(Feature Impact) Stretches of scorching summer days may leave you and your family feeling like you just can’t quite get (or stay) cool. If you find yourself resigned to cooler rooms or leaving ceiling fans on constantly, it might be time to check your air conditioner.

Extreme heat is no longer rare for many parts of the country. According to recent data from the U.S. Census Bureau, more than 13 million households reported being uncomfortably hot for an extended period.

Not all air conditioning systems perform the same when temperatures spike. While most systems can keep up on typical summer days, prolonged heat can expose performance gaps, leading to uneven cooling and higher energy use. The difference often comes down to how the system is designed.

To better understand whether your HVAC system can stand up to summer, consider this information from the experts at Mitsubishi Electric Trane HVAC US (METUS), a world leader in residential air conditioning units with sophisticated, durable systems that deliver quiet operation and energy-efficient performance.

Why Some Homes Stay More Comfortable Than Others

Not every home experiences summer heat the same way. Factors such as home layout, sun exposure, insulation, and HVAC system design can all influence how effectively a home maintains comfort during prolonged periods of high temperatures.

For example, upstairs bedrooms, rooms with large windows, and spaces exposed to direct afternoon sun often have different cooling demands than other areas of the home. Systems that provide more precise temperature control and flexibility can help address these differences and deliver more consistent comfort throughout the house.

Signs Your System May Be Struggling

As summer temperatures rise, there are often clear signs that an HVAC system may be struggling to keep up with demand. One of the most common indicators is a system that seems to run constantly during the hottest parts of the day, yet fails to deliver the level of comfort homeowners expect.

Homeowners may also notice persistent warm spots in certain rooms, increased indoor humidity, or weaker airflow from vents. In some cases, increased noise from vents or equipment may signal the system is working harder than usual to maintain airflow and cooling performance.

Another warning sign often appears on monthly utility statements. A noticeable increase in energy use during peak summer months can indicate the system is consuming more power to maintain comfort under challenging conditions.

What Makes the Difference in Extreme Heat

Not all HVAC systems are built the same. Modern system design plays a critical role in how well a home stays comfortable during prolonged high temperatures. Zoned Comfort Solutions from Mitsubishi Electric include ducted and ductless options designed to deliver reliable comfort, efficiency, and control in demanding conditions like summer heat surges, along with important features like:

• Cooling performance designed to maintain comfort even during extreme outdoor temperatures
• Precise temperature control that helps deliver more consistent comfort throughout the home
• Quiet, efficient operation that delivers strong performance with less noise and energy use
• Flexible installation options for homes with existing ductwork and homes without ducts, plus room additions, garages, sunrooms, and other hard-to-cool spaces

Evaluating whether your current system is designed to handle sustained high temperatures can help prevent discomfort and avoid rushed decisions during the hottest days of the year. To learn more, visit MitsubishiComfort.com.

(Feature Impact) Shoppers are paying closer attention to the products they bring into their homes. They want to know what ingredients are used, how items are packaged and whether the production process includes thoughtful choices. Beauty brands are taking note, and sustainability is increasingly shaping decisions across sourcing, packaging, production, shipping, storage and replenishment.

Responsible product lines rarely come from sweeping change. They are built through smaller, connected choices made throughout development. Packaging, ingredient sourcing and production planning influence how a product performs, how much waste it creates and how sustainably products can be produced.

Consider this beauty sustainability information from Laura Badcock, Chief Operating Officer of NourishUs Naturals.

Why packaging matters beyond appearance

“Packaging is often the first thing shoppers notice,” Badcock said. “It can shape how someone feels about a product before they ever try what’s inside.”

A package should look appealing, though appearance is only part of the equation. It also needs to protect the product, travel safely, store well and hold up through regular use. Once the product is finished, the packaging should allow easy recycling, refilling or responsible disposal.

There is no single packaging option that works best for every beauty product. A lightweight container may reduce shipping weight. A refillable option may stay in use longer. A recyclable material may work well in one area but create challenges in another if local recycling systems cannot process it. Even packaging that appears sustainable can create problems in practice if it leaks, breaks or requires excess shipping materials.

Why ingredient sourcing matters

“Ingredient lists have become an important part of how people evaluate beauty products,” Badcock said. “Shoppers often look for familiar oils, butters, botanical extracts and information about how ingredients were sourced, which plays a major role in the environmental impact.”

A product’s environmental footprint is influenced by many factors, including shipping distance, processing methods, storage conditions and supplier practices.

These factors can also affect product consistency and ingredient availability over time. Beauty brands working with wholesale skin care suppliers or private label manufacturers often need to balance ingredient goals with sourcing reliability and production needs.

How better planning can lead to less waste

“Packaging and ingredients are usually the first things people associate with sustainability, but how much product gets made, stored and discarded matters, too,” Badcock said.

Overproduction is one of the biggest hidden sources of waste in beauty and personal care. Products that sit too long in storage may eventually expire or remain unsold. Excess inventory can also create additional packaging waste, warehousing needs and disposal costs.

Smaller batch sizes give producers more room to adjust as trends or demand shift, and producing closer to expected sales windows helps reduce long storage periods and unnecessary waste. Testing new products in smaller volumes and restocking based on actual demand makes overproduction less likely.

