What are some of the most common signs of a water heater issue?
River City Heating & Air • November 25, 2025
A reliable water heater is something most homeowners don’t think about until it stops doing its job. Whether you have a traditional tank system or a tankless unit, water heater problems often worsen over time. Recognizing early warning signs can help you avoid cold showers, water damage, and more expensive repairs. At River City Heating & Air, we provide expert water heater repair and replacement in the greater Bismarck area. Here’s a look at five common signs of water heater trouble.
Unusual Noises Coming from the Tank
If you hear popping, rumbling, or banging sounds coming from your water heater, it’s often a sign that sediment has built up inside the tank. Over time, minerals settle and harden on the bottom, trapping water beneath the sediment. As the water bubbles up, it creates loud noises. This noise is your early warning—don’t ignore it.
Fluctuating or Insufficient Hot Water
One of the most obvious signs of a problem is inconsistent water temperature. If your water suddenly goes cold, doesn’t get as hot as it used to, or fluctuates during use, it could indicate a failing heating element or a malfunctioning thermostat. Tankless systems may show similar symptoms if the burner is failing. Any change in performance is worth investigating before the issue becomes more severe.
Discolored or Rusty Water
If you turn on the hot water tap and notice the water looks brown, orange, or rusty, your water heater may be corroding from the inside. This commonly means the anode rod has worn out and can no longer protect the tank from rust. Left unchecked, corrosion can eat through the metal and lead to leaks or complete tank failure.
Leaks Around the Water Heater
Even minor pooling around your water heater should never be ignored. Leaks can come from loose connections, a failing valve, or cracks in the tank. Once a tank begins to crack, replacement is usually necessary. Water leaks can quickly cause structural damage and mold growth, so prompt action is crucial.
Age and Slow Performance Decline
Conventional water heaters commonly last between eight and twelve years. As they age, they naturally become less efficient and more prone to problems. If your system is approaching or past this range and you notice slower heating, unusual behavior, or rising energy costs, it may be nearing the end of its useful life. Replacing it before it completely fails could save you money in the long run.

When winter sets in, many homeowners dread the spike in their heating bills. As temperatures drop, your heating system has to work harder to keep your home comfortable—especially if it’s not running efficiently. Fortunately, there are several simple and effective ways to reduce energy use without sacrificing warmth. By combining smart habits with a bit of professional maintenance, you can stay cozy all season long while keeping your energy costs under control. At River City Heating & Air, we provide heating system maintenance that helps to keep your system operating at optimal efficiency. Here are four tips for lowering your home’s heating expenses this winter. Seal Air Leaks Around Windows and Doors Even the most efficient furnace can’t keep up if warm air is constantly escaping through gaps and cracks. Inspect your home for drafts, especially around windows and doors. Sealing leaks with weatherstripping or caulk is a quick and affordable fix that can make a noticeable difference in comfort and heating costs. For larger gaps or older homes, consider having a professional energy audit performed to identify and seal hidden sources of air loss. Improve Insulation Poor insulation is one of the biggest reasons for high heating bills. If your attic, basement, or walls are under-insulated, much of your home’s heat could be escaping. Adding insulation helps your home retain warmth longer, allowing your heating system to cycle less frequently. Insulation improvements can be a one-time investment that pays off year after year in the form of lower energy bills and increased comfort. Use a Programmable Thermostat A programmable or smart thermostat helps you optimize your heating schedule based on your lifestyle. Lowering the temperature while you’re asleep or away from home can lead to significant energy savings. Keeping your thermostat just a few degrees lower can often reduce heating costs without making your home feel chilly. Get Professional HVAC Maintenance One of the most effective ways to cut heating costs is to schedule professional HVAC maintenance before the coldest weather arrives. A trained technician can inspect your system, check for worn parts, and make sure everything is running at peak efficiency. Even small issues can force your system to work harder than necessary, leading to higher energy bills. Routine maintenance not only improves efficiency, but can also extend the lifespan of your heating equipment and prevent breakdowns in the middle of winter.

