To make sure you get the one that’s perfect for your home, build your system according to what’s most important to you:
comfort, efficiency, quiet operation or extreme reliability.
For greater efficiency, look for:
- Products with efficiencies no less than:
- 90% AFUE for furnaces
- 15 SEER for air conditioners
- 9.50 HSPF for heat pumps
- ENERGY STAR® qualification
- Variable speed motors
- Multi-stage operation
- AHRI-matched systems
For greater comfort, look for features such as:
- Variable speed motors
- Reduce hot and cold areas throughout the home
- Improve year-round humidity control
- Improve indoor air quality; helps reduce dust and other allergens because of constant air movement
- Lower monthly utility bills*
- Multi-stage operation
- Rather than being "all on" or "all off," your furnace can adjust its heat output based on conditions
inside and outside your home.
- Get two air conditioners in one—high-efficiency
products with multi-stage compressors will run on the first stage of cooling when temperatures are
mild. The equipment will use less energy more often.
- When outdoor temperatures reach extremes, the equipment will utilize the additional stage, but will
still operate efficiently because of the higher SEER
rating.
- Lower monthly utility bills*
For the quietest operation, select the following:
Heating
- Products featuring Quiet Combustion technology
- Small Btu inputs per burner
- Gradual start-up avoid whoosing air and duct work “popping”
- Insulated cabinets
Cooling
- Products with Sound Reduction Technology
- Advanced fan blades
- Heavy-duty sound blankets
Heat Pumps
- Products that include QuietShift™ Technology
For the greatest reliability, look for:
- Armstrong Air EHX heat exchanger
technology
- Made of stainless steel for corrosion resistance and maximum strength against thermal fatigue
- Longer heat exchanger life
- Specially shaped surfaces to direct airflow more efficiently, and transfer heat more effectively
- Armstrong Air MHT™ cooling
technology
- Specially designed fan shroud for optimal air flow over the coil
- Louvered coil fins have more surface exposure for greater heat transfer
- Rifled refrigeration tubes
- 10-Year Limited Warranties on parts
- Lifetime Limited Warranties on the heat exchanger
