Description of Work: Flemming performed an insulation evaluation audit using infrared imaging. He was extremely knowledgeable and highly professional. I would hire again, refer to family or friends and recommend anyone in need of Thermography applications as he is a highly recognized authority in that industry.

The energy audit was thorough, professional and very informative. Flemming Lund spent several hours going through the house, and was very willing to discuss problems as they were identified and give informed opinions. Within a day I was emailed a detailed report with photos (paired infrared and visible) of all problem areas, together with a prioritized list of suggestions for improvements. Some of the problem areas identified were fairly obvious (no insulation in the walls!), but other problems were identified that were less obvious - for example, a badly finished closet where air was infiltrating through the walls. I anticipate no problems quickly recouping the cost of the audit in heating bill reductions.

I am an extremely happy customer! From the start, Flemming was extremely personable and polite on the phone, and was able to schedule my energy audit two weeks from the time I called. He was extremely punctual on the day of the appointment and arrived at 8 am on the dot. The entire audit of my two story (+basement) 2200 sq ft home took 2.75 hours from start to finish. Flemming was extremely thorough with his testing and assessments. He allowed me to shadow him while he was running the tests so I could see firsthand the results he was pulling and understand the problem areas he pinpointed. Flemming was also very kind and pleasant to my two young children who were home at the time and extremely interested in all of the cool tools and equipment running in the house! Flemming began the energy audit with a tour of the house to better understand the space. He then went back over the entire home with the infrared camera to determine if there was any missing insulation. Then he set up the blower door test, ran that completely, then went back over the entire home with the infrared camera while the fan was running to find other issues. After Flemming was done and packed up, he told me I should expect to see the energy audit report in my email within 24 hours. I was pleasantly surprised to find a full color, extremely thorough report in my inbox 12 hours after our our appointment began! In the report, after all of the pictures of problem areas and the suggested resolutions, Flemming provided a step by step list of how to fix the problems and some contractors to contact for further information. He said that we could do each step one at a time, over time, as we saw fit. Also included in the report were the technical details of the blower door test. Both reports can be brought to contractors/companies who come in to fix some of our problems. I showed the report to one energy contractor who was extremely impressed with the output of the report! While the price is high by itself, I know that by fixing even a few of the problems Flemming isolated will save us huge money, both short and long term, so the energy audit was completely worth it!! (Flemming was more thorough than the home inspector we used when purchasing our home...I highly recommend his services and company!)

It was a pleasure to work with Flemming. He was prompt, courteous, knowledgeable and took the time to answer about 100 questions I had during the inspection. He provided me a full report the same day with color photos (regular and infrared) of each problem area along with a list of suggested actions to take in priority order. I have an older home and we were able to find a variety of problems to address, some of which I was already aware of, and many I had no clue existed (such as air leaks over a window due to improperly sealed trim). If I had one ?issue? it is that a number of the problem areas are not practical to fix (very expensive and/or require wall or ceilings to be replaced). This is not a reflection on Flemming?s work, but rather the nature of this type of inspection. I was happy to find that the insulation I had installed a number of years earlier was done very well with almost no gaps. Since the inspection, I have been able to address just about all of the items that were practical. The blower door test estimated $500 per year savings so I am looking forward to tracking what I actually save on my heating bill. Final note. About a week after the inspection, I discovered my gas company was offering a rebate for these inspections. Unfortunately, Flemming was not an approved provider so I could not get the rebate. Something to consider when scheduling one of these tests.

It went very smoothly. He came on time and quickly went about his business to conduct the test. He was explicit at the beginning that I could follow along with him or go and do other things. I chose to go along with him. Flemming was friendly, answered any and all of my questions, and volunteered information and recommendations along the way. By that evening I had an electronic copy of my report. I have showed it to tow organizations as I have gotten estimates for work. Both spoke glowingly of how thorough the report was.

Flemming was great to work with. He arrived a few minutes early, introduced himself, briefly gave an overview of what he would do, and set to work. He said I could follow him through the house and ask questions or disappear and read the report he would compile. I chose to walk with him and Flemming patiently answered my questions, and offered suggestions about a number of energy related ideas (e.g., use of solar power, for what, the value of radiant heat, instant hot water heaters). He finished his work in about 3 - 3.5 hours and was on his way. I received my report that night. It was thorough and detailed. The infra red scan photos will be of great use as we work on improving our homes insulation. I highly recommend him.

Other than a little confusion over a damper in one of the fireplaces, everything went well - he was quick to respond, thorough in his audit, and pretty good-natured about coming back when we told him that the infrared audit was much of the reason we wanted the audit. You end up with a pretty big report - including photos of problem areas and infrared images (interior and exterior) showing areas of heat loss. We haven't seen enough bills (or done enough of the work) to see energy savings - but we're hopeful.
Description of Work: We had a complete home energy audit done this fall for a new home. Flemming was very thorough in his inspection, and checked out a number of different potential issues. One thing for customers to note - to get the full audit done, it has to be cold enough so you can see where heat is leaking - he had to come back with the infrared camera on a colder day, and we're glad he did, because that is the most informative part of the audit.

