How to Reduce Your Utility Costs When Spending Time at Home

Save Money on Electricity During COVID-19

If you’re one of the many people that’s been stuck at home throughout the COVID-19 pandemic, you’re probably generating more electricity than you’re used to. Many people have seen their utility bills soar over the course of the pandemic, especially when working from home or helping their kids with online learning. It’s almost impossible to get through one day in quarantine without reaching for an outlet. But increased demand can lead to high bills and outages if the utility company can’t keep up.

Whether you want to lower your monthly expenses or avoid a dreaded blackout, use these tips to reduce energy consumption when working from home:

Unplug Electronics When Not in Use

So many appliances and devices suck up electricity when they’re plugged into the wall. They may have a flashing light or stay connected to the internet, ratcheting up your electric bill. When the battery on your smartphone or laptop is finished charging, unplug the charger.

Let in the Light

Don’t turn on lamps and lights unless you need them. Brighten up the space by working near windows or opening the blinds. Spend a few seconds looking outside to break up all that screen time.

Update Insulation

Regardless of the temperature outside, make sure your home is properly insulated to keep the heat – or cold – inside your home. Summer will be here before we know it and it’s almost time to dust off your A/C. Get a head start by adding a few layers to the walls and ceiling, especially in high traffic areas. Watch out for leaks, drafts, and other poorly-insulated areas to stop the warmth or cool air from slipping between the cracks.

Replace Outdated Filters, Bulbs, and Equipment

Every home needs maintenance. As you spend more time at home, get in the habit of changing out the filter on your HVAC unit to improve air quality. If the filter is dirty or clogged, the system will have to work overtime to push air into your home. Swap out florescent lightbulbs for LEDs and old appliances for energy-efficient models to cut down on usage.

Go Solar

If you’re really looking to save money, consider installing a set of solar panels on your property to generate your own electricity. You won’t have to pay the utility company for every watt you use. They may even pay you for pumping excess power back into the grid. If a crisis or blackout should occur, solar panels will help you keep the lights on when you need them most.

 

The pandemic has transformed our lives in so many ways. Our homes are no longer just for sleeping, waking up, and relaxing after work. They are where many of us spend nearly 100% of our time. Contact A-1 Guaranteed to learn more about saving money on electricity throughout the pandemic.

Why More People are Going Solar During the Pandemic

Take Control of Your Electricity with Solar Energy

2020 was a rough year for many of us, but it turned out to be a good year for solar energy. The International Energy Agency reports that solar energy now makes up a bigger share of all energy production compared to pre-COVID-19. Solar adoptions rates have been on the rise for years as this technology comes down in price and consumers and businesses look for ways to reduce their impact on the environment.

But the pandemic has only accelerated this trend. Find out why solar energy is having a moment.

Saving Money

Millions of people have lost their jobs over the last 12 months, including those in the entertainment, food service, and hospitality industries, and it’s not clear these jobs are coming back any time soon. The unemployment rate is now up to 15%.

For many Americans, going solar has been about saving money. Utility bills can run as high as $100 or more, especially in urban areas and remote regions with little access to electricity. To reduce their expenses, many families have decided to generate their own electricity instead.

To generate solar power, you’ll need to have a professional install a series of solar panels on the roof of your home. These panels are much less expensive than they were just a few years ago. Most homes are compatible with solar panels. The technician will find the spot where the most light comes in to help you generate as much electricity as possible. Once they’re up and running, you don’t have to worry about paying for power. The utility company may even pay you for excess electricity if you pump it back into the grid.

Solar energy has helped millions of Americans save money over the last few years. Many people are quickly taking advantage of this technology as a way of shoring up their finances during this uncertain time.

Changes in Energy Consumption

Fewer people are traveling, and more people are spending time at home. That has changed the way many people use and generate electricity all over the country. Utility companies are used to generating additional power around 6 or 7 PM when most people get home from work. That’s when people start opening the refrigerator, running the A/C or heat, watching TV, making dinner, and washing their clothes. During peak demand, utility companies often swoop in to help make sure there’s enough power to go around, often relying on natural gas and coal-generated fuel, which contribute to climate change.

Now that millions of Americans have started working from home, they aren’t using as much power at the same time. They can spread out these activities throughout the day by doing laundry in the afternoon or preparing dinner ahead of time. This reduces our dependence on big utility companies, so more people can comfortably generate their own electricity at home.

Claiming Energy Independence

There’s no denying it’s been a chaotic year. From the pandemic to major storms and rolling blackouts, many people have been living on edge over the last 12 months.

Considering how much we all depend on electricity, going solar is also about claiming your independence from the utility company and the grid. If a major storm causes a power outage or a global pandemic increases the cost of electricity, you can take control of the situation by generating your own electricity.

With everything in flux, many people have been craving some sense of autonomy. And going solar does just that. It gives people the power to control their destiny in this increasingly unpredictable world.

Do You Have Water Dripping from Your Heat Pump?

Heat pumps are a popular, efficient way to heat your home by transferring heat into the home in the winter and out of your home during the hot summer.  However, even with the highest quality units, it’s possible for them to leak from time to time, and there are a number of factors that can contribute to the issue.

