What Is a Booster for a House Air Conditioner?

The booster is an important component, because your air conditioner will not run without it. Simply put, the booster is a capacitor; you might hear it called a hard start capacitor. It gives the compressor motor a boost when its trying to start. In some residential air conditioners, the booster is built into the compressor startup circuitry. Homeowners who have air conditioners without boosters often add one later to assist an aging compressor.

How Does an Old Hydronic Boiler System Work?

Hydronic boiler systems refer to heating systems that provide heat by moving heated water through a closed-loop piping system. Closed looped means sealed and not open to the atmosphere. In a perfect system you would not see any water loss. The heat generated in the boiler is ultimately transferred by convection and radiation to your home. The system consists of four major components: the boiler, associated piping, the pump and radiators.

How to Cut and Join Duct Board

Duct board is a fiberglass insulation board covered in a plastic or metallic coating. It's rigid like sheet metal ductwork, but has insulating qualities because of the fiberglass or other insulating materials used in its construction. It can be formed into rectangular ducts and is cut with a utility knife or special duct-board cutting tools, such as a kerfing or a shiplap tool.

High-Efficiency Furnace Won't Start in Extreme Cold Temps

High-efficiency furnaces, also known as condensing furnaces, recirculate hot combustion gases to cause them to condense before venting. Surplus heat released naturally in the condensation process is recovered by a secondary heat exchanger, boosting energy efficiency in these models to an AFUE (Annual Fuel Utilization Efficiency) rating of over 90 percent. The technology generates up to a gallon of condensate a day as a byproduct. In residential applications, this liquid may be conveyed out of the house through a PVC discharge pipe that terminates on the outside of an exterior wall. If the condensate drain outlet is blocked, your high-efficiency

Does a Return on a Furnace & Central Air Make the House Cooler?

The central cooling and heating system in your home is a closed loop designed to recirculate, not ventilate. While the ductwork that conveys cooled and heated air throughout your home may appear to be a single layout, its actually two separate systems. Supply ducts deliver cool air from the air conditioner or hot air from the furnace to the living spaces. The returns make up the other other half of the system. Connected to dedicated vents in each room or a central return grille in a common area such as a hallway, returns perform the vital function of circulating air
