5 Mistakes to Avoid During Your AC Replacement Process

Replacing your air conditioning system is an important decision that requires careful consideration. Whether your current unit has stopped working or is simply no longer efficient, this process can be overwhelming. Many factors must be considered, from choosing the right model to deciding on installation details. 

To ensure you make the best choice and avoid costly mistakes, we’ve highlighted five common errors homeowners should avoid during AC replacement.

Common Mistakes to Avoid During Your AC Replacement Process

Here are the top five mistakes to avoid during your AC replacement process.

Not Choosing the Right Size AC Unit

One of the most common mistakes people make when replacing their AC unit is choosing a system that’s either too large or too small for their home. A system that’s too small will struggle to cool your home efficiently, leading to higher energy bills and more excellent wear on the system. On the other hand, a unit that’s too large will cycle on and off more frequently, wasting energy and causing unnecessary strain on the compressor.

How to avoid this mistake:

• Hire a professional HVAC technician to perform a load calculation. This process considers your home’s size, insulation, and other factors to determine the proper system size.

• The system must match the cooling needs of your home to ensure efficiency and comfort.

Getting the right size AC unit ensures your system runs efficiently and doesn’t waste energy or money.

Overlooking Energy Efficiency

When shopping for a new air conditioning system, it can be tempting to focus only on the unit's initial price. However, energy efficiency is just as important. While an energy-efficient system may have a higher upfront cost, it can save you money in the long run by reducing your energy bills.

How to avoid this mistake:

• Look for units with a high SEER (Seasonal Energy Efficiency Ratio) rating. The higher the SEER, the more efficient the unit is.

• Consider models that are ENERGY STAR® certified, as they meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).

Focusing on energy efficiency can reduce your home’s overall environmental impact and save you money on your monthly bills.

Choose a Low-Quality Installer

No matter how efficient or advanced your new air conditioning system is, it won’t perform well if installed incorrectly. Improper installation can lead to various problems, such as refrigerant leaks, poor airflow, and even early system failure. Choosing an inexperienced or unqualified installer can incur extra costs for repairs or a complete system replacement much sooner than expected.

How to avoid this mistake:

• Always hire a licensed HVAC contractor with experience in AC installation. Look for contractors who have good reviews and ask for references.

• Ensure the installer is familiar with the specific brand and model of the AC unit you purchase. Installation techniques can vary depending on the system.

A proper installation ensures that your AC unit runs smoothly and efficiently, saving you money in the long term and reducing the chances of unexpected repairs.

Skip Regular Maintenance

After installing your new AC unit, it’s easy to assume everything will work perfectly forever. However, even new systems need regular maintenance to ensure their continued performance. Many homeowners forget to schedule annual tune-ups, leading to reduced efficiency, higher energy costs, and the possibility of costly repairs.

How to avoid this mistake:

• Set up an annual maintenance schedule with a trusted HVAC contractor. Regular check-ups help keep the system clean, ensure proper refrigerant levels, and allow technicians to spot potential issues before they become more significant problems.

• Regular maintenance also extends the lifespan of your air conditioning unit and keeps it operating at peak efficiency.

Regular maintenance is a simple step that can prevent major issues and ensure that your AC unit continues to work for years.

Neglect Ductwork Issues

Your air conditioning system doesn’t work alone; it relies on your home’s ductwork to distribute cool air. If your ducts are old, damaged, or poorly designed, it can significantly reduce the efficiency of your new system. Leaky ducts or improperly sealed ones can result in uneven cooling, increased energy consumption, and even higher repair costs in the future.

How to avoid this mistake:

• Have your ducts inspected before installing a new AC unit. If they are old or damaged, they should be repaired or replaced.

• Consider upgrading to new, more efficient ducts that are properly sealed and insulated to prevent air loss.

Addressing ductwork issues before replacing your AC ensures your new system runs efficiently and your home stays cool.
