Prepare Your HVAC System for the Fall
info • October 14, 2019
Even though some days still feel like summer is lingering around here in Lexington, South Carolina, we promise that fall is here and the cold weather is approaching and will be here before we know it. That means that your heating and air conditioning needs some TLC before the seasons begin to drastically change. At Brian’s Heating & Cooling, we want to make sure that you are fully prepared for the colder weather ahead and can stay warm and cozy all fall and winter long. Here are a few things you can do to be proactive and prepare your HVAC system for the fall weather ahead:
- Maintenance
- Replace Air Filters
- Consider an Upgrade
- Start Warming Up Your Unit
Conduct Maintenance and Clean Your Units
If you have a furnace, a heat pump or a packaged system, it is important that you schedule a maintenance visit with your HVAC contractor before the cold weather arrives. Additionally, you should also conduct some do it yourself seasonal cleaning on and around your outdoor equipment. You can clean and enhance your system’s efficiency and performance by just making sure that nothing is blocking your outdoor units and that all debris is off of your unit. For maintenance, just call your trusted HVAC contractor and set up an appointment time. This will ensure your equipment is working optimally and ready to provide you heat in the coming months.
Replace Your Air Filters
The general rule of thumb is to change your air filters whenever the season changes. That means you should be changing your filters every three months. It is something that takes very little time to do and can improve your HVAC system’s productivity by 15%. That means more energy savings and improved comfort inside of your home. Make sure you are staying on top of your air filter game, it can make a huge difference to your wallet and to your comfort.
Look Into Buying an Upgrade
This does not apply to everyone but it could apply to some. If your HVAC system is over 10 years old, you have probably been thinking about when you are going to upgrade your system. If you are noticing a change in the overall comfort level of your home, you may be in need of an upgrade as well. The best time to upgrade your system is during the fall because the weather is not too hot and not too cold. If you have been looking for a sign to replace your system, consider this your sign. Contact your local HVAC contractor to see what option is right for you and your home.
Begin to Warm Up Your Heating Unit
Finally, begin to warm up your heating unit to ensure it is working properly after not being used for a good bit of the year. Just like we as humans need to warm up before we go for a run or workout, the same principle applies for your heating unit. Regular use keeps the motor hot and your system loose. It’s not too early to start running your heating unit to get it warmed up for the fall and winter weather ahead of us.
If you’ve lived in Lexington, SC for long, you know spring doesn’t stay mild for very long. One day feels cool and breezy — the next feels hot, humid, and sticky. And while most homeowners think about their HVAC system mainly in terms of temperature, your system also plays a major role in controlling humidity inside your home. At Brian's Heating & Cooling, we often hear homeowners say things like: “My house feels damp even when the AC is running.” “The temperature says 72°, but it still feels uncomfortable.” “Why does my home feel sticky this time of year?” The answer is usually humidity — and spring in South Carolina is the perfect time for these issues to show up. Why Spring Humidity Matters in Lexington, SC As outdoor temperatures rise, moisture levels in the air increase too. Your air conditioner naturally removes some humidity during the cooling process, but if your system isn’t operating efficiently, excess moisture can linger inside your home. Too much indoor humidity can lead to: Sticky or clammy indoor air Musty odors Increased allergy symptoms Poor sleep and comfort Mold or mildew growth Higher energy bills Even worse, high humidity can make your home feel warmer than it actually is — causing you to lower the thermostat and put extra strain on your HVAC system. Signs Your HVAC System May Not Be Managing Humidity Properly Not sure if humidity is becoming a problem in your home? Here are a few common warning signs: 1. Your Home Feels Muggy If the air feels heavy or damp, your system may not be removing enough moisture during cooling cycles. 2. Condensation Around Windows Foggy windows or moisture buildup can indicate excess humidity indoors. 3. Musty Smells A damp smell near vents, closets, or certain rooms could mean moisture is lingering too long. 4. Uneven Comfort Some rooms may feel cooler while others still feel sticky or warm. 5. Your AC Runs Constantly An oversized or struggling system may cool quickly without properly dehumidifying the air. How To Improve Indoor Comfort This Spring The good news is there are several ways to improve humidity control and overall comfort in your Lexington home. Replace Your Air Filter Regularly Dirty filters restrict airflow and make your system work harder. A clean filter helps maintain proper airflow and system efficiency. Keep Vents Open & Unblocked Blocked vents can reduce circulation and create uneven humidity throughout the home. Upgrade to a Smart Thermostat Modern thermostats can help manage temperature and humidity more efficiently, especially during unpredictable spring weather. Schedule Seasonal HVAC Maintenance A professional tune-up allows technicians to inspect airflow, coils, refrigerant levels, and drainage systems — all of which impact humidity control. Consider a Whole-Home Dehumidifier For homes that constantly struggle with excess moisture, a dedicated dehumidifier can dramatically improve comfort and indoor air quality. Don’t Wait Until Summer Heat Arrives Spring is one of the best times to address comfort issues before the intense South Carolina summer arrives. If your home already feels sticky now, those problems will likely become worse once temperatures climb into the 90s. At Brian's Heating & Cooling, we help homeowners throughout Lexington and the Midlands stay comfortable with expert HVAC maintenance, repairs, and indoor air quality solutions designed for South Carolina’s climate. If your home feels humid, uncomfortable, or your AC system isn’t keeping up, now is the perfect time to schedule a professional inspection before summer arrives.

