What to Know Before Buying a Whole House Generator in Sterling, VA

No matter where you live, owning a whole house generator has become a must-have during power outages, especially during extreme weather conditions. It is not uncommon for the weather to cause power outages, especially in Sterling, VA, where storms can cause property damage and other disasters that can interrupt your daily life. In such situations, having a whole house generator ensures that your household and your loved ones remain safe and comfortable. Here is everything you need to know before purchasing a whole house generator for your home in Sterling, VA.

Power Requirements

One of the most crucial factors to consider when selecting a whole house generator is the power requirements for your home in Sterling, VA. Before buying a generator, it is essential to determine your home’s power consumption. Start by listing all the essential items that need power, such as lights, refrigerators, heaters, and other home appliances. You will also want to factor in your home’s air conditioning, water pumps, sump pumps, and other vital power systems. Once you know the total power consumption of your home, you can choose a generator that matches or exceeds that output.

Size of the Generator

Another essential factor to consider when choosing a whole house generator is the size. A generator that is too small for your Sterling, VA home may not be able to manage your power requirements during power outages, while a generator that is too large may result in higher fuel costs. The size of the generator you need depends on your home’s power requirements. Before making a purchase, consult a professional generator installation expert.

Fuel Type

Next, you want to consider the fuel type for your whole house generator. There are several types of fuels you can choose from, including propane, diesel, and natural gas. Each fuel type has its benefits and drawbacks. For example, propane burns cleaner and has a more extended shelf life than diesel. Natural gas, on the other hand, is more affordable and widely available in Sterling, VA.


Regular maintenance is required for any generator to work optimally. However, some generators require more maintenance than others. Before making a purchase, research the maintenance requirements for the generator you are considering. Some require monthly maintenance, while others need to be serviced once a year. Make sure to choose a generator that is easy to maintain.


The cost of a whole house generator can vary, depending on its size, fuel type, and other features. When selecting a generator for your Sterling, VA home, it is important to balance cost and functionality. While you may be tempted to save money by buying a cheap generator, this might not be the best choice overall. A high-quality generator will last for years and provide you with reliable power during outages.


When it comes to buying a whole house generator in Sterling, VA, there are several factors you need to consider before making a purchase. These include calculating your home’s power requirements, choosing the right size and fuel type, researching maintenance requirements, and balancing cost and functionality.
