Honeywell Gas Furnace Ignition Control Modules | HVAC Heating. There are many different types of gas furnace ignition control modules that control a gas furnace or gas boiler. These solid-state control modules can easily be retrofitted to replace other control modules. In some cases, printed circuit boards in case of failure. The key is to replace the failed module or furnace control board with a new control module that will offer the correct sequence of operation.
A gas furnace ignition control module that matches the same ignition components. One of the largest manufacturers of gas furnace and gas boiler ignition controls is Honeywell. The gas ignition control modules offered by Honeywell include the following modules:

What you will learn from HVAC Refrigerant Leaks:
- This article will instruct you on the top reasons and places in the HVAC system for refrigerant leaks. Some people say Freon® leaks.
- What happens when an air conditioner or heat pump has a low refrigerant charge as a result of a refrigerant leak. How a refrigerant leak affects your AC system.
- What you will see or experience with your heating and air conditioning HVAC system if you have a refrigerant leak.
- Why HVAC Contractors do not provide warranties for refrigerant leaks for heating and air systems.
- Making the decision to repair the leak or replace the system.
- Basic air conditioning repair and heat pump repair. How repairing a leak will take your system from low efficiency to high efficiency. This can also apply to a mini-split or ductless system.
- Differences between new refrigerants and old refrigerants.
- Plenty of in-depth related links that will allow you to understand the subject better.

Heat Exchanger & Domestic Hot Water Storage Tank
Heat Exchanger & Domestic Hot Water Storage Tank - In the front is a commercial heat exchanger. Behind the commercial heat exchanger is a domestic hot water storage tank.
The entire system is monitored by direct digital controllers to control the water temperature, the boilers, the valve actuators, and the heat exchangers. It is important to monitor the temperature of any domestic water system. Temperatures above 130° F. should be avoided as they will scald people. This can result in legal issues so it is important this is controlled accurately. Direct Digital Control can offers alarms for this issue in case something goes wrong or something fails.

Blank Display on Thermostat Problem - Screen Disappeared - The thermostat display is our interface with our HVAC equipment. The display lets us know what the temperature is in the house. The display tells us what the desired settings are including letting us know the setpoint setting the temperature.
Some displays give us time, and the newer modern displays show us family photos like a screensaver on our computer. But what happens when the display is not there, or there is a blank thermostat display or no display on the thermostat?
Is it a bad thermostat or something else that caused the display to disappear? What do you do when the thermostat screen is not working? (more…)

Boiler Supply and Return Piping - Any heating pipe system will experience a heat loss in the pipe even when the pipe is insulated. The loss is far greater when the pipe is uninsulated. Good boiler piping insulation will reduce the heat loss experienced in the pipe run throughout the loop especially where the pipe runs in unconditioned or unheated spaces where heating is not necessary.
Boiler Supply and Return Piping
Good Supply and Return Insulated Pipe will increase the efficiency of the boiler and reduce overall the heat loss of the entire system as a whole throughout the heating season. Insulate exposed piping wherever you find it and replace old insulation that is falling off. Be careful to identify the correct insulation and never ever disturb asbestos insulation. Asbestos is dangerous especially if you breathe in the particles from it. A professional asbestos remediation company must be hired to remove it safely.
