How to Test for Fan Efficiency and Fan Watt Draw
As our electronics and other systems have become more and more demanding of power in relatively smaller and smaller spaces, fans have had to step up and draw upon all of their power in order to pull heat away from areas where it can build up. In home construction, forced air heating is often used to help keep the indoor temperature stable, but the power needed for the fan watt draw goes up accordingly as the fan's performance does.
More and more, with an eye on minimizing power consumption and increasing energy efficiency, fan load has become one of the areas of concentration. HERS-rated technicians must not only know how to check for air tightness in duct work or by using a door blower test, but must also be aware of fan efficiency and how it affects airflow and noise.
How Fan Efficiency Works
Fan manufacturers measure efficiency of their hardware using total pressure, while static efficiency is calculated by using static pressure. As air moves through a system, it creates positive static pressure. Any other components that inhibit the movement of the air flow create negative static pressure. Different types of fans therefore create different values of airflow in order to balance the negative and the positive.
Proposed Changes in Fan Efficiency
The California Energy Commission has proposed a new change in their codes and standards that affects single family and multi-family buildings. This proposal reduces fan unit efficiency from 0.58 watts per cubic feet per minute to 0.45 W/cfm In addition, it also allows for a compliance option for fault detection and diagnosis devices, This compliance credit for FDD devices will be designed to support long term and initial performance of cooling systems.
An alternative option would be to verify fan efficiency via temperature split. This alternative to refrigerant charge verification can still measure the performance of the system while detecting multiple system faults while needing less time to verify them.
Measuring Fan Watt Draw
If you're concerned that your fan installation is drawing too much wattage or you need to check for compliance, contact Poppy Energy. Our certified HERS-rated technicians can perform a variety of tests to measure the efficiency and output of your fan and HVAC system. We can also conduct duct airflow testing, door blower tests, and other testing and verification needed to obtain Title 24 compliance in order to secure a building permit or for other regulation needs.

What a great experience!
WOW, I got my compliance report within 2 days with an explanation of the important parts of the report and how it affects my new house. Since this report was registered, I submitted the Title 24 report and my plans with Sacramento County. No issues there. Paul also stated that they offer QII (Quality Insulation Inspection) that was needed right after the rough in stage stage. Lana came out and did an awesome job with the inspection and made a correction notice for the insulation company to return and fix part of the insulation.
Had a very positive experience and would highly recommend Poppy Energy for your new house, ADU or addition.
Grace K., Residential Home OwnerGranite Bay, CA

Antonio D., Project ManagerSacramento, CA
The team outmatched my expectations
I contacted Poppy Energy on the recommendation of a previous client. After several issues with other HERS raters, I was a bit skeptical but working Poppy Energy changed my perspective. The team outmatched my expectations. The HVAC Unit for the building was inspected and Quality Insulation Inspection done within time and budget.
Christopher K., New Construction DeveloperSacramento, CA
At Poppy Energy, every customer counts
I switched to Poppy Energy about three months ago and I must commend the outstanding staff and quality service I’ve received in such a short while for our projects. At Poppy Energy, every customer counts.

Honest, transparent and professional!
The entire airflow system of my 30-year home was overhauled and needed to certify the job. Poppy energy had recently done the same for a friend so I contacted them. From the first conversation to final inspection, I love the fact that there was a system of adequate feedback every step of the way. Honest, transparent and professional!
Duke G., Home OwnerFair Oaks, CA
Kudos to a great team
I knew absolutely nothing about the process of getting a Title 24 report compliance report for my building addition, plus I am not so tech savvy but a phone call with Paul put my mind at rest. He was friendly, attentive and quick to explain the process to me. He was just a call away if I had any questions. My report was completed in a few days. Thank you Paul, you are the best! Kudos to a great team and a job done well and on time.
Janet J., Project ManagerRoseville, CA
Highly Impressed
Absolutely the best technical company I have ever experienced! I often do not give reviews but I am highly impressed. I had to reschedule the appointment on such a very short notice but the team was willing to oblige me and even tried to fit in to my schedule
Francis B., Residential Home OwnerRancho Cordova, CA
Made a New Friend
I’m amazed at how quick and smooth the whole process went. My AC was replaced and needed a quality inspection, so I placed a call. Lana showed up at our door about an hour later, discovered the challenge and had it fixed in no time. I enjoyed a great conversation and made a new friend. Poppy energy came highly recommended from a neighbor. I’ll do well to pass on the recommendation as well.
