Common Furnace Problems
October 24, 2022
Some furnace problems happen more often than others. In some cases what might seem like a major problem with your furnace could actually be something that is an easy fix. The A/C Rescue, LLC team has put together a list of some of the most common furnace problems that our team sees here in King, NC. Keep reading below to learn more!
Furnace Not Producing Heat
Your furnace has one main job, to distribute heat throughout your Eden, NC home. If your furnace isn’t producing heat, it’s often a cause for alarm but in some instances, it might be a small issue. One of the reasons your furnace might be blowing air but not hot air is if the fan setting on your thermostat is set to ON instead of AUTO. Another reason is if your furnace isn’t set to heat. We know it sounds silly but many times someone will accidentally change the thermostat settings and this is the cause for no hot air in your home. Be sure to check your thermostat settings before calling your local HVAC professional for furnace repair help.
Furnace Turning On and Off
If your furnace is short cycling and constantly turning on and off, that is a sign that something is wrong. Short cycling is usually due to a lack of airflow in your furnace which causes it to overheat. A clogged air filter can restrict airflow resulting in overheating your furnace and the safety switch going off. If you notice your furnace is turning on and off frequently, make sure to check and replace your air filters appropriately.
Furnace is Making Strange Noises
Finally, if your furnace is making strange noises, it might be time to call your local Eden, NC HVAC contractor for help. If you hear any loud banging, rattling, or knocking noises coming from your heating unit, something has likely come loose and needs to be adjusted or tightened by a professional.

When the North Carolina summer heat kicks in, a dependable air conditioner isn’t a luxury—it’s a necessity. But what happens when your AC starts acting up? The big question most homeowners face is whether to repair the existing unit or replace it altogether. At A/C Rescue, LLC, we know this decision can feel overwhelming, so here are some key factors to help guide you. 1. Age of Your AC System The typical lifespan of an air conditioner is 10–15 years. If your unit is older than that and giving you frequent problems, replacement is usually the smarter long-term investment. On the other hand, if your AC is under 10 years old and has been well maintained, a repair could extend its life for several more seasons. 2. Frequency of Repairs Think about how often you’ve had to call for service. If breakdowns are becoming a routine (especially during peak summer months), those repair bills can quickly add up. A new unit may cost more upfront, but it often saves money in the long run compared to constant fixes. 3. Energy Efficiency Older systems are generally less efficient, which means higher monthly utility bills. Newer AC units are designed to meet stricter energy efficiency standards, helping you stay cool while lowering energy costs. If your unit struggles to keep up—or your bills are steadily rising—replacement may be the better choice. 4. Cost of the Repair A good rule of thumb: if the cost of the repair is 50% or more of the price of a new unit, it’s usually better to replace. Minor issues like a clogged drain line or a faulty capacitor are often worth repairing, but major component failures (like the compressor) may not be. 5. Comfort & Air Quality If your AC runs but doesn’t keep your home evenly cool, or if you’re noticing excess humidity or poor air quality, your system may not be performing the way it should. A newer unit can offer better comfort, quieter operation, and improved indoor air quality. Final Thoughts Every home and situation is unique, which is why it helps to get expert advice before making the decision. At A/C Rescue, LLC, we’re here to help King, NC homeowners weigh their options and choose the solution that makes the most sense—whether that’s a cost-effective repair or a brand-new system.

