Imagine my surprise when I came home from work one freezing cold evening and found water flooding my basement. I ran to turn off the water and then I called the plumber. Even though it was late in the evening, the plumber immediately came to my house and fixed the busted water line. The plumber told me that I could have prevented my water line from freezing and busting if I had winterized the pipes. After researching various methods, I insulated the pipes so they won't freeze again. My name is Joel Hampton and this blog is about the different ways to winterize your plumbing pipes to keep them from freezing. Coming home to a basement filled with water is a nightmare and I hope that after reading the information in my blog, it won't happen to you.
One of the newer HVAC options available is the high-efficiency condensing furnace. These options are able to convert almost all of the fuel used by the furnace into heat, while conventional furnaces, in contrast, are only able to convert 90% or less. The heat is extracted efficiently enough that the furnace is usually warm to the touch rather than being hot:
1. Ventilation Problems
Even though there are many benefits to high-efficiency condensing furnace, they can still have problems just like with almost every other appliance. One of the common problems faced by condensing furnaces affects ventilation.
High-efficiency furnaces exhaust gas and bring outdoor air inside. Sometimes, the pipes are not connected correctly and this can cause problems for your furnace, including causing the control board to go into lockout. This occurs during the winter due to snow building up on the vent pipe. Since exhaust cannot flow properly as a result, the furnace will usually shut down.
There are a few common problems to look out for when diagnosing exhaust problems:
2. Ignition Problems
Like with conventional furnaces, condensing furnaces can have problems with ignition. However, in addition to the problems commonly faced by conventional furnaces regarding the ignition, condensing furnaces can suffer from a blocked condensate drain, an excessive buildup of condensate in the drain pan and a flue vent that is partially clogged. Fortunately, most of these problems can be corrected by cleaning the parts of the furnace affected.
3. Moisture Problems
You may begin to notice moisture problems in your home that did not exist before you installed a high-efficiency furnace. This can include excessive condensation in the attic and near the windows. There are several ways to solve this, such as running a dehumidifier. However, these options are not very green. The best option, instead, is to install a heat recovery ventilator.
4. Pressure Switch Problems
You may have a bad furnace pressure switch. This device is designed to protect you by detecting negative pressure caused by a draft inducer and shutting down the ignition. A bad pressure switch usually results from the pressure switch not receiving enough electricity. You should have this HVAC repair, but there are a few things you can do in the meantime.
First, you can flick the pressure switch with your finger to get it to function. You can also disconnect the tube that attaches to the pressure switch and blow on it until you hear the diaphragm move.
