Why Your HVAC System Isn’t Working As Well As It Should
Your HVAC system sends temperature-regulated air through ductwork into different areas of your home. The blower in an all-electric HVAC unit uses propane or oil, or natural gas to heat the furnace.
Each room has vents (or registers). They are located on the ceiling or walls, or floors. If possible keep them open to ensure that air circulation is properly distributed throughout your home.
Thermostat
A thermostat is among the most important parts of your HVAC system. It regulates the temperature of your home by turning off and on the compressor and fan to attain a certain temperature, and also activates the air exchanger to help draw fresh air from outside into your home while exchanging stale indoor air through your ductwork.
The majority of thermostats are digital although older models do exist. Digital thermostats are controlled by the thermosistor. The device is made of metals that alter resistance as temperature changes. The thermistor, connected to a controller, converts the resistance change into temperature. There are many types of thermostats, including smart and programable thermostats. They let you control and adjust your home’s energy consumption.
Thermostats can be positioned on the walls of your home’s interior, usually in the rooms most frequently used. The location of your thermostat can affect its accuracy. A thermostat that is placed in direct sunlight, for example could show an upper temperature than the actual temperature of the room. This can cause your system to run more or less. If your thermostat isn’t operating properly, you can try resetting it however if this doesn’t fix the problem it is recommended to contact an AC technician for assistance.
You should consider a programmable thermostat if you are replacing your current thermostat. You will save money on energy bills. A thermostat that is programmable will automatically adjust the temperature of your home to your preferences, rather than needing you to manually operate your HVAC system each day. You should also check to determine if there’s an efficient model, for instance one that is ENERGY STAR certified or energy-efficient.
Condenser
When your air conditioning isn’t performing as well as it ought to one of the most common causes is your condenser. The condenser unit is made up of many different components that must be functioning in harmony for the unit to work. The entire system could be affected when any of these components are damaged or worn out. Problems with the condenser include a malfunctioning control board for the condenser or leaks of refrigerant.
The refrigerant gas from the compressor is pumped into the condenser, where a fan blows cool outside air over the coils. This allows the refrigerant gas to cool, and return to a liquid form. The liquid that is cooled moves back into the evaporator where it continues the cooling process. The cycle is repeated until it reaches the desired temperature for your office or home.
The most important thing you can do to ensure that your condenser working properly is to make sure that the area around it stays free of any debris. The condenser’s fan can pull leaves, twigs and other debris into the unit, causing clogs and hindering the cooling system from working properly. It’s also a good idea to keep your trees and shrubs cut back so that they don’t touch the unit. This will reduce the chance that berries, nuts or branches fall into the system and clog it. Keep your condenser in good condition to prolong the life of your AC by a minimum of 1-2 years.
Evaporator
The evaporator is a component that allows warm air to enter your home. It is constructed of a series of tubes, which are then set into panels. The air from the blower fan is blown over these coils. This draws heat from indoor air and transfers it to the refrigerant. The refrigerant liquid is transformed into a gas, then circulated throughout the cooling system to cool the indoor air.
The law of thermodynamics states that heat travels from colder objects to warmer ones. When the evaporator functions properly, the energy is transferred from the refrigerant that is warm to the cool air. This causes the refrigerant to boil or evaporate. During this process, the heat that is not measured with thermometers, also known as latent heat, is transferred from the air to the refrigerant.
The coils are made with specialized structures that improve the transfer of heat. These are known as fins and increase the surface area to help in the transfer of heat. Certain evaporators are constructed with copper while others use aluminum, with each material having its own set of advantages.
An evaporator that is afflicted with an accumulation of organic growth is prone to issues. This could be caused by mildew or even mold. If this happens, the bacterium will produce a smell that spreads throughout the house. This may cause discomfort.
To avoid these issues, it’s crucial to choose an evaporator which can be easily cleaned and maintained. When selecting an evaporator it is important to also consider the working environment. Some evaporators can withstand harsh environments, while others can be used in moderate environments. Lastly, you will want to make sure your evaporator has a solid guarantee that will protect your investment.
Fan
Your HVAC system’s blower motor works to circulate cool or hot air through your home until the thermostat you have set is reached. The fan can be set to auto or constant. We recommend that you keep the fan running continuously to maximize efficiency and reduce your electric bills. We could replace the fan motor when it is running continuously. The new ECM motor is 70 percent more energy efficient than the old PSC motors. It is able to pay for itself over the life of the unit.
If your fan only operates on high, an unbalanced circuit or a broken relay could be preventing your thermostat from adjusting to your fan.
Filter
Air passes through the filter, before being warmed or cooled and circulated throughout the home. It removes impurities and keeps dust and pet dander from entering the system and contaminating internal components. It also shields family members from diseases spread by tiny pathogens floating in the air. It also ensures that the system is functioning properly. A dirty filter makes the system work harder and could cause it overheat or break down.
homeowners should change their filters on a regular basis. The label will inform them if they should do it every 30 days or every 90 days. If a homeowner isn’t sure what kind of filter they need, they should consult an HVAC professional. A professional can assist them in selecting the best filter for their home based on climate and the amount of time they use their system, and other personal factors such as the presence of allergy sufferers or smokers in the house.
The filter is usually located in the return air duct or, in certain cases, in the blower compartment of the furnace. The return air duct may be found on the wall, floor or ceiling, or in a in the utility closet. It often contains a large metal grate that covers the filter. The filter is accessible to homeowners and service technicians to facilitate cleaning and replacement.
Filters are evaluated based on the MERV (Minimum Efficiency Reporting Value) rating, which indicates how efficient they are at collecting different sizes of particles. A filter with a low MERV will be able to filter larger particles such as dust mites or pet dander but not fine allergens and germs. High-MERV filters are able to capture a variety of contaminants without affecting the flow of air.
