5 Ways to Reduce Strain on your AC System

February 21st, 2017

With the hot and humid weather in Southwest Florida, any extra stress on your air conditioner can not only increase your energy usage and utility costs, but it can also lead to premature failure of the system. By taking a few simple precautions and keeping up with routine maintenance, extending the life of an HVAC system is possible, and relatively easy.

Have the System Inspected Twice a Year

Routine maintenance is the key to extending the life of an HVAC system. Have a professional inspect the system at least twice a year, performing regular maintenance like cleaning the coils and changing the air filter, as well as looking for anything that may pose a problem in the future. With the system in prime condition, it will not have to work as hard, extending its useful lifespan.

Replace the Air Filter Often

Between service visits, you should check the air filter yourself at least once a month. A clogged filter significantly reduce efficiency and make your system work harder, shortening its lifespan. Also, keep the outdoor condenser unit free of leaves and other debris to keep the system running smoothly.

Seal and Insulate the Air Ducts

As much as 40 percent of the energy typically used for cooling is wasted in poorly sealed and insulated ductwork. By having a professional seal and insulate your air ducts, your system will operate more efficiently, reducing your energy costs.

Install a Programmable Thermostat

When you are away from home, raising the temperature about 5 degrees can not only reduce cooling costs, but it also decreases stress on your air conditioning system. A programmable thermostat makes raising the temperature and returning it to normal easy and automatic.

Minimize Heat Gain

Extra heat in your home adds undue stress to your air conditioner. Close the blinds or shades during the daytime to prevent solar gain, and avoid heat-generating activities like cooking, bathing and washing dishes or clothes until the evening, when it is cooler.

What to Expect when Upgrading your AC Unit

February 7th, 2017

Now that the weather is a bit cooler in Southwest Florida, and the demand on your air conditioning system is lower, it is the perfect time to consider upgrading if your system is showing its age.

What to Expect with a Cooling Replacement

  • Higher energy efficiency: Modern AC units have SEER ratings of 13 or higher (often 20+), greatly reducing power usage compared to older units which may only be SEER 6–10. 
  • Better sizing: Upgrades use Manual J load calculations to size systems properly, taking into account layout, insulation, number of rooms, and occupants.
  • Advanced features: Newer models include variable speed compressors/fans, improved coil design, zoned systems, and smart / WiFi thermostats to enhance comfort and efficiency.

Here are a few of the many benefits you can expect when upgrading your air conditioner:

Improved Energy Efficiency

Today’s air conditioning systems use much less energy than systems made even 10 or 15 years ago, which will significantly reduce the amount of money you spend cooling your home each month. The energy efficiency of an air conditioning system is represented by a rating known as its SEER, or seasonal energy efficiency ratio, with a higher number being the most efficient. Older systems could have a SEER of as low as 6 to 10, while today’s minimum is 13 SEER, and the most efficient systems earn ratings of 20 SEER or above, making them comparable in savings to ductless heating and cooling systems.

Better Sizing Methods

Many older air conditioners were sized for a home using rough estimates based on square footage alone. This often lead to systems that were smaller, or, more often, larger than necessary, which results in inefficient operation and increased maintenance costs. Today’s professional HVAC technicians use a Manual J load calculation to properly size air conditioning and heating systems, which accounts for not only the size of the home, but also the number of rooms, the interior layout, the type of insulation, the number of occupants and many other factors. This ensures a much more efficient setup and pairs well with maximizing energy efficiency using a thermostat.

New Technologies

 Not only will upgrading your air conditioner result in better energy efficiency and lower cooling costs, but you will also be able to enjoy the latest technologies for improved comfort and convenience, such as advanced options found in mini split air conditioner systems. Many of today’s most popular systems feature improved coil designs that cool more efficiently, variable speed compressors or fans that improve comfort, optional zoning systems that allow independent temperature adjustments in different areas, and optional WiFi thermostats that save energy and are easily programmed.

