An internal blower or fan pulls air into the furnace where it absorbs heating energy as it passes across the heat exchanger cells. The blower fan simultaneously forces the newly heated air through your home's ductwork and out into your living areas. A properly sized furnace for your dwelling house has enough heating capacity, every bit measured in British thermal units per hour (BTU/h), to provide heating comfort throughout your home.

Authentic sizing is important for comfort, energy efficiency and the lifespan of the heating and cooling system because:

An oversized furnace heats the space rapidly, causing information technology to cycle on and off too oftentimes. The constant on-off cycle is inefficient, can bulldoze upwards operating costs, and can add together wearable-and-tear to central components which tin potentially shorten furnace life.
An undersized unit volition not fairly heat the abode and will run continuously, which can waste energy and money.

When the discipline, "how large a furnace do I need" comes up with your local Carrier HVAC expert, it is usually in reference to its BTU rating. BTU stands for British thermal unit and represents the amount of heat needed to raise one pound of h2o one^⁰ Fahrenheit. Furnace size or capacity is expressed in BTU/h, or the corporeality of British thermal units the furnace can generate per hour.

Choosing the correct size furnace for your home is important considering an undersized furnace won't generate plenty heating capacity to proceed your habitation warm. Information technology volition run constantly to go along up with demand. An oversized furnace will frequently turn on and off because information technology is supplying too much heat, which creates uncomfortable, up-and-down temperature swings and reduced efficiency. Your local Carrier dealer is experienced at computing furnace size and will practise what'southward called a "load calculation" to determine the size most appropriate for your home. Typical residential gas furnaces will be bachelor in diverse sizes between 44,000 BTU/h and up to 120,000 BTU/h.

Agreement Furnace Efficiency Ratings

Once your Carrier dealer has completed a load adding to determine the proper size furnace for your home, yous still have decisions to make. That's because ii furnaces with the same heating capacity can accept different efficiency ratings. Furnace efficiency ratings are expressed in terms of AFUE pct and volition exist displayed on the furnace with the yellowish Energy Guide label. AFUE stands for "annual fuel utilization efficiency". Furnace AFUE represents the per centum of heating energy from the fuel source that is converted to estrus your domicile. It is calculated by taking into account the furnace'southward total heating output over a yr'southward fourth dimension in human relationship with the amount of fuel used over the same amount of time.

Dissimilar heating fuel sources have slightly different requirements, merely natural gas furnaces, the most normally used across the United States,^[ane] are required to deliver a minimum of 80% AFUE. The highest per centum efficiency models tin achieve as much as 98.five% AFUE. When looking to buy a furnace, yous can identify the higher efficiency models by looking for the Energy STAR^® logo. Energy STAR standards are slightly different for each fuel source.

Additional Factors to Consider

As a rule of thumb, the number of square anxiety in your abode will exist used, forth with the BTU furnace rating, and average outdoor temperature in your area. Nonetheless, there are additional factors that should exist considered, which include:

Home insulation in attics, roof and walls
Additional heat-generating sources such as woods-burning stoves and fireplaces
Quality of ductwork
Number, size and location of windows and doors
Orientation of home, number of "exposed" walls
Open up floorplan vs. many isolated spaces
Climate zone

As you may have noticed, not all of the factors involved are a affair of getting out a record measure and jotting down some dimensions. There volition be a bit of estimating that goes into a load calculation, and that's another reason why selecting an experienced HVAC contractor makes so much sense.
