"We recently had York Home Performance complete an insulation upgrade at our home, and we couldn’t be happier with the results. From start to finish, their team was professional, knowledgeable, and incredibly efficient. Chris and Garnett were great. Chris took the time to evaluate our home's needs and walked us through the entire process so we knew exactly what to expect. One of the most impressive parts of the experience was how he helped us find excellent discounts that we didn’t even know were available. Thanks to his expertise, we were able to take advantage of local utility incentives that significantly reduced the overall cost—making the project extremely affordable. The quality of the insulation work itself was top-notch. Our home is noticeably more comfortable, and we know we will see a difference in our energy bills. It's rare to find a company that combines great workmanship with outstanding customer service and affordability, but York Home Performance delivered on all fronts"

Energy Efficiency Auditing questions, answered by experts

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

Audits typically take 2-4 hours, depending on the property size and energy systems.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.
