AC Replacement: Key Factors You Must Consider

Air conditioning is necessary, especially during the hot and humid summer months. It helps maintain a comfortable indoor temperature by removing heat and humidity from the air. However, after years of use, your AC unit may show signs of wear and tear, making it necessary to consider a replacement.

AC replacement can be daunting, but it doesn’t have to be. This article will explain the key factors for replacing your AC unit to ensure a comfortable and energy-efficient home.

Type of AC Unit

The first factor to consider when replacing your AC unit is the type of unit you want to install. There are various types of AC units, such as:

  • Central air conditioning: This AC is ideal for homes with existing ductwork because of its efficiency in cooling large spaces. It also allows for using programmable thermostats, which can help save energy and reduce costs.
  • Ductless mini-split systems: This type is optimal for homes without existing ductwork. Aside from that, they’re energy-efficient and provide zoned cooling, allowing you to cool specific areas of your home.
  • Portable and window units: These units are ideal for cooling small spaces since they’re easy to install and relatively inexpensive, making them an excellent option for those on a tight budget.

SEER Rating

The SEER rating measures an AC unit’s energy efficiency. The higher the SEER rating, the more energy-efficient the unit is. Remember, you must be vigilant with the SEER rating of your AC replacement since it will affect your energy bills in the long run.

It’s recommended to pick a unit with a SEER rating of at least 13 for optimal energy efficiency. However, higher SEER ratings may come with a higher price tag, so it’s important to balance cost and efficiency when choosing.

Size of AC Unit

The size of your AC unit is another crucial factor to consider when replacing your unit. An AC unit that’s too small won’t be able to cool your home efficiently, while an AC unit that’s too large can lead to wasted energy and increased costs.

To determine the right size of AC unit for your home, check the square footage of your home, the number of windows, the level of insulation, and the height of your ceilings. You can also consult an HVAC professional to determine your home’s right AC unit size.

Installation Cost

The installation cost can vary depending on the unit type, the size of your home, and the complexity of the installation. That’s why it’s best to get quotes from multiple HVAC professionals to compare costs and choose the best option for your budget. However, remember that the cheapest option may not always be the best.


You might not think about it, but AC replacement is about getting the best price and the best warranty. A good warranty will cover the cost of any repairs or replacements that are needed during the warranty period. Look for a warranty covering parts and labor for at least a few years. This will give you peace of mind learning that your investment is protected.

Final Thoughts

Replacing an AC unit is a significant investment that requires careful consideration of several key factors. By evaluating these factors and working with a reputable HVAC professional, homeowners can make an informed decision and choose an AC unit that will provide long-lasting comfort and energy savings.
