Winter in Southwest Virginia brings a distinct chill to the air. As temperatures drop across Lebanon and the surrounding region, homeowners inevitably watch their heating systems turn on more frequently. This reliable comfort comes at a price, and for many, the arrival of the first high utility bill of the season is an unwelcome jolt. Heating and cooling often account for the largest portion of a home’s energy budget. Skyrocketing energy costs combined with an inefficient system can place a significant strain on household finances. The good news is that you are not powerless against rising expenses. You can take control of your home’s energy consumption. Achieving significant savings is not about finding one single magic solution; it is about implementing a layered strategy. This strategy combines simple daily habits, essential DIY maintenance, and smart long term investments in your home’s efficiency.
Master Your Thermostat for Immediate Savings
The single most effective tool for managing heating costs is already on your wall. Your thermostat is the command center for your entire heating system, yet it is frequently misused. The most common mistake is setting the temperature too high and leaving it there all day and night. Every degree you raise the heat significantly increases fuel consumption. Many homeowners find themselves in a battle over the thermostat, pushing it up when they feel a chill, only to find the home uncomfortably warm later. This “set it and forget it” approach at a high temperature is the fastest way to waste energy and money.
Finding a balance between comfort and efficiency is key. Energy experts often recommend a baseline of 68 degrees Fahrenheit while you are home and awake. This provides a comfortable living environment without overworking your furnace or heat pump. The real savings, however, come from setbacks. A setback is a period when you intentionally lower the temperature. You can save up to ten percent on your heating bill by turning your thermostat back 7 to 10 degrees for eight hours a day. The easiest times to do this are when you are away at work or at night while you are asleep under warm blankets.
A programmable thermostat automates this process. Instead of manually adjusting the temperature multiple times a day, you can create a schedule that matches your family’s routine. You can set it to lower the heat 30 minutes before you leave for work and to begin warming the house 30 minutes before you return. This ensures you never waste energy heating an empty home but always return to a comfortable space. This automation removes the guesswork and ensures you capture those savings every single day.
Smart thermostats represent the next evolution in home climate control. These devices connect to your home’s Wi Fi and learn your household’s patterns over time. They can detect when no one is home and automatically adjust to an energy saving setting. You can also control them remotely from a smartphone, allowing you to make adjustments if your schedule changes. Many smart thermostats also provide detailed energy reports, showing you exactly how much energy you are using and when. This data empowers you to find even more opportunities to save.
For larger or multi story homes, a zoning system can offer substantial savings. Zoning divides your home into different areas, each controlled by its own thermostat. This allows you to heat the main living areas during the day while keeping guest rooms or an unused basement at a much lower temperature. It stops you from paying to heat rooms you rarely enter, focusing your energy spending only where it is needed.
Address Drafts and Air Leaks
Your heating system works hard to produce warm air. Unfortunately, in many homes, a significant portion of that expensive warm air escapes through countless small cracks and gaps. This process, known as air infiltration, forces your system to run longer and harder to maintain the temperature you have set. Cold air from outside seeps in, while warm air seeps out. Finding and sealing these leaks is one of the most cost effective ways to improve your home’s comfort and reduce your energy bills.
The most obvious culprits are windows and doors. Check the weatherstripping around all exterior doors. If it is cracked, compressed, or missing, it needs to be replaced. You can test the seal by closing a door on a dollar bill; if you can pull the bill out easily, the seal is not tight enough. Similarly, check the caulking around window frames, both inside and out. Over time, caulk can dry out, shrink, and crack, creating a direct path for air. A simple tube of caulk and a few hours of work can seal these gaps effectively.
Air leaks also hide in less obvious places. Cold air can travel through the walls and enter your living space through electrical outlets and switch plates on exterior walls. You can easily stop this by installing inexpensive foam gaskets behind the cover plates. Plumbing penetrations under sinks and behind appliances are another common source of drafts. These gaps, where pipes enter your home, should be sealed with expanding foam or caulking. Do not overlook the attic hatch or pull down stairs. This opening is often poorly sealed and acts like a massive hole in your ceiling, allowing warm air to rush into the cold attic. Applying weatherstripping to the perimeter of the hatch can solve this problem.
