EFFICIENCY LEVELS: HVAC... air conditioning equipment must meet both the SEER and EER to qualify. “If it meets 13 EER, it will automatically meet 16 SEER. But not the other way around,” he says.
FURNACE CHOICE: ...the 95% efficiency level for a gas furnace is easiest to reach, but it’s not always the best choice, based on climate. “In the northern states, [clients] get their money back sooner, but for southern states, A/C or heat pumps are better.”
SYSTEM COMBINATIONS: Contractors need to install the right combination of HVAC equipment to meet the efficiency levels. For example, matching the A/C condenser outside with the right furnace or air handler inside.
SPACE CONSIDERATIONS: John Hurst, vice president of product management with Richardson, Texas–based Lennox, says that many product installations have space constraints, particularly for the furnace and air handler. Local codes governing chimney size for venting and make-up air will also affect installation parameters. Frederick Air sales manager John Poyle offers an example: “If my house has a 3-ton air conditioner, and I want a 20 SEER unit, a manufacturer will say, this unit comes up to 20 SEER. But I may need a 5-ton coil to get that 20 SEER efficiency from the unit. But that coil is massive and won’t fit in my basement because of the low ceiling.”
To choose the best solution for the customer, make sure that the HVAC contractor reviews existing conditions, including the orientation of the house, shading, and existing insulation, as well as lifestyle considerations such as how the customer uses the system and what changes they plan for the future.
