Don't Replace Your AC Unit Without Knowing These Crucial Precautions

Summer is here, and with it comes the unbearable heat that often leads homeowners to ponder replacing their AC unit. While it may be tempting to throw in the towel on an older unit, there are crucial precautions to consider before shelling out a large portion of your savings on a new system. Here are three things to keep in mind before making a hasty decision:

First, assess the age of your current unit. If it's only a few years old or has been well-maintained, a repair may be all that's needed. It's crucial to have a trusted HVAC technician evaluate the condition of your current AC, as they can pinpoint any underlying issues that require attention, such as clogged ducts, a dirty filter or a broken fan blades.

Secondly, evaluate your home's insulation and energy efficiency. Upgrading your windows, adding insulation and sealing drafts can make a considerable difference in your home's indoor temperature control. Similarly, installing a programmable thermostat can help manage energy use when you're away from home, saving you money in the long run.

1. Consider the size of your unit

Before buying a new AC unit, it's important to consider its size. AC units are sized according to how much heat they can remove from your home in an hour. If you choose a unit that's too small, it won't be able to cool your home effectively. On the other hand, if you choose a unit that's too large, it will cycle on and off too frequently and won't be able to remove humidity efficiently.

One way to determine the appropriate size of the AC unit for your home is to have a professional calculate your home's cooling requirements using the Manual J load calculation. This calculation takes into account factors like the size of your home, its orientation to the sun, and the insulation in your walls and attic. Once you have the results of this calculation, you can choose an AC unit that will provide the appropriate cooling for your home.

It's also important to note that bigger isn't always better when it comes to AC units. A unit that's too large will use more energy and won't be as effective at removing humidity from your home. Choosing the right size of the AC unit is crucial to ensure that your home stays cool and comfortable while also maximizing energy efficiency.

2. Research Energy-Efficient Options

If you're already considering replacing your AC unit, it's worth taking the time to research energy-efficient options. Not only will this help you save money on energy bills in the long run, but it can also reduce your carbon footprint.

Look for AC units with high SEER ratings (Seasonal Energy Efficiency Ratio). The higher the SEER rating, the more energy-efficient the unit is. Consider investing in a unit with a SEER rating of at least 14 or higher.

You can also research Energy Star-certified AC units. These meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. Energy Star-certified units can save up to 20% on energy bills compared to non-certified units.

Additionally, consider getting a programmable thermostat, which can help you save even more energy. This type of thermostat adjusts the temperature based on your schedule, so you're not wasting energy cooling your home when no one is there.

Remember, investing in an energy-efficient AC unit may come with a higher upfront cost, but the long-term savings can make it well worth it. Plus, you'll be doing your part to help the environment.
