The technology in the HVAC field has improved a lot over the years and has become highly efficient in terms of energy conservation. According to the U.S. Department of Energy, if you switch to an energy-efficient air conditioner in the summer, you could reduce your AC energy usage by 20% to 50%. If you've been considering replacing your HVAC system, but you're unsure whether now is the right time to do so, here are some key signs to be on the lookout for.

Your Unit Is More Than 10 Years Old

While these units can last a while with proper maintenance, Forbes reports that it may be a good idea to consider replacing your HVAC system if it's approaching the 10-year mark. Old HVAC systems often need to work harder to produce the same results as a newer system, which can negatively impact their energy efficiency.

Your Unit Isn't Blowing the Proper Type of Air

If your HVAC system is blowing cool air when you have the heat on or warm air when you have the air conditioner running, you want to have a professional come look at it. An HVAC professional can determine if the problem has to do with the compressor, refrigerant, or something else entirely. They can also help you determine if now is the right time for an HVAC replacement.

Your Unit Has Poor Air Flow

If you turn on your HVAC system and you feel like you'd get better results by fanning yourself or by putting on a sweater, then it may be time to replace your unit. Contact your local HVAC services to inspect your system. They might determine that you have an issue with a clogged air filter, or there could be serious issues with the motor or the fan.

Your Unit Makes Loud Noises

Your HVAC system should run fairly smoothly without much noise. It should become a welcome background sound that you can soon tune out. If you find that it's starting to make loud noises, then it can mean there's a loose part or that something's broken. Don't wait for the noise to go away on its own. Have someone come take a look at it and repair your system if necessary. In some cases, it may be more cost-effective to completely replace the unit depending on the age of your system or the amount of damage that needs repair.

Your Unit Is Increasing Your Indoor Humidity

If you notice that your home has become more humid lately and you haven't added a humidifier, then you need to have your HVAC system looked at by an expert because increased humidity can indicate major issues. While a repair may be able to fix your unit, it may be in your best interest to replace the system. Units that are too large for the property can often cause increased humidity as well as short-cycling.

Your Unit Produces Foul Odors

You shouldn't have to hold your nose if you walk near your HVAC system. The air that comes from it should be clean. If you do notice that the air smells musty, then that can mean mold is in your unit, which can create respiratory issues like coughs and other things. Have your HVAC service take a look at your system to determine if remediation is possible or if the unit needs to be completely replaced.

You need to be vigilant when it comes to what's going on with your HVAC system. With proper maintenance, you can keep your system running efficiently throughout the year and prevent unplanned system failures that could not only lead to uncomfortable days but may also put your well-being at risk. What's more, by paying close attention to your HVAC system, you can keep yourself from being surprised when your system needs to be replaced, so you can better prepare for budgeting for a new unit.