Fantastic. Mr. Lund called one day prior to reconfirm our appointment. On the service day, he arrived early and undertook some exterior examinations before beginning inside of the house. He began with a basement-to-attic infrared camera inspection to look for gaps in insulation, sufficiency of heating pipe and recessed lighting insulation, leaks in the central AC duct system, etc. He then set up an incredible blower door instrument that dropped the air pressure in the house to test for air leakage. Several major problems, and many minor problems, were quickly identified. The entire energy audit took about 3.5 hours, and during the audit Mr. Lund was exceptionally friendly and knowledgeable, carefully explaining everything and answering all of my questions. Later the same evening, he sent me a very detailed report that included all of the photos he had taken, with careful explanations of the problems and suggested solutions. His report also included contact information for contractors he recommends for each specific problem. Overall, Mr. Lund's energy audit was a fantastic experience! (How many contractors can you say that about?) It provided exactly what I needed, at a reasonable price, and I learned a lot in the process. I will hire Mr. Lund again in a second if the need arises.

Great. I was extremely satisfied.
Description of Work: Contacted the company by e-mail and Fleming Lund, the owner, responded the same day by phone. We discussed his credentials and expertise. Satisfied, I set an appointment for the following Monday at 8 am and he showed up on time. We discussed the energy audit and how he performed it, the equipment used and what the implications were and what a report contained. He set up the equipment and went through the process with me and then took various measurements over a 2 hour time frame. He explained in detail what he was doing and what the data was indicating as he went. Also what corrective actions I could take. At the end of 3 hours he gave me a verbal report and said he would forward a complete copy, with IR photos and all measurements, by e-mail, along with recommendations on how to correct the problems and possible vendors. I had the report by 5 pm that day. It was complete and concise. I was pleased with the company and the outcome and would highly recommend Flemming and Infrared Diagnostic.

Mr. Lund arrived exactly on time, within just a few days of calling him. was very organized, detail oriented and informative, beyond the call of duty. He did the rounds with us through our house and pointed out the areas that needed attention to prevent heat loss and put that advice in the context of our personal own needs, including many inexpensive ways to deal with heat loss and he also made us aware of the costs that would require a considerable amortization, so would not .be a 'savings' until many years after implementation. mr. Lund seemed especially knowledgeable in the unique problems to be addressed in antique homes as opposed to newer homes. He provided us with a very detailed test report of 14 pages with photos, tables and recommendations. I wish that all contractors were so knowledgeable, helpful and affordable. His audit was worthwhile investment.

It took me a long time to decide to do this because of the cost, but Flemming more than paid for himself. Independent of the energy audit he identified a few things that needed repair based on his experience as a home inspector. He also noticed many of my windows had lost their air barrier and weren't as energy efficient anymore. He recommended I call Anderson because they were within the 20 year warranty, and Anderson came out today and fixed 54 (!) of my windows, all free. I am in the process of getting estimates for the work Flemming recommended (improving the insulation in my attic, above my garage, and sealing the ductwork on our HVAC that was very leaky). I had a free energy audit by my electric company that was not infrared/blower door, and I think the recommendations are much better and more focused on clear problems areas with the infrared one. I also trust Flemming because he is independent, whereas I would wonder if the audit is done by an insulation company that wants to sell you products.
Description of Work: Flemming performed an infrared energy audit with blower door testing. He first went room by room taking pictures with his infrared camera to identify areas of heat/cold loss (depending on the season) and visually inspected the attic and basement areas. He then did the blower door test, where he uses a fan to blow air out of your front door, depressurizing the house. This allows him to see how "air tight" your home is, and identify areas where air is flowing that can be better sealed. At the end he provides an emailed report with pictures, and a summary of recommended areas for improvement.

It was very interesting. He made a lot of good suggestions. It was really interesting because my husband thought it was great but now we see things that we didn't see before.

Apex handled scheduling and my initial questions very well. The inspection was scheduled for just two days after I called. Flemming Lund performed the inspection. He arrived 30 minutes early and had completed most of the outside assessment before I arrived. He immediately reviewed his findings with me, and thoroughly answered my questions. We went through the interior together. He checked everything that I would, plus things that I would not have thought of. He went everywhere, including through a small access hole to the attic. Throughout his inspection, he took lots of pictures and notes, readily answering all my questions. It turned out the the roof is only about 10 years old-good news. The inspection took about 2-1/2 hours. He promised a report by e-mail for the next morning. The report arrived as promised. It exceeded my expectations, with many annotated pictures and color-coded findings. Flemming did a great job.
Description of Work: Apex was hired to perform a complete home inspection and provide a comprehensive report for a split-level ranch house in Woburn. We will sell this house in as-is condition, so it's important that there be no last-minute surprises. We were concerned about major deficiencies such as the age of the roof, which may be well over twenty years old.

He brought an infrared camera scope, to detect heat variations in the walls and around windows. This was very important as it indicated whether the place was well insulated and if the skylights had any leaks. This is by far gave me the greatest peace of mind. He even found a gas leak in the basement that the current owner was not aware of. His report was very complete and included photos with call outs to indicate repairs. Had it not been so detailed and had the owner not accompanied the inspection, most of the repairs would not have been done as part of the P&S. The owner did 95% of the requested internal repairs, thanks to his inspection! Highly Recommend!
Description of Work: I needed a home inspection done for a 2 br townhouse in Somerville (2 floors),plus the basement and outside of the building. The Purchase and Sale took place around the Christmas holidays, and it was a very short notice request. My call was answered by what I think was a professional call center agent who answered all my questions and booked the appointments. Oddly, he said he normally does not come out to Somerville because it's out of his normal area, but he came anyway!

Fleming was extremely thorough, knowledgeable, professional, and courteous. He discovered several problems and recommended additional inspectors to determine exactly what was going on. Because of his findings & recommendations, we were able to negotiate a lower asking price to help defray the costs of repairs. We were very impressed by how knowledgeable and thorough he was and really liked that he was able to generate the inspection report on the spot!
