No one wants to worry about heat exhaustion in the middle of July. But if you don’t make sure your HVAC system is working properly, that is exactly what you’ll end up doing. 

Whole-house air and heating systems are a key way to keep your family happy and healthy. They allow you to keep the house at a steady temperature. The filter system also protects family members with asthma or other breathing problems.

An added bonus is HVAC systems allow you to keep your home closed up, making it harder for bugs and parasites to get inside to cause problems.

If your system doesn’t work properly, it may be time for a HVAC replacement. Here are a few signs that it’s time to replace your system.

Noisy System

As HVAC systems age, they naturally create more noise. Here are a few warning signs you need to watch out for that will determine if your HVAC’s time has come.

  • The blower gets louder with every season
  • A rattling or other noise when the air conditioner starts
  • Groaning and thumping from the furnace
  • The outside unit makes weird sounds

These noises could mean you need to call in a pro for a serious repair for things like a broken motor bearing or a slipped fan belt. At some point during the process, you may have to make the hard decision to skip the repair and just replace the whole thing, so be ready.

Leaks Around Your HVAC

These systems naturally create condensation when the air conditioner is running. What you need to look out for is excess water around your unit.

Sometimes the moisture you see isn’t actually water. If coolant is leaking from your AC, that’s a serious issue that needs to be addressed ASAP. Exposure to Freon, used in old units, can cause lung and organ damage. 

While leaking water doesn’t seem like too big a deal, it also needs to be taken care of immediately. Water damage around the unit will eventually find its way into your home.

If your HVAC is in a basement or attic crawlspace, this could lead to flooring damage. On top of that, excess water means the potential for mold production. 

No Air or Low Air Flow

No air flow generally means there’s something wrong with the compressor or that the coolant levels are low. Low coolant levels should be fixed ASAP because this could mean you have a leak. Low air flow could mean there’s any number of problems throughout your HVAC system ranging from a dying compressor to a punctured or blocked vent.

Either way, you’re looking at a lot of work just to check out the problem. If you have an older system, it might be wise to consider replacing the whole HVAC system.

One Room is Hot, Another is Freezing

Sometimes the wrong system gets put on a building before you move into it.

An HVAC unit that is too big will cool off the house too quickly. While this might seem like something good that will save energy, it only causes more problems.

Without the fresh air circulation, the system isn’t removing enough humidity. That humidity gathers in certain rooms, leaving them feeling hot and stuffy. Humidity also encourages mold growth in places like the laundry room, kitchen, and bathroom.

Your HVAC Runs Too Long

On the flipside, HVAC units that are too small for a home will cause it to run all the time. These systems just don’t have the power to keep a house under 79 degrees. It will end up costing you more in the long run to keep using a small unit than it would be to replace it.

Other problems that could increase the running time include a failing blower motor and bad coils. You should have a professional check for these problems, first. However, if this is a recurring problem, your best bet is to replace the entire HVAC unit with something you can trust.

Old and Unreliable

HVAC units have an average lifespan of 10 to 15 years. You might be able to stretch one or two more years beyond that if you do yearly maintenance on your entire system.

Clinging to old technology isn’t wise, though. As they age, HVAC units tend to require more frequent repair jobs. You wouldn’t want to be surprised with a busted system on the hottest day of the year.

Heat-related deaths totaled over 9,000 people over a 35-year span. Access to AC is the most reliable way to prevent heatstroke and shock from extreme dehydration.

Updating your HVAC system means access to better coolants, as well. Old Freon units can’t be adapted to new coolants which are more efficient at keeping the unit cool.

It is also a chance to make sure everything for your system is properly installed. Sometimes prior installers take shortcuts without keeping the best interests of the homeowner in mind. 

Rising Energy Costs

Summertime energy bills are things of nightmares. Add in the additional cost of running an inefficient air conditioner and it’s enough to make you yank out your hair. 

Your unit will naturally lose efficiency over time, up to 10%. This means it runs longer to get the job done. No matter how well you take care of your HVAC system by replacing filters, cleaning the ducts, and bringing in a professional to check it, it will eventually suffer corrosion and dirt build-up.
