7 Warning Signs Your HVAC Unit Is Going Bad and Needs To Be Repaired

Not sure if your HVAC needs to be repaired? Read our simple guide to seven common signs your heating and cooling system may need a repair. 

Most homeowners wait until their HVAC unit stops working to give it the attention it needs. This can mean going days without air conditioning and, even worse, a higher repair bill than regular maintenance would cost.

Recognizing when to call for HVAC repair isn’t common knowledge. The issue is not that homeowners want to put off repairs, but that they don’t know how to recognize the signals for maintenance.

We’ve made a list of seven common warning signs that indicate it’s time to get HVAC repairs done. Because we’re one of the oldest, most reputable air conditioning businesses in Augusta, you can rest easy knowing your HVAC system is in good hands with the comfort pros at Sig Cox.

1. Your Unit Constantly Runs but Doesn’t Cool or Heat Well

If your HVAC system runs constantly but fails to cool or heat your home well, it may be faulty. It may not need an emergency repair, but you should schedule an annual maintenance appointment to prevent more serious problems down the line. Problems with your thermostat are often to blame for systems that cycle often. 

2. You Hear Rattling or Grinding When the System
Turns On

Have you heard a rattling or grinding noise when your HVAC system turns on? If the sound is coming from inside the unit and not from outside, it’s time to schedule maintenance immediately. It could be something as simple as debris in the AC line. A maintenance visit can help prevent major problems later on.

3. The Air Ducts Near Your Home Are Dirty

If you see dirt and dust near your home’s air ducts, this could mean they’re clogged. You should hire an air conditioning contractor to inspect them and clean out any particles that may cause serious issues for your unit in the future. Cleaning them yourself could lead to larger problems if not done properly.

4. There’s a Strong Odor Near Your Unit

Another sign there may be a problem is a strong smell near the unit. This could be caused by an accumulation of mold, dirt, and bacteria. An air conditioning company should inspect this for you as soon as possible. If not dealt with right away, these particles could lead to serious health problems.

5. You’re Seeing Leaks or Water Puddles Around Your Unit

If you notice leaks around your HVAC system, this could indicate other issues like loose connections and faulty seals near your home. A leaky unit can cause serious damage to your house; it should be inspected immediately. If water puddles around the unit regularly or forms at its base, it may be time to replace your entire air conditioning unit.

6. A Change in Airflow

If you notice a marked change in your system’s airflow, be on alert. Changes in airflow often indicate something is wrong with your HVAC system, such as a clogged line. Don’t try to fix the problem yourself — this is an issue for a professional to diagnose and repair. 

7. Indoor Humidity

Another red flag to watch out for with a failing HVAC system is your indoor humidity levels. Increased humidity can indicate a problem with your HVAC unit. Whether it’s summer or winter, indoor humidity can be blamed on your HVAC system’s performance. Sticky, stuffy air is not only uncomfortable but also unhealthy! 

Call for an HVAC system inspection immediately.

Customer Reviews

best hvac company in Augusta
“I called 6 other companies when my AC stopped pushing air at 5PM. None of them seemed to want my business. When I got to Sig Cox, the guy who answered the phone was polite, knowledgeable, and was even trouble shooting with me before sending someone out. The agent got to my house in 30 minutes, troubleshoot, and fixed the problem in another 30. He even topped off the freon for free. The pricing was definitely agreeable. You’d get charged the same or more with any other company. Some of the best customer service I have seen. You should absolutely consider Sig Cox for you HVAC problems, I won’t be looking anywhere else.”

“These people are amazing. After hiring Sig Cox the first time to fix my HVAC unit about a year ago, I was more than happy, to say the least. Then about a week ago I had them install a new HVAC unit for me. This is by far the best a/c repair company in Augusta GA. They are professional, timely, and really take care of their customers. I highly recommend them and proudly give them an A+ rating! Thank you all so much!”

“This company did some work for my mother-in-law, of which she was quite pleased, so she recommended them to us. We had a downstairs unit that just wasn’t putting out any cool air. They came by post haste and assessed the unit, gratis. Of course it was a compressor failure so we had to make the hard decision to buy a new unit or fix what we had. The advice we got from our man on the scene was honest and sincere.
Since we had an older unit that used the phased out Freon and compressors are ugh, expensive, we went with a new unit. We decided on the Amana since it had a lifetime warranty on the compressor and rated well in Consumer Reports.
A month later the other unit failed and we replaced that as well. Six Cog worked with us on the price, we were never hassled on the payment, nor did they demand any payment on the spot and never did I feel pressured into anything. The install was smooth, fast and highly professional. Both units fired up, granted a month apart, and the house was cool almost immediately.
This company has a great reputation from what I can garner in the community, and I’m here to tell you that I recommend them highly as well. Please note that this is first recommendation I have ever put online.”

My air conditiong system went out, Sig Cox was recommended so I called them. Technician Andrew came out, was on time, and he properly diagnosed the problem. He had the part ordered. When the part came in, Nolan installed the part perfectly. Both technicians were very professional and knowledgeable. I even talked to the owner of the company who is involve day-to-day with his company. Very nice people to deal and they really go beyond what’s expected to help you get things fixed. I highly recommend Sig Cox!! Ask for Andrew or Nolan, they know what they’re doing!!

We have been SO impressed with everyone we have worked with, from the customer service, to the salesman, to the technicians, they are all so friendly and professional! We will be loyal customers from now on!”
