"He's a really friendly guy, very responsive to my calls, schedules me in partly because we've had a working relationship for like six years. He's done work at the house that I live in. He replaced a furnace there and the air conditioner. The day before the warranty of the air conditioner that he had installed ran out, he installed a new one and it didn't work either. He went to the local manufacturer's distribution and got a third one and it didn't work either so he went and got me a brand new upgraded unit and a discount for all the inconvenience. He's a good guy and I have no complaints whatsoever. Sometimes, some of the worker bees that he sends when he is on a job and somebody has to come and check something, they come right away but they are not necessarily as diligent as he is."

"They arrived right on time and were the most professional, careful, and considerate group of insulation professionals I could have asked for! They performed all work exactly as quoted and explained everything as they progressed. I especially loved how careful they were with our belongings and covered everything and every stairway with plastic from start to finish. When finished, they cleaned up so well you would never know they were in your house if you didn't see the new insulation! I would highly recommend this company to anyone needing insulation professionals that tell you exactly what they are going to do, doing exactly what they said they were going to do, and cleaning up so well you will be amazed! 100% satisfied customer!!!"

"Donohue’s lightning protection done me a wonderful job. Our neighbors house was struck and it scared us so we did some researching and found there company. There was 300 miles between us and Seamus said that was no problem he will start our way because he had a high call volume in our area. After weighing our options we decided to have Donohue’s do it and I couldn’t be happier we feel much safer in our home."

Energy Efficiency Auditing FAQs, answered by experts

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

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.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.
