Do you know the signs of a failing A/C unit? This summer, make sure you’re paying attention to changes in your air conditioning or home environment. When you’re attuned to your cooling system, you can catch trouble before it starts. Ignoring issues can lead to more expensive repairs in the future. Here are a few signs your air conditioning may be headed for trouble and needs repair by professionals.
1. Your Air Feels Warm Instead of Cool
Are you noticing the temperature in your home seems to be increasing despite running your air conditioning? This could be a sign your system is struggling.
Potential Causes
- The outdoor unit may need professional cleaning
- Your unit may have a refrigerant leak
- Your compressor is failing
Why You Need a Pro to Fix It
The compressor is an expensive part of your system and requires special skills and tools to correctly diagnose and repair the issue. Trying DIY methods could cause additional damage.
Refrigerant is a chemical that needs to be handled properly to ensure safety. EPA Section 608 requires those that work with refrigerants to be properly licensed. A licensed professional can check for leaks and seal them. This is important to prevent the refrigerant from escaping and contaminating your home or the environment.
2. Your Airflow is Weak or Inconsistent
Have you noticed air isn’t pumping through the house the way it used to? When you put your hand over the vent does it seem to barely push through?
DIY scheduled air filter changes will address many low air flow problems before they start. But after changing the air filter, if the airflow is still weak, the indoor unit needs a checkup.
Potential Causes
- Air filter is plugged
- Malfunctioning blower motor
- Ductwork leaks
Why You Need a Pro to Fix It
If a plugged air filter is left installed, air will pass around it instead of through it allowing materials to collect on the inside of your indoor unit. Some areas that need to be cleaned are not easily accessible and internal components may need to be removed for access to them.
The blower motor requires proper diagnosis, tools, and experience with electrical components. Professional HVAC technicians have acquired the skills to safely fix blower motor issues. Additionally, trying to fix your own blower motor could void your warranty.
Ductwork leaks could be difficult to locate and need to be sealed properly. If the leak is between the air filter and indoor unit, materials may collect inside it. If you try to DIY the sealing, it may not last as long as a professional who uses the correct products and understands the application process. Also, duct leaks may be located in difficult to reach locations in your home. For your own safety, let the pros do the work.
3. Your Unit Is Making Strange Noises or Producing Weird Smells
Pay attention to your system, indoors and out. Does it sound differently than normal? Are you noticing weird smells following out of vents? Something is definitely off with your unit.
Potential Causes
- There are a number of potential causes for strange noises including: fan motor issues, failing bearings, clogged filters, parts breaking down, compressor problems…the list goes on.
- Unusual smells can stem from: mold, mildew, electrical issues, clogged drains, and dirty air filters.
Why You Need a Pro to Fix It
Because of the variety of potential causes for these symptoms, you need a heating and cooling expert to identify the culprit. The pros come with experience diagnosing issues, the correct tools to pinpoint the problem, and an understanding of how to safely address complex systems.
4. It’s Humid and Damp in Your Home
Are you noticing a sticky feeling in the air at home? This is a sign moisture may be taking over your environment. Other signs of high humidity include: condensation on windows, mold or mildew growth, musty smells, or warped wood and paint. Humidity can damage your health and home, so it’s time to address it.
Potential Causes
- Dirty evaporator coils
- Leaking refrigerant
- Wrong sized A/C unit for home
Why You Need a Pro to Fix It
Once again, there are so many potential causes for this issue. While you can change a clogged air filter, you should not touch the evaporator coil or mess with refrigerant in your system for safety reasons. Heating and cooling professionals understand how to quickly diagnose and repair problems, saving you time. Experts also understand how to ensure your system adequately covers the size of your home and bigger isn’t better.
