Every New Jersey home needs warmth in winter and air conditioning in summer. Keeping these homes in good condition requires high-quality HVAC and refrigeration equipment.
Labeling HVAC system components helps facilities personnel understand how to operate and maintain the systems. It also makes troubleshooting issues easier. Purchasing HVAC supplies at the nearest supply house can reduce travel time and labor costs.
Evaporator Coil
The evaporator coil is the component of your HVAC system that absorbs heat and moisture from your home’s air. It works alongside the condenser coil to cool your home.
The coil has thousands of coiled tubes made of copper and aluminum that are good conductors of heat. As the blower fan draws warm air from your house, it passes over the coil’s cold surface and transfers its heat to the refrigerant inside. The heat causes the refrigerant to evaporate, changing it from a low-temperature liquid into a cooling vapor.
The evaporator coil circulates the vapor throughout your system’s ductwork, cooling your home or workplace. It’s crucial that it be clean to ensure maximum heat absorption and efficiency. A dirty evaporator coil will use more energy to do its job, costing you more in energy bills and reducing your comfort. A professional HVAC technician can assess the evaporator coil and recommend the right maintenance plan for it.
Condenser Coil
The condenser coil is found in the large, square outdoor unit of your air conditioning system. Like the evaporator coil, it works in tandem with the compressor to cool your home. When refrigerant exits the evaporator coil in gaseous form, it travels to the outdoor unit, where the compressor compresses it into liquid form.
Once inside the compressor, it flows into the condenser coil, where a high-powered fan blows air over it. This allows the hot, gaseous refrigerant to reject its accumulated heat energy into outdoor air, cooling the air.
Because the condenser coil is outside, it’s exposed to harsh weather conditions and debris. As a result, it is more likely to suffer from dirty, dusty, or clogged coils that reduce its efficiency. Proper maintenance and regular inspections by a professional HVAC technician can help prevent these problems.
Evaporator Fan
The evaporator coils absorb heat from the freezer compartment and the fan motor circulates the cool air produced by the coils to all areas of the freezer. If the evaporator fan isn’t running or is making high pitched noise, a simple continuity check with a multimeter will tell you whether the problem is with the electronic control board, the evaporator fan motor, or the wire harness connecting them. Before attempting any repairs, shut off power to the freezer by using the breaker or fuse box for the house. Then, remove the back freezer panel to access the evaporator fan. There are usually two wires that need to be checked for continuity; the coil should register zero ohms and the wire harness plug should also register no ohms.
If there is ice build-up on the blades, melting it with penetrating oil will allow the fan to run freely. Physical obstructions or loose blades can also cause problems; they should be straightened as soon as possible to prevent them from bending and jamming.
Ductwork
Ductwork is used in heating, ventilation and air conditioning (HVAC) to supply and extract air. It consists of a network of flexible or rigid tubes. It runs through voids above suspended ceilings and connects to all areas of a building. These networks may contain supply and return ducts, diffuser grilles, and a range of accessories such as take-offs, volume control dampers, smoke/fire dampers, turnouts, and access doors.
The most common type of duct is rigid sheet metal, which has a durable surface that is easy to clean and resists mold growth. Another popular type is fiberglass ducts, which provide built-in insulation and reduce sound transmission.
Leaking ducts can increase energy costs and cause rooms to have different temperatures. They can also be a source of dust, which is irritating to sensitive people. If you notice a musty smell or dust by your vents, these are signs that your HVAC system is leaking. An expert can diagnose the problem and determine if the ducts need to be replaced.Hvac supply near me
