Ductless AC vs. Heat Pump – Cooling System Guide
A Guide to Understanding Ductless AC vs. Heat Pumps
Summers in our area can be very humid, but your home can still be comfortable, even if it’s older. Many people are searching for efficient ways to cool rooms that do not have ductwork for central air. At Stan’s HVAC, we are comparing ductless AC and heat pumps to help Ottawa homeowners choose the best option for their comfort and budget.
What Are Ductless Air Conditioning Systems
These systems are split units that do not need the large metal ducts hidden in your walls or attic. An indoor unit is mounted on the wall and connects to an outdoor compressor through a small hole in the wall. They are great for cooling a single room or an older house that uses radiators for heat. Since there are no ducts to leak air, ductless AC systems are often more efficient than window units or older central air systems.
Getting to Know Heat Pump Cooling Systems
A heat pump can cool your living room in July and keep it warm in January without using fossil fuels. It works by moving heat instead of creating it, taking heat out of your home in summer and bringing in heat from outside in winter. Even when it is -25°C in Ottawa, modern heat pumps can still find enough heat to keep you comfortable.
How Ductless AC and Heat Pumps Differ
The two types of indoor wall units look almost the same. The main difference is inside the outdoor condenser and how the refrigerant moves through the system. A standard ductless air conditioner is made only for cooling in summer, while a heat pump has a reversing valve that lets it switch between cooling and heating.
How They Operate
A standard AC unit compresses refrigerant to take heat from inside your home and release it outside, leaving the air cooler. A heat pump works the same way when cooling, but its reversing valve lets it switch to heating in winter. It collects heat from the outdoor air, even when it is cold, and brings it inside to warm your home.
Temperature Control Features
Both systems often include a remote control or can connect to a smart thermostat, allowing you to set different temperatures in each room. This helps you avoid cooling empty rooms and saves money. Heat pumps also let you control heating during mild weather or in the middle of winter, so you can manage your home’s climate all year.
System Design and Components
The equipment for both systems usually looks the same, with an outdoor unit and one or more indoor air handlers connected by refrigerant lines. The main difference is that heat pumps have a reversing valve and often a stronger compressor to handle very cold winters. Some people ask for a ductless AC heater, but what they really need is a heat pump to provide both heating and cooling.
Maintenance Requirements
It is important to keep the filters clean in both systems to maintain good airflow and air quality in your home. Because a heat pump works all year instead of just in the summer, it is used more often than a regular AC. You should schedule professional maintenance more often to make sure the reversing valve and defrost cycles are working properly.
Comparing Cooling Performance
If you only consider how well each system cools your bedroom during a heatwave, both perform about the same. Both use inverter compressors that adjust their speed to keep the temperature steady, instead of turning on and off like older models. Heat pumps may have a slightly higher SEER rating because they are often made to higher efficiency standards.
Energy Efficiency and Cost Effectiveness
Electricity bills can put a dent in your monthly budget. So, efficiency is important for saving money. The cost to run these systems depends on whether you use them only in summer or all year round. Some things to consider include:
- Ductless AC systems allow you to turn off cooling in unused zones.
- Heat pumps offer a high efficiency rate that can be 300% effective compared to electric baseboards.
- Insulation and window quality are massive factors that impact energy consumption.
- Heat pumps often qualify for federal Greener Homes rebates, which offset the higher upfront cost.
Installation and Home Compatibility
Both systems are quick to install and only need a small hole in an outside wall for the conduit. If you have a good gas furnace and only need cooling in summer, a regular AC may be the best choice. But if you heat your home with costly electric baseboards or oil, a heat pump is usually the better option.
