How Does Weather Effect My HVAC System?
It goes without saying that the more extreme the weather conditions are, the more stress it can put on your HVAC system. Both extreme cold and extreme heat can cause your system to work overtime to heat and cool your home, but that's not the only way weather affects your HVAC system.
Rain and Wind Storms
As a rule, rainstorms won't make a lot of impact on your HVAC system; however, there are some things you need to consider.
- If flooding occurs as a result of a rainstorm it could pose a risk to your outside AC unit. Typically, the water would need to rise about 15 inches (38.1 cm) to submerge the inside components in your AC unit and pose a serious problem. An inch or two of water won't reach the inside elements and won't cause a problem. Unless you are expecting torrential downpours or your area is prone to flooding, storms should not pose a threat to your HVAC system.
- Strong winds during storms can pose a problem if they blow down tree limbs or blow other yard debris. Flying objects can damage your AC unit. Removing dead tree limbs and putting away lawn furniture and other objects when high winds are expected will help prevent damage to your AC unit.
Can you run the AC in the rain?
Running your AC unit during rainstorms does not pose a danger to the unit. In fact, it might be a good idea. Not only will it keep you cool and comfy inside, but it will also help eliminate moisture in the air. This will head off issues with mold or mildew that can grow in warm, moist areas.
High humidity levels doesn't pose an immediate threat to the health of your HVAC system, but it will put more stress on the system as it works to remove excess moisture from the air. Over time this stress may take its toll on your system. If high humidity is an issue in your location, consider getting a dehumidifier to give your AC a helping hand. Likewise, running a humidifier in the winter will help keep the air in your home more comfortable and it will feel warmer, too.
With regular maintenance, your HVAC system should perform efficiently throughout the year. If your system is not performing as expected, our professionals at Action Heating and Air, Inc. are ready to help you.