When the weather turns cold, your furnace becomes one of the most important systems in your home. A reliable furnace not only keeps your family comfortable, but also helps protect your home from the risks of freezing temperatures. However, like any mechanical system, furnaces can develop problems over time. Being able to recognize early warning signs of trouble can help you address issues before they cause breakdowns. At River City Heating & Air, we provide expert furnace repair in the greater Bismarck area. Here are four warning signs that your furnace needs professional attention. Unusual Noises During Operation Your furnace may normally produce a low, consistent sound when running, but loud or strange noises are often signs of a problem. Banging, squealing, or rattling can point to loose components, worn belts, or ignition issues. Ignoring these sounds could lead to further issues inside the system. Paying attention to unusual noises allows you to catch problems early and schedule repairs before they grow worse. Uneven Heating Throughout the Home If you notice that some rooms feel warm while others stay chilly, it could mean your furnace isn’t distributing heat properly. Uneven heating can be caused by clogged filters, ductwork issues, or a struggling blower motor. Not only does this make your home less comfortable, but it also forces your furnace to work harder, leading to higher energy bills. A technician can diagnose the cause and restore even heating throughout your house. Short Cycling or Constant Running If your furnace turns on and off frequently, it may be short cycling. This can result from issues such as a dirty air filter, malfunctioning thermostat, or problems with the heat exchanger. On the other hand, if the furnace seems to run constantly without adequately heating the home, that’s also a red flag. Both issues indicate inefficiency that needs prompt attention. Strange or Burning Smells Ongoing and strange odors from your furnace should not be ignored. A burning smell could point to electrical issues or overheating parts, while a musty odor might mean mold growth in the ductwork. Any unusual smell warrants an inspection, as it could indicate a safety hazard in addition to mechanical trouble.

As the cooler months approach, many homeowners are preparing to turn their heating systems back on after a long summer of inactivity. While it may be tempting to simply flip the switch and hope for the best, scheduling a professional inspection before the cold weather arrives is one of the smartest steps you can take. A thorough inspection ensures your heating system is safe, reliable, and ready to keep your family comfortable all season long. At River City Heating & Air, we provide expert HVAC maintenance in the greater Bismarck, ND area. Here are four important reasons to schedule a professional heating inspection this fall. Prevent Breakdowns Few things are worse than your heating system breaking down on a chilly night. Professional inspections help catch small issues before they develop into major problems that require costly emergency repairs. By addressing worn components or faulty electrical connections early, you can enjoy peace of mind knowing your system is far less likely to leave you in the cold. Promote Energy-Efficiency Heating your home can account for a significant portion of your energy bill during the fall and winter months. A professional inspection helps ensure your system is operating at peak efficiency. Technicians can identify clogged filters, worn parts, or airflow issues that force your system to work harder than necessary. Improve Indoor Air Quality Your heating system plays an important role in the air you and your family breathe. Dust, dirt, and allergens can build up in the system over time and circulate throughout your home when the heater is running. During an inspection, a technician can clean components, change filters, and make sure your system isn’t spreading pollutants. This is especially beneficial for households with seniors or individuals with allergies or respiratory concerns. Help Ensure Safety in Your Home Perhaps the most critical reason for a fall inspection is safety. Heating systems that burn fuel can develop dangerous issues like gas leaks or carbon monoxide buildup if not properly maintained. A professional technician will check for these hazards, helping to ensure your family stays safe while keeping warm through the season.

