We understand you often have questions about the various systems in your home. Here are the answers to some of the questions our Armstrong plumbers, electricians, and HVAC technicians often hear in the course of their day.
First, let us just say, “good job!” Everyone should want to learn more about their HVAC filters because they are very important. According to the Department of Energy website, replacing filters is the single most important HVAC maintenance task. Clean filters can reduce energy consumption by up to 15%.Armstrong understands choosing the right filter can be confusing. The best way to compare is with what’s called the MERV rating, which stands for minimum efficiency reporting value. The scale goes from 1 to 16. The higher the rating, the more and smaller particles the filter can stop. But on some systems, a filter that’s too dense can restrict air flow too much.
Fiberglass or pleated filters are most common. Armstrong recommends a more sophisticated purification and filtration system from Lennox or Aprilaire, especially if there are people in the house who suffer from allergies and asthma.Close It Up ↑
