How Does your Furnace Work?
When you hit the market, you’ll find different types of furnaces in San Antonio. Older series of furnaces were powered by coal, but the modern systems make use of electricity, natural gas, and propane to heat your home. Most American homeowners, however, prefer the natural gas or electrically powered furnaces.
A furnace is essentially a combination of appliances, with functions interconnected to regulate the temperature in your apartment. Most commonly used systems have the basic furnace and thermostat combination. A thermostat reads the air temperature in your space and then engages the furnace anytime the temperature falls below the required level.
When natural gas or propane-powered furnace turns on, fuel is drawn into a series of burners located in the combustion chamber. The heat generated is transmitted to the heat exchanger, which warms the air a lot more efficiently than burners. A furnace is also designed with a blower to help circulate the warm air in a building through a network of ducts.
In the case of electric furnaces, a thermostat calls for heat, and this triggers electricity to be sent to the tightly wound conductive coils. Air that passes through the hot coils will be warmed and pushed back into the rooms through the ventilation system.
How Long will a Furnace Last?
The lifespan of furnaces usually varies, depending on how well they are used and maintained. With proper routine care and on-time repairs, expect your furnace to last for about 15 years. While some types can surpass this mark, they often lose some level of efficiency and become prone to frequent repairs that can be quite costly.
You should consider replacing your heating system if it’s close to this age or when you notice the cost of furnace repair in San Antonio is more or less half the price of a brand new furnace.
How Much will a Furnace Cost?
Several factors go into play when determining the cost of furnaces in San Antonio. The most common ones include the furnace size, brand, available features, the efficiency of the unit, warranties included, and complexity to install.
On average, the cost is estimated to be anywhere between $1,700 and $6,300. The average cost of electric furnaces range from $700 to $2,450, gas furnaces cost $1, 200 to $3,900, and oil furnaces attract prices between $1,900 and $6,300.
You also need to factor in the installation cost, which typically ranges from $500 to $1,500.
Please keep in mind these are just average estimated cost of furnaces, so they are not guaranteed.
