Will a new AC unit cool my house better?

Sep 7

Central air conditioning can keep your home cool in summer and comfortable in winter. You may not like the increased energy consumption, the ozone-depleting refrigerant and the noise from the outdoor condensing unit.

Air conditioning technology has made it possible to have a comfortable, fantastic home with no drawbacks. Upgrade to an energy-efficient, new air conditioner and reap the benefits.

Upgrade your central AC for the best benefits

An upgrade will first reduce your energy consumption. An average-sized house with an air conditioner system 20 years old might require 6 kWh to cool. Modern AC systems can cool the same house with as little as 1.71kWh of electricity. Advanced features such as the two-stage scroll compressor are responsible for this remarkable performance. It replaces the single-stage piston-driven compressors that were used in the past.

A second benefit to upgrading your air conditioner system is the possibility of reducing your environmental impact. R410A, a modern refrigerant, is the replacement for R22. This contributes to ozone loss. If your current air conditioner is running on R22 and develops a refrigerant leaking problem, now is the time to switch to R410A-compatible units. R22 is being phased out and will become illegal in the USA in 2020.

A new air conditioner system is quieter, which is the third benefit. Modern air conditioners are quieter thanks to improved compressor technology and fan blade shape. This is approximately one-fifth the noise that older units produce. You can now relax in your yard without worrying about the AC compressor's noise.

Efficiency SEER ratings

The Seasonal Energy Efficiency Ratio is also known as SEER. This number shows how much electricity is needed to heat an indoor area. The higher this number is, the more efficient your air conditioner system is.

The minimum rating for new air conditioners is currently 13 SEER in the northern states and 14 SEER south. Some systems can have SEER ratings up to 25. It is legal to continue operating existing units that have lower efficiency ratings.

Many AC units with SEER ratings below 10 are still in service. These systems may not run at their best after a decade of wear and tear. A 10 SEER unit will likely operate more efficiently than an 8 SEER unit.

Below is a chart that shows how much electricity you could save by switching to an air conditioner with a higher SEER rating.

Proper sizing is essential for your system.

It doesn't matter if your AC system is rated at 13 SEER or 25 SEER; it is essential to size it to maximize efficiency properly. The system will run for shorter periods, leading to poor dehumidification. This can make the house feel fantastic but clammy. Under-sizing can cause excessive wear, overheating, and discomfort on hot summer days.

Heat and cooling are measured in British Thermal Units (BTUs) per hour. The tonnage of refrigeration is used to size air conditioning systems. One ton of air conditioning is equal to 12,000 BTU/hour. It is a good rule of thumb to have a one-ton system for cooling a home that is 1,000 square feet.

But proper air conditioner sizing is more than measuring square footage. The ideal AC size depends on ceiling height, home layout, air leakage and sun exposure. Petro Home Services can help you choose the correct size unit for your home.
