Furnaces - all furnaces are 2-stage. Staging refers to heating ability by allowing the furnace to run some of the time at a lower BTUh. We are able to provide a better control of the temperature (i.e. doesn’t get so cold before it goes off) and generate a smaller fuel bill each month.

Blower Typers-
Standard- a regular multi speed direct drive motor
Variable speed ECM Electrically Commutated Motor- a brushless DC drive motor this ¼ century old technology is rapidly gaining popularity with the average home owner due to its increasing affordability, electrical efficiency (costs the same as an 80 Watt light bulb to run continuously) and amazing homeowner comfort. This also helps to accentuate the effusiveness of air purification/filtration systems.

AFUE- for every dollars worth of gas how many pennies of heat do you get into your home 80, 95, 96? (See hybrid systems for much higher efficiencies)

Furnace Types
    80% 2-stage (staging furnace controlled) Standard Blower
    80% 2-stage (staging thermostat controlled) Variable Blower

    95% 2-stage (staging furnace controlled) Standard Blower
    96% 2-stage (staging thermostat controlled) Variable Blower

Heat Exchanger - The part that keeps the fire/smoke separate from the air in your house.
    Primary- Tubulor 409 Stainless Steel
    Secondary- Stainless Steel

Product Warranties

Furnace- parts- 10 years
    Heat exchanger- Lifetime to original owner and 20 years thereafter until replaced
    Labor- 5 years/10 years available
Air Conditioners or Heat Pump- parts- 10 years
    Labor- 5 or 10 years
    Compressor- 10 year or lifetime (20 years to successive owners)
13 seer has 10 year compressor
All others have lifetime compressor

Unit replacement means that if the heat exchanger or compressor fails within its warranty period the entire furnace or outdoor unit will be replaced with the balance of the parts and compressor/heat exchanger (i.e. if the unit fails 8 years after install, the unit is replaced but the parts on the replacement unit have the warranty of the 10 years from original install. In this example 2 years left.)

    Customer pays for labor to install new replacement unit

Air Conditioners-
    Staging- having 2 cooking capacities in 1 unit
A 3 ton unit will run as a 2 ton unit if it is capable of providing sufficient cooling while using less electricity. This provides a greater control of the temperature and a lower utility bill.

Tons- the amount of cooling or heat removal a unit is capable of. There are 12,000 BTUh in a ton. Ductwork should typically be designed for 400 cfm (cubic feet per minute) per ton in our climate.

Sizes- 1 ½           2       2 ½         3         3 ½         4          5
