Before Calling an Expert: 5 DIY HVAC Troubleshooting Tips for Homeowners

Is your HVAC system on the fritz? It is true that our heating and air conditioning units can often break down or they may start acting strangely. Things like noise, odors and other issues may occur. But instead of jumping the gun and calling an HVAC repair specialist, you may be able to fix the issue yourself. In most cases, it may turn out to be a small issue and hiring a specialist may be overkill. Usually, the issue has to do with simple maintenance. In the long run, maintenance is the key to making sure your HVAC system stays in optimal working condition. Here are five DIY HVAC troubleshooting tips for homeowners.

  1. Check the filter. In a lot of cases, the issue lies with the filter. Most HVAC systems have a filter that blocks out dirt and detritus. Because these systems utilize the available air, these filters are critical. Eventually, though, the filter starts to become clogged and the entire system can start to malfunction. So, before you hire a professional HVAC technician – take a peek at the filter. If the filter needs to be swapped out, you can easily complete the job yourself.
  2. Check the compressor unit. The compressor unit on your HVAC system is usually located outside – next to your house. The compressor unit contains a fan that sucks in the air and compresses it – that compressed air is then cooled or heats through the process and gets sent into your home to regulate the temperatures. However, if the fan unit has an obstruction, like leaves or twigs, it may cease to work. So, you want to turn off your unit completely and pull out any obstructions.
  3. Check the vent gates. Another issue – which is actually more common than you would think – has to do with closed vent gates. Many people wonder why certain rooms in their home are not affected by the warm or cool air that is emitted from the HVAC system. Well, it may just be that the vent gates are closed. All you have to do is switch them open. These vent gates can be used to control the amount of hot or cool air that enters a certain room, but if they are completely closed, the room may not be affected at all.
  4. Check the refrigerant levels. If your air conditioner has low refrigerant levels, you could be dealing with freezing and even leakage. If you are noticing mold, this could be the issue. So, simply refill the refrigerant and the issue should go away. If you are noticing mold, but the issue has nothing to do with your refrigerant levels, you may want to see what home ventilation can do for you - your issue may have do with not having enough ventilation.
  5. Check the pilot light in your furnace. Another issue you may be having is a blown pilot light. Pilot lights can blow out for a number of reasons, but it is important to keep it lit at all times. So, if your furnace is having issues turning on – try reigniting the pilot light and your system should fire up again.
