Signs It Is Time For HVAC Replacement
Besides the above considerations, certain telltale signs will indicate when your system needs an upgrade. Replacing your HVAC unit before further damage can accumulate is essential to maintain comfortable temperatures in your home. By keeping an eye out for these signs, you can tell when your HVAC system needs a replacement:
Your HVAC unit heats and cools your home while also providing ventilation. An efficient HVAC system can improve your home’s air quality through the elimination of dust, debris, dirt, and pet dander. It can also keep humidity down inside your home. If you notice an increase in dust in your home and higher humidity levels, this indicates your HVAC unit isn’t efficient enough to eliminate airborne particles, and it may be time for a complete replacement.
Your HVAC unit shouldn’t make much noise during a normal cycle. However, as your system ages, you may begin to hear strange sounds like squealing or grinding. If your well-maintained HVAC unit is starting to make strange or loud noises, it is important to call a technician right away, as this may be an indication of a more significant problem and could require a complete HVAC replacement.
Similarly to strange sounds, if you begin to smell something odd or unusual from your HVAC unit, there could be many causes. While it could simply be the smell of dust burning off of your system, it could also indicate mold in your ducts or melting components. It’s best to contact a professional HVAC technician to determine the cause of the smell and they can then let you know if the damage is extensive enough for you to begin to consider a replacement.
Rising energy bills can be frustrating, especially when they increase without any change in the usage of your HVAC system. Over time, your HVAC system decreases in efficiency and loses the ability to heat and cool your home correctly. If your energy bill is increasing compared to prior years, this can be a common indication of a less efficient HVAC system that may need replacement.
If you find it challenging to regulate the temperature in your home, it could mean that you either have an incorrectly sized or improperly functioning unit for your home or an aging HVAC system that is decreasing in efficiency. As your HVAC system ages, you may notice a natural decrease in its ability to maintain a consistent temperature in your home. While there are many reasons for this, you may want to consider a replacement to keep your energy costs low and your home comfortable.
R-22 refrigerant has been phased out by the EPA over time due to its harmful impact on the ozone layer when released into the air. Although many HVAC systems still use R-22 refrigerant today, acquiring it for repairs has become costly and difficult. It may prove more cost beneficial to upgrade your old R-22 HVAC unit to a modern one without any harmful chemicals.
