Get Your Gas Furnace Maintained Soon

Monday, January 8th, 2018

furnace-maintenance-sessionsMost heating systems in the area are gas furnaces, which are inexpensive and easy to keep running. They make a good fit for our warm weather and can provide reliable heat this time of year, when nighttime temperatures take a dip.  Unfortunately, because our weather is so hot most of the year, homeowners tend to focus on their air conditioning systems, leaving their gas furnaces to suffer from slow neglect. Repair issues have a way of cropping up without warning in such scenarios, leaving you scrambling to get the system fixed just when you need it the most.

We can provide timely repairs for your gas furnace when called upon to do so, but we also believe that an ounce of prevention beats a pound of cure. That means that furnace maintenance sessions make a better way of dealing with your heater’s problems than waiting for a breakdown and rushing around. Ideally, you should schedule one once a year, and if it’s been more than 12 months since you last one, now is an excellent time to make an appointment. Here’s a quick look at how it works.

What Is a Thermocouple?

Friday, January 30th, 2015

Every combustion heating system needs a number of safety mechanisms to ensure that the unit runs safely. One area that has to be highly monitored with both furnaces and boilers is the pilot light. In a furnace that has a standing pilot light, the component responsible for monitoring the pilot is known as a thermocouple.

What It Is

A thermocouple is an instrument made from two differing metals; these metals are soldered together at a single point for the purpose of monitoring temperature. When the metals are heated at the point of contact, a voltage is generated; this is known as the Seebeck effect. As the heat on the metals increases, the voltage also increases; the voltage coming from the thermocouple is what indicates to your furnace that there is a pilot and that it is viable and good for lighting your furnace. The thermocouple is placed so that the point of contact, which is encased in a stainless steel encasement, is right in the flame; this is so the thermocouple can accurately measure the pilot.

How It Works

The thermocouple not only measures the standing pilot flame, it also acts as a gatekeeper to the gas line valve. When your thermostat calls for heat, the thermocouple checks the pilot light; if there isn’t a pilot light, or the flame isn’t strong enough, the thermocouple won’t allow the main gas valve to open. This helps ensure that gas won’t flow unless it can be lit. If the standing pilot is viable, the thermocouple allows the main gas valve to open and your furnace’s burner is successfully lit.

Common Problems

Thermocouples are exposed to very high temperatures, and then cool off; this kind of prolonged wear and tear can cause the thermocouple to crack. Additionally, the metal strips can corrode, which also cause operational issues. A dirty thermocouple may not be able to accurately read the flame, and a thermocouple that shifts position or is positioned incorrectly will be too far away to correctly read the flame. Any of these problems can result in ignition problems with your furnace.

The safety mechanisms on your furnace are critical; as such, they should only be repaired by professionals. Having problems with your furnace? Call A–Professional Heating and Air Conditioning today and schedule an appointment with us! We offer quality furnace repair services in the Hammond area.

Reasons to Consider an Electric Furnace

Wednesday, January 14th, 2015

Fossil fuels are so prevalent that it seems like everyone has easy access to them, but this isn’t true. Many rural areas do not have natural gas lines, and some people simply prefer not to use fossil fuels. Not too long ago these things would have prevented the installation of a furnace, but today’s electric furnaces offer homeowners another choice when it comes to furnace installation.

How Does an Electric Furnace Work?

Electric furnaces use a component called a heating element to generate heat. Heating elements have a number of tightly-wound metal coils that, when electrified, become red-hot and generate heat. When the air around the heating elements reaches the right temperature, the furnace’s blower turns on and pushes the warm air into the ductwork for dispersal into your home’s living spaces.

Why Consider an Electric Furnace?

As mentioned above, not everyone has access to a natural gas line – but one thing just about everyone has access to is electricity. If you have ductwork in your home, but do not have natural gas, you have the option of installing an electric furnace. Electric furnaces have come a long way over the years, especially in terms of energy efficiency. In fact, because electric furnaces do not lose any fuel to combustion byproducts, there are many electric furnaces that have an AFUE rating of 100%. Another reason to consider the installation of an electric furnace is lifespan. The average lifespan of an electric furnace is 20-30 years; comparatively, the lifespan of a combustion furnace is 15-20 years. Lastly, electric furnaces are very clean because they do not consume fossil fuels; this means you don’t have to worry about soot and ash around your unit.
