May 17, 2022

Boilers have been around since the late 1800s, and boiler technology has changed a lot since then. What once used coal and wood to produce power and heat now uses oil and natural gas, operating at much greater efficiency.

 

Newer boilers add much more to a home than they did 150 years ago. Unfortunately, not many people know anything about boilers beyond those systems of the old days. In light of that knowledge deficit, we will dispel some myths and share some intriguing boiler facts to keep you up to date.

Common Myths About Boilers

Many myths about boilers go back decades, when boiler manufacturers didn’t have the standards they do today. Older boilers were unreliable, inefficient, and didn’t use sustainable methods in their manufacturing or day-to-day operation. Modern boilers are unrecognizable compared to those old boilers.

 


Myth #1 | Boilers Are Expensive

Many people think boilers are too expensive for their homes. While they are costly to install, they are very cheap in the long run. Because of how newer boilers operate, they are much more affordable than older boilers.

 


Myth #2 | Boilers Are Inefficient

Manufacturers did not insulate older boilers well, and much of the heat produced by them dissipated due to these poor system flaws. Newer boilers do not have this problem.

 

One of the lesser-known boiler facts is that a modern boiler is 95% efficient. That means they use 95% of their fuel in heat production, compared to the 50%-60% efficiency of older boilers.

 


Myth #3 | Boilers Are Unreliable

This myth arises from many problems already addressed. The inefficiency of older boilers made them poor heaters for the home, and they were constantly breaking down due to poor manufacturing. Some even say that the new technology is not old enough to trust.

 

The truth is that boilers have come a long way. The technology has improved exponentially in the last 20 years because manufacturers and service technicians addressed problems as they arose. Now, boilers are as reliable as any other heater, if not more.

 

Most of the reliability of a machine comes from how well you take care of it. It is best to service any heaters or air conditioners at least once a year to check for any issues. Such services will catch most problems before they arise.

 


Myth #4 | Boilers Make Indoor Air Humid

Many people believe that boilers make the air inside of your home more humid than other forms of heating. This myth is simply untrue. A boiler is a completely enclosed system. All the water in the system stays within the system. No moisture should escape the lines. Boilers add heat to the air, not steam. A properly running boiler will produce heat as dry as any other heating system.

 

If water is leaking out of your boiler system and making the air humid or simply dripping out of the lines, call Professional Services for a repair immediately. The system needs serious attention.

 


Boiler Facts

Only about 6% of homes in the United States have a boiler. Because boilers are rare in homes, few people know much about them. With that in mind, here are some facts about boilers that will help you understand their characteristics.

 


Boilers Don’t Always Boil Water

Some boilers, known as steam boilers, do boil water, but most modern boilers installed in a home don’t actually boil the water in the system. These boilers are much more efficient.

 

The lower the temperature of the water, the more efficient the system. Water heated to about 60 or 70 degrees is all a boiler requires to heat your home. This lower temperature will provide a comfortable atmosphere inside your home and lower your power bill substantially.

 


Boilers Need High Water Pressure

Your boiler won’t function properly if the water pressure isn’t high enough. The water must be at least 15 PSI for your boiler to perform at peak ability. If your boiler isn’t running as efficiently as you would like, check to ensure your water pressure is high enough.

 

Low water pressure is a relatively easy fix compared to buying a new boiler. Check to see whether that’s the problem before considering a new boiler.

 


New Boilers Are Cheaper To Operate

The efficiency of newer boiler systems makes them a great way to save money. Because they are so much better at using fuel, the cost to run them is much lower. Consider upgrading to a newer system if your older boiler costs you too much money to run. The cost over time will lower dramatically.

 


Boilers Operate Using Simple Physics

Boilers use the properties of water to help with their efficiency. The flame heats the water, and hot water rises to the top of the tank. The heated water flows through the lines in your house, heating your home. The cold water returns, falling to the bottom of the tank, where it is heated and pushed back through the pipes.

 

The water moves continuously, heating your home until the boiler turns off or reaches the desired temperature.

 


Boilers in Your Home

Hopefully, discussing common myths about boilers and boiler facts has helped paint a clearer picture of how they operate and their benefits. If you are building a new home, consider installing a boiler system. It will heat your home better than a forced-air system while operating at a much lower price. If your old boiler gives you problems or routinely costs you money, upgrading to a new boiler is more efficient and will dramatically lower your power bill.

 

Your boiler should be serviced and maintained once a year, preferably in the fall before cold temperatures hit. You can learn more about boiler system maintenance here.