When summer heat rolls in, your home's air conditioning system becomes essential for comfort and safety. But like any mechanical system, your AC unit can develop issues over time. If these problems are caught early, you may be able to avoid a complete breakdown and costlier repairs. Understanding the warning signs of AC trouble can help you know when to call a professional before a minor issue becomes a major headache. At River City Heating & Air, we provide expert AC repair in the greater Bismarck, ND area. Here are four common signs that your home's AC system is in need of service. Weak Airflow from Vents If you’ve noticed that the airflow coming from your vents feels weaker than usual, this may be a sign that your AC system is struggling. Weak airflow could be caused by a clogged air filter, ductwork issues, or a failing blower motor. Regardless of the cause, limited airflow makes it harder to cool your home efficiently and can lead to uneven temperatures from room to room. It’s a sign that something in the system needs attention. Warm Air Instead of Cool Air When your AC system blows warm or room-temperature air, even though the thermostat is set to cooling mode, there’s likely a significant issue. This could stem from low refrigerant levels or a malfunctioning compressor. Whatever the cause, it means your AC isn’t performing its primary function. Warm air output should always be investigated promptly to restore comfort and prevent further damage. Strange Noises During Operation An air conditioning system should run relatively quietly, with only a soft hum or whoosh of air being noticeable. If you start hearing grinding, squealing, clanging, or banging sounds, it’s often a sign that a mechanical component is loose or failing. These sounds might indicate problems with the fan motor, belts, or internal parts of the compressor. Ignoring these noises can lead to system failure, so it's best to call an HVAC technician for an inspection. Unusually High Energy Bills If your energy bills have suddenly spiked without a corresponding increase in usage, your AC system may be the culprit. Aging or malfunctioning components force the system to work harder, drawing more energy to maintain the desired temperature. This inefficiency not only costs more in monthly bills, but also puts strain on your unit, increasing the risk of future repairs or replacements.

Your home’s air conditioning system works hard to keep you cool and comfortable during the warmer months. But like any mechanical system, it needs regular attention to stay efficient and reliable. While it might be tempting to skip routine service or handle maintenance on your own, having your AC professionally maintained offers significant long-term benefits. At River City Heating & Air, we provide expert HVAC maintenance in the greater Bismarck, ND area. Here are four reasons why it’s worth investing in professional maintenance for your home’s AC system. Improved Energy-Efficiency When an air conditioning system is cleaned and fine-tuned by a professional, it runs more efficiently. Dust buildup, clogged filters, and worn components can force your AC to work harder than necessary, leading to higher energy bills. The technician can inspect, clean, and optimize the system, helping it use less electricity to cool your home. This improved efficiency not only lowers monthly utility costs, but also reduces your environmental impact. Prevent Breakdowns on Hot Days One of the biggest advantages of professional maintenance is the ability to catch small problems before they turn into major repairs. Technicians are trained to identify early signs of wear, damage, or malfunction during routine inspections. By addressing these issues proactively, you reduce the risk of your AC system breaking down unexpectedly in the middle of a heatwave. Fewer breakdowns mean less inconvenience and fewer emergency service calls. Longer System Lifespan Regular maintenance helps extend the life of your air conditioning system. Just like regular oil changes help your car’s engine last longer, professional AC service keeps all the parts of your cooling system working smoothly and in sync. When components are clean, lubricated, and adjusted properly, the system experiences less strain, reducing the chances of early failure. With proper care, your AC can deliver reliable performance for many years. Better Indoor Air Quality A well-maintained AC system does more than just cool the air—it also helps filter out dust, pollen, and other airborne contaminants. When filters and coils are dirty, those particles can circulate through your home, impacting air quality. During a professional tune-up, the technician can clean or replace filters and inspect the system to help ensure it’s promoting healthy air in your living space.

