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 runs on propane or oil as well as natural gas to heat the furnace.

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

Thermostat

A thermostat is one of the most vital components of your HVAC system. It regulates the temperature in your home by switching off and on the compressor and fan to achieve a specific temperature. It also activates the air exchanger to help pull fresh, outside air into your home while venting stale, indoor air through your ductwork.

The majority of thermostats are digital. However there are older models. Digital thermostats are controlled by a thermistor. The device is made of metals that change resistance as temperature changes. The thermistor is connected to an microcontroller that converts changing resistance into the temperature reading. There are many types of thermostats, including smart and programable thermostats. These allow you to control and adjust your home’s energy consumption.

Thermostats can be placed on the walls of your home’s interior, usually in the rooms most frequently used. The position of your thermostat could affect its accuracy. For instance the thermostat that is located in direct sunlight could read hotter than the actual temperature of the room and cause your system to overrun or not run at all. If your thermostat isn’t working correctly, you can try reset it, but if this does not solve the issue then you should contact an AC technician for assistance.

If you’re thinking about changing your thermostat, you should check out the different options available for you, and consider the possibility of a programmable thermostat to save money on your energy costs. A programmable model will automatically adjust the temperature of your home according to your schedule rather than needing you to manually operate your HVAC system each day. It’s also worth a look to see if you can find an improved model that could offer you even more savings on energy, like an energy-efficient or ENERGY certified thermostat.

Condenser

Condensers are usually the cause when your air conditioner isn’t working in the way it should. The condenser is comprised of a number of parts that have to work together to ensure that the unit functions. The entire system can be affected when any of these components are damaged or worn out. Condenser issues can include a damaged control board for the condenser or leaks of refrigerant.

The refrigerant gas produced by the compressor is pushed into the condenser where fans blow cool outside air over the coils. This helps the refrigerant cool down and convert back to a liquid state. This low-pressure liquid is then removed and cooled before being transferred back into the evaporator to continue the cooling process. The process repeats in order to reach the desired temperature for your office or home.

To ensure that your condenser is operating correctly, you must ensure that the area surrounding it is free of debris. The condenser’s fan could draw leaves, twigs, and other debris into the unit, creating clogs and hindering the cooling system from working properly. It’s also a good idea to keep trees and shrubs trimmed so they don’t touch the unit. This will help to minimize the possibility that berries, branches, or nuts could fall and block the system. Keeping your condenser free from debris can add 1-2 additional years to the life of your AC system.

Evaporator

The evaporator is the thing that is used to move warm air around your home. It is made of a series of tubing which is u-shaped and placed into panels. The air from the blower fan is blown through these coils. This transfers heat from the indoor air to the refrigerant. The refrigerant’s liquid becomes a gas that circulates through the cooling system to cool the air.

The thermodynamic law states that heat moves from colder to warmer objects. If the evaporator is operating correctly, this heat energy is transferred from warm air to the refrigerant that is colder. 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.

These coils are constructed with specific structures that aid in the transfer of heat. Fins are used to increase the surface area of the coils. Some evaporators are built using copper while others make use of aluminum, each offering its own set of advantages.

A evaporator with an accumulation of organic growth can be prone to issues. This could be the result of mildew or mold. If this is the case, the foul odors produced by the bacteria can be absorbed by the home and can cause discomfort.

It is important to select an evaporator which can be easily cleaned and maintained. When selecting an evaporator it is essential to consider the working environment. Some are designed to withstand harsh conditions while others are suited to moderate environments. It is also important to ensure that your evaporator is protected by a warranty that will safeguard you and your investment.

Fan

Your HVAC system’s blower fan works to circulate the cool or hot air through your home until the temperature you have set is attained. The fan can either be set to auto or constant. We suggest keeping the fan on continuous to maximize efficiency and to cut down on electric bills. If your system’s fan is constantly running we can replace it with a brand new ECM blower motor which is up to 70% more efficient than old PSC motors and will pay for itself in savings over the life of the unit.

If your fan is only operating at the high setting, a broken relay switch or short circuit could be hindering the settings you input on the thermostat from reaching your fan.

Filter

Air flows through the filter before being heated or cooled before being circulated around the house. It removes impurities and also stops dust and pet dander getting into the system and contaminating internal components. It also protects family members from diseases spread by tiny pathogens floating 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 ultimately break down.

homeowners should replace their filters regularly. 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 in case they are not sure about the kind of filter they require. A professional can assist them in choosing the best filter for their home based on the climate and how often they use their system, and personal factors such as the presence of allergy sufferers or smokers within the home.

The filter is usually located at the return air duct or, in certain cases, in the blower compartment of the furnace. The return air duct is typically placed on the wall, ceiling, floor or utility closet. It typically has a large metal grille that covers the filters. Ideally, the filter should be easily accessible to homeowners and service technicians to facilitate cleaning and replacement.

Filters are evaluated based on their MERV rating (Minimum Effectiveness Reporting Value) which reveals how well they can capture different sizes of particles. A low-MERV is able filter larger particles such as dust mites and pet dander but not fine allergens or germs. High-MERV filters, on contrary, are able to capture various contaminants without limiting normal airflow.
