On March 29, the Occupational Safety and Health Administration (OSHA) issued its final “Walkaround” Rule that will have major implications for workplace inspections and, potentially, labor relations in the industry. OSHA's final rule expands the scope of who can participate in its workplace inspections. Notably, it permits unions and other third-party entities, which could include individuals with objectives contrary to the interests of the employer, to accompany OSHA inspectors. This change is part of a broader attempt by OSHA to amend the existing regulations regarding representatives of employers and employees during inspections. Key Points and Concerns: ...

This post was authored by Sean Robertson, ACCA's VP of Membership, Advocacy, and Events Contractors excited to inform their customers about the Inflation Reduction Act’s $8.8 billion in rebates for residential energy efficiency improvements may have to wait a little longer as states take a deliberate approach towards developing programs that will vary greatly from state to state . According to the U.S. Department of Energy’s application tracker , just four states – California, Hawaii, New Mexico, and New York – have submitted full applications. Allowing time for DOE review, possible revisions , and state procurement ...

Late last year, DOE finalized a rule prohibiting the sale of all non-condensing natural gas furnaces. This rule would impact over half of all US households by unnecessarily limiting consumer choice and raising heating costs. The rule particularly concerns those in colder climates who rely on gas furnaces for affordable heating and where electric heat pumps are not yet a viable alternative. It is currently set to take effect on February 16, 2024. Last week, Senator Ted Cruz and Representative Michelle Fischbach introduced S.J.Res.58 and H.J.Res.111, which would overturn this misguided rule. ACCA President & CEO Barton James was quoted in Senator Cruz's ...

Yesterday afternoon, the House of Representatives passed the Tax Relief for American Families and Workers Act (H.R. 7024) by a margin of 357-70. The bill allows for the immediate expensing of research and experimentation expenditures, reinstates the less restrictive “EBIT” cap on interest expense deductions, and restores 100-percent bonus depreciation, which is set to expire. The provisions in the bill are retroactive to 2022 and run through 2025. Another provision included in the bill is a significant expansion of the Child Tax Credit. The bill increases the cap on the credit’s refundability, expands eligibility, and links the credit’s value to inflation ...

The under the rule, the classification test includes six factors: The degree to which the employer controls how the work is done. The worker’s opportunity for profit or loss. The amount of skill and initiative required for the work. The degree of permanence of the working relationship. The ...

Last month, the Department of Treasury and IRS proposed regulations to implement product identification number (PIN) requirements for taxpayers who use the 25C residential energy efficiency tax credit. Under the proposal, beginning January 1, 2025, taxpayers claiming the credit must satisfy the PIN requirement for certain categories of products. Under this requirement, an item will only qualify for the energy-efficient home improvement credit if the item is produced by a qualified manufacturer and if the taxpayer includes the qualified PIN of the item on their tax return. The proposal contains more questions and solicitations for feedback from the industry ...

President Biden recently invoked the Defense Production Act (DPA) to accelerate the production of heat pumps. The DPA, primarily intended for national defense and security, is being utilized to compel American households to switch from gas to electric heating. The move raises concerns, as we believe applications of DPA should remain focused on its core purpose – promoting national defense and emergency preparedness, including infrastructure protection and recovery from terrorist attacks. In light of these developments, ACCA recently held a meeting with the House Energy and Commerce Committee Oversight staff. The aim was to express our concerns about the use ...

Earlier this month, ACCA submitted formal comments to the Department of Labor and OSHA opposing the recently proposed overtime and ' walkaround ' rules, respectively, that raise significant concerns for employers. Department of Labor's new overtime rule would raise the threshold for the white-collar/salary exemption to federal overtime pay requirements. Currently, an employee must meet three criteria to qualify as “exempt” from overtime pay: first, they must be paid a salary; second, that salary must be more than $684/week ($35,568 annually); and third, their “primary duties” must be consistent with executive, administrative, or professional positions as ...

Understanding COP

1 person recommends this.
As HVAC technicians, we often delve into the world of heat pumps, but do we really understand the full potential of the Coefficient of Performance (COP)? It’s not just a number; it’s a key diagnostic tool that can boost our service quality, reduce customer callbacks, and ultimately increase our revenue. Here’s how. What is COP? Put simply, it is a ratio of the heat energy transferred to the units of energy used. For context, resistance heat has a COP of 1:1, meaning it’s 100% efficient in converting electrical energy to heat. It’s essential to note that while resistance heating is 100% efficient at converting electricity into heat, it might not always ...
