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 of an all-electric HVAC unit uses propane or oil, or natural gas to heat the furnace.
Vents (or registers) are located in the ceiling or on the floor of every room. If you can you can keep them open to ensure air is flowing properly throughout your home.
Thermostat
The thermostat is a crucial component of your HVAC system. It regulates the temperature of your home by turning off and on the fan and compressor to attain a pre-set temperature. It also turns on the exchanger to draw fresh air from outside your home and then vent stale air through your ductwork.
The majority of thermostats are digital. However, older models do exist. Digital thermostats are controlled by the thermosistor. This device has metals that change resistance when the temperature changes. The thermistor is connected to an microcontroller that converts changing resistance into the temperature reading. There are a variety of thermostats including smart and programable thermostats. They allow you to control and adjust your home’s power consumption.
Thermostats are placed on the walls of your house, typically in rooms where they are used most often. The location of a thermostat in your home could affect its accuracy. A thermostat placed in direct sunlight, for example it could display more heat than the actual room temperature. This could cause your system to operate more or less. If your thermostat isn’t functioning correctly, you can try setting it again but if that does not resolve the issue then you should contact an AC technician for assistance.
Consider a programmable thermostat when you are replacing your existing thermostat. You’ll save money on energy bills. A thermostat that can be programmed will automatically adjust the temperature of your home according to your schedule, instead of requiring you to manually manipulate your HVAC system each day. It’s also worth checking to determine if you can locate an improved model that could provide you with even greater energy savings, like an energy-efficient or ENERGY STAR-certified thermostat.
Condenser
If your air conditioner isn’t working as efficiently as it is supposed to one of the most common causes is your condenser. The condenser is made up of a number of parts that have to cooperate to make the unit function. If any of these parts are damaged or worn out, the whole system may be affected. Condenser issues can include a damaged control board for the condenser or leaks of refrigerant.
The compressor moves the refrigerant through 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. This liquid at low pressure is cooled and returned to the evaporator to continue cooling. The cycle is repeated in order to reach the temperature you desire for your office or home.
The most important thing you can do to ensure that your condenser running properly is to make sure that the area around it stays free of any debris. Leaves, twigs, flowers grass and other debris could be carried into the unit by the condenser’s fan and result in clogs that can hinder the operation of the cooling system. It’s also a good idea to keep trees and shrubs trimmed so they don’t encroach onto the unit. This reduces the likelihood that nuts, berries or branches will enter the system and clog it. The condenser that is free of debris can add an additional 1-2 years to the lifespan of your AC system.
Evaporator
The evaporator circulates warm air inside your home. It is made of a string of tubing which is u-shaped, and set into panels. The coils are blown by air from the blower. This draws heat from the indoor air and then transfers it to the refrigerant. The refrigerant’s liquid is converted into a gas, then circulated throughout the cooling system to cool your indoor air.
The thermodynamics law states that heat flows from colder objects to warmer ones. When the evaporator operates correctly, the energy of heat is transferred from the warm refrigerant to the cold air. This causes the refrigerant to vaporize or boil. During this process the latent heat (which cannot be measured using a thermometer) is transferred from the air to the refrigerant.
The coils are made with special structures that enhance the transfer of heat. Fins are used to increase the surface area of the coils. Copper and aluminum are both used to make evaporators, each having their own advantages.
One of the most common problems with evaporators is the accumulation of organic growth. This is usually caused by mildew or mold. If this is the case, the foul smells that the bacteria produce will be circulated throughout the house and could cause discomfort.
It is essential to choose an evaporator that is easily cleaned and maintained. When selecting an evaporator it is crucial to think about the working environment. Some evaporators are built to stand up to harsh conditions, while others can be used in moderate ones. You should also make sure that the evaporator you choose to purchase is protected by a warranty that will protect you and your investment.
Fan
Your HVAC system’s blower fan works to circulate the hot or cold air throughout your home until the temperature you have set is attained. The fan can be turned on automatic or constant. We suggest keeping the fan on at all times for maximum efficiency and to save money on electricity costs. We can replace the fan motor when it is running continuously. The new ECM motor is 70 percent more efficient than the old PSC motors. It is able to pay for itself over the lifetime of the unit.
If your fan is only operating at the highest setting, a malfunctioning relay switch or short circuit could be blocking the settings you set on the thermostat from reaching your fan.
Filter
The filter is used to circulate air in the home before it is heated or cool. It eliminates impurities and prevents dust and pet dander from entering the system and contaminating internal components. It also shields family members from diseases spread by tiny pathogens that float in the air. It also ensures that the system is functioning properly. A dirty filter can cause the system to work harder, which could cause it to overheat and eventually break down.
homeowners should change their filters on a regular basis. The label will inform the homeowner if they should replace it every 30 days or every 90 days. A homeowner should consult a HVAC professional if they are unsure of the type of filter they require. A professional can assist them in selecting the most appropriate filter for their home based on the climate and the amount of time they use their system, and other personal factors like the presence of allergy sufferers or smokers within the home.
The filter is usually found in the return air duct or in some cases, the blower compartment of the furnace. The return air duct could be found on the wall, floor or ceiling, or in a in the utility closet. It typically has a large metal grate that covers the filter. The filter should be accessible to homeowners and technicians to make it easy to clean and replace.
Filters are rated by the MERV (Minimum Efficiency Reporting Value) rating, which reveals how effective they are at collecting different sizes of particles. A filter with a low MERV rating is able to remove larger particles such as dust mites and pet dander however it’s not as effective in capturing fine allergens or germs. High-MERV filter can capture many kinds of contaminants while not affecting the flow of air.