Has your air conditioner been running non-stop lately—even when it's not scorching outside? If so, you’re not alone. Here in King and throughout the Piedmont Triad, we get a lot of calls this time of year from homeowners noticing their AC seems to never take a break. While it’s normal for your system to run more often during our hot, humid summers, a constantly running AC could be a sign that something’s not quite right. Let’s take a closer look at what might be going on—and what you can do to fix it. 1. The North Carolina Heat Is No Joke Summer in King means sticky humidity and long stretches of 90°+ days. In this kind of heat, it’s not unusual for your AC to run longer cycles to keep your home comfortable. But if it never shuts off, or struggles to reach your thermostat setting, that’s a red flag. What to do: First, make sure your thermostat settings are realistic—setting it too low (like 68°F in July) can cause your system to work overtime. If your system still won’t cycle off at a reasonable setting, it may need professional attention. 2. Dirty Air Filter A clogged filter restricts airflow and makes your system work harder than it should, causing longer run times and lower efficiency. What to do: Check your filter. If it's dirty—or if you can’t remember the last time you changed it—it’s time for a replacement. We recommend checking filters monthly and changing them every 1–3 months, depending on your home and usage. 3. Thermostat Issues Sometimes the problem isn’t the AC unit—it’s the thermostat. If it's malfunctioning or set to “fan on” instead of “auto,” your system may seem like it's always running. What to do: Double-check that your thermostat is set to “auto,” so the fan only runs during active cooling cycles. If the issue persists, consider having it tested or upgrading to a smart thermostat. A/C Rescue can help you pick the right one for your home and budget. 4. Leaky Ductwork Cool air could be escaping through holes, cracks, or loose connections in your ductwork—especially in attics, crawl spaces, or older homes. That lost air means your AC keeps running to make up for it. What to do: If you suspect a ductwork issue, schedule an inspection. Our team can test your system, seal leaks, and restore airflow where it matters—inside your home. 5. Wrong Size System If your AC is too small for your home, it will run constantly trying to cool the space. If it's too large, it may short cycle (turning on and off too often), which also strains the system and reduces efficiency. What to do: If your system has always struggled to keep up, we can perform a load calculation to see if your AC is properly sized. Upgrading to a properly matched unit can make a huge difference in comfort and costs. 6. It Needs Maintenance or Repairs Even the best AC systems need regular care. Low refrigerant, dirty condenser coils, or worn-out parts can all cause your system to run nonstop without effectively cooling your home. What to do: If it’s been more than a year since your last tune-up, now’s the time. Regular maintenance from A/C Rescue keeps your system running efficiently, helps catch small problems early, and extends the life of your equipment. Trust A/C Rescue, LLC to Keep You Comfortable A constantly running air conditioner doesn’t just wear out your system—it wears out your wallet too. Whether your system needs a quick fix, a filter change, or a full inspection, the team at A/C Rescue in King, NC is ready to help. 👉 Schedule your service appointment today and ask about our Priority Care Membership for year-round savings, faster service, and peace of mind.
When a summer heat wave hits King, NC, the last thing you want is for your air conditioner to stop working. Unfortunately, extreme temperatures often push aging or poorly maintained systems past their breaking point. At A/C Rescue, LLC , we’ve seen it all—and we know the warning signs to watch for before your A/C calls it quits. If you notice any of these red flags, don’t wait until your system fails in the middle of a 95-degree day. Call your local HVAC experts right away to stay safe, cool, and comfortable. 1. Warm Air Coming from the Vents If your A/C is blowing air that isn’t cold—or only slightly cooler than the room—it could mean your system is low on refrigerant, has a compressor problem, or a clogged filter is blocking airflow. Any of these issues can worsen quickly during a heat wave. 2. Weak or Inconsistent Airflow Does the airflow feel weaker in certain rooms? Or do your vents seem to have less power than they used to? Poor airflow could indicate a failing blower motor, blocked ducts, or an issue with your thermostat. In extreme heat, this can lead to uneven cooling and higher energy bills. 3. Unusual Noises or Smells A healthy A/C system should run quietly. Grinding, banging, or screeching sounds can signal mechanical problems, while musty or burning smells could mean mold or electrical issues. Both are signs your unit might be close to failure. 4. Frequent Cycling Your A/C should go through relatively consistent cooling cycles. If it’s turning on and off more frequently than usual—especially without lowering the indoor temperature—it’s a sign of trouble. Frequent cycling can burn out components faster, especially when your system is already under pressure from the heat. 5. Higher Than Normal Energy Bills Spikes in your electricity bill during summer are expected, but if yours suddenly jumps much higher than usual, your system may be working harder than it should. That strain can lead to breakdowns when the temperatures soar. 6. Water Leaks or Ice Build-Up Excess condensation, water pooling around your unit, or ice on the refrigerant lines are all signs of a system that's not working properly. These problems can rapidly escalate in high heat, possibly causing damage to your home or your system. 7. Your System Is 10+ Years Old If your A/C is more than a decade old and hasn’t had regular maintenance, a heat wave can be the final straw. Older units are more likely to fail when they’re running nonstop. Proactive replacement or repairs can save you from being stuck in the heat. Don’t Wait for a Total Breakdown At A/C Rescue, LLC , we specialize in keeping families in King and the surrounding areas cool, even in extreme summer weather. If your system is showing any of the signs above—or you just want peace of mind—schedule a tune-up or diagnostic visit today. Call us now or book online to make sure your A/C is ready before the next heat wave hits.
When summer hits King, NC, the heat and humidity can become unbearable without a reliable air conditioning system. At A/C Rescue, LLC, we understand just how important it is to stay cool and comfortable during the hottest months of the year. That’s why we’re sharing expert tips on how to prepare your HVAC system for a hot King summer—so you can enjoy efficient cooling and peace of mind all season long. 1. Schedule a Professional HVAC Tune-Up Before the peak of summer hits, schedule a preventative maintenance appointment with our certified HVAC technicians. During a tune-up, we’ll inspect, clean, and test all the key components of your system to make sure everything is running at peak performance. This can help prevent costly breakdowns and improve energy efficiency. 2. Replace or Clean Your Air Filters One of the simplest yet most important things you can do is check your air filter. Dirty or clogged filters can restrict airflow, forcing your system to work harder and reducing indoor air quality. We recommend replacing or cleaning your air filter every 1–3 months, especially during high-use seasons like summer. 3. Clear Debris Around Outdoor Units Your outdoor condenser unit needs room to breathe. Leaves, grass clippings, and other debris can block airflow and reduce efficiency. Make sure there is at least two feet of clear space around the unit and gently rinse the coils with a garden hose if they appear dirty. 4. Check Your Thermostat Settings Make sure your thermostat is set to “cool” and adjust the temperature for comfort and efficiency. Consider upgrading to a programmable or smart thermostat if you haven’t already—this allows for better control and can help lower your energy bills. 5. Seal Air Leaks in Your Home Your HVAC system works best when your home is properly sealed. Inspect windows, doors, and ductwork for any leaks or drafts that might let cool air escape. Sealing these areas can help maintain a consistent indoor temperature and reduce strain on your AC. 6. Consider an HVAC System Upgrade If your air conditioner is over 10-15 years old or needs frequent repairs, it might be time to consider upgrading to a newer, more energy-efficient model. A/C Rescue, LLC offers expert recommendations and installation services to ensure you get the right system for your home and budget.

