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. Its blower uses propane or natural gas, or oil to create heat for the furnace while electricity powers the cooling components in an all-electric unit.

Each room has vents (or registers). They are located on the ceiling or walls, or floors. It is recommended to keep them open to allow that air circulation is maintained throughout your home.

Thermostat

A thermostat is one of the most vital components of your HVAC system. It regulates the temperature of your home by turning on and shutting off the compressor and fan until they achieve a set temperature. It also activates the exchanger in order to draw fresh air from outside into your home and vent stale air through your ductwork.

The majority of thermostats are digital although some older models still exist. Digital thermostats are controlled by a thermosistor. The device is made of metals that alter resistance as temperature changes. The thermistor, connected to a controller converts the resistance change into a temperature. Thermostats are available in a range of models including programmable and intelligent thermostats that let you monitor your home energy consumption and make adjustments.

Thermostats are installed on the walls of your home, typically in rooms that are most frequently used. The position of your thermostat could affect its accuracy. For instance, a thermostat located in direct sunlight may appear hotter than the actual room temperature, causing your system to run too much or not operate at all. If your thermostat isn’t working properly, you can try resetting it, but if this does not resolve the issue it is recommended to contact an AC technician for assistance.

If you’re thinking about changing your thermostat, you should check out the various options available to you and consider a thermostat that is programmable to help save money on your energy costs. A programmable model will automatically adjust the temperature of your home according to your preferences, rather than needing you to manually operate your HVAC system each day. You should also check to find out if there’s an efficient model, such as one that’s ENERGY STAR certified or energy-efficient.

Condenser

Condensers are often the culprit when your air conditioner isn’t functioning as well as it should. The condenser consists of several parts that must work together to function. If any of these parts become damaged or wear out, the whole system may be affected. Condenser issues can include a damaged control board for the condenser, or leaks of refrigerant.

The compressor pushes the refrigerant into the condenser, where a fan blows cooled outside air over the coils. This allows the refrigerant gas to cool, and return to a liquid state. The liquid that is cooled returns to the evaporator to continue the cooling process. The process is repeated in order to reach the desired temperature for your home or office.

The most important thing you can do to keep your condenser running effectively is to ensure that the area around it stays free of any debris. The condenser’s fan can pull leaves, twigs and other debris into the unit, creating obstructions and preventing the cooling system from operating efficiently. It’s recommended to keep bushes and trees in good shape so that they don’t cause obstruction on the unit. This will reduce the chance that berries, nuts, or branches can fall into the system and clog it. The condenser that is free of debris can add an additional 1-2 years to the life of your AC system.

Evaporator

The evaporator is what is used to move warm air around your home. It is made of a series of u-shaped tubes that are arranged into panels. The air from the blower fan is blown through these coils. This is a way of transferring heat from the indoor atmosphere to the refrigerant. The refrigerant’s liquid becomes an air-borne gas that is circulated through the cooling system to cool your air.

The thermodynamic law states that heat moves from warmer to colder objects. If the evaporator is operating correctly, the energy of heat is transferred from the warm refrigerant to the cold air. The refrigerant gas causes to boil or evaporate. In this process, the latent heat (which cannot be measured with thermometers) is transferred from the air to the refrigerant.

These coils have been designed with special shapes that aid in heat transfer. Fins are utilized to increase the surface area of the coils. Aluminum and copper are both used to build some evaporators, each with its own advantages.

A evaporator with an accumulation of organic growth is prone to problems. This could be the result of mold or mildew. If this is the case, the foul smells caused by the bacteria will be spread throughout the house and could cause discomfort.

It is essential to choose an evaporator that can be easily cleaned and maintained. It is also a good idea to consider the working environment when selecting an evaporator. Some evaporators are built to withstand harsh environments, while others can be used in moderate conditions. Also, you’ll want to ensure that your evaporator comes with a solid guarantee that will ensure your investment.

Fan

The fan in your HVAC system circulates hot or cold air in your home until you reach the temperature setting. The fan can be turned on automatic or constant. We suggest keeping the fan on constant for maximum efficiency and to save money on electricity bills. If your system’s fan is continuously running we can replace it with a 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 highest setting, a malfunctioning relay switch or short circuit may 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 cooling. It removes impurities, and stops dust and pet dander getting into the system and contaminating internal components. It also shields family members from the spread of diseases by tiny pathogens floating in the air. It also ensures that the system works efficiently. A dirty filter can make the system work harder and may cause it to overheat or break down.

homeowners should change 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 sure which kind of filter they need, they should consult an HVAC professional. A professional can assist them in selecting the right filter for their home based on climate and the amount of time they use their system, and personal factors such as the presence of smokers or allergies in the house.

The filter is usually found at the return air duct, or in certain cases, in the blower compartment of the furnace. The return air duct could be located on the floor, wall or ceiling, or in a storage closets, and it often contains a large metal grate that covers the filter. Ideally, the filter is accessible to homeowners and service technicians to facilitate cleaning and replacement.

Filters are assessed based on 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 can be used to capture larger contaminants such as dust mites and pet dander, but it’s not very effective in capturing fine allergens or germs. High-MERV filters can snag various contaminants while not affecting the flow of air.
