The HVAC system in your Lake Forest, Illinois, home was designed to last for many years. Yet, over time, through wear and tear and heavy use, your system may begin to function less efficiently or may require more frequent repairs. If your HVAC system begins exhibiting any of the signs and symptoms listed below, it may be time to consider replacing it.

Your System is Older Than 10 Years

HVAC systems were designed to last between 10 and 15 years before needing to be replaced. Once your system has reached the 10-year mark, you may be noticing more parts are worn and in need of replacement and you also may be seeing signs of inefficiency. Even if you have maintained your system well, odds are your system still uses the refrigerant known as R-22. This substance has now been deemed dangerous to the environment and is being phased out. A new system will use the upgraded refrigerant system and will be safer for your home as well as the environment.

Your Repair Costs Have Exceeded Half the Cost to Replace It

Normal repair costs are a part of maintaining the health of any system. But repeated and costly repairs can be a signal that the system is no longer working as effectively as it should be. If you are unsure how to weigh the costs of repairing your old system versus replacing it with a new one, a good rule of thumb to follow is the "50 percent rule." If the repairs required to get your system up and running properly are higher than half the cost to install a new system, a replacement is the better investment.

Your Energy Bills Keep Rising

Your energy bills will go through typical seasonal changes with higher costs during cold or hotter months. But these bills should remain on a similar cycle year after year. If you notice these costs are beginning to get higher than normal, odds are your system is working less efficiently than it should be. Your system could be losing efficiency due to age, lack of maintenance, or worn parts.

You Can No Longer Keep a Comfortable Temperature

As your HVAC system begins to age and lose its efficiency, it may have to work harder than normal to be able to maintain a consistent temperature in your home. This also can occur due to low refrigerant levels, clogged filters, cracked ducts, or even more severe damage such as bad motors in the system. Being unable to keep the temperature comfortable could also be a sign that the system is no longer powerful enough to heat and cool the size of your home. Installing a new system will ensure you have the power you need and help you save on energy bills.

You Have an Increasing Amount of Dust in the Home

Not only does your HVAC system maintain the temperature in your home, it also provides you with proper air ventilation. If your system is running at its peak efficiency, it will improve the quality of the air inside your home by removing dust, dander, dirt, and debris. If you have noticed an increased amount of dust throughout your home, your system may no longer be working properly enough to remove it.

Your System Emits Odd Sounds or Smells

Aside from the normal sound of the machine starting, your HVAC system should operate relatively quiet throughout the day. As the system and parts get older, you may notice them beginning to make noises such as squeaking and grinding. Any unusual noises could signify a pressing problem and should be checked. In addition to odd sounds, you should also be concerned with unusual smells aside from the mild burning smell when you start up your heat after it has been unused for a while. Constant burning smells can signify a deeper problem such as melted wiring and may be a sign that your HVAC system should be replaced.

If you notice any of the signs and symptoms above, there is a good chance it may be time to consider installing a new unit. To find the best unit to fit your heating and cooling needs, contact the HVAC specialists at Ireland Heating & Air Conditioning at 847-388-0108.
