Air Conditioning Basics: A Quick Reference Guide

Tuesday, May 9th, 2017

Air conditioning systems are crucial to comfort in Southwest Florida, and whether you are installing a new system or having one repaired, it is a good idea to know a few air conditioning basics to simplify the process.

How an Air Conditioner Works

Refrigerant enters the evaporator coil indoors as a cool, low-pressure liquid, where it absorbs heat as a fan circulates indoor air over the coil. This boils the refrigerant, turning it into a gas. Exiting the evaporator, the refrigerant enters the compressor, which increases the pressure of the refrigerant, heating it further, and pumps it through the system.

The refrigerant then enters the condenser coil, where it loses heat and cools to a liquid, using a fan that blows outside air over the coils. Finally, the high-pressure, cool liquid flows through an expansion valve, reducing its pressure, and back into the evaporator to repeat the cycle.

Efficiency Rating

One of the most important air conditioning basics to learn about is the SEER or seasonal energy efficiency ratio. This number indicates how much energy is used by the system over a cooling season, with higher numbers indicating more efficient performance and lower cooling costs. Typical models have a SEER of 13 to 16, while the best have a SEER of 20 or above.

Size

The cooling capacity of a central air conditioner is typically rated in tons, or the ability of the system to remove 12,000 British thermal units, or BTUs, of heat per hour. A 5-ton system, for example, would remove 60,000 BTUs of heat. Smaller air conditioners, like window units, may be rated in BTUs alone.

Types

Central air systems feature a condenser unit, a single evaporator and a system of ducts to deliver air. Ductless systems have an evaporator and air handler in each room, connected to a single condenser, eliminating the ducts and simplifying installation. Heat pumps are similar to central air systems, but can be reversed to provide heat, as well.

How To Determine The Best A/C Equipment For Your Home

Tuesday, April 4th, 2017

If you are considering a new air conditioner for your Southwest Florida home, determining the best A/C equipment for your needs can be difficult. There are several types of systems, differences in cooling efficiency and a variety of features. Here are a few tips for determining the best A/C equipment for your home:

System Type

A conventional central air conditioner offers cooling only, with an outdoor condenser unit and an indoor air handler that delivers conditioned air though a system of ducts. A heat pump looks and operates similar to a central air conditioner, but it is reversible, allowing it to also provide heating. Ductless mini split systems feature an individual air handler for each room or zone, connected to an exterior condenser, and they are available with cooling only, or both cooling and heating. If you have ducts installed, either a central air conditioner or a heat pump would be a good choice. For homes without ducts or for a single room, a ductless system can be more cost-effective. If you require both heating and cooling, a heat pump or a ductless system would be the best choice.

Energy Efficiency

Air conditioners are classified by their SEER rating, or seasonal energy efficiency ratio. A higher number means greater energy efficiency, with systems typically ranging from 14 SEER to over 20. By paying a bit more initially for an efficient system, you can earn that money back over its lifetime through reduced cooling costs. For systems that offer heating, look for an HSPF, or heating seasonal performance factor, of higher than 8 for the best energy efficiency.

Features

Optional features like multiple-speed compressors and blower motors provide more consistent cooling and quieter operation. Zoning systems enable the temperature in each zone to be controlled independently, allowing you to reduce cooling in unused rooms and save money. Wi-Fi thermostats allow for easy programming and increased energy savings. Select a system with the features that are best for your needs and your budget.

Ductless Heating And Cooling: A Handy Reference

Tuesday, March 28th, 2017

In a conventional HVAC system, as much as 30 percent of the energy used for heating and cooling is wasted, due to leaking or inadequately-insulated ductwork. A better alternative, especially for homes without an existing HVAC system, may be a ductless heating and cooling system. By placing the air handler directly in the room to be heated or cooled, and eliminating the air ducts, a ductless heating and cooling system can be far more efficient and easier to install, as explained in this guide on how ductless systems save energy. Careful planning is essential for ductless mini split installation, including proper placement, system performance, and compliance with local building codes.

How a Ductless Heat Pump Installation Works & What to Expect

  • System components: An outdoor condenser/compressor + one or several indoor air handlers (wall, ceiling, or floor‑mounted) connected via small conduit through a wall or ceiling.
  • Minimal structural change: Needs only a 3‑4‑inch opening per handler; fewer ducts means easier install in homes or additions without existing HVAC. 
  • Efficiency ratings matter: Typical SEER ratings are 16–20+; average HSPF is 7–8, with high‑efficiency units above that. 
  • Zone control vs whole‑home: Can be single‑zone (one room) or multi‑zone (multiple air handlers with independent control) depending on home size and comfort needs.

Introduction to Mini Split Systems

A mini split system is a modern solution for heating and cooling that features both indoor and outdoor units working together to keep your home comfortable year-round. The outdoor condenser unit, which houses the compressor, fan, and condenser coil, is connected to the indoor unit by refrigerant lines. The indoor unit contains the evaporator coil and fan, delivering conditioned air directly into your living space. Mini split systems are especially popular in homes without existing ductwork or in spaces where adding traditional HVAC systems would be difficult or costly. Known for their energy efficiency and quiet operation, these systems offer flexible installation options and can be tailored to fit the unique needs of any room or zone in your home.

