Can a dirty air filter cause a high electric bill?

• <div><p>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 <a href="https://www.energy.gov/energysaver/maintaining-your-air-conditioner#:~:text=Replacing%20a%20dirty%2C%20clogged%20filter,in%20the%20air%20conditioner%20itself.">U.S. Department of Energy</a>, replacing dirty filters can save you between 5% and 15% in utility costs.</p></div>

• <div><p>Yes, with features like LED lighting and variable speed controls for efficiency.</p></div>

Q: How can a heat pump improve my home's energy efficiency?

• <div><p>Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.</p></div>

Q: What is R-value?

• <div><p>R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.</p></div>
