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.
