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 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 on the floor of each room. If you can, keep them open to ensure that air circulation is properly distributed throughout your home.

Thermostat

A thermostat is among the most vital components of your HVAC system. It regulates your home’s temperature by turning on and off the compressor and fan to attain a certain temperature. It also switches on the air exchanger to bring fresh air from outside into your home, while venting old, indoor air through your ductwork.

Most thermostats are digital, although older models do exist. Digital thermostats are controlled by the thermosistor. The device contains metals that alter resistance as temperature changes. The thermistor is connected to a controller, converts the resistance change into a temperature. There are a variety of thermostats that include smart and programmed thermostats. They allow you to monitor and alter your home’s energy consumption.

Thermostats are placed on the interior walls of your home, typically in rooms where they are used most often. The location of your thermostat can affect its accuracy. For instance one thermostat placed in direct sunlight could appear hotter than the actual room temperature, causing your system to run too much or not even run at all. If your thermostat isn’t functioning correctly, try resetting your device. If this doesn’t work then contact an AC technician.

If you’re considering replacing your thermostat, be sure to check out the various options available for you, and consider the possibility of a programmable thermostat to reduce your energy bills. A thermostat that can be programmed will automatically adjust the temperature of your home to your schedule, instead of requiring you to manually manipulate your HVAC system on a daily basis. It’s also worth a look to determine if you can locate a better model that can offer you even more energy savings, like an energy-efficient or ENERGY certified thermostat.

Condenser

Condensers are typically the culprit when your air conditioner isn’t performing as well as it should. The condenser consists of several components that cooperate to function. If any of these parts get damaged or worn out, the whole system can be impacted. Condenser issues can include a damaged condenser control board or leaks of refrigerant.

The refrigerant gas produced by the compressor is pushed into the condenser, where fans blow cool outside air over the coils. This helps the refrigerant get cool and transform into a liquid state. The low-pressure liquid that has been cooled is redirected back to the evaporator to continue the cooling process. The process is repeated until it reaches the desired temperature for your home or office.

The most important thing you can do to ensure that your condenser running effectively is to ensure that the area around it is free of debris. The condenser’s fans can pull leaves, twigs and other debris into the unit, creating obstructions and preventing the cooling system from working efficiently. It’s important to keep the bushes and trees trimmed so that they don’t cause obstruction on the unit. This can reduce the chance that branches, berries, or nuts could fall on the system and cause a blockage. Keep your condenser clean to extend the lifespan of your AC by a couple of years.

Evaporator

The evaporator is the part that moves warm air into your home. It is made of a series of tubes that are set into panels. Air from the blower fan is blown across these coils. This transfers heat from the indoor atmosphere to the refrigerant. The refrigerant’s liquid is converted into a gas and circulated throughout the cooling system to cool your indoor air.

The law of thermodynamics states heat moves from warmer to colder objects. If the evaporator is operating correctly, the heat energy is transferred from the warm refrigerant to the cold air. The refrigerant gas causes to vaporize or boil. During this process, the heat that cannot be measured by thermometers, referred to as latent heat is transferred from the air to the refrigerant.

The coils are designed with special shapes that aid in heat transfer. Fins are utilized to increase the surface area of coils. Certain evaporators are constructed with copper, while others are made of aluminum, with each material providing its own set advantages.

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

It is important to select an evaporator which can be easily maintained and cleaned. It is also an ideal idea to take into consideration the working environment when selecting an evaporator. Some are built to withstand harsh conditions, while others can be used in moderate conditions. In the end, you’ll want to make sure your evaporator has a solid guarantee that will protect your investment.

Fan

The fan in your HVAC system circulates cold or hot air throughout your home until you reach the thermostat setting. The fan can be set to auto or constant. We recommend keeping the fan running at all times for maximum efficiency and to cut down on electricity bills. If your system’s fan is continuously running we can replace it with an ECM blower motor which is up to 70 percent more efficient than the old PSC motors and pays for itself in savings over the duration of the unit.

If your fan only operates on high, a short circuit or a broken relay could be keeping your thermostat from adjusting to the fan.

Filter

Air flows through the filter before it is warmed or cooled, and then circulated around the house. It eliminates impurities and prevents dust and pet dander from entering the system and contaminating the internal components. It also protects family members from the spread of diseases by tiny pathogens floating in the air. It also ensures that the system functions efficiently. A dirty filter causes the system to work harder, which can cause it to overheat and break down.

Homeowners should change their filters on a regular basis. The label will tell them if they should do it every 30 days or every 90 days. A homeowner should consult a HVAC professional in case they are not sure about the kind of filter they require. A professional can assist homeowners choose the right filter for their home, in light of factors like temperature, how often they use their system and even personal factors for instance, whether there are allergy or smokers sufferers 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 usually located on the wall, ceiling, floor or utility closet. It typically has a large grille made of metal that covers the filters. The filter should be accessible to both homeowners and technicians for easy cleaning and replacement.

Filters are evaluated based on the MERV (Minimum Efficiency Reporting Value) rating, which indicates how efficient they are at capturing various sizes of particles. A low-MERV filter is able 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, can capture a wide range of contaminants without limiting normal airflow.
