How Do I Know If My HVAC Unit is Energy Efficient?

When it comes to energy efficiency, your HVAC unit can be the difference between a comfortable, efficient home and one that wastes energy. How do you know if your system is up to standard? At Rooter Hero Plumbing & Air, we help local property owners improve the condition of their heating and cooling systems. Whether you need a new installation or an air conditioning repair, it's important to hire an HVAC company that will put your needs first. Our technicians can offer solutions to your high energy costs. If you're unsure whether your HVAC system is wasting energy, this guide will help you find the answer.

The Most Common Signs of an Inefficient HVAC System

If you're having problems with your home's central air conditioning system, it could be for various reasons. The first step in determining the issue is to identify the most common signs of an inefficient HVAC system. Here are a few to look for:

  • Noisy Operation
  • High Energy Bills
  • Short Run Times
  • Poor Air Quality
  • Frequent Repairs and Maintenance

Seasonal Energy Efficiency Ratio (SEER)

The SEER rating of your HVAC unit is a measure of its efficiency. It tells you how much energy your AC unit uses to cool the air inside your home. The higher the SEER rating, the more efficient your system will be. Lower SEER ratings may use more energy than higher ones because they're less effective. In the U.S., today's air conditioners typically have a SEER rating of between 13 and 22. Comparatively, if your AC unit is old, it probably has a SEER rating of 8 or 9.

Energy Star Certification

If your HVAC unit has an Energy Star certification, it's been put through rigorous testing to ensure that it meets certain efficiency standards set by the Environmental Protection Agency (EPA). You can find the Energy Star certification on your unit by looking at the side of the unit. You should see an energy rating, which will be a number between 1 and 100. The higher the number is, the more efficient your unit is. If you don't see this symbol anywhere on or near your HVAC equipment, then there's a good chance it doesn't qualify for certification.

AFUE Rating

The AFUE, or Annual Fuel Utilization Efficiency, is used to evaluate the ability of furnaces and boilers to produce heat from fuel. You won't see this rating on equipment labels because it's determined by many factors that could be affected by weather conditions and installation practices. The higher the AFUE rating, the more efficiently your unit delivers heat.

Do You Need to Replace Your Old HVAC System?

If you're looking to buy a new HVAC system, it's vital that you hire the right HVAC company in Rio Linda for the job. Our technicians provide professional air conditioning repair, heater installation, and HVAC replacement services for local homeowners and businesses. Call Rooter Hero Plumbing & Air for more information about how we can help you stay comfortable while spending less on utility costs.
