Whole House Generator Installation in Littleton, CO
When a power outage hits Littleton, the comfort and safety of your home shouldn't be left to chance. From winter blizzards to summer storms that can strain the local grid, an unexpected loss of electricity disrupts everything. Your heating and cooling systems shut down, food begins to spoil, and essential medical or security devices can fail. Veteran Heating, Cooling, Plumbing & Electric offers a whole house generator as your home's dedicated power solution—an investment in uninterrupted safety, security, and peace of mind.
Unlike portable generators that require manual setup and constant refueling in hazardous conditions, a whole house generator from Veteran Heating, Cooling, Plumbing & Electric works automatically. Permanently installed outside your home and connected to your electrical system, it constantly monitors the utility power. Within seconds of an outage, its automatic transfer switch (ATS) safely disconnects your home from the grid and starts the generator, restoring power to your essential circuits or your entire home. When utility power returns, the system automatically shuts down and reconnects you to the grid, ready for the next event.
The Essential Benefits of a Whole House Generator
Installing a whole house generator provides far more than just convenience; it delivers comprehensive protection for your family and property. Homeowners in Littleton choose this reliable backup power solution to secure their comfort and daily routines, regardless of external conditions.
- Uninterrupted Home Comfort and Safety: Your HVAC system is one of the first things to fail during an outage. A whole house generator ensures your furnace continues to run during a frigid Colorado winter and your air conditioner keeps you cool during summer heatwaves. Lights stay on, security systems remain active, and sump pumps continue to protect your basement from flooding.
- Protection for Appliances and Electronics: Modern homes rely on a vast network of sensitive electronics. A sudden power loss or the unstable "brownouts" that can precede it can cause irreversible damage to computers, televisions, smart home devices, and major appliances. A whole house generator provides clean, stable power, safeguarding these valuable assets from electrical surges and failures.
- Preservation of Food and Medical Supplies: A power outage lasting more than a few hours can lead to hundreds of dollars in spoiled food. For those who rely on refrigerated medications like insulin, a loss of power is a critical health risk. A generator keeps your refrigerator and freezer running, protecting your food supply and life-sustaining medical necessities.
- Seamless and Automatic Operation: The greatest advantage of a standby generator is its automatic function. There is no need to venture outside in severe weather to start a heavy, noisy portable unit. The system manages itself, providing a seamless transition to backup power so your life can continue without interruption.

Choosing the Right Generator for Your Littleton Home
Selecting the appropriate whole house generator involves more than just picking a brand. It requires a careful assessment of your home’s specific power needs, available fuel sources, and long-term performance goals.
- Standby vs. Portable Generators: While portable generators offer a temporary solution for a few small items, they are no match for the power and reliability of a whole house standby unit. Standby generators provide significantly more power, can run for days, operate automatically, and are professionally hardwired into your home for maximum safety and compliance with local electrical codes.
- Fuel Sources: Natural Gas and Propane: Most whole house generators in the Littleton area run on either natural gas or liquid propane (LP).
- Natural Gas: This is the most convenient option if your home already has a natural gas line. It provides a continuous, unlimited fuel supply, eliminating the need for refueling.
- Liquid Propane (LP): For homes without access to a natural gas line, propane is an excellent alternative. It is stored in a large tank on your property and provides a stable, long-lasting fuel source.
- Generator Sizing: A Critical Step: The most important factor in choosing a generator is correct sizing. An undersized unit will struggle to power your essentials and can be damaged from overloading. An oversized unit is inefficient and unnecessarily costly. Sizing is determined by a professional load calculation, which assesses the total wattage of the appliances and systems you wish to power. This can range from an essential-circuit model (10-14 kW) that covers basics like the furnace, refrigerator, lights, and sump pump, to a whole-home unit (22 kW and up) that can power everything, including your central air conditioner and other high-demand appliances.
