UV Lights and How They Can Help Your Furnace

When it comes to saving energy and staying comfortable at night, homeowners often ask: “Should I turn off my AC at night?” In this blog, we’ll break down the pros and cons so you can make the right choice for your home—and your energy bill. The Quick Answer No, you typically shouldn’t turn off your AC completely at night , especially during warm seasons . I nstead, consider turning the thermostat up a few degrees or using energy-saving features like programmable thermostats or “sleep” modes. Why People Consider Turning Off Their AC at Night There are two main reasons homeowners think about turning off their AC at night: To Save on Energy Costs: It makes sense—if the AC isn’t running, it’s not using electricity. But the actual savings might not be as big as you expect , especially if your home heats up overnight and your system has to work harder to cool it down in the morning. For Health or Comfort: Some people feel too cold while sleeping with the AC on. Others are concerned about air quality or dryness caused by constant air conditioning. Here’s What Really Happens If You Turn It Off Turning off your air conditioner completely can lead to: Increased Humidity: Without your AC running, humidity levels in your home can rise , making it feel warmer and less comfortable. Disrupted Sleep: Studies show people sleep better in cooler temperatures (around 60-67°F). Turning off your AC might make it harder to fall or stay asleep. Overworking Your AC Later: If your home heats up overnight, your system will need to work harder in the morning to bring the temperature back down, which could cancel out any energy savings. Better Alternatives to Turning Off Your AC at Night Instead of shutting it down completely, here are a few smarter ways to stay cool and save money: Use a Programmable or Smart Thermostat Set your thermostat to increase the temperature by 2–4°F at night . You likely won’t notice a big change in comfort, but you will see a difference on your energy bill. Turn on ‘Sleep’ or Eco Modes Many modern AC units have energy-saving features that automatically adjust cooling at night to maintain comfort with less energy use. Improve Home Insulation A well-insulated home retains cool air longer , meaning your AC doesn’t have to run as often—even during the night. Use Fans to Circulate Air A ceiling or box fan can help circulate cool air and make your bedroom feel more comfortable without lowering the thermostat. The Bottom Line Turning off your AC at nigh t isn’t usually the best move . Instead, adjust the temperature settings, use fans, and rely on smart technology to strike the perfect balance between comfort and energy efficiency.

Imagine living through a scorching summer without any relief from the heat. For most of human history, that was reality. But thanks to a revolutionary invention— air conditioning —our modern lives have become significantly more comfortable, productive, and even safer. The history of AC is more than just a story of cool air; it’s a story of how technology reshaped the way we live, work, and build our cities. The Origins of Cooling Long before mechanical systems existed, ancient civilizations sought creative ways to stay cool. Egyptians used wet reeds in windows to cool incoming breezes. The Romans circulated aqueduct water through walls. In 2nd century China, inventor Ding Huan created a manually powered rotary fan. But none of these methods offered consistent or large-scale relief from heat. The real turning point came in the early 20th century with the birth of modern air conditioning. Willis Carrier and the Birth of Modern AC In 1902, Willis Haviland Carrier , a young engineer, invented the first electrical air conditioning system—not for comfort, but to solve a humidity problem at a printing plant in Brooklyn, New York. The high humidity was causing the paper to warp and the ink to misalign. Carrier’s system controlled both temperature and humidity, dramatically improving printing quality. His invention worked by blowing air over cold coils, cooling and dehumidifying the air —an early version of what we still use today. Carrier went on to found the Carrier Engineering Corporation in 1915 , laying the foundation for a new industry. From Factories to Theaters to Homes Initially, air conditioning was used mainly in industrial settings to improve manufacturing conditions—for example, in textile mills and pharmaceutical labs. But by the 1920s , the technology began to spread to public spaces. Movie theaters were among the first to adopt AC for comfort. In the 1920s and 30s, theaters advertised “ refrigerated air ” to draw in summer crowds. The success was immediate. For many people, the local movie theater became their first experience with cool indoor air during hot summers. By the 1950s , residential air conditioning started to take off, particularly in the United States. As window units became more affordable and central systems more efficient, AC transformed from a luxury to a standard feature in many homes. AC’s Global Impact The widespread adoption of air conditioning has had a profound impact on society: 1. Urban Development and Population Growth Air conditioning enabled large-scale development in hot and humid regions. Cities like Houston, Dubai, Singapore, and Phoenix saw explosive growth, much of it made possible because indoor spaces could be made livable year-round. 2. Economic Productivity By regulating indoor temperatures, AC has increased productivity in workplaces, improved conditions in data centers, and allowed for longer operating hours in retail and service industries. 3. Health and Safety AC has reduced heat-related illnesses and deaths, particularly among vulnerable populations. It also supports hospitals, food storage, and laboratories —key infrastructure for public health. 4. Cultural Shifts AC influenced architecture (goodbye, high ceilings and cross-ventilation), led to changes in building design (more sealed glass towers), and even reshaped how people spend their time—indoors, in climate-controlled environments . More Than Just Cool Air Air conditioning has done more than keep us cool. It has transformed economies, reshaped cities, improved public health , and changed our daily lives. As we look ahead, the next chapter in AC’s story will be about making cooling accessible, efficient, and climate-friendly. From the printing press in 1902 to skyscrapers in Dubai, the journey of AC is a powerful example of how a single invention can reshape the world. Innovations are on the rise. Advances in green building design, solar-powered AC , more efficient heat pumps , and new refrigerants are making sustainable cooling more attainable. Call us at (720)-737-6311