As temperatures rise during the summer months, so can your utility bills—especially if your air conditioning system is working overtime. While staying cool is essential, there are smart ways to manage your energy use without sacrificing comfort. With a few practical changes, you can reduce strain on your AC system and help keep your electricity costs in check. Here are five tips for keeping your AC bill lower this summer. Use a Programmable Thermostat One of the easiest ways to control your cooling costs is by using a programmable thermostat. This allows you to set temperature schedules that match your daily routine. For example, you can set the temperature higher when you're away from home and lower it when you're back. This helps your system run more efficiently and prevents unnecessary energy use. Close Curtains and Blinds During the Day Sunlight streaming through your windows can significantly increase the indoor temperature, forcing your AC to work harder. Keeping your curtains or blinds closed during the hottest parts of the day can reduce indoor heat gain and help maintain a cooler environment. Seal Air Leaks and Insulate Properly If your home has air leaks or inadequate insulation, cooled air can escape, and hot outdoor air can enter. This makes your AC system run longer and work harder than it needs to. Sealing gaps around windows, doors, and ductwork can help prevent air loss. Making sure your attic and walls are well-insulated will also help your home retain cool air longer, improving overall efficiency. Use Fans to Support Cooling Ceiling fans can help circulate air more effectively, potentially allowing you to raise the thermostat a few degrees without losing comfort. Fans create a wind-chill effect that makes you feel cooler, even if the air temperature remains the same. Just remember to turn fans off when you leave the room, as they cool people, not spaces. Maintain Your AC System Regular maintenance is key to keeping your air conditioner running at peak performance. This includes changing the air filter every one to three months, cleaning the condenser coils, and checking refrigerant levels. Scheduling an annual tune-up with a professional technician can also catch minor issues before they turn into costly repairs, helping your system run smoothly all season long.

When temperatures start to rise, your air conditioning system becomes one of the most important features of your home. Taking the time to prepare your system before the peak of the season can prevent unexpected breakdowns and ensure maximum efficiency when you need it most. At River City Heating & Air, we provide expert AC service in the greater Bismarck, ND area. Here are five ways to get your AC system summer-ready. Schedule a Professional Tune-Up One of the best steps you can take before summer is to schedule a professional inspection and tune-up. An HVAC technician will check all the key components of your system. Routine maintenance ensures that your system is running smoothly and efficiently. A professional can also catch any minor issues before they turn into major repairs during a heatwave. Replace or Clean the Air Filter Your AC’s air filter plays a big role in how well your system runs. A dirty or clogged filter restricts airflow, making your AC work harder to cool your home. This can reduce energy-efficiency and can also lead to poor indoor air quality. Check the filter at the start of the season and replace it if it looks dirty. If you have pets or allergies, consider replacing it more frequently throughout the summer. Clean the Outdoor Unit Your AC’s outdoor condenser unit is exposed to the elements year-round. Leaves, dirt, and debris can build up around it, reducing its ability to release heat. Before the hot weather hits, make sure the area around the unit is clear and free of obstructions. Check and Seal Ductwork Leaky or poorly sealed ductwork can lead to cooled air escaping before it reaches the rooms in your home. This means your AC has to work harder, which drives up your energy bills and reduces comfort. For a thorough inspection, consider having a professional evaluate your entire duct system. Test the Thermostat Before the summer heat hits full force, test your thermostat to make sure it’s reading temperatures accurately. Consider upgrading to a programmable or smart thermostat if you haven’t already. These devices allow you to set schedules and control temperatures more precisely, helping you stay cool and save energy during the hottest months of the year.

The ductwork in a commercial building plays a crucial role in maintaining proper airflow, temperature control, and indoor air quality. If the ductwork is damaged or inefficient, it can lead to increased energy costs and reduced comfort. At River City Heating & Air, we provide expert commercial ductwork services in the greater Bismarck, ND area. Here are four signs of an issue with your commercial building’s ductwork. Uneven Heating and Cooling Throughout the Building One of the most common signs of ductwork problems is inconsistent temperatures in different areas of the building. If some rooms are significantly warmer or cooler than others, it could indicate that air is not being distributed properly. Leaks, blockages, or poorly designed ducts can restrict airflow, making it difficult for your HVAC system to maintain even temperatures. Employees and customers may complain about discomfort, which can negatively impact productivity and business operations. Rising Energy Bills Without Increased Usage If your commercial building's energy bills have been steadily increasing despite no major changes in usage, your ductwork may be to blame. Leaky or damaged ducts allow conditioned air to escape before it reaches its intended destination, forcing your HVAC system to work harder to compensate for the lost air. This increased strain on the system leads to higher energy consumption and unnecessary costs. Unusual Noises Coming from the Ducts While some noise from HVAC systems is normal, loud rattling, banging, or whistling sounds coming from the ductwork could indicate loose connections, air leaks, or structural damage. Vibrations from loose duct sections can create noticeable noises, while whistling sounds often signal gaps where air is escaping. If left unaddressed, these issues can worsen. Having a professional inspect the ductwork can help identify and resolve these problems before they escalate. Weak or Inconsistent Airflow from Vents If some areas of your commercial building experience weak or fluctuating airflow, it may be due to ductwork obstructions or damage. Poor airflow not only affects comfort, but can also put unnecessary strain on heating and cooling equipment, shortening its lifespan.

