"This is the second year I?ve had them out to my kids house. My son is special needs my daughter is 19 and works three jobs to help their mom who isn?t in the greatest health so AC is important for her as well as the kids who sleep upstairs. Tammy got someone out right away Caleb showed up within hours while I was on the phone. There was no high pressure sales and we are good for another yr, Bless God! Tammy even signed my ex up on a service plan to look after the aging equipment. Couldn?t be happier!!! Referred another person a friend in Broad Ripple; She just had surgery and is ready to replace. She is super happy with them too. Wouldn?t trust anyone else but Irish Air. Am telling everyone!!!"

"When I called, after normal hours, I was answered right away by a live person and was able to set up an appointment for a few days later. They called the night before to confirm, and called again a half hour before they arrived. The technician, Chris, not only performed the tuneup, but found and fixed a wiring error I made in in the Smart Thermostat I bought and installed myself a few days prior and gave me some advice on programming it for maximum efficiency. Very happy with the service!"

"We contacted Angie’s List for recommendations for Blow-in Insulation to refresh older insulation in our attic. Three companies we recommended to us. Two phoned the next day. I never heard from the third. I told both I was gathering information and would call to schedule an estimate. I called and scheduled two companies, including USA Insulation, to come make an estimate. One company called one minute before scheduled and wanted to re-schedule. Chris from USA was on time. We were pleased with his offer and accepted. He scheduled the installation for the next day. William and his helper arrived, set everything up, and went to work. I checked regularly and photographed the attic. When they were through, they thoroughly cleaned the area. We were quite pleased. Shortly after completion, Michael, a company inspector, arrived to check the work. I would give the company an A+."

"I had called four different companies to provide estimates to fix my sump pump pipe that went out through the front of my home. Three estimates were somewhat close to each other in price and how to make the repair except for one which was very different. My friend recommended that I call a guy named Jonathan with WonDrain. He did drain repair for her boss and word spread fast around her office on how he did a fantastic job. Jonathan was the first one scheduled to meet with me and also the only one of them to show me with a borescope what was blocking the pipe. He was very funny and knowledgeable. He took the time to explain how everything worked and what to expect in the end from most companies. He marked in detail the pipes exact locations with depth in the yard to help the next company with their bid. I didn't know why he would do that and thought it was strange, but then he was a bit quirky. We hired WonDrain because not only were they less expensive by almost 20% but Jonathan was absolutely correct on how everyone would bid the job. The other 3 companies all bid the same way and Jonathan's reason why they did made sense. In the end and true to word of what my friend said not only did they cost less but they made my yard look so much better than it did before I had the problem pipe. My neighbor who had his pipe dug last year and still has a small pile of dirt left thought we hired a landscaping company and not a plumber."

Energy Efficiency Auditing FAQs, answered by experts

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.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.
