It’s the heat and the humidity that makes all the difference. This is when I found out that humidity and HVAC are closely connected to each other. As the temperature and the humidity increase, you slowly change from the furnace system to the air conditioner system.
This directly proves that humidity is a factor that matters both in winters as well as summers. When it comes to the winter season, moisture can take a big toll on the HVAC equipment and affect the cooling system badly.
What’s High Humidity? Why does it matter?
There is nothing but air saturated with water vapor and high humidity indicates that air can’t hold any more water.
A humidity level below 60% is the normal one, but this doesn’t remain the same throughout the year. (also, different geographical regions have different moisture levels. However, 60% is considered for most of the discussions)
Heating and cooling experts recommend having moisture less than 60% but it is actually not possible to maintain the same moisture level inside the room.
What causes high humidity in the house?
Well, who even likes humidity in the first place? It makes us feel uncomfortable, makes the skin oily and you keep sweating almost all the time. Talking about the high humidity causing factors, there are many of them! They are listed as follows:
If you are someone who can’t live without hot steam showers, then you may have to deal with the humidity inside your washrooms. Washrooms are humid at all times, and now you know the reason. It is basically the process of condensation. To reduce the humidity, you can try taking fewer hot showers and even install a dehumidifier (if you really can’t miss hot showers)
Using Indoor Space For Laundry Drying
We all are well-aware of this point. Yes, if you or your parent use the indoor area for laundry drying then this will automatically raise the humidity level inside your home. (keeping your wet clothes to dry inside the room is just similar to splashing a bucket of water into the air)
So where will the evaporated water from the clothes pass? Air, space – making the room all damp and humid for you. You can use a dehumidifier to control and adjust as per your need.
Air circulation is necessary, and if your home has a bad ventilation property – then it can be a reason for the moisture affects HVAC. A well-ventilated room has an ability to remove bad, stale air out and making space for the fresh air to pass. With no movement of air, the indoor air just remains and stays at the same place which may lead to mold generation (if not attended properly).
Go for an air purifier in this case.
Gas Heater Systems
Gas heaters work with the burning of the gas, and when you burn gas, water vapor is generated. That’s science. Again, the same thing occurs, I know you have guessed that by now. As water vapor is generated, it creates wetness in the air. A dehumidifier can make things better in this case.
Coastal Space Or The Geographical Space
If you are living closer to coastal space or areas with heavy rainfall – you will experience high humidity due to the constant evaporation process. You can make use of dehumidifiers in this case and bring some comfort during high humidity levels.
Renovations are great, once it is over.
Jokes apart, if your home is undergoing some sort of renovations with plaster cement and the painting jobs – this can turn your room into a high humidity one instantly.
In case you feel like the paints and the air is not drying up quickly for you, then you can check out the best dehumidifiers in the market and enjoy it.
Does extreme humidity affect HVAC Performance?
High humidity conditions can affect the HVAC performance badly, and we are specifically talking about the air conditioner units.
To be honest, when the level of humidity increases, the systems won’t have enough energy to deal with it. So, when the humidity rises your room will feel warmer than it is.
Following are the different ways in which humidity could affect the heating and cooling system efficiency.
- If you are using an oversized HVAC system, it won’t efficiently remove the humidity. The constant turn-on or off of the power compressors, the unit never runs enough to remove the humidity. You can install a small-sized AC unit to solve this issue.
- The same scenario is seen for the single speed air conditioning unit. Even the single-speed ac units will have a similar condition as seen in the oversized ones. Here the air conditioner will run in its full energy, and once it reaches the set temperature and turns off until the thermostat threshold value.
- Thirdly, your home may get negative air pressure if too much of the air passes out of the ducts. This is the case of a bad ventilation system, and when more negative air pressure is found inside the rooms – the air tries to balance the negative air condition by taking in more of the outdoor air. To solve this condition, correct the ventilation condition and you would be good to go.
- If you keep your room fans running all the time, this could be another reason for the increasing humidity. Keeping your fan running along with AC could bring back the humidity removed by the air conditioner.
Now that you know what causes humidity, I am sure you could manage it better!
Measures to Keep your HVAC Systems Safe from Humidity
During the winters, the room humidity is comparatively lower than the required level. In this case, you are required to use a humidifier and set it up at the required level to bring the missing comfort.
This is something different than the summer months – where you use a dehumidifier for reducing the humidity of the rooms.
During the winter months, you are recommended to have 30-40% of moisture, it may be higher or lower as per your preference. Enjoy the warmth and preserve your HVAC systems for a longer time.
