Looking at lists of features can only do so much when it comes to learning what to expect if you have a ductless system installed in your home. Ideally, you can look at what other people have to say about how ductless HVAC worked for them before making a decision.
Our customers have shared with us some things they learned after purchasing their systems and now, we’d like to share them with you. Keep reading for some of the secrets heat pump owners want you to know and how N.E.T.R., Inc. can help you decide if ductless heating and cooling is right for you.
1. Ductless Systems Have a “Dry” Setting
If you have a ductless system, you may not be aware that it has a “dry” setting. This setting is designed to remove excess moisture from the air and can be particularly useful in humid climates. To use the dry setting, simply set your thermostat to the “dry” position. You may also need to adjust the airflow settings on your unit.
The dry setting can help to reduce the risk of mold and mildew growth in your home. Mold and mildew thrive in moist environments, so by keeping the air inside your home dry, you can help to prevent these potentially harmful organisms from taking hold. Additionally, this setting can help to improve indoor air quality overall by reducing dust and other allergens in the air.
2. Cleaning & Maintenance Is Critical
Ductless HVAC systems require regular cleaning and maintenance to function properly. You really can’t go months or years without proper care, or your system can break down or operate less efficiently. You can help keep your ductless HVAC system clean and well-maintained by:
- Cleaning the filter regularly. Depending on the type of filter your unit has, you may need to clean it every month or two. Check your owner’s manual for specific instructions on how to clean your filter.
- Keeping the area around your units clear of debris and dust. This will help ensure proper airflow and prevent dirt and dust from getting into the unit itself.
- Having a professional service your system. Professional maintenance and inspection can help identify any potential problems so they can be fixed before they become major issues.
3. You Might Not Need Your Backup Heating System
If you have a ductless mini-split system on top of a central HVAC unit or wood stove, you might not need your backup heating system as much as you think. Ductless systems are very efficient and can heat your home even in weather as frigid as -13 degrees Fahrenheit.
That said, there are a few things that can impact whether or not you need your backup heating system. First, if your ductless system is too small, it won’t be able to heat your home adequately in cold weather. Also, if you don’t have a backup generator, your heating system isn’t going to work. You can install a battery or other backup power source to make sure that your ductless system continues to operate even if the power goes out.
In most cases, it’s still a good idea to keep your backup system installed even if you don’t use it very often. With climate change and severe weather becoming more unpredictable, it’s arguably best to have both just in case.
4. All Cassettes Need To Be On the Same Mode
If you have more than one cassette in your ductless system, they should all be on the same mode. If one indoor unit is set to “cool” mode while the others are set to “heat” mode, for example, the system will not work as intended.
While the cassettes can operate at different temperatures, you will need to select the same core setting for each. If you would like to have a ductless system that can cool and heat simultaneously, talk to an HVAC professional about installing two or more outdoor condensers.
5. You Need To Protect Your Units From Damage
One of the most important things you can do as a ductless HVAC owner is to protect your units from damage. Cover indoor units when painting or doing home renovations, and outdoor units during severe weather events. Pull leaves and debris off units after a storm, and regularly check your units for any signs of wear and tear. Ignoring small problems can often lead to bigger ones down the road.
