AC and Heat Pump Efficiency Standards: What SEER2 Means for Wichita Homeowners

When you replace a central air conditioner or heat pump, the equipment has to meet federal minimum efficiency standards set by the U.S. Department of Energy (DOE). The current minimums took effect on January 1, 2023, and they changed both the required ratings and how those ratings are measured.

SEER2: the current rating

SEER stands for seasonal energy efficiency ratio. It rates how much cooling a system delivers for the electricity it uses, and a higher number means a more efficient system. Since 2023, equipment is tested under a newer procedure and rated in SEER2. SEER2 numbers read lower than the old SEER numbers for the same equipment, so a 13.4 SEER2 system performs about like a 14 SEER system under the old method. Compare SEER2 to SEER2 when you shop.

Minimums depend on where you live

The DOE sets different minimums by region. Kansas is in the northern region, where split-system central air conditioners must be at least 13.4 SEER2. The southern regions have higher minimums for most sizes. Split-system heat pumps must be at least 14.3 SEER2 and 7.5 HSPF2 (the heating-efficiency rating) in every region.

What it means for you

An existing system that was legal when installed can stay in service. The standards apply to new equipment.
When you replace a system, the new equipment must meet the minimums for its region. Many models exceed them.
A higher SEER2 rating generally lowers operating cost, so it is worth comparing models for the system you plan to keep a long time.
Rating is not the only factor. Proper sizing, ductwork condition and installation quality affect how efficient a system is in your home.

A note on refrigerants

Manufacturers have been moving new residential equipment away from R-410A refrigerant toward lower-impact A2L refrigerants such as R-454B. Ask which refrigerant a system uses and what service it will need.

I contacted Midwest Mechanical for a winter Service Tune-Up of my Gas Furnace before I was going to fire it up with the coming cold weather, and taking advantage of their Special Tune-Up price. It's a super price for the service they provide. The Service Technician was thoroughly knowledgeable of my furnace and made all the inspections and cleaning of parts on the furnace that could have cost more down the road if they were not done at this juncture. For the price of a simple Tune-Up, I received a full inspection and cleaning that would have cost more at other HVAC companies. The Technician, Angel, took the time to explain the work he was doing and how the company's goal is to help customers save money. Midwest got me on the schedule with very little notice. I highly recommend Midwest Mechanical for any mechanical needs your home might have, whether it be HVAC, Plumbing, or Electrical. I am glad I called Midwest and plan to use their services again in the near future. Professional and affordable!
