Jim and his crews just finished working on my home in Santa Rosa. It was built in 1950 and was in serious need of some energy upgrades. The job encompassed: Home energy audit, new attic and ceiling insulation, new dual pane vinyl windows, new furnace and ducts, new efficient water heater, sealing of all air leaks, and final testing of the home for any air leaks (there were none!!).

I am absolutely pleased with the excellent customer service and work product of the folks at Apperson Energy!  From Jim, the owner, to the great work crew--- Vince, Sergio, and Lazaro--- this company is one I have no hesitation recommending.  The crew is courteous and respectful---they work hard without a lot of "bother", keep you informed about the work and leave the premises neat and clean.  The price is competitive and they don't try to sell you things you don't need!  Plus Jim is very helpful with filling and filing the paperwork for rebates and incentives and keeping you informed about it.  They do a very good job!

The work was done very professionally, the workers were great. They answered questions, the workmanship excellent, they left the home clean and neat. Definitely will recommend Apperson EM to others!

Everything was great! We had our attic insulation removed and reinstalled due to rodent problems. The crew was professional, did a great job and we are very happy with the results. They even did some air sealing while they were up in the attic, which was a very pleasant surprise. I had no idea what air sealing was until Jim explained it to me, and now I'm very happy that it was done.

I'm really enjoying the upgrades. The light tubes are exactly what I was seeking not having to turn on lights during the day when my solar panels are selling power ar peak demand. The hot water pump delivers to the far end of the house & bathroom wasting less water. The house didn't reach 80 in the recent 100 days as in previous years due to the tighter, better insulated house. Still haven't got a PG & E bill yet to see a difference but one of the inverters was replaced so system may not be operating at full capacity yet.

The initial goal was to locate a local business for a home insulation evaluation. I was quickly put off by the overabundance of outfits that responded to my internet search by interviewing over the phone before providing firms to choose. One local firm that I contacted directly made an unimpressive evaluation. Fortunately, of several referrals made to me, one was very responsive, not only over the phone but in all subsequent contacts, including home evaluation,attic insulation and workmanship--including a return visit without charge to repair a ceiling hole in a closet that was unknown to them and to me: Apperson.

This was a very seamless process. Apperson Energy Management did the work and took care of all the paper work. The only thing I had to do was sign some paperwork when they were done. As the weather is starting to get warm, I have really noticed a difference and wonder why I didn't do this when I was first approached over a year ago.

When the sale of my home finalized, the first person I contacted was Jim Apperson. I wanted to make it energy efficient. First he evaluated its performance and suggested several options prioritized by payback period. He also referred me to reputable contractors for the work his firm doesn't perform. For some items I chose my own contractors. He accommodated my working on those parts of the job I could do myself. Jim coached me on being the general contractor, a job that was new for me. I ended up with a home whose energy systems are integrated and efficient. There was a huge difference between the pre- and… (read more)

Jim is very very good about giving you all the information and getting back to you. This is much appreciated. He also is very easy to do business with and extremely flexible. His guys came and put extra insulation in my attic and were in and out with hardly any signs they were ever here.

We had great interaction with Jim Apperson from day one.
