Thermostats / Standards & Legislation

ACCA, Others Oppose Thermostat Law

New Laws Could Lead to Big Problems, Industry Leaders Say

July 1, 2013

Despite vocal opposition from HVAC contractors, Trane, and the Texas chapter of Air Conditioning Contractors of America (ACCA), the Texas House and Senate recently passed a bill that allows licensed alarm system installers to install, repair, or replace thermostats and other temperature control interfaces.

The bill — which received significant support from several large home security and automation companies, including AT&T, ADT, and Comverge — will go into effect Sept. 1, once it is signed by the governor.

But the problem, according to industry leaders, is that many of these alarm system installers don’t have the appropriate training or knowledge to properly install or replace a thermostat, which can lead to system inefficiency, HVAC equipment failure, and even fire hazards.

And, with a similar piece of legislation currently making its way through the Michigan House and Senate, many worry the encroachment of home security companies on the HVAC industry may be an emerging — and disturbing — national trend.

Changing the Law

Todd McAlister, executive director for ACCA Texas, said the problems began about a year and a half ago, when he started getting calls from members and contractors who said they were having issues with home automation companies incorrectly installing thermostats.

“All they thought they had to do was plug and play the thermostat,” McAlister said. “What was happening is they were blowing the transformer or blowing the fuse in the furnace or air handler so the blower wouldn’t turn on. The customer was caught in the middle.”

McAlister said they took their concerns to the Texas Department of Licensing and Regulation, then “put together legislation that said, ‘We see the value of home automation, but these installation companies need to be using a licensed contractor to make sure things are the way they’re supposed to be when that thermostat is installed.’”

But AT&T did not like the legislation, and filed their own bill that modifies existing requirements pertaining to HVAC licensure by removing “the installation, repair, replacement, or modification of a thermostat or other temperature control interface” from the definition of “air conditioning and refrigeration contracting.” The change allows alarm system installers who are licensed under the Texas Private Security Act to install, repair, replace, or modify a thermostat.

Though ACCA Texas and others fought the legislation, it passed in both the House and Senate in late May and is currently awaiting Gov. Rick Perry’s signature.

Dangerous Consequences

The biggest problem with the Texas legislation, McAlister said, is that it puts consumers at risk.

“This is bad for homeowners — this is not good for anybody,” he said. “We have a contractor out of Longview, Texas, who sent us some documentation and a picture of an unlicensed contractor who installed the thermostat incorrectly and caught the house on fire.”

McAlister added that, should anything go wrong with the HVAC system because of the thermostat installation, an installer who is not HVAC certified may not notice right away, and if they do, they would be required to call in an HVAC technician to take care of it, anyway.

“You would think that logic would win over, and if a telecom company wants to be in this industry, then they should go get an HVAC license so there’s at least some credibility in what they’re doing,” he said.

Charlie McCrudden, vice president of government relations for ACCA, echoed McAlister’s concerns.

“There are a number of companies that install thermostats that coordinate with the home security system package,” he said.

“The alarm industry is sort of moving from putting in home alarms and building alarms to services that would encroach on energy use of the home.”

He added, “It’s no accident, and I wouldn’t be surprised if we see this popping up in more states.”

AT&T Responds

Rossanna Salazar, spokesperson for AT&T Texas, said her company’s alarm system installers are more than capable of properly installing thermostats as part of AT&T’s new Digital Life wireless home management security system.

“Our authorized digital life technicians are licensed as Texas alarm system installers and must pass a state of Texas background check as a condition of receiving their license,” she said, adding, “It is important to note that Texas homeowners are able to walk into any home improvement or hardware store, buy a thermostat, and change it out themselves.”

Salazar said opponents of the legislation “have made many claims that have confused the policy debate,” especially when it comes to the manufacturer’s warranty on HVAC equipment.

“The issue of licensing has nothing to do with the warranty issue. Just because a homeowner — or anyone — installs a new thermostat does not mean that they will lose or even jeopardize the full warranty on their system. If there is something wrong with the indoor air handler or the outside compressor, it will still be under warranty.”

Salazar added that some manufacturers will not cover damage caused by a third-party component, including an after-market thermostat, regardless of who installed it.

“If a person’s air conditioning system is under warranty, he or she should check to be sure that any new thermostat is compatible with that system,” she said.

Industry Voices Concerns

McCrudden agreed with Salazar that installing improper equipment could void a manufacturer warranty, though he said it is all the more reason to hire a certified HVAC technician.

“Some of the manufacturers do require that the equipment be installed to code or to local law, and if that requires contractors to install the thermostat, that could potentially void the warranty,” McCrudden said. “Also, if you don’t know what you’re doing, you could damage the equipment, or it may cause a fire hazard.”

Francis Dietz, vice president of public affairs for the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), said some of their members are also concerned about the issues that could arise from allowing alarm system installers to install thermostats that are incompatible with the customer’s HVAC system.

“This could be an issue, not necessarily with respect to warranties, but definitely with respect to comfort and energy savings,” Dietz said. “Replacing a thermostat that controls a high-end, multistage unit with a noncommunicating one would likely cause the unit to operate as a single-stage unit, sacrificing comfort and energy efficiency for the homeowner.”

Dietz added that AHRI “would urge consumers who have multi-stage systems, or those that involve add-ons such as humidifiers or dehumidifiers or zoned systems, to consult a reputable service technician prior to allowing anyone to make any changes to their thermostats.”

ACCA Michigan executive director Ron Sandelius, who is currently fighting legislation in Michigan that would allow a registered system provider or licensed security alarm system contractor to install a thermostat without having to obtain a license or permit, said he is also concerned that someone who is not properly trained will not be able to choose the correct thermostat for the system.

“While they may understand how a basic thermostat operates, they may not make the best selection that will provide the most efficient operation of the equipment and its additional related functions, such as humidification, dehumidification, air purification, temperature averaging, and zoning, to mention a few,” Sandelius said.

“If damage occurs due to improper or incomplete selection of the thermostat and its accessories, who will be liable for the repairs?”

A beautician should never be allowed to perform medical surgery on anyone. Likewise, a Home Security or Automation company should not be allowed to modify or meddle with the mechanics of refrigeration. A thermostats can be 12V, 24V, 120V or 240V; single or multi-staged, digital or mechanical, low or high powered controls. It can also be physically wired for winter or summer controls. It can be wet or dry contact which controls the systems and it can also sense remotely or locally. If an installer is not well versed with different systems especially those with options from other countries, the whole system can eventually be damaged. The newer ductless, wall mounted or ceiling cassette systems will not allow any introduction of external thermostats since the electronically controlled accuracy is less than 0.3 degree Celsius. With the introduction of inverter compressors into the field, there is no substitute for originally manufactured temperature controlled systems. The Japanese guards their own proprietary systems very jealously. At most, the Automation companies should be allowed to interlock or switch on/off the systems. More than that, chances of frying Printed Circuit Boards or control wirings will be really big. This is no laughing matter.
