"My loft above my garage was humid and a bit uncomfortable from what I was expecting. I’ve watched enough home repair shows and understand air flow enough to know it would never be perfect, but something was off because of the humidity issues. Mike came in and did an inspection, confirming that there was a lot of room for improvement in the garage ceiling. The heat camera was showing that there was a lot of heat transfer happening in the loft, foot prints (from boots) leaving heat transfer marks which is unusual and recommended dense insulation pack to fill the void. I sat on it for a few weeks, called and scheduled for the 17th, but got in early due to an opening. It took several hours to complete the work, and the folks said it had 5” bat insulation but a 17” void, which confirmed Mike’s original thought that there was a gap between the insulation and the loft floor which was carrying the heat from the outside into the floor."

"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."

Energy Efficiency Auditing questions, answered by experts

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.
