What Causes Mold Problems in HVAC Systems?Mold spores are prevalent in the air. If you were able to shrink down to the microscopic level, you’d see the atmosphere filled with spores of all kinds. To the naked eye, spores are invisible. If they happen to land on a nice moist spot in your home, then the real growth starts. Mold can be dangerous, so you need to take its growth seriously. Some molds can cause nasty health side effects. Other molds may not be noticeable. People who are sensitive to molds, have asthma or other respiratory issues are the most likely to experience adverse health effects. If you or someone in your home fits this description, it’s imperative to keep a watchful eye on your HVAC system for any signs of mold growth. When it comes to air conditioners, mold tends to be a fairly common problem. Dealing with and preventing mold is a part of proper air quality control. Understanding what causes mold growth and how to handle it when it pops up is essential to keeping your home’s air clean. You should be aware of a few problem areas when mold issues start to bother your HVAC system.
HumidityMold needs moisture. If you can control moisture in your home, you’ve got a good shot at keeping mold at bay. Handling humidity is easier said than done, especially if you live in a particularly humid environment. When the summer months come, and the rain starts to fall, dealing with the mugginess from the outside is almost impossible. Humidity is going to get into your home. If you don’t do anything about it, humidity can be the catalyst for mold growth inside your home and HVAC system. Indoor showers, baths and saunas are common producers of humidity, so keep that in mind.
CondensationThermodynamics is tricky, but condensation is common. While some of us might not understand how it happens, we can all be victims of the results of condensation in your ducts and your main unit. The cooling process that your HVAC system goes through each day produces condensation. Normally, this excess moisture is moved away from the system through the condensate pan. However, clogs or other issues can prevent proper draining. Clogged condensate lines create standing water. Standing water creates mold.
Poor VentilationIf moisture is the issue, then proper ventilation is the solution. Ensuring that your home is adequately ventilated and that moisture has somewhere to move is integral to battling mold. Without ventilation, stagnant air pockets can form in your home. Moisture that has nowhere to go is the perfect scenario for mold growth. Bathroom fans and range hood exhaust systems are some common problem areas where ventilation is an issue.
Signs of Mold in HVAC SystemsSince mold spores are virtually invisible to the naked eye, how can you spot mold growth in your HVAC system? Severe mold infestations are usually easy to spot. In cases where mold has been left unattended, you can spot speckles on air registers and vents. Another tell-tale sign that mold is living rent-free in your home is the odor. If you are experiencing a particularly funky smell, it could mean you’ve got some new moldy neighbors — think wet dog with a touch of old cheese. HVAC specialists are no strangers to mold, and they will know what’s what when it comes to your system’s mold issues. So if you are on the lookout for mold, Sterling HVAC specialists Cardinal Plumbing, Cooling and Heating are here to help.
How to Prevent Mold ProblemsIf you are sufficiently afraid of mold at this point, you may be wondering: “how can I prevent mold?” Good question. Humans have been dealing with mold as long as we’ve been living indoors — even further back if you count cheesemaking and other moldy endeavors. The one thing we have gleaned from years of battling stubborn molds is that if you control moisture, you control mold. Therefore, moisture control should be your strategy to prevent nasty mold infestations. Here are some tips to help you prevent mold growth in your HVAC system:
- Replace your HVAC filters regularly
- Insulate air ducts to help reduce condensation
- Check and clean your condensate/drip pans
- If you find leaks, handle them promptly to prevent moisture build-up
Steps to Remove Mold from Heating and AC SystemIf you are looking at the moldy spots near your vents with frustration, here is how you can channel that rage toward tackling that nasty infestation. First, remember that mold can be dangerous. You need to don the proper PPE when handling mold problems. This means:
- An N95 mask
- Industrial grade gloves
- Safety goggles
- One tablespoon household detergent (dish soap or detergent)
- Half tablespoon baking soda
- One cup water
- Turn off your HVAC system and make sure all the heating/cooling vents are not pushing air.
- Start by spraying moldy areas with cleaner and scrubbing gently with a brush or rag.
- Repeat until you’ve reached all the spots where visible mold is present.
- Dispose of all rags and PPE in trash bags and immediately take them outside.
