How To Calculate Your Energy Usage

Tuesday, July 11th, 2017

Electricity costs can be significant in Southwest Florida, and if you would like to minimize your utility bills, the best way to start is by calculating your energy usage. Every appliance, light and electronic device has its own electricity requirements, and the first step in calculating your energy usage is determining what that figure is for each device.

Using the Energy Guide Label

Many appliances and electronics, including large appliances like air conditioning systems, have a yellow Energy Guide label that makes determining energy usage simple. For electrical devices, the label will list estimated yearly energy usage in kilowatt-hours, which are the same units used on your electricity bill. To determine a device’s monthly usage, simply divide that number by 12, and to determine its daily usage, divide by 365.

Using Wattage

If no Energy Guide label is present, check the device for a label listing its electrical requirements, which is often found near the electrical cord. Many products will list the device’s wattage. To convert watts to kilowatts, simply divide by 1000. For example, a coffee maker that uses 800 watts would use 0.8 kilowatts of power. To find the kilowatt-hours used by a device, multiply the kilowatt rating by the number of hours the device is used daily. For example, the coffee maker that is rated for 0.8 kilowatts would require 2.4 kilowatt-hours of electricity a day when used for 3 hours.

Using Amperage

Some devices do not list wattage, so it must be calculated by multiplying amperage and voltage. For most devices, the voltage will be 120, though larger appliances may use 220 or 240 volts. A device that uses 5 amps at 120 volts would require 600 watts of power, while one that uses 0.5 amps would require 60 watts. Smaller devices may be rated in milliamps, which must be divided by 1000 to find the amps. Once the wattage is found, the kilowatt hours can be calculated, then simply add all your devices to calculate your total energy usage.

3 Easy Ways to Keep a Lid on Energy Consumption

Tuesday, March 7th, 2017

Keeping utility costs under control in Southwest Florida can be a challenge, especially as peak air conditioning season arrives. By taking a few simple measures to control your energy consumption, however, you can reduce your utility bills, while helping the environment.

Have the Air Conditioning System Serviced

Routine maintenance, such as changing the air filter and cleaning the evaporator and condenser coils, will help the air conditioning system to transfer heat and move air more efficiently. Not only does this reduce energy costs, but it also helps to extend the life of the system. Adding a programmable thermostat and setting it to raise the temperature 5 degrees anytime you are away from home can also lower your energy consumption significantly.

Reduce Heat Gain

Another way to reduce energy usage is by eliminating some of the extra heat produced in your home, making the job of the air conditioner easier. Use shades and blinds during the daytime to block the heat of the sun, and open the windows during cooler periods for natural ventilation and cooling. Avoid using heat-generating appliances like clothes dryers, dishwashers and ovens during the day, and wait until the evening when it is cooler to cook or bathe. When the air conditioning system is installed, place the outdoor unit in a shady location, if possible, or consider adding some shade.

Use Efficient Appliances

Choosing the right appliances and electronics can have a significant impact on your energy costs. When replacing older models, purchase the most efficient versions possible, such as those that are Energy Star-rated. Turn off appliances, lights and electronics when they are not in use, and consider using outlet strips to completely turn off devices that have a continuous power draw, such as televisions and cable boxes. Replace older incandescent light bulbs with energy-efficient CFL or LED models, and turn down your water heater to 120 degrees, instead of the typical 140-degree factory setting.

How Ductless Air Conditioning Systems Save Energy

Tuesday, December 27th, 2016

Thanks to their simple installation process, ductless air conditioning systems are a popular way to add air conditioning to a home that lacks it, or to a new addition. Ductless systems are ideal for spaces like attics and room additions where extending ductwork is impractical. With their unique designs and lack of energy-wasting ductwork, they are also extremely efficient. Here is how ductless air conditioning systems save energy and reduce your cooling costs.

How Does a Ductless Heat Pump Installation Save Energy?

  • No duct losses: Traditional HVAC systems lose up to 30% of energy through leaky or uninsulated ductwork.
  • Zoned comfort control: Ductless systems allow room-by-room temperature control, reducing unnecessary cooling.
  • Direct air delivery: Conditioned air goes straight into the living space, improving efficiency.
  • Inverter-driven compressors: These systems adjust speed based on demand, using less energy over time.
  • Lower overall consumption: Homeowners often see 30–40% reductions in energy use compared to central AC systems.

