Air Conditioner

What is SEER? SEER stands for Seasonal Energy Efficiency Rating as defined by the Air Conditioning, Heating, and Refrigeration Institute. Think of SEER as miles per gallon when discussing vehicles. The higher the SEER rating, the more efficient the system is. Currently the minimum rating for Kentucky air conditioning systems installations is 14 SEER equipment. Our product offerings include up to 20 SEER at this time.

What is an Air Conditioner System? An A/C system consists of 3 key components – the outdoor condensing unit (compressor), copper refrigerant line set, and indoor evaporator coil. The system utilizes the furnace blower motor to provide air flow.

Heat Pump

What is SEER? SEER stands for Seasonal Energy Efficiency Rating as defined by the Air Conditioning, Heating, and Refrigeration Institute. Seasonal Energy Efficiency Ratio (SEER) is used for evaluating a heat pump’s efficiency in the cooling cycle. It is the same rating system used for Air Conditioners, making it easy to compare different units. Think of SEER as miles per gallon when discussing vehicles. The higher the SEER rating, the more efficient the system is. Currently the minimum rating for Kentucky heat pump installations is 14 SEER equipment. Our product offerings include up to 20 SEER at this time.
What is a Heat Pump System? A Heat Pump system typically consists of 3 components – the indoor unit called an air handler, copper refrigerant line set, and the outdoor condensing unit (compressor). A heat pump condenser utilizes an internal component (the reversing valve) which switches the outdoor unit between heat and cool modes. The indoor air handler utilizes electric heat strips (auxiliary heat) to supplement the outdoor unit when the outdoor ambient temperatures are below 30 degrees. Heat pumps operate all year long where air conditioner units only operate seasonally.

Gas Furnaces

What is AFUE? AFUE stands for Annual Fuel Utilization Efficiency. Current model furnaces (natural gas or liquid petroleum fueled) are required to have a minimum AFUE rating of 80 percent. Our offerings range from standard 80% efficiency models, up to high efficiency modes (96% or higher) that achieve near-total efficiency.
How do 80% efficient furnaces work? A standard 80% efficient furnace uses at least 80% of the fuel it consumes to generate heat, while the remaining 20% of heat energy is exhausted via the furnace’s venting system. In layman’s terms – for every dollar spent to heat your home, you are getting .80 cents worth of heat, with a .20 cent loss. Standard 80% furnaces utilize a conventional metal vent pipe system, typically vented vertically thru the exterior of your home.
How do 96% efficient furnaces work? A high efficiency furnace (AFUE rating above 90 percent) is considered a “condensating” furnace. It utilizes a secondary heat exchanger to extract heat from the exhaust gases that would otherwise be lost thru the furnace exterior venting system with less efficient models. In layman’s terms – for every dollar spent to heat your home, you are getting .96 cents worth of heat. The venting system differs from conventional 80% furnaces, requiring PVC venting pipes connected to your furnace, vented vertically, or horizontally to the exterior.

Dual Fuel

What is dual-fuel? A Duel Fuel system utilizes a heat pump outdoor condensing unit, in conjunction with a natural gas or liquid petroleum furnace, and an indoor evaporator coil.
How does dual-fuel work? Basically the dual fuel heating system operates as a heat pump until outdoor weather conditions (normally below 30 degrees F) are such that the heat pump needs help to maintain the indoor temperature setting. The Dual Fuel system provides gas heat during this time rather than electric strip heat. The heat pump shuts down when the gas heat is operational. Specialty controls are added to maximize efficiency and fuel consumption between the outdoor heat pump and indoor furnace.
Advantages
Gas heat is more efficient than electric radiant auxiliary heat and less costly to operate.
Heat pumps operate in conjunction with auxiliary heat where dual fuel systems operate the heat pump and gas heat independently of one another.
Dual fuel systems offer the option of only operating in the gas heat mode if the user so desires, such as during extended periods of below freezing weather conditions.
The option of operating the system as a heat pump or gas heat is optional with consideration to utility rate fluctuations.

Ductless

What is a ductless system? Similar to a traditional residential split system, a ductless system consists of 2 components – the outdoor condensing unit, and an indoor air handler. As the name suggests, the key difference is – NO DUCTWORK! The latest inverter technology provides the ability to maintain optimal conditions inside your home without the high energy consumption.
Why ductless? In areas of the home where window A/C units or baseboard heat would typically be considered, ductless systems are more economical and comfortable options. Many of the ductless offerings are in excess of 20 SEER, far above and beyond traditional split systems. These are ideal in new spaces such as room additions, or as supplemental heating/cooling for existing spaces in your home.
Single Zone or Multi-Zone? Single Zone systems condition one or two rooms, while Multi Zone offerings provide independent comfort for up to eight separate rooms on one outdoor condensing unit.

Why Daikin Ductless? Daikin is the World’s No. 1 air conditioning company, with more than 90 years as the leading innovator and worldwide provider of advanced, high-quality comfort solutions for residential and commercial applications.

Package Units

What is a package unit? A package unit is an all-in-one HVAC system that contains all of the components within one outdoor unit. Package units can be utilized in residential applications, but are most often associated with commercial settings. Package unit come in a wide variety of offerings – including air conditioners, gas/electric systems, heat pumps, and even dual-fuel.
