"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
The Steam Whisperer
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."

FAQs for energy efficiency auditing projects in Posen, IL
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
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.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