Introduction to Ductless Air Conditioning

Ductless air conditioning systems, often referred to as mini split systems, provide an efficient and versatile solution for both heating and cooling individual rooms or entire homes. These systems are made up of an outdoor unit and one or more indoor units, which are connected by refrigerant lines that run through a small opening in the wall. Unlike traditional systems that rely on bulky ductwork, ductless systems are compact and require minimal space, making them ideal for homes where installing ducts is impractical or impossible. By delivering conditioned air directly to specific rooms, ductless air conditioning systems help reduce overall energy consumption and allow homeowners to enjoy customized comfort in every space. Whether you need to cool a single room, a new addition, or your whole home, ductless systems offer a flexible, energy-efficient alternative to conventional heating and cooling methods.

Lack of Air Ducts

Typical central air conditioning systems use a series of independent air ducts to distribute the cooled air to each room. Even the most efficiently designed, well-insulated ducts will allow the conditioned air to warm slightly before it reaches its destination. As ductwork ages, it loses even more efficiency, with joints that leak conditioned air and insulation that becomes less effective or deteriorates over time. In the average air conditioning system, 30 to 40 percent of the energy used for cooling is wasted as air travels through the ductwork and either warms up or leaks out. This is one of the major drawbacks when comparing choosing central or room air conditioning, as ductless systems eliminate this source of inefficiency.

Ductless air conditioning systems feature an interior air handler consisting of an evaporator coil, fan and air filter, which is mounted directly in the room that requires cooling. Mounted outside, the other half features a condenser and compressor in one enclosure, and the two halves are connected through a small opening in the wall that carries the refrigerant lines, electrical cables and other components—avoiding many signs of a failing hvac system. By eliminating the ductwork, ductless air conditioners use 30 to 40 percent less energy than a traditional air conditioning system. A mini split system or ductless heat pump can be installed to provide both heating and cooling, further improving energy efficiency.

Optional Zoning

With ductless air conditioning systems, one or more air handlers can be added to a single compressor unit, with one air handler in each room that requires a cooling system. A mini split system can be installed in individual rooms for customized comfort. The temperature can be adjusted independently at each air handler, allowing some rooms to be cooler than others, or enabling you to completely shut off the cooling system in an unoccupied room. Compared to cooling systems with a single zone, this can save a significant amount of energy and extend the typical air conditioner service life by reducing unnecessary strain on the unit.

To learn more about how ductless air conditioning systems save energy, talk to our cooling experts at . We serve Southwest Florida, including Ft. Myers, Naples, Cape Coral, Sarasota & Bradenton. Installing a ductless heat pump in Sarasota, FL requires a professional HVAC technician due to Florida’s energy codes and licensing requirements for managing refrigerants. Consult a professional to determine the best mini split system or heat pump for your needs.

Components of a Ductless System

A ductless system is composed of several key components that work together to provide efficient heating and cooling. The outdoor condenser unit houses the compressor, condenser coil, and fan, which are responsible for releasing or absorbing heat depending on the mode of operation. The outdoor condenser unit is usually placed on a small pad or mounted on an exterior wall. Inside the home, the indoor unit is mounted on the wall using a secure mounting bracket, and it is important to attach the mounting bracket securely to the wall to ensure stability. When installing components, be sure to insert spacers or connectors as needed to ensure proper alignment and fit during assembly. The indoor unit contains the evaporator coil and fan to distribute conditioned air throughout the room. These indoor and outdoor units are connected by refrigerant lines, which carry refrigerant between the two, as well as electrical wiring for power and control. When attaching the refrigerant lines, carefully attach them to the condenser and tighten the connections to ensure a secure, leak-free connection. It is also recommended to install a lineset cover to protect the refrigerant lines and maintain system integrity. A remote control allows you to easily adjust temperature, fan speed, and other settings from anywhere in the room. Additional components, such as a condensate drain, help remove moisture from the indoor unit, while insulation around the refrigerant lines ensures safety and prevents energy loss. Proper connection and installation of these components are essential to prevent leaks and ensure the system operates efficiently and safely.

How Ductless Systems Work

Ductless systems operate by transferring heat between the indoor and outdoor units through refrigerant lines, providing both cooling and heating as needed. In cooling mode, the outdoor unit compresses the refrigerant, which is then sent through the lines to the indoor unit. Here, the refrigerant expands and absorbs heat from the indoor air, cooling the room as the fan circulates the air. When heating is required, the process reverses: the outdoor unit extracts heat from the outside air—even in cooler temperatures—and transfers it indoors, where the indoor unit releases the heat to warm the room. Ductless heat pumps are ideal for older homes and room additions due to their flexibility and efficiency in providing heating and cooling without extensive renovations. This efficient process relies on proper electrical connections and airflow to ensure the system operates at peak performance. By directly conditioning the air in each room, ductless systems minimize energy loss and provide precise temperature control, making them a smart choice for efficient home comfort.

