4 Ways to Synch Up Your Home HVAC System to Smart Devices

After a decade of the smartphone, you can now add the new element of smart houses to your modern lifestyle. If you’re lucky enough to have both, then you can make your life even simpler by syncing your home to your device.

One of the main reasons you would want to do this is to add a little comfort in your home. Now, you can connect your smart thermostat to your smartphone so that when you walk in the door after a long day at work, your home is already at an ideal temperature for your comfort.

With the right app, you can easily sync your home HVAC system to your smartphone and never worry about coming home to stifling heat in the summer or freezing cold in the winter. With these four apps, you can control your home environment from anywhere so that your home will be perfect every time you return.

 

Ecobee

The Ecobee app provides an easy way to control your HVAC smart thermostat. The app can be used with any device with ease. Wireless temperature sensors can also be installed, which can track the temperature of different zones within your house. With these sensors, you can identify areas of the home that tend to be cooler or hotter than the rest of the house and make the necessary adjustments so you have an even temperature throughout. The app is free and can be used from both Android and Apple devices.

 

Nest

The Nest app comes with two different options: the Nest Learning Thermostat and the Nest Thermostat E, both of which can be used on either Android or Apple devices. These apps not only easily manage your HVAC system but can apply energy saving techniques that can be adjusted from any location. In addition to managing your system, you can also manage your bills at the same time.

 

House Wise

How does saving 20% on heating and cooling energy costs sound? House Wise is an Energy Star certified comfort management device. They provide features that extend beyond your traditional “smart” device.” In fact, this device allows for access control from almost anywhere through Wi-fi. Users can also pull energy reports from any tablet or mobile device. Stayed informed, save money, and reduce your footprint with custom energy tips given right from the device itself. House Wise truly gives new meaning to the word “smart device” by setting the standard for other comfort management devices to follow.

 

Google Home

To control your system from inside your home, you can use the Google Home app. This is a smart speaker that sits in your home and responds to your voice commands. Google Home works through Google’s personal assistant. Users need only start by saying “Okay Google,” followed by their specific instructions and the device will take it from there.

You can use Google Home along with a smart thermostat or any of the other smartphone apps to gain complete control of your home environment.

 

So, whether you have just had solar power installation in Solano or you’re just looking for a simple way to control your HVAC system and maintain a consistent comfort level in your home, any one of these apps will always give you the perfect environment to come home to.

Stay Ahead Of The Change With A-1 Guaranteed

Undoubtedly, one of the most important resources we consume as humans is energy. So many things depend on it to power equipment, heat our homes, and keep the world running. Over the years, the term “clean energy” has been thrown around countless times, and it has built up more and more momentum. Clean energy is collected from renewable resources, which is the opposite of the type of energy we use now, which is fossil fuels. Eliminating the use of fossil fuels means homes will no longer be heated by gas, which is what California plans to do by the year 2045.

The Goal

In September of 2018, Governor of California Jerry Brown signed a law that would require California to harvest 100 percent of its electricity from wind power, solar power, and hydropower by 2045. This change is one of many that have been occurring around the world to combat climate change. The new law gives California the most extensive goals for clean energy of any state in the U.S., making it the leader in climate conservation efforts.

What It Means for Gas Heating

Switching from fossil fuels to clean energy means much will change when it comes to the appliances that currently run on those fuels. Heating appliances that use fossil fuels, including natural gas, will change to systems that produce heat electrically.

If this has you wondering how you can plan for new electric heating and air conditioning, the  Electrification Professionals at A-1 Guaranteed & Air Conditioning, Inc. are prepared to show you new and exciting ways to heat and cool your home.

What You Can Do to Prepare

If you need a new system, consider not replacing it with yet another gas furnace.  Let us make your home more comfortable than ever using a clean energy, energy-efficient system using mini heat pump technology.  In addition, most of the costs can be offset with just a few solar panels.

As electrification is adopted, the gas companies will need to spread their operating and maintenance cost to the ever depleting consumer base of their product resulting in gas prices potentially exploding four to five times from today’s rates over the next ten to twenty years.

With these changes on the horizon, Californians have been given the exciting opportunity to spearhead the clean energy movement. Finding heating and air conditioning professionals who are ready for the change may seem impossible , but A-1 Guaranteed is leading the challenge and staying ahead of the curve as the first in residential electrification. We can help you embrace the change!

California taking the initiative and moving forward with this clean energy project will no doubt have its ups and downs. Eliminating fossil fuels will prove beneficial to the environment and to us, but consumers must start planning now. It is important to stay ahead of this change so we’re not caught off guard or waiting until the last minute to get everything squared away.

Contact our experts at A-1 Guaranteed today to learn how we can help you get ahead of the game and make the change to clean energy for your home!

