Being proactive about your air conditioner's warranty can lead to smarter financial decisions, preventing unexpected repair costs.

Examine the Refrigerant Type

Understanding refrigerant types is key when examining your air conditioner. Older air conditioning units likely use R22 refrigerant, which has been phased out in the U.S. since 2020 due to environmental concerns. Replacing R22 with modern refrigerants like R-410A is costly and challenging because R22 supplies are dwindling and prices are rising.

Modern air conditioners use R-410A, which is more energy-efficient and environmentally friendly. However, starting in 2025, manufacturers will switch to newer refrigerants such as R454B or R-32. This transition will be gradual, ensuring enough R-410A is available for existing systems.

Here's how refrigerants compare:

When deciding whether to service or replace your air conditioning system, consider the type of refrigerant it uses. If you have an R22 system, upgrading to a unit that uses R-410A or newer refrigerants can save on energy bills and help the environment.

Determine Home Comfort Satisfaction

Determining home comfort satisfaction involves evaluating your air conditioning system's performance. A key factor is whether you're facing frequent repairs, as this often means your system's efficiency is dwindling. Modern air conditioning units, if chosen wisely, can last over fifteen years.
