Question: I have been told my house has a 2 ton air conditioner. Does this mean my air conditioner weighs 4,000 lbs? Answer: The first air conditioning or cooling was done in theaters by hanging tons of ice in nets and circulating theater air across the ice to cool the air. In turn the ice would melt. They calculated that one ton of ice would remove 288,000 BTUs in a 24 hour period or 12,000 BTUs per hour. Your 2 ton air conditioner may only weigh 170 lbs but it removes 24,000 BTUs per hour of heat from your house. Tonnage refers to a rate of cooling.
Question: I change my furnace air filter in the winter and the summer because I have air conditioning. Is there a filter on my air conditioner outside that needs cleaned or replaced? Answer: There is no filter to change out by your air conditioner, but your condenser coil does need washed or back flushed with a hose. The condenser coil, which is similar to a car radiator, can get blocked with grass clippings or cottonwood from the trees. This is very detrimental to your air conditioner. We recommend a precision tune up and professional cleaning in the spring before you use the system for the hot summer months.
When it comes to maintaining your home, people often forget about two unseen and often unheard appliances; your furnace and air conditioner. Besides it being important to maintain those pieces of equipment at least once a year, it is extremely important to change your filter at least once a month (depending on the type of filter or type of air cleaning equipment that is attached to your HVAC system). Most filter systems are located to the right or left of the furnace, attached to the return air trunk. The air in the return air trunk is pulled from various areas of the home down through the large trunk and passes through the filter just before entering back into the furnace. It is very important to know the type of filter you have in place in order to know how often it should be changed. On average, if you have a 1 thick filter, it should be changed once a month. It could need changed more if you have pets, or if there is something that creates more dust or dirt in the air. Keeping a