As summer approaches in King, NC, your air conditioner becomes more important than ever. If your AC system struggled to keep up last year—or worse, broke down entirely—you might be wondering whether it's time to schedule a repair or consider replacing it altogether. At A/C Rescue, LLC, we help homeowners make the best decision for their comfort and budget. Here’s what you need to know when deciding whether to repair or replace your old air conditioner before the heat hits full swing. How Old Is Your Air Conditioner? One of the biggest factors in the repair vs. replace decision is the age of your system. Most air conditioners have a lifespan of around 10–15 years. If your AC is over a decade old and experiencing frequent issues, replacement might be the more cost-effective solution in the long run. Consider Repair If: The unit is less than 10 years old. Repairs are minor and infrequent. Your energy bills haven’t increased significantly. The system still cools your home evenly and reliably. In these cases, a timely repair can extend your system’s lifespan and keep it running smoothly through the summer months. Our expert technicians at A/C Rescue, LLC can quickly diagnose and fix common AC problems to get your home comfortable again fast. Consider Replacement If: Your AC is more than 12–15 years old. You're facing frequent breakdowns or costly repairs. Energy bills have spiked without a change in usage. Your home has hot or cold spots, or the system struggles to keep up. A new air conditioner may come with a higher upfront cost, but it offers greater efficiency, improved comfort, and long-term savings on energy bills. Plus, newer models often include smart features and improved air quality benefits. Don’t Wait Until It Breaks Waiting until your AC fails in the middle of a King, NC heatwave can leave you uncomfortable and scrambling for emergency repairs.

As the weather in King, NC starts to warm up, homeowners begin preparing for the heat of summer. One of the best ways to ensure your home stays comfortable during the hottest months is by scheduling an AC tune-up in the spring. At A/C Rescue, LLC, we recommend taking a proactive approach to HVAC maintenance, and here’s why spring is the perfect time to get your system serviced. Beat the Summer Rush Once temperatures soar, HVAC companies experience a surge in service calls from homeowners dealing with AC breakdowns.