How sustainable beauty choices are connected

Packaging, ingredient sourcing and production planning are closely connected throughout development.

“A packaging choice can affect shipping weight, storage needs and whether a package can be refilled,” Badcock said. “Ingredient choices can influence sourcing timelines and how products need to be stored. Production planning affects how much material gets used and how much product could eventually go unsold.”

Beauty shoppers want more transparency around sustainability claims

Sustainability claims carry less weight when those claims aren’t explained in practice.

This shift is pushing many beauty brands to focus more heavily on traceability, supplier relationships and clearer product information. Transparency is becoming part of the customer experience itself.

More responsible product lines are built over time

Responsible beauty products come together through ongoing choices around packaging, sourcing, production and inventory planning. For shoppers, those choices influence the products they bring into their homes.

“The brands that build sustainability into early decisions tend to have the easiest time maintaining it later,” Badcock said. “Once supplier relationships, packaging formats and production routines are in place, small adjustments are far easier than major changes. Treating sustainability as part of product development from the beginning, rather than something to fix later, is what makes it work in practice.”

The U.S. government is in full retreat from its efforts to make vehicles more fuel-efficient, which it had been prioritizing, along with state governments, since the 1970s.

The latest move came on Feb. 12, 2026, when President Donald Trump and the Environmental Protection Agency issued a new rule rescinding the landmark “endangerment finding,” and reversing various emissions limits on cars and trucks. The 2009 finding stated that greenhouse gases pose a threat to public health and welfare. If the new rule stands up in court and is not overruled by Congress, it would undo a key part of the long-standing effort to limit greenhouse gas emissions from vehicles.

As a scholar of how vehicle emissions contribute to climate change, I know that the science behind the endangerment finding hasn’t changed. If anything, the evidence has grown that greenhouse gas emissions are warming the planet and threatening people’s health and safety. Heat waves, flooding, sea-level rise and wildfires have only worsened in the decade and a half since the EPA’s ruling.

Regulations over the years have cut emissions from power generation, leaving transportation as the largest source of greenhouse gas emissions in the U.S.

The scientific community agrees that vehicle emissions are harmful and should be regulated. The public also agrees, and has indicated strong preferences for cars that pollute less, including both more efficient gas-burning vehicles and electric-powered ones. Consumers have also been drawn to electric vehicles thanks to other benefits such as performance, operation cost and innovative technologies.

That is why I believe the EPA’s move will not stop the public and commercial transition to electric vehicles, but it will make that shift harder, slower and more expensive for everyone.

Putting carmakers in a bind

The most recent EPA rule about vehicle emissions was finalized in 2024. It set emissions limits that can realistically only be met by a large-scale shift to electric vehicles.

Over the past decade and a half, automakers have been building up their capability to produce electric vehicles to meet these fleet requirements, and a combination of regulations such as California’s zero-emission-vehicle requirements have worked together to ensure customers can get their hands on EVs. The zero-emission-vehicle rules require automakers to produce EVs for the California market, which in turn make it easier for the companies to meet their efficiency and emissions targets from the federal government. These collectively pressure automakers to provide a steady supply of electric vehicles to consumers.

The new EPA move would undo the 2024 EPA vehicle-emissions rule and other federal regulations that also limit emissions from vehicles, such as the heavy-duty vehicle emissions rule.

The possibility of a regulatory reversal puts automakers into a state of uncertainty. Legal challenges to the EPA’s shift are all but guaranteed, and the court process could take years.

For companies making decade-long investment decisions, regulatory stability matters more than short-term politics. Disrupting that stability undermines business planning, erodes investor confidence and sends conflicting signals to consumers and suppliers alike.

A slower roll

The Trump administration has taken other steps to make electric vehicles less attractive to carmakers and consumers.

The White House has already suspended key provisions of the Inflation Reduction Act that provided tax credits for purchasing EVs and halted a US$5 billion investment in a nationwide network of charging stations. And Congress has retracted the federal waiver that allowed California to set its own, stricter emissions limits. In combination, these policies make it hard to buy and drive electric vehicles: Fewer, or no, financial incentives for consumers make the purchases more expensive, and fewer charging stations make travel planning more challenging.

Overturning the EPA’s 2009 endangerment finding would remove the legal basis for regulating climate pollution from vehicles altogether.

But U.S. consumer interest in electric vehicles has been growing, and automakers have already made massive investments to produce electric vehicles and their associated components in the U.S. – such as Hyundai’s EV factory in Georgia and Volkswagen’s Battery Engineering Lab in Tennessee.

Global markets, especially in Europe and China, are also moving decisively toward electrifying large proportions of the vehicles on the road. This move is helped in no small part due to aggressive regulation by their respective governments. The results speak for themselves: Sales of EVs in both the European Union and China have been growing rapidly.

But the pace of change matters. A slower rollout of clean vehicles means more cumulative emissions, more climate damage and more harm to public health.

The EPA’s move seeks to slow the shift to electric vehicles, removing incentives and raising costs – even though the market has shown that cleaner vehicles are viable, the public has shown interest, and the science has never been clearer. But even such a major policy change can’t stop the momentum of those trends.
