Home Humidity Problems - HIGH HUMIDITY 60 % +. Within the last month, I moved into a new house. It has drywall and not plaster walls. The furnace and hot water tank were installed a week or so before we moved into the house. Last week we determined that there is a humidity issue when the windows were sweating. We are trying to determine the source of the humidity. The contractor feels it may be the high-efficiency furnace. I have a Lennox g61mp. The combustion air is pulled from within the unfinished basement. Should the air be pulled from the outside? The gases are vented via PVC pipe which slopes back to the furnace. (more…)

High-Efficiency Electronic Ignition Gas Furnaces are here. They are the next step up from the standing pilot gas furnace. These gas furnaces are more efficient than the standing pilot furnaces but more complex in design. There are three types of electronic ignition gas furnaces: the intermittent spark pilot, the intermittent hot surface ignition pilot (Honeywell Smartvalve and ignition assembly), and the hot surface ignition furnaces.
While the three are different they all offer higher efficiencies and are both controlled by solid-state circuit boards. Many of these furnaces also have higher efficient heat exchangers.

Water Dripping from Air Conditioner - We have 2 air conditioning units in our house and 2 pipes protrude from the roof. One of the pipes is dripping water. We were told to look for a blockage and to empty the pans. I don’t see where to check for a blockage. Any suggestions?
The air conditioning units we have: Bryant models 373LAV, 376CAV Downflow/Horizontal and 383KAV, 395CAV Upflow Gas Furnace. (more…)

Natural Gas Regulators
Natural Gas Properties and Furnace Heating Efficiency - Natural Gas is a popular fuel used for heating systems in America and other countries. If we look at the properties of natural gas and the heating efficiency of natural gas furnaces we will see that natural gas furnaces lose efficiency because of what is contained in natural gas as it is delivered to your home for consumption by your natural gas furnace.
Natural gas in its raw form coming straight from the ground needs to be refined to remove impurities that should not be contained in natural gas. As you read below you will see that in the refining process moisture is removed from the natural gas however during the refining process some of the moisture in the natural gas remains and therefore this affects the efficiency of your natural gas furnace.
