Power companies can adjust your smart thermostat remotely to prevent outages
Power companies can and do adjust smart thermostats remotely to prevent outages. This is a common practice that has been incentivized by energy companies to reduce the strain on the power grid during extreme weather. For example, after a devastating winter storm in Texas in 2021, power companies initiated programs that paid consumers a flat rate and an annual fee in exchange for permission to raise the temperature on their thermostats during "conservation events".
The smart grid senses the increase in demand for power and makes adjustments as needed to prevent outages. Benefits of the smart grid include more efficient transmission of electricity, quicker restoration of electricity after power disturbances, reduced operations and management costs, and ultimately lower power costs for consumers. During the summer of 2021, many homeowners in Texas complained that their thermostats had been turned up remotely, making their homes uncomfortably warm.
Smart meters show how much electricity is being used and the current cost, helping homeowners determine how to set the thermostat during peak times when electricity is most expensive. This can help consumers save money and potentially help save their local area's power grid.
However, some consumers have expressed frustration with being forced to participate in energy-saving programs, feeling that they should have full control over their thermostat settings. It is important to note that participation in these programs is often incentivized and voluntary, and consumers can usually opt-out or change their temperature back if they are unsatisfied.

The smart grid senses demand for power and adjusts to prevent outages
The electric company can adjust your cooling system remotely, which is a common practice that may become more widespread in the future. This is achieved through a smart grid, which is an electricity network that uses digital technologies, sensors, and software to balance electricity supply and demand in real time.
Smart grids can sense an increase in demand for power and make adjustments to prevent outages. They achieve this through a constant stream of data, allowing them to instantly adjust the supply to meet real-time demand. This helps to correct any imbalances between supply and demand, reducing the likelihood of blackouts.
During heatwaves, as temperatures rise and air conditioners are turned on, the smart grid's sensors detect this increased demand for power. The grid then adjusts the supply of electricity to prevent outages and maintain a stable frequency. This is particularly important during periods of extreme weather, which is one of the main causes of power outages.
Smart grids offer several benefits, including more efficient transmission of electricity, quicker restoration after disturbances, and reduced operational costs for utilities, leading to lower power costs for consumers. They also help integrate renewable energy systems and improve security. Additionally, smart meters in homes allow consumers to monitor their energy usage and costs, enabling them to make informed decisions about their energy consumption during peak times.
Overall, the smart grid's ability to sense and adjust to demand fluctuations helps prevent outages and ensures a more reliable and efficient power supply.

A power surge can damage your cooling system
Power surges can cause a host of problems for your cooling system, as well as other electrical devices in your home. A power surge is a sudden increase in voltage, which can be caused by lightning strikes, utility grid malfunctions, or even household appliances cycling on and off.
Lightning strikes are the most common and well-known cause of power surges, and they can be extremely damaging to electrical components. However, smaller, daily surges from local power plants, downed lines, maintenance, and nearby factories can also cause issues. These smaller surges can lead to instantaneous damage or slowly wear down your cooling system over time, even if there are no obvious signs of damage.
During a power surge, the electrical energy may heat up the electrical windings and burn up the wires, especially in the compressor motor, which consists of numerous wires that transform electrical energy into kinetic energy. The control board, or the "brain" of the cooling system, can also be fried, preventing it from communicating with your thermostat and rendering it unable to heat or cool your home correctly.
Other issues that can arise from power surges include faulty wiring, damaged capacitors or relays, frequent tripping of circuit breakers, strange noises, and unusual smells. To protect your cooling system from power surges, you can invest in a whole-home surge protector, which will absorb any extra power created during a surge and prevent it from damaging your cooling system's components. It is also recommended to consult a professional electrician to determine the appropriate surge protection solution for your specific setup.

The size of your cooling system should be matched to your home size
Heating and cooling account for up to 48% of home energy consumption, according to the Department of Energy. Therefore, it is important to ensure that your cooling system is matched to your home size to avoid unnecessary costs.
Firstly, it is important to calculate your home's square footage by measuring the length and width of each room. Then, multiply this number by 20 to get a rough estimate of the BTUs (British Thermal Units) required. Every 12,000 BTUs is equivalent to 1 ton. For instance, a 12,000 BTU unit is suitable for a 400 to 600-square-foot space.
However, bigger is not always better when it comes to cooling systems. If your system is too large, it will engage in "short cycling", turning on and off frequently and cooling your home too quickly without adequately removing humidity from the air. This leads to an uncomfortable environment with uneven temperatures, drafts, and humidity issues. Short cycling also wastes energy, increases wear and tear on the unit, and reduces its lifespan. Conversely, a system that is too small will run more often than it should, also increasing energy costs and reducing its longevity.
To ensure you select the most suitable cooling system for your home, it is recommended to consult a professional for a more precise assessment. They will take into account factors such as room volumes, insulation, and air leakage to determine the appropriate cooling solution.
Additionally, consider combining central heating and cooling systems with space heating or cooling appliances. For example, you can use a central system for the main living areas and supplement it with electric space heaters for individual rooms. This allows for greater flexibility, depending on your climate and the thermal performance of your home.
Furthermore, regular maintenance is crucial to ensure your cooling system operates efficiently and lasts longer. Keep the system clean, store window units in a dry area during winter, and have a professional technician inspect the unit periodically.
By matching your cooling system to your home size and maintaining it properly, you can achieve a comfortable indoor environment while optimising energy efficiency and reducing costs.

The climate you live in will determine the effectiveness of your cooling system
The size of your home is also a factor in the effectiveness of your cooling system. If your system is too big, it will cycle on and off constantly in an energy-wasting process called "short cycling". Conversely, if it is too small, it will have to run more often than it should.
There are several types of cooling systems to choose from. Central cooling options include air conditioners or evaporative coolers, while space cooling options include fans, portable air conditioners, and evaporative coolers. Reverse cycle air conditioners are the most energy-efficient heater and cooler of all types, irrespective of fuel source. They use electricity to warm your home in winter and cool it in summer. An air-conditioner is a type of heat pump. In heating mode, the system absorbs heat from the outside air and distributes it around the room. In cooling mode, it absorbs heat from the indoor air and releases it outside.
If you are looking to save money on your energy bill, start with your thermostat. The Department of Energy estimates savings of about 1% for each degree of thermostat adjustment per 8 hours. You can also consider upgrading your thermostat model to a programmable or smart thermostat. These thermostats sync with smartphones and tablets so you can control them from anywhere and set heating and cooling schedules.
