How to Prepare Your HVAC for Winter

CMG • September 5, 2022

As the seasons change, so do the demands placed on your HVAC system. The cold winter months ahead may allow you to stash away your air conditioner and save on cooling costs, but those savings will be offset by the time and energy spent running your home's furnace.


With so much change taking place across your HVAC system's operations, it's important to perform seasonal HVAC maintenance that will prepare both your air conditioner and furnace for the months ahead. From making sure you winterize your A/C unit to testing your furnace to make sure it's ready for a heavy winter workload, read on for some winter HVAC service tips to maximize performance and minimize heating and cooling costs.

Schedule Your Air Conditioner's Seasonal Maintenance

Many homeowners question the importance of servicing their air conditioner in the fall, right before the appliance is packed away for the winter months. But while seasonal maintenance for your air conditioner is crucial in the spring, fall maintenance can also impact the health of your air conditioner, the risk of intensive maintenance and repairs come the spring, and the overall lifespan of the appliance.


Fall A/C service can clean out leaves and other debris that accumulate over the summer, and it can reduce the risk of rusting and other material breakdowns that can accelerate aging in the appliance. Once spring rolls around, you can schedule another tuneup to make sure the unit is ready to resume its heavy summer workload.

How to Winterize Your HVAC System

Wondering what tasks need to be taken care of during your HVAC's fall service? While an HVAC technician can evaluate your system's unique needs and make sure it's ready for the long winter ahead, any process to winterize your HVAC system should include the following steps:


  • Schedule a tuneup for your furnace. A tuneup from an HVAC technician will handle all of the technical maintenance needs that will help your furnace remain up-and-running throughout the winter. Tuneups can clean debris from your furnace, tighten and lubricate internal components, and address small issues before they cause costly appliance breakdowns.
  • Change furnace filters. Most furnace filters need to be changed every 90 days, if not sooner. HVAC experts recommend starting the fall season with a fresh filter to clean your home's air.
  • Check your furnace's pilot light. If your furnace runs on gas and the pilot isn't lit, you won't be getting any heat when the appliance turns on.
  • Disconnect and cover your air conditioner. If your home has a freestanding air conditioner, disconnect it from electricity and place an A/C cover over the unit to protect it from the elements this winter.
  • Check the batteries in your carbon monoxide detector. Faulty furnaces could release deadly carbon monoxide into your home. A carbon monoxide detector is essential to keep you and everyone in your home safe from an accidental poisoning.

Other Tips to Improve HVAC Performance in Winter

Along with a tuneup and maintenance to both your furnace and A/C unit, every household can take some simple steps to alleviate the burden of keeping their home heated during the winter. While not directly related to the functioning of your furnace or air conditioning unit, the following steps will improve HVAC performance and save you money on heating this winter:


  • Add insulation in your attic. Increased insulation will reduce heat loss through one of the most vulnerable parts of your home. An insulation expert can inspect your attic's existing insulation and determine whether an added layer could lower heating costs for your home this winter.
  • Reseal cracks around your doors and windows. Cracks in your home's caulking, or in weather-stripping, can create drafts that accelerate heat loss and increase your furnace's runtime.
  • Install a smart thermometer. Smart thermometers offer a number of benefits when managing both your furnace and air conditioner operations. Eco-friendly heating and cooling, as well as programmable features to optimize when and how you heat and cool your home, can lower heating and cooling costs while also improving HVAC efficiency.
  • Turn down your indoor air temperature. Lower heating demands reduce the burden placed on your HVAC in winter. Even a few degrees can drastically reduce the run time for your furnace, extending the life of this appliance and saving you money on your monthly utilities bill.
  • Clean your air ducts. Dust, pet dander and other debris can build up in your home's ventilation, reducing indoor air quality while also putting your HVAC system health at risk.


Negligent HVAC maintenance won't save you money—it will only delay the cost of tending to your furnace and A/C unit, while also increasing the long-term repair needs for these appliances. With temperatures in decline, take this seasonal opportunity to tune up your HVAC system and enter the winter with greater peace of mind.