Enhance Efficiency and Lower Energy Bills A well-maintained air conditioning system runs more efficiently, which means it uses less energy to keep your home cool. Regular tune-ups help identify and address minor issues before they turn into costly repairs, ultimately saving you money on utility bills throughout the summer. Extend the Lifespan of Your AC Unit Routine maintenance helps keep your AC unit in peak condition, preventing unnecessary wear and tear. By addressing potential problems early, you can extend the life of your system and delay the need for an expensive replacement. Improve Indoor Air Quality During the winter, dust and debris can accumulate in your HVAC system, which can negatively impact your indoor air quality. A spring tune-up includes cleaning essential components like filters and coils, ensuring that the air circulating in your home is clean and healthy.

As temperatures drop in King, NC, homeowners rely on their heating systems to keep their homes warm and comfortable. However, heating systems can develop problems, especially during peak usage. At A/C Rescue, LLC, we want to help you stay ahead of these issues with this guide to common heating problems and how to fix them. 1. Uneven Heating or Cold Spots Cause: Blocked vents, dirty filters, or issues with ductwork. Fix: Ensure all vents are open and unobstructed. Replace or clean your air filter regularly. If the issue persists, have a professional inspect your ductwork for leaks or blockages. 2. Furnace Blowing Cold Air Cause: A malfunctioning thermostat, a clogged filter, or a pilot light issue. Fix: Check your thermostat settings to ensure it's set to "heat" and the temperature is appropriate. Replace dirty air filters to improve airflow. If your pilot light is out, relight it or contact a professional if you’re unsure how to do it safely. 3. Heater Won’t Turn On Cause: Tripped circuit breakers, thermostat issues, or a faulty ignition system. Fix: Check your breaker box and reset any tripped breakers. If the problem persists, inspect your thermostat or replace the batteries. For ignition issues, it's best to call a technician. 4. Strange Noises from the Heater Cause: Loose components, a failing blower motor, or ductwork expansion/contraction. Fix: If you hear banging, rattling, or squealing noises, turn off your system and inspect for loose screws or panels. If the sound continues, schedule a professional inspection to avoid further damage. 5. Short Cycling (Turning On & Off Frequently) Cause: Overheating, a dirty air filter, or an oversized furnace. Fix: Replace or clean your air filter to prevent overheating. If your system continues to short cycle, a technician can assess whether the furnace is properly sized for your home. 6. High Energy Bills Cause: Inefficient heating, clogged filters, or an aging system. Fix: Regular maintenance can improve efficiency. If your system is over 15 years old, consider upgrading to a more energy-efficient model. Prevent Heating Problems with Regular Maintenance Many common heating issues can be prevented with routine maintenance.

As temperatures drop in King, NC, your heater becomes essential for keeping your home warm and comfortable. But what if your heater is silently draining your wallet? Many homeowners don't realize their heating system may be costing more than it should due to inefficiencies or malfunctions. At A/C Rescue, LLC, we want to help you identify these signs early so you can save money and avoid unnecessary stress. 1. Skyrocketing Energy Bills If your energy bills have increased significantly compared to last winter, your heater may be working harder than necessary. Older systems or poorly maintained units often require more energy to deliver the same level of warmth. 2. Uneven Heating Do you notice some rooms are toasty while others remain chilly? Uneven heating can indicate your system is struggling to distribute warm air effectively, potentially wasting energy in the process. 3. Frequent Repairs If you’ve been calling for heater repairs multiple times a season, it might be time to assess whether it’s more cost-effective to replace your system. Frequent breakdowns are a common sign that your heater is nearing the end of its lifespan. 4. Strange Noises or Smells Loud banging, squealing, or rattling noises and persistent odors from your heater are red flags. These issues often indicate internal components are failing or debris is clogging your system, both of which can lead to higher operating costs. 5. Constant Running or Short Cycling If your heater runs continuously or frequently turns on and off (short cycling), it’s not operating efficiently. These issues can wear out your system prematurely and drive up your energy usage. 6. Dry or Stuffy Air An inefficient heating system may fail to maintain proper humidity levels in your home, leaving you with dry skin, irritated sinuses, and static electricity. A more efficient system can improve indoor air quality and comfort. 7. Outdated Equipment Heating systems typically last 10-15 years. If yours is older, it may not meet modern efficiency standards, even if it’s still functioning. Upgrading to a newer, energy-efficient model can lead to significant long-term savings.

