What is a Whole House Fan, and Do I Need One?
A whole house fan is a powerful fan installed in your home’s ceiling. It is used to circulate air throughout your home, providing natural ventilation and cooling. Whole-house fans are a great way to save money on your energy bills by helping to reduce the need for air conditioning.
How Does a Whole-House Fan Work?
A whole house fan works by drawing in cool air from outside and expelling hot air from inside your home. When the fan is turned on, it creates a powerful airflow that moves the air. The hot air inside your home is then expelled through the attic vents.
Benefits of Using a Whole-House Fan
There are many benefits to using a whole-house fan, including the following:
- Saves money on energy bills. Whole house fans can help reduce the need for air conditioning, saving you money on your energy bills.
- Improves indoor air quality. Whole house fans can help to improve indoor air quality by circulating fresh air throughout your home. This can help to reduce the levels of pollutants and allergens in your home.
- Increases comfort. Whole house fans can help to increase comfort in your home by cooling your home naturally.
- Extends the life of your HVAC system. By using a whole house fan to cool your home on hot days, you can extend the life of your HVAC system because it won’t have to work as hard.
It’s best to have our professionals install a whole-house fan for you to ensure it’s done correctly and to make sure you’ll receive the maximum benefit from using it.
When to Use a Whole-House Fan
Whole house fans are most effective on hot, dry days when the outside temperature is cooler than the inside temperature of your home. You should not use a whole house fan on hot, humid days, as this can actually make your home feel more humid. Any time you feel like the air in your home is stagnant, stale, or isn’t circulating on its own to the extent that you’d like it to, you can use the fan to help.
How to Choose a Whole-House Fan
When choosing a whole-house fan, there are a few things that you should keep in mind, including:
- The size of your home. The size of your whole-house fan should be based on the size of your home. A larger fan will be able to move more air, which is important for larger homes.
- The climate you live in. If you live in a hot climate, you will need a whole-house fan that can move a lot of air. If you live in a cooler climate, you may not need as large of a fan.
- The type of attic you have. If you have an unvented attic, you will need a whole-house fan that has a built-in attic fan. This will help to prevent moisture buildup in your attic, which can lead to mold and mildew growth.
Maintaining a Whole-House Fan
These fans require very little maintenance. However, it is important to clean the fan blades and the fan housing on a regular basis. Regular check-ups and preventative maintenance can also help keep your fan in top shape. Have the fan system inspected by an A-1 Guaranteed pro on a regular basis to ensure that it is in good working condition.

Think You Don’t Need a Bathroom Fan? Think Again! Here’s Why They are So Important
Many people don’t think much about their bathroom exhaust fans. However, they are an important part of any bathroom. These fans help remove moisture from the air, which can help prevent mold and mildew growth. They can freshen the air and remove many different offensive odors and germs.
Why Bathroom Fans are So Important
Moisture is a major problem in bathrooms. When you take a shower or bath, the water vapor in the air can condense on the walls and ceiling, creating a breeding ground for mold and mildew. These organisms can cause respiratory problems, allergies, and other health issues.
Odors are another problem in bathrooms. All kinds of bodily wastes and fluids can produce strong odors that can permeate the entire house. Bathroom exhaust fans help to remove these odors from the air, which can help to keep your home smelling fresh and clean.
Bathroom exhaust fans can also help to improve indoor air quality. Dust, pollen, and other pollutants can enter your home through the bathroom vent. Bathroom exhaust fans help to remove these pollutants from the air, which can help to improve your respiratory health.
Choosing the Right Bathroom Exhaust Fan
When choosing a bathroom exhaust fan, there are a few things you need to consider. The size of the fan should be based on the size of the bathroom. The fan should also be powerful enough to remove moisture and odors from the air. You also need to choose a fan that is quiet and energy-efficient.
Here are some tips for choosing a bathroom exhaust fan:
- Choose a fan that is the right size for your bathroom. The fan should be able to move enough air to ventilate the space properly.
- Choose a fan that is energy-efficient. Look for a fan with an Energy Star label.
- Choose a fan that is quiet. You don’t want the fan to be so loud that it disturbs you or your family.
- Choose a fan that is easy to install. Some fans are more difficult to install than others. Choose a fan you can install yourself, or a professional can install easily.
Bathroom exhaust fans are an important investment in your home. They can help to improve your health and the health of your family. Choose a fan that is the right size, powerful enough and quiet. And make sure it is easy to install. With a little planning, you can find the perfect bathroom exhaust fan for your home.

