Diagnosing what's happening in your house is the first step toward a comfortable and efficient home. Our certified professionals have been trained to conduct energy audits that employ scientific instruments, computerized analysis and reporting and practical recommendations to improve your home's comfort and efficiency. With your energy audit data in hand, we can review your home's specific needs, and the range of solutions that fit within your budget. Our experience with rebate programs for customers of FirstEnergy Utilities, Baltimore Gas and Electric and PPL Electric takes the hassle out of improving your home. We're ready to assist homeowners with insulation, air sealing, heating and cooling and home exterior upgrades.

"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

Installing weather stripping or upgrading to insulated panels can improve efficiency.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
