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, oil, or natural gas as fuel to heat the furnace.

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

Thermostat

A thermostat is among the most vital components of your HVAC system. It regulates the temperature in your home by turning on and shutting off the fan and compressor to attain a pre-set temperature. It also turns on the exchanger to pull fresh air from outside your home and then vent stale air through your ductwork.

The majority of thermostats are digital although some older models still exist. Digital thermostats are controlled by a thermistor. The device contains metals which change resistance as temperatures change. The thermistor, connected to a control unit, converts the resistance change into a temperature. Thermostats come in a variety of styles including programmable and intelligent thermostats that allow you to monitor your home’s energy consumption and make adjustments.

Thermostats are placed on the walls of your home, usually in rooms where they are most frequently used. The place of a thermostat within your home could affect its accuracy. For example one thermostat placed in direct sunlight might be more hot than the actual room temperature which can cause your system to run excessively or not run at all. If your thermostat doesn’t work properly, try resetting the device. If this doesn’t solve the problem, call an AC technician.

Consider a programmable thermostat when you are replacing your current thermostat. You can save money on energy bills. A programmable model will automatically adjust the temperature of your home according to your schedule, instead of requiring you to manually manipulate your HVAC system every day. You should also find out if there’s an energy-efficient model, such as one that’s ENERGY A STAR-certified or energy-efficient.

Condenser

Condensers are often the culprit when your air conditioner isn’t working properly. The condenser unit is comprised of numerous components that must be working in sync for the unit to work. The entire system may be affected when any of these components are damaged or worn out. Problems with the condenser include a malfunctioning control board for the condenser, 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 helps the refrigerant cool down and convert back to a liquid. The low-pressure liquid is chilled and then returned to the evaporator to continue the cooling process. The process is repeated until it reaches the desired temperature for your home or office.

The most important thing you can do to keep your condenser operating effectively is to ensure that the area around it stays free of any debris. The condenser’s fan can draw leaves, twigs, and other debris into the unit, causing clogs and preventing the cooling system from working properly. It is also a good idea to keep the bushes and trees trimmed so that they don’t cause obstruction on the unit. This can reduce the possibility that berries, branches, or nuts will fall on the system and cause a blockage. Cleaning your condenser of debris can add 1-2 additional years to the life of your AC system.

Evaporator

The evaporator moves warm air in your home. It is comprised of a series u-shaped tubes, which are then set into panels. The air from the blower fan is blown across these coils. This transfer heat from the indoor environment to the refrigerant. The refrigerant liquid is transformed into a gas and circulated throughout the cooling system to cool your indoor air.

The thermodynamic law states that heat travels from warmer to colder objects. When the evaporator operates correctly, the heat energy is transferred from the refrigerant that is warm to the warm air. This causes the refrigerant’s water to boil or evaporate into gas. During this process, the heat that is not measured by a thermometer, known as latent heat, is transferred from the air to the 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 their own advantages.

One of the most common problems with an evaporator is an accumulation of organic growth. This can be a result of mold or mildew. If this happens, the bacteria can produce a foul smell that will spread throughout the house. This may cause discomfort.

It is essential to choose an evaporator which can be easily maintained and cleaned. It is also an ideal idea to take into consideration the environment in which you work when choosing an evaporator. Some are built to withstand harsh environments, whereas others can work well in moderate environments. In the end, you’ll want to ensure that your evaporator comes with a solid guarantee that will ensure your investment.

Fan

The blower fan of your HVAC system circulates cold or hot air through your home until you reach the temperature setting. The fan can be set to auto or constant. We recommend keeping the fan running constant for maximum efficiency and to save money on electricity costs. 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 pays for itself in savings over the duration of the unit.

If your fan only operates on high, a short circuit or a broken relay could be keeping the thermostat settings from reaching the fan.

Filter

The filter is used to circulate air around the house before it is heated or cool. It eliminates impurities and prevents dust and pet dander from getting into the system to contaminate internal components. It safeguards the family from illness spread by airborne pathogens. It also ensures that the system functions efficiently. A dirty filter makes the system work harder and may cause it to overheat or break down.

homeowners should change their filters frequently – every 30 days or 90 days, depending on the instructions on the label. A homeowner should consult a HVAC professional when they aren’t sure of the type of filter they require. A professional can assist them in selecting the right filter for their home based on the climate and the amount of time they use their system, and other personal factors such as the presence of allergy sufferers or smokers within the home.

The filter is usually located in the return air duct or, in certain cases, in the blower compartment of the furnace. The return air duct is normally placed on the wall, ceiling or floor, or in the in the utility closet. It usually has a large grille made of metal that covers the filters. Ideally, the filter should be easily accessible to homeowners and service technicians in order 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 will be able to filter larger particles such as dust mites or pet dander but not fine allergens and germs. High-MERV filters, on other hand, can catch various contaminants without restricting normal airflow.
