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 electric HVAC unit uses propane or oil, or natural gas to heat the furnace.

Vents (or registers) are found in the ceiling or on the floor of each room. If you can keep them open to ensure air flows properly throughout your home.

Thermostat

The thermostat is a crucial part of your HVAC system. It regulates the temperature in your home by switching off and on the fan and compressor until they attain a certain temperature, and also switches on the air exchanger to bring fresh air from outside into your home while venting old, indoor air through your ductwork.

The majority of thermostats are digital. However older models are available. Digital thermostats are controlled by the thermosistor. This device has metals which change resistance as temperature changes. The thermistor, connected to a controller, converts the resistance change into temperature. Thermostats are available in a variety of styles that include programmable and smart thermostats that allow you to track your home’s energy usage and make adjustments.

Thermostats are placed on the walls of your house, typically in rooms that are used most often. The location of a thermostat inside your home can affect its accuracy. For instance the thermostat that is located in direct sunlight could read hotter than the actual temperature of the room, causing your system to run excessively or not even run at all. If your thermostat isn’t functioning correctly, you can try setting it again, but if this does not resolve the issue it is recommended to contact an AC technician for help.

If you’re thinking about replacing your thermostat, check out the different options available for you and think about a thermostat that is programmable to help reduce your energy bills. A programmable thermostat will automatically adjust the temperature of your home to meet your schedule instead of having you manually adjust your HVAC system on a regular basis. It is also worth checking to determine if you can locate a better model that can provide you with even greater energy savings, such as an energy-efficient or ENERGY certified thermostat.

Condenser

When your air conditioning isn’t functioning as efficiently as it should one of the most frequent causes can be found in your condenser. The condenser unit is made up of many different parts that all need to be functioning in harmony for the unit to function. The entire system could be affected in the event that any of these parts are damaged or worn out. Problems with the condenser include a malfunctioning condenser control board or leaks of refrigerant.

The compressor moves the refrigerant through the condenser where a fan blows cooled outside air over the coils. This helps the refrigerant to get cool and transform to a liquid state. The low-pressure liquid is chilled and then transferred back into the evaporator to continue the cooling process. The process continues until the desired temperature for your home or business is reached.

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 debris. Leaves, twigs and flowers grass and other debris could be carried into the unit by the condenser fan and result in clogs that can hinder the operation of the cooling system. It is a good idea to keep your trees and shrubs well-trimmed so that they don’t get in the way of the unit. This will help to minimize the chance that branches, berries, or even nuts fall on the system and cause a blockage. Cleaning your condenser of debris can add an additional 1-2 years to the lifespan of your AC system.

Evaporator

The evaporator is the component that moves warm air into your home. It is constructed of a series of tubes that are arranged into panels. The coils are being blown by the air of the blower. This draws heat from indoor air and then transfers it to the refrigerant. The liquid refrigerant becomes an air-borne gas that is circulated through the cooling system to cool the air.

The thermodynamic law states that heat moves from colder objects to warmer ones. If the evaporator operates correctly, this heat energy is transferred from warm air to the colder refrigerant. This causes the refrigerant to vaporize or boil. In this process, heat that is not measured using thermometers, referred to as latent heat is transferred from air to the refrigerant.

These coils have been designed with specialized shapes that enhance heat transfer. They are referred to as fins, and increase the surface area to facilitate the transfer of heat. Some evaporators are built using copper while others use aluminum, with each material offering its own set of advantages.

A evaporator with a buildup of organic growth is prone to problems. This can be a result of mold or mildew. If this is the case, the unpleasant smells caused by the bacteria can be absorbed by the house and could cause discomfort.

To avoid these issues, it is crucial to choose an evaporator that is easily cleaned and maintained. When selecting an evaporator it is essential to take into consideration the environment in which it will be operating. Some evaporators are built to endure harsh environments, whereas others can be used in moderate ones. You should also make sure that the evaporator you choose to purchase is covered by a warranty that will safeguard you and your investment.

Fan

The fan in your HVAC system circulates hot or cold air in your home until you reach the thermostat setting. The fan can be set to auto or constant. We suggest keeping the fan on continuous to maximize efficiency and to save money on electric bills. If your system’s fan keeps running We can replace it with a new ECM blower motor that is up to 70 percent more efficient than the old PSC motors and pays for itself in savings over the life of the unit.

If your fan only runs on high, a short circuit or a malfunctioning relay could be preventing your thermostat from adjusting to the fan.

Filter

The air passes through the filter before it is warmed or cooled and circulated throughout the home. It removes impurities, and also stops dust and pet dander from entering into the system to contaminate internal components. It also shields family members from diseases spread by tiny pathogens that are floating in the air. It also ensures that the system is operating efficiently. A dirty filter makes the system work harder and can cause it overheat or breakdown.

Homeowners should replace their filters regularly. The label will inform them if they should do it every 30 days or every 90 days. If a homeowner isn’t certain which type of filter they require, they should consult an HVAC professional. A professional can assist homeowners select the appropriate filter for their home, in light of factors like climate, how often they use their system and even personal factors for instance, whether there are smokers or allergy sufferers in the house.

The filter is typically located at 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, ceiling, or in the utility closet. It typically has a large metal grate that covers the filter. The filter should be accessible to both homeowners and technicians to make it easy to clean and replace.

Filters are rated according to their MERV rating (Minimum Effectiveness Reporting Value), which shows how well they can capture various sizes of particles. A low-MERV filter is able to remove larger particles such as dust mites and pet dander, but it’s not very effective at catching fine allergens or germs. High-MERV filter can capture various contaminants without affecting the normal flow of air.
