Zach did my home inspection today. I am familiar with home building and other parts of the construction industry and he convinced me without a doubt that he knows what to look for and is representing the buyer's interest. The pricing is fair too since it is based on sq/ft. Zach walked us through the property showing us concerns and explained why it was important and a few options you could go to resolve the concern. I plan to update this review after I get the final report which I have been told will include all of his evaluations with photos. read more

Wow, Zach is super amazing. He came out for an energy audit and was courteous and patient with all of my questions. His knowledge and experience is incredible. I had him come back a few weeks later for weatherization and insulation work. He worked all day getting a ton of things done. He sealed every air leak in our attic, installed baffles for air flow, insulated our vent ducting, re-routed and insulated bathroom ducting, found a couple things that weren't up to code which he fixed, and then blew in more insulation. The whole experience of working with Zach and Premium Efficiency was superb. Communication was quick and professional. Emails and phone calls were returned promptly. I was using an EWEB incentive program and Zach was great with the process; he knew exactly what they needed and was well versed in the process. It is clear that Zach is passionate about energy efficiency and takes great pride in his work. I would highly recommend him to anyone who wants quality work from a solid local company. read more

I just got a new heat pump with indoor furnace and air conditioning installed by Jco. They hire Premium Efficiency to do testing to be sure everything was installed properly and that the system is working efficiently. This fact really impresses me! Zach came out this afternoon and did the work. As other reviewers have all said, Zach is extremely knowledgeable and personable too. He's high energy and worked very quickly with a lot of equipment. He also completed the paperwork that will be required by EWEB for my incentive program. I highly recommend him too! It was a very good experience. read more

I can not find enough words to tell you how incredible these guys are. Zach Erdman runs a great company and they did a huge repair to our house. He is attentive, knowledgable, and a very hard worker. He found construction problems beyond the scope of his duct and insulation bid and attended to every single detail without missing a beat. His team does solid work and they are polite and professional. read more

We hired Premium Efficiency to inspect a duplex we are looking at purchasing. They were fairly priced, and even have a discount for veterans, which was a plus! The report was very thorough, and we are pleased with the quality of service we received from Zach. We will definitely plan on hiring them again if we need any inspections done, and our realtor has already hired them again as well. Highly recommended. read more

We are extremely pleased with the work done by Premium Efficiency. We live in a 2900 sf home that was renovated 8 years ago. Part of the original heating duct system was replaced at one end of the home and connected to the original duct system at the other end of the home. After going through our first winter, we were concerned that one end of the home (the refurbished end) was toasty warm, whereas the other end of the home was really cold and uncomfortable. After many years of just living with this, we decided to contact Premium Efficiency to see if they could figure out why we had such a heating/cooling differential in the home. This company had been recommended by someone in the construction industry. Zach, the owner of Premium Efficiency, came to our home to do an inspection and to work up a proposal. He spent at least 2 hours on his initial visit, sealing off all of the vents and conducting a test of the house leakage. His test revealed a large leakage of air in the TV room, whereupon he discovered a hidden hole in the ceiling (where an old air intake grate had once been) that was causing warm air to flow out of the room and into the attic. Zach also crawled underneath the home and with pictures taken on his iPad, showed us how the insulation was falling down from the floor and how the heating duct system was all curvy which resulted in less efficiency in carrying the heat from one side of the home to the other. He also conducted a duct leakage test. Zach also included information in his proposal about the EWEB incentive program, which would partially compensate us for the work done because of the energy savings that would result. Our project was a large one, so it took 7 days. The crew that was brought in was professional and courteous. At the end of the project, Zach came back to conduct another round of leakage testing (house and duct) and to ensure that all of the work done under the house met his high standards. His leakage testing showed dramatic improvement. He took before & after photos of the work done under the house. In Zach's final billing, he reduced the cost of his bid to account for the fact that slightly less insulation work was done than originally proposed because a small area under the house was determined to be inaccessible. All in all, Zach is honest, trustworthy and hardworking. He was also responsive to our requests in a timely manner. We would definitely use him again. In fact, he encouraged us to call him if, during the winter, we felt that we needed additional tweaking to the heating vents to ensure a more even flow of heat. read more

Had owner, Zach, out to perform an energy test on furnace...nice guy. We knew our attic was lacking in proper insulation so we decided to have them install additional insulation in the attic of our 50-yr-old house. Not an easy job in this tri-level home. Zach and Rob worked hard and fast. We've checked out the attic and it appears they have done an excellent job. Would definitely refer them to others. We now look forward to cooler summers and warmer winters. read more

We hired Premium Efficiency to a whole home inspection before buying our next home. We are beyond impressed with the quality of service provided by Zach. He is extremely thorough. We received an 80 page report for our home inspection that covered literally everything. He also used an infrared camera to help us check for any cool spots, potential leaks, or worrisome areas of the home. He checked for CO2 leakage from the gas appliances. He included an energy audit of the home and showed us areas of major potential improvement. Zach is extremely personable and was able to explain anything I had questions about. I've also spoken with Lyndsey in the front office, she is very knowledgable and whenever I've had questions has been able to get me an answer efficiently, and she is the sweetest woman ever! Their pricing was right on point and even better than some of the other competitors in the area. As we get ready to take this next step in our life, I wouldn't trust anyone else to come in and inspect our home. I would highly recommend their service to everyone i know. Call Zach and Lyndsey and you won't be disappointed! read more

I hired Premium Efficiency to do an energy audit who was recommended by a local utility company. Not only did he find a lot of energy loss, but I then had him come back to seal all the ducts in our home and later air seal the attic and under the floor and the final test results showed vast improvements in eliminating heat loss. He also installed baffles in the return air system to improve airflow throughout and after the work was done we noticed much better airflow through the ducts and the house warmed much more quickly. I was very impressed with his knowledge of the science in making a home more comfortable and would highly recommend Zach for anyone who needs his services. read more