It’s no need for immediate alarm, but a leaking heat pump does need to be addressed by a heat pump repair expert. Ignoring a leak from your heat pump can lead to mold infestation, water damage in your home, and damage to the heat pump itself. Standing water within it can cause electrical issues and further breakdown, as well.

Following are some of the most common causes of heat pump leaks:

A Dirty or Frozen Evaporator Coil

The cold evaporator coil in a heat pump collects condensation from the air, draining it into a pan that then leads to another drain. When this evaporator coil gets dirty, it can cause water to drip onto the ground and malfunction.

During the summer, if refrigerant levels drop to low, ice can actually form on the coils. This not only impairs the cooling process, but it also keeps your heat pump in Contra Costa from working properly. So, what creates the leaking water with frozen evaporator coils? The puddles of water you see are caused by the ice on those coils melting, in this case.

Drain Issues

Most heat pumps use that drain pan mentioned above to collect condensation. However, should this drip pan become clogged with anything from algae to mold to debris, it might overflow and create a puddle near your heat pump. If the condensation pan is set incorrectly or the drain line gets clogged, water will overflow and cause that leak you see. Usually, your pump will automatically shut off before this happens; however, the problem will still need to be addressed by our HVAC experts in Solano before you can run your heat pump again.

A Cracked Overflow Pan

Heat pumps pull humidity out of the air as part of the cooling process – much like air conditioners. This humidity collects on the coils and drips to the overflow pain or drains. Over time, that pan could start to deteriorate or corrode, leading to it cracking. A leak you see could be caused by this cracked pan.

 

Addressing small issues with your heat pump in the Bay Area before they become bigger, more expensive issues is always a good idea.

Is Your Furnace Short Cycling? How to Tell and What to Do

With much of the country facing record-breaking cold temperatures, furnaces from coast to coast are working at capacity – and sometimes over-capacity. Regardless of the time of year, you always want to make sure that your furnace is working efficiently and properly.

One common issue for homeowners is a furnace that is short cycling – also known as overheating. When a furnace short cycles, it kicks off and on frequently with very little time in between.

What Causes a Furnace to Short-Cycle?

There are several things that can cause your heating system to short cycle. Some of these include:

  • A malfunctioning flame sensor or flame rod
  • Dirty furnace filters
  • Heat registers that are blocked
  • Exhaust vents that are blocked
  • A furnace that is too large for your home
  • A thermostat mounted in a bad location

While these issues aren’t the only possible causes of this type of malfunction, they are the most common. Let’s take a deeper look at the issues and find out what to look for.

Malfunctioning Flame Sensor or Rod

If your gas furnace flame shuts off almost immediately after lighting, you may have a bad flame sensor. To find out for sure, remove the cover from the furnace and look for the burner firing. You can also listen for the “whoosh” sound it makes. The inducer motor should run anywhere from 30-60 seconds before the gas fires. If the gas never fires, a sensor could be to blame.

This is because the sensor is designed to recognize when a gas valve has fired; if it doesn’t sense a flame, it will shut off the gas valve to prevent raw gas from flooding your home. Your sensor will need to be replaced – it’s a simple job that our HVAC experts in Napa can do.

A Dirty Furnace Filter

A dirty filter prevents a proper flow of return air into the furnace, which can cause your HVAC system to overheat. If your furnace gets too hot, the switch will shut it down to prevent damage. If you notice that your furnace shuts down after running only for a few minutes, the filter may be blocking that air flow. Fortunately, this is an easy fix, and it doesn’t require any specialty HVAC training: simply change your filter.

Blocked Heat Registers

Heat registers that are blocked don’t let enough air out of the HVAC system – one of the telltale signs that this may be your issue is if the air coming out of your open registers is hotter than normal. When registers are blocked, your furnace can’t disperse enough heat to function properly, causing it to overheat and shut down. Make sure your registers aren’t blocked and you don’t have too many dampers closed on your air ducts.

The Exhaust Vent is Blocked

This issue is one that is particularly dangerous because carbon monoxide could be allowed through the vent. Wild animals and birds building nests, snow, ice, and beehives can block the exhaust flue of your home. If you need help removing an animal, beehive, or other pest, you may want to call an animal control expert for help.

Your Furnace is Too Large

Bigger is not always better when it comes to furnaces. Unfortunately, it’s a common problem, though due to misinformed HVAC installers believing that bigger units will save the customer money. However, when a furnace is too large, it will deliver a large amount of warm air in a short amount of time, reaching the desired temperature quickly, then shut off. What a proper-sized furnace should do, however, is deliver warm air steadily – not in short bursts. Your furnace might be too large for your home, causing short cycling if you notice temperature swings, high heating bills, and frequent on/off cycles. Our experts in HVAC in Vallejo can help you choose the best (and properly sized) furnace for your home.

Your Thermostat is in a Bad Location

Yes, the location of your thermostat matters! If it’s getting warmed up before the rest of your house is, it will cause your furnace to shut off before it should. Your thermostat should never be installed right above a heating register or on the wall of a closet where a furnace is located, for example. With both of these locations, the thermostat will sense more heat quicker than the heat can reach the rest of your house. Simply relocate your thermostat to a central that is away from windows, registers, and furnace closet walls.