Fireplaces are another major source of heat loss. When not in use, a fireplace damper should always be kept closed. An open damper is like leaving a window open, allowing warm air to escape up the chimney. Even a closed damper may not seal perfectly. If you rarely use your fireplace, consider a chimney balloon or draft stopper to seal it off more securely. Glass fireplace doors can also help reduce heat loss.
If you have sealed the obvious spots and still feel drafts, you may benefit from a professional energy audit. A technician can perform a blower door test, which depressurizes your home to make it easy to find even the most well hidden leaks. This diagnostic test provides a clear roadmap for improving your home’s airtightness, ensuring your heating efforts are not going to waste.
Optimize Your Insulation
Insulation is the thermal barrier that keeps your home warm in the winter and cool in the summer. It works by resisting the flow of heat. The effectiveness of insulation is measured in R-value; a higher R-value means better insulating performance. Without adequate insulation, the heat your furnace generates will pass directly through your ceilings and walls, escaping to the outside. This forces your system to run almost continuously just to keep up.
The most critical area to insulate in any home is the attic. Heat naturally rises, and in an under insulated home, the attic is the primary exit point. Many older homes in Virginia are severely lacking in attic insulation by modern standards. You can often do a quick visual check. If you can easily see the tops of your ceiling joists, you almost certainly need more insulation. For our climate zone, ENERGY STAR recommends an attic insulation level of R49 to R60. This often translates to 16 to 22 inches of blown in or fiberglass insulation. Adding insulation to your attic is a project that can pay for itself in just a few years through lower utility bills.
While the attic is the top priority, other areas of your home are also important. Exterior walls should be properly insulated, though this is more difficult to retrofit. Basements and crawl spaces are another major source of heat loss. Insulating the walls of a conditioned basement or the ceiling of an unconditioned crawl space can make a noticeable difference in the comfort of the floors above and in your overall energy consumption. Pay special attention to the rim joist, which is the wooden perimeter of your home that rests on the foundation. This area is often completely uninsulated and allows a tremendous amount of cold air to enter.
There are several types of insulation, including fiberglass batts, blown in cellulose, and spray foam. Each has its own benefits. Fiberglass batts are common for new construction or open walls. Blown in cellulose or fiberglass is excellent for adding insulation to existing attics because it fills in gaps and settles around obstructions. Spray foam offers the highest R-value per inch and creates an air seal, but it is also the most expensive option. Upgrading your insulation is a significant investment, but it provides returns every single day for as long as you live in your home.
Maintain Your Heating System
Your home’s HVAC system is a complex machine. Just like a car, it requires regular maintenance to operate safely, reliably, and efficiently. A neglected system will work harder, use more fuel, and be more likely to break down on the coldest day of the year. Investing in routine maintenance is not an expense; it is a crucial step in protecting your system and saving money.
The single most important task a homeowner can perform is to regularly check and change the air filter. A dirty, clogged filter is your heating system’s worst enemy. It chokes the system, restricting the flow of air. This forces the blower motor to work harder and run longer, consuming more electricity. It can also cause the furnace’s heat exchanger to overheat, which can lead to a system shutdown or even a cracked heat exchanger, a serious safety hazard. Depending on your system and home, you should check your filter monthly and replace it at least every three months.
You should also perform a quick visual inspection of your home. Walk around and ensure that all your heating registers and return air vents are open and unblocked. Furniture, rugs, and curtains can obstruct airflow. This blockage can create pressure imbalances in your system and prevent warm air from circulating properly, leading to cold spots and making your furnace run longer to heat the entire house.
While these DIY steps are vital, they cannot replace a professional tune up. An annual maintenance visit from a qualified HVAC technician is essential. During a tune up, a technician performs a comprehensive inspection and cleaning. They will clean and adjust the furnace burners to ensure clean and efficient combustion. They will inspect the heat exchanger for any signs of wear or cracks. They will check all electrical connections, test safety controls, and lubricate moving parts like the blower motor to reduce friction and electricity use.
This professional service does more than just save money on energy. It is a critical safety check. A technician can spot potential problems, such as a small gas leak or a carbon monoxide issue, before they become dangerous. A well maintained system is also a reliable system. The cost of a tune up is minimal compared to the expense and inconvenience of an emergency breakdown in the middle of winter. A clean, efficient system uses less fuel to produce the same amount of heat, directly lowering your monthly bills.
