Signs of a Failing Furnace

As cooler weather settles into the High Country, many homeowners in Boone, NC are preparing their heating systems for the season ahead. If you’re considering a replacement or upgrade, one of the most common questions is: Should I choose a furnace or a heat pump? Both options can keep your home warm, but they work differently and have unique advantages. At Edmisten Heating & Cooling, we want to help you make an informed choice based on your comfort needs, home type, and budget. Furnaces: Traditional & Powerful Heating A furnace generates heat by burning fuel (usually natural gas or propane) or using electricity, then blowing the warm air through ductwork. Pros : Strong, consistent heat output — great for colder Boone winters Works quickly to heat larger homes Reliable with proper maintenance Considerations: Requires ductwork Gas furnaces need proper ventilation and regular safety checks Can use more energy compared to heat pumps during milder weather Heat Pumps: Efficient Year-Round Comfort A heat pump doesn’t create heat — it transfers it. In winter, it pulls heat energy from the outdoor air and moves it indoors. In summer, it reverses to provide cooling. Pros : Provides both heating and cooling in one system Highly energy-efficient, especially in moderate climates Lower monthly utility bills compared to electric furnaces Considerations : May struggle to keep up during extremely cold snaps in Boone Often needs a supplemental heat source (like a furnace or electric backup) Outdoor unit requires regular maintenance to stay efficient Which Is Right for You? Choose a Furnace if… you want strong, reliable heating power and don’t mind pairing it with a separate cooling system in summer. Choose a Heat Pump if… you want an energy-efficient, all-in-one system and are comfortable with the possibility of supplemental heat on the coldest mountain nights. Both furnaces and heat pumps can keep your Boone, NC home warm and comfortable this fall and winter. The best choice depends on your home’s setup, your budget, and how much efficiency matters to you. To learn more about some of the heat pumps and furnaces we carry and install here at Edmisten Heating & Cooling, check out our product pages. At Edmisten Heating & Cooling, we install and service both furnaces and heat pumps, and we’ll help you decide which system makes the most sense for your home. Call us today to schedule a consultation and get your home ready for the cooler months ahead.

Summers in Boone, NC might be cooler than in other parts of the state, but that doesn’t mean your HVAC system isn’t working hard. Between humidity, temperature swings, and mountain weather, your air conditioning system has its own unique challenges in the High Country. At Edmisten Heating & Cooling, we’ve spent years helping Boone homeowners stay comfortable all summer long. Here are the top 5 HVAC problems we see every summer—and what you can do to help prevent them. 1. Frozen Evaporator Coils Yes, even in the summer your system can freeze up. Frozen evaporator coils are often caused by restricted airflow (usually from a dirty air filter) or low refrigerant levels. When airflow drops, moisture condenses and freezes on the coil—causing your system to stop cooling effectively. What to watch for: Weak airflow from vents Ice visible on indoor unit or lines AC running but not cooling Pro tip: Change your air filter every 1–2 months and schedule regular maintenance to avoid this issue. 2. Low Refrigerant Levels Low refrigerant means your system can’t properly cool the air. This usually indicates a leak, which needs to be located and repaired. Boone’s elevation and shifting temps can increase wear on HVAC lines and joints, making leaks more likely over time. Signs include: Warm air blowing from vents Longer cooling cycles Hissing or bubbling sounds near the unit Solution: Call our team to locate the leak, recharge your system, and get things running smoothly again. 3. Clogged Condensate Drain Line Your AC removes moisture from the air, which drains through a line to the outside. But in humid climates—yes, even in the mountains—algae and debris can clog this line, causing water to back up into your home or shut off your system entirely. Common symptoms: Water around your indoor unit Musty odors Sudden AC shutdowns Regular inspections and cleaning during seasonal tune-ups can prevent blockages and water damage. 4. Thermostat Issues In Boone’s variable climate, we see thermostats struggle with incorrect readings or sudden system changes. Sometimes, it’s just an aging thermostat—or it could be a poor location (too close to windows or vents) throwing off your temperature control. What to look for: Inconsistent indoor temps System short cycling or not turning on Unresponsive or blank thermostat Consider upgrading to a programmable or smart thermostat to improve accuracy and efficiency. 5. Outdoor Unit Obstructions Boone’s lush summers are beautiful—but leaves, grass, and even small critters can obstruct your outdoor condenser unit. When airflow is restricted, your AC system has to work harder, which can lead to overheating and eventual failure. What you can do: Keep at least 2 feet of clearance around the unit Gently hose off debris Check for signs of nesting or animal activity Beat the Heat with Expert HVAC Care in Boone, NC At Edmisten Heating & Cooling, we know the unique HVAC challenges that come with living in the mountains. Our local team is here to keep your system running efficiently so you can stay cool and worry-free all summer long.

