Why ‘Waiting Until It Breaks’ Can Be an Expensive HVAC Strategy
For many homeowners, heating and cooling systems fall into the “out of sight, out of mind” category. However, even if the air is flowing and the temperature feels right, taking an “if it’s still running, it’s still fine” approach to your HVAC system today can lead to higher repair bills, rising energy costs, uncomfortable downtime and rushed replacement decisions tomorrow.

(Feature Impact) For many homeowners, heating and cooling systems fall into the “out of sight, out of mind” category. However, even if the air is flowing and the temperature feels right, taking an “if it’s still running, it’s still fine” approach to your HVAC system today can lead to higher repair bills, rising energy costs, uncomfortable downtime and rushed replacement decisions tomorrow.
While it may seem cost-effective in the short-term, the experts at Mitsubishi Electric Trane HVAC US (METUS) suggest proactive maintenance and planned upgrades as the smarter financial move in many cases.
The Hidden Costs of Waiting
HVAC systems rarely fail without warning. Instead, they decline gradually, becoming less efficient and more prone to breakdowns over time. They commonly fail during extreme summer heat or winter cold when demand is highest. A broken air conditioner during the peak of summer doesn’t just create discomfort; it often comes with longer service wait times and higher emergency repair costs, while also leaving you with less time to compare equipment options, take advantage of rebates or make a convenient installation appointment.
Small issues – like a dirty filter restricting airflow or worn components adding stress to other parts of the system – can also snowball into bigger, more expensive repairs. Similarly, inefficient systems, especially older or poorly maintained ones, can drive up monthly energy costs, using more energy and putting additional stress on the components to maintain the same comfort level.
Signs Your HVAC System Needs Attention
Even if your HVAC system hasn’t broken down, it may already be showing signs of trouble. Consider these warning signs that your HVAC system may be due for replacement:
- Rooms heating and cooling unevenly
- Rising utility bills with no clear cause
- Strange noises or unusual odors
- Weak airflow or reduced comfort
- Frequent service calls
- System age approaching 10-15 years or older
The Value of Preventive Maintenance
Routine maintenance can help catch small issues early before they become costly repairs while extending system lifespan and maintaining performance. Regularly replacing or cleaning filters helps maintain airflow and efficiency while keeping vents clear and outdoor units free of debris ensures your system can operate at its best. Professional seasonal tune-ups can also help catch small issues early and extend the lifespan of your equipment.
How Planning Ahead Can Pay Off
Replacing an aging HVAC system before it fails gives homeowners an invaluable asset: time. Instead of making a rushed decision in extreme temperatures, you can make thoughtful decisions based on comfort goals, budget and home needs. It also allows for evaluating newer technologies that can improve everyday comfort and lower operating costs. Today’s systems offer features that weren’t available a decade ago, allowing for customization of indoor environments that was once out of reach.
Benefits of Modern HVAC Upgrades
Upgrading your system isn’t just about avoiding breakdowns – it’s about enhancing your everyday comfort and improving efficiency and control. Modern HVAC solutions, like Zoned Comfort Solutions from Mitsubishi Electric, allow for personalized temperatures in different rooms or areas of the home. Using energy-efficient heat pump technology, they provide heating and cooling in one efficient system for better temperature consistency and control in every season.
Newer systems – both ducted and ductless – tend to run more quietly and offer flexible installation. They can be used with existing ductwork or installed in homes without it, making them a strong option for room additions, garages, sunrooms or spaces that are traditionally difficult to heat or cool.
Long-Term Benefits of Upgrading
When you shift to proactive HVAC maintenance, the benefits can add up and you can gain confidence your home is prepared, regardless of what the seasons have to offer. Upgrading your system ahead of a total failure reduces the risk of unexpected breakdowns, lowers energy costs and provides more consistent comfort throughout the year. There’s also the added bonus of increasing your home’s appeal and value for future buyers.
While waiting until it breaks might feel like the easy choice, it may also be the most expensive one. Visit mitsubishicomfort.com to explore your options and learn more.

Heat waves can leave homes dangerously hot – even for young, healthy adults
Heat waves can turn homes into dangerous heat traps—especially during blackouts or in houses without AC—pushing indoor temperatures and humidity into lethal territory even for young, healthy adults, not just the elderly.
