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 in an all-electric HVAC unit uses propane or oil, or natural gas to heat the furnace.

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

Thermostat

The thermostat is an essential part of your HVAC system. It regulates the temperature in your home by switching on and off 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.

The majority of thermostats are digital. However older models are available. Digital thermostats are controlled by the thermostat. The device is made of metals that change resistance when the temperature changes. The thermistor is linked to an microcontroller that converts changing resistance into the temperature reading. Thermostats are available in range of models including programmable and intelligent thermostats that allow you to monitor your home energy consumption and make adjustments.

Thermostats can be placed on the walls of your home’s interior, usually in rooms that are most often used. The place of your thermostat will affect its accuracy. A thermostat located in direct sunlight, for instance could show an upper temperature than the actual room temperature. This can cause your system to operate more or less. If your thermostat isn’t operating correctly, try reset it however if this does not resolve the issue it is recommended to contact an AC technician for assistance.

If you’re considering replacing your thermostat, check out the different options available to you and think about a programmable model to reduce your energy costs. A programmable thermostat will automatically adjust your home’s temperature to suit your needs, rather than having you manually manipulate your HVAC system on a regular basis. You should also check to see if there is an energy-efficient model, such as one that’s ENERGY A STAR-certified or energy-efficient.

Condenser

If your air conditioner isn’t working as efficiently as it ought to, one of the most frequent causes can be found in your condenser. The condenser is made up of a variety of parts that all need to work in harmony for the unit to work. The entire system could be affected when any of these components are damaged or worn out. The most frequent issues in the condenser are a broken control board or leaks of refrigerant.

The refrigerant gas from the compressor is pushed into the condenser, where a fan blows cool air from outside over the coils. This helps the refrigerant get cool and transform to a liquid state. The liquid that is cooled moves back into the evaporator to continue the cooling process. The process is repeated until the desired temperature for your business or home is reached.

To keep your condenser running properly, you should ensure that the area surrounding it is clear of debris. The condenser’s fans can draw leaves, twigs, and other debris into the unit, causing clogs and hindering the cooling system from operating effectively. It is also a good idea to keep the bushes and trees cut back so that they don’t encroach on the unit. This will decrease the chances that berries, nuts or branches can fall into the system and cause clogging. Keeping your condenser free from debris can add 1-2 additional years to the lifespan of your AC system.

Evaporator

The evaporator is the part that moves warm air into your home. It is constructed of a series of u-shaped tubes that are set into panels. Air from the blower fans is blown across these coils. This draws heat from the indoor air and transfers it 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 heat is transferred from colder to warmer objects. If the evaporator operates correctly, this heat energy is transferred from warm air to the colder refrigerant. This causes the refrigerant to boil or evaporate. During this process, the heat that cannot be measured with thermometers, referred to as latent heat is transferred from air to the refrigerant.

These coils have been created with specific shapes that improve heat transfer. Fins are utilized to increase the surface area of the coils. Both aluminum and copper are utilized to construct Evaporators, each with their own advantages.

An evaporator that is afflicted with an accumulation of organic growth is prone to issues. This could be caused by mildew or even mold. If this happens, the bacterium will produce a smell that spreads throughout the home. This could cause discomfort.

To avoid these problems, it is essential to select an evaporator which can be easily cleaned and maintained. It is also an ideal idea to take into consideration the working environment when selecting an evaporator. Certain evaporators are designed to withstand harsh environments, while others are suited to moderate environments. You should also make sure that the evaporator you choose to purchase is covered by a warranty that will protect you and your investment.

Fan

Your HVAC system’s blower motor works to circulate the hot or cold air throughout your home until the thermostat you have set is attained. The fan can either be set to auto or constant. We suggest keeping the fan running on a constant basis to maximize efficiency and save money on your electricity bills. If your system’s fan is continuously running, we can replace it with a brand new ECM blower motor, which is up to 70 percent more efficient than the old PSC motors and pays for itself in savings over the duration of the unit.

If your fan is running on the high setting, a malfunctioning relay switch or short circuit may be blocking the settings you set on the thermostat from reaching the fan.

Filter

The air passes through the filter before being warmed or cooled and circulated around the home. It filters out impurities and stops dust and pet dander out of the system and contaminating the internal components. It also shields family members from diseases spread by tiny pathogens that are floating in the air. It also ensures the system is functioning properly. A dirty filter makes the system work harder and can cause it to overheat or break down.

homeowners should change their filters regularly at least every 30 days or 90 days, depending on the directions on the label. A homeowner should seek advice from an HVAC professional when they aren’t sure about the kind of filter they require. A professional can assist homeowners select the appropriate filter for their home, based on factors like temperature, how often they use their system, and even personal preferences, like whether there are allergy or smokers sufferers in the home.

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 is typically placed on the wall, ceiling or floor, or in the utility closet. It often has a large grille made of metal that covers the filters. The filter should be accessible to both homeowners and technicians for easy cleaning and replacement.

Filters are rated according to their MERV rating (Minimum Effectiveness Reporting Value) which indicates how well they are able to capture various sizes of particles. A filter with a low MERV rating is able to remove larger particles such as pet dander and dust mites, but it’s not very effective in capturing fine allergens or germs. High-MERV filters, on the other hand, can catch many different contaminants without limiting normal airflow.
