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 create heat for the furnace while electricity powers the cooling components in an all-electric system.

Each room is equipped with vents (or registers). They are situated on the ceiling or walls, or on floors. If you can, keep them open to ensure that air is flowing properly throughout your home.


The thermostat is a crucial element of your HVAC system. It regulates the temperature of your home by switching off and on the compressor and fan until they reach a set temperature, and also turns on the air exchanger to help bring fresh air from outside into your home while exchanging stale indoor air through your ductwork.

Most thermostats are digital, although older models do exist. Digital thermostats use an instrument called a thermistor, which has metals that change electrical resistance as changes in temperature. The thermistor is connected to a controller, converts the resistance change into a temperature. Thermostats are available in range of models including programmable and intelligent thermostats that allow you to monitor your home energy consumption and adjust it accordingly.

Thermostats can be positioned on the walls of your home’s interior, typically in the rooms most often used. The location of your thermostat can affect its accuracy. A thermostat placed in direct sunlight, for example could show a higher temperature than the actual room temperature. This could cause your system to run more or less. If your thermostat isn’t operating correctly, try setting it again however if this does not resolve the issue, you should call an AC technician for assistance.

If you’re considering replacing your thermostat, check out the various options available for you, and consider a thermostat that is programmable to help save money on your energy bills. A thermostat that can be programmed will automatically adjust the temperature of your home to suit your needs instead of having you manually alter your HVAC system on a regular basis. It is also worth checking to determine if you can locate a better model that can give you more savings on energy, like an energy-efficient or ENERGY certified thermostat.


When your air conditioning isn’t performing as well as it should one of the most frequent causes is your condenser. The condenser is comprised of a number of parts that have to cooperate to ensure that the unit functions. The entire system can be affected when any of these components are damaged or worn out. The most frequent issues in the condenser include a malfunctioning control board or leaks of refrigerant.

The refrigerant gas produced by the compressor is pumped into the condenser where the fan blows cool outside air over the coils. This helps the refrigerant to reduce its temperature and then transform to a liquid. This cooled low-pressure liquid then is redirected back to the evaporator where it continues the cooling process. The process is repeated until the desired temperature in your home or business is reached.

The most important thing you can do to ensure that your condenser working effectively is to ensure that the area around it is free of debris. The condenser’s fan can draw leaves, twigs, and other debris into the unit, creating clogs and hindering the cooling system from operating effectively. It is a good idea to keep your trees and shrubs cut back so that they don’t get in the way of the unit. This will reduce the chance that berries, nuts or branches can enter the system and cause clogging. The condenser that is free of debris can add 1-2 additional years to the lifespan of your AC system.


The evaporator is a component that moves warm air into your home. It is constructed of a series u-shaped tubes, which are then set into panels. The coils are blown by air from the blower. This is a way of transferring 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 thermodynamic law states that heat moves from colder objects to warmer ones. When the evaporator functions correctly, the energy of heat is transferred from the warm refrigerant to the warm air. The refrigerant gas causes to vaporize or boil. During this process the latent heat (which is not measurable with thermometers) is transferred from air to refrigerant.

These coils are constructed with special structures that enhance the transfer of heat. These are known as fins, and they expand the surface area to aid in the transfer of heat. Certain evaporators are constructed with copper while others use aluminum, each offering its own set of advantages.

One of the most common problems with an evaporator is an accumulation of organic growth. This could be the result of mold or mildew. If this is the case, the foul smells caused by the bacteria will be spread throughout the house and may cause discomfort.

It is crucial to choose an evaporator that is easily maintained and cleaned. When choosing an evaporator, it is essential to think about the working environment. Some are designed to withstand harsh environments, whereas others can work well in moderate conditions. Also, you’ll want to ensure that your evaporator is covered by a solid guarantee that will ensure your investment.


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 that you keep the fan on constant to maximize efficiency and reduce your electric bills. We can replace the motor of the fan if it is constantly running. The new ECM motor is 70 percent more efficient than the previous PSC motors. It will pay for itself over the lifespan of the unit.

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


Air flows through the filter, before being heated or cooled before being circulated throughout the home. It removes impurities and keeps dust and pet dander from getting into the system and contaminating the internal components. It safeguards the family members from illnesses caused by airborne pathogens. It also ensures that the system is working efficiently. A dirty filter causes the system to work harder, which could cause it to overheat and eventually break down.

homeowners should change their filters frequently each 30 days or 90 days, depending on the instructions on the label. A homeowner should consult a HVAC professional in case they are not sure of the type of filter they need. A professional can help homeowners select the best filter for their home, based on factors like climate, how often they use their system and even personal preferences, like whether there are allergy sufferers in the home.

The filter is typically located at the return air duct, or in some cases, the blower compartment of the furnace. The return air duct can be located on the wall, floor or ceiling, or in a in the utility closet. It usually has a large, metal grate which covers the filter. The filter should be easily accessible to homeowners and technicians for easy cleaning and replacement.

Filters are evaluated based on the MERV (Minimum Efficiency Reporting Value) rating, which shows how effective they are at collecting 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, but it’s not very efficient in catching small allergens or germs. High-MERV filters, on the contrary, are able to capture a wide range of contaminants without limiting normal airflow.