Heat waves can leave homes dangerously hot – even for young, healthy adults
Zoltan Nagy, Eindhoven University of Technology
Most people know that heat waves can be dangerous, but what they may not realize is that the heat indoors can be much worse than outdoors.
When the power goes out and air conditioning stops, or in homes without cooling, a house starts to function like a greenhouse during a heat wave. Heat enters through windows and walls and has nowhere to go. Air stagnates.
Within hours, indoor temperatures can climb well above what the thermometer shows outside, especially on upper floors and in rooms with south-facing windows. Over longer periods, especially if temperatures don’t cool off overnight, conditions can become lethal.
Most heat-related deaths occur indoors. When a heat dome sent temperatures soaring in the Pacific Northwest in 2021, 98% of the more than 600 deaths in British Columbia happened inside homes. Washington and Oregon also saw high numbers of deaths in homes that lacked air conditioning.
In Europe, where only 1 in 10 households have air conditioning, heat waves killed an estimated 60,000 people in 2022 and 47,000 in 2023, largely inside buildings never designed for these temperatures.
People of all ages are at risk in heat waves like these. I spent eight years at the University of Texas at Austin studying how buildings respond to extreme heat. In a recent study, my team assessed the heat risk in every single-family home in Austin.
We found that even younger, healthy adults face far more risk than they realize.
How hot is too hot for a human body?
Your body maintains a core temperature of about 98.6 degrees Fahrenheit (37 degrees Celsius). To cool down, it pushes blood to the skin and sweats. But when air temperature is high, that convective cooling weakens. When humidity is also high, sweat cannot evaporate.
If the body has no way to release heat, core temperature rises. If the core temperature increases past about 104 F (40 C), the body’s thermoregulation starts to fail. Past 109 F (42.8 C), death becomes likely.
What makes indoor heat especially dangerous is that it does not let up at night in homes that lack air conditioning. Outdoor temperatures typically drop after sunset, and someone outside can get a few hours of recovery. But a poorly insulated home that has been absorbing heat all day releases that heat slowly, keeping indoor temperatures elevated through the night. A person inside the home never gets a break.
After two or three nights of this, even healthy people start to be at serious risk for heat-related illnesses.
Why homes heat up more than people expect
People tend to underestimate indoor heat for a few reasons.
One is that the thermostat typically sits on one wall in one room. It does not tell what the temperature is in an upstairs bedroom or near a sun-facing window. In older, underinsulated homes, the actual felt temperature can exceed 90 F (32.2 C) even when a thermostat reads 75 F (23.9 C). The hot walls, ceilings and windows can radiate heat directly onto your body.
Another reason is that people assume all homes respond to heat the same way. However, a newer home with double-pane windows and good insulation acts like a thermos, keeping heat out for a longer time. An older home with single-pane windows and cracks in the walls heats up fast.
Two houses on the same street, exposed to the same outdoor conditions, can have completely different temperatures inside. And in a blackout, where neither home has cooling, those differences can become a matter of life and death.
What we found in Austin
Our study combined two datasets. From Austin’s tax appraisal records, we pulled basic property information, such as the year the home was built, the size and the number of stories for each of the city’s 213,000 single-family homes. We then matched each home to the most similar energy simulation models in a U.S. Department of Energy database that contains thousands of detailed, physics-based building energy models representing the U.S. residential building stock.
Using those models, we simulated each building’s indoor temperatures over time during a three-day heat wave and power outage with outdoor temperatures above 110 F (43 C).
We found that 85% of homes got hot enough to pose a significant risk of death for an elderly occupant. But what surprised us was the risk to younger people.
Under today’s climate conditions in Austin, about 15% of homes already have the potential to get hot enough without air conditioning to pose serious heat risks to healthy adults. Under future warming scenarios, that number jumps to as high as 65% if average summer highs reach 104 F (40 C). Further, climate projections for Austin show that heat waves will double in frequency by the end of the century.
We found three types of buildings and accompanying risks:
- Resilient homes, which are newer and well insulated, tended to have temperature and humidity conditions that would be survivable for an elderly occupant throughout the simulated heat wave with blackout.
- Critical-risk buildings, which are mostly older homes, became dangerous almost immediately.
