According to Energy Star, a home in Central PA should have a total R-Value, or resistance to heat, between R-49 and R-60. This would equate to about 16.5″ to 20″ of total blown-in insulation.

A Standard 1″ air filter should be changed at least every 3 months, even as soon as monthly during heavy use times and if there is a lot of activity from people or pets.

Hard water is not necessarily bad for you to drink but it can have adverse effects on hair and skin. Otherwise, it is harmful to your home’s plumbing and any water-using appliances, resulting in a decrease in their efficiency and useful life.

Seasonal Energy Efficiency Ratio or SEER, is a way to measure an air conditioner or heat pumps performance during the cooling season. The minimum SEER in Pennsylvania is 13 for A/C and 14 for heat pumps. When considering replacing either, the SEER is only part of the equation, even those minimums will be an improvement on many systems over 10 years old. So, don’t get overly hung-up on a SEER rating, consider all of the other features and benefits and how a system will perform for you and your home.
