Best energy efficiency auditors near O Fallon, MO

"Estimate and service were completed quickly. Price seemed very fair and was less than estimated. Work was high quality. Office team and plumber was very easy to work with. I would highly recommend."

"I was totally satisfied with this Company from the beginning to the end. I scheduled an appointment and was seen right away. A representative came to my home and assessed what I needed to have done. The price was reasonable and the work was completed in a timely fashion. I would recommend this Company in a HEARTBEAT!! Thanks for ALL that you DO!!"

"Fantastic experience with Paul, Mindy and their team when they helped us insulate the attic spaces surrounding and above our 1.5 story house. We have immediately seen the benefit from the insulation through our energy consumption, reducing the run-time of our unit by ~4 hours a day on like-weather days. This team will take care of your exact needs by tailoring their solutions to your specific situation and they don't cut any corners in ensuring your getting the value deserved!"

"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"After purchasing a Deal for a home energy audit, Paul Peterson and his wife came on the scheduled day and checked the house for air loss to the outside.  They sealed the front door with a plastic 'door' with an exhaust fan to pull in cooler outside air.  They then took pictures with a camera that showed cold/hot  areas.After inspecting attic and basement he made several suggestions as well as promising to send an estimate of work.  After I received that I eliminated some work that could be done by family and agreed to the rest.  A date was set and the workers came promptly on that day.
There were 4 workers and each of them was courteous, friendly and competent.  Work was explained and I was kept informed of
everything that was done.  They were dog friendly and cautious about closing gates while working.
At the end of the job Paul mentioned one thing that he had not bid but that needed to be done to bring everything up to code.  He said he would have his crew come by and take care of it at no cost when they were in the area.  This was done a week or so later.  I have confidence that this is an honorable company that stands behind their work and word.
