Q: What is a heat pump and how does it work?
A:Technically, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space. Installation for this type of system typically consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner. A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units. Think of a heat pump as a heat transporter constantly moving warm air from one place to another, to where it’s needed or not needed, depending on the season. Even in air that's seems too cold, heat energy is present. When it's cold outside a heat pump extracts this outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing heat from your home. One advantage of a heat pump is that it moves heat instead of generating heat, giving you more energy efficiency. Note that heat pumps are best for moderate climates, just like we have here in North Carolina!
Q: How often should I change my furnace filters?
A:It depends. The main rule of thumb is, if it looks dirty, change it! You shouldn’t wait until the filter is completely filthy, because that means your heating and cooling system is not running at its most efficient. For most families, changing filters every three months is a good frequency, but consider changing it more often if you have smokers in your home, suffer from allergies, or have pets that shed fur.
Q: What level of humidity is acceptable in a crawl space?
A:Once humidity levels reach above 70% in your crawl space we start to worry about how the increased moisture is going to affect the house and your health. Once your crawl space gets humid, the possibility of mold, mildew, insects and allergies rises. The condensation in your crawl space can also affect your flooring and joists, adversely affecting the structural integrity of your home. Call us, we will inspect your crawl space and offer you some options to keep it dry and healthy.
Q: My AC isn’t blowing cold anymore. Will adding more refrigerant help?
A:In the short term, perhaps, but there is a reason why your system isn’t blowing cold air. We need to get in there and determine if you have a refrigerant leak or if something more serious is going on. In old systems, refrigerant leaks are common and adding it may buy you some time, but in that case we would want to help you compare the costs between limping along on an old system and replacing it with a new, high efficiency option.
Q: I am getting a new unit. How big should it be?
A:Helping you figure this out is one of the most important services we offer. A system that is too large will cool or heat your house quickly, but you may not feel comfortable because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air. On the other hand, a system that is too small can’t get the job done, especially in extreme weather conditions. The air conditioner will run constantly in the summer and the furnace will do the same in the winter. Your friends at Comfort South will visit, assess the type of house, examine walls, windows, insulation, basement and attic conditions, house orientation, and so on. We will show you exactly what you need to be comfortable.
Central heating is a heating system that integrates air circulation through a blower or a fan. Forced-air systems are very common in American homes.
