Your HVAC system provides warmth in winter, air conditioning in summer and hot water year-round. Keeping up with these systems requires access to a variety of equipment that is easy to operate and maintain.
Labeling these system components helps facilities personnel easily identify and access them. Ideally, these labels should be easily visible and durable to match the life of the equipment.
Condenser Coil
Purchasing HVAC supplies from the closest location can help reduce travel time and fuel costs for technicians. This can also allow them to get more work done per day.
The condenser coil is part of the outdoor unit of your air conditioner and it works along with the compressor to cool your home. The condenser coil is a network of tubes that holds aluminum or copper fins and it carries heat from the air outside your house.
The condenser coil absorbs the heat from the air as it passes through it, and then it releases the heat to the surrounding environment. The refrigerant vapor then cools down to liquid form and the cooling cycle is repeated. The fan that blows the air across the coil inside your outdoor unit helps to speed up this process so that the hot refrigerant can transfer more heat faster. This helps the cooling system to perform better over long periods of time.
Evaporator Coil
The evaporator coil, found inside the air handler or blower compartment of your HVAC system, absorbs heat from household air and cools it before redistribution. It is made of metals like copper and steel that conduct heat well, and its panels are lined with coiled tubes to maximize heat absorption and cooling effect.
The refrigerant, now in a hot gaseous state, travels to the condenser coil in the outdoor unit, releases its absorbed heat, and condenses back into liquid form. The evaporator coil then resumes its cycle, repeating the process of cooling and heating your home’s air.
The evaporator coil can develop pinhole leaks, resulting in reduced air flow and poor circulation throughout your house. You can reduce the risk by booking an AC service several times a year and keeping the air filter clean. It’s also important to have ductwork cleaned, inspected and repaired, and ensuring that all vents are open. Poor ventilation can lead to mold and mildew growth, which can spread spores throughout your home.
Evaporator Fan
The evaporator fan is a small fan that blows air over the coils to remove the heat and cool the refrigerant. The fan is supposed to run whenever the compressor turns on. However, it can stop working for many different reasons. A simple solution is to clean the fan with hot soapy water. This will remove ice and dirt, which can cause the motor to fail.
Another common issue is a bad evaporator fan blade. This can lead to noise and vibration, but a new carbon fiber blade should solve the problem. It is much stronger and stiffer than plastic or aluminum, which means it can withstand more shock and vibration.
To check the fan, you must first unplug the freezer and shut off power to that room using the breaker or fuse box. Then, you can remove the back freezer panel and access the evaporator fan. You will need to disconnect the wire harness and use a multimeter to check continuity between the control board plug and the fan wire. If the fan fails the continuity test, you may have a broken wire and need to repair it.
Thermostat
The thermostat might seem like a minor component of an HVAC system, but it’s actually a pretty cool piece of technology. It’s also the most common part to be replaced or upgraded in any heating and cooling system.
Some thermostats are equipped with a talking function, which can be helpful for older or disabled homeowners. Others are programmable, which helps homeowners save money by heating and cooling only when they’re home. A time delay function is also available, which prevents the system from automatically starting and stopping, which can wear down the compressor.
For homeowners who are interested in reducing energy costs and increasing comfort, a zoned HVAC system can be installed. While a typical system requires new ductwork, RetroZone offers a simple solution that uses flex-damper air control inserts and an electronic controller. It’s a do-it-yourself installation that can save homeowners up to 30% on their energy costs. It’s also ideal for use in older homes with existing ductwork.Hvac supply near me