Frequently Asked Questions

Question: What improvements in energy efficiency can I expect when upgrading my AC unit?
Answer: Modern air conditioners have much higher SEER ratings compared to units from 10‑15 years ago. Older systems might have SEERs of 6‑10, while today’s units start at 13 SEER and many high‑end models reach 20 or above. This translates to lower monthly cooling costs.

Question: Why is accurate sizing of a new AC system important?
Answer: If an AC is too small it can’t sufficiently cool the space; if too large, it cycles on/off inefficiently, increasing wear and energy usage. Professionals now use a Manual J load calculation considering room count, insulation, home layout, and other factors to size the unit properly.

Question: What newer technologies are available in modern air conditioners?
Answer: Upgrades often include improved coil designs, variable‑speed compressors or fans, zoning systems for independent control of different areas, and smart or WiFi thermostats. These enhance comfort, reduce wasted energy, and offer more precise control.

Common AC Problems in South Florida and What to do About Them

January 31st, 2017

With weather that is quite often hot and humid, a large part of maintaining your Florida home is making sure that your air conditioner is running correctly and efficiently. There are several problems that, as a homeowner, you may be able to solve yourself to avoid an unnecessary service fee.

Frozen Coil

In many cases, a frozen coil is the result of a simple airflow issue. The air filter could be extremely dirty or clogged, or the return ducts could be blocked. Check the air filter and replace it with a new one if necessary, or clean and reinstall it if it’s reusable. Check all the supply and return vents in your home for blockages and clear the obstructions. If the problem remains, the cause may be more serious, such as a refrigerant leak, and you will need professional assistance.

Poor Cooling Performance

If not enough cool air is being delivered into your home, the problem may be a dirty evaporator coil, which is located in or near the air handler. Carefully clean the coil with a soft brush and a vacuum. Also, make sure there is no debris in or around the outdoor condenser unit. If there is, turn off the power, remove large debris by hand and rinse the coil with a garden hose to remove the rest.

System Won’t Turn On

In most cases, this is a simple electrical fault. Reset the breakers that power the air conditioning system, and make sure that the compressor overheat circuit has not been tripped. If this does not fix the problem, or the breakers and safety circuits trip repeatedly, your air conditioner may need professional repairs.

System Cycles On and Off Excessively

This typically happens when the outdoor condenser unit is dirty or its airflow is blocked by vegetation or debris, though it could also be caused by a dirty evaporator coil. Clean both coils and have the system inspected if the problem remains.

How Ductless Air Conditioning Systems Save Energy

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.

Controlling the System

Operating a mini split system is straightforward and user-friendly, thanks to the included remote control. With the remote, you can easily adjust the temperature, select the desired fan speed, and switch between heating, cooling, or other operating modes to suit your comfort needs. Many modern mini split systems also offer advanced features such as programmable timers, occupancy sensors, and integration with smart home systems, allowing for even greater control and convenience. Proper use of these controls is key to maintaining energy efficiency, as you can tailor the system’s operation to match your schedule and preferences.

Installing a mini split ductless system often requires careful planning to ensure compliance with local building codes. The outdoor unit should be installed in a location that is well-ventilated, protected from direct sunlight, and shielded from harsh weather to maximize its lifespan and efficiency. The indoor unit must be located in a spot that allows for optimal function and ease of connection, and securely mounted to a sturdy wall using a mounting bracket, attaching the unit properly with recommended methods to ensure it is level and positioned for optimal airflow. Refrigerant lines and electrical wiring must be carefully connected and insulated to prevent leaks and energy loss. A small hole is drilled through the exterior wall to accommodate the line set, and it’s important to ensure proper drainage around the opening to prevent water accumulation and potential damage, as well as to seal this opening properly to avoid air leaks. Because installation requires specialized tools and expertise, professional installation is highly recommended. Following the manufacturer’s instructions and adhering to local building codes will help ensure your ductless system delivers reliable, efficient comfort for years to come.

Maintenance and Repair

To keep your mini split system operating efficiently and to maximize its energy efficiency, regular maintenance is essential. This includes cleaning or replacing the air filters in the indoor unit, inspecting the refrigerant lines for signs of wear or leaks, and checking all electrical connections for safety and reliability. The outdoor unit should be kept free of debris and checked periodically to ensure proper airflow and prevent overheating. Scheduling annual professional maintenance is highly recommended; a qualified technician can thoroughly inspect the system, clean the outdoor unit, check for refrigerant leaks, and verify that all components are functioning correctly. If you notice any issues, such as reduced performance or unusual noises, contact a professional for repair.