- And then there was the middle group – homes where temperatures rose slowly during the simulated blackout, day by day, possibly giving occupants a false sense of security until it was too late.
Texas has already seen conditions like our case study’s – a heat wave paired with a power outage. In 2024, a derecho knocked out power for nearly 900,000 Houston households while the heat index climbed to 100 F (37.8 C). Seven weeks later, Hurricane Beryl cut power to 2.6 million homes, leaving them without power for over three days, with temperatures over 90 F (32.2 C).
What you can do to stay safe
If you can’t get cooling at home, there are steps you can take that can help.
Move to the lowest floor of your home, where it will be coolest. Close the blinds and curtains on sun-facing windows. Drink water constantly to stay hydrated, which is essential for regulating body temperature.
If you’re facing a blackout, be sure to also check on elderly neighbors, especially those living alone. You can also try to find a public cooling center; many cities now open them during heat emergencies.
Longer term, upgrades such as reflective window film, attic insulation and lighter-colored roofing can reduce how much a home heats up. After the 2021 heat dome, British Columbia’s coroner recommended updating building codes to address heat.
Our own findings point in the same direction: We propose that new homes should be required by building codes to maintain conditions in which at least light physical activity remains possible for all occupants for at least 72 hours during a power outage.
As summers get hotter with climate change and blackouts become more frequent, the risks of people suffering heat illnesses will only continue to rise.

(Feature Impact) Relationships and plumbing have something in common: they can both benefit from practicing smarter bathroom habits. Whether you’re sharing a household with your family, a partner or roommates, good etiquette in these frequently shared spaces can save everyone’s sanity – just like rethinking your flushing routines can save your pipes.
From simple annoyances like leaving the toilet seat up to potentially costly mistakes like clogging your plumbing by flushing the wrong items, a new survey from the Responsible Flushing Alliance (RFA) illuminated a variety of bad habits that cause the most tension in American homes.
In addition to shedding light on these problems, the alliance outlined solutions you can implement at home to restore peace in your restroom. Plus, you can gamify the habit changes to make them more entertaining.
“Our goal is to revolutionize public education by keeping it highly engaging, memorable and fun,” RFA President Lara Wyss said. “We are challenging the public to rethink their everyday habits.”
Get started with these seven tips:
Replace the toilet roll properly
Don’t be the reason someone gets stranded with nothing but a cardboard tube in their moment of need. Keep extra rolls nearby, and when you’re down to the last square of toilet paper, make it a race against the clock to replace it.
Use the (flush) force
An unflushed toilet was listed as the biggest bathroom pet peeve by 37% of survey respondents. To make it fun for the family, introduce a new tradition: before you leave the bathroom, pretend there’s an invisible force field pushing you back to make sure you’ve flushed and are good to go.
Hunt for sink and shower hair
Leaving hair in the drain isn’t just a source of potential plumbing clogs – it’s also an irritant for 35% of respondents. After you shower or style your hair, make it a game to see how many stray strands you can capture and deliver to the trash can.
Clean it and close it
You’ve probably heard jokes about people who leave the toilet seat up, so don’t make yourself the punchline. For a completely un-mockable routine, grab the brush to give the bowl a quick swish after you flush, ensure the seat is down and use an anti-bacterial wipe to leave everything sparkling. You’ll notice cleaning wipes bear the Do Not Flush symbol, which means they go in the trash and never the toilet.
Conquer the counter
Toothpaste and water often splatter all over the place, so to be a polite bathroom roommate, wipe up the mess before it’s even had a chance to dry. Keep cleaning wipes or rags within easy reach and give yourself a 10-second deadline to leave surfaces spotless.
Practice good towel etiquette
Wet towels don’t belong on bathroom floors. If they still have a use or two left in them, banish them back to your towel rack. Otherwise, challenge yourself to a game of laundry basketball, aiming for the hamper.
Don’t flush the un-flushable
According to an RFA survey, half of Americans are still flushing things they know they shouldn’t, like paper towels, feminine hygiene products and non-flushable wipes. Since clearing a clog in your home can cost anywhere from $300-$15,000 or more, the only thing you’ll be draining with habits like these is your wallet.
“Always check wet wipes for the Do Not Flushsymbol and disposal instructions, which helps us protect not only the health of our homes and environment but our relationships, too,” Wyss said.
