Q: What type of thermostat should I use?
A: This is a matter of preference and practicality. Whether you chose to use a manual or electronic thermostat, either one will work just fine. However, an electronic thermostat has been proven to be more efficient.
Q: Should a thermostat be set to ‘auto’ or ‘on’?
A: It should preferably be set to ‘auto’ so that the fan operates only when the temperature changes. This is the most efficient setting.
Q: How do I correctly size a unit for my home or office?
A: It would be best to call Cobra HVAC. This is a complicated process since there are numerous factors to consider such as the living area, climate, number & type of windows installed, insulation, number of people utilizing the space, usage of the space, a type of equipment or machinery in the space.
Q: Should outdoor units be covered in the winter?
A: It all depends on the type of unit and whether or not you have a heat pump which is used year-round. Normally, the majority of the equipment made is designed to withstand the elements.
Q: Is it o.k. to plant shrubs near an outdoor unit?
A: Yes, however, we recommend that shrubs and other plantings be at least 18-24 inches away from the unit. This allows for adequate air circulation in and out of the unit to prevent possible overheating and costly maintenance.
Q: What is a ductless split system?
A: A ductless split system to some degree is a blend between a central air system and a window mount unit. It can be installed in an area which does not have ductwork and in which installing ductwork would be impractical. The advantage is that the unit is much quieter, more efficient, and has more capacity.
