Want to Optimize Furnace AFUE? Improve the Efficiency of Your Cincinnati Home

Your furnace's AFUE is not set in stone. It is representative of the Annual Fuel Utilization Efficiency your furnace or boiler can achieve, assuming the conditions are right and that your HVAC equipment is inspected and maintained on a regular basis.
Consider that a furnace with an AFUE of 90 percent cannot possibly function at that level if air leaks allow warmed air to escape right out of your home, or inadequate insulation is unable to mitigate energy-wasting heat transfer. Before you invest in a replacement furnace with an noteworthy AFUE, make sure your home's additional energy systems are in good shape.
Seal the air leaks. Take the time to seal any noticeable air leaks in your home. If you have the time and budget, you may want to consider having a professional energy audit performed. If not, inexpensive caulking and weatherstripping will go a long way towards sealing your home's envelope. Inspect the exterior walls of your home for any visible cracks, gaps or holes and seal them up. Pay extra attention to the areas where siding meets the roof and foundation, and where the exterior wall is penetrated by electrical and plumbing work. Replace any worn weatherstripping around doors and windows.
Upgrade insulation. Insulation does not stop air from flowing from one place to another, but it does mitigate heat transfer. If you live in an older home, there is a good chance the insulation is not up to current energy standards. Check to make sure the insulation in your attic, crawl spaces and exterior walls complies with the Energy Star Recommended Levels of Insulation, Cincinnati is located in Zone 4. If you can't afford a whole-home insulation upgrade, start with the attic and work from there.
Replace your windows. Windows are one of the largest sources of heat loss in the home. If you have older windows, create a plan to begin replacing them with energy efficient counterparts.
