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 as fuel to heat the furnace.

Vents (or registers) are located in the ceiling or wall of each room. You should keep them open as much as you can to ensure that air circulation is maintained throughout your home.

Thermostat

The thermostat is an essential component of your HVAC system. It regulates the temperature in your home by turning off and on the fan and compressor until they reach a set temperature, and also turns on the air exchanger to help pull fresh, outside air into your home, while exchanging stale indoor air out 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 temperatures change. The thermistor, which is connected to a control unit, converts the resistance change into a temperature. There are many types of thermostats, including smart and programmed thermostats. They allow you to monitor and alter your home’s energy consumption.

Thermostats are installed on the interior walls of your house, typically in rooms where they are used the most. The location of a thermostat in your home may affect its accuracy. A thermostat placed in direct sunlight, for instance, may show a higher temperature than the actual temperature of the room. This could cause your system to run more or less. If your thermostat doesn’t work properly, try resetting the device. If this doesn’t work contact an AC technician.

Consider a programmable thermostat when you are replacing your existing thermostat. You will save money on your energy bills. A programmable model will automatically adjust the temperature of your home according to your schedule, instead of needing you to manually operate your HVAC system on a daily basis. It is also advisable to determine if there’s an efficient model, like one that is ENERGY STAR certified or energy-efficient.

Condenser

When your air conditioning isn’t performing as well as it is supposed to one of the most common causes can be found in your condenser. The condenser is made up of several parts that must be in sync to ensure that the unit functions. The entire system may be affected when any of these components are damaged or worn out. The most common issues found in the condenser include a broken control board or leaks of refrigerant.

The compressor moves the refrigerant into the condenser, which is where a fan blows cooled outside air over the coils. This allows the refrigerant gas to cool and return to liquid form. This liquid at low pressure is removed and cooled before being moved back into the evaporator to continue the cooling process. The process is repeated until it reaches the desired temperature for your office or home.

The most important thing you can do to ensure that your condenser working properly is to make sure that the area around it stays clear of debris. Leaves, twigs, flowers, grass and other debris could be sucked into the unit by the condenser fan. This can create clogs that hinder the operation of the cooling system. It is a good idea to keep your trees and shrubs cut back so that they don’t encroach onto the unit. This will decrease the chances that nuts, berries or branches will fall into the system and block it. The condenser that is free of debris can add 1-2 additional years to the lifespan of your AC system.

Evaporator

The evaporator is the part that circulates warm air into your home. It is made of a string of tubing that is shaped like a U and then placed into panels. The coils are blown by air from the blower. This transfer heat from the indoor environment to the refrigerant. The refrigerant liquid is transformed into a gas, then circulated throughout the cooling system in order to cool the indoor air.

The law of thermodynamics states that heat is transferred from colder objects to warmer ones. If the evaporator is operating correctly, this heat energy is transferred from warm air to the refrigerant that is colder. This causes the refrigerant gas to boil or evaporate. In this process, heat that is not measured with a thermometer, known as latent heat is transferred from the air to the refrigerant.

These coils are designed 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 build some Evaporators, each with its own advantages.

An evaporator that is afflicted with an accumulation of organic growth can be prone to issues. This can be a result of mildew or mold. If this is the case, the foul smells caused by the bacteria can be absorbed by the home and can cause discomfort.

To avoid these issues, it’s essential to select an evaporator that is easily cleaned and maintained. When choosing an evaporator, it is crucial to think about the working environment. Certain models are designed to withstand harsh environments, whereas others can be used in moderate environments. Lastly, you will want to make sure your evaporator is covered by a solid warranty to ensure your investment.

Fan

The fan that blows air in your HVAC system circulates cold or hot air in your home until you get to the temperature you want. The fan can be set to auto or constant. We recommend keeping the fan running continuously to maximize efficiency and save money on your electricity bill. If your system’s fan is continuously running, we can replace it with a new ECM blower motor which is up to 70 percent more efficient than older PSC motors and will pay for itself in savings over the lifetime of the unit.

If your fan only runs on high, an unbalanced circuit or a broken relay could be keeping your thermostat settings from reaching your fan.

Filter

Air passes through the filter before being heated or cooled before being circulated around the house. It removes impurities, and also stops dust and pet dander from entering into 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 functions efficiently. A dirty filter can cause 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 inform them whether they should do it every 30 days or every 90 days. If a homeowner isn’t sure which kind of filter they should use, they should consult an HVAC professional. A professional can help homeowners choose the right filter for their home, in light of factors like the climate, the frequency they use their system and even personal factors such as whether there are smokers or allergy sufferers living in 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 usually has a large metal grille that protects the filters. The filter should be easily accessible to homeowners and service technicians to aid in cleaning and replacement.

Filters are rated based on their MERV rating (Minimum Effectiveness Reporting Value) which reveals how well they can capture different sizes of particles. A filter with a low MERV rating can be used to capture larger contaminants such as pet dander and dust mites, but it’s not very effective in capturing fine allergens or germs. High-MERV filters are able to capture various contaminants, but it doesn’t affect the flow of air.
