"I had my panel and external service replaced. Cindy helped with scheduling and arranging for the inspection afterwards. On the day of the scheduled work, Evan arrived promptly, did a great job with the work, and answered all of my questions. Evan had also been out previously to give the quote for the work and was very thorough in his inspection and explained the reasons for all of his recommendations. Previous owners of my house had hired contractors that did some shoddy work. While Gen3 is not the cheapest quote you will find, they do their work properly and to code. I would definitely recommend Gen3 to others needing to do electrical work."

"My 10-year old air conditioner was not cooling . I tried replacing the outdoor unit capacitor but this didn't fix the problem. I took advantage of Harmon Heating 's $30 check up fee and my unit was diagnosed with an evaporator leak.  Bruce (the business owner) explained to me that the cost of fixing it (about $1750) is not worth it because of the age and that the type of refrigerant being used (R-22 or Freon) is being phased out. He provided a comprehensive website with all options available to me. I did my due diligence by researching the market  to make sure that I wasn't being taken advantage of. I found that the prices are reasonable (of course, I would have saved a lot of money if I buy the equipment myself but that will be too risky and I do understand that businesses need to make money too). I wasn't at all pressured to totally replace my  system. Since I'm an avid environmentalist  (I drive a Prius and watched all episodes of Cosmos) and have the cash to spend, I decided to replace the unit with a newer, more energy efficient model that use less harmful refrigerant (Puron). I also decided to replace the furnace with a more efficient model to maximize the efficiency of the whole system. When I expressed interest with one option, Bruce came back the next day to perform a load calculation on the house to make sure that the tonnage is right for my house. The results of this calculation was given to me right after the installation. The installation commenced the same week and took only one day. Bruce performed the work himself (with the help of an assistant). After the install, proper cleanup of the site was performed. He patiently answered all my questions. He also explained to me that the gas supplier needs to adjust the pressure and that he'll return in the fall to make sure this is done as it is essential for the system to work correctly. When I complained about the furnace using the old condenser pump, he explained that it wasn't part of the original contract. But he returned the next day with a new condenser pump even without being asked, to make sure that I'm 100% satisfied. He also helped me with the rebate process (I got $400 rebate from Peco). When Peco's website appeared to not recognize the model as 'rebatable' . I emailed Bruce and I got the assurance that he'll pay me the amount of the rebate himself (and in turn get the supplier to reimburse him). Fortunately, this did not have to happen as Peco already sent me the check. I'm very satisfied with the new system and the overall experience with the service provider.

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"Estimator came out quickly, was very personable, and could schedule my install appointment a few weeks later right then and there. When the tech came out he was polite, efficient, and very quick.  Overall I was very happy with the service and would recommend them to others if the price is competitive with another company.

". the work was being done was  at best puzzling and cast a shadow over the entire experience. What makes this review diffulcut is that I want to give higher marks for the work that was done since we have not had any problems to date but the fact that even after they called to set up one last visit to tie up some remainig concerns they never showed up and this makes it diffulcult to have positive feelings. Questions about the supposedly HOME SURGE PROTECTION system and WARRANTY and how to handle any future issues regarding it have never been explained or paperwork supplied. When it is so hard to reach the boss it creates  an environment of distrust be it real or imagined.

Energy Efficiency Auditing questions, answered by experts

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200
