Installation & Replacements

Power and Peace of Mind for East Texas Homes & Businesses

Don't let the next East Texas storm or grid uncertainty leave your family in the dark. At TDi Services, we understand how crucial reliable power is for your comfort, safety, and daily life in the Tyler and Longview areas.



As the trusted local experts for HVAC and now comprehensive electrical services, TDi Services offers professional whole house standby generator installation and replacement. We provide a seamless, turn-key solution to ensure you have dependable backup power exactly when you need it.

A whole house standby generator is not a luxury—it's an essential investment for property owners in East Texas. The unpredictable Texas weather, from severe summer heat waves to winter freezes, and the resulting strain on the power grid make a permanent backup solution vital.

• 24/7 Automatic Protection: Your standby generator senses a power outage and automatically switches on, typically within seconds, so you barely notice the lights flickered.
• Keep Your HVAC Running: Maintain a comfortable and safe indoor temperature by ensuring your central air conditioning or furnace continues to operate, a critical need in Tyler and Longview.
• Protect Your Essentials: Keep major appliances like refrigerators and freezers running, preventing hundreds of dollars in food spoilage.
• Continuous Operation: Unlike portable units, standby generators run on your home’s existing natural gas or liquid propane (LP) supply, eliminating the need for constant, manual refueling.
• Increased Home Value: A whole-house backup system is a major selling point and can increase your home's resale value.
