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 to generate heat for the furnace, while electricity powers the cooling elements in an all-electric system.

Every room has vents (or registers). They are located on the ceiling or walls, or floors. If you can you can keep them open to ensure that air circulation is properly distributed throughout your home.

Thermostat

A thermostat is one of the most crucial components of your HVAC system. It regulates the temperature of your home by turning off and on the compressor and fan until they reach a set temperature. It also switches on the air exchanger to help pull fresh, outside air into your home, while venting old, indoor air through your ductwork.

The majority of thermostats are digital. However there are older models. Digital thermostats make use of an instrument called a thermistor made of metals that change electrical resistance as changes in temperature. The thermistor is connected to an electronic microcontroller, which converts the changing resistance into the temperature reading. Thermostats come in a variety of styles including programmable and intelligent thermostats that let you track your home’s energy usage and adjust it accordingly.

Thermostats are often placed on the walls of your home’s interior, typically in the rooms most frequently used. The position of your thermostat could affect its accuracy. A thermostat that is placed in direct sunlight, for instance could show a higher temperature than the actual room temperature. This could cause your system to operate more or less. If your thermostat isn’t functioning correctly, try resetting the device. If this doesn’t work then contact an AC technician.

If you’re thinking of replacing your thermostat, be sure to check out the different options available and think about the possibility of a programmable thermostat to reduce your energy costs. A programmable thermostat will automatically adjust your home’s temperature according to your schedule instead of having to manually adjust your HVAC system on a regular basis. It’s also worth checking to see if you can find an alternative that will give you more energy savings, like an energy-efficient or ENERGY A STAR-certified thermostat.

Condenser

Condensers are usually the cause when your air conditioner isn’t working as well as it should. The condenser is made up of a variety of parts that all need to be working in sync for the unit to function. If any of these parts become damaged or wear out, then the entire system can be impacted. Condenser problems include a broken control board for the condenser or leaks of refrigerant.

The refrigerant gas from the compressor is pumped into the condenser where the fan blows cool outside air over the coils. This allows the refrigerant gas to cool, and return to liquid form. This low-pressure liquid is then removed and cooled before being transferred back into the evaporator to continue cooling. The process continues until the temperature you want in your home or business is reached.

To ensure that your condenser is operating correctly, you must ensure that the area surrounding it is clean of any debris. The condenser’s fan could pull leaves, twigs and other debris into the unit, causing blockages and preventing the cooling system from functioning efficiently. It’s also a good idea to keep bushes and trees trimmed to ensure that they don’t get on the unit. This can reduce the risk that berries, branches, or even nuts fall and block the system. The condenser that is free of debris can add 1-2 additional years to the life of your AC system.

Evaporator

The evaporator is what moves warm air in your home. It is made of a series of u-shaped tubes that are arranged into panels. The coils are blown by air from the blower. This transfer heat from the indoor environment to the refrigerant. The refrigerant’s liquid is converted into a gas, then circulated throughout the cooling system to cool the indoor air.

The law of thermodynamics states heat travels from warmer to colder objects. When the evaporator operates correctly, the energy of heat is transferred from the refrigerant that is warm to the warm air. This causes the refrigerant’s water to boil or evaporate into a gas. During this process the latent heat (which cannot be measured using a thermometer) is transferred from the air to the refrigerant.

These coils are designed with special structures that enhance the transfer of heat. These are also known as fins and increase the surface area to aid in the transfer of heat. Aluminum and copper are both used to build some Evaporators, each with distinct advantages.

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

To avoid these issues, it is crucial to choose an evaporator that is easily cleaned and maintained. When choosing an evaporator, it is crucial to take into consideration the environment in which it will be operating. Some are built to withstand harsh environments, whereas others can be used in moderate environments. You should also make sure that your evaporator is protected by a warranty that will safeguard you and your investment.

Fan

Your HVAC system’s blower fan functions to circulate cool or hot air through your home until the thermostat setting you set is reached. 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 bills. We can replace the motor of the fan when it is running continuously. The new ECM motor is 70 percent more energy efficient than the previous PSC motors. It pays for itself over the life of the unit.

If your fan is operating at the highest setting, a damaged relay switch or short circuit may be preventing the settings you enter on the thermostat from reaching your fan.

Filter

Air flows through the filter before being warmed or cooled, and then circulated around the house. It removes impurities and also stops dust and pet dander from getting into the system, causing contamination to internal components. It safeguards the family from illness spread by airborne pathogens. It also ensures that the system is operating efficiently. A dirty filter can make the system work harder and could cause it to overheat or even to fail.

The homeowner should change their filters frequently at least every 30 days or 90 days, depending on the instructions on the label. A homeowner should consult a HVAC professional if they are unsure about the kind of filter they require. A professional can help homeowners select the best filter for their home based on factors like the climate, the frequency they use their system and even personal factors, for instance, whether there are allergy or smokers sufferers living in the home.

The filter is situated 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 in the utility closet. It usually has a large metal grille that covers the filters. The filter should be easily accessible for homeowners and service technicians to aid in 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 low-MERV is able capture larger contaminants such as dust mites or pet dander but not fine allergens and germs. High-MERV filters can snag various contaminants without affecting the normal flow of air.
