How Cool is your Thermostat?

An important part of every heating and cooling system, the thermostat is how a homeowner regulates the temperature inside their home. Some thermostats have settings to allow week-long programming. Others, they aren’t quite as advanced. Some of the top-of-the-line thermostats can be connected to a smart phone via Wi-Fi and an app. The homeowner can be hundreds of miles away and still control their thermostat.

But what does a thermostat actually do?iS30

When it comes down to it, the thermostat is the temperature regulator for the home. Thermostats are a tool to control the level of comfort/temperature in a particular setting. Some people prefer warmer temperatures, and others prefer cooler ones. With the weather starting to heat up, it is important to make sure your thermostat is in proper working order to keep you comfortable during the warmer months.

If you have a programmable thermostat, make sure it is set for the temperatures you want. And, if you know you will be out of the house for long periods of time (going to work, for example), set it to stay off during those times. This will lower your electricity bill, and who doesn’t want that?

1f971277Some furnaces modulate their airflow. These modulating furnaces have variable speed motors. A variable speed motor is meant to be running 24 hours a day. When it is not heating or cooling it is cycling about 200 cubic feet of air per minute. This keeps the entire house the same temperature. Another added bonus to having the furnace constantly running is the constant filtration of the air.
With a thermostat placed on each level, some units are capable of keeping different levels at different temperatures. The thermostat tells the dampers to shut or open accordingly, and when the temperature called for is met, they close and run on low power mode. An added advantage to the variable speed motors is the conversion of an AC electrical current to DC.  This conversion of energy makes the unit considerably more efficient, and cost-effective.

Thermostats dictate the comfort of the home. Having a functioning thermostat and one that best fits your needs is important to have the highest level of comfort possible. We have a wide range of thermostats to choose from. Come check out our selection at http://www.hvacpartsshop.com/thermostatsandcontrols.aspx! We at HVAC Parts Shop hope to serve you soon!

Shocking Truth Behind Static Electricity

control boardA furnace circuit board uses two types of voltages. First is the control voltage. This always operates at 24 volts. Second is the line voltage. This is used to run the motors, and the voltage required for the line voltage depends on the unit. Typically, this is around 120 volts. With just one touch, a technician or homeowner can burn up the electrical components of a furnace. To avoid this type of incident it is important for anyone working on the furnace to discharge their self of any static electricity before working on the furnace.

Static electricity can build and burn up electrical components without any warning. Typically, when a person feels a static shock, they are feeling at least 3,000 volts of electricity. That is 20-25 times the normal capacity for that board to handle! If static discharges to the board with less than 3,000 volts, but more than the amount needed to run the board, the board can become ruined without any warning.

Grounding the electrical current out of the body is important to prevent shorting out any electrical components of the furnace. To ground the static electricity from the body, before doing any work on the electrical components, touch a metal object away from the furnace. The current will move from the body’s point of contact to the metal surface. This happens because metal is a better conductor of electricity than the human body.control board

 

Once the electricity is discharged from the body, working on the furnace is less dangerous to the electrical parts.

Basic HVAC home troubleshooting

H1: Basic HVAC Heating and Cooling System Troubleshooting

Your home heating and cooling system is a vital piece of your home that makes sure you and your family can feel comfortable year round. If it isn’t maintained properly, you run the risk of your system becoming less efficient that will not only wasting costly energy, but make it difficult to maintain that perfect, comfortable environment in your home.  When something goes wrong, there are a few common things to check in the HVAC system for some quick troubleshooting.

H2: Time to Swap Filters

A filter that is full of dirt and dust cannot properly move the air your HVAC system needs to operate efficiently. Even if the air still is flowing, the mechanics of the system might be working harder than they need too, prematurely aging your equipment. Plan to change your filters once a month in high-use seasons and every three months the rest of the year.

H3: Thermostat Is BrokeniS30

If your house is suddenly too hot or too cold and nothing seems to be wrong with the HVAC equipment, the culprit might just be your thermostat. Fortunately, this is a simple and relatively inexpensive repair to make.  Make sure that you check the status of your thermostat and see if it’s functioning properly before you start looking into other pieces of your system or planning a bigger repair project.

 

H4: Tripped Breaker

HVAC equipment that is completely unresponsive might throw you into a panic, but the reason might just be a tripped breaker. Be sure to immediately check out your breaker panel before doing anything other detective work. Flip the appropriate breaker back to the “on” position. That should get your system back up and running unless there was another problem inside your system.  It is possible that a breaker switch could be a fluke, but if the breaker continues to trip, contact a professional to help you address what may be causing the issue.

H5: Unbalanced Dampers

Dampers in your home heating and cooling ducts restrict the airflow into any section or room. If it seems like a particular space is always too cold or too warm, you might need to adjust the dampers that lead to that room.  If adjusting the dampers doesn’t completely solve the issue, you may have another issue on your hands.

H6: Leaking Refrigerant

If your home cooling system doesn’t seem to be producing air that is as cold as expected, you might have a problem with refrigerant leaking from the AC unit. If so, you will need to call a professional out to reload the system and repair any leaks.
