Stay Warm and Save Big with Modern Heating Solutions from ARCO Heating & Cooling As colder temperatures approach, it’s the perfect time to evaluate your home’s heating system. If your current setup is outdated, inefficient, or struggling to keep up, upgrading to a modern, energy-efficient system can make a big difference in both comfort and cost. At ARCO Heating & Cooling , we specialize in helping Missouri and Illinois homeowners find heating solutions that work smarter—not harder—through professional installation services and expert guidance. Why Energy Efficiency Matters in Winter Heating accounts for a major portion of winter energy bills, especially if your system is more than 10–15 years old. An energy-efficient heating solution not only lowers monthly utility costs but also reduces wear and tear on your HVAC system and shrinks your environmental footprint. When you choose the right system, you’re choosing better air quality, more consistent indoor temperatures, and long-term savings. Top Energy-Efficient Heating Systems for Your Home 1. Heat Pumps One of the most efficient systems available, heat pumps transfer heat instead of generating it. This makes them up to three times more efficient than traditional electric heating systems. They also double as an air conditioner in the summer! 2. High-Efficiency Furnaces Modern gas furnaces with an AFUE (Annual Fuel Utilization Efficiency) rating of 90% or higher provide powerful heating while minimizing energy waste. These units convert nearly all the fuel they consume directly into heat for your home. 3. Ductless Mini-Split Systems Ideal for smaller spaces or additions, ductless mini-splits allow you to heat specific areas independently. This zoning ability reduces energy waste and gives you more control over your home’s comfort. 4. Smart Thermostats Paired with a new system, a smart thermostat helps maximize efficiency by learning your routines and adjusting the temperature accordingly—even when you’re away. Is It Time to Upgrade? If you’ve noticed higher heating bills, uneven temperatures, strange noises, or frequent repairs, it might be time to consider an upgrade.

Understanding Humidity and How It Affects Your HVAC System When it comes to home comfort, temperature isn't the only factor at play. Humidity levels can significantly impact how your home feels, how well your HVAC system performs, and even your monthly energy bills. In this blog, we’ll dive into how humidity affects indoor comfort and introduce smart solutions from Arco Heating & Cooling that keep your home balanced year-round. Why Humidity Matters - More Than Just Moisture Humidity is the amount of water vapor in the air. When it's too high, your home can feel sticky, warm, and uncomfortable. When it's too low, it can lead to dry skin, irritated sinuses, and even damage to wood furnishings. Maintaining optimal indoor humidity (ideally between 30%–50%) is key for both comfort and health. How High Humidity Affects HVAC Performance System Strain and Reduced Efficiency Excess moisture forces your air conditioning system to work overtime. Your A/C isn’t just cooling the air—it’s also trying to remove water vapor. This added workload can: Increase energy consumption Cause uneven cooling Lead to premature wear and tear on components Mold and Mildew Risks High humidity creates an ideal environment for mold growth in ducts, vents, and other HVAC components. This can compromise indoor air quality and trigger allergies or respiratory issues. Low Humidity Isn’t Great Either Winter Woes In colder months, humidity levels naturally drop. When your HVAC system heats the air, it can become even drier, leading to: Cracked skin and lips Dry eyes and sore throats Static electricity Warped wood floors or furniture Signs Your Home Has Humidity Issues Foggy windows Musty odors Frequent allergy symptoms Hot or cold spots throughout the house Overworked HVAC system If you’re noticing these signs, it may be time to consider humidity control solutions. Arco Heating & Cooling’s Humidity Control Solutions Tailored for Missouri and Illinois Homes At Arco Heating & Cooling, we understand the regional climate challenges. That’s why we offer humidity control solutions designed to work with your existing HVAC system: Whole-home dehumidifiers : Remove excess moisture during hot, humid summers.

