An HVAC system is a large investment on your part. We're not just speaking in reference to the initial costs of purchasing and installing the equipment, but we're also referencing the amount of money you will spend on energy bills over the years. Statistics say that you will spend well over $2,000 this year on energy bills alone. Your HVAC system accounts for almost half of the energy your home consumes within that time period. Your home, no matter how old or new, is an energy hog. Whether you're choosing to upgrade your existing HVAC system or installing a new one in your new home, here are some tips you should adhere to in order to choose the proper-sized system that will ensure energy-efficiency.So what does one do to prevent your home from sucking up so much energy? First, understand that if your equipment is old, it's time to replace it. Equipment that is 10 years or older is extremely inefficient and should be replaced, preferably with an energy-efficient model (i.e. Energy Star qualified). When purchasing any type of HVAC equipment, it's smart to go with an energy-efficient model. It will save you a ton of money over the years. You're probably wondering, "So if I choose energy-efficient equipment, why does sizing matter?" It matters! Choosing the proper-sized equipment (i.e. proper heating/cooling output) directly affects your comfort, your HVAC system's efficiency and its maintenance and operating costs. You can see how important and underestimated this topic is. In fact, it has been estimated that over half of the HVAC industry does not size your HVAC systems properly."Oversizing" tends to be the biggest mistake that is made. When you oversize an HVAC system, it can affect a number of areas within the process. For example, the installation will be more expensive. Typically oversized systems tend to cost more to operate, break down often, run inefficiently and require more maintenance. Oversized air conditioners tend to shut off before they've had a chance to dehumidify the air properly. This results in a clammy environment that may be prone to mold. Oversized furnaces create uncomfortable temperature swings.When your HVAC technician attempts to size your system, they should not be reading a label or simple by-the-book standards. Instead, the calculation should be multi-variable and include factors that are unique to your situation. For example, what is the climate like in your area? How many windows do you have and what size are they? How much insulation is there and what type of insulation is it? How big is the house? Is the house two-story or one-story? How much outside are is sneaking in? How many occupants are there? There are two industry standards that should be used to help determine the proper size for your system. These are "Manual J" and "Manual D", created by the Air Conditioning Contractors of America. Manual J, also called "Residential Load Calculation", is primarily used to determine HVAC size calculations. A reputable HVAC company will tell you that they use Manual J to determine sizing. Manual D, also called "Residential Duct Design", is used to determine duct sizing. When looking for a company to help install your new HVAC system, always be sure to inquire whether or not they use Manual J and D in their sizing and installation process.
Gas Furnaces Repair - Common Problems and Their Solutions
The furnace is hot and every once in a while the burner will come on for a short time and then go off again. But the blower that should be running to circulate the hot air from the furnace to the house is not working. How can you fix that? It really isn't very hard.It does not matter what the fuel of your hot air furnace is. If the blower is not circulating the air through the heater then you are not getting warm. The function of the blower is to move the heat from the heater to the space that need to be heated.A few simple tests can tell you what your problem is. Do you have power going to the motor that runs the blower? If you have power going to the motor and it is very hot than maybe the blower wheel has come lose and it is stuck on something that is keeping it from turning. Try to turn the wheel to see if it is stuck. If the wheel is not hitting anything and just turns hard then the bearings of the motor are bad and the motor needs to be replaced. In some rare cases the motor has little tubes to the bearings and some oil can be worked into the bearings to free them up. This is a long a tedious process, but I have done it successfully a few times. If the wheel is hitting something, then try to see if it can be fixed. Sometimes the set screw will just come lose from the shaft and repositioning the wheel and tightening the screw will fix the problem.Sometimes power will be going to the motor and nothing at all is happening. Replacing the motor is then the only option. The worst case that happens and is one of the most common problems is for the hub of the blower wheel to brake off. This lets the inside of the wheel fall down on the motor shaft. The metal from the wheel will saw off the shaft of the motor rather quickly as it is spinning trying to run the blower. The result of this is a ruined wheel and motor. This gives a brief overview of some of the many things that may happen to your blower in your hot air furnace. I have encountered many other things over the years, but these are the most common problems. It will give you a few things to look for if you are having problems. Be very careful because many times the edges of the metal pieces are very sharp. You can be cut very easily when checking or handling these parts. I know and have the scars to prove it! Do not be in a hurry and be safe.
