4 Signs of a Problem with Your Commercial Building’s Ductwork

By Air Controls • March 11, 2025
Your commercial building’s ductwork plays a vital role in maintaining air quality, temperature control, and energy-efficiency. When ducts develop issues, it’s important to address them ASAP. At Air Controls, we provide expert commercial ductwork services in the greater Bozeman area. Here are four signs that your commercial building’s duct system may need attention. Uneven Heating and Cooling If some areas of your building feel much warmer or cooler than others, it could be a sign of ductwork problems. When ducts have leaks or blockages, they may fail to distribute air evenly throughout the space. This results in inconsistent temperatures, forcing your HVAC system to work harder to maintain comfort. If employees or tenants frequently complain about hot or cold spots, it’s time to have your ductwork inspected. Weak Airflow A noticeable decrease in airflow from vents is another common sign of duct issues. Weak airflow can stem from blockages caused by debris. If airflow is restricted, your HVAC system has to work harder to push air through, leading to increased energy consumption and potential strain on the system. Poor airflow can also reduce indoor air quality, making the environment less comfortable for occupants. Unusual Noises Coming from the Ducts While it’s normal for HVAC systems to produce some noise, loud rattling, banging, or whistling sounds coming from the ductwork can indicate problems. Loose or disconnected duct sections may rattle when air moves through them, while whistling noises can signal air leaks. These sounds suggest that your ductwork is not sealed properly, leading to energy loss and reduced system efficiency. If strange noises persist, it’s best to have the system professionally checked. Increased Energy Bills If your energy costs have risen unexpectedly without a clear reason, your ductwork may be to blame. Leaky or damaged ducts allow conditioned air to escape before it reaches its intended destination, causing your HVAC system to overwork. As a result, your heating and cooling expenses climb higher. If your energy bills keep increasing despite regular HVAC maintenance, an inspection of the duct system can help pinpoint any inefficiencies.

4 Quick Tips for Keeping Your Furnace in Great Shape

By Air Controls • February 11, 2025
Your furnace plays a crucial role in keeping your home warm and comfortable, especially during the colder months. To help ensure it operates efficiently and lasts for years to come, it’s worth taking some maintenance precautions. A well-maintained furnace not only provides consistent heating, but can also help reduce energy bills. Here are four important tips to keep your furnace in strong condition. Change the Air Filter Regularly One of the simplest ways to help maintain your furnace is to change the air filter regularly. A dirty or clogged filter restricts airflow, forcing the furnace to work harder and reducing its efficiency. Over time, this can lead to increased wear and tear and higher energy costs. Most filters should be replaced every one to three months, depending on usage and the type of filter. Checking and replacing the filter as needed enables optimal airflow and improves indoor air quality. Keep the Area Around the Furnace Clean Ensuring that the space around your furnace is clean and free of clutter is important for both safety and efficiency. Dust, pet hair, and debris can accumulate around the furnace, potentially getting inside and causing issues. Storing flammable materials near the furnace can also pose a fire hazard. Keeping proper clearance around the unit allows for good airflow and easy access for maintenance or repairs. A clean and unobstructed furnace is safer and more efficient. Check and Maintain the Thermostat Your furnace relies on the thermostat to regulate the temperature in your home, so it’s essential to keep it in good working order. If your thermostat is outdated or malfunctioning, it can lead to inconsistent heating and unnecessary strain on your furnace. Upgrading to a programmable thermostat allows you to set heating schedules, which can improve energy-efficiency and reduce heating costs. Schedule Annual Professional Maintenance Having your furnace inspected and serviced by a professional at least once a year is vital for its longevity and efficiency. During a maintenance visit, an HVAC technician will check for wear and tear and ensure all parts are functioning correctly. They can also identify potential issues before they turn into costly repairs. A well-maintained furnace runs more efficiently, providing reliable heat while consuming less energy. Heating System Maintenance in Bozeman, MT When you need heating system service in Bozeman and the surrounding area, contact Air Controls at (406) 587-6292.

