"Very pleased with the finished work. Donny did a great job with everything, he really knows what he is doing. Put a new service entrance in, new breaker box in the basement, fixed up an old dryer plug and some new wiring. I have a few other smaller projects and he will be my go to guy. Thanks again Donny."

"They did a great job. They stopped by and gave me a breakdown of my electrical use and estimates on different options for a generator. They also found the perfect spot to put it. The day of installation, they showed up on time and put in a full day installing the generator. It works great and looks great. Now I don't have to worry about outages, especially in the winter."

"We hired Shalkham Electric because we wanted a garage heater put up. The day before they came I pulled the cord right out of my ceiling fan. We bought a new fan and they also installed the fan for us. I was very happy with the two men that came to my home. They were polite and had great personalities. I would be happy to recommend this company to anyone that needs work done around their home. Thank you all!"

"The team effort was amazing to watch.  Along with the owner, the guys (Anthony and Joey) were impressive with their knowlege as well as answering my questions.  They were eager to answer and still kept busy with their tasks.  It has been a long time since I witnessed employees who not only cared, but worked extremely well together.  Newtown heating and A/C has a lot to be proud to perform in such a professional envoronment.  They are super.

Parts were made on site or in their nearby shop to custom fit the heat exchanger to my current duct work.  I am very happy with the state-of-the-art equipment installed.  I feel very comfortable with my new system and highly recommed contacting them.

The system has been working perfectly.  On 2/10/2014 I called about a message code and service was prompt.  The problem was with my internet service unable to download some new software as a result of the power outages from the recent snow/ice storm.

I am very interested in some additional work for a battery backup for my sump pump.  I am requesting additional information about a full home generator.

Also, they cleaned up after the installation and removed all of the old equipment.

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
