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 system uses propane or oil as well as natural gas as fuel to heat the furnace.

Vents (or registers) are found in the ceiling or wall of each room. They should be kept open if possible to ensure proper air flow throughout your home.

Thermostat

The thermostat is an important 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 activates the exchanger 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 use the thermistor device which is made up of metals that alter the electrical resistance when temperature changes. The thermistor is connected to an microcontroller that converts changing resistance into the temperature reading. Thermostats are available in variety of styles that include programmable and smart thermostats that allow you to monitor your home energy consumption and adjust it accordingly.

Thermostats are installed on the interior walls of your house, typically in rooms that are most frequently used. The place of your thermostat will affect its accuracy. For example one thermostat placed in direct sunlight may read hotter than the actual room temperature, causing your system to run too much or not run at all. If your thermostat isn’t operating correctly, you can try setting it again but if that does not resolve the issue then you should contact an AC technician for help.

Consider a programmable thermostat when you are replacing your existing thermostat. You will save money on your energy bills. A programmable model will automatically adjust the temperature of your home according to your schedule rather than requiring you to manually manipulate your HVAC system every day. It’s also worth a look to see if you can find an alternative that will give you more energy savings, like an energy-efficient or ENERGY STAR-certified thermostat.

Condenser

When your air conditioning isn’t functioning as efficiently as it is supposed to, one of the most frequent causes can be found in your condenser. The condenser consists of several parts that must be in sync to ensure that the unit functions. The entire system could be affected when any of these components are damaged or worn out. The most frequent issues in the condenser include a broken control board or refrigerant leaks.

The refrigerant gas that is produced by the compressor is pumped into the condenser where the fan blows cool air from outside over the coils. This allows the refrigerant gas to cool and return to a liquid state. This cooled low-pressure liquid then moves back into the evaporator where it continues the cooling process. The process is repeated in order to reach the temperature you desire for your home or office.

The most important thing you can do to ensure that your condenser running correctly is to ensure that the area around it is free of any debris. The condenser’s fans can pull leaves, twigs and other debris into the unit, causing blockages and hindering the cooling system from working efficiently. It’s also a good idea to keep the trees and shrubs well-trimmed so that they don’t get in the way of the unit. This will reduce the chance that berries, nuts or branches can get into the system and cause clogging. Clean your condenser to prolong the lifespan of your AC by a couple of years.

Evaporator

The evaporator circulates warm air inside your home. It is comprised 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 liquid is transformed into a gas and circulated throughout the cooling system in order to cool your indoor air.

The law of thermodynamics states heat travels from colder objects to warmer ones. When the evaporator is operating properly, the heat energy is transferred from warm air to the colder refrigerant. The refrigerant gas causes to boil or evaporate. During this process the latent heat (which cannot be measured with a thermometer) is transferred from air to refrigerant.

The coils are made with special structures that enhance the transfer of heat. Fins are utilized to increase the surface area of coils. Aluminum and copper are both utilized to construct Evaporators, each with their own advantages.

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

It is essential to choose an evaporator that is easily cleaned and maintained. It is also recommended to consider the environment you will be working in when choosing an evaporator. Some are built to withstand harsh conditions, while others can be used in moderate conditions. Also, you’ll want to make sure your evaporator is covered by a solid guarantee that will safeguard your investment.

Fan

The blower fan of your HVAC system circulates cold or hot air throughout your home until you reach the thermostat setting. The fan can either be set to auto or constant. We suggest keeping the fan on at all times for maximum efficiency and to cut down on electricity bills. We could replace the fan motor in the event that it is continuously running. The new ECM motor is up to 70 percent more efficient than the old PSC motors. It will pay for itself over the lifetime of the unit.

If your fan is only running on high, an unbalanced circuit or a broken relay could be keeping your thermostat from adjusting to the fan.

Filter

The filter is used to circulate the air in the home before it is heated or cooled. It removes impurities and also stops dust and pet dander getting into the system and contaminating internal components. It also shields family members from the spread of diseases by tiny pathogens that are floating in the air. It also ensures that the system works efficiently. A dirty filter can make the system work harder and could cause it overheat or breakdown.

Homeowners should replace their filters frequently at least every 30 or 90 days, based on the label instructions. If a homeowner isn’t certain what kind of filter they need they should talk to an HVAC professional. A professional can help homeowners select the best filter for their home, in light of factors like temperature, how often they use their system, and even personal factors such as whether there are 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 typically situated on the wall, ceiling or floor, or in the utility closet. It usually has a large metal grille that protects the filters. The filter should be easily accessible for homeowners and service technicians to facilitate cleaning and replacement.

Filters are rated according to their MERV rating (Minimum Effectiveness Reporting Value) which reveals how well they capture various sizes of particles. A filter with a low MERV can filter larger particles such as dust mites or pet dander but not fine allergens or germs. High-MERV filters can snag many kinds of contaminants without affecting the normal flow of air.
