Your furnace is the main factor in keeping your home comfortable during the winter.  If you have central air conditioning, it is also a major component in keeping you comfortable during the summer, as the blower in your furnace uses the same ducts to blow cool air throughout your home during the cooling season.

MOUNTAINWEST WILL KEEP YOU COMFORTABLE BY:

Installing a new efficient Bryant, Lennox or Payne furnace
Repairing your existing furnace
Installing a complete system for your home remodeling needs
Designing a system based on your individual needs
Building custom ductwork

Call Mountainwest 801-936-2020 today for more information about your existing furnace or a new one. We will answer your questions to help determine your system's needs.

HOW EFFICIENT IS MY CURRENT FURNACE?

It is relatively easy to get a good idea of how efficient your furnace is, just by determining what the flue (or vent) pipe is made of.   The flue is the pipe the transports the exhaust gases from your furnace to the outdoors.  It will either be a metal pipe (galvanized or aluminum) that is 4 to 6.5 inches in diameter, or a PVC (white plastic) pipe that is 2 to 3.5 inches in diameter.  If the flue is PVC there will usually, but not always, be a second identical pipe that brings fresh air in from the outdoors.  These pipes will always attach directly to the furnace itself.  They will never attach to the rectangular air ducts.  Discount the other pipes attached to the furnace, which will all be one inch in diameter or smaller.  If the flue is metal the furnace efficiency is no greater than 80%.  If the flue is PVC it is between 90 and 96% efficient.

WHAT IS A TWO-SPEED FURNACE AND WHAT ARE ITS BENEFITS?

Traditional furnace designs typically have a single heating capacity (output) capable of keeping a house comfortable under the most demanding conditions.  This capacity is used regardless of changes in weather conditions.  Because the capacity is fixed, the furnace run time changes as the weather changes.  In warmer weather the furnace tends to run for short periods of time, but in very cold weather, the furnace runs for longer periods of time.  The ON-OFF cycling of a furnace is controlled to limit the temperature swings that affect occupant comfort.  Byant offers furnaces capable of operating at two different capacities.  In addition to the full capacity necessary to handle the coldest weather conditions, these two-speed furnaces offer a reduced capacity stage that can be used in the milder conditions that predominate during most of the heating season.  The reduced heating capacity is 65% of the maximum capacity.  The circulation air blower incorporates an advanced type of motor that maintains its efficiency at low speed (as described below).  Because most furnaces have some reserve capacity, a two-speed furnace will operate at its lower capacity most of the time.  Low-speed operation has several advantages, including reduced temperature swings.  Comfort can be improved by maintaining a more consistent temperature in the conditioned space.  The airflow rate is lower at the reduced capacity, which tends to reduce drafts while reducing blower and duct system noise.  In addition, the advanced blower motors use less electricity than single-speed units because of the increased efficiency of the blower motor and because significantly less power is required to move air at lower flow rates.  Of course, the furnace’s full capacity is always available for unusually cold weather or for rapid recovery from thermostat setback periods.  Thus, two-speed furnaces offer all of the capabilities of single-speed units with the added potential for improved comfort, reduced noise, greater system flexibility, and increased efficiency.

WHAT IS A VARIABLE-SPEED FURNACE AND WHAT ARE ITS BENEFITS?

A variable speed furnace has all the comfort and efficiency qualities of the two-speed furnace and much more. A variable speed furnace has a motor that will run from extremely slow to full speed and numerous speeds in between.  Don’t confuse a variable-speed motor with a multi-speed motor, which will typically have three or four speeds and is the motor that has been used in almost all furnaces since the mid 1980s.  This motor also runs on 1/5th to 1/6th the electricity required by a multi-speed or standard furnace motor.  This equates to about the same power required to operate a 75-100 watt light bulb, resulting in hundreds or thousands of dollars in saving over the life of the furnace.  The motor can sense its own speed and make adjustments based on the which part of the heating or cooling cycle it is in, resulting in greater efficiency and comfort and quieter operation.  It can also detect a dirty filter and speed up to counteract the increased friction of the filter, resulting in more comfort and greater efficiency.
A variable speed motor also is more efficient at circulating air evenly throughout the house.  This results in great levers of comfort, as there will be less temperature differential between different rooms and different floors of the house.
