The short answer is yes, for a lot of reasons. The industry is changing dramatically with new Government regulations that have been coming down the pipe for years. Take the time, while your system is running, to discuss what we never want to talk about… system failure.
The refrigerant we have been using for the last 20+ years has been banned from any new systems being manufactured after Jan 1, 2025.
Having said this, if your system is a year or older, the refrigerant R410a it probably uses is on its way out and will eventually become very expensive to service your system with.
The residential industry has 2 NEW refrigerants now to install in only NEW systems R454b and R32. Both have pluses and minuses, but both are the only viable choices we have for now.
More importantly, they cannot be used in your existing system.
We used to be able to change out either the inside or outside units individually, and make them work well enough, but those days are now gone. With a few exceptions, residential systems will have to be changed as a SYSTEM, inside and out, at the same time, to get an approved match. This means a higher replacement cost for your comfort.
So… having your system checked and cleaned now will help you with information on the timeline you have with your existing system. This is very important to know since this is one of the most expensive repairs in your home you will encounter. Systems in the South have a “typical” life expectancy of about 12-15 years before needing to be replaced.
At the very least, have the outdoor coils cleaned and clear the bushes, trashcans etc. away so it can dissipate the heat freely to the outdoors. On the inside unit, pull the filter(s) out and replace them so the system can more efficiently remove the heat from your home.
With newer and higher efficiency systems being installed, discuss Surge Protection and Voltage monitoring as an option with the new system. New electronic controls and circuit boards are more susceptible to Voltage issues and Lightning much more than older systems.
Ductwork is more critical than ever as well… another large and NEEDED expense.
Don’t wait until it is too late to make an informed decision on a large expenditure, talk with a trusted HVAC contractor and get a plan for the inevitable system failure.
Key Takeaways:
- Refrigerant Phase-Out: The refrigerant R410a, common in systems a year or older, is being phased out. After January 1, 2025, new systems will use R454b or R32. Servicing older systems with R410a will become increasingly expensive.
- System Replacement: Due to new refrigerant types, you can no longer simply replace an indoor or outdoor unit. Most residential systems will need to be replaced as a complete “system” (both indoor and outdoor units) to ensure compatibility and approved operation. This will lead to higher replacement costs.
- Maintenance is Crucial: Regular checks and cleaning can extend the life of your current system. This includes:
- Cleaning outdoor coils and clearing surrounding bushes.
- Replacing air filters in the indoor unit.
- Lifespan: HVAC systems in the South typically last 12-15 years.
- New System Considerations:
- Surge Protection and Voltage Monitoring: Newer, high-efficiency systems have sensitive electronic controls that are more vulnerable to voltage issues and lightning. Discuss these protection options with your contractor.
- Ductwork: Proper ductwork is more critical than ever with newer systems and can be a significant, but necessary, expense.
- Plan Ahead: Don’t wait for a system failure to make decisions. Consult a trusted HVAC contractor to develop a plan for the eventual replacement of your system.