Installation Process

Ductless or mini split systems consist of an outdoor condenser and compressor unit, one or more interior air handlers that contain an air filter, evaporator and fan, plus a conduit that connects the two halves. The air handlers are available in a variety of styles, including floor-level, wall and ceiling-mounted models, and a conduit containing the refrigerant and electrical lines connects each air handler to the condenser through a small 3 to 4-inch opening in a wall or ceiling, which makes them one of the best ac equipment options for homes. The heat pump installation involves unpacking both an outdoor condenser unit and an indoor unit. During ductless mini split installation, a small hole or pilot hole is drilled in the interior wall to run the line set and refrigerant line, and the hole should be properly sealed with a cover to prevent air or water infiltration. The outdoor condenser unit can be installed on concrete blocks to elevate it above ground level, especially in areas prone to moisture. Specialized tools are often required for mini split installation, and electrical upgrades may be necessary to ensure your house can support the new system.

Mounting brackets and a mounting plate are used to securely mount the indoor unit to the wall, ensuring stability and proper alignment. Ductless systems require minimal remodeling to install, and are perfect for homes or additions that lack a complete cooling and heating system. It is important to adhere to local building codes and obtain the necessary permits to avoid fines, and professional installation is recommended for safety and compliance. The cost and labor costs of ductless mini split installation can vary depending on system complexity, number of zones, and any required electrical upgrades.

SEER and HSPF Ratings

SEER stands for seasonal energy efficiency ratio, and represents the amount of electricity used for a cooling season. A mini split heat pump cools and heats with great efficiency, and ductless systems typically have a SEER from 16 to 20 or more, with higher ratings indicating greater efficiency. While higher SEER ratings generally increase upfront costs, they can lower energy bills, offering potential long-term savings. The HSPF, or heating seasonal performance factor, measures the electricity used for a heating season, with average systems receiving ratings of 7 to 8, and high-efficiency models receiving an 8 or above, which is helpful to know when upgrading your ac unit. By investing in a more efficient system, you will reduce your long-term utility costs. Understanding the efficiency of your ductless mini split system can help homeowners make informed decisions.

Single or Multiple-Zone Systems

Some ductless heating and cooling systems serve one room or area only, while larger systems have an upgraded condenser and typically up to 5 air handlers to provide whole-home heating and cooling with independent temperature controls for each zone. Mini splits and splits offer flexible installation options for different areas of the house, making a ductless mini split system suitable for various house types, including older homes and additions. A mini split heat pump, or heat pump, provides both heating and cooling functions with great efficiency, making it a versatile solution for year-round comfort. After installation, it is important to perform a test and thorough testing of the system to ensure it heats and cools as expected.

How Ductless Systems Work

Ductless systems, often referred to as mini split systems, operate by moving heat between the indoor and outdoor units through refrigerant lines. During colder months, the outdoor unit extracts heat from the outside air and transfers it indoors via the refrigerant, where the indoor unit releases the warmth into your space. In the summer, the process reverses: the indoor unit absorbs heat from your home and sends it outside, effectively cooling the room. This efficient process eliminates the need for extensive ductwork, making ductless systems a practical choice for both heating and cooling individual rooms or entire homes. The direct connection between the indoor and outdoor units ensures reliable performance and consistent comfort.

Benefits of Ductless Systems

Choosing a mini split system brings a range of benefits, starting with increased energy efficiency that can lead to noticeable savings on your energy bills. Ductless systems are designed to be installed in a variety of locations—on walls, floors, or ceilings—making them adaptable to almost any space. Their quiet operation and minimal maintenance requirements add to their appeal, while advanced filtration helps improve indoor air quality. Ductless systems are significantly quieter than traditional HVAC systems, making them suitable for bedrooms and living areas. One of the standout features is zone control, allowing you to set different temperatures in different rooms for personalized comfort and reduced energy waste. With a mini split system, you gain precise control over your indoor environment, enjoy improved air quality, and benefit from the overall efficiency of ductless systems.

Pre-Installation Considerations

Before you install a mini split system, it’s important to plan carefully to ensure optimal performance. Start by determining the correct system size based on the square footage of the area you want to heat or cool, as well as factors like insulation and local climate. Properly sizing a ductless heat pump is essential for comfort and efficiency; an oversized unit will cycle too quickly, while an undersized unit will run constantly. Selecting the right location for both the indoor and outdoor units is crucial—avoid placing the outdoor unit in direct sunlight and make sure there’s enough space for proper airflow. Electrical connections are another key consideration; you may need to install a disconnect box and run new electrical wiring to power the system. Consulting with a licensed HVAC contractor can help you navigate these decisions, ensuring your mini split system is installed safely and efficiently for maximum comfort.

System Configuration

A mini split system offers flexible configuration options to suit your specific needs. You can connect multiple indoor units to a single outdoor unit, allowing you to control the temperature in different rooms or zones independently. Indoor units can be mounted on walls, ceilings, or even floors, while the outdoor unit can be installed on a concrete pad or mounted on an exterior wall for convenience. Proper condensate drainage is crucial to prevent water damage and mold growth. With a remote control, you can easily adjust temperature, fan speed, and other settings to maintain your ideal comfort level. Proper installation and regular maintenance—such as cleaning filters and checking for leaks—are essential to keep your system operating efficiently. With the right setup, a mini split system delivers reliable, energy-efficient heating and cooling for multiple rooms, tailored to your preferences.

What to Expect when Upgrading your AC Unit

Tuesday, 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.