Loretta M., Home OwnerGold River, CA
Showed up within 2 hours
I just had my baby a few weeks back and then my AC unit picked the worst time to fail. After a full HVAC replacement, we needed a full duct test and refrigerant test. I’m especially thankful for the prompt response on a week day though it came in as an emergency. The technician showed up within 2 hours after and did the duct test and refrigerant check in about an hour. Thank you again Lana!
Jamie T., BuilderWest Sacramento, CA
Excellent value for your money
After incurring more financial costs from several retests, Poppy Energy came through and helped us achieve an energy-efficient building at a relatively affordable cost. Poppy energy helped to carry out a Blower’s door tests for one of the building projects I worked on recently. I look forward to working on more projects with them and I will definitely recommend them to others. You are sure to get excellent value for your money.
Reed C., Project ManagerEl Dorado, CA
Keep up the good work!
Paul from Poppy Energy came to do a routine maintenance check on the heat system and AC system of some service apartments. He not only did an excellent job but also recommended additional ways of extending the life of the HVAC equipment. This advice showed he had our best interest at heart. Keep up the good work!
Patricia H., Home OwnerFolsom, CA
Best HERS raters
They are thus far, the best HERS raters I’ve worked with on any building. After the HVAC was fully installed in the building, the HERS Rater by the name Lana did a thorough job checking through air leakages, improper insulation, energy efficiency and other criteria. The house is declared fit just in time for my parents to move in. A great deal of professionalism and courtesy displayed.
Collins O., BuilderCarmichael, CA
Game-changer
I’ve been a customer at Poppy Energy for 6 months now. It’s been quite difficult finding a good HVAC HERS and Duct testing company that I could always count on to deliver all the time. I want to say a huge thank you to the team at Poppy Energy, for being consistent, awesome, dedicated and extremely diligent at their craft. Your excellent and timely service is a game-changer
Sonia, P., Project ManagerLoomis, CA
Efficient, Very Thorough and Professional
I moved in newly to California about half a year back and starting a new building project that required that I carried out a Quality Insulation inspection. I found Poppy Energy as a certified HERS Rater on the CalCert website and booked an appointment with them. They were efficient, very thorough and professional. I will not be using any other HERS Rater any time soon and I will definitely tell my developer friends about Poppy Energy
John M., Home OwnerAntelope, CA
Very Good at What They Do
I’ve used Poppy Energy for my Duct test to my HERS testing to fix an air flow leakage challenge once I found out it was much colder in the attic than inside my home when the AC was on. I must say without bias that they are very good at what they do. The company is great and its employees are always courteous, always willing to help. Thus far, I’ve not had any challenge with their work. Their response time is great and the pricing quite fair. The technicians always take time to troubleshoot, and also explain the cause of repair if need be. I’ll highly recommend them.
Timothy R., BuilderRocklin, CA
Huge Thumbs Up For Poppy Energy
The personnel who came in to carry out the pressure test on my new forced air heating system duly observed strict Covid protocols. He was very efficient, has a sound knowledge of his craft and also very reassuring. A very huge thumb up for Poppy Energy! You are the best.
Steve K., First Home BuilderPenryn, CA
Definitely Recommend
HERS Testing, Title 24 compliance, & CF1R reports all sound like a foreign language to me but this group seems to know their stuff. They don’t seem to mind taking their time to walk you through things and they always seemed to be available when I needed them. I would definitely recommend them without question. Thanks for your help guys. I appreciate it.
Cleveland R., HomeownerAuburn, CA
A++++ service
I couldn’t be happier with the service I received from them. They made sure to complete the duct leakage test quickly and what seemed to be very efficient. I feel a lot better knowing that everything has been brought up to the level it should be. When it comes to peace of mind the cost is priceless. A++++ service.
Robert S., First Home BuilderLoomis, CA
Big Thanks From Me
When dealing with new construction make sure everything is being inspected properly. When I called Poppy Energy, they made sure I understood all the details of what needed to be tested and make sure everything in the house was compliant. I can’t imagine the nightmares that could have happened if they weren’t there to make sure my house was safe, sound, and working properly. They get a big thanks from me.
Kyle B., Home BuyerFolsom, CA
Save You Money in the Long Run
When you buy an older house there are always unforeseen problems. Having this 1960’s ranch house had a lot more issues than you would think for a house that isn’t nearly as old as my grandparents. But when you fall in love with the house you gotta be careful of all the little missteps. Having a quality insulation inspection is paramount to find out where and how warm air or cool air are leaking out of your house. Do yourself a favor and make an appointment sooner than later. It will save you more money in the long run.
