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 is powered by propane, oil or natural gas to create heat for the furnace, while electricity powers the cooling components in an all-electric unit.

Vents (or registers) are located in the ceiling, wall or floor of every room. You should keep them open as much as you can to ensure that air circulation is maintained 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 turns on the exchanger to draw fresh air from outside your home, and to vent old air through your ductwork.

The majority of thermostats are digital although some older models still exist. Digital thermostats utilize a device called a thermistor, which has metals that change electrical resistance when changes in temperature. The thermistor is connected to an microcontroller that converts changing resistance into a temperature reading. There are a variety of thermostats, including smart and programable thermostats. They allow you to control and adjust your home’s power consumption.

Thermostats are located on the interior walls of your house, typically in rooms where they are used the most. The place of your thermostat will affect its accuracy. A thermostat located in direct sunlight, for example, may show more heat than the actual temperature of the room. This could cause your system to run more or less. If your thermostat isn’t operating correctly, try reset it but if that doesn’t fix the problem then you should contact an AC technician for help.

If you’re thinking about changing your thermostat, you should check out the various options available to you and consider the possibility of a programmable thermostat to reduce your energy costs. A thermostat that is programmable will automatically adjust the temperature of your home according to your schedule rather than requiring you to manually manipulate your HVAC system each day. You should also find out if there’s a more efficient model, such as one that is ENERGY Energy Star certified or energy efficient.

Condenser

Condensers are typically the culprit when your air conditioner isn’t functioning properly. The condenser consists of a number of parts that have to cooperate to function. The entire system could be affected when any of these components are damaged or worn out. Problems with the condenser include a malfunctioning control board for the condenser or leaks of refrigerant.

The compressor pushes the refrigerant into the condenser where a fan blows cooled outside air over the coils. This allows the refrigerant gas cooling and to return to a liquid state. This low-pressure liquid is then removed and cooled before being returned to the evaporator to continue cooling. The process repeats to achieve the temperature you desire for your office or home.

The most important thing you can do to ensure that your condenser working correctly is to ensure that the area around it remains free of any debris. The condenser’s fan can pull leaves, twigs and other debris into the unit, creating obstructions and hindering the cooling system from working effectively. It’s important to keep trees and bushes trimmed so that they don’t encroach on the unit. This will reduce the possibility that branches, berries or nuts will fall and clog the system. Clean your condenser to prolong the lifespan of your AC by a minimum of 1-2 years.

Evaporator

The evaporator is the thing that moves warm air in your home. It is made up of a series of tubing which is u-shaped and set into panels. The coils are being blown by the air of the blower. This is a way of transferring heat from the indoor atmosphere 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 that heat moves from colder to hot objects. If the evaporator operates correctly, the energy is transferred from warm air to the refrigerant that is colder. This causes the refrigerant’s water to boil or evaporate into gas. In this process, heat that is not measured using thermometers, referred to as latent heat is transferred from air to the refrigerant.

These coils are constructed with special structures that enhance the transfer of heat. These are known as fins, and they increase the surface area to aid in the transfer of heat. Copper and aluminum are both used to make evaporators, each with distinct advantages.

A evaporator with an accumulation of organic growth is prone to issues. This is usually caused by mildew or even mold. If this happens, the bacteria will produce a smell that spreads throughout the house. This may cause discomfort.

To avoid these issues, it is important to choose an evaporator that is easily cleaned and maintained. When selecting an evaporator it is essential to think about the working environment. Certain models are designed to withstand harsh conditions, while others are suited to moderate environments. It is also important to ensure that your evaporator is protected by a warranty that will protect you and your investment.

Fan

The fan that blows air in your HVAC system circulates hot or cold air in your home until you get to the temperature you want. The fan can be set to auto or constant. We suggest keeping the fan running on a constant basis to maximize efficiency and reduce your electricity bills. We could replace the fan motor when it is running continuously. The new ECM motor is up to 70% more energy efficient than the older PSC motors. It pays for itself over the life of the unit.

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

Filter

The air passes through the filter before it is warmed or cooled and circulated throughout the home. It eliminates impurities and prevents dust and pet dander getting into the system and contaminating internal components. It also shields family members from illnesses spread by tiny pathogens floating in the air. It also ensures that the system functions efficiently. A dirty filter makes the system work harder and could cause it overheat or to fail.

Homeowners should replace their filters frequently at least every 30 or 90 days, based on the instructions on the label. A homeowner should consult a HVAC professional if they are unsure of the type of filter they require. A professional can help homeowners select the best filter for their home, in light of factors like the climate, the frequency they use their system, and even personal factors, for instance, whether there are allergy or smokers sufferers 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 could be found on the wall, floor, ceiling, or storage closets, and it usually has a large, metal grate which covers the filter. The filter should be easily accessible to both technicians and homeowners to make it easy to clean and replace.

Filters are rated based on their MERV rating (Minimum Effectiveness Reporting Value) which indicates how well they are able to capture various sizes of particles. A low-MERV is able filter larger particles such as dust mites and pet dander but not fine allergens or germs. High-MERV filters can snag many kinds of contaminants, but it doesn’t affect the flow of air.
