How to choose between an air conditioner and a heat pump?
As the purchase of an air conditioner for your home is an important choice, it is essential to be well informed before making your decision. An air conditioner will only allow you to cool your home in summer, while a heat pump will also allow you to heat in winter by reversing its operating cycle. The heat pump will save you on your electricity bill since it is much less energy-consuming than your main heating system (furnace, electric heaters, etc.).
What is the average lifespan of my system?
A heat pump or central air conditioner or bibloc without ducts will have an average lifespan of 10 to 15 years. An electric or gas furnace will have an average lifespan of 15 to 20 years.
What are the advantages of having a forced air system?
Thanks to ventilation ducts, these systems provide more uniform heating in all rooms of the house. Air is distributed through the ventilation ducts and the temperature requested on the thermostat is quickly reached in all rooms of the house, even if the doors of the different rooms are closed. In addition, with a central forced air system, it is possible to add accessories to improve the comfort of the residence. You can control the humidity level of the residence by adding a central humidifier. You can also air condition the house by adding an air conditioner or a heat pump. It is also possible to add an ultraviolet lamp to help neutralize the presence of bad odor and purify the air by eliminating bacteria, mold and allergens.
Why does smoke come out of my heat pump in winter?
When the temperature approaches freezing point or drops below 0 degrees Celsius and the outside humidity is high enough, it is normal to see water vapor escaping from the heat pump and to notice a thin layer of ice or frost on the outside coil of your heat pump when it is in heating mode. This phenomenon constitutes the defrost cycle of your heat pump and is essential for its proper functioning. In fact, thanks to the defrosting mode, the ice contained on the outside coil melts, which causes the escape of water vapor, which is similar to a slight white smoke. During the defrost cycle, the outdoor fan stops working, then the heat pump starts air conditioning for a few minutes, so the compressor can make a little more noise during this step. Finally, the heat pump returns to heating mode. The defrosting cycle can be performed every 30, 60 or 90 minutes depending on the case. So, it is important to remember that a thin layer of ice or frost on your heat pump and that the exhaust of water vapor is completely normal during the cold period.
Do I have to set my thermostat in ON ventilation mode or in AUTO ventilation mode?
Ventilation occurs through the blower system located inside the house. In fact, it is important to understand the difference between these two modes. Automatic mode means that the fan will only operate when your thermostat indicates a demand for either heating or cooling. When the demand is reached, the fan stops working. The ON mode means that the fan operates constantly, 24 hours a day, 7 days a week. Thus, there is always air circulating in the house even if there is no demand for air conditioning or heating. Obviously, running the ventilation in ON mode costs the user a little more in electricity costs since the system is constantly running. However, this mode prevents premature wear of the ventilation motor. Indeed, closing and reopening the motor on each request in AUTO mode causes much more damage than constant use. Use in ON mode will require a more frequent filter replacement since the air will circulate there continuously. Finally, using ON mode will allow better distribution of heat or air conditioning in all your rooms. Indeed, some rooms can be exposed to the sun all day, and others remain in the shade. This will increase the temperature by several degrees in certain rooms of your house. Operating the ventilation 24 hours a day, 7 days a week will redistribute this heat from the sun to even out the temperature throughout the house.
What is TRES or SEER?
SEER means "Seasonal Energy Efficiency ratio"
TRES in French means "seasonal energy efficiency rate"
This rate is used to calculate the efficiency of the device in air conditioning. The higher the rate, the less energy the device consumes during operation.
What is a ton?
One ton measures the capacity of the unit in air conditioning. One ton is equivalent to 12,000 BTU / h. Several factors can influence the choice of the right tonnage such as: the surface to be heated or air-conditioned, the static pressures in your central system, the exposure to the sun, the location of the bibloc wall-mounted appliance without ducts and the layout of the rooms of your residence.
What is HSPF?
HSPF means "seasonal heating performance factor". Thus, the HSPF measures the efficiency of the heat pump in heating. The higher the rate, the less energy it consumes during operation.
What is BTU?
BTUs are used in industry to indicate the amount of heat that can be released by a device. Several factors can influence the choice of the right number of BTUs such as: the area to heat or cool, the static pressures in your central system, the exposure to the sun, the location of the ductless bibloc wall unit and the layout rooms in your residence.
How often should I replace my air filter?
The lifespan of a 4 "thick filter is approximately 3 to 4 months or more depending on the concentration of dust in your home. However, a 1 "thick filter should be replaced every month, and the 2" filters every 2 months. We offer a filter delivery service, fees vary depending on your residential area.
