DIY Guide: Should You Purchase An AC Replacement? 

Aug 8, 2024

When your air conditioner encounters issues, the big question often is whether to repair the AC unit or replace the AC system entirely. This decision can be challenging, especially when faced with a high repair quote. Let’s explore the factors that will help you determine whether to repair or replace your AC. If you find the process too complicated, remember that FAST HVAC is just a call away for fast and reliable services. 

Understanding the 50% Rule for AC Replacement 

Firstly, let’s apply the 50% rule. If the cost to repair the AC is half or more than the price of a new unit, it might be more cost-effective to replace it. This rule is based on the consideration that extensive damage often indicates that the AC is nearing the end of its useful life. 

The Lifespan of Air Conditioners 

On average, air conditioners have a lifespan of 10 to 15 years. Regular maintenance can extend this, but it’s wise to start considering AC replacement as your unit ages. This proactive approach helps avoid the sudden need to replace the AC when you least expect it. 

Special Cases: When AC Repairs Are Worthwhile 

However, there are situations where it’s better to repair the AC. If your AC is relatively new and suffers an unexpected breakdown, a repair might extend its life significantly. In such cases, consulting with an HVAC expert is essential to decide whether to repair or replace the AC. 

Considering Energy Efficiency in AC Replacement 

Another key factor is energy efficiency. Upgrading to a more energy-efficient model might be a smart move. While the initial cost to replace the AC might be higher, the long-term savings on energy bills can be substantial. 

Making the Decision: Repair or Replace? 

Deciding whether to repair or replace the AC depends on various factors, including repair costs, the age of your unit, and energy efficiency. Here’s a simple checklist to help you decide: 

  • Cost of Repair: Is the repair cost 50% or more of the replacement cost? 
  • Age of the Unit: Is your AC over 10 years old? 
  • Frequency of Repairs: Have you had multiple repairs in the last few years? 
  • Energy Efficiency: Would a new unit offer significant energy savings? 
  • Performance: Is your current AC meeting your cooling needs? 

Required Tools for DIY AC Maintenance 

Before making a decision, you might want to try some basic maintenance tasks to improve your AC’s performance. Here are some tools you might need: 

  • Screwdriver Set: For opening panels and accessing internal components. 
  • Soft Brush: For gently cleaning the coils. 
  • Vacuum Cleaner: To remove dust and debris from around the unit. 
  • Replacement Filters: To swap out dirty or clogged filters. 
  • Fin Comb: To straighten any bent fins on the condenser and evaporator coils. 
  • Thermostat Batteries: In case the thermostat is not functioning due to low battery. 

DIY Maintenance Tips 

Once you have the necessary tools, you can follow these steps: 

  1. Check and Replace Filters: Dirty filters can reduce efficiency. Replace them regularly. 
  1. Clean the Coils: Dust and debris on the coils can hinder performance. Clean them gently. 
  1. Inspect the Thermostat: Ensure your thermostat is working correctly and set to the right temperature. 
  1. Clear Debris Around the Unit: Keep the area around your outdoor unit clear of leaves, dirt, and other obstructions.
