The phase-out of R-22 has led many homeowners to consider replacing their units with systems that use a more eco-friendly refrigerant, like R-410A.

Heat pumps and A.C. systems are both designed to provide cooling during hot weather. However they work in different ways.

There are a few reasons why your heat pump may freeze in the summer. Low refrigerant or even dirty coils. Click here to find out more!

Don't vent any refrigerant into the atmosphere. Instead, properly dispose of it.

It is illegal to purge refrigerant into a bucket. It has to be properly and safely purged into a proper container.

The installation manual should tell you how many length of lineset a condenser is charged to handle. Additional refrigerant would be needed if those lengths were exceeded.

The most difficult part is properly charging the unit with the appropriate refrigerant amount. Some of our customers do the rough work themselves, then bring in a pro to charge the unit. That's definitely something we've had customers do, and do it successfully.

Why? Well, R410A works at a different temperature and a different pressure than R-22. If you don't change it then it's not going to boil off correctly. And when it doesn't boil off correctly, it means the refrigerant is going to return to the condenser mostly as a liquid rather than a saturated vapor. You don't want the liquid coming back. You want the vapor. 

You cannot legally vent R410A refrigerant into the atmosphere. Though it does not have high ozone depletion potential, it is a greenhouse gas so it is regulated by the EPA and they say don’t vent it into the atmosphere. If you do, then you have violated the Clean Air Act. 

They all have refrigerant in them so that when you connect them, they already have the refrigerant and you don’t have to vacuum the lines or charge the system during the installation.
