Summer heat is often a welcome reprieve from the winter chill. An icy, cold world has given way to greenery and sunshine — it is almost as if life has returned to the world. Especially if you live in a climate with extreme winters, the warmer weather of summer can be an exciting time. Unfortunately, those balmy summer days can be just as dangerous to your health as being trapped out in the cold. As people make their way outside to sunbathe, visit the park, take a stroll, or participate in a number of summer activities, it is important to be aware of the risks that summer heat can pose to your health. Even the healthiest people are susceptible to adverse effects from summer heat, but certain demographic groups are at an even higher risk.


Anymore, saving energy is an essential part of our day-to-day lives. With the threat of climate change becoming more real every day, most folks are constantly looking for ways to save more energy. While factories and industrial firms are never a great example of healthy energy practices they do have most of us beat in one specific sector: heat exchangers. Factory bosses have been installing heat exchangers to salvage the heat from waste gases and thus, the heat energy as well. Factories are hardly the model for this though, engines, ships and planes all effectively use similar heat exchange components to accomplish various efficiency goals. So what is a heat exchanger and how can the average, everyday person use it to their benefit in their quest for better energy efficiency? Let’s take a look.


The polar vortex was all over the news just a couple of weeks ago. It broke negative-degree records all over the United States and redefined our local idea of cold. For example, the Twin Cities hit an all-time low of -32F, the lowest since 1996, and some states even recorded temperatures as low as the South Pole. This put an emphasis on the importance of having a reliable heater. So as folks started pushing their heating bills up in Sioux Falls as wind chills dropped the temperature to -55 degrees Fahrenheit, everyone started thinking about just how long their heater will last and what other things they could use to beat back the persistent winter chill. We’ve collected some of the most “creative” ways people are staying warm this winter, which really make a new furnace and heat exchange system look awfully appealing.


A damaged heat exchanger is a cause for concern for many reasons. Initially, the heating in the home might falter, resulting in a chilly home. Next is a sometimes expensive repair bill. But if left unchecked, a broken or damaged heat exchanger can result in far more serious damages. The release of carbon monoxide is a very real concern with damaged heat exchangers. Today, the Heat Exchange Experts will outline the signs of carbon monoxide poisoning.


When it comes to replacing your heater, most people’s enthusiasm could be described as tepid to say the least. It’s an idea that we all have to warm up to. This is likely because we don’t have to replace the furnaces and heaters in our homes all that often. In fact, if you recently moved into a new home, or if you’ve been in a home for a long time, you might not know when a heater was last replaced. Fortunately, the Heat Exchanger Experts are here to help you identify when it’s time to upgrade the heater in your home.


When the weather begins to cool, our first instinct is to reach toward the thermostat and turn on the furnace. We rely on our furnaces to keep our homes warm and liveable during even the coldest months. But what if you power on your furnace, and instead of warm air, you get nothing at all? Your heat exchanger is one of the hardest working parts of your HVAC system, and as such, it is prone to its share of problems. The Heat Exchanger Experts have seen everything there is to see when it comes to problematic heat exchangers. In today’s blog, we’ll outline some of the common problems that homes face when the first turn on their heaters for the winter seasons.


There’s a common line of thought that postulates that “bigger is better.” While this may be true for bags of popcorn at a movie theater, or even bowls of ice cream on a hot sunny day, this is less true for the size of furnace for your home. Instead, when it comes to finding the right size heater for your home, you’ll want to follow the Goldilocks test, and find a unit that is “just right.” Today, the Heat Exchanger Experts will discuss the importance of finding the right size furnace for your home.


The Heat Exchange Experts have made a name for themselves as the leaders in heat exchanger repairs and training seminars. But what sets our classes apart from our competitors? It’s our commitment to providing you with hands-on learning opportunities. We feel that one of the most effective ways to learn more about these complicated machines is to see their points of failure and identify the signs of disrepair. In today’s blog, we’ll discuss why hands-on learning is beneficial for students who take our seminars.


Here we are in mid-February, and winter weather has settled in across the whole country. Your clients are snuggled up at home, under quilts and blankets, and basking in the warm comfort that their furnace provides them. And while they may not know it, a heat exchanger makes up a critical component of their heated comfort. If that heat exchanger is damaged, they may be at risk for a variety of hazards that could affect their standard of living, and their health.

Heat Exchange Experts, Inc. has been teaching furnace repair training courses for years, so we compiled this guide to the dangers a damaged heat exchanger can pose, so you can better inform your clients.

One of the leading causes of accidental death within the home can be traced back to furnace installation and maintenance. This doesn’t occur in a dramatic or flashy way, there will be no explosion, smoke, or any immediately noticeable sign that anything is wrong. In fact, the culprit is odorless, tasteless, and completely invisible. It comes in the form of CO, or carbon monoxide, which is incredibly lethal in even moderate doses. The culprit for many of these deaths is a faulty or cracked heat exchanger, which allows the deadly gas to quickly fill a home.

Heat exchanger inspection, training, and repair are crucial
