How Much Cash Will The XC25 Save You?

It’s true, the XC25 earns homeowners money. Most customers with high utility bills and inefficient air conditioning systems experience 40%+ reductions in monthly electricity bills. With 10+ years likely lifespans (proper maintenance required), and the typical payoff through energy savings alone being only a couple years; the fact is that the XC25 does indeed generate real cash.

When the energy rates are as high as they are here in Cayman, we get quite a few questions about efficiency.

The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute in its 2008 standard AHRI 210/240: Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal unit (BTU) to the energy consumed in watt-hours. The coefficient of performance (COP), a more universal unit-less measure of efficiency, is discussed in the following section.

This is by far one of the most asked questions when a homeowner is considering upgrading to high efficiency. The truth is that an air conditioning system, efficient or not, will always be the most expensive appliance you purchase for your home.

We often find it easy for customers to understand the scenario when we explain the difference between cost and price. While the up-front cost on our highest efficiency products is considerably more expensive than a typical baseline economy system the final price is far less. In fact, the end investment price is actually $0.

We’re not pulling your leg. Our XC25 is built to last upwards of 10 years. When considering the difference in monthly energy costs between a much less efficient system and the XC25, the payoff through savings is typically less than 3 years. This means that most customers will make their efficiency equipment investment back in less than half the lifespan of the equipment. For the rest of the equipment’s life (with proper maintenance) owners continue to enjoy the same savings for many years after the equipment has been paid for in the form of lower utility bills

It’s also important to note that since our Lennox products are world recognized as extremely durable (even in the Cayman elements), many banks and other lenders offer competitive financing options for upgrading your major home appliances which often requires little or no money down.

The Polar Bear Efficiency Calculator is remarkably accurate because it’s based on the mathematics incorporated into an energy savings calculator developed by the manufacturer of our equipment, Lenox. If you’re interested in seeing the original efficiency calculator from Lennox check it out here.

What we’ve done with the Polar Bear Efficiency Calculator is modify the logic from the manufacturer’s calculator to be in line with a real world scenario here in Cayman. The Lennox calculator is geared mainly towards North America where homeowners are using both heating and cooling in any given year plus they are not paying anywhere near the utility rates we pay here in Cayman. What we’ve done is create our own based on local utility rates and hours of cooling needed in most scenarios.

The calculated savings is of course only an estimate but believe it or not we can get almost exact with our savings calculations should you schedule us for an efficiency audit and equipment quotation.
