The legal wrangling over the DOE regional efficiency standards
has taken on the air of a day time soap opera, or reality TV. We can call our new program "HVACR Survivor." The May
implementation of the regional efficiency standards will be delayed while a
legal case works its way through the courts. On May 1 2013, furnace
efficiencies were scheduled to start following the ruling.
Under this scenario, non-weatherized furnaces in the northern region of the
country would have to be a minimum of 90% AFUE. However, the American PublicGas Association (APGA) filed suit against the ruling(APGA suit). The DOE and APGA reached
an agreement that would vacate the non-weatherized gas furnace and mobile home
gas furnace standards and start the process over to develop a new standard (DOE APGA agreement). The
rest of the standard would remain in tact. However, the agreement has to be
accepted by the court to go into effect. Heating, Air Conditioning,
Refrigeration Distributors International (HARDI) filed a motion with the court
to not allow the settlement, and instead, allow HARDI to replace APGA in the lawsuit (HARDI motion).
HARDI would like the entire process to start over, not just the part with the
furnaces. Since there is a real possibility that this will not be resolved
prior to May 1, the DOE has sent out letters stating that it does not intend to
enforce the rule pending the court ruling(DOE letter). So for the immediate future, you can
still buy an 80% AFUE furnace up in Wisconsin if you want. Whether or not that
is a wise thing to do is a topic for another debate. For now, we will just have
to wait to see who is voted off the island. Below is an overview of the
Regional Efficiency Standards in their original form.
Regional Efficiency Standards Overview
The Federal Department of Energy, DOE, issued a direct final
ruling on furnace and air conditioner efficiency in October of 2011. The ruling
breaks the country into three regions: North, Southeast, and Southwest regions.
A map can be seen at http://www.achrnews.com/ext/resources/NEWS/Home/Images/ApplianceStandards-map-BIG.gif
In a nutshell: in the Northern region furnace efficiency
will increase while heat pump and air conditioning efficiency will remain the
same; in the Southeastern and Southwestern regions furnace efficiency will
remain the same while heat pump and air conditioning efficiency will increase.

The increased standards will be phased in over a period of
years. Compliance with the standards in the direct final rule will be required
on May 1, 2013 for non-weatherized furnaces and on January 1, 2015 for
weatherized furnaces, central air conditioners and heat pumps. Industry
reaction has been split. AHRI helped to develop the standards and supports
them. They want to avoid the confusion and cost that was associated with the 13
SEER efficiency change that gave the industry very little time to prepare. (looks
like we already blew that) AHRI also points to the Canadian experience when
they mandated 90% . Their sister organization, HRAI, has stated that there were
very few problems with Canada’s implementation of 90% standards. ACCA opposes
the standards , especially the 90% furnace mandate, concerned that the extra
cost will drive customers to illegal contractors, who feel no compulsion to
follow the rules and will cheerfully install equipment that legitimate
contractors are not allowed to offer. HARDI also opposes the regional standards,
citing the difficulty this will make for distributors who service two or more
regions. ACCA and HARDI also cite that there is currently no enforcement
mechanism – no DOE police. Again, the problem is that contractors who don’t
abide by the ruling achieve a competitive advantage over contractors who do.
Thanks for sharing this post with us. It’s quite informative and covers all the problems that generally occur. It is essential to schedule a HVAC Service Plantation, FL to take good care of the HVAC.
ReplyDeleteIf anyone wants an HVAC contractor i must recommend DeepClean NL Ltd.
ReplyDeleteI just recently hire them for Air Exchanger Cleaning and they did amazing job.
