Over the years there has been a lot of technological advancement in the HVAC industry. There are better, more efficient units in the markets this week! While there are vented units that give 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, proficiency lags. There are more myths than facts during this stage and it is no unusual for the ductless heat pump, however i am a victim of 1 of these myths. I thought the noise was a normal occurrence for this unit. I later found out from a heating company, that even though this equipment 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 equipment cannot handle cold weather. When the heat pump install is done properly, this equipment is supposed to give quality heating throughout the cold season. It is a fact that these units can run longer than a traditional dual fuel system, but, some energy saving tips l acquired from my local company is to always set the temperatures low when sleeping or when not in the house. Another myth is that these vent-free units are immense because they have indoor and outdoor parts however they are relatively smaller than traditional 1s. These units give both cooling and heating services just love the zone control unit, however similar to a fireplace, these units do not need too frequent service, once a year is adequate.
