How does an air conditioner work?

Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.

What does it mean when my A/C freezes up?

What should my thermostat be set to at night during the cooling season? Normal temperatures in the summer can fluctuate depending on the region. If the thermostat is set at the desired temperature during the day, consider a 10 degree lower temperature at night. Most automatic thermostats have intelligent recovery which enables the thermostat to lower the temperature gradually, so the night time savings is not lost by manually bringing down the temperature all at once. These programmable thermostats also help to optimize energy savings without sacrificing comfort.

What size air conditioner do I need? Every home is different, and there are many environmental variables that must be taken into account. There is not a set size that can be recommended without a Heating and Cooling Load calculation. New higher efficiency A/C systems need proper airflow to meet their designed efficiency levels. A load calculation must be performed on the home to determine the proper system size that meets all the physical requirements. Ultimately the size determination should be made by a qualified air conditioning specialist.

What do all those air conditioner and heat pump ratings mean?

Efficiency Ratings: SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate.

HSPF (Heating Seasonal Performance Factor) is a measurement similar to SEER, but it measures the efficiency of the heating portion of a heat pump.

What is a heat pump?

A heat pump is an efficient method of cooling your home in the summer and warming it in the winter. Although heat pumps are new to many people, they have been around for decades. A heat pump looks like an air conditioner, but that's only the outside appearance. It actually has two functions based on the same principles for both. In warm weather situations, the heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses, collecting heat from the outdoor air and transferring it inside your home.

Even when the air outside feels extremely cold, the air still contains some heat. The heat pump pulls the heat from this cold outdoor air and sends it inside to warm your home. When there is not enough heat in the outside air to meet the demand of the thermostat setting, an electric heater supplements the outdoor air to warm the home.

While many people find the winter operation of a heat pump the most difficult to understand, it is during the heating cycle that the heat pump produces the most savings. Unlike a furnace that turns fossil fuel or electricity into heat, the heat pump collects heat that already exists in the outdoor air by means of its refrigeration cycle. Consequently, a heat pump will produce two to three times more heat than the energy it uses.

In addition, a heat pump can be an effective add-on option to use in conjunction with an existing gas furnace. With a dual-fuel system, the two systems share the heating load but never function at the same time. Each system operates when it is most cost effective. The heat pump will be the primary heating and cooling system. However, when the temperature drops below the heat pump's ability to operate as efficiently as the gas furnace, the gas furnace will take over until the temperature rises enough for the heat pump to operate more efficiently.

Why does my air conditioner keep running? More than likely the air conditioner is undersized and/or working harder to keep to the desired indoor design temperature. An air conditioner works properly and efficiently at the temperature it was designed to achieve during installation. If there are hotter than normal days, the A/C will try to maintain the indoor design temperature. This does not necessarily mean there is an undersized unit. It means that the particular hot day is outside the normal range of the calculated design for the A/C unit. A proper load calculation from an air conditioning contractor can determine if the air conditioner is properly sized for the geographic location.
