"Please Read my entire review: I had another contractor (ABC) come out to my home and told me I needed a blower motor assembly and the cost would be $1500, and was told I should also look into purchasing a new entire unit. after checking this site and seeing that the most I should pay is around $800 and confirming that the part was under $300 I decided to contact another company AIR SOLUTIONS MECHANICAL SERVICES,INC and upon arrival it took Robert approximately 12 minutes to determine that the blower motor assembly was just fine and had no problems at all and had it up and working immediately. He also determined that I had a bad capacitor which is a part I have replaced a handful of times. I really want to thank Robert and thank this company as it truly is an honest and trustworthy company that not only will I recommend to all my friends but to the Angie list community to use for all your air conditioning and heating needs as I will most definitely will be calling them for all of mine. On a side note this happened on the hottest day and week of the year and I was out of town at the time ABC Plumbing Heating Cooling & Electric 220 West Campus Drive Suite 200 Arlington Heights, IL 60004 came out to my home telling me that I needed to spend $1500 and look into purchasing a new unit which would of been as you all know at least $3000. I wanted to make sure the Angie list community was aware of this deceptive company and their deceptive practices. I also contacted them and received a response that they wouldn't pay the $225 I paid to fix the unit but again were willing to make me spend $1500 - $3000 on a repair that was 100% not necessary and not needed. They took full advantage of the weather and me being out of town to be very deceptive. I have ALL the paper work to confirm everything."

"39% drop in energy bill during the winter! Upstairs furnace maybe ran 14 times during winter. Was relieved to hear it kick on just because I knew it was still working. Best home improvement we have done other than putting hydronic heated garage floor in.

"They were very good. They did everything they said they were going to do. It was a little bit of a problem getting the electrician to come, but then they arranged for another electrician to install the sun pump. And they arranged to meet the electrician at my house and made sure everything was done right. So it was a good job. They were the lowest bid by about $300 of three different companies. They called right away and followed up on calls. They checked everything afterwards to make sure it was OK. They knew what they were doing."

Energy Efficiency Auditing FAQs, answered by experts

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.