Summer in the High Country can be just as demanding on your air conditioner as any southern city—especially when temperatures spike in Boone, Blowing Rock, Banner Elk, and surrounding areas. While your AC is a lifesaver, constantly running it at full blast can lead to high energy bills, increased wear and tear, and even system failure. At Edmisten Heating & Cooling, we want to help you stay cool and efficient. Here’s how: 1. Use Ceiling Fans Wisely Ceiling fans don’t lower the temperature, but they do circulate cool air more effectively. Set them to rotate counterclockwise during summer months. This helps distribute the cool air from your AC and makes the room feel cooler—so you can raise the thermostat a few degrees without sacrificing comfort. 2. Close Curtains and Blinds During the Day Sunlight streaming through your windows is beautiful—but it also heats up your home fast. Invest in blackout curtains or thermal shades, especially on south- and west-facing windows. Blocking the sun during peak hours keeps your indoor temperature lower and reduces the strain on your air conditioner. 3. Seal Air Leaks Drafts aren’t just a winter problem. Leaky windows, doors, and ductwork can let cool air escape and let warm air in. If you’re noticing uneven cooling in your Boone home, it might be time to inspect your insulation and weatherstripping—or call us for a quick home energy audit. 4. Program Your Thermostat Smart thermostats are a game changer. Set it to increase the temperature slightly when you're at work or asleep. A 2–3 degree change during off-peak hours can make a big difference in your monthly bill without sacrificing comfort. Don’t have one? Edmisten Heating & Cooling can install and program a smart thermostat for you. Check out the smart thermostats we carry and install today. 5. Avoid Heat-Generating Appliances During the Hottest Hours Try to cook, do laundry, or run the dishwasher in the early morning or late evening. These appliances put off a surprising amount of heat and can make your AC work overtime. Consider grilling outdoors when it’s hot—Boone’s mountain evenings are perfect for it. 6. Keep Your HVAC System Maintained An efficient AC is a cool AC. Schedule seasonal maintenance with Edmisten Heating & Cooling to make sure your system is running at peak performance. We’ll clean coils, check refrigerant levels, and ensure all components are working properly—so you don’t run into surprises on a 90-degree day. 7. Add Shade Outside Your Home Planting trees, installing awnings, or placing reflective film on windows can all reduce the amount of heat that enters your home. Not only does this lower cooling needs, but it also adds to your property’s value and curb appeal. Trust Edmisten Heating & Cooling for Your Comfort Needs For over 50 years, Edmisten Heating & Cooling has helped Boone and the High Country beat the heat without breaking the bank. Whether you need a seasonal tune-up, a smart thermostat upgrade, or a full AC replacement, our experienced technicians are here to help. 📞 Call us at 828-264-0130

When spring rolls around in Boone, most of us are eager to open the windows, enjoy the fresh mountain air, and leave the winter chill behind. But there’s one thing too many homeowners forget during this seasonal transition— scheduling spring AC maintenance. At Edmisten Heating & Cooling, we know firsthand how important routine maintenance is, especially in a place like Boone, where the seasons change quickly and summers can be surprisingly warm. Skipping this crucial service might not seem like a big deal—until your AC breaks down during a July heatwave. Here’s why putting off spring maintenance can cost you more than you think. 1. Higher Energy Bills Without regular maintenance, your air conditioning system has to work harder to cool your home. Dirty coils, clogged filters, and low refrigerant levels can reduce efficiency, forcing your system to run longer and use more electricity. Boone residents who skip spring tune-ups often notice a spike in their energy bills as the summer heat sets in. 2. Unexpected Breakdowns Imagine your AC giving out during the hottest weekend in July—right when you have guests in town. That’s a common scenario we see in the Boone area. Most summer breakdowns are due to issues that could have been caught and resolved during a spring inspection. Our skilled technicians at Edmisten Heating & Cooling check for worn-out parts, refrigerant leaks, and electrical issues that might otherwise lead to costly repairs—or even full system replacement. 3. Shortened System Lifespan Your air conditioner is a major investment. Like a car, it needs regular servicing to stay in good shape. Skipping annual maintenance can shave years off its life. In Boone’s climate, where ACs often sit dormant during the cold months, spring is the perfect time to make sure everything is functioning properly before the summer demand hits. 4. Poor Indoor Air Quality Boone’s natural beauty brings with it pollen, dust, and other allergens—especially in spring. Without maintenance, your AC can circulate those particles throughout your home. A professional tune-up includes cleaning or replacing filters and inspecting your system for mold or mildew buildup, helping you breathe easier all summer long. 5. Reduced Comfort When You Need It Most Boone summers may not be as intense as those in the low country, but they can still get hot and humid—especially in July and August. A poorly maintained AC might not keep up when you need it most. Spring maintenance ensures your system runs at peak performance, keeping your home consistently cool and comfortable.