Energy-Saving Features of Ductless Systems

Ductless systems are designed with several energy-saving features that set them apart from traditional HVAC options. One of the most significant advantages is zone control, which allows you to heat or cool individual rooms or areas independently, rather than the entire home. This targeted approach can lead to substantial reductions in energy consumption, as you only use energy where and when it’s needed. Many modern ductless heat pumps offer smart thermostat integration and remote control options for convenience and customization. Many ductless systems boast high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings, reflecting their superior efficiency. Their compact design further reduces energy loss, as there are no ducts for heat to escape. Advanced features like inverter technology and smart sensors help the system adjust its output automatically, maintaining optimal comfort while minimizing energy waste. With these innovations, ductless systems offer an efficient, cost-effective way to keep your home comfortable year-round.

Outdoor Unit Considerations

When installing a mini split system, careful attention must be given to the placement and installation of the outdoor unit, also known as the outdoor condenser unit. For optimal performance, the outdoor unit should be installed on a stable, level surface—either mounted securely to an exterior wall with a sturdy mounting bracket or placed on a concrete pad. It’s important to choose a location that is shielded from direct sunlight and protected from harsh weather conditions, as excessive heat and exposure can impact the system’s efficiency and longevity. Proper airflow around the outdoor unit is essential; ensure there is ample space on all sides to allow for efficient heat exchange and to prevent overheating. The unit should also be positioned in a spot that allows easy access for routine maintenance and repairs. By considering these factors during installation, you help ensure your mini split system operates efficiently and reliably for years to come.

System Configuration

The configuration of a mini split system is tailored to the unique needs of your space, ensuring maximum energy efficiency and comfort. Typically, a mini split system consists of one outdoor unit connected to one or more indoor units via refrigerant lines and electrical wiring. The number and placement of indoor units depend on the square footage, insulation quality, and specific temperature requirements of each area. Professional installation is crucial to determine the correct system size and configuration, as an improperly sized system can lead to reduced efficiency and uneven comfort. Additional components, such as a condensate drain for moisture removal and a remote control for convenient operation, may be included to enhance the system’s functionality. By carefully configuring the system and ensuring all components are properly connected and insulated, you can achieve optimal performance and energy savings throughout your home or business.

Mini Split System Applications

Mini split systems are renowned for their versatility and energy efficiency, making them suitable for a wide range of applications. Whether you’re looking to improve comfort in individual rooms, add climate control to room additions, or upgrade the heating and cooling in older homes where installing ductwork is not practical, mini splits offer a flexible solution. These systems are also ideal for renovations and historic properties, as they require minimal structural changes. In commercial and industrial settings, mini split systems can be used to provide targeted heating and cooling to specific zones, reducing overall energy consumption. By installing mini splits in individual rooms or areas, you gain precise temperature control and the ability to adjust comfort levels based on occupancy, further enhancing efficiency and reducing energy costs.

Frequently Asked Questions

Question: What are ductless air conditioning systems and how do they differ from traditional ducted systems?
Answer: Ductless air conditioning systems, also known as mini-splits, consist of an outdoor compressor/condenser unit connected to one or more indoor air handlers via refrigerant lines and electrical connections. They do not use ductwork to distribute air; instead, each room (or “zone”) has its own air handler.

Question: How much energy savings can be achieved by using ductless AC systems?
Answer: Because ductless systems eliminate ducts—which can leak air and lose cool air to unconditioned spaces—studies estimate energy savings of around 30 to 40 percent compared to traditional central air systems.

Question: What is “zoning” in ductless AC systems, and what benefits does it offer?
Answer: “Zoning” means different indoor units (air handlers) can be installed in separate rooms, each with its own thermostat or control. This allows you to only cool spaces that are being used and set different temperatures in different areas, reducing wasted energy and improving comfort.

Question: Why do ducts waste so much energy in traditional AC systems?
Answer:
Ducts can leak conditioned air through joints and cracks, and ducts running through unconditioned spaces like attics can allow the air inside them to warm before it reaches the room. Over time, insulation degrades, making leaks worse. These losses can add up to 30 to 40 percent of cooling energy.

Question: Are there any trade‑offs or downsides to a ductless system?
Answer:
Yes. Upfront cost tends to be higher than basic window units, and aesthetics may be a concern since wall-mounted indoor units are visible. Also, while energy savings are real, proper installation, sizing, and maintenance are essential for maximum benefits.