Winter in King, NC, can bring chilly temperatures that make your HVAC system work overtime to keep your home comfortable. If your current system is outdated or inefficient, you could be losing money every month. Upgrading your HVAC system this season is not just about comfort—it’s a smart financial decision that can yield significant savings. Here’s how: 1. Improved Energy Efficiency Modern HVAC systems are designed to use less energy while providing superior heating performance. Advanced technology such as variable-speed motors and smart thermostats allows these systems to adapt to your home’s needs. This means less energy waste and lower utility bills. Older systems, especially those over 10-15 years old, tend to lose efficiency. By upgrading, you’ll likely see an immediate drop in your monthly heating costs. 2. Reduced Repair Costs As HVAC systems age, they require more frequent repairs, which can quickly add up. If you’ve been calling for repairs multiple times a year, it’s time to consider whether an upgrade would be more cost-effective. New systems come with warranties that cover many of the issues you might otherwise pay for out-of-pocket. 3. Eligibility for Rebates and Tax Incentives Upgrading your HVAC system could make you eligible for state or federal energy-efficiency rebates. Additionally, many newer systems qualify for tax incentives that reward homeowners for reducing their energy consumption. These financial benefits can significantly offset the initial cost of a new system. 4. Enhanced System Lifespan Investing in a new HVAC system means you’ll enjoy years of reliable performance. With proper maintenance, a modern system can last 15-20 years, saving you the cost of replacing parts or an entire unit prematurely. Plus, modern systems are built to handle extreme weather more effectively, ensuring you’re prepared for whatever winter brings to King, NC. 5. Better Air Quality and Comfort A new HVAC system doesn’t just save money—it improves your living environment. Advanced filtration systems in newer models reduce allergens and pollutants in your home. Enhanced temperature control ensures you stay comfortable without overworking your system, which keeps energy costs down.

As winter approaches in King, NC, residents begin preparing for the inevitable drop in temperatures. While it's essential to keep your home cozy and warm, it's also crucial to ensure that your heating costs don't get out of control. At A/C Rescue, LLC, we understand how important it is to balance comfort and energy savings. To help you lower your heating costs this winter, we've compiled several practical tips to keep your home warm without breaking the bank. 1. Schedule Regular HVAC Maintenance A well-maintained heating system runs more efficiently, reducing energy consumption. Scheduling an annual furnace or heat pump inspection ensures that your system is running optimally and can prevent costly breakdowns. During the maintenance visit, our expert technicians at A/C Rescue, LLC will clean and inspect your system, change the air filter, and address any issues before they turn into expensive repairs. 2. Change Your Air Filters Regularly One of the easiest and most affordable ways to improve your heating efficiency is by changing the air filters regularly. Clogged filters restrict airflow, causing your heating system to work harder to warm your home. This can lead to higher energy bills and premature wear on your system. We recommend replacing your filters every 1-3 months to keep things running smoothly. 3. Seal Drafts and Insulate Your Home A well-insulated home is key to retaining heat and reducing the amount of energy needed to keep your space warm. Check for drafts around windows, doors, and even electrical outlets. You can seal gaps with weatherstripping or caulking. Additionally, adding insulation to your attic, walls, and floors will help maintain your home's temperature and reduce your heating costs significantly. 4. Invest in a Programmable Thermostat A programmable thermostat allows you to set your home’s temperature based on your schedule, ensuring you're not wasting energy while you're away. You can lower the temperature when you're at work or asleep, then have it warm up right before you return home or wake up. With a little adjustment, you can save money while still maintaining comfort. 5. Keep Your Vents Unblocked Make sure that vents and registers are not obstructed by furniture, curtains, or other items. Blocked vents reduce the airflow, causing your heating system to overwork. Clear any obstructions to ensure that warm air circulates properly throughout your home. 6. Use Space Heaters Wisely If you're only using certain rooms in your home, consider using a space heater to provide localized warmth instead of turning up the thermostat for the entire house. Just be sure to use space heaters safely and never leave them unattended. 7. Dress for Warmth Sometimes, the simplest solutions are the best. Wearing warm clothing, using blankets, and adding extra layers can help you stay comfortable without turning up the heat. The less you rely on your heating system, the more you'll save on your energy bills. 8. Upgrade Your Heating System If your furnace or heat pump is old and inefficient, it may be time for an upgrade. Modern heating systems are designed to use less energy while providing the same level of comfort. At A/C Rescue, LLC, we offer energy-efficient heating solutions that can save you money in the long run. By implementing these tips, you can stay warm and comfortable all winter without spending a fortune on heating costs. At A/C Rescue, LLC, we’re here to help you maintain a comfortable home while saving money.
