"Dan did a great job of going through everything very thoroughly with me and pointing out a plan of remedy for the aspects of my home that seemed most significant to least significant. I would recommend him in the future for anyone looking to get an understanding of their home energy performance."

"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"Climate Master is great! They are honest, flexible, and on top of every detail. Just before the holidays our 20 year old furnace went out. The team at Climate Master gave us a second opinion, more choices around payment, and got us back up and running through the holidays until their crew could come out and replace our old furnace and A/C with new units. Without their help, our holidays would have been miserably cold. They put in a state of the art 2-stage Bryant Furnace and AC with IoT Thermostat. They also included all the rebate paperwork to make it super easy."

"I found Millennium Solar Electric through an Angie's List offer to have an electrical panel replaced with an upgraded panel with a whole home surge protector where you have to pay for the service in full before scheduling the services. Paying a service provider in full before they do any work is quite the leap of faith and goes against rules of dealing with service providers but it is the only way to take advantage of the offers. In an attempt to protect myself I contacted Millennium prior to making payment. The company did not respond to contact attempts through Angie's List email and chat service. I attempted to contact them several times that way throughout October 2017. I finally got in touch with them on November 1st. They apologized for not responding to my attempts to contact them through Angie's List. November 17th was earliest he could schedule my appointment. The work seemed to go off without much of a hitch. When they finished installing the panel, the workers left without much explanation of what what done. I noticed after they left that one of the breakers was not turned on. It was the breaker connected to the whole home surge protector. I wasn't sure if it was supposed to be on or off so I called the company and had to leave a message. A few days later I finally received a response telling me that the breaker should have indeed been turned on. OK, I thought, not a big deal. A week later I noticed that my outdoor security light was no longer working. It was working prior to the installation of the panel. So again I had to call the company. I called on December 1st, left a message. He called me back, stated that he knew what probably went wrong with the wiring when he reconnected the panel but said that he would me back to schedule a time to come correct the problem. I didn't hear back that day so I called on December 4th, 5th, and 6th. On the 6th I again explained the issue as he didn't seem to remember and we made an appointment for December 11th to correct the problem. So I took off work and waited for him to come correct the issue. Guess what....I didn't hear from him on December 11th. I called and find out what happened and the calls went directly to voice mail. I waited an hour and called again and left a message. That is where our story ends for now. I must not contemplate having another company correct the issue which would mean I would have to sue this company for whatever the amount I am charged to have the light fixed. Between December 11th and December 14th, the owner, Christopher Williams and I had a couple of exchanges via text. I think in the end, Mr. Williams understood my frustration and on December 16th he came out as promised (actually he was early) and corrected the issue with the outdoor security light. Now that my issues are resolved I have a much more favorable view of the company."

"Excellent! They came the same day I called. Thoroughly cleaned the blower unit, we have dogs and cats. He also checked the hot water tank as a courtesy. Offered a maintenance program for a small fee, pay ahead for maintenance and call us to remind us when services are due to be done. and they did this! This service was worth every penny! I referred them to the buyers of our house when we moved. Excellent company, I recommend them highly."

"Alberto was great. Upgraded us to 100 Amp service and brought some organization to the chaos that was my electrical box (we didn't know it was out of code when we bought the house). Currently in the process of getting more work done with him, so yeah, I highly recommend."

Energy Efficiency Auditing questions, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

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.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.