Common Electrical Problems with Furnaces that Should Be Addressed ASAP

By Air Controls • January 10, 2025
Your furnace is a critical part of keeping your home warm and comfortable, especially during colder months. However, electrical issues can disrupt its functionality and compromise its performance. At Air Controls, our local HVAC company provides expert furnace repair in the greater Bozeman, MT area. Here are five common electrical problems in furnaces to watch out for. Malfunctioning Thermostat The thermostat serves as the brain of your heating system, regulating when and how much heat your furnace produces. If your thermostat isn’t working correctly, it may cause the furnace to run erratically or not at all. Issues could stem from faulty wiring or a calibration problem. Blown Fuses or Tripped Breakers Furnaces draw a significant amount of power, especially during peak operation. If the electrical circuit becomes overloaded, it can trip a breaker or blow a fuse. Frequent occurrences of this issue could indicate a deeper electrical problem within the furnace. Faulty Ignition System Modern furnaces often use electronic ignition systems rather than pilot lights to ignite the burners. If the ignition system malfunctions due to electrical issues, your furnace won’t be able to start properly. This problem is commonly caused by worn-out components, loose connections, or power supply issues. Damaged or Loose Wiring Over time, wiring in your furnace can become damaged due to wear and tear, pests, or corrosion. Loose or damaged wiring can cause intermittent performance issues, short circuits, or even complete system failure. Regular inspections can help identify and address wiring problems before they escalate. Faulty Blower Motor The blower motor is responsible for circulating warm air throughout your home. If the motor isn’t receiving the proper electrical current, it may operate inefficiently or stop working altogether. This can result in insufficient heating and uneven temperatures in your home. Faulty capacitors are a common cause of this issue. Furnace Repair in Bozeman, MT When you need heating system service in Bozeman and the surrounding area, contact Air Controls at (406) 587-6292.

4 Ways to Lower Your Heat Bill without Sacrificing Comfort

By Air Controls • December 10, 2024
As temperatures drop, heating costs can climb, straining your household budget. Fortunately, there are several effective strategies to reduce your heat bill without sacrificing comfort. From improving insulation to keeping up with HVAC maintenance, these methods can help you stay warm while saving reducing your heat bill. At Air Controls, we provide HVAC maintenance in Bozeman that optimizes your heating system’s efficiency, in turn lowering your heating expenses. Here’s a look at four tips for decreasing your heat bill. Improve Your Home’s Insulation Proper insulation is one of the most effective ways to reduce heating costs. Poorly insulated walls, attics, and floors allow warm air to escape, forcing your heating system to work harder. Upgrading your home’s insulation or sealing gaps around windows and doors can significantly improve energy-efficiency. By keeping warm air in and cold air out, you reduce the need for constant heating. Use a Programmable Thermostat A programmable thermostat allows you to customize your heating schedule based on your daily routine. By setting the temperature lower when you’re away or asleep and raising it when you’re home, you can save energy without compromising comfort. While there are some upfront costs with installing a programmable thermostat, you can achieve savings over time. Use Energy-Efficient Window Treatments Windows are a common source of heat loss, especially in older homes. Installing energy-efficient window treatments like thermal curtains or insulated shades can help retain heat. During the day, open south-facing curtains to let in natural sunlight and close them at night to trap the heat. This simple step can make a noticeable difference in your home’s warmth and your energy costs. Maintain Your Heating System A well-maintained heating system runs more efficiently and uses less energy. Regularly servicing your furnace or heat pump ensures that it operates at peak performance. Tasks like cleaning or replacing filters, inspecting ducts for leaks, and ensuring proper airflow can all contribute to reduced energy consumption and lower heating bills.

5 Signs of a Furnace Problem that You Shouldn’t Ignore

By Air Controls • November 7, 2024
Your furnace plays a crucial role in keeping your home comfortable and warm during the colder months, but when it starts showing signs of trouble, it’s best not to ignore them. Catching furnace issues early can help prevent breakdowns, improve efficiency, and even extend the life of the unit. At Air Controls, we provide expert furnace repair in the greater Bozeman area. Here are five common signs of a furnace problem. Unusual Noises Furnaces generally make some noise when running, but if you start hearing unusual sounds—like banging, rattling, or squealing—it’s often a sign of trouble. These noises can indicate anything from loose components to a failing blower motor or ignition problems. If you hear strange sounds, it’s best to call a technician to identify the problem before it worsens. Uneven Heating or Cold Spots If you notice that some rooms are warmer than others or that certain areas are consistently cold, it could point to an issue with your furnace. Uneven heating often results from problems like clogged air filters, leaky ducts, or an aging furnace struggling to distribute heat properly. Increased Heating Bills A sudden spike in your heating bills, despite using your furnace the same way as usual, is another red flag. When a furnace isn’t operating efficiently, it has to work harder to heat your home, using more energy in the process. Dirty filters, old parts, or general wear and tear can all lead to inefficiency, and a professional inspection can help diagnose the specific issue. Frequent Cycling If your furnace is frequently turning on and off, it’s experiencing what’s known as “short cycling.” This issue can arise from several causes, including a malfunctioning thermostat. Short cycling is not only hard on your furnace, but it also prevents your home from reaching the desired temperature, causing discomfort and wasted energy. Yellow Pilot Light A healthy pilot light on a gas furnace should burn blue. If it’s burning yellow, this could indicate a ventilation problem or even the presence of carbon monoxide—a colorless, odorless, and potentially dangerous gas. If you see a yellow flame, it’s crucial to have a technician inspect your furnace to ensure safe and proper operation.