Heat Pump Water Heaters: How They Work and Help You Save Money

The Benefits of Heat Pump Water Heaters

What Is a Heat Pump Water Heater?

Known in the trade as hybrid electric hot water.  Heat pump water heaters use electricity to move heat from one place to another instead of burning gas and creating carbon. They work much like the refrigerator in your home only in reverse. A small compressor – a fan – and a heat exchanger all work together to squeeze the heat out of almost any temperature air and transfer it to the water.

 

Benefits of Heat Pump Water Heaters?

This system uses a fraction of the energy of Traditional gas water heating technology.  In addition to being quiet and clean to operate, nearly all operating costs can be offset with just a few solar panels.  Water usage doesn’t have to change, still allowing you to take all the showers, washing dishes and laundry as you have in the past, but with these units; it’s all done for a fraction of the cost you paid before.  Another benefit of a heat pump water heater is that it doesn’t produce carbon, helping the environment.

In most cases, a standard 40-gallon water heater would be replaced with a 65 or 80-gallon hybrid electric water heater.  Since they use such a minimal amount of energy, the water heats over a long period of time (usually at night when rates are lower) making it available when you need it, even if you have an extra load of dishes to do.

Advanced Solar Electric Strategy is another option available to you which provides a reserve power mode.  An example of when this function would be useful is if you are expecting guests and will need more hot water than normal.  You can set the programming from heat pump to hybrid, automatically optimizing hot water production. When the guests leave, simply set it back to heat pump for ultimate performance.

The Energy Efficiency of these units is measured in coefficient of performance (also referred to as COP). The COP on most units are around 3.4 to 3.7, meaning for $1.00 worth of electricity you can make $3.40 to $3.70 worth of hot water.  Compare that to even the most efficient tankless water heater at .98% efficiency where you get $.98 of hot water for every $1.00 of gas.

 

Considerations for Installing a Heat Pump Water Heater

There are some modifications required for installation but generally the cost is about the same as an efficient gas tankless system.  If there is space in your electrical panel and garage (or wherever your existing unit is) you can likely have one installed. Heat pump water heaters are a great investment for most homeowners.  If you’re looking to save money on your utility bills and reduce unnecessary carbon production, consider installing a heat pump water heater in your home today!

How to Get Rid of That Stubborn Musty Smell in Your Home

Removing Mold and Must from Your Home

If you’ve noticed a musty smell in your home, spending time indoors might not sound too appealing. A musty smell is usually a sign of mold or mildew, which can be hazardous to your health, including respiratory diseases, throat irritation, stuffy eyes and nose, and even skin irritation. You should call a professional to help you find the root cause of the smell, so you can get your home smelling like normal as soon as possible. In the meantime, open plenty of windows so you and your family can breathe easier. Learn more about how to get rid of musty smells.

Step 1: Find the Source of the Problem

A musty smell is a good indication that you have some excess moisture around your home. This may be caused by a leak in your heating or plumbing system, problems with the foundation of your home, or a leak in your roof. Have a professional help you identify the source of the problem by looking for signs of water damage around your home. Once the source has been identified, you can start solving the problem and stopping the flow of moisture. Depending on the extent of the leak, this may include repairs to your home’s HVAC and plumbing systems or the foundation or roof of your home.

Step 2: Get Rid of Infected Material

Once you’ve located the leak source, you’ll need to get rid of everything that’s been infected, which may include drywall, carpet, clothes and other items that can absorb water. If these items and materials are covered in mold, they probably need to be thrown away. You can also start putting fans in the room, leaving the windows open and using some air freshener for some much-needed relief. Avoid spending time in confined areas where the mold has spread and remember to wear a face mask. Removing damaged items and repairing the leak is usually best left to the professionals.

Step 3: Treat and Deodorize Your Home

Finally, it’s time to deodorize your home, so you can get rid of that musty smell once and for all. An air quality professional will help you treat the infected areas, usually with special chemicals. Many treatment solutions usually include boric acid, hydrogen peroxide, and vinegar. These ingredients are effective when it comes to killing and treating mold spores.

Many professionals will also use an electronic air cleaner to purify the air, helping you and your loved ones breathe easy as soon as possible. Musty smells can also linger in your home’s ductwork after a mold outbreak. At A-1 Guaranteed, we’ll also install deodorizers in your ductwork, completely eliminating these smells from your home. It’s also a good idea to setup UV lights around the infected area. These lights are designed to kill and control the germs found in mold, quickly disinfecting your home without damaging the interior.

Once you’ve treated and deodorized your home, you can start putting the space back together. You may need to re-carpet some areas, repair a patch of drywall, or buy some new clothes.

No one should have to live with musty smells. You and your loved ones deserve to breathe easy, especially when you’re hanging out in the comfort of your own home. Stop mold and mildew in their tracks and call the professionals at A-1 Guaranteed today for all things HVAC in Contra Costa.
