7 Major Signs That You Need an HVAC Repair

HVAC systems have been around since 1902 and can be found in most homes all across the country. These systems have made lives more comfortable and home more enjoyable all from the background. 

Even though they're so common, most people don't know much about them. That's typically fine until something goes wrong and you need HVAC repair. It's important to take care of problems as quick as possible to avoid an even bigger issue or the need for a total replacement. 

It can be difficult to know when your system is at the point that it needs repairs, so we've created a guide of the top seven signs it's time to call us to help you! 

1. Excess Noise 

No matter if you have a traditional HVAC system, a solo air conditioner, or industrial chillers you know what sounds they typically make as they run. Most systems aren't completely silent but aren't overly loud either. 

An easy way to know if you need HVAC repair work is if your system begins to make unusual noises as it's running. 

Sometimes a system will make a banging noise that could indicate a loose part. It can also be more of a whining noise that indicates belts aren't moving smooth. Most of the time when an unusual sound begins and then persists for a period of time, it's pretty obvious that something isn't working and needs to be repaired. 

2. Can't Regulate Temperature

The sole reason to have an HVAC system is to have the ability to regulate the temperature within your space, if it's not doing that the system needs to be looked at. 

Though it sounds obvious, this sign isn't always easy to recognize because the solution can easily be worked into your daily routine. So you have to pay close attention to catch when the temperature isn't regulating properly. The most common sign you'll see is that you're having to adjust your smart thermostats often.

Sometimes these issues can be due to improper maintenance, which is often an easy fix. But occasionally it's a bigger systemic issue. In cooling applications, a blocked evaporator coil or low refrigerat chargecan cause a lack of cooling. To easily determine if a unit has a blocked coil is to run a temperature differential before and after the coil. If you are not getting a temperature drop of at least 16 degrees Fahreneheit. If your unit is not achieving this, check for a blocked evaporator coil, and if all checks out then it is time to look at the refrigeration charge and components in the refrigeration circuit.

3. Inconsistent Areas 

Along the same lines, sometimes there begins to be areas in your home that become pockets for either hotter or colder air. The temperature isn't consistent throughout the home and that can be so frustrating!

When this happens, the first thing to check is to make sure the ventilation system is set up to avoid those pocket areas. This means all the vents are open and are pointed in a way that will fill the whole room with temperature-controlled air, instead of pointed in one direction. 

If those things are correct, then it might be a sign of a more serious problem and it's time to call in the professionals. 

4. Bad Smells 

When working right, a ventilation system should work in the background and be almost unnoticeable. So when you begin to notice unpleasant smells coming from your HVAC system, it's a good indicator that something is amiss. 

Truthfully, it can be difficult to nail down where a bad smell is coming from in a home. There are so many moving parts it could come from anywhere! But a bad HVAC system has some very distinct smells that are hard to miss. The main one is a burning smell that can come from bad parts. Other times it might be a more stale smell that comes from poor filtration. 

Whatever the smell is, it's good to have things checked out to make sure there's no danger. 

5. More Noticeable Dust

Often when you have that stale smell coming from your HVAC system it's accompanied by an excess of dust as well. You'll notice this dust on all of your major surfaces including the windowsills. 

A little bit of dust is normal for every home but when it becomes more than normal it can be a big problem. There are serious health risks that come from extended exposure to a lot of dust. So it's important to get your system cleaned up and repaired to avoid those. 

6. Increased Humidity 

Sometimes a broken HVAC system creates a more dry climate inside, causing excess dust. But sometimes it will go the other way and increase the humidity in your home. This generally happens when the problem is with the air conditioner. 

How air conditioners work is they run the air through an evaporator coil to cool the air down, this often produces condensation that is expelled out of the machine. When the whole machine and system aren't working right, that condensation can build up or leak and cause problems. 

Excess water is a pretty good indicator that it's time to call in a professional to get the job done correctly.  

7. Higher Bills 

Power bills fluctuate, especially between seasons. But the bills stay within an average range and can be predictable even with that fluctuation. If you get a bill that's significantly higher than normal, (without a reasonable explanation like an unusually hot summer), it's likely our to your HVAC system needs repairs. 

You can start by troubleshooting your HVAC system to see if you can figure out the problem. But if the problem isn't obvious you should call in a professional to avoid having to pay an unusually high bill again next month. 

When You Need HVAC Repair 

Once you've spent time without your HVAC system, you come to appreciate it even more. And you'll definitely be more vigilant in getting HCAC repair work done as soon as the issue is noticed. 

Paying attention to your system, performing maintenance, and getting issues check out quick will help keep your home comfortable and your system in tip-top shape for years to come. It's always better to err on the side of caution and bring in the professional than to wait and then be left without temperature regulation for a period of time.
