Summer in Sparta, NC can be downright brutal, and when the heat cranks up, your air conditioner becomes more than a luxury—it’s a necessity. But what happens when your AC starts showing signs of trouble just when you need it most? At Billings Heating & Cooling, we’ve seen too many families get caught off guard by an AC unit that gives out in the middle of a heatwave. Don’t let that be you! Here are the top signs your AC may not survive the summer—and what to do about it. 1. Weak Airflow If the air coming out of your vents feels weak or isn’t circulating properly, it could be a sign of a failing compressor or blocked ductwork. Either way, your AC won’t be able to keep up with the rising temps. Pro tip: If airflow is inconsistent from room to room, it’s time to schedule a professional inspection. 2. Strange Noises Your AC should hum—not clang, rattle, or screech. Unusual noises can mean anything from a loose part to a failing motor. Ignoring these sounds can lead to bigger (and more expensive) problems. 3. Warm Air Instead of Cool If your AC is blowing warm air, first check your thermostat settings. If everything looks good there and you’re still not getting cool air, you could be dealing with a refrigerant leak or compressor issue. 4. High Humidity Indoors Air conditioners are designed to regulate indoor humidity as well as temperature. If your home feels sticky even with the AC running, your system may be struggling to keep up—or it could be on its last leg. 5. Sky-High Energy Bills A sudden spike in your energy bill could mean your AC is working overtime to produce the same results. An aging or inefficient system may need a tune-up—or a full replacement. 6. Frequent Repairs If you’ve had to call for AC service more than once or twice already this year, it might be time to consider whether your system is worth saving. Constant breakdowns are a sure sign that your unit is wearing out. 7. AC Is 10+ Years Old Most air conditioners are built to last around 10–15 years with proper maintenance. If yours is nearing that range and showing any of the signs above, it may not survive another Shelby summer.

As the days get warmer and the chill of winter fades away, it’s the perfect time to ensure your HVAC system is ready for the change in seasons. At Billings Heating & Cooling in Sparta, NC, we understand the importance of a well-maintained system to keep your home comfortable year-round. Here are some essential spring HVAC maintenance tips to help you prepare your system for the warmer months ahead. 1. Change the Air Filter One of the easiest and most effective maintenance tasks you can do is replace your HVAC system’s air filter. Over time, filters become clogged with dust, dirt, and allergens, which can reduce airflow and strain the system. A clean air filter not only ensures your system runs efficiently but also improves your indoor air quality. Be sure to replace your filter every 1–3 months, especially during the spring when pollen levels are high. 2. Clean the Coils Both the evaporator and condenser coils in your HVAC unit can collect dirt and debris over time, reducing the efficiency of your system. Clean the coils regularly to maintain optimal performance. If you’re unsure how to clean them safely, our team at Billings Heating & Cooling can handle it for you. Dirty coils can cause your system to work harder, leading to higher energy bills. 3. Check the Ductwork Leaky ducts can cause your HVAC system to lose efficiency and increase your energy costs. Inspect the ducts for any signs of wear, gaps, or blockages, especially after the winter months. Sealing leaks and clearing obstructions will ensure the air circulates properly, keeping your home comfortable without overworking the system. 4. Test the Thermostat A malfunctioning thermostat can prevent your HVAC system from operating efficiently. Test your thermostat before the warmer weather sets in to ensure it’s properly regulating your home’s temperature. If your system is outdated or not responding correctly, it might be time to consider an upgrade. A smart thermostat can provide more control over your energy usage and comfort. 5. Inspect the Condensate Drain Your HVAC system’s condensate drain removes excess moisture created during cooling. If the drain is clogged, it could lead to water damage or system malfunctions. Clear any blockages and ensure the drain is flowing freely to prevent any issues during the warmer months. 6. Schedule Professional Maintenance While there are several tasks you can do yourself, scheduling a professional tune-up is essential. A certified technician from Billings Heating & Cooling can perform a thorough inspection of your system, check for potential issues, and ensure everything is functioning properly. Regular maintenance helps prolong the lifespan of your HVAC system and ensures it operates at peak efficiency. 7. Examine Insulation Proper insulation is essential for maintaining a comfortable home and maximizing energy efficiency. Check the insulation around your HVAC ducts and in areas such as attics and basements. Inadequate insulation can lead to energy loss, forcing your HVAC system to work harder and driving up your energy bills. 8. Clean the Outside Unit For homes with central air conditioning systems, it's important to clean the outdoor condenser unit. Remove leaves, twigs, and other debris from around the unit to ensure proper airflow. Trim any nearby shrubs or plants that could obstruct the system’s ventilation. Preparing your HVAC system for spring doesn’t have to be a daunting task. By following these simple tips and scheduling professional maintenance with Billings Heating & Cooling, you can ensure your system is ready to handle the warmer weather. Regular maintenance not only enhances system efficiency but also helps you avoid unexpected breakdowns and costly repairs.