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.

What You Need to Know about Mini Split Air Conditioners

December 20th, 2016

Conventional air conditioning systems waste up to 40 percent of the energy they use through losses in the air duct system. By eliminating ducts, mini split air conditioners offer a more efficient alternative that’s easy to install in existing homes, new homes or additions. If you’re considering mini split air conditioners for your home, it helps to review air conditioning basics in this guide.

What do you need to know before installing a mini-split (ductless) heat pump?

  • A mini-split system consists of an outdoor condenser unit and one or more indoor air handlers (wall‑ or ceiling‑mounted), connected via refrigerant lines and electrical wiring.
  • No air ducts are needed — systems are installed through a small 4‑6‑inch opening, which makes retrofits easier and reduces energy losses.
  • Mini‑splits are typically 30‑40% more efficient than traditional ducted AC because there’s no ductwork, which cuts down on energy waste.
  • They cost more upfront (up to ~30% higher), but the energy savings can recover the extra cost over time.
  • You can choose between single‑zone or multi‑zone mini‑splits to cool (or heat) different areas independently, which can save money by only conditioning occupied spaces.

Answer: A mini‑split system has two main parts: an outdoor condenser and one or more indoor air handlers, which can be wall‑ or ceiling‑mounted. They are connected via refrigerant lines and electrical cables through a small opening (4‑6 inches), so installation requires very little construction.

Question: How much more efficient are mini‑split systems compared to traditional ducted AC systems?
Answer: Mini‑split systems are typically 30 to 40 percent more efficient than standard, ducted systems because they eliminate the energy losses associated with air ducts.

Question: What is the cost trade‑off when choosing a mini‑split system?
Answer: The upfront cost for mini‑split systems tends to be up to 30 percent higher than traditional AC systems. However, energy savings over time—and the flexibility to add cooling in areas without ducts—can help recover that initial investment.

Question: What is “zoning” in mini‑split systems, and what are its benefits?
Answer: Zoning refers to having multiple indoor air handlers (zones), each with its own temperature control. This allows you to cool only the spaces you use most, reducing energy consumption in less‑used zones and improving overall comfort.

4 Tips to Save Energy This Fall

December 6th, 2016

With the mild weather of fall, now is the perfect time to make a few improvements around your home. If you are suffering from high utility bills, here are four easy ways that you can reduce energy consumption in your Southwest Florida home:

Have Your HVAC System Serviced

Things like clogged air filters, poorly-lubricated blower motors and dirty condenser or evaporator coils can make your HVAC system work harder than necessary to keep you comfortable, increasing your energy consumption and utility bills. To save energy and extend the life of your system, have an HVAC professional inspect it and perform any routine maintenance that may be required. After the visit, check the air filter often and change it as necessary to keep your system running efficiently.

Install a Programmable Thermostat

By adjusting the temperature in your home while you are at work or asleep, you can reduce the energy consumption of your HVAC system by as much as 10 percent. A programmable thermostat is the easy way to do this, as it can automatically adjust the temperature, then return it to normal so that your home is comfortable when you come back from work or wake up. In warm weather raise the temperature 10 to 15 degrees, and in cool weather reduce it.

Seal and Insulate Your Home

Air leaks can significantly increase energy usage in any season by allowing conditioned air to escape and outside air to enter.. Use weatherstripping and caulk to seal around drafty windows or doors, and use caulk or expanding foam insulation to seal penetrations made for pipes, cables, dryer vents and other openings in your exterior walls. Have your insulation levels checked, especially in the floors, walls and attic, and add more if necessary.

Reduce Your Water Heater Temperature

Many water heaters are set to 140 degrees or higher from the factory, which not only wastes energy but also may cause scalding. A setting of 120 degrees can reduce your costs, while still providing plenty of hot water.
