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…)

Ductwork and High Ceilings - I did not see any reference to my question and would appreciate a response as soon as possible, as due to a medical situation, have to make a decision soon. We own an OLD house with 13′ ceilings in a large part of the home and 11″ ceilings in the LV/DR and BR. We are oscillating on where to place the ducts…Floor or ceiling. It appears to be counterproductive to me to put the ductwork in the ceiling since it will have so far to go.
We are looking for the most cost-effective, not upfront cost but operating cost, solution. In addition, we are considering DF heat pumps. The house will need 2 or 3 to be zoned correctly. Please let me know about the duct placement and thank you for your help? (more…)

Electronic Ignition vs Standing Pilot - Modern gas furnaces use electronic ignition systems to light the burner’s modern furnaces. One can still purchase a gas furnace or water heater with the old standing pilot ignition systems. These systems have been proven reliable and safe over time.
However, why would someone want to purchase a gas furnace or water with a standing pilot ignition system rather than purchase a gas furnace or water heater with an electronic ignition system? Let’s define the two different types of gas furnace or water heater ignition systems. Then we will surmise based on that why someone would purchase a standing pilot gas ignition system over an electronic ignition system.

Gas Furnace Components 3 - Gas furnace ignition controls vary from furnace manufacturer to furnace manufacturer. Some are proprietary and some are from an engineering company that specializes in gas furnace ignition controls. Honeywell being a major manufacturer of controls for HVAC also makes several gas furnace ignition controls.
Gas furnace ignition controls have advanced by leaps and bounds over the last 20 years. The standard was standing pilot ignition. Solid-state ignition controls are safer and more efficient than ignition controls of yesteryear.

Hot Water Unit Heater Protecting Mechanical Room - Unit heaters are used in various places to protect equipment and provide comfort to occupants. This hot water unit heater provides protection for a mechanical room where there is a large air handler and other associated equipment in the mechanical room. This system is controlled by DDC. A thermostat on the wall detects the temperature of the mechanical room. (more…)

Pricing New Air Conditioner - We get emails on a regular basis asking us about prices. Prices for a new air conditioner, heat pump system, boilers, and other types of HVAC systems. This article addresses those questions and why it is nearly impossible to give anyone an estimate.
Estimates for new systems are nearly impossible through email or forum. Someone needs to first look at the house and other factors involved with giving someone a price. (more…)

Gas Furnace with Drain Pipes to Drain the Condensation.
Furnace Water Leak Condensate Problem - Richard, My furnace is leaking water. It is summertime, so I am not using it for heat except for the blower fan which is hooked up to the air conditioner and the heat. I know the pipes from the outside units run into a box on top of the furnace. I think that is a part of the air conditioner. What can I do to fix the problem if you know what the problem is by my explanation here? Dan

Furnace with Hot Surface Ignition
Hot Surface Ignitor - Whenever we talk about electronic ignition systems in gas furnace ignition systems we must first look at the key components which make these systems work and understand how they work. Hot surface ignitor systems work in various ways.
This all depends on what the electronic ignition manufacturer and design engineer determined in the design. Furthermore, some are direct main burner ignition while others light a pilot, and the pilot lights the main burners.

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.
