Sizing a Whole-House Generator for Your Home
Choosing the right generator involves more than just picking a model. You need to calculate your home’s essential power needs to ensure everything from your furnace to your refrigerator runs smoothly during an outage. Precision Heating & Cooling helps you plan.
When you lose power, you want peace of mind that your home will remain safe and comfortable. A whole-house generator provides that security by automatically restoring power to essential circuits. Our generator installation service is designed to give you a reliable backup power solution tailored to your specific needs.
Assess Your Home’s Essential Power Loads
The first step in selecting a generator is to determine what you need to power during an outage. This process, called a load calculation, helps us match you with a generator that can handle the demand without being oversized and inefficient. We will work with you to create a list of critical systems.
You might want to power your entire home, or you may choose to focus only on the essentials. Common priorities for homeowners include:
- Heating system, whether it is a furnace or a boiler
- Well pump for homes with private wells
- Sump pump to prevent basement flooding
- Refrigerator and freezer to protect your food
- A few key lighting circuits
- Important medical equipment
Once we understand your priorities, we can calculate the total electrical load required. This ensures the generator we recommend can start and run everything you need without overloading. With honest pricing, we provide options that fit your home and budget.
Understand Generator Power Ratings
Generators are rated in kilowatts (kW), which measures their power output. You will often see two numbers: starting watts and running watts. Understanding the difference is key to sizing your system correctly.
Many large appliances, like your air conditioner or refrigerator, require a large surge of power to start their motors. This is the starting wattage. Once running, they consume a much lower, steady amount of power, which is the running wattage. A correctly sized generator must have enough capacity to handle the initial surge of all your essential equipment.
Automatic Standby vs. Portable Systems
A whole-house generator, also known as a standby generator, is a permanent solution. It is installed outside your home and connected directly to your electrical system and fuel supply. The key component is an automatic transfer switch (ATS).
When the ATS detects a power outage, it automatically disconnects your home from the grid and signals the generator to start. Within seconds, the generator begins supplying power to your designated circuits. When utility power is restored, the ATS switches back and shuts the generator down, all without you having to do a thing.
The Installation Process Explained
A professional installation ensures your generator operates safely and reliably for years to come. Serving Comstock Park and West Michigan since 1994, we follow a careful process for every installation. Our work is performed under Michigan Mechanical Contractor licence #7111083.
Site Evaluation and Preparation
First, we visit your home to determine the best location for the generator. We consider local codes, clearance requirements, and proximity to your electrical panel and fuel source. The unit must be placed on a stable, level surface, typically a pre-cast concrete pad.
Electrical and Fuel Connections
Our team coordinates the installation of the automatic transfer switch. This switch is the brain of the system, managing the transition between utility and generator power. We then connect the generator to your home’s fuel supply, which is usually natural gas or a propane tank.
System Commissioning
After all connections are made, we perform a complete system test. We simulate a power outage to ensure the generator starts, the transfer switch operates correctly, and your home receives power as expected. We will walk you through the system’s operation and answer any questions you have.
Fuel Considerations for Your Home
Your generator’s fuel source is a major consideration. Most standby generators run on natural gas or liquid propane (LP). Each has its own advantages depending on your property’s location in Kent County.
Natural gas is convenient because it provides a continuous fuel supply directly from your utility line, so you never have to worry about refueling. If your home does not have access to natural gas, liquid propane is an excellent alternative. Propane is stored on-site in a large tank that can power your generator for days or even weeks, depending on its size and your usage.
