Malakoff, TX Standby Generator Installation & Maintenance Guide

Estimated Read Time: 9 minutes

Power outages do not wait for a convenient time. Whole house generator sizing is the key to keeping your HVAC, fridge, lights, and medical devices running when the grid fails. In East Texas, fast summer storms and winter ice can knock out power for hours. This guide shows you how to choose the right size generator with confidence, avoid costly mistakes, and get a seamless install that is ready in days, not weeks.

Whole-House Coverage vs Essential Circuits

Not every home needs every circuit backed up. Your first choice is coverage strategy.

• Essential-circuit systems power the must-haves. Think HVAC, refrigerator and freezer, well or sump pump, kitchen plugs, a few lights, security, and medical devices.
• Whole-house systems power your entire panel. They give you normal living during an outage and remove guesswork over which circuits stay on.

The right path depends on square footage, HVAC tonnage, well or pool equipment, the number of large appliances, and your comfort goals. Many homeowners in Tyler, Longview, and Texarkana choose essential-circuit coverage sized to run a central AC plus key loads. If you work from home or have medical needs, whole-house coverage gives maximum peace of mind.

Step 1: List Your Critical Loads

Create a simple list with two columns: running watts and starting watts. Starting watts apply to motors and compressors that surge at startup.

Common examples:

1. Central AC or heat pump
   • 2 to 5 tons. Running 2.5 to 5 kW. Starting 6 to 20 kW depending on the unit.
2. Air handler or furnace blower
   • Running 400 to 800 W. Small start surge.
3. Refrigerator and freezer
   • Running 150 to 700 W each. Start surge up to 1,200 to 2,200 W.
4. Well pump or sump pump
   • Running 700 W to 2 kW. Start surge 2 to 4 times running watts.
5. Electric water heater
   • 4.5 to 5.5 kW running. No major start surge.
6. Lights and outlets
   • Tally by room. LED lighting is efficient, often under 500 W for a whole floor.
7. Range and dryer
   • 5 to 7 kW each if electric. Consider whether you need these during an outage.

Tip: Your HVAC nameplate, appliance manuals, and breaker labels help you estimate. A free site evaluation can confirm numbers with meter readings.

Step 2: Add Running Loads, Then Account for Starting Surges

Start with the total of likely running loads. Then add the largest single start surge. This method prevents oversizing while protecting against nuisance trips.

Example for a 2,200 sq ft East Texas home with a 4-ton heat pump, fridge, freezer, lights, outlets, and a well pump:

• Running total: 7.5 to 9.5 kW
• Largest start surge: 8 to 12 kW from the heat pump
• Practical generator size: 18 to 22 kW with smart load management

KOHLER PowerBoost technology and Generac load-shedding modules can stagger heavy starts so a 20 to 22 kW unit covers more than you expect without dimming lights.

Step 3: Choose Fuel and Understand Derating

Residential standby generators run on natural gas or liquid propane. Your fuel choice affects output.

• Natural gas is convenient if you have a utility line. It offers continuous supply and no refills.
• Propane is ideal for rural properties without a gas main. Pair with an adequate tank size for multi-day outages.

Important: All engines produce slightly less power in high heat or at altitude. East Texas heat can push summer temps past 95 degrees. A proper load calc includes a safety margin so your generator performs on the hottest day of the year.

Step 4: Decide on Transfer Switch and Circuit Strategy

Your automatic transfer switch, or ATS, senses utility loss, starts the generator, and switches your home to backup power. When the grid returns, it switches back and cools the unit down. The ATS is the brains of the system.

Options:

1. Essential-circuit ATS with subpanel
   • Only selected circuits run on generator power. Great for 12 to 18 kW systems.
2. Service-rated whole-house ATS
   • Powers the full panel and can use load management modules to prioritize big appliances. Best for 18 to 26 kW and up.

The right ATS prevents overloads and avoids manual steps in the dark. Tri-State includes automatic transfer switches and remote status monitors, so you always know your system is ready.

What Common Generator Sizes Actually Power

Product pages often show capacity ranges. Here is what our factory-trained electricians see daily in the field:

• 12 kW to 14 kW
  • Good for essentials in smaller homes. One central AC up to 3 tons, fridge, lights, outlets, and a well or sump pump using smart management.
• 18 kW to 20 kW
  • The sweet spot for many 2,000 to 3,000 sq ft homes. One 4-ton HVAC, fridge and freezer, kitchen circuits, and lighting without stress.
• 22 kW to 26 kW
  • Strong choice for larger homes or multiple HVAC units. Supports two compressors if starts are managed, plus major appliances.
• 30 kW to 80 kW
  • Whole-estate coverage. Needed for very large homes, guest suites, or heavy electric cooking and drying during outages.

KOHLER units are known for fast response in about 10 seconds. Pair that with weekly system checks and you get reliable coverage that just works.

Sizing Mistakes That Lead to Headaches

Avoid these common pitfalls that drive cost and frustration.

1. Ignoring starting watts
   • A unit sized only for running loads will stumble when the AC kicks on.
2. Forgetting future upgrades
   • Outdoor kitchen, EV charger, or a pool pump next year. Plan now to avoid replacing the generator later.
3. Overlooking fuel supply
   • Undersized gas meters or propane tanks starve the engine under load.
4. Skipping a load study
   • Online calculators are helpful, but an on-site evaluation catches real-world factors.
5. Choosing manual transfer
   • Manual switches are slower and less safe for sensitive electronics and medical gear.
