Facts About Converting Your R-22 HVAC System To One That Uses R-410A Refrigerant

by Louise Moore

Because of the impact R-22 refrigerant has had on the ozone layer, the Environmental Protection Agency (EPA) has taken steps to completely phase it out. Many people that currently have HVAC systems still using R-22 are considering having their systems converted to use the new, safer refrigerant, R-410A. Converting your HVAC system is not the typical DIY project. When it comes to making this conversion, learn the reasons why you will need to call an HVAC professional for getting it done. 

Conversion Entails Major System Changes

When converting an R-22 HVAC system to one that used R-410A, major system components will need to be changed out. The condenser, compressor, expansion valves and evaporator that are in your system use only R-22, so all these parts will need to be replaced with ones that use R-410A. R-410A will not work in existing components design for R-22 because it has a higher pressure. System parts for R-410A have a thicker design.

Copper Lines Can Be Reused If They Are Completely Dry

The copper lines in your HVAC system can be used for R-410A if they can be flushed out and completely dried. If any condensation is left inside the copper tubing, it can cause a breakdown in the R-410A refrigerant. When professionals flush and dry out the copper tubing in your HVAC system, it will also be a time to locate any leaks before charging up your system with R-410A.

Conversion Will Need To Take Place At One Time

If you have considered having one part at a time installed in your HVAC for converting to an R-410A system, you should know it would not be wise. R-22 and R-410A refrigerants require the use of incompatible lubricating oils and R-410A will damage the parts in your system design for R-22. Having all the vital components in your HVAC system should be changed out at the same time. If you are trying to get the job done when you have the money, you might think about sticking about saving up the cash to have the whole system done at one time.

Up Until The Year 2020

According to the timeline published by the EPA, homeowners have until 2020 before R-22 is completely phased out. Having your system overhauled before that time is the best way to avoid having to save the money while your system is down.  

Avoid being without heat or cool air when you need it the most by checking into HVAC system conversion today. Discuss the needs your system has with a qualified HVAC professional (such as one from Controlled Comfort) before taking steps to convert your system on your own.

Learning About Old and New Furnace Options

Hi there, my name is Marissa Sonder. I would like to use my site to talk about the different types of furnaces available for residential and commercial applications. Growing up, my school had an actual boiler room that provided heat and hot water for the entire building. All of the students loved to go down to the boiler room and learn about all of the components down there. Although many buildings have moved on from this old piece of equipment, I would like to discuss its use in detail on this site. I will also talk about modern electric, natural gas, propane and oil furnace systems. Thanks for coming by.