The History Of Plumbing
May 17, 2023
Plumbing is integral to our everyday lives, providing us with essential water supply and sanitation systems. It ensures our homes and buildings have clean water for drinking, bathing, and other domestic needs. However, have you ever wondered about the origins of this vital system? For instance, when was plumbing invented? Well, plumbing has a long history. The greatest ancient civilizations like Greek, Roman, Persian, Indian, and Chinese have used the first versions of plumbing. While in the modern era, plumbing includes advanced features that keep your home hygienic and free of disease and contamination, plumbing in the ancient period meant having usable water inside and a way of removing wastewater. Let’s discover the answers to these fascinating questions about plumbing history, including - when did indoor plumbing start, who invented indoor plumbing, when did indoor toilets become common in America and all the exciting bits. Plumbing's Origin in Ancient Era In Mesopotamia, the elite class residents used separate bathrooms and indoor toilets to discard the waste into the river in 3000 BCE. Around 2600–1800 BCE, some regions, including Harappa, Rakhigarhi, and Mohenjo-Daro, developed the first urban sanitation systems in ancient India. These civilizations used well water through masonry conduits and dumped wastewater into the street drains. Around 2500 BCE, Egyptians started to use copper pipes to create complex plumbing and drainage system. The first version of flushing toilets was stone seats placed over water streams where a bucket of water was used to do the flushing. Around 2000 to 1700 BCE, these toiles were discovered in the Mediterranean island of Crete. The ancient Greek island of Crete created an advanced drainage system around 1700 to 1500 BCE. Their design included terracotta pipes and joint sockets. However, the ancient Romans made significant advancements in plumbing technology. Around 510 to 31 BCE, they started to use fresh water in baths, fountains, and toilets that came through tunnels of pipes. Romans built aqueducts to transport fresh water from the countryside to Rome. The water was collected in tanks to distribute. But, around 200 BCE, Romans replaced their existing system with lead pipes which caused countless deaths from lead poisoning. Plumbing in the Early Modern Era The invention of the flush toilet is attributed to Sir John Harington - Queen Elizabeth I's godson - an English courtier in the late 16th century. Long after, in 1652, America's Boston City built a water system for domestic and fire-fighting purposes, where pipes were made of tree logs. In 1664 a cast-iron water main was built in France's Marly-on-Seine to the palace at Versailles. This main could reach up to 15 miles from the pumping station, which supplied water to the palace gardens, fountains, and nearby towns. Then, in 1767, William Feetham designed the world's first mechanical shower. At that time, hot baths were popular, and no one wanted this cold and dirty water for a bath. However, this shower offered recycled water to be used in the shower. Alexander Cumming patented a toilet similar to the first flushing toilet but with improved features in 1775. This toilet had a flush mechanism that let users employ and refill the pan. It also prevented the sewer gas from entering the bathroom. This invention laid the foundation for the modern indoor toilets we use today. In 1778, Joseph Bramah patented a new toilet design which was an improved version of Cumming's design. And in 1795, New York built a unique water system for the firefighters. It was a network of logs that supplied water throughout the city. Firefighters drilled the logs and plugged the hole to access water. Now let’s take a look: Plumbing in The Modern Era During 1815 Philadelphia started supplying water governed by the municipality. They built a dam and water wheels across the Schuylkill River to provide water directly to businesses and homes through pipes. By 1819 cast iron mains began to replace the wooden system in Philadelphia. The Tremont Hotel of Boston installed indoor plumbing for guests in 1829, including indoor toilets and running water. Later in 1833 White House installed a plumbing system on the main floor of the presidential home. In the 1800s, Midtown Manhattan constructed its first reservoir in 1835, sourcing water from the Croton River. By 1842, the reservoir was operational, supplying approximately 72 million gallons of water daily. Later in 1855, America established its first sewer system, while in 1870, Thomas William Twyford introduced the ceramic flushing toilets. In the late 19th century, Thomas Crapper revolutionized the flushing toilet by introducing a floating ballcock and a "U" shape trap around 1880. This innovation improved the efficiency and reliability of toilets, setting the foundation for modern plumbing systems.
