"We had an outstanding experience with Holtzople Heating, Air Conditioning & Electrical Services thanks to the excellent work of Andrew and Jake. From the moment they arrived, they were professional, courteous, and clearly very knowledgeable. Andrew and Jake took the time to explain everything they were doing, answered all of our questions patiently, and worked efficiently to get the job done right. Their attention to detail and commitment to quality were obvious throughout the entire process. Our installation was seamless and we are very pleased. It’s not every day you find staff who combine technical skill with great customer service, but these two really delivered. It’s clear that Holtzople hires top-notch staff, and I wouldn’t hesitate to recommend their services to anyone. In fact, we are now repeat customers and have used Holtzople for additional services. Thanks again to Andrew and Jake for a job well done, and Holtzople for providing excellent products and services!"

Energy Efficiency Auditing questions, answered by experts

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
