If you want a single system that provides both heating and cooling, a heat pump may be the solution. We can configure the equipment to work with or without ductwork. A ductless setup is an excellent option for homes with energy-efficiency goals. If you’re wondering whether your house in St. Louis, MO, is a good fit, we can help you evaluate your options.
Your Home Doesn’t Have Ductwork
A heat pump doesn’t need air ducts because it pushes the warm or cool air into your living spaces through one or more air handlers. This simplifies the installation process and causes less disruption to your home. If you’ve recently built onto your house, you can easily heat and cool the new space with ductless equipment.
Certain Parts of the House Stay Warmer or Cooler Than Others
If you have central heating or cooling, it’s not uncommon for certain rooms to stay warmer or cooler than others. This often happens when there are blockages and leaks in the ductwork. It can also be the result of poor airflow design or improper system sizing. With a heat pump mini-split, you have precise control over the temperature in each space with an air handler. This makes it much easier to avoid hot and cold spots throughout the home. You’ll enjoy even heating and cooling year-round.
You Want to Use the Garage as Living Space
A lot of people like converting their garages into bedrooms, home gyms, or office space. Yet, these areas don’t usually come with heating and cooling because they aren’t connected to the HVAC system. By installing a ductless mini-split, it becomes possible to add climate control to the garage without overloading the main system. You’ll be able to heat and cool the space throughout all the changing seasonal weather.
Indoor Humidity Feels Hard to Manage
St. Louis experiences fluctuating humidity levels. In the summer, humidity stays high, which can make your indoor spaces feel warmer than they really are. During the winter, the dry air causes the living spaces to feel cooler, increasing your furnace operation. If you want better control over indoor humidity levels, a ductless system may be a good fit. Heat pumps run at lower speeds, allowing them to balance humidity more effectively. You also won’t have to worry about moisture intrusion through leaky ducts when there isn’t any ductwork.
Balanced moisture throughout your home is beneficial for multiple reasons:
- Lower chance of mold growth
- Improved indoor air quality
- More consistent indoor comfort
- Less strain on HVAC equipment
- Better protection for furnishings
Your Existing Ductwork Is Leaky and Damaged
If your home has damaged or leaky ductwork, this issue prevents the conditioned air from reaching the intended rooms. The HVAC will work harder to keep the home comfortable, which means higher energy costs. It also means more wear and tear on the equipment and more frequent repairs. If you opt for a ductless system, you won’t need to have the ductwork repaired. Instead, we’ll install one or more air handlers to match your comfort needs. The outcome is a system that keeps the home more comfortable without the risk of duct leaks.
You Prefer Room-By-Room Temperature Control
When multiple people live in the home, room-by-room temperature control becomes extremely valuable. With a central system, it can sometimes be difficult to maintain a consistent temperature throughout each room. Ductless takes comfort to the next level with its zoning capabilities. Many houses have a setup with air handlers in the main living areas and each bedroom.
Your Bedrooms Never Feel Comfortable
Bedrooms are particularly vulnerable to uneven temperatures, especially those on the upper level of a home. These rooms tend to feel much warmer than the rest of the house because heat rises. This means the lower-level rooms usually feel cooler, especially during winter. Ductless setups solve this problem. You can place an air handler in each bedroom to maintain consistent comfort. To keep your sleeping space at a lower temperature than the rest of the home, this configuration makes it easy.
Reducing Your Home’s Carbon Footprint Matters
How you heat and cool your home plays a large role in its overall carbon footprint. Homes with large footprints are those that use excessive energy and rely on inefficient systems. They impact the environment negatively by producing higher carbon emissions. With a ductless heat pump, you get one of the most efficient forms of indoor climate control. The system won’t use as much energy because it transfers heat rather than producing it to both heat and cool.
You’re Ready to Replace Window Units and Space Heaters
There are a lot of older homes in St. Louis that still rely on window air conditioners and space heaters. Although these options work great as temporary solutions for keeping a home comfortable, they can be costly and noisy to run. Space heaters also present a fire risk. Upgrading your home to a ductless heat pump offers a simple way to maintain consistent comfort year-round. You won’t have to move portable units from room to room or fret about safety concerns.
Your Older Home Has Limited Ductwork Access
There are also a lot of older homes in St. Louis, especially downtown, that weren’t originally designed to work with today’s modern HVAC systems. They often feature plaster walls, tight chases, and other architectural features that make it difficult to install or access ductwork. When you opt for ductless, you don’t have to stress about these limitations. We’ll install the mini-split carefully while preserving the home’s unique character.
Indoor Air Quality Needs Improvement
Ductwork tends to get dirty over time, especially if you don’t have it regularly cleaned. And as the conditioned air flows through the ducts, it mixes with the dirt and dust buildup inside the system. Once the air enters your living spaces and you breathe it in, it can harm your health. The dirty air also causes the HVAC work harder and use more energy. A ductless system eliminates the risk of duct contamination because there is no ductwork.
Heating and Cooling Costs Are Too High
If you use the HVAC like you usually do, but your bills keep going up, it may be time for a more efficient system. You’ll have a unit that uses less energy and the advantage of room-by-room temperature control. If certain parts of the home are unused, you won’t have to heat or cool them. This provides additional savings on your heating and cooling costs.
