Air Conditioner Sequence of Operation – When a technician is troubleshooting an air conditioner problem it is important that the technician understands the sequence of operation for that equipment. When there is a problem with the equipment, including air conditioners, the technician will know the problem if the equipment or air conditioner does not follow the sequence of operation. Sometimes it is that easy and other times it is not that easy when troubleshooting any type of HVAC equipment. However, it is important to understand the sequence of operation for an air conditioner so the technician can troubleshoot the air conditioner system. (more…)
Home Humidity Control | Why Its Important for Comfort & Health – Humidity is important to our home and health and it is important to maintain the correct humidity in our homes and workplaces for our health. What is humidity? Humidity is simply little water droplets in the air. Cold air is nearly saturated with these little water droplets because the contents of cold air allow the air to hold more water droplets or humidity. As air is heated it expands and holds less humidity.
Home Humidity Control | Why Its Important for Comfort & Health
When you heat the air in your home using a furnace, boiler, or heat pump this air expands and becomes drier. It is air with less humidity relatively speaking before it was heated and compared to the outside air. Air that is 30° F with 80% humidity will only be 15% humidity at 75° F. That is a big difference in humidity levels in the home after the air is heated. Granted, you are not heating air from 30° F to 75° F with your furnace. Depending on the set up of your thermostat and heating system you are most likely heating air that is 68° F to around 70° F to 75° F depending on the thermostat setting. The point is unless you have a source providing humidity to the air stream you are simply reheating dry air from inside the structure. There will be minimal infiltration humidity but the infiltration humidity will never be enough to bring the humidity levels up to healthy levels inside the structure for the inhabitants, plants, and furniture.

Honeywell Chronotherm Plus Thermostat – Trane XL19i Condenser – I have a Honeywell Chronotherm Plus 8624D running a Trane XL19i with a Trane XV90 – all installed new in new construction in 2003. Every winter, during the morning warm-up from 66 to 70, the burners stays on for approximately 1.5 hours at 70, then rises quickly to 73 before finally shutting off. The only way to interrupt the process is to turn the system to OFF at the thermostat. The system is on AUTO with the cooling set at 75 for the winter. I have swapped the thermostats (there are two sets in the house, this is the one in the attic for the second floor) with the same results. I have not swapped the thermostat circuit boards, but I can not see a reason to. The main floor is on the same schedule, but has never done this three degree burst. I have had three different contractors out, with corresponding charges for thermostat troubleshooting with no luck. Have you ever seen this? Any thoughts? Thanks! (more…)

All About Thermostat Wire – Thermostat wire comes in a bundle with the outer jacket of the thermostat wire being either brown or white. The bundle can have anywhere from 2 conductors inside the bundle or outer jacket and all the way up 8 or 10 conductors inside the outer brown or white jacket.
