Our Recommendation For a split system, use matching equipment from the same manufacturer. Do not mix and match. Yes, technically, you might be able to get them to work, but it's an absolutely terrible idea for a lot of reasons. Just don't do it!
It would be fine to mix and match brands, as they all work basically the same. However, the outdoor unit (condenser) and the indoor coil need to be the same tonnage. The company you have installing should be able to match that up for you and get you the right unit.
The $5,000 rule is a rule of thumb in the HVAC industry to help homeowners decide whether HVAC repair or HVAC replacement makes more sense in the long run. The $5,000 rule: Multiply the age of your equipment by the estimated repair cost. If the number is more than $5,000, then you should consider replacing your unit.
No you can't mix refrigerant. Systems are designed for specific temperatures and pressures and the compressor oil is also specific to the refrigerant type.
Yes brands are interchangeable, however not all ac units will work well with your furnace. For example if your current furnace is a basic single stage and a contractor wants you to buy a two stage AC system this would be a waste of money because your system wouldnt work to it's full potential.
In the worst circumstance, the incompatible system may not function at all. Or, it may seem to operate initially and then break down after some time. In all circumstances, the machine's efficiency and longevity will be compromised.
Same brand preference: It is generally recommended to stay loyal to one brand when selecting a manufacturer for your heating and cooling systems. While some brands allow system mixing as a viable option, it is not guaranteed that different brands pair well together as systems of the same brand.
What Happens to Your AC System if You Mix Refrigerants? Mixed refrigerants can cause increased system pressures and temperatures changing them for the worse. This can result in ineffective compressor cooling and possible compressor damage, ineffective cooling, and metering device malfunction.
The refrigerant is usually the same, although some places will add oil and dye in differing quantities.
Mixing refrigerants is not an option either. This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires.
It's important to be aware of how long air conditioners last, so you don't get the unwelcome surprise of a broken air conditioner in the peak of the summer heat. In general, air conditioners that are properly maintained can last 15 to 20 years.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
The New Regulations
Starting January 1, 2025, all new residential air conditioners and heat pumps must utilize A2L refrigerants. Older refrigerants like R-410, which are likely the refrigerant used by your current system, are being phased out.
Your air conditioner's indoor and outdoor units must be designed to work together. Mismatched air conditioning systems are more than 30% less efficient and can cause undue stress on the entire HVAC system.
The brand does matter when you purchase a new HVAC system for your home. However, as long as you purchase a top-tier brand, the differences between those brands are small. Our preferred brand at J&W Heating and Air + Plumbing is York, but we also install Carrier, Daikin, and Trane, to name a few.
The main two will be R-22 and R-410A which are also known as Freon and Puron respectively. The two types of refrigerants are not interchangeable within a system, so you want to ensure you choose the right one before purchasing your system. There are some other very important differences between the two refrigerants.
The different types of refrigerants are not meant to be mixed. The refrigerant charge must be optimized by using the refrigerant's respective pressure-temperature chart.
The AIM Act is a Federal nationwide rule phasing out the use of global warming materials. As part of that effort, EPA is now banning the use of 134a in aerosol products as of 1/1/2025. There are excepted products that are allowed to use 134a until 1/1/2028.
R-32 is the most balanced refrigerant in terms of environmental impact, energy efficiency, safety, and cost-effectiveness. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.
It is not only uneconomical and impractical to mix different types of refrigerants, but it can also be dangerous. Along with that, it is illegal to mix refrigerants. So, not only does it make sense to use the right kind of refrigerant for your system, but it's also the law.
Choosing the wrong one will damage system components. Avoid Leaks: Minor mistakes made when replacing Freon can cause leaks, impair system cooling efficiency, or result in a complete system failure.
You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you're not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.
In short, the answer is, "No!" Automotive refrigerants are volatile compounds that can have a negative effect on the environment. Combining them can have adverse effects, and cause damage to your car's A/C system.
Typically, using different brands has no major negative consequences. The key is to properly size the unit and make sure the coils, blower and wiring are compatible.
Yes, not all manufacturers of heating and cooling equipment are created 100% equal. Different brands focus on incorporating the latest and greatest technologies to improve how long their systems can last, and some companies stand behind their systems with stronger warranties.
