"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.
