It includes a thermostat, a condenser, and an air handler with a heat source. The heat source for a basic AC system can include heat strips for electric heat or even a hot water coil inside the air handler that is fed from a water heater. All the relays in the system have volt coils. Circuit boards or printed circuit boards found in modern systems utilize volt control which originates from the control transformer. Typical systems that do not use volt control are window unit air conditioners, ductless mini split systems, and baseboard electric heating systems. If you are unsure about the control voltage of your system consult an HVAC professional as some appliances use high voltage and this can be dangerous. Standard 18 gauge thermostat wire is used for all control wiring. The W terminal is for heating including the heating for gas furnaces, electric furnaces, boiler systems and the back-up heat for heat pumps. The G terminal is for the blower fan located in the air handler.

This hole allows for a thorough system inspection and provides a hook-up point for the high velocity HEPA vacuum. One out of six people who suffer from allergies do so because of the direct relationship to fungi and bacteria in air duct systems. An air hose is snaked through each branch duct and high pressure air blasts the debris from the inside surfaces of the duct. The HEPA vacuum pulls the dislodged contaminants into its filtration system.

Drilled holes are plugged and all captured debris is removed from the home.

Ancient hygrometers[ edit ] Prototype hygrometers were devised and developed during the Western Han dynasty in Ancient China to study weather. The differences in weight were used to tally the humidity level. Other techniques were applied using mass to measure humidity, such as when the air was dry, the bar of charcoal would be light, while when the air was humid, the bar of charcoal would be heavy.

By hanging a lump of earth and a bar of charcoal on the two ends of a staff separately and adding a fixed lifting string on the middle point to make the staff horizontal in dry air, an ancient hygrometer was made. In these devices, water vapour is absorbed by a salt-impregnated paper strip attached to a metal coil, causing the coil to change shape. These changes analogous to those in a bimetallic thermometer cause an indication on a dial.

On this page we have listed some popular questions with answers that our customer’s have asked us in their emails. I hope this will help answer some of your questions about heating and air conditioning.

Homes like this are increasingly common. Dozens of builders are telling us this is happening. Or you can try using equipment designed for sailboats. The PassivhausA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. To meet the standard, a home must have an infiltration rate no greater than 0. The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.

The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. But you might only need 25, Btuh for space heat. If you install a tankless heater with a capacity of 90, to , Btuh, which is typical for Americans in a northern climate, you end up with an appliance that is four times the capacity of your space heating needs.

To find the right equipment, Straube suggests that you consider a series of questions:

Im a EPA certified HVAC-Technician,i use guages for air conditioning and refrigeraters,but the hoses couldnt fit on a automobile air conditioner,with these,you can hook up your HVAC guages to these and the quick coupler adapter hooks easly to the low and high side ports on a car to check pressure readings on guages and charge refrigerant to low side adapters work perfect,very good.

These filteres come in standard dimensions with a depth of 6″ and 12″. Three styles are available: They may also be utilized where extreme velocity or turbulence have rendered other products to be ineffective. They feature the same rugged construction as the Gas Turbine PrecisionCell. The HT version is manufactured of specially selected components to meet high temperature requirements.

They are ideal for paint drying ovens or any application requiring high efficiency filtration at high temperatures. They are designed for use in most commercial and industrial HVAC systems where medium to high efficiency filtration is required. Two styles are available:
