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 of an electric HVAC unit uses propane, oil, or natural gas to heat the furnace.

Every room is equipped with vents (or registers). They are situated on the ceiling, walls or floors. If possible keep them open to ensure air flows properly throughout your home.

Thermostat

The thermostat is a crucial component of your HVAC system. It regulates the temperature in your home by switching off and on the compressor and fan until they achieve a specific temperature, and it also activates the air exchanger to pull fresh, outside air into your home, while venting old, indoor air through your ductwork.

Most thermostats are digital, although some older models still exist. Digital thermostats are controlled by a thermostat. This device has metals which change resistance as temperatures change. The thermistor is connected to a controller converts the resistance change into temperature. There are various kinds of thermostats that include smart and programmable thermostats. These allow you to control and alter your home’s energy consumption.

Thermostats are located on the walls of your house, typically in rooms that are used the most. The location of a thermostat in your home could affect its accuracy. A thermostat placed in direct sunlight, for instance it could display more heat than the actual room temperature. This can cause your system to operate more or less. If your thermostat isn’t working correctly, try setting it again, but if this does not solve the issue it is recommended to contact an AC technician for assistance.

You should consider a programmable thermostat if you are replacing your existing thermostat. You will reduce your energy costs. 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 on a daily basis. It is also advisable to see if there is an efficient model, like one that’s ENERGY A STAR-certified or energy-efficient.

Condenser

Condensers are usually the cause when your air conditioner isn’t performing in the way it should. The condenser is comprised of several parts that must work together to function. If any of these parts become damaged or wear out, the whole system can be impacted. The most common problems found in the condenser are a broken control board or refrigerant leaks.

The compressor pushes the refrigerant into the condenser which is where a fan blows cooled outside air over the coils. This allows the refrigerant to get cool and transform to a liquid state. This cooled low-pressure liquid then 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 ensure that your condenser operating effectively is to ensure that the area around it remains clear of debris. Leaves, twigs, flowers grass and other debris may be sucked into the unit by the condenser fan. This can cause clogs that prevent proper operation of the cooling system. It’s also a good idea to keep the trees and shrubs trimmed so they don’t encroach onto the unit. This reduces the likelihood that berries, nuts, or branches can fall into the system and clog it. The condenser that is free of debris can add 1-2 additional years to the life of your AC system.

Evaporator

The evaporator is the thing that circulates warm air inside your home. It is made of a series of tubing which is shaped like a U and then set into panels. Air from the blower fans is blown over these coils. This draws heat from the indoor air and then transfers it to the refrigerant. The refrigerant’s liquid is converted into a gas, then circulated throughout the cooling system to cool your indoor air.

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

These coils have been designed with specialized shapes that enhance heat transfer. These are known as fins, and they expand the surface area to facilitate the transfer of heat. Aluminum and copper are both used to build some evaporators, each having their own advantages.

One of the most frequent issues with an evaporator is the accumulation of organic growth. This can be a result of mildew or mold. If this is the case, the sour smells caused by the bacteria can be absorbed by the house and could cause discomfort.

It is important to select an evaporator that can be easily maintained and cleaned. When choosing an evaporator, it is essential to take into consideration the environment in which it will be operating. Certain models are designed to withstand harsh environments, whereas others can work well in moderate environments. In the end, you’ll want to ensure that your evaporator has a solid warranty that will ensure your investment.

Fan

The fan that blows air in your HVAC system circulates hot or cold air throughout your home until you reach the temperature setting. The fan can be set to auto or constant. We recommend that you keep the fan running continuously to maximize efficiency and save money on your electricity bill. We could replace the fan motor in the event that it is continuously running. The new ECM motor is 70% more energy efficient than the previous PSC motors. It is able to pay for itself over the life of the unit.

If your fan is only operating at the high setting, a broken relay switch or short circuit could be blocking the settings you set on the thermostat from reaching the fan.

Filter

The filter is used to circulate the air in the home before it is heated or cooled. It eliminates impurities and prevents dust and pet dander getting into the system and contaminating internal components. It safeguards the family from illness spread by airborne pathogens. It also ensures the system is operating efficiently. A dirty filter can cause the system to perform more efficiently, which could cause it to overheat and ultimately break down.

The homeowner should change their filters on a regular basis – every 30 or 90 days, based on the directions on the label. A homeowner should seek advice from an HVAC professional if they are unsure about the kind of filter they need. A professional can help homeowners select the best filter for their home, depending on factors such as temperature, how often they use their system and even personal factors, for instance, whether there are allergy sufferers living in the home.

The filter is located in the return air duct or in certain cases, the blower compartment, of the furnace. The return air duct may be located on the wall, floor or ceiling, or in a storage closets, and it often contains a large metal grate that is covered by the filter. Ideally, the filter is accessible to homeowners and service technicians to aid in cleaning and replacement.

Filters are evaluated based on the MERV (Minimum Efficiency Reporting Value) rating, which indicates how effective they are in collecting different sizes of particles. A low-MERV is able filter larger particles such as pet dander or dust mites but not fine allergens or germs. High-MERV filters, on contrary, can capture a wide range of contaminants without limiting normal airflow.
