Conventional Air Conditioning
The Conventional AC System means adding an evaporator coil to your existing furnace, or installing an air handler (fan coil) in a basement, attic, or living space and connecting to an outdoor compressor/condensing unit. Using the existing ductwork, or a newly designed supply and return system – the conventional system distributes cooled air throughout the home while removing humidity from the living space. But it’s not as simple as a “box that cools your home”. There are choices and options available to you.
It is assumed that when a professional comes into your home, you will be provided an estimate for a properly sized unit that will cool your space. But how is this accomplished? By measuring the square footage of the home, the duct sizing and distribution, the cold air returns, and the blowers capacity to handle the load, we can ensure that your system is properly sized and will explain if and why any modifications to the existing set up will be needed. Not every home has the same requirements for many different reasons – and this will be discussed on your consultation.
EER and SEER. Maybe you’ve heard these acronyms before, but a little explained on this. EER stands for “Energy Efficiency Ratio” and is determined by the cooling output of a unit divided by the power input. SEER stands for “Seasonal Energy Efficiency Ratio” and uses a range of varying outdoor temperatures to arrive at its rating.
It’s important to make sure you are comparing “apples to apples” when getting information on a unit or a set of comparable units. The simplest way to compare these units is by understanding that SEER and EER are like miles per gallon for your air conditioning. The bigger the better! There are many cost calculators and apps out there that will show the savings from a 13 Seer vs. a 16 Seer and allow you to put in your electric costs to show true savings. Remember though, if you are adding AC for the first time, you can safely expect an increase in your electrical usage in the summer, and higher SEER/EER ratings will decrease the increase.
The federal government rebates for high residential HVAC equipment can be found here,
https://www.energystar.gov/about/federal_tax_credits but air conditioning rebates of up to $300 are available on units with:
• SEER>16, EER>13 Split System AC
• SEER>15, EER>12.5 Air Sourced Heat Pump
Federal minimum efficiency on heat pumps are 14 SEER and 13 SEER on conventional AC.
Staging and Variable Speed Compressors
Standard air conditioning systems are typically “single staged” systems that have 1 speed…on. To give you a comparison, this would be like if every time you drove your car, you slammed the pedal to the floor then slammed on the brakes to stop. Your 13, and 14 SEER systems are typically single stage systems. Single stage systems are designed for the worst possible outdoor temperatures, which occur less that 5% of the time.
Higher Efficiency units are available in 2 stage models, which can either be a singular 2 stage compressor, or an actual dual compressor system. These compressors have the ability to stage down to a lower speed when the outside temperature is milder, or if the indoor temperature only needs to be maintained, rather than catching up large differentials in temperature. To use the car example again – now you have 2 speeds at which you can drive. This will make the unit more efficient, and decrease the wear and tear on a single compressor that is operating at 100% capacity, 100% of the time.
Newer to the conventional residential market is variable speed compressors. The variable speed
compressor, such as in the case of the Trane XV20i, cant stage from 30% to 100% in 1/10 of a degree increments. This means 700 stages of cooling – or your true driving, or true comfort experience. Combined with a modulating variable speed indoor unit, is the most efficient home HVAC system with the latest and greatest technology. These systems are designed to level out the performance curve and eliminate temperature differentials in the home based on real time demand at the thermostat or zone sensors. System efficiency can reach 18-21 SEER depending on model.
As temperatures keep increasing outside, the tolerance levels seem to have decreased for homeowners in Western New York. And with the surging growth in the ductless air conditioning market, there are more options available for homeowners with hot water and steam heating systems.
