- Safety: With power always available to your home, you can keep the heat or AC running as needed.

Whole-Home Generator FAQs
How do standby generators differ from portable models during an outage?
Standby generators sit outside on a pad and start automatically when utility power drops, then transfer selected circuits or the whole house through an automatic transfer switch. Portable units need to be wheeled out, fueled, started by hand, and safely connected to a few essentials. Most Monroe County and Jefferson County homeowners who want seamless backup choose a permanently installed standby system.
Do I need an automatic transfer switch or a manual interlock?
An automatic transfer switch senses the outage and switches selected loads within seconds, which keeps HVAC, refrigeration, and sump pumps running without you lifting a finger. A manual interlock requires you to be home and operate it safely. A+ Derr Heating & Cooling can size the switch and plan which circuits get priority.
What fuel makes the most sense in Louisville or Evansville?
Most standby systems run on natural gas or liquid propane. Natural gas is convenient where utility service is available. LP works well in rural areas or where gas service is not present. We can review meter capacity or tank sizing so the generator has the fuel it needs during long outages.
Where should a generator be placed for code clearances and low noise?
Pick a level pad with clear airflow, away from windows and fresh-air intakes, and outside roof runoff. Side-yard locations usually keep sound down for you and your neighbors. We’ll confirm local setback rules and manufacturer clearances before install day.
Can a standby generator run my central air and heat?
Yes, if it is sized and wired correctly. Many homes use load-management modules so large appliances like HVAC or electric ranges take turns. We’ll design a circuit list that prioritizes comfort, refrigeration, and life-safety equipment.
What maintenance keeps a standby generator ready year-round?
Plan on regular oil and filter changes, battery checks, and a visual inspection of the fuel supply and exhaust. Most systems perform a brief automatic exercise each week. A+ Derr Heating & Cooling can set a maintenance schedule that matches local weather and usage.
How long is the transfer time when the power fails?
With an automatic transfer switch, most homes see a short pause while the unit starts and the switch transfers selected loads. Refrigerators and HVAC typically ride through that gap without issues.
Do I need permits or inspections for a whole-home generator?
Yes in most municipalities. Electrical and fuel connections are inspected to ensure safe operation. Our team handles the paperwork and schedules inspections in Louisville, Evansville, and surrounding communities.
How loud are modern standby generators and what can reduce sound?
Enclosures and sound-absorbing designs keep noise far lower than older models. Good placement, a level pad, and clear airflow reduce vibration and help keep the unit quiet during its weekly exercise cycle.
Will surge protection still matter if I install a generator?
Yes. Utility switching, storms, and large motor loads can create voltage spikes whether you are on utility power or generator power. Whole-home surge protection and proper grounding add a layer of safety for sensitive electronics.
