Have you ever thought about what you’d be doing in the event of a power failure at home?
Sure, it’s easy to wait for a couple of minutes hoping for electricity to be back– but what if it goes on for an extended period? Picture this: your home in total darkness for hours, or maybe even days. No appliances, no light, no electronics– power outages can be a very uncomfortable (and borderline traumatic) experience for many homeowners. It would be twice as agonizing during severe weather storms or in the event of natural disasters.
With that in mind, it’s crucial to have an alternate power source at home. A whole house generator can make your household emergency-proof, as these machines are automatically switched on once the power goes out.
But what will it cost?
You can expect a whole-house generator to cost about $4,350 on average. Such is the price tag you need to make to provide backup power to the entire house.
A more general estimate for medium-sized homes is at $12,500 to $27,300 upfront. The total costs will have an additional $185 to $500 in annual generator maintenance and upkeep. Although the costs may appear expensive to several homeowners, more families realize the benefits of having a whole house generator at home. If you live in an area with frequent outages and severe weather conditions, it’s a necessary machine to ensure your comfort 24/7.
Given that one unit may go up into the tens of thousands, many homeowners remain unsure if it is truly an excellent investment to make. Generators also range in type, size, and function– so the choice can get confusing.
Fret not, we’re here to discuss everything about whole house generator costs, and we’ll cover some essential points you need to know. This guide will help you determine the right generator for your home power backup needs.
Why Buy a Whole House Generator?
A whole house generator is connected to your home’s electrical wiring system. As soon as it detects a power outage, it will provide your household with sufficient backup power, at least until the electricity comes back. Though it sounds like one essential machine at home– it can be rather expensive at a thousand dollars minimum. There are also other maintenance costs in keeping a whole house generator at home.
The installation of a whole house generator also needs to be left to a professional generator technician. These specialists can closely monitor your generator units, such as oil or filter changing and other routine upkeep services. Doing so will extend the lifespan of your whole house generator.
In case you’re wondering if it will be a good investment– Remodeling Magazine reported that your property would get an average of 150% Return on Investment (ROI) after installing a whole house generator. For example, a generator worth $15,000 will add $9,000 more value to your home. So consider it an excellent long-term investment for your property.
Generators: Cost Per Scale
The big question goes, what kind of generator can I buy on my budget? That depends on several factors, including brand, fuel source, size, and generator type.
Regardless, there will be an ideal generator to meet all your backup power needs. So, let’s take a closer look at the options you can expect at different price points.
Some units have a power capacity of up to 40 KW, allowing you to use multiple appliances in almost the same manner you use standard electricity. So you might not even notice there’s a power outage going on.
Factors Affecting Whole House Generator Cost
Keep in mind that there will be several factors that can either increase or decrease your whole house generator expenses. No one prize fits all as your home’s generator needs will be unique.
For your reference, let’s discuss the factors in detail.
Cost of Generator
In selecting a whole house generator, you will need to consider the upfront costs of the generator unit itself. You will also choose from two primary generator types: portable or standby.
Another determining factor on the price of your whole house generator is its power capacity or wattage. It would be best to determine the answers to questions such as, how much power you need for your essential appliances? The unit’s kilowatts (kW) capacity will heavily influence the cost of your whole home generator.
Popular generator sizes for home use are available in different varieties, such as 11, 16, and 20 kW generator units. If you’re uncertain about the ideal generator capacity for your home’s power needs, talk to an electrician to avoid wasting money in buying the wrong generator.
Portable generators are an efficient choice for homeowners wanting to save some money as they do not have recurring heavy maintenance costs. Since you can move them anywhere around your house, they will be more durable and easier to operate.
Meanwhile, a standby generator will generally cost you more. In addition, you will need the services of an electrician to have your unit installed correctly into the electrical panels and its fuel source. Expect additional fees for local permits and necessary site preparation as well. Aside from the two main generator types (portable and standby), inverter units are becoming another popular generator type for residential use. These generators work similar to portable generators– but they are connected to an inverter instead. As a result, the system takes in DC only to change it back to AC.
This choice is great for homeowners looking for energy-efficient solutions, as the generator provides clean energy. Some units also come in a portable design for that added convenience.
Opting for a standby generator will cost you around $4,560 on average, including assembly-relevant permits and wiring work.
In some cases, you may need to dig a tank for your generator unit. Some areas may require a special permit for tank digging and installation– which may add to the total tab. Electrical lines may also need to be extended for your generator to run efficiently. Accordingly, your installation costs will be higher if your home is far away from fuel lines to ensure having safe ventilation and exhaust ducts.
Another defining factor that may affect your whole house generator installation costs includes nearby access to natural gas lines. If you live in an area without underground pipes, you will have to go with generators running on liquid propane.
