Over the years there has been a lot of technological advancement in the HVAC industry.
There are better, more efficient units in the markets today.
While there are vented units that provide warmth and cooling, there are also vent-free systems. There are some units that are more popular than others. When a HVAC system is popular, knowledge lags. There are more myths than facts during this period and it is no different for the ductless heat pump. I am a victim of one of these myths. I thought the noise was a normal occurrence for this unit. I later found out from a heating technician, that even though this unit has outdoor central heating and an indoor electric furnace, it is as quiet as a fridge. It turns out that the furnace was leaking and hence the whining noise. If I had not contacted the engineers, I would have a disaster on my hands as at the same time I had my gas fireplace. Another myth is that this unit cannot handle cold weather. When the heat pump install is done properly, this unit is supposed to provide quality heating throughout the cold season. It is a fact that these units can run longer than a traditional dual fuel system, however, some energy saving tips learned from my local contractor is to always set the temperatures low when sleeping or when not in the house. Another myth is that these vent-free units are huge because they have indoor and outdoor parts but they are relatively smaller than traditional ones. These units provide both cooling and heating services just like the zone control unit. Similar to a fireplace, these units do not need too frequent maintenance, once a year is sufficient.