Is Your A/C on Its Last Legs? Here’s How to Know Your air conditioner is one of the most important appliances in your home—especially during sweltering summers. But like any machine, it wears out over time. Paying attention to warning signs can save you from a complete breakdown on the hottest day of the year and help you plan for a seamless replacement. In this guide, we’ll cover the key indicators that it’s time to replace your air conditioner and how Arco Heating & Cooling can make the process easy. 1. Your Unit Is Over 10–15 Years Old - Why Age Matters Most A/C systems have a lifespan of around 10 to 15 years. If your unit is approaching or past this age range, its efficiency and reliability drop significantly—and replacement parts become harder to find. 2. Rising Energy Bills Despite Similar Use -When Efficiency Falls Off Have you noticed a steady increase in your cooling costs? A failing compressor, refrigerant leaks, or worn-out coils can force your air conditioner to run longer and work harder, driving up your monthly bills. 3. Frequent Breakdowns and Repair Costs - The Repair vs. Replacement Math Paying for repairs every few months adds up quickly. If repair costs exceed half the price of a new system, replacement is usually the smarter choice. A new, energy-efficient unit will also cut down on future service calls. 4. Inconsistent Cooling and Hot Spots - Uneven Comfort Does one room feel freezing while another barely cools off? Inconsistent airflow often indicates that your system is struggling to maintain balanced temperatures—a sign that major components are failing. 5. Strange Noises and Unpleasant Odors - When Something Smells (or Sounds) Off Banging, grinding, or squealing noises can signal mechanical issues, while musty or burning odors may point to mold growth or electrical problems. Both are reasons to consider replacement before a safety hazard arises. 6. Refrigerant Leaks - Environmental and Performance Concerns Older units use R-22 refrigerant (Freon), which is being phased out due to environmental regulations. If your system leaks, retrofitting it can be expensive—and often less cost-effective than installing a new, eco-friendly unit. 7. Outdated Technology and Lack of Smart Features - Modern Comfort and Savings New air conditioners come with variable-speed compressors, advanced airflow designs, and smart thermostats for precise temperature control. Upgrading can offer better comfort, quieter operation, and integration with home automation systems. Seamless Replacement with Arco Heating & Cooling Replacing your air conditioner doesn’t have to be stressful. At Arco Heating & Cooling, we offer: Free in-home consultations to assess your space and recommend the right-size unit Professional removal of your old system and responsible disposal Expert installation of high-efficiency, ENERGY STAR®-rated A/C units Ongoing maintenance plans to keep your new system running at peak performance Don’t Wait Until It’s Too Late If you recognize any of these warning signs, now is the time to plan your air conditioner replacement. Avoid mid-season rushes, stay comfortable all summer, and lock in the latest energy-saving technology.

Keep Your System Running Smoothly—and Your Wallet Happy Routine HVAC maintenance isn’t just about comfort—it’s one of the smartest ways to cut costs on your energy bills and avoid expensive emergency repairs. By investing in regular tune-ups, you’ll ensure your heating and cooling system operates at peak efficiency, lasts longer, and keeps you worry-free all year long. 1. Prevent Costly Breakdowns What happens without maintenance: Dusty coils, worn belts, and loose electrical connections place extra strain on your system. Over time, minor issues can snowball into major failures that require costly parts or even a full system replacement. Your savings: A simple annual inspection can catch and fix minor wear before it turns into a breakdown—potentially saving you thousands in emergency repair bills. 2. Improve Energy Efficiency What happens without maintenance: Clogged filters or dirty coils make your system work harder, driving up energy consumption. According to industry studies, a neglected HVAC system can lose up to 20% of its original efficiency. Your savings: Clean filters and properly calibrated components can reduce your energy use by 5–15%, translating into noticeable monthly savings on your utility bills. 3. Extend Equipment Lifespan What happens without maintenance: Continuous strain speeds up wear on motors, compressors, and other key parts. A well-maintained system can often last 2–4 years longer than one that’s ignored. Your savings: Delaying a premature replacement by even a year means avoiding a $4,000–$7,000 equipment purchase—money that stays in your pocket. 4. Maintain Manufacturer Warranties What happens without maintenance: Most HVAC warranties require proof of annual professional maintenance . Skipping service visits can void your coverage, leaving you on the hook for the full cost of any repairs. Your savings: By sticking to a regular maintenance schedule, you preserve your warranty protection—ensuring that if something does go wrong, you’ll pay far less out of pocket. Discover ARCO Heating & Cooling’s Maintenance Plans At ARCO Heating & Cooling , we offer tailored maintenance plans designed to fit every budget and schedule: Silver Plan: Annual inspection, filter replacement, and priority scheduling.