Spring in Boone, NC means blooming flowers, longer days, and—for many—seasonal allergies. While you’re enjoying the beauty of the High Country outdoors, you might not realize that the air inside your home could be making you feel worse. At Edmisten Heating & Cooling, we believe your home should be a place of comfort and clean air, especially during spring when pollen, dust, and other allergens are at their peak. Let’s look at why indoor air quality (IAQ) matters during spring—and how you can improve it. The Hidden Problem: Poor Indoor Air Quality Most people spend the majority of their time indoors, yet indoor air can often be 2–5 times more polluted than outdoor air. In spring, common indoor pollutants include: Pollen tracked in from outside Mold spores from excess humidity Dust mites stirred up during spring cleaning Pet dander VOCs (volatile organic compounds) from cleaning products If you're experiencing symptoms like sneezing, itchy eyes, or respiratory irritation inside your home, your indoor air quality could be to blame. How to Improve Indoor Air Quality This Spring 1. Upgrade Your Air Filter Standard filters trap large particles, but they may not catch fine allergens like pollen. High-efficiency filters or HEPA filters offer better protection—ask us what’s best for your system. 2. Add an Air Purifier A whole-home air purifier can eliminate a wide range of airborne pollutants, including bacteria, allergens, and odors. It's a smart investment for families dealing with allergies or asthma. 3. Control Humidity Boone’s spring weather can bring damp, rainy days that lead to high indoor humidity—a breeding ground for mold and mildew. A whole-home dehumidifier can help maintain ideal humidity levels between 30–50%. 4. Schedule a Duct Cleaning If it’s been years since your ducts were cleaned, now is the time. Dust, allergens, and debris build up in your ductwork and circulate every time your HVAC system runs. 5. Let Your HVAC System Help Your heating and cooling system plays a big role in indoor air quality. A clean, well-maintained system filters and circulates air more effectively, keeping your home fresher and healthier. Breathe Easier with Edmisten Heating & Cooling At Edmisten Heating & Cooling, we’re proud to help Boone homeowners breathe easier all season long.

As the spring season begins in Boone, NC, it’s time to start preparing your HVAC system for the warmer months ahead. With fluctuating temperatures and increased pollen in the air, ensuring your heating and cooling system is in peak condition is essential for comfort and efficiency. At Edmisten Heating & Cooling, we want to help you get your system ready for spring with these essential HVAC maintenance tips. 1. Replace Your Air Filters Spring brings pollen, dust, and other allergens that can quickly clog your air filters. A dirty filter reduces airflow, forcing your HVAC system to work harder and decreasing indoor air quality. Replacing your air filter every 1-3 months will help improve efficiency and keep the air in your home fresh and clean. 2. Schedule a Professional HVAC Tune-Up Routine maintenance is key to preventing costly repairs and ensuring your HVAC system runs efficiently. A professional tune-up includes checking refrigerant levels, inspecting electrical components, cleaning coils, and ensuring your system is operating at peak performance. Scheduling your spring maintenance now can help you avoid breakdowns when the temperatures rise. 3. Clean Your Outdoor Unit Winter debris, such as leaves and dirt, can accumulate around your outdoor condenser unit, restricting airflow and reducing efficiency. Take time to clear any debris and gently clean the unit to ensure proper operation. Keeping the area around your system clear of obstructions will also help maintain optimal performance. 4. Check Your Thermostat Settings As temperatures warm up, it’s a good time to adjust your thermostat settings for the season. Consider upgrading to a programmable or smart thermostat to optimize energy usage and maintain consistent comfort in your home. Setting your thermostat to an energy-efficient temperature when you're away can also help lower your utility bills. 5. Inspect Your Ductwork for Leaks Leaky or dirty ductwork can lead to energy waste and poor air quality. Check your ducts for any visible signs of damage or leaks, and consider having them professionally cleaned and sealed to improve airflow and efficiency. 6. Ensure Proper Insulation and Ventilation Proper insulation and ventilation are crucial for maintaining indoor comfort. Check for drafts, seal any air leaks, and make sure your vents are open and unobstructed to allow for proper airflow throughout your home. 7. Consider an HVAC Upgrade If your system is over 10-15 years old or struggling to keep up with temperature changes, it may be time for an upgrade. A new, energy-efficient HVAC system can improve performance, lower energy costs, and enhance overall comfort.

