does for Your Home
More than a cooler house. Here is what homeowners notice first.
Lower Summer Cooling Costs
A whole house fan draws a small fraction of the power an air conditioner needs. Every evening and night it runs instead of the AC is money that stays in your pocket.
Fresh Air, Not Recirculated Air
Instead of cycling the same air through the house, a whole house fan replaces it with outdoor air several times an hour, flushing out cooking odors, pet smells, smoke and stuffiness.
A Cooler Attic and Cooler Bedrooms
Attics along the Front Range get brutally hot and radiate that heat down through the ceiling well into the night. Venting it out makes upstairs rooms noticeably more comfortable for sleeping.
Quiet Enough to Run While You Sleep
QuietCool's ducted design places the motor away from the grille and dampens vibration, so the fan does a big job without the noise that gave older attic fans a bad name.
Less Wear on the Air Conditioner
Every hour the AC does not run is an hour of wear it does not accumulate. Pairing a whole house fan with central air often means fewer repairs and a longer-lasting system.
Simple Controls, Multiple Speeds
Wall switches, timers and smart controls let you run a gentle overnight setting or a quick high-speed flush when you get home. We set it up the way you want to use it.
The M&M Difference
One company for the fan, the electrical and the rest of your cooling system.
HVAC and Electrical Under One Roof
A whole house fan needs a properly sized unit, attic venting and a safe electrical circuit. Our team handles all three, so there is no second contractor to coordinate.
Sized for Your Home
Fan capacity has to match your square footage and attic ventilation or it will not perform. We measure first and recommend the QuietCool model that fits.
Free Estimates, Upfront Pricing
You will know the full installed cost before any work begins, with no surprises when the job is done.
Family-Owned Since 1996
M&M has served Longmont and the Front Range for nearly 30 years. We install systems we would put in our own homes, and we stand behind them.
Our 4-Step Process

Free In-Home Estimate
We measure the home, inspect the attic and its venting, and confirm the best location for the ceiling grille. You get upfront pricing on the right-sized QuietCool model.
Attic Prep and Venting Check
A whole house fan needs enough attic exhaust area to move air out. We verify existing vents and recommend additions if needed so the fan performs as designed.

Our technicians mount the fan, run the insulated duct, install the grille and damper, and wire the controls on a properly protected circuit.
Walkthrough
We show you which windows to open, how to use the speeds and timer, and how to get the most cooling from the evening air. Then you enjoy a cooler house.
Whole House Fan Questions from Longmont Homeowners
How is a whole house fan different from an attic fan?
An attic fan only ventilates the attic space. A whole house fan pulls air through the living space itself, bringing fresh outdoor air in through open windows and pushing hot indoor and attic air out through the roof vents. It cools the people, not just the rafters, and it works any time the outside air is cooler than the inside.
When should I run it?
Evenings, overnight and early mornings, whenever the outdoor temperature is lower than indoors. On the Front Range that is most summer nights. Open a few windows, run the fan to flush the house, then close up in the morning to trap the cool air. On the hottest afternoons, let the air conditioner take over.
Will it replace my air conditioner?
For some Longmont homes, yes, especially those with good shade and homeowners who are comfortable with a few warm afternoons. For most, it works alongside the AC: the fan handles evenings and nights, the air conditioner handles the peak heat. Either way you run the AC far less than you would otherwise.
Is a QuietCool fan really quiet?
Much quieter than the belt-driven attic fans many people remember. QuietCool suspends the motor in the attic and connects it to the ceiling grille with a length of insulated duct, which isolates vibration and noise. On low speed it is quiet enough to run through the night without disturbing sleep.
Does my attic need extra vents?
Sometimes. The fan has to be able to push air out as fast as it pulls it in, so attic exhaust area matters. We check your existing ridge, gable and soffit vents during the estimate and let you know if more ventilation is needed. Skipping this step is the most common reason a whole house fan underperforms.
How much will I save on cooling?
It depends on your home, how much you run the AC today and how consistently you use the fan. What we can say is that a whole house fan uses a small fraction of the electricity of an air conditioner, so every hour it replaces is a meaningful savings. We are glad to talk through realistic expectations for your house during the estimate.
