Factors to Consider Before Replacing Your Air Conditioning Unit

If you're considering replacing your air conditioning system in Taunton, there are a few factors to consider before making a decision. Here are some important things to keep in mind:

  1. Age of your current AC system: If your air conditioning system is more than 10-15 years old, it may be time to replace it. Older systems are less efficient and may require frequent and costly repairs.
  2. Overall energy efficiency: Newer air conditioning systems are more energy-efficient and can help you to save money on your energy bills. Look for systems with a higher SEER (Seasonal Energy Efficiency Ratio) rating, which means they use electricity.
  3. Repair costs: If you're facing frequent AC repairs and the costs are adding up, it may be more cost-effective to replace your air conditioning system. A new AC unit will come with a warranty and typically be less likely to require repairs in the very near future.
  4. Comfort and air quality: If your current system isn't keeping your home comfortable or is producing poor air quality, it may be time for a new unit. Newer systems have advanced features, such as zoning and air filtration, that can improve comfort and air quality.
  5. Choosing the proper size unit: It's important to ensure that your new air conditioning system is the right size for your home. An HVAC professional from Cotti-Johnson can perform a load calculation to determine the appropriate size for your specific needs.

If you're in Taunton or the surrounding area and considering a new air conditioning unit, contact Cotti-Johnson for a professional estimate. Our experienced AC technicians can help determine the best option for your home and get your new unit installed properly.

Common Mistakes to Avoid When Replacing Your AC Unit

It's essential to replace your AC unit the right way the first time to avoid costly mistakes, such as:

  • Not considering the size of the unit: One of the most common mistakes people make when replacing their air conditioning system is not considering the size of the unit. Installing an oversized or undersized unit can lead to inefficiency, discomfort, and increased energy bills.
  • Not hiring a professional: Replacing an AC unit is a complex job that should only be handled by a professional. Hiring experienced and licensed HVAC technicians from a company like Cotti-Johnson can ensure that the installation is done safely and correctly.
  • Failing to consider your ductwork: The condition of your ductwork can impact the overall efficiency and effectiveness of your new air conditioning system. It's important to have your ductwork inspected and, if necessary, repaired or replaced before installing a new unit.
  • Not budgeting for the project: HVAC units can be a significant investment. Make sure you budget for the project, including the cost of the unit, installation, and any necessary upgrades or repairs. We also offer financing options to our customers to help ease the burden of unexpected costs.

By avoiding these common mistakes, you can help to ensure that the installation goes smoothly and that you enjoy the benefits of a reliable new AC system for years to come.
