Getting to know your HVAC System
- Humidifier - maintains the proper level of moisture in your home, which alleviates dry skin and allergies and helps with static electricity
- Evaporator Coil - allows refrigerant to absorb heat from the air as it passes over the coil surface.
- Furnace - heats and circulates air throughout a home’s ducts. Available in both gas and oil based models.
- Air Cleaner - improves air quality by removing harmful and irritating airborne pollutants from your home.
- Thermostat - the control center of your heating, cooling and air quality system.
- Air Conditioner - efficiently cools the air inside of your home.
- Heat Pump - provides reliable, energy efficient heating and cooling.
- Ventilator - combines fresh outdoor air with conditioned indoor air for improved air quality and maximum efficiency - great for today’s tightly constructed home.
- Zoning - gives you the ability to set different temperatures for up to 8 different areas of your home for truly customized comfort and enhanced utility savings.
Get Familiar with HVAC Terms & Technology
- AFUE (Gas Furnace)
- Annual fuel utilization efficiency measures heating fuel usage. The higher the AFUE rating, the more efficient the unit.
- BTU (Heating Capacity)
- British thermal unit represents the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
- SEER (Air Conditioner)
- Seasonal energy efficiency ratio measures cooling efficiency in air conditioners and heat pumps. The higher the SEER, the more
efficient the unit.
- Ton (Cooling Capacity)
- A ton is the cooling capacity of an air conditioner. One ton is equal to the amount of heat required to melt one ton of ice in a 24-hour period.
- HSPF (Heat Pump)
- Heating seasonal performance factor measures the heating efficiency of a heat pump. The higher the number, the more efficient the unit.
- MERV (Air Filtration)
- Minimum efficiency reporting value measures the efficiency of air filters.
Air Conditioner Performance
- Two-Stage / Single-Stage Compressor
- Two-stage compression performs at two levels or capacities of operation; low and high. The system is designed to perform at the low level most frequently to allow for quieter operation, greatest efficiency and best dehumidification. During extremely hot weather conditions, the system will perform at high capacity operation in order to keep up with cooling demands of the home. A single-stage compressor performs at a single level of operation and is either off or on.
- Variable-Speed Compressor
- Variable-speed compressors operate at five levels or capacities of operation. The ability for a compressor to step up or down in 5 stages means that the system is capable of delivering the most superior perfomance in terms of quiet, humidity control, consistent temperatures and unprecidented energy efficiency.
Gas Furnace Performance
- Two-Stage / Single-Stage Gas Valve
- Much like a two-stage compressor, a two-stage gas valve also performs at two levels or capacities of operation. The heating system will either perform at a high-level of operation when there is a significant call for heat or in a more energy efficient, low-level of operation when maintaining indoor temperatures. A single-stage gas valve performs at a single level of operation and is either off or on.
- Modulating Gas Valve
- Unlike single and two-stage gas valves, a modulating gas valve adapts its output to the precise needs of the home with tiny 1% adjustments between 40-100% capacity. Modulating furnaces operate with more finesse to reduce temperature swings, provide consistent indoor temperature, quiet operation and superior efficiency.
- Variable-Speed Blower Motor
- A variable-speed blower motor automatically adjusts the flow of warm or cool air circulating throughout the home for maximum comfort control. Variable-speed systems are great for boosting HVAC system efficiency and improving summer dehumidification.