A properly functioning furnace is essential for keeping your home warm and comfortable. While some minor furnace issues can be resolved with simple maintenance, others require more complex work to ensure safety and efficiency. Ignoring these problems could lead to more significant damage or even hazardous conditions in your home. At River City Heating & Air, we provide expert furnace service in the greater Bismarck, ND area. Here are four common furnace problems that should be addressed by a qualified HVAC technician. Frequent Cycling If your furnace is constantly turning on and off in short bursts, known as short cycling, it could indicate a serious issue. A clogged air filter or a malfunctioning thermostat may be to blame. However, short cycling can also result from a more complex problem, such as a cracked heat exchanger. An HVAC technician can diagnose the exact cause and make the necessary repairs. Pilot Light or Ignition Problems Gas furnaces rely on either a standing pilot light or an electronic ignition system to function properly. If the pilot light frequently goes out or the electronic ignition fails, the furnace won’t be able to generate heat. Issues with the thermocouple or gas supply can contribute to ignition problems. Because these components involve gas and electrical connections, attempting DIY repairs can be dangerous. An HVAC professional can safely assess and fix the issue. Unusual Noises A furnace naturally makes some noise when operating, but strange sounds like screeching or rattling indicate an underlying problem. Screeching can result from a worn-out blower motor belt. Rattling sounds often point to loose components or a cracked heat exchanger. Since some of these issues can lead to dangerous conditions, it’s crucial to have a technician inspect and repair the furnace immediately. Gas Leaks or Carbon Monoxide Issues One of the most dangerous furnace problems is a gas leak or carbon monoxide leak. If you notice a rotten egg smell, feel dizzy, or experience flu-like symptoms while your furnace is running, leave your home immediately and call an HVAC technician. Regular furnace inspections can help detect leaks early and prevent life-threatening exposure.

For several good reasons, tankless water heaters have gained popularity in recent years. As opposed to traditional water heaters with large storage tanks, tankless models heat water only when you need it. This modern approach to water heating offers several benefits that make it an appealing choice for many homeowners. At River City Heating & Air, we provide expert tankless water heater installation in the greater Bismarck, ND area. Here’s a look at five advantages of tankless water heaters. Energy-Efficiency One of the biggest benefits of a tankless water heater is its energy-efficiency. Traditional water heaters continuously heat and reheat water stored in a tank, which can lead to significant energy loss over time. Tankless systems, on the other hand, only activate when you turn on a hot water tap. This on-demand operation reduces energy consumption, leading to lower utility bills and a smaller environmental footprint. Unlimited Hot Water With a tankless water heater, you don’t have to worry about running out of hot water during a long shower or when multiple appliances are in use. These systems heat water as it flows through the unit, providing a continuous supply. Even with a large family, a tankless water heater can meet high-demand needs without the limitations of a storage tank. Space-Saving Design Traditional water heaters with large tanks can take up considerable space in your home. In contrast, tankless water heaters are compact and can be mounted on a wall, freeing up valuable floor space. This is particularly beneficial for smaller homes or apartments where storage space is at a premium. Longer Lifespan Tankless water heaters generally last longer than traditional tank-style models. While a conventional water heater may last around 8 to 12 years, tankless units often have a lifespan of 20 years or more with proper maintenance. This durability makes them a cost-effective investment, as you won’t need to replace the system as frequently. Reduced Risk of Water Damage Since tankless water heaters do not rely on a large storage tank, you don’t face the risk of tank failure causing water damage to your home. Traditional water heaters can develop issues like rust, which may lead to leaks. With a tankless system, you eliminate the worry of flooding from a tank failure.
