Ductless Heat Pumps (Mini Splits)
Ductless Heat Pumps are perfect solutions for clients who:
- Currently heat with electric baseboard.
- Wish to supplement existing boiler system.
- Don’t have a central air handling system.
How Ductless Heat Pumps Work:
Refrigerant in the tubes extract heat from the outside air and brings it inside, quietly distributing warm air to the interior space.
In the summer months, the process is reversed, warm air is removed from your home. Which means you get a fully functional air conditioning (AC) unit at no additional cost!
Ductless – These units have no ducts. So they avoid the energy losses associated with the duct work of central forced air systems.
Excellent Add-On Option – For homes with “non-ducted” heating systems. Such as hot water heat (hydronic), radiant panels, and space heaters.
Efficiency – A heat pump moves heat instead of generating heat, which means more energy efficiency. The system works best as it stays constant, as you can keep the system running continuously without worrying about sky-high energy bills.
With newer technologies exclusive to E.T. Mechanical, and expert installation by our extensively trained service team, our ductless heat pumps saved our clients up to 60% on their heating costs last winter.
E.T. Mechanical Ltd. provides Ductless Heat Pump sales, installation, and maintenance service to Fredericton, New Brunswick and surrounding areas.
Heat Pumps – Frequently Asked Questions
What temperature is a heat pump not effective?
Do you really save money with a heat pump?
With the added benefit of being able to cool your home in the summer months. Heat Pumps not only helps you save, but contribute to year round comfort.
How does my heat pump work with my other heat source?
During cold winter months (February & January) a power bill should be expected to rise as the system has less ideal temperature to run. The entire season’s results will show savings. Relative to outdoor temperature and where the heat from a system will travel, it may also be necessary to run heat sources (ex. Electric baseboard) in other parts of the home. Don’t worry, as these sources will only be supplementing at a fraction of their regular use. To some measure, heat from the ductless system will reach these areas, and less heat is produced by the alternative (such as electric baseboard) in order to reach a comfortable temperature.
We recommend all systems be shut off at -15°C (with the exception of our cold climate heat pumps), this will assist the lifespan of the unit as it works hardest during colder temperatures. This will also maintain efficiency of the unit, as at this temperature the cost of operation is the same as electric baseboards.
Why is my heat pump making a temporary rushing water/ crackling sound/ vibrating noise?
It is cold outside; why is my heat pump not working?
It may also make an unusual sound when this mode is activated. In this mode your heat pump may not appear to be pumping out hot air. If this is the case, it is best to leave the unit alone until it has gone through this cycle. If you know it is going to be cold and frosty overnight, you can be sure your system will go through at least one of these cycles. The colder the temperatures that a heat pump operates at, the more often defrost cycles must occur. The unit is removing frost and ice buildup, in order to run as efficiently as possible.
Should I turn my Heat Pump off at night?
Heat pumps are most efficient when they slowly maintain the temperature of the room. When a large difference in temperature is required (more than 1°C), compressors ramp up, and a heat pump will activate alternate/backup modes of heating in order to quickly achieve temperature.
It is possible to turn a heat pump down overnight. Program the system to drop 1°C every hour, and rise 1°C every hour to when you wake up.
Generally it is recommended to have the home stay a consistent temperature.
How often do I need to clean my heat pump?
E.T. Mechanical recommends becoming a club member to guarantee an annual visit by our technicians. This will help your unit to continue to run as specified and to its full capabilities.
For more information on how to best keep your filters clean see our user guide.
How high can I increase the temperature on my Heat Pump?
Why does my heat pump blow cold air when it starts/or runs?
Heat Pumps are designed to gradually rise to a desired temperature over a long period of Time with a small heat output and a large amount of air flow. A comfortable temperature could be considered 22°C, yet our body temperature is 37°C; because the Heat Pump is producing air potentially colder than our body temperature the outputted air could seem lukewarm or even slightly cold to the touch. Don’t worry; this is part of its normal operation of being efficient and producing proper comfort.
What is that smell coming from my new heat pump?
After cooling season aux heating elements that have been unused for an entire season have been coated with dust, once auxiliary heat is initiated this dust burns off and has a temporary but distinct odor.
Do I need to clear the snow from around my heat pump?
Why is my indoor fan running but my heat pump is off?
This energy saving feature is enabled when the fan is set to “Auto” mode. In addition, the fan can be set to run continuously in the “On” mode creating perpetual airflow through the ductwork, and to better mix air in the home providing more consistent temperatures.
Why is my Heat Pump steaming large plumes?
Why is my Heat Pump Leaking?
Possible issues that can cause your heat pump to leak:
– Drain is Clogged: The drain is used for condensation, sending extra moisture outside of the home. If the drain pan becomes clogged with algae, random debris, or other obstructions it causes the drain pan to overflow, creating a puddle of water by your heat pump.
– Refrigerant Level is Low: Lack of refrigerant can affect the evaporator coil’s ability to absorb heat. So as condensation forms along the indoor evaporator coils it can freeze into ice. Ice prevents the transfer of heat and hinders your heat pump’s functionality. As the unit turns off, the ice will melt and create the water that you have identified as a leak.
If ice form on the outdoor condensing unit the defrost function will activate, transferring heat outdoors to melt the ice. The water will slowly drip downwards until it freezes again.
These are a few common issues that can cause your heat pump to leak. But until you call in a trained HVAC technician, it’s all just speculation! To diagnose and repair the issue at hand, contact E.T. Mechanical Ltd. to schedule service in your Fredericton, NB area home today.
