One of the largest problems with home comfort systems is the duct system is not properly designed for the equipment used to heat and cool the home. Your heating and cooling system is attached to a delivery system called a duct system or duct work and it is designed to deliver the air to all of the rooms in your home. In fact all of the air in your home is moved through your duct system 3-5 times per hour. The air is moved by a blower motor that should be correctly sized for your home.
If your duct system is too small it adds resistance to the systems blower motor which makes it harde
r to deliver the air into your home. This causes such things as increased energy usage, hot and cold spots in the home and increased system failure. Imagine a runner going up a hill breathing through a straw. How far do you think he would get before he fell out? Or, imagine a truck trying to drive up a steep hill carrying a huge haul of watermelons. What if the truck did not have the proper gears to reach the top, nor the proper equipment to secure the load of watermelons? This endeavor will take its toll on both the mechanics of the truck, as well on the size of the remaining load of watermelons. Well, having a duct system that is too small is the same thing. Your heating and cooling systems will age faster and deliver inconsistent loads of hot or cold air.
On the other hand, if your duct system is too large for the heating and cooling system it takes longer to deliver the air in the home which creates weak air flow and also increases your utility bill and increased service problems. As your energy bills skyrocket, you are unable to maintain your home at your desired temperature.
70% of the duct systems are designed too small for the equipment they are connected to because it's a way to cut cost during a home's construction.
At 72 Degrees Heating & Air Conditioning, we utilize special diagnostic techniques to determine if your duct system is 
designed correctly and if it is causing things like poor air flow in certain areas in the home, increased service problems and premature system replacements. Experience has proven to us that when your ducts are correctly sized to fit your system, rather than too large or too small, it is easier to control the temperature of your home while still lowering your utility bills. Just picture the same watermelon truck. This time it is making its way up a much smaller hill, one properly suited for its mechanical abilities. Not only are the watermelons not as likely to fall out, but they are also properly secured. The result is less strain on the vehicle and more watermelons for the mile.
