"Ron, our installer, was absolutely wonderful! He arrived on time, was pleasant, and efficient. Ron worked on New Year's Eve, was close to finishing his job, but could have stretched it into the next day. Rather than leaving us "in the dark," he worked until the job was completed that day. We appreciate all the hard work from Ron! We definitely recommend Reinhold for any of your electric needs!"

Electrical FAQs, answered by experts

Yes, pool pumps use a significant amount of electricity, making them one of the biggest energy consumers in a home. A pool pump can use up to three times as much electricity as a refrigerator. Typically, a residential pool pump consumes about 1 kilowatt-hour (kWh) for every hour it runs. Because pumps often need to run for about eight hours a day to properly filter the water, this can add up to an annual consumption of 3,000 to 5,000 kWh, which can cost between $480 and $800 per year based on average electricity rates.

The amount of electricity your pump uses depends on its size, energy efficiency, and daily run time. To lower your energy consumption, you can choose an energy-efficient or variable-speed pump, ensure it is correctly sized for your pool, and run it only for the minimum time required to keep the water clean.

Call your utility company immediately. Do not go outside, even in your own yard, and keep pets indoors. Downed power lines pose a serious electrocution hazard. They can also cause large power surges that could damage your appliances, so it’s a good idea to shut down power to your home if possible. If your breakers trip, leave them off until the utility company finishes its repair work.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

The doorbell installation cost depends on which and how many parts you need to replace. A new transformer is the least expensive replacement and falls between $20 and $35, plus the cost of hiring an electrician to install it, which can be between $150 and $250. Replacing your entire doorbell system can cost $250 to $400.

Yes, professional installations typically include wiring, switches, and circuit adjustments for safe operation.