Harness the Power of Your Home’s Environment
Not all energy saving measures require an invoice or a service call. You can make a surprising impact on your heating costs by simply using your home’s natural environment to your advantage. These strategies are simple, free, and can be implemented immediately.
Take advantage of the sun. The sun is a powerful, free source of heat. On bright, sunny days, open the curtains and blinds on all your south facing windows. This allows passive solar gain to warm your home naturally, giving your heating system a much needed break. This simple act can raise the temperature in a room by several degrees.
Conversely, as soon as the sun goes down, close those same curtains and blinds. Windows are a major source of heat loss, even modern double pane windows. Heavy curtains or cellular shades act as an extra layer of insulation, trapping a layer of air between the fabric and the cold glass. This simple habit reduces the amount of heat that escapes your home at night.
Another often overlooked tool is your ceiling fan. Most people associate fans with cooling, but they are incredibly useful in the winter. Heat rises, which means the warmest air in your home collects near the ceiling, where it does you no good. Most ceiling fans have a reverse switch. In the winter, you want the blades to rotate clockwise on a low speed. This gentle updraft pushes the warm air trapped at the ceiling down the walls and back into the living space, helping to distribute heat more evenly. This can make you feel warmer, allowing you to lower your thermostat by a degree or two.
Finally, consider the humidity level in your home. Winter air is notoriously dry. That dry air makes your skin feel itchy and can even damage wooden furniture. It also makes you feel colder than you actually are. Moist air holds heat better than dry air. By using a whole home or portable humidifier to maintain an indoor humidity level between 30 and 50 percent, you will feel more comfortable at a lower thermostat setting. This means you can turn down the heat without sacrificing comfort.
Consider Long Term System Upgrades
There comes a point where maintenance and DIY tips can no longer overcome the inefficiency of an old, outdated heating system. If your furnace or heat pump is more than 15 years old, it is likely operating far below modern efficiency standards. Continuing to repair an aging system can be a poor investment. The money spent on frequent repairs, combined with high monthly energy bills, could be put toward a new, high efficiency unit that provides long term savings.
When evaluating a new furnace, the most important metric is the Annual Fuel Utilization Efficiency, or AFUE rating. This number represents how much of the fuel consumed is converted directly into heat for your home. An old furnace from the 1990s might have an AFUE rating of 80% or even lower. This means 20 cents or more of every dollar you spend on fuel is wasted. Modern high efficiency furnaces, by contrast, can have AFUE ratings of 95% or higher. This dramatic increase in efficiency translates directly into lower monthly heating bills.

For the Southwest Virginia climate, a heat pump is an excellent and highly efficient option. A furnace creates heat by burning fuel, while a heat pump works by moving heat. In the winter, it extracts heat from the outside air, even on cold days, and transfers it inside. Because it is moving heat instead of creating it, it can be incredibly efficient. Many homeowners in our region opt for a dual fuel system. This pairs an electric heat pump with a gas furnace. The system uses the hyper efficient heat pump for most of the winter. Then, if the temperature drops to an extreme low, it automatically switches over to the gas furnace for powerful backup heating.
You must also consider your ductwork. Your ducts are the circulatory system that delivers warm air. In many homes, this ductwork is leaky, poorly sealed, or uninsulated. If your ducts run through unconditioned spaces like a crawl space or attic, you could be losing 20 to 30 percent of your heated air before it ever reaches your rooms. This is a massive waste of energy. Sealing those ducts with mastic and insulating them can be one of the most impactful upgrades you can make. A properly sealed and insulated duct system ensures all the heat your system produces gets delivered where you need it, improving comfort and slashing energy waste.
Saving money on heating is a multifaceted approach. It begins with simple, no cost actions like managing your thermostat and using your curtains effectively. It builds with proactive DIY tasks like sealing drafts and changing filters. These steps are then supported by professional maintenance, which keeps your system running safely and efficiently. Finally, long term planning for upgrades to insulation or a new high efficiency system can secure your comfort and savings for decades to come. By layering these strategies, homeowners in Lebanon can fight back against rising energy costs, reduce their environmental impact, and ensure their home remains a warm, comfortable refuge all winter long.