Furnace Won't Turn On in Cedarburg, WI? A Step-by-Step Troubleshooting Guide

September 30, 2026
If your furnace won't turn on in Cedarburg, WI, there are a few common culprits worth understanding before calling in a professional. In our service calls throughout Cedarburg, from homes near the historic Cedar Creek Settlement to properties further out toward Highway 60, our team sees the same handful of issues come up again and again once temperatures start to drop. A quick check of the thermostat settings is a good starting point, along with a look at the power supply and any tripped circuit breakers, but a proper diagnosis is best left to a trained technician through furnace repair service . The air filter is worth a look too, and if there are any strange noises or scents, those call for professional attention right away. Keep reading to learn more about diagnosing and addressing furnace issues safely. Common Causes for a Furnace Not Turning On When a furnace won't turn on, it can be frustrating, especially during the coldest months of a Wisconsin winter. One common cause is a tripped circuit breaker. If the furnace isn't getting power, the electrical panel is the first place worth checking. Another possibility is a clogged air filter, which can restrict airflow and cause the furnace to shut down as a safety measure. Regular maintenance goes a long way toward avoiding this issue altogether. The pilot light is also worth considering. If it's out, the furnace won't ignite at all. A malfunctioning thermostat could be at fault as well, so confirming it's set correctly and functioning properly is an easy first check. By identifying these common causes, homeowners can get a clearer sense of what might be going on before a technician arrives. Working in homes across Cedarburg, our team at Professional Services Heating, AC & Electric Repair is here to guarantee comfort and warmth whenever these issues pop up. Check Your Thermostat Settings Has the thermostat been double-checked? Sometimes it really is the simplest things that trip people up. Making certain the thermostat is set to "heat" rather than "cool" is worth confirming first, especially during shifting seasons when settings can get overlooked. The temperature setting matters too. If it isn't set higher than the current room temperature, it won't signal the furnace to kick on. Checking whether the thermostat is in "auto" mode is worth a look as well, since a setting of "manual" or "off" will keep the furnace from activating. For homes with a programmable thermostat, confirming the schedule hasn't been accidentally changed is a good next step. Replacing the batteries is worth trying too if it's a battery-operated unit, since a weak battery can prevent proper function. If these checks don't resolve the issue, it may be worth having a professional evaluate whether the system needs repair or whether furnace replacement makes more sense for long-term efficiency. Inspecting Your Power Supply and Circuit Breaker Before digging deeper into furnace issues, checking the power supply and circuit breaker is a smart next step, since these are often the root of the problem. Confirming the furnace is properly connected to power comes first. For a gas furnace, the gas valve should also be checked to confirm it's open. From there, the circuit breaker panel is worth a look. Tripped breakers can easily disrupt power to a furnace, and flipping one back on may resolve the issue temporarily. If it trips again, that's a sign of an underlying issue that needs professional attention rather than repeated resets. Fuses related to the furnace are worth checking too, since a blown fuse can cut off power entirely. Based on what we see in Cedarburg homes, checking these basics rules out simple issues before moving on to more complex furnace diagnostics, and regular heating system maintenance helps prevent these problems from recurring season after season. Step-by-Step Guide to Diagnose Your Furnace Problems Diagnosing furnace problems can feel overwhelming, but breaking it down step by step makes it more manageable. Thermostat Settings: Confirm the thermostat is set to "Heat" and the temperature is higher than the current room temperature. Air Filter: A dirty air filter can restrict airflow and cause overheating, so it's worth inspecting and replacing if needed. Safety Switches: Check for any safety switches that may have tripped, especially near the furnace door, and reset them if needed. Regular Maintenance: An annual furnace tune-up is essential for a system's longevity and helps everything run smoothly through the season. Once these steps are checked, homeowners will have a better sense of what's going on. If nothing changes, it's time to bring in further professional assistance. Signs You Need Professional HVAC Help Recognizing when it's time to call in the experts matters just as much as basic troubleshooting. Strange noises like banging or rattling are often a red flag that something's amiss inside the system. A furnace that frequently cycles on and off can indicate a more serious issue too. If adjusting the thermostat produces little change in temperature, or if there's an unusual smell, especially gas, professional help should be sought out immediately rather than waiting. Unexpected spikes in energy bills can also mean a system is struggling to operate efficiently, and a complete breakdown shouldn't be left unaddressed for long, particularly during a Cedarburg winter. Professional Services Heating, AC & Electric Repair is here to provide 24/7 emergency assistance and expert solutions, keeping comfort and safety a top priority for every household we serve. Getting Your Furnace Back on Track This Winter A furnace may not always be the reliable hero it's expected to be during winter's chill, and that's exactly why a proper troubleshooting process matters. If these steps haven't resolved the issue, don't hesitate to call in the professionals rather than continuing to troubleshoot alone. Keeping a Cedarburg home cozy and warm all season starts with knowing when to bring in the right expertise.