California is Saying Goodbye Gas, Hello Electric!
Electric technology is constantly evolving, and gas appliances are falling out of favor with consumers as a result. Electric appliances are now better performing and more energy efficient than they have ever been, while gas ranges and furnaces have seen little to no innovation in decades. The gas industry has actively resisted efficiency standards increases, which has only accelerated the decline of gas appliances.
The LED lightbulb is a great example of this steady innovation: It’s now over five times more energy-efficient than the incandescent bulb. Most electric devices have also seen significant efficiency improvements, making them a more sustainable choice for consumers.
The Department of Energy plans to raise energy efficiency standards for appliances, saving consumers billions of dollars on future utility bills. As our electricity becomes cleaner, emissions from electric appliances are decreasing. Several states have passed laws requiring electricity to be generated from 100% renewable sources in the near future, and renewables make up the majority of planned new electricity generation.
Governments are increasingly focused on policies that encourage the use of electric appliances in homes and buildings. Many policies proposed for the 2023 legislative session would prioritize building electrification.
Cities are pushing for ordinances that require all-electric new construction, and states have passed building codes requiring all-electric construction for new buildings. In the California Bay Area, gas appliances will no longer be sold, starting with gas water heaters, in 2027.
All of us can be part of this trend toward high-efficiency, modern electric appliances, avoid the increasing costs and negative health and environmental impacts of gas, and help transform our energy systems through our choices in our homes.
Here are some tips on how to electrify your home:
- Start by replacing your gas furnace with an electric heat pump.
- Install solar panels on your roof to generate your own electricity.
- Switch to an electric stovetop and oven.
- Replace your gas water heater with an electric one.
- Install energy-efficient appliances and light bulbs.
- Weatherize your home to reduce energy use.
- Take advantage of government incentives and rebates for energy-efficient improvements.
Make small changes that can make a big difference!
Could Vermont Gas Systems be a Model for the Future?
A new study shows that gas utility plans to rely on alternative fuels are not feasible and that even a modest decrease in the number of consumers who leave the gas system could cause gas rates to quadruple by 2040. Clearly, figuring out how to decarbonize the gas system equitably is a major concern.
Vermont Gas Systems (VGS) is finding ways to use electrification to reduce carbon emissions while maintaining a relevant business. They hope to do this by delivering residential and commercial heating. Could this be a model for other gas utilities to follow as we transition away from fossil fuels?
VGS is working on a number of initiatives geared toward promoting electrification, including:
- Developing a plan to transition its customers to all-electric heating by 2050
- Investing in research and development of new electric heating technologies
- Partnering with local governments and businesses to promote electrification
VGS’s efforts could be a model for other gas utilities as they transition away from fossil fuels. By embracing electrification, VGS can help reduce emissions, save customers money, and create jobs in the clean energy sector. California and other states can use VGS as a great example.

Why is Hiring a Licensed HVAC Contractor Instead of My Friend Important?
It might be tempting to hire your buddy who knows “a bit about HVAC” instead of a licensed contractor. Maybe it’s not easy for you to tell a friend “no” who offers assistance with a heating or cooling issue you’re having. Maybe you just want to save money and think having your friend take a look at things will keep more dollars in your pocket.
Unfortunately, in the long run, this almost never pans out. Not unless your friend is a licensed HVAC contractor!
Top Reasons to Hire a Licensed HVAC Pro, Not Your Friend
There are many reasons for choosing to forego your friend and get a licensed contractor.
1. You’ll Stay Legal
Depending on the task, having someone other than a licensed professional complete your work might be dangerous, costly, and illegal. Some HVAC jobs in California require permits to be pulled and inspections to be completed to be legal.
2. You Will Benefit from their Professional Experience
HVAC units are big investments, and you want someone working on yours who has the knowledge, skills, and experience to get the job done right the first time, every time. It’s far too easy for inexperienced handymen and friends who mean well to cause more damage to a system.
You will save so much time and money in the long run by going with experienced, licensed HVAC technicians in the Bay Area. Good technicians also will help you understand how to properly maintain your unit to keep it running as efficiently and effectively as possible.
3. You’ll Maintain Warranties and Guarantees
If your HVAC system still has a valid warranty, you must ONLY have a licensed professional maintain it, work on it, and repair it to keep that warranty. If the warranty already expired, you can still rest assured that the warranty of the licensed technician covers the work done on your system.
The best technicians will always explain all warranties and how the work they do affects them before they begin working.
4. You will Save Yourself the Grief of Having a Falling Out with Your Friend
So much goodwill begins with one friend really wanting to help another. All too often, something goes wrong, and the friendship is threatened (or ends) because of an argument, a misunderstanding, a lack of knowledge, or a lack of correct HVAC experience.
Don’t risk your relationship with any of your buddies, girlfriends, or pals; leave it all to the best HVAC professionals and save your friendship.
5. You’ll Stay Safe
HVAC systems can be dangerous when they aren’t properly installed or maintained. If improperly handled, they can be fire hazards or emit deadly carbon monoxide into your home. Don’t risk it; call an expert.
6. You’ll Save Money, Even by Hiring a Professional
It happens all too often: One friend tries to help another by performing some HVAC maintenance, but immediately or down the road, something goes wrong. The friend doesn’t know how to fix it, so the owner of the HVAC system calls upon an expert to check things out.
At this point, all warranties have been voided because an unlicensed technician tampered with the HVAC system. So, what would’ve been covered is now the owner’s financial responsibility. Not only that, but the small issue the friend tried to fix is now even more of a problem, costing the owner even more money!
Save yourself time, trouble, money, and grief, and go straight to calling a licensed HVAC contractor for help!