Winter in Boone, NC, can bring freezing temperatures, making a reliable furnace essential for keeping your home warm and comfortable. If your furnace is showing signs of trouble, ignoring them could lead to costly repairs or even a breakdown when you need it most. At Edmisten Heating & Cooling, we want to help you recognize the warning signs that your furnace needs immediate attention. 1. Unusual Noises While some noise from your furnace is normal, loud banging, rattling, or squealing sounds indicate potential mechanical issues. These noises could be caused by a loose component, a failing blower motor, or even a cracked heat exchanger.  2. Inconsistent Heating If some rooms in your home feel significantly colder than others, or if the furnace struggles to maintain a steady temperature, there could be an issue with the thermostat, ductwork, or a failing heating element. 3. Short Cycling A furnace that frequently turns on and off without completing a full heating cycle is short cycling. This could be due to a clogged air filter, a malfunctioning thermostat, or an overheating system. Short cycling not only reduces efficiency but can also cause further damage to your furnace. 4. Unusual Odors A persistent burning smell or the scent of gas should never be ignored. If you smell gas, turn off your furnace immediately, evacuate your home, and call for professional assistance. A musty or burning dust smell may be normal at the start of the season but should not persist. 5. Higher Energy Bills If you notice a sudden spike in your heating costs, your furnace may be working harder than necessary due to an issue such as a clogged filter, inefficient burners, or aging components. Addressing these problems early can save you money in the long run. 6. Yellow Pilot Light A healthy furnace flame should burn blue. If your pilot light is yellow or flickering, this could indicate a carbon monoxide leak, which is extremely dangerous. If you notice this issue, shut down your furnace and seek professional repair immediately. 7. Weak or No Airflow If your vents are producing weak airflow or no warm air at all, there could be an issue with the blower motor, a clogged air filter, or a blocked duct. Poor airflow reduces heating efficiency and can lead to further system strain. Don’t Wait – Call Edmisten Heating & Cooling Today! If you recognize any of these warning signs, don’t wait until your furnace fails completely. Edmisten Heating & Cooling is here to provide fast and reliable furnace repair services in Boone, NC.

Winter in Boone, NC, is picturesque, with its snow-covered landscapes and crisp mountain air. But as temperatures drop, heating bills can rise. At Edmisten Heating & Cooling, we’re here to help you stay cozy without breaking the bank. Check out these energy-saving tips to keep your home warm and your wallet happy this winter. 1. Schedule a Heating System Tune-Up Ensure your heating system is running efficiently with a professional tune-up. A well-maintained furnace or heat pump uses less energy and provides more consistent heat. Regular maintenance also extends the life of your equipment. 2. Seal Drafts and Insulate Drafty windows and doors are major culprits of heat loss. Use weatherstripping, caulk, or draft stoppers to seal gaps. Also, check your attic and walls for proper insulation, which helps retain heat and reduces the strain on your heating system. 3. Adjust Your Thermostat Lowering your thermostat by a few degrees when you're asleep or away can lead to significant savings. A programmable or smart thermostat can make these adjustments automatically, ensuring your home is warm when you need it and saving energy when you don’t. 4. Use Your Ceiling Fans Ceiling fans aren’t just for summer. Set your fan to rotate clockwise at a low speed to push warm air down from the ceiling, distributing heat more evenly throughout your rooms. 5. Take Advantage of Natural Sunlight Open your curtains and blinds during the day to let the sun naturally heat your home. Close them at night to add an extra layer of insulation and keep the warmth in. 6. Replace or Clean Air Filters Dirty air filters force your heating system to work harder, consuming more energy. Check your filters regularly and replace them as needed, typically every 1-3 months. 7. Consider Upgrading Your Heating System If your heating system is over 10-15 years old, it may be time for an upgrade. Modern systems are far more energy-efficient and can save you money in the long run. Edmisten Heating & Cooling offers energy-efficient solutions tailored to Boone’s winter climate. 8. Use Zone Heating If you don’t use every room in your house, consider zone heating. This strategy allows you to heat only the areas you use most, reducing unnecessary energy consumption. 9. Check Your Ductwork Leaky ducts can cause up to 30% of heat loss in your home. Have your ductwork inspected and sealed by professionals to ensure warm air reaches every corner of your home. 10. Bundle Up Sometimes, the simplest solutions are the most effective. Wearing warm layers, using cozy blankets, and adding rugs to your floors can reduce the need to crank up the heat. Stay Warm and Save with Edmisten Heating & Cooling By following these tips, you can enjoy a comfortable winter in Boone, NC, while saving energy and money. Need help with your heating system?