Why Is My Furnace Overheating in Port Washington, WI? Causes and What to Do

September 30, 2026
If your furnace is overheating in Port Washington, WI, you're likely facing issues like dirty air filters or blocked vents. In our service calls throughout Port Washington, from homes near the harbor to properties further inland along Highway 33, these problems make the furnace work harder and heat up excessively, especially once the coldest stretches of winter set in. You might notice unusual noises, strange smells, or an overly warm home, and it's vital to turn off the furnace and have a professional check settings, filters, and vents through a proper furnace repair visit. If problems persist, there's more worth understanding to keep your system running safely and efficiently. Common Causes of Furnace Overheating When it comes to furnace overheating, several common issues tend to lead to this frustrating problem. One of the primary culprits is a dirty air filter. When filters clog, airflow gets restricted, causing the furnace to work harder and overheat. Blocked vents are another issue. If furniture or debris obstructs airflow, it can create hot spots throughout the home and lead to overheating. A malfunctioning thermostat can also send incorrect signals to the furnace, causing it to run longer than necessary. Blower motor issues are common too. If it's malfunctioning, warm air can't circulate properly through the home. Lack of regular maintenance can lead to a buildup of dust and debris that strains the system over time. Working in homes across Port Washington, our team has found that regular furnace maintenance is essential to prevent overheating and keep a system running efficiently for years. Recognize the Signs of an Overheating Furnace How can you tell if a furnace is overheating? There are several key signs worth watching for. Unusual noises, like banging or screeching, could indicate stress building up inside the system. A burning smell is a red flag too. It might mean there's dust buildup or even overheating parts that need attention. If a home feels too hot or unevenly heated, that's a sign something's off with airflow or thermostat calibration. The furnace itself is worth checking too, since excessive heat on its exterior can indicate a serious problem developing. Finally, a furnace that frequently shuts off or cycles on and off quickly deserves attention right away. Based on what we see in Port Washington properties, recognizing these signs early helps homeowners take action before more significant issues arise, keeping a furnace operating safely through every cold snap. What Happens During a Professional Overheating Diagnosis When a furnace starts overheating, a professional evaluation is the safest path forward rather than attempting repairs at home. A technician will start by confirming the furnace is powered down to prevent further stress on the system. Thermostat settings get checked next, since a setting that's too high can cause the unit to work overtime unnecessarily. Air filters are inspected closely too, since dirty filters restrict airflow and are one of the most common causes we see during furnace maintenance visits throughout Port Washington. Vents and registers get checked to confirm they're unobstructed, allowing for proper air circulation throughout the home. A thorough listen for unusual noises and a check for visible wear or damage rounds out a complete diagnostic visit, giving homeowners a clear picture of whether repair or replacement makes more sense based on the age and condition of the unit. When to Seek Professional Help for Furnace Overheating Could there be signs pointing toward the need for professional help that are easy to overlook? A furnace that frequently shuts off unexpectedly or makes strange noises is a clear red flag. An unusual smell is worth paying attention to as well, since that can signal a serious issue needing urgent attention. If basic checks like the air filter or thermostat settings haven't resolved the problem, it's time to bring in a professional rather than continuing to troubleshoot alone. A spike in energy bills without an apparent reason can also point to inefficiencies or malfunctions that need expert diagnosis. Regular heating system service helps prevent these issues from escalating into bigger, more costly repairs. How to Prevent Furnace Overheating in the Future Taking proactive steps can help prevent future furnace overheating well before it becomes a problem. Committing to regular maintenance matters most. Scheduling annual inspections helps catch potential issues before they escalate into something more serious. Air filters should be replaced every one to three months as well, since dirty filters restrict airflow and make a furnace work harder than it should. Keeping vents clear of obstructions like furniture or curtains helps guarantee proper airflow throughout the home. Upgrading to a programmable thermostat is worth considering too, since it helps maintain ideal temperature settings without overworking the system. For furnaces showing signs of age, exploring replacement options is worth a conversation with a professional. A new, energy-efficient model can greatly reduce overheating risks and enhance comfort throughout the home. Keeping Your Port Washington Home Safe and Warm As winter wraps Port Washington in its icy embrace, a furnace becomes a real lifeline against the cold. Understanding the reasons behind overheating helps safeguard that comfort for the whole season. Just as a flickering flame needs tending, a heating system needs proactive care too.
