We are independent energy consultants who reduced our own energy use and saved several hundreds of dollars monthly on our utility bill and made our homes more comfortable and now are helping others achieve similar results. We are not contractors. We do not get paid based on the recommendations we make or the recommendations you choose to do. We want to provide you with what you need to do, explain why you need to do it so that you have all the information you need to make an informed decision. Once you've made the decision on what you want to do, after having all the information necessary to make an informed decision, we will help you implement your decision. We have vetted many home performance contractors and we know they will do the quality work you want and deserve. There are PGE rebates available and financing available that we will show you how to leverage to your advantage. So give us a try. You'll be glad you did.

We provide specialized testing for thermal imaging, EMF/RF, Mycotoxins, ERMI, VOC, allergens, bacteria, and other indoor air quality environmental issues. As part of our mold sampling process, we specialize in the utilization of an EPA-developed research testing tool, the Environmental Relative Mold Index (ERMI), when it is prescribed by an environmental medical physician/professional. We are nationally and statewide certified, experienced, fully bonded, and insured to meet your inspection and mold/environmental testing needs. As nationally certified mold and property inspection experts, we personally provide all field services, and as a result, are able to maintain the highest BBB, Home Advisor, Yelp, and Angie’s List ratings.

"Overall experience Terrific. Joseph is one of the most honest, straight forward guys out there. I am very thankful with God that he leasing me in the right way so that I would choose his company over the other companies out there. I’m the beginning I thought that the price was a bit high for my budget but then later I realized the skill level that he does in each one of his kinds of inspection he offers is unbelievable. I owe Joseph my life he helped me convince myself that there truly was a serious mold problem with the house that I just bought not even 1 year ago. So I moved out from my new home in the mean time before my health continues to get in more delicate situation. The mold odor has now begun to cause me to have asthma which I never ever had before in my life. The bank/ realtor Home inspection report of the home never caught any of this bad mal fowl odor and mold infestation from underneath the home. It’s crazy how some of these home inspection still are able to keep their business license when they are worth no good at all. Trust me you won’t regret yourself by choose Guaranteed Property and Mold Inspections. They are by far the best out there. They provided me with a very detailed reports which has lab results from samples they sent out and everything."

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

Energy Efficiency Auditing questions, answered by experts

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.
