In 2023, energy efficiency is something everyone tries to be conscious of. Reducing energy consumption has proven not only to save homeowners money but maintain the efficiency of your HVAC systems, is an important step to reducing harmful emissions into the environment. When it comes to your furnace, there are several indicators that homeowners should look out for to determine the efficiency of their heating system. At Morrison Plumbing in Caseyville, IL, we are proud to offer reliable furnace maintenance and repair services to ensure the maximum energy efficiency for your home. We’ve included the top 4 ways homeowners can tell if their furnace is – or is not – running efficiently. 

Fluctuations in Your Monthly Bill

When it comes to your monthly energy bill, fluctuations in price throughout the seasons are common. The longer you own your home, the more you can begin to predict just how much energy your HVAC systems are using year-round. When you notice odd increases in your heating bill, the first thing our technicians suggest is having your furnace inspected. Oftentimes, a lack of maintenance or a cleaning of your air ducts is the cause of an expensive heating bill. Luckily, these efficiency issues can be fixed by our team at Morrison Plumbing in Caseyville, IL. If you suspect that your high energy bills are caused by your furnace, give us a call right away.

Get An AFUE Rating

An AFUE, or Annualized Fuel Utilization Efficiency, rating is one of the most precise and accurate ways you can determine if your furnace is lacking energy efficiency. This scale is governed by the U.S. Department of Energy and can calculate the exact percentage of efficiency that your heating system runs on. At Morrison Plumbing, we have the technology and skill to provide AFUE ratings for your gas or electric furnace. This rating will let our team know just how much energy is being wasted converting your fuel into heat and what can be done to fix the problem. Oftentimes, these solutions include simple repairs or complete replacement of the unit. To get an AFUE rating on your furnace, schedule a service from our team in Caseyville, IL.

Consider the Age of Your Furnace

Even if your AFUE rating is fairly good, the age of your furnace can significantly impact the overall functionality of your heating system. Many furnaces, both gas or electric, are able to last anywhere from 15-20 years with consistent maintenance., If you haven’t had the filter replaced in over a year and haven’t paid much attention to the internal system for over a decade, the energy efficiency of your system will inevitably decline. When you call Morrison Plumbing in Caseyville, IL, be sure to educate our HVAC technician on the age of your furnace so that we can properly restore your heating system.

Conduct An Airtight Test

Airtight tests locate any possible drafts in your home coming from windows, doors, or vent openings that could be contributing to the efficiency of your HVAC systems. These simple tests are essential in determining whether the issues stem from your furnace or the construction of your home, both of which can be easily fixed. One of the easiest ways to locate drafts in your home is by standing close to your doors and windows and noticing any slight breeze or temperature difference. 

Unfortunately, many times sealing issues with your windows and doors can only be found using a blower door device. This powerful fan blows air out of your home to create a pressure difference that can detect even the smallest of seal leaks. If you’ve conducted an airtight test and have still noticed a lack of efficiency with your furnace, give Morrison Plumbing a call at (618) 408-1446 for an immediate inspection.
