Efficiency ratings are regional, so the new HVAC regulations for 2024 depend on where you live. New air conditioners in Northern regions must have a minimum SEER rating of 14. In Southern regions, the minimum SEER rating is 15 for most units.
R-454B is the new refrigerant in 2024. By 2025, the EPA's required phaseout of R-410A will be in full effect, with production, importation, and distribution no longer allowed. HVACR businesses must be evaluating their current choices in coolant and ready to make the jump.
What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
2024 models are integrating air purification technologies to improve indoor air quality, including: UV-C Light Systems: Kill bacteria and viruses within the unit. Electrostatic Filters: Capture microscopic particles like allergens and dust. HEPA Filters: Remove up to 99.97% of airborne contaminants.
AC systems typically have a lifespan of 10 to 15 years. If your unit is approaching or has surpassed this age range, it might be time to consider a replacement. Older systems tend to be less reliable and more expensive to operate.

As Freon was phased out, new HVAC systems began using a refrigerant known as Puron® or R-410A, an HFC. More efficient and less harmful to the environment, R-410A has been in use since its introduction in 1996 and is found in most of today's modern HVAC systems.
When Will R-410A Be Phased Out Completely? The complete phase-out of R-410A will likely occur by 2036, when HFC consumption is expected to be reduced by 85%. However, businesses should prepare well in advance, as the restrictions beginning in 2025 will already limit its use significantly.
Several HVAC manufacturers have officially declared upcoming price hikes for 2024, garnering attention as a new wave of increases takes effect. There is a noticeable industry-wide trend of manufacturers elevating the prices of equipment, parts, and supplies.
If your system was installed in 2024 or beyond, it will likely use Puron Advance, also known as R-454B. Puron Advance has a low Global Warming Potential while also being non-ozone depleting.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
No. R-454B is NOT a drop-in replacement for R-410A. Although many of the characteristics of R-454B are similar to R-410A, the use of R-454B is restricted by code and regulation to systems for which it was specifically designed.
In new chiller production, HFC refrigerants like R-404A and R-410A are prohibited from 1st January 2024. The production of new equipment using R-22 ceased entirely in 2022, and the HCFC phaseout will be completed in 2030.
This move technically went into effect on January 1st, 2023, so it's already been a year. Under the DOE rules, US HVAC manufactures will discontinue production of SEER 14 units, and they can no longer sell any units with that rating, either.
The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B. Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a replacement for R-410A equipment. Its low density allows for the use of a smaller refrigerant charge.
Currently, the price for recharging an air conditioning system with R-410A is around $90 per pound.
R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single-component refrigerant.
R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing. R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
Freon™ MO29 refrigerant: Extends system life using the same equipment as R-22, so a system with an R-22 leak does not need to be completely replaced or upgraded. Offers similar capacity and efficiency as R-22.
2024 brought in some new rules around how efficient these systems need to be. The key one to know about is called SEER 2. It's just a new standard that makes sure air conditioners and heat pumps are up to scratch in terms of energy efficiency. The idea is to help reduce energy consumption overall.
Newton's law of cooling states that the rate at which an object cools is proportional to the difference in temperature between the object and the object's surroundings. Simply put, a glass of hot water will cool down faster in a cold room than in a hot room.
Central air cooling is the most cost and energy-efficient method for regulating temperatures in your home. All components of a central air system are outside, so you can enjoy a silent and secure way to cool your home.
