We’re getting the first cool weather of the season here in Orange County, which brings some relief from a long, often extremely hot summer. Now is when you’ll turn on your electric furnace for the first time in… well, we wouldn’t even want to guess how long. 

Because your electric furnace has sat unused for a long time, you might feel nervous when you have to turn it on. Maybe it won’t work? And if it does work, how long will it continue to heat the house?

Okay, as the post title makes clear, we’re here to talk to you because your electric furnace isn’t working. You may need our technicians for furnace repair in San Juan Capistrano, CA. But first, let’s take a look at why an electric furnace might be giving you trouble. It’s possible there’s a simple issue you’ve overlooked.

What Is “Too Old” for a Furnace?

Furnace-standard

No furnace can last indefinitely, and there’s no such thing as “the last heating system you’ll ever need to buy.” Even in warm Southern California, furnaces gradually wear down from use. In fact, homeowners often neglect to have routine service for their furnaces because they don’t rely on them often. This will speed up the furnace’s decline.

If you’ve come to this post, it’s because you suspect your furnace is past its expiration date—whatever that may be. What is considered “too old” for a furnace? We’ll take a look at this question, which has several answers.

The Truth About Electric Furnace and Gas Furnace Efficiency Ratings

Monday, October 21st, 2019

twenty-dollar-bill-foldedFall is the usual time for homeowners to make changes in their central heating systems. Even in sunny Orange County, where the only snow we see is on the distant peaks, a central heating system is necessary for homes that often get drafty on the winter nights. Sometimes the upgrade for a heater is to buy a new one.

If you’re home is like most, you use a furnace for central heating. The two common types of furnaces people use are natural gas furnaces and electric furnaces. You might not face a choice about which type of have—if you don’t have a natural gas line, you definitely won’t get a natural gas furnace! But when you do have to make a choice, be careful that you don’t make the mistake about furnace efficiency ratings that has often misled customers into making the poorer system choice.

Is an Electric Furnace the Best Choice If My Home Doesn’t Use Gas?

Monday, January 14th, 2019

question-mark-badgeThe use of natural gas is widespread, but it isn’t universal to all homes in Orange County. Some homeowners prefer not to use natural gas at all because of concerns about safety. Of course, it’s easy to operate a home entirely through electricity—but it can present a few tricky questions when it comes to an appliance like a heating system. Homes with natural gas will almost always use a gas furnace—it’s simply the most powerful and most energy efficient option. There are also gas boilers, but these are less common in Southern California.

The heating option for all-electric homes that most commonly springs to mind is the electric furnace. Is this the best choice, however? Well, like so many things in life, it depends.

What is an Electric Furnace? A Question from Foothill Ranch

Wednesday, November 23rd, 2011

There are many types of furnaces available in Foothill Ranch that use a variety of energy sources to operate. Gas furnaces use natural or propane gas, boilers and radiators use water, heated by electricity. And then there are electric furnaces, which may have an advantage over other energy sources based on energy costs.

Simply put, electric furnaces function through the use of electricity. They do not require the use of any type of fuel – but function through wires and chords. An electric furnace uses heating coils, sometimes referred to as “resistance calrods” to create heat directly in the air flow. Inside the furnace cabinet are controls, a blower, and the circuit breakers for the heating elements. Some furnaces have the breakers accessible from the outside of the cabinet.

Other add-on accessories may include an electronic air cleaner, air filter, humidifier, high performance media filter, and air conditioning evaporator coil.

The heating process begins with the home’s thermostat. A drop in temperature is sensed by the thermostat, which alerts the electric furnace. The coil then warms up, thanks to the electric current that passes through it. The heated coil in turn heats the temperature of the air around it, which is then blown into the house through a blower. The pressure that is exerted by the blower on the heated air, warms it further. The blower is able to overcome the resistance of the duct work and replace unheated, colder air with the heated air. In most homes there are various return air ducts that are used to bring in the colder air to the furnace. This cold air travels through the furnace, through an air filter, the blower, and finally through the heat exchanger. After this it will then be pushed back into the house as warm air.

To maintain a supply of fresh air in the house, some furnaces also suck air from the atmosphere outside. After the air in the house reaches a particular temperature, the thermostat automatically shuts off the electric furnace.

An electric furnace may be less costly to run, depending on the price of electricity versus other sources like natural gas, propane gas, or oil. Gas and oil are fossil fuels and burning them leaves a “carbon footprint” – the release of carbon compounds and gases into the atmosphere. An electric furnace does not burn fuel and thus does not leave a carbon footprint. This electric warming process results in fewer particulates and contaminants in the air, too.
