"I am in the process of selling my home, and the home inspection called for further evaluation of my AC and Furnace. The furnace did need to be replaced, but they issued a horrible evaluation of a 10 year old functional AC, saying that, "Inspect A/C found condenser coils smashed beyond repair. Checked refrigerant and found unit almost dry." I had a second inspection done on the AC soon after, and the inspector said that those comments were a gross exaggeration. The AC while 10 years old, was functionally fine, but needed 2 lbs of R22 added."

"Everything about Paul and Mindy Peterson and their son Anthony is professional and well done. Mindy came out and gave a thorough report with pictures, never a hard sell. I went with the medium option (not the most expensive with all the bells and whistles and did not go with the basic). She was informative and honest. A family owned local business who works really hard at the integrity of the business. Anthony arrived and so impressed with how they were concerned with the respect of my home. They draped the floors with painters cloth and super duper careful on walls, doors, etc. The job was completed in timely manner and if I had any issues - which I don't , they are the kind of people who want to make it right and would come back in a heartbeat. They are great people and in today's world, it is really hard to find ethical suppliers who also care about the customer. Job well done and HIGHLY recommend. Look no further, they are the real deal."

FAQs for home energy audit projects in Saint-Louis, MO

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