As temperatures climb, air conditioning quickly becomes a necessity—not a luxury. But if you’re noticing skyrocketing energy bills every summer, your AC system could be the main culprit. At FerguSon's Heating & cooling, we believe in keeping you cool without burning through your savings. Let’s break down why your current AC might be costing you more than it should—and what you can do about it. The True Cost of Running an Old AC Unit Air conditioners , especially older models, are notorious energy hogs. Units that are 10–15 years old often operate at half the efficiency of modern systems. That means: Higher energy bills month after month Frequent repair costs Poor cooling performance , especially during heatwaves More strain on your home’s electrical system If your unit is over a decade old, it could be using up to twice the electricity of today’s high-efficiency models. Why AC Bills Get Out of Control There are a few key reasons your AC bills might be rising faster than the temperature: Low SEER Rating – Seasonal Energy Efficiency Ratio (SEER) measures how efficiently your AC runs. Older units have ratings as low as 8–10 SEER . Today’s systems are required to have at least 14–15 SEER, with high-efficiency options reaching 20+ . Poor Maintenance – Dirty filters, clogged coils, and refrigerant leaks can all reduce efficiency. Wrong Size Unit – An AC that’s too small runs constantly, while one that’s too big cycles on and off, wasting energy both ways. Outdated Thermostats – Manual thermostats or basic digital models can’t optimize energy use the way smart thermostats can. Cost-Effective Ways to Lower Your AC Bills Before you suffer through another expensive summer, consider these energy-saving tips: Upgrade to a High-Efficiency System Replacing your outdated unit with a modern, energy-efficient air conditioner can slash your energy bills by up to 40% . Plus, with manufacturer rebates and energy incentives, the upfront cost may be lower than you think. Install a Smart Thermostat Smart thermostats learn your schedule and adjust cooling accordingly, saving energy when you’re not home and keeping you comfortable when you are. Schedule Regular Maintenance A well-maintained system runs more efficiently. Our affordable service plans keep your system in peak condition all year round. Seal and Insulate Proper insulation and sealing air leaks prevent cool air from escaping, reducing the load on your AC. Use Ceiling Fans They help circulate air more effectively, allowing you to raise your thermostat by a few degrees without sacrificing comfort. Let’s Talk Numbers Think your old AC is “good enough”? It could be costing you hundreds—if not thousands —more than necessary over its remaining lifespan. Let’s run the numbers together . We offer free in-home consultations to show you how much you could save by upgrading. We’ll help you: Choose the right system size for your home Understand available rebates and financing options Remove your old unit and install your new system quickly and cleanly Set up smart thermostat controls for optimal savings Call us at (720)-737-6311

Is your AC unit frozen? A frozen air conditioner is one of the most common — and frustrating — HVAC problems homeowners face, especially during peak summer heat. You might notice ice on the evaporator coils , poor airflow , or your AC just blowing warm air . The good news? A f rozen AC doesn’t always mean major repairs . But acting quickly is key. As your trusted local HVAC company, we’ve put together this step-by-step guide to help you respond safely and effectively when your air conditioner freezes. Step 1: Turn Off Your AC Immediately The first thing you should do is turn off your air conditioner at the thermostat. Continuing to run it while frozen can: Damage the compressor Waste energy Make the problem worse Set your system to “OFF” and switch the fan to “ON” to help thaw the ice faster. Step 2: Check for Airflow Blockages Poor airflow is one of the top causes of a frozen AC unit. Once your system is off, check for these common airflow issues: ✅ Dirty air filter — Replace it if it’s clogged ✅ Closed or blocked vents — Make sure all supply and return vents are open and unobstructed ✅ Dirty evaporator coil — Excess dust can insulate the coil and cause freezing Pro Tip: If your filter looks like it hasn’t been changed in a while, that could be the culprit. Step 3: Let the Ice Melt Completely Depending on how frozen your AC is, it can take a few hours up to a full day for the ice to thaw. ⚠️ Do not chip away at the ice! This can damage the coils and void your warranty. Speed up the process by: Running the fan only (if safe) Opening nearby windows to improve air circulation Using a box fan to help circulate air near the indoor unit Step 4: Inspect Your Condensate Drain Line While your system is thawing, check the drain pan and condensate line for clogs or standing water . If the line is blocked, it can cause water to back up and freeze around the coil. Signs of a clogged line include: Water around the indoor unit A musty smell Frequent shutdowns Step 5: Schedule a Professional HVAC Inspection A frozen AC can be a sign of underlying issues , including: Low refrigerant levels Blower motor problems Dirty or damaged coils Ductwork restrictions Thermostat malfunctions Our certified technicians can diagnose the root cause and get your AC running efficiently again — before it becomes a more expensive repair.

1. Environmental Impact A2L refrigerants are l ow-GWP refrigerants , meaning they have a drastically reduced potential to contribute to global warming compared to traditional refrigerants like R-410A. R-410A has a GWP of 2,088 . R-32 has a GWP of 675 . R-454B has an even lower GWP of 466 . This makes A2Ls a c limate-conscious choice that supports global and national efforts to reduce greenhouse gas emissions. As part of the HFC phasedown under the AIM Act , these refrigerants are a forward-looking solution aligned with environmental regulations. 2. Energy Efficiency = Lower Utility Bills A2L refrigerants, particularly R-32 , are known for their superior thermodynamic efficiency , which means HVAC systems using them often consume less energy to cool or heat your home. R-32 is around 10% more efficient than R-410A. Systems using A2Ls often have higher SEER2 ratings (Seasonal Energy Efficiency Ratio). This i ncreased efficiency translates to: Lower monthly energy bills Reduced wear and tear on your HVAC components Less energy waste , benefiting both your wallet and the planet
