Since the minimum efficiency regulation changed to 13 SEER in January 2006, most OEM systems now incorporate a thermostatic expansion valve (TXV) style metering device as the standard for air conditioning systems. It is now extremely important for the HVAC technician to understand the design and operation of this type of valve.
You might have read or heard about geothermal heat pumps and how they’re gaining a lot of popularity. But what does “geothermal” mean and how does this system work? Geothermal heat pumps work along the same principles as standard air conditioning or heat pump systems with a few exceptions.
Because air conditioning systems tend to last for more than a decade most people don’t have a need to keep up with the latest trends. But today’s available systems may be more sophisticated and efficient than the one currently in your home if it is more than 6-8 years old.
If you have to replace a system the first thing most people think is, “give me the same thing I had.” In most cases whatever size you had before will work for the replacement system, but there are circumstances where it will not.
One of the easiest ways to save money on your energy bill is to stop cooling or heating your home when no one is there. The easiest way to do that is by using a programmable thermostat. Rather than waking up to a chilly house, or walking in after work to a home that feels like an oven, a programmable thermostat allows you to control when your home needs to be cooled or heated, and when it doesn’t.
Window air conditioners (sometimes called ‘room air conditioners’ or ‘window units’) are small AC units that are installed through the windows of the room you are trying to cool. Because they can be purchased at many retail locations, they are relatively inexpensive and fairly easy to install without a contractor. They can appear to be a good option for the budget-conscious consumer.
The choice of a contractor is an important decision and shouldn’t be made quickly or without due diligence. Finding a contractor who can become a real partner in the maintenance of your home’s HVAC equipment can be invaluable for years to come.
