Everyone receives advice on their air conditioning system. Unfortunately, not all of it is good advice. In fact, some of it just flat out doesn't make any sense at all, but if you aren't an expert, you may not know any better. Here is a breakdown on some of the advice that you may have received in the past about your A/C.
1. Temperature Setting
Bad Advice: Maintain the same temperature setting whether you are at home or away from home so that you aren't constantly messing with your thermostat. This will ensure that your home will be at a comfortable temperature when you return home.
Good Advice: While it might sound like a good idea to keep the temperature the same throughout the day to minimize the overall wear and tear on your air conditioning compressor, the truth of the matter is that the A/C will actually run less often if you increase the temperature setting by about 10 degrees during the time of the day that you won't be at home, such as when you are at work. This will reduce the wear and tear on the system's compressor, save money on your utility bill, and mange the humidity in the home. If you are worried about messing with the thermostat to do this, consider having a programmable thermostat installed, which will ensure that your home will be cooled back down before you get back home.
2. System Size
Bad Advice: Purchase the largest system that you can possibly afford so that your cooling needs will always be covered.
Good Advice: It is important that you only buy a system that is properly sized for the size of your home. This is a task that should be handled by a professional and licensed HVAC professional. If you purchase an oversized system, it will cool down your home, but it will do so too quickly, which will result in the system turning off before it has a chance to dehumidify your home sufficiently. This process is known as short cycling, and it wastes energy, meaning that your utility bill may be higher than necessary.
3. Open/Closed Vents
Bad Advice: Close vents to rooms that are not being used.
Good Advice: When you close a vent to an unoccupied room, the cool air that travels through the duct to that room simply gets trapped in the duct. Therefore, you aren't saving any money by closing the vent. If there are rooms within your home that do not need to be cooled, then the best option is to consider a zoned cooling system. This type of cooling system will divide your home into several zones, with each zone having its own individual thermostat, and the ducts will have dampers installed that will open and close accordingly.
