The Danger of Skipping Your Furnace Maintenance

If you have a gas furnace in your Houma or Thibodaux horne, you know how much of a blessing it can be. It provides reliable heating for your home during to cold winter months, and does so more efficiently than a heat pump can.

But you also know that goes appliances have certain risks associated with them. Those risks include fire and gas leaks, and most dangerous of all, carbon monoxide.

As a gas furnace owner, the most likely risk your furnace will pose is the development of cracks in your heat exchanger.


How Do Cracks Develop In Your Heat Exchanger?


Because the heat exchanger is the part of the furnace that creates your home’s heat, the most likely reason for it to crack is simple wear and tear. This happens when combustion gases from the furnace burners enter the heat exchanger and heat up its metal walls, thereby heating the air passing through the unit.

As these combustion gases work their heating magic, they also corrode the heat exchanger’s metal walls over time. When the corroded metal of the exchanger walls heat up they expand, causing cracks to form.


Why Is A Cracked Heat Exchanger Dangerous?


A cracked heat exchanger can allow dangerous exhaust gases to escape into your ductwork. These gases include methane and carbon monoxide, which are completely odorless and capable of causing serious problems for your family’s health.

Make sure your home has a carbon monoxide detector so you can avoid these dangerous effects:

  • Headaches
  • Nausea
  • Dizziness
  • Clumsiness
  • Weakness
  • Suffocation

I was referred to Doug's by a friend, I was greeted on the phone by a very friendly receptionist who took all my info, all that was great. The problem is our technician who came to service my rental property. He was full of attitude, and not professional what so ever according to the tenant. He acted like he was inconvenienced to be making the service call. He called us with the recommendation and pricing, and when we said we would take care of the minor maintenance ourselves, he told our tenant "good luck, because we don't want to spend the money". Hopefully this technician, Samuel, isn't a reflection of Doug's. We all have jobs to do, and if you don't like your job, find a new one! I also left a message for the supervisor to give me a call back yesterday as soon as I found about this information, and have yet to receive a call back.

Just recently moved to Louisiana and I bought a gas stove. Unfortunately, the old owners had an electric one and I don’t know how to change electric outlets or gas line/valve stuff. So, to make a long story short the home is older and has fuses and breakers. So, for my own safety and comfort I contacted them. They were very responsive and were able to get me in the same day! When I googled an electrician Doug’s was the first one to pop up. I’m so glad that him and a team member came to my home and installed two new outlets with correct wiring for the gas stove and switched out the gas valve and knew where the shut off was. So, now I can go to sleep knowing it was done correctly and will not have any issues! So, thank you Doug’s!!!! I will definitely use them again if needed!