Beat the Heat: Get Your A/C Ready for Extreme Temperatures When summer heat rises, your HVAC system becomes the heart of your home’s comfort. Without proper preparation, rising temps can overwhelm older or neglected systems—leading to breakdowns, higher energy bills, and discomfort. That’s why now is the perfect time to get ahead of the heat with a professional inspection from Arco Heating & Cooling . Why Preparing Your HVAC System Matters Heatwaves can put intense strain on air conditioning units, especially if they haven’t been serviced recently. A well-maintained system will: Run more efficiently Cool your home evenly Avoid mid-summer breakdowns Extend the lifespan of your equipment Tips to Prepare Your A/C for Summer 1. Schedule a Professional Inspection Annual inspections from HVAC professionals ensure your system is clean, safe, and operating at peak performance. Our Arco technicians check refrigerant levels, electrical connections, filters, coils, and more. 2. Change or Clean Air Filters Clogged filters reduce airflow and make your system work harder. Replace filters monthly during peak summer months for optimal efficiency and indoor air quality. 3. Clear the Area Around Your Outdoor Unit Remove leaves, debris, or overgrown vegetation around your condenser. This helps the unit release heat more effectively and reduces the risk of overheating. 4. Seal Leaky Ducts and Insulate Cool air can escape through poorly sealed ducts, wasting energy and making your system work harder. Consider duct sealing and insulation upgrades if you notice uneven temperatures. 5. Upgrade Your Thermostat Smart thermostats allow for programmable temperature settings, helping you stay cool while saving energy—especially during heatwaves.

Flexible Comfort for Every Room and Every Season Living in Missouri and Illinois means experiencing all four seasons—and sometimes all in the same week! From hot, humid summers to icy winters, homeowners need heating and cooling systems that can adapt to changing weather. That’s where mini-split systems shine. At Arco Heating & Cooling, we specialize in mini-split installations tailored to the unique needs of homes across the Midwest. What Is a Mini-Split System? A mini-split system is a type of ductless HVAC that provides targeted heating and cooling to individual rooms or zones in your home.

Energy Efficiency Mini-splits avoid the energy losses associated with ductwork, making them more efficient than traditional systems. Many models are ENERGY STAR® certified. 3.

How Seasonal Shifts Impact the Air You Breathe When spring turns into summer or fall shifts into winter, your home’s indoor air quality (IAQ) can change dramatically. These transitional seasons bring fluctuating temperatures, increased allergens, and different HVAC usage patterns—all of which can affect the health and comfort of your indoor environment. At Arco Heating & Cooling , we’re here to help you understand these shifts and keep your home’s air clean and comfortable year-round. What Happens to Indoor Air Quality in Transitional Seasons? More Time Indoors, More Exposure As temperatures become unpredictable, people tend to spend more time inside. While this keeps you comfortable, it also means you’re breathing indoor air more frequently—and if that air is filled with dust, pollen, or other irritants, it can take a toll on your health. Allergens Are on the Move Spring and fall are peak seasons for pollen, mold spores, and other allergens. Without proper filtration and ventilation, these particles can easily find their way indoors and linger in your HVAC system. HVAC Systems Kick Into Gear Transitional seasons often involve switching between heating and cooling. This inconsistent use of your HVAC system can lead to dust buildup in filters and ducts, impacting air quality and system efficiency. Signs of Poor Indoor Air Quality Persistent allergy symptoms Dust buildup near vents Musty or stale indoor smells Dry skin or throat irritation Excess humidity or dryness If you're experiencing any of these, it may be time to improve your indoor air quality. Arco Heating & Cooling’s Indoor Air Quality Solutions Tailored to Missouri and Illinois Homes We offer a range of products and services designed to enhance IAQ throughout transitional seasons: Air purifiers : Capture and remove airborne particles including pollen, dust, and bacteria. Humidifiers and dehumidifiers : Balance humidity levels to prevent mold growth and dry air discomfort. HEPA filters : High-efficiency filters for cleaner, healthier air. Duct cleaning services : Eliminate built-up dust, mold, and debris in your ductwork. Smart HVAC controls : Automate air quality monitoring and adjustments for convenience and efficiency.
