R-22 Conversions in Baltimore, MD

Due to environmental concerns, R-22 Freon is no longer manufactured in the United States. Older cooling systems that rely on this harmful refrigerant must be converted to be compatible with safer alternatives.

United Air Temp is ready to help with your R-22 conversion, offering expert guidance and solutions to ensure your systems are upgraded seamlessly and compliant with regulatory standards.

With upfront pricing and a commitment to quality craftsmanship, we’re confident in our ability to deliver safe solutions that keep your home comfortable for the long term.

Request an R-22 conversion for your AC system by calling today.

What Is Refrigerant?

Refrigerant is a key component of many HVAC systems, facilitating the heat transfer necessary for cooling in central air conditioners, ductless mini-splits, and heat pumps. It cycles through the system, absorbing heat from the indoor environment and releasing it outside during cooling. This process is reversed for heating in the case of ductless mini-splits and heat pumps.

There are many types of refrigerants, each with distinct properties and environmental impacts. However, R-22 Freon, once widely used, is no longer manufactured due to its ozone-depleting properties. This phase-out has led to the adoption of more eco-friendly alternatives, ensuring both efficiency and environmental compliance.

What to Expect From an R-22 Conversion

Retrofitting an existing HVAC system to accommodate alternative refrigerants is done through the following process. Your technician will:

  • Recover the old R-22 refrigerant
  • Thoroughly clean the system to remove any residual traces of R-22 Freon
  • Inspect and replace seals, gaskets, and the compressor as needed
  • Recharge the system with the alternative refrigerant
  • Test the retrofitted unit to verify proper operation and efficiency

We do everything possible to ensure a smooth transition and continued reliability for your HVAC system.

Alternative Options for R-22 Systems

Conversion may not be the best solution for your R-22 Freon-reliant system. There are two other options to consider:

Recharge Your HVAC System with R-22

Some homeowners may wish to keep their R-22 HVAC equipment, recharging with the discontinued refrigerant.

While this is still a viable option, it can get expensive as the U.S. stopped importing and manufacturing R-22 Freon on January 1, 2020. You’ll need to use stockpiled and recycled refrigerant, which is much costlier than other refrigerants.

Replace Your HVAC System

While R-22 conversions are possible for existing HVAC equipment, they may not be the most cost-effective option for systems approaching the end of their lifespan.

If your comfort system is more than 10 years old, it may make more financial sense to replace your air conditioner rather than convert your existing system.

Request R-22 Conversion With United Air Temp

Frequently Asked Questions

Hydrochlorofluorocarbons (HCFCs) are a group of chemicals used in refrigeration and air conditioning. R-22 is a common HCFC refrigerant known for causing ozone depletion.

You can check if your AC uses R-22 Freon by looking at the nameplate on the outdoor condenser unit, which typically lists the type of refrigerant used, or by consulting the unit’s user manual.

Common replacements for R-22 Freon include R-410A Puron, R-407C Freon, and other environmentally friendly refrigerants that don’t deplete the ozone layer.
