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.

Each room has vents (or registers). They are located on the ceiling, walls or floors. They should be kept open as much as you can to ensure the proper circulation of air throughout your home.

Thermostat

The thermostat is an essential element of your HVAC system. It regulates the temperature of your home by turning on and shutting off the compressor and fan until they attain a pre-set temperature. It also turns on the exchanger to draw fresh air from outside your home and then vent stale air through your ductwork.

The majority of thermostats are digital. However, older models do exist. Digital thermostats use a device called a thermistor, which has metals that change electrical resistance as temperature changes. The thermistor is connected an electronic microcontroller, which converts the changing resistance into an indication of temperature. There are a variety of thermostats, including smart and programmable thermostats. They let you monitor and adjust your home’s energy consumption.

Thermostats can be positioned on the walls of your home’s interior. They are usually in the rooms that are most frequently used. The position of your thermostat could affect its accuracy. For instance one thermostat placed in direct sunlight may be more hot than the actual room temperature which can cause your system to overrun or not operate at all. If your thermostat isn’t functioning correctly, you can try resetting it but if that does not solve the issue it is recommended to contact an AC technician for help.

If you’re thinking of replacing your thermostat, be sure to check out the various options available and think about the possibility of a programmable thermostat to reduce your energy bills. A thermostat that is programmable will automatically adjust your home’s temperature to suit your needs, rather than having you manually adjust your HVAC system on a regular basis. You should also see if there is an energy-efficient model, for instance one that’s ENERGY 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 could be affected in the event that any of these parts are damaged or worn out. The most common problems found in the condenser include a broken control board or refrigerant leaks.

The refrigerant gas that is produced by the compressor is pushed into the condenser, where fans blow cool air from outside over the coils. This allows the refrigerant gas to cool, and return to a liquid form. The liquid that is cooled moves back into the evaporator, where it continues the cooling process. The process continues until the desired temperature in your home or business is achieved.

The most important thing you can do to keep your condenser working effectively is to ensure that the area around it is free of debris. The condenser’s fan could pull leaves, twigs and other debris into the unit, creating clogs and hindering the cooling system from operating efficiently. It’s also a good idea to keep the trees and shrubs trimmed so they don’t touch the unit. This will reduce the chance that nuts, berries or branches get into the system and clog it. Keep your condenser in good condition to extend the life of your AC system by a couple of years.

Evaporator

The evaporator is the part that circulates warm air into your home. It is comprised of a series of tubing which is u-shaped, and placed into panels. The coils are being blown by the air of the blower. This draws heat from indoor air and then transfers it to the refrigerant. The refrigerant liquid is transformed into a gas, then circulated throughout the cooling system in order to cool your indoor air.

The law of thermodynamics states that heat travels from colder objects to warmer ones. When the evaporator is operating correctly, this heat energy passes from the warm air to the colder refrigerant. This causes the refrigerant to heat up or evaporate into a gas. In this process, the latent heat (which is not measurable with thermometers) 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. Some evaporators are built using copper, while others are made of aluminum, with each material offering its own set of advantages.

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

To avoid these issues, it is important to choose an evaporator which can be easily cleaned and maintained. It is also an ideal idea to take into consideration the environment in which you work when choosing an evaporator. Certain models are designed to withstand harsh conditions, while others can be used in moderate environments. You will also want to make sure that your evaporator is protected by a warranty that will safeguard you and your investment.

Fan

The fan that blows air in your HVAC system circulates hot or cold air through your home until you get to the temperature you want. The fan can either be set to auto or constant. We recommend that you keep the fan on constant to maximize efficiency and save money on your electricity bills. We can replace the fan motor if it is constantly running. The new ECM motor is up to 70 percent more energy efficient than the older PSC motors. It will pay for itself over the lifetime of the unit.

If your fan is running on the high setting, a broken relay switch or short circuit could be hindering the settings you input on the thermostat from reaching your fan.

Filter

The air passes through the filter before it is heated or cooled before being circulated around the home. It removes impurities, and prevents dust and pet dander from entering into the system and contaminating internal components. It protects the family from illness spread by airborne pathogens. It also ensures the system is functioning properly. A dirty filter causes the system to perform more efficiently, which could cause it to overheat and ultimately break down.

Homeowners should change their filters regularly. The label will tell them whether they should do it every 30 days or every 90 days. If a homeowner isn’t certain what kind of filter they should use, they should consult an HVAC professional. A professional can assist them in selecting the right filter for their home based on the climate, how much they run their system, and personal factors like the presence of allergy sufferers or smokers in the house.

The filter is situated in the return air duct, or in some cases the blower compartment of the furnace. The return air duct is typically placed on the wall, ceiling or floor, or in the in the utility closet. It typically has a large grille made of metal that protects the filters. Ideally, the filter is accessible to homeowners and service technicians to aid in cleaning and replacement.

Filters are assessed based on the MERV (Minimum Efficiency Reporting Value) rating, which shows how effective they are at taking in different sizes of particles. A filter with a low MERV rating can be used to remove larger particles such as pet dander and dust mites however it’s not as efficient in catching small allergens or germs. High-MERV filters, on other hand, can catch a wide range of contaminants without restricting normal airflow.
