"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.

"When we bought this house we were planning to renovate the basement.  The previous owner had represented that it had never taken on water.  The first weekend we were here, however, a torrential rainstorm caused the basement to flood.  We realized we needed to waterproof it before we could do anything else, and decided that drain tiling was the safest way to go.
Greg was phenomenally responsive from the start.  He was very clear about what needed to be done and how they would do it.  He also described some optional work but was explicit that it was optional and if it didn't fit within our budget that was that, and he wasn't going to push it the slightest bit.  His quote blew away the bigger, well-known firm and was less than or on a par with some others.  He also agreed to demo the walls for a slight extra charge, which otherwise would have been a huge convenience for us.  Between then and the start of work I emailed him repeatedly with various questions and he responded almost instantly.  When his workers took down the paneling we got the unpleasant news that we had huge cracks in the walls that would need to be tuckpointed and in one area a big chunk of foundation was jutting from the wall.  That section of the foundation would need to be replaced and a support beam installed.  We were more or less at Greg's mercy at this point -- we weren't going to halt work and bring in a series of guys to quote the tuckpointing & repair -- but Greg gave us an estimate of $2,600-$3,000.  We can't know for sure, but suspect that this price was more than fair, and Greg stuck to it even though we think the work turned out to be more than they expected.
The project manager, Jim, was fantastic to work with throughout, very communicative and accomodating, and the crew of five guys or so was extremely friendly and professional.  All in all, A Perfect Crawlspace was a pleasure to work with and we could not be happier with the results.

Energy Efficiency Auditing FAQs, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

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.
