Today’s article deals with the practical, day to day, homeowner questions. The answers are kept simple so that the consumer can readily use the information without becoming an expert.
Q1. How are the sizing capacities of heating and air conditioning systems measured?
Heating and cooling equipment is sized on the B.T.U.H (British Thermal Units per Hour). Air Conditioning and Heat Pumps are also rated in tonnage – 12,000 BTU/HR equals one ton of capacity. Residential systems can range from 1 to 5 tons.
Q2. Is it important to get the right size heating and cooling system?
Yes! It is very important to have a professional “size” the needs of your home when installing either new or replacement HVAC equipment. Heating or cooling systems that are OVERSIZED will not run as frequently or as long as they should resulting in poor humidity control. These miss-sized systems will cycle too often and often lead to temperature variations. Over-capacity systems will also be less efficient costing the homeowner to spend more energy dollars per year. Under-capacity systems simply will not properly heat or cool the residence causing a very uncomfortable place to live.
Q3. What air temperature should my air conditioner produce?
The air temperature produced by the system depends on the temperature of the air going into it. At ServiceMark Heating, Cooling and Plumbing we look for a 15 to 20 degree temperature below the incoming temperature. So if the home is presently at 80 degrees, the outgoing supply register air should register between 60 and 65 degrees. Remember, it takes time to remove the humidity and lower the room air temperature if the homeowner has let temperatures get too high before starting the air conditioner.
