"Jeffrey arrived on time and was responsive. However, Jeff missed a VERY crucial, important and now COSTLY expense for my husband and I to NOW repair. Jeff missed many concerns with our front door. It has major gaps, wood rot and the door also hits the front step as you open the door. A few weeks after moving in we noticed our house was FREEZING and it was all due to the front door. The ENTIRE door needs to be replaced and I am so angry he did NOT catch this. This is costing us thousands of dollars to replace. Would NOT recommend Jeff to anyone. On our report under major concerns: he put none. Items reaching the end of their life or need replacement in the next 5 years : he put none. Items to monitor: he put none. Do not hire Jeff. Now thousands of dollars in the hole."

The Steam Whisperer specializes in steam heating systems. We believe these are the "Greenest" heating systems around, with dramatically lower fuel and electricity use when compared to typical newer systems. We have increasingly become specialized in steam heating in the Chicago area (our main steam heat market), using advanced methods and new technologies to restore or increase the efficiency and comfort of these systems to the highest modern standards. We also travel extensively to bring our knowledge to steam system owners wherever it is required. We can "virtually" resize old systems so they will appropriately match remodeled buildings. We are helping lead the redevelopment and expansion of steam heating in response to needs for improved energy efficiency, conducting experimental work and testing in the steam heating field for publication. Typical Clients - We work with homeowners, condo associations, commercial property owners, and churches to resolve their steam heating problems and give them options of which they were not aware. We occasionally bring in other specialists whose knowledge exceeds ours in particular areas (such as certified chimney sweeps). We are a small company with two full time help, but have completed substantial projects. We provide consulting services and can complete almost any work in Chicago, and nearby communities. We enjoy showing how these grand old heating systems can be made to shine again for a fraction of the cost of replacing them with other systems than cannot provide the comfort, health and efficiency of steam heat at its finest. We enjoy providing solutions that most believe are not possible, but work. The radiant comfort, room by room temperature control, increased humidity, virtually freeze proof and dust free operation of steam heat cannot be matched. Additional phone number - 773-779-5740.

"Steam Whisperer was excellent. I spent an hour on the phone with Dave who provided me a TON of information to help me better understand the mechanics of the steam heat system in our home and potential explanations for issues we were having with banging radiators. The maintenance and repiping work was professional and prompt, including calm and professional management of the issue when the old water supply line began to leak during the repair due to our pipes being quite old in the home. We had previously worked with another provider who was not specialized in steam, and the quality of service provided by Steam Whisperer was dramatically better than other providers and the hourly rate is 40% less than another well-known heating company in our area."

"This is the most negligent contractor I've dealt with in my life. They suggested to not be home for our attic insulation since we have a newborn at home which I appreciated. They seemed careful and thoughtful in the sales process which is why I ended up picking them for our project. However, when it came time for the job they were reckless with security and safety. Before the job I sent multiple notes via text and email, and had a phone call asking them to contact me at the end of each day so I could set the alarm and lock the doors remotely. Day one they didn't do this. I sent another ask to please be mindful of this so I could keep our home secure. Day 2 they did not do this again, and ended up leaving our front door wide open which triggered a burglar alarm at 2am requiring us to deal with the security company and police throughout the night. Afterwards it took days for anyone to reply. They lacked empathy or ownership for how negligent their team was. I would not recommend working with these people. Mistakes happen, but the response to these mistakes was almost as bad as their dangerous actions themselves."

"We just had our attic and crawl space insulated and a moisture barrier put in. The crew showed up on time and every one of them was polite and professional. We could tell they had a lot of experience working together because they were super organized. While the boss, Dave, walked us through the process in detail, making sure we understood the job, behind him the crew set up quickly and efficiently, treating our home with respect. They were finished right on time, too, and left our house looking as if they had never been there. Before they left, Dave showed us their work and explained how these improvements would make our home more energy efficient. Every crew member made sure to say goodbye to us. They were amazing people!

Energy Efficiency Auditing questions, answered by experts

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
