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 makes use of propane, oil or natural gas to generate heat for the furnace, while electricity powers the cooling components in an all-electric system.

Vents (or registers) are found in the ceiling or on the floor of every room. It is recommended to keep them open to allow proper air flow throughout your home.

Thermostat

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

Most thermostats are digital, although some older models still exist. Digital thermostats are controlled by a thermostat. The device contains metals that alter resistance when the temperature changes. The thermistor is linked to an microcontroller that converts changing resistance into an indication of 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 located on the interior walls of your house, typically in rooms where they are used the most. The location of your thermostat can affect its accuracy. For instance the thermostat that is located in direct sunlight might appear hotter than the actual room temperature which can cause your system to overrun or not even run at all. If your thermostat isn’t working properly, try resetting the device. If this doesn’t work then contact an AC technician.

If you’re considering replacing your thermostat, check out the different options available to you and think about the possibility of a programmable thermostat to save money on your energy bills. A programmable model will automatically adjust the temperature of your home according to your schedule, instead of having to manually adjust your HVAC system every day. It’s also worth a look to determine if you can locate a better model that can offer you even more energy savings, like an energy-efficient or ENERGY certified thermostat.

Condenser

If your air conditioner isn’t working as efficiently as it should, one of the most common causes can be found in your condenser. The condenser unit is comprised of many different parts that all need to be functioning in harmony for the unit to work. If any of these components get damaged or worn out, then the entire system may be affected. Condenser problems include a broken control board for the condenser, or leaks of refrigerant.

The compressor pushes the refrigerant through the condenser where a fan blows cool outside air over the coils. This allows the refrigerant gas to cool, and return to a liquid state. The liquid that is cooled moves back into the evaporator, where it continues the cooling process. The cycle is repeated until the desired temperature for your business or home is achieved.

The most important thing you can do to keep your condenser operating properly is to make sure that the area around it stays clear of debris. The condenser’s fan could draw leaves, twigs, and other debris into the unit, creating obstructions and hindering the cooling system from functioning properly. It is recommended to keep trees and bushes in good shape so that they don’t encroach on the unit. This will reduce the possibility that branches, berries or even nuts fall on the system and cause a blockage. Keep your condenser in good condition to extend the life of your AC system by 1-2 years.

Evaporator

The evaporator is used to move warm air around your home. It is constructed of a series of u-shaped tubes that are arranged into panels. The air from the blower fan is blown through these coils. This transfer heat from the indoor air to the refrigerant. The refrigerant’s liquid is converted into a gas and 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. When the evaporator is operating properly, the heat energy passes from the warm air to the refrigerant that is colder. This causes the refrigerant’s water to boil or evaporate into gas. In this process, heat that is not measured with thermometers, referred to as latent heat is transferred from the air to the refrigerant.

The coils are designed with specific shapes that improve heat transfer. They are referred to as fins, and expand the surface area to help in the transfer of heat. Aluminum and copper are both used to build some Evaporators, each with its own advantages.

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

It is essential to choose an evaporator that can be easily maintained and cleaned. When choosing an evaporator, it is crucial to consider the working environment. Certain models are designed to withstand harsh conditions while others can work well in moderate conditions. It is also important to make sure that the evaporator you choose to purchase is protected by a warranty which will protect you and your investment.

Fan

The blower fan of 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 recommend keeping the fan running at all times for maximum efficiency and to cut down on electric bills. We can replace the fan motor if it is constantly running. The new ECM motor is up to 70 percent more efficient than the old PSC motors. It will pay for itself over the life of the unit.

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

Filter

Air passes through the filter before being warmed or cooled, and then circulated throughout the home. It removes impurities and prevents dust and pet dander getting into the system and contaminating internal components. It protects the family from illnesses spread by airborne pathogens. It also ensures that the system is working efficiently. A dirty filter causes the system to perform more efficiently, which could cause it to overheat and ultimately break down.

Homeowners should replace their filters regularly each 30 or 90 days, based on the instructions on the label. A homeowner should consult a HVAC professional if they are unsure of the type of filter they need. A professional can help homeowners select the appropriate filter for their home, in light of factors like climate, how often they use their system, and even personal preferences, such as whether there are smokers or allergy sufferers living in the home.

The filter is usually found in the return air duct or, in some cases, the blower compartment of the furnace. The return air duct is usually located on the ceiling, wall, floor or storage closets. It usually has a large grille made of metal that protects the filters. The filter should be easily accessible to both homeowners and technicians for easy cleaning and replacement.

Filters are rated based on their MERV rating (Minimum Effectiveness Reporting Value), which shows how well they 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 isn’t very effective at catching fine allergens or germs. High-MERV filters, on the contrary, can capture various contaminants without limiting normal airflow.