Tanya F., ArchitectWoodland, CA
Top-Notch QII for Our Green Building Project
We're building a net-zero energy home in Davis and needed a HERS rater who truly understood the importance of insulation quality for energy performance. Poppy Energy's QII inspection was meticulous. Their inspector used thermal imaging alongside the visual inspection and documented everything with detailed notes. They caught air gaps around electrical boxes that would have hurt our blower door results later. If you care about building performance, Poppy Energy is the team to call for your QII.
Angela M., Home OwnerGrass Valley, CA
Made the Permit Process So Much Easier
Getting our home addition permitted in Rocklin required a QII inspection and I had no idea where to start. Poppy Energy walked me through the entire process from scheduling to what to expect during the inspection. Their inspector was friendly and efficient, completing everything in under an hour. The report was submitted to the building department electronically and we got our sign-off the same week. Could not have been easier.
Kevin N., General ContractorLoomis, CA
Consistent Quality Across All Our Projects
We've been using Poppy Energy for Quality Insulation Inspections on all of our new construction projects in Placer County for the past two years. Whether it's a single-family custom home or a 30-unit multi-family build, the quality and consistency of their QII inspections is always outstanding. Their reports are detailed with photos and they always flag issues before they become problems. A builder's best friend during the insulation phase.
Samantha H., Home OwnerPenryn, CA
Reliable QII for Our ADU Project
We built an accessory dwelling unit in our backyard in Elk Grove and needed a Quality Insulation Inspection before closing up the walls. Poppy Energy came out the next morning and their inspector was fantastic. He was patient, explained everything to us as homeowners, and even helped us understand why proper insulation matters for energy efficiency and comfort. The whole process was smooth and affordable. Five stars all the way.
Carlos R., Insulation ContractorSacramento, CA
Helped Our Insulation Crew Improve
Poppy Energy didn't just inspect our insulation — they educated our crew on best practices for QII compliance. Their inspector took the time to show our guys exactly how to properly fill wall cavities and seal around penetrations. Since working with Poppy Energy on QII, our first-pass rate has gone from about 70% to nearly 100%. They've made our whole team better at what we do.
Brian P., DeveloperLong Beach, CA
Great Value for Multi-Home Developments
We contracted Poppy Energy for QII inspections across a 45-lot subdivision in Sacramento. Their pricing was very competitive and they were able to inspect multiple homes in a single visit, which kept our project on schedule. The inspectors were always courteous and worked well alongside our insulation crews. The digital reports were clear and easy to share with the building department. Best QII provider we've used in the Sacramento Valley.
David W., Construction SuperintendentYuba City, CA
QII Experts Who Know the Code Inside and Out
I've worked with several HERS raters over the years and Poppy Energy is by far the most knowledgeable when it comes to Quality Insulation Inspection requirements. Their inspector explained every aspect of the California Title 24 insulation standards to my crew and helped us understand exactly what passes and what doesn't. We've now completed three subdivisions with them and have never had a single failed inspection. True professionals.
Rachel K., Home BuilderRocklin, CA
Fast Scheduling and Excellent Communication
As a custom home builder in El Dorado Hills, I need HERS raters who can work around tight construction schedules. Poppy Energy scheduled our QII inspection within 48 hours of my call and the inspector arrived right on time. She walked through the entire house with my insulation sub, pointed out areas that needed correction, and even took photos for our records. The communication throughout was top-notch. Will definitely use them on every future project.
Jennifer L., Project ManagerSan Bernardino, CA
Saved Us from a Costly Mistake
We hired Poppy Energy for a QII inspection on our 12-unit townhome development in Roseville. Their inspector caught that the insulation contractor had used the wrong R-value batts in several units before the drywall went up. That catch alone saved us thousands in potential rework. The report was detailed and delivered the same day. Outstanding quality insulation inspection service from start to finish.
Marcus T., General ContractorFair Oaks, CA
Thorough and Professional QII
Poppy Energy performed a Quality Insulation Inspection on our new construction home in Folsom. The inspector was incredibly thorough, checking every wall cavity and attic space for proper insulation coverage. He identified a few spots that the insulation crew had missed and got them corrected on the same visit. We passed on the first try thanks to their attention to detail. Highly recommend for any builder needing QII services.
