The most common source of heating in Utah is a natural gas fired furnace.  Due to the relative cheap operating and low maintenance costs, natural gas fired furnaces are a great heating source that have an average life span of about twenty years.  The most difficult decision for you the home owner is trying to select the best gas fired furnace for your home.  Several factors can play a role in this decision such as currently installed equipment, how long you intend on remaining in the home, if you have finished the basement or planning to in the near future, current finances, and other house specific factors.  Furnace manufacturers offer everything from your basic builders grade on/off single stage furnaces to high efficient modulating gas and modulating blower furnaces with all of the bells and whistles.  Equally important is the mechanical contractors responsibility to size the correct amount of heat (BTUH rating) and airflow (CFM) which will be required to maintain a comfortable living space within your home.  It is vital that you can trust the mechanical contractor who is advising you when making these decisions, way too often we get service calls for hot and cold spots, cooling coils which are icing up, and general comfort complaints which almost always lead back to poor decisions or bad mechanical contractor advise given when selecting a new gas fired furnace for your home.  TNT Mechanical has the knowledge and expertise to help you navigate all of the different equipment options and sizing requirements so that you can make an informed decision and ensure you get the best equipment possible for your home.