If you’ve recently turned on your air conditioner and noticed a strange smell, you’re not alone. Every spring, homeowners in Lexington, SC start up their AC systems for the first time in months—and quickly realize something doesn’t smell right. At Brian’s Heating & Cooling, we get frequent calls this time of year about AC odors, and while some are harmless, others can point to bigger HVAC issues. Here’s what those smells mean—and when it’s time to call for AC repair in Lexington, SC. Why Does My AC Smell When I Turn It On? When your air conditioner sits unused during the winter, dust, moisture, and even bacteria can build up inside the system. Once you turn it back on in the spring, those odors get pushed through your vents and into your home. In Lexington’s humid climate, this buildup can happen quickly, making spring the most common time for air conditioner smell issues. Common AC Smells and What They Mean Musty Smell from AC Vents If your AC smells musty, it’s usually caused by moisture buildup in your system. This can lead to mold or mildew growth in areas like your evaporator coil or drain line. Burning Smell When AC Turns On A slight burning smell when you first turn on your AC can be normal—it’s often just dust burning off internal components. However, if the smell continues, it could signal an electrical issue and may require HVAC repair in Lexington, SC. Dirty Sock Smell from Air Conditioner This unpleasant smell is often caused by bacteria buildup on your evaporator coil—a common issue in humid areas like the Midlands. If your AC smells like dirty socks, it’s time for a professional cleaning. Chemical Smell from AC Unit A strong chemical or sweet smell could indicate a refrigerant leak. This is not something to ignore and should be addressed by a licensed technician right away. Burning Plastic or Electrical Smell If you notice a sharp, electrical odor, turn off your system immediately. This could be a wiring issue and requires immediate attention. How to Get Rid of AC Smells If you’re dealing with a smelly AC unit, here are a few steps you can take: Replace your air filter to improve airflow and reduce odors Check your thermostat settings to ensure proper system operation Clear debris from your outdoor unit Schedule a professional HVAC tune-up Routine maintenance is the best way to prevent AC odor problems and improve your system’s performance. When to Call for AC Repair in Lexington, SC While some smells are temporary, others shouldn’t be ignored.

As February winds down here in Lexington, SC, we’re in that familiar South Carolina transition period—cool mornings, mild afternoons, and just enough chilly nights to keep the heat running.

A little attention now can help prevent breakdowns when temperatures (and humidity) climb. Here’s what Lexington homeowners should be thinking about as we head toward spring. Don’t Wait for the First Hot Day to Test Your AC Many homeowners don’t realize their air conditioner has an issue until the first warm day hits—and by then, HVAC companies across Lexington are already busy. Now is the perfect time to: Turn your AC on briefly to ensure it’s running smoothly Listen for unusual sounds Check that cool air is coming from vents Make sure your thermostat switches properly between heating and cooling If something seems off, addressing it early is almost always faster and less stressful than waiting for a 85° afternoon in April. Replace Your Air Filter Before Pollen Season Hits If you’ve lived in the Midlands for even one spring, you know what’s coming: pollen everywhere. That yellow-green dust doesn’t just coat your car—it also impacts your indoor air quality. Replacing your HVAC air filter now helps: Improve airflow and system efficiency Reduce dust and allergens inside your home Protect your system from strain Keep indoor air cleaner during peak pollen weeks For most homes, changing filters every 1–3 months is ideal. If you have pets, allergies, or a larger household, you may benefit from more frequent changes. Why Spring HVAC Maintenance Matters in South Carolina South Carolina’s humidity and long cooling season put a lot of stress on air conditioning systems. A spring tune-up helps ensure your system is ready for months of steady use. Professional maintenance typically includes: Cleaning coils and components Checking refrigerant levels Inspecting electrical connections Testing thermostat operation Ensuring proper airflow and efficiency Catching small issues now can prevent larger repairs—or even system failures—once temperatures rise. Heat Pump Owners: Pay Attention to the Transition If your home uses a heat pump, this time of year is especially important. Your system will soon switch from heating mode to cooling mode for the long haul. A seasonal check can confirm: The reversing valve is working properly Defrost and cooling functions are operating correctly Airflow is balanced throughout your home Ensuring everything transitions smoothly now helps avoid performance issues later in spring and summer.
