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 runs on propane or oil, or natural gas as fuel to heat the furnace.
Every room has vents (or registers). They are situated on the ceiling, walls or floors. If you can keep them open to ensure air is flowing properly throughout your home.
Thermostat
The thermostat is an essential element of your HVAC system. It regulates your home’s temperature by turning on and off the fan and compressor until they reach a set temperature, and also activates the air exchanger in order to bring fresh air from outside into your home while venting old, indoor air out through your ductwork.
The majority of thermostats are digital. However older models are available. Digital thermostats are controlled by the thermistor. The device contains metals that change resistance as temperatures change. The thermistor is connected to a controller converts the resistance change into a temperature. There are many types of thermostats, including smart and programable thermostats. They let you monitor and adjust your home’s energy consumption.
Thermostats are installed on the walls of your home, usually in rooms where they are used most often. The place of your thermostat will affect its accuracy. A thermostat that is placed in direct sunlight, for example could show a higher temperature than the actual room temperature. This can cause your system to run more or less. If your thermostat isn’t operating properly, you can try reset it, but if this does not resolve the issue, you should call an AC technician for assistance.
You should consider a programmable thermostat if you are replacing your existing thermostat. You will save money on energy bills. A thermostat that can be programmed will automatically adjust the temperature of your home according to your preferences, rather than needing you to manually operate your HVAC system each day. It’s also worth a look to determine if you can locate an alternative that will give you more energy savings, like an energy-efficient or ENERGY A STAR-certified thermostat.
Condenser
Condensers are usually the cause when your air conditioner isn’t performing as well as it should. The condenser consists of several components that be in sync to ensure that the unit functions. If any of these parts become damaged or wear out, then the entire system may be affected. The most common problems found in the condenser are damaged control board or leaks of refrigerant.
The refrigerant gas that is produced by the compressor is pushed into the condenser where the fan blows cool air from outside over the coils. This allows the refrigerant gas to cool, and return to a liquid state. This low-pressure liquid is then chilled and then transferred back into the evaporator to continue cooling. The process repeats to achieve the temperature you desire for your office or home.
To ensure that your condenser is operating properly, you should ensure that the area around it is free of debris. The condenser’s fans can pull leaves, twigs and other debris into the unit, causing blockages and hindering the cooling system from functioning effectively. It’s also a good idea to keep the trees and shrubs cut back so that they don’t get in the way of the unit. This will help to minimize the risk that branches, berries, or nuts will fall and clog the system. The condenser that is free of debris can add two or three years to the lifespan of your AC system.
Evaporator
The evaporator moves warm air in your home. It is made of a series of u-shaped tubes that are arranged 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 liquid refrigerant is converted into a gas and circulated throughout the cooling system in order to cool your indoor air.
The thermodynamics law states that heat is transferred from hotter to colder objects. When the evaporator is operating correctly, the energy passes from the warm air to the refrigerant that is colder. This causes the refrigerant to boil or evaporate into gas. In this process, the latent heat (which is not measurable with thermometers) is transferred from air to refrigerant.
These coils have been designed with specialized shapes that enhance heat transfer. Fins are used to increase the surface area of coils. Copper and aluminum are both used to build some evaporators, each with distinct advantages.
One of the most common problems with evaporators is an accumulation of organic growth. This could be caused by mildew or mold. If this happens, the bacterium will produce a smell that can spread throughout the home. This may cause discomfort.
It is crucial to choose an evaporator that can be easily cleaned and maintained. When selecting an evaporator it is important to also consider the working environment. Certain models are designed to withstand harsh conditions, while others can be used in moderate environments. Lastly, you will want to ensure that your evaporator has a solid warranty that will safeguard your investment.
Fan
The blower fan of your HVAC system circulates hot or cold air throughout your home until you reach the temperature setting. The fan can be set to automatic or constant. We recommend keeping the fan running constant for maximum efficiency and to cut down on electricity costs. If your system’s fan keeps running, we can replace it with an ECM blower motor that is up to 70 percent more efficient than the old PSC motors and will pay for itself in savings over the duration of the unit.
If your fan is only operating at the high setting, a broken relay switch or short circuit may be hindering the settings you input on the thermostat from reaching your fan.
Filter
The air passes through the filter, before being warmed or cooled, and then circulated throughout the home. It eliminates impurities and prevents dust and pet dander from entering the system and contaminating the internal components. It shields the family from illnesses spread by airborne pathogens. It also ensures that the system is functioning properly. A dirty filter causes the system to work harder, which can cause it to overheat and break down.
homeowners should replace their filters on a regular basis. The label will tell them whether they should do it every 30 days or every 90 days. A homeowner should consult a HVAC professional in case they are not sure of the type of filter they need. A professional can help homeowners select the appropriate filter for their home depending on factors such as temperature, how often they use their system and even personal preferences, such as whether there are allergy or smokers sufferers in the house.
The filter is located in the return air duct, or in some cases the blower compartment of the furnace. The return air duct can be found on the floor, wall or ceiling, or even in the utility closet, and it typically has a large metal grate that covers the filter. The filter should be easily accessible for homeowners and service technicians to aid in cleaning and replacement.
Filters are rated based on their MERV rating (Minimum Effectiveness Reporting Value), which shows how well they capture various sizes of particles. A filter with a low MERV rating can be used to catch larger contaminants like pet dander and dust mites, but it’s not very efficient in catching small allergens or germs. High-MERV filter can capture various contaminants, but it doesn’t affect the normal flow of air.
