Four Key Concerns When Replacing the A/C

Are you considering replacing the A/C? This is a big decision that requires some research. Before you head to the home improvement store and buy the first air conditioner you see, get a grasp on the following four concerns when replacing the A/C.

Knowing the Right Time

The simplest ways to tell when it’s time to replace the air conditioner are to assess the system’s age and performance:

• Is the equipment 15 to 20 years old?
• Is efficiency dropping?
• Does your home feel uncomfortable when the temperature climbs outside?

If you answer yes to all of these questions, it’s time for a system replacement.

Whether to Replace One or Both Components

If you choose a split-system A/C, it’s best to replace the indoor evaporator coil and outdoor condensing unit at the same time. This ensures both components work together properly, saving you money in the long run by delivering peak efficiency and avoiding breakdowns common when two incompatible components are paired together.

Sizing

An undersized system can’t keep up when the temperature rises outside. On the other hand, an oversized system results in highly fluctuating indoor temperatures and poor humidity control.

To ensure you invest in a properly sized air conditioner, seek the expert sizing capabilities of a knowledgeable HVAC contractor. You know proper sizing is taking place when technicians refer to the calculations found in Manual J. These calculations go well beyond square footage and climate to include other important factors such as home orientation, window layout, number of stories, insulation, air infiltration rates, occupancy level and more.

What Type of System is Best

You have many options for air conditioning your home, including:

• Split-system A/C to provide central cooling for your home.
• Packaged A/C, mostly used in mobile homes and commercial properties.
• Heat pump for year-round central heating and cooling.
• Ductless mini-split to heat and cool one section of your home, such as an add-on with no ductwork.