Your generator’s fuel source may also influence your whole house generator expenses. These units need a consistent supply of fuel to provide power. If you have a portable generator, you will commonly need diesel, liquid propane, or gas as a fuel source. In contrast, standby generators are permanently installed– so it needs a dedicated natural gas line or a propane tank.
Most homeowners choose their go-to fuel source depending on their intended budget and preference. Here are some of the most popular fuel types for generators:
The larger your preferred generator is, the more circuits you’ll need to have it wired on. Small-sized generators can work with only several circuits, so installing a large generator will cost you more as it will need more work. Keep in mind that the size of generators is measured in kilowatts (kW). It will be the measurement of how powerful your unit will be.
If your chosen generator unit has a higher kW, you can expect more standby power in the event of a random blackout. Generators for home use begin at 5 to more than 50 kW in size. However, these machines typically come at a cost. Consult an electrician to determine your home’s ideal generator size. They will calculate the electric load of all the appliances you want to run amid a power outage– ensuring that your generator unit will have sufficient power.
Some relevant data that your electrician will calculate are as follows:
Once the data listed above have been measured precisely by your electrician, you can now make an informed decision regarding the right size of your whole-house generator.
Location of Generator
Several homeowners remain uncertain about the proper placement of their generators. A great rule of thumb to follow would be placing your unit near the electric meter. However, if you want to go with a natural gas generator route, have it somewhere between the electric meter and the gas meter. The decision will also greatly depend on your home’s layout and any local safety requirements in your area.
Technically, the installation will cost you more if your generator is located far away from the electric or gas meter lines. It would require more labor on your contractors, as they will have to run necessary wires from your unit to the meters. Also, some whole house generators will require some foundation (concrete or gravel) for support. The construction of this will only add to your installation expenses, ranging from $70 to $90 per square foot for preparing the site and pouring the concrete.
The best way to determine the perfect placement of your whole house generator is to consult your contractor for assistance. Aside from informing you of the right location, they’ll also ensure your unit complies with local codes.
Suppose some existing electrical equipment needs to be updated to ensure your generator’s efficient operation, such as adding a subpanel near the automatic transfer switch. This scenario will only increase the costs of installing a whole house generator.
Working transfer switches are essential to have in your home, as these detect live power outages to move the power load to your generator. In portable generators, these units do not need transfer switches since they are wired into the electrical panel. Some homeowners opt to have them installed, however, to save themselves from working with extension cords.
A regular standby generator, in contrast, needs proper transfer switches to function efficiently. Your electrician can install a transfer switch at home for about four hours, which may cost you around $1,500 in installation costs.
Other Electrical Modifications
Since a whole house generator installation varies on a case-to-case basis, consider the electrical modifications for your home to be unique. You can count on your electrician to be in charge of determining the necessary upgrades needed for your existing electrical system. Here are some common examples of electrical modifications in installing a whole house generator:
The labor on the electrical panels and new wirings will typically cost you around $80 to $100 per hour. It is necessary to assess and inspect your current electrical system to determine the required electrical modifications. In turn, the more upgrades or electrical work you’ll need, the more your total installation expenses will be. Best prepare your budget for this aspect to ensure your generator will function smoothly.
With several house generator brands on the market; how do you choose the right one for your needs? Well, we believe there is a perfect unit for everyone. As long as you take your budget, preference, and purpose into account– you’ll find the generator of your dreams.
If that still proves to overwhelm your decision-making process, you can never go wrong with a trusted generator brand that has been in the market for long years. Although you will end up paying a bit more, you can expect these units to be durable and long-lasting. You may consider some crowd-favorite brands: Champion Power, DuroMax (a dual fuel hybrid generator with electric start), Durostar, and Westinghouse (a dual fuel generator).
Trust us; the investment will pay off, in the long run, to save more money on repairs and the like. These brands usually come with a warranty to ensure you’ll enjoy an efficient generator unit for a long time.
Of course, you cannot take running costs out of the equation for a whole house generator. If you want to maintain your generator’s tip-top shape, you will need to run it at least once a week. A 15-minute generator operation will cost you $8 on average, which amounts to $416 in a year just on generator maintenance. It does not account for the costs incurred in an actual and extended power outage.
It’s also crucial to have a technician assess the condition of your generator unit at least once or twice a year. Depending on your technician’s hourly rate, you can expect to pay $70 to $90 for their professional services. Should you need minor repairs, prepare to shell out $80 to $320 as well.
Key Considerations before Buying a Whole House Generator
You can expect to be charged for your whole house generator installation at a per-project cost. Depending on your contractor, however, there might be several other individual factors to take into consideration, such as:
