Through The Eyes of a Technician

Wednesday, October 24th, 2012

For me, the dangers surrounding gas fired appliances and exhaust are very real. When I was just six years old I lost my mother to carbon monoxide poisoning. I still struggle with this loss each and every day.  I will never forget that day and what happened or how it has changed the course of my life. While there is nothing I could have done as a child to change any of it, I must tell you of the joy and great sense of pride and purpose it gives me to work with Lanz Heating and Cooling to help educate others now of these dangers. I feel it gives me a chance to pay it forward in a sense and use my knowledge and past experiences to help all of you. I often think back to the first time I felt like I really made a difference while working for Lanz Heating and Cooling.

Early in my career as a technician I met a couple that had transferred to our campus for work from the Atlantic coast. The wife  had been sick for the entire three months in our great state. Not knowing why, they went about their business but did set up an appointment to have the furnace in their home maintained.  Routine maintenance showed everything to be okay and I would guess a very large number of HVAC companies would have given it the okay not knowing there really was a problem because everything was functioning properly. The end result of this story is why we here at Lanz don’t just look to make sure it’s “operational.” There is so much more to it than that. Upon further investigation I found several rings to have popped off the heat exchanger causing it to not draft properly and allow these toxic fumes into the home. THIS had been causing her to be sick! She had been to the doctor multiple times and tried many over the counter medicines for her symptoms. Once we shut down her furnace and replaced the heat exchanger the headaches stopped. The other symptoms went away too. I felt I had truly helped them and I could tell they felt that way too.

I realize there is nothing more frustrating than coming home from a hard day of work or waking up in the morning only to find your home is super hot or freezing cold. Those calls to the service companies are always difficult. It gives me satisfaction  seeing the relief set in for the homeowner and the shoulders begin to lighten once they realize that we have taken care of everything. But fixing it is not enough. You need to know that we truly care about you and your family’s well being. This is why we don’t just come out to fix the problem. There is so much more going on in your home than just that box that sits in your basement or mechanical room.

My name is Jake Farmer and I am a NATE Certified residential technician at Lanz Heating and Cooling. It is an honor to serve you and I sincerely appreciate each and every encounter with all of you, from those I have seen every season for the past few years, to those I will meet tomorrow. Thank you for the opportunity to take care of you and your family.

How Much Electricity Does a Urbana Gas Furnace Use?

Monday, April 9th, 2012

The answer to the question “How much electricity does a gas furnace in Urbana use” could sound like the lead-in to a silly Groucho Marx joke: “None, because it’s a gas furnace! HONK!”

In fact, electricity is necessary for several important tasks as part of the more efficient gas furnaces.

Lighting the Torch

Gas is the fuel that fires the flame that heats the air that warms your home, but electricity is the spark that lights the gas.  The flame is not roaring all the time or just ignites spontaneously.  Think of the athlete igniting the Olympic torch.

A low voltage electric signal from the thermostat opens the valve that controls the amount of gas flow and therefore the flame.  A solenoid coil in the valve senses gas and ensures flame to prevent an explosion or leakage, then opens wide to let the heating begin and shuts down when the desired temperature is reached.

Blown Away

All that heated air must be moved through the ductwork and distributed room to room to create the comfort and this is done by a motor-driven fan which is the largest use of electricity in a gas furnace.  The motor turns on and shuts down according to the relationships between flame, heated air and the thermostat setting.

Known as a draft inducer, a second fan is employed to remove the toxic fumes that are the residue of the burned gas.  These fumes which can be deadly are usually pushed through a PVC pipe to the exterior and released safely into the atmosphere.

Sum Total

The amount of electricity used to ignite the flame is very small, phased through a low-voltage impulse wire, nearly too small to even show on your meter.  Most of the electrical energy contributing the critical role of powering the two fans in gas furnaces adds up typically to less than 600 watts at any given time or about the same as a few light bulbs.

While gas furnaces are much more efficient and less costly than any kind of electric heat, they are useless (and even dangerous) without that little bit of electrical help.  Call Lanz Heating & Cooling with any questions.

Pros and Cons of Various Heating Systems in Longview

Friday, February 3rd, 2012

When it comes time to install a new heating system in your Longview home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.  Contact Lanz Heating and Cooling with any questions about your heating options.
