Photo By photovs at istock
Since their invention, heating and air conditioning (HVAC) units have increasingly become popular due to the vital role in regulating indoor temperatures regardless of the season. Currently, they account for half of the energy utility bills for homes in Richardson, TX, and other regions.
Not only do HVAC units help in increasing your home’s comfort, but they also maintain a healthy atmosphere by removing allergens such as dust.
Different Types of HVAC Systems
There are various heating and cooling systems that you can choose from to meet your comfort needs.
1. Single package heating and air conditioning system
Just as the name describes itself and a superb choice for homeowners with small houses. It has both the heating and air conditioning components under one cabinet hence limiting the amount of space it covers in any home.
2. Split and ductless split systems
They are simpler in design and functionality than any other HVAC system. They are notably common in most American homes and are positioned inside and outside the house. The only difference is that one is ductless while the other depends on a network of ducts for efficient functionality.
3. Hybrid systems
These are the most recent in the HVAC market. Heating and AC repair and replacement technicians advise homeowners to go for this system since it’s energy-efficient. It regulates indoor temperatures more conveniently than any other HVAC model.
Despite the apparent differences in functionality and energy efficiency between the systems, they all have the same components. Given the importance of these systems in daily living, you should have adequate knowledge of the elements to avoid costly and uncomfortable inconveniences arising from malfunctioning heating and cooling systems.
Thermostats
This component serves as the console or motherboard of any HVAC unit. Easily visible on your home’s wall, the thermostat is used to change the entire HVAC system’s settings, affecting how it warms or cools your house.
Through a readout display screen on the front, the device provides a few details on your indoor temperatures’ current state. This information includes the fan status, the desired temperature you want for your home, the current temperature conditions, and in some instances, the date and time.
Heating and AC repair specialists describe its functionality as follows. It has two buttons with up and down arrows, which can be used accordingly to either raise or lower temperatures. The number that increases or decreases is referred to as the optimal temperature, and it depicts the temperature you want your system to produce.
In this context, if you’re going to increase the temperature, press the upward button to a number you’re comfortable with. The same applies when lowering the temperature. After implementing the settings, all you have to do is sit back and wait for the system to adjust accordingly; you’ll feel the effect in no time.
You can also adjust the fan settings through the thermostat, often denoted by a small fan signal on the display screen. The fan plays a crucial role in regulating indoor temperatures because its outward motion allows it to pump air outside faster.
As a result of constant innovations, newer thermostat models now have automatic settings that homeowners can configure using a timer. For instance, you may set the timer to trigger a desired HVAC unit response 30 minutes before arriving from work. This way, you enter into a pre-warmed or pre-cooled house, depending on your indoor temperature preferences.
Newer thermostat models also have an auto triggering feature that allows the system to automatically detect and adjust the temperature when it has fallen out of sync with the preset.
You can quickly tell when your HVAC or thermostat is in auto mode. The word “auto” will always pop up on the display interface when the cooling and heating effect is taking place automatically. This feature also allows the thermostat to adjust the indoor temperature based on the detected pattern of the homeowner’s preferences.
However, thermostats may begin to malfunction over time. Common thermostat problems include displaying incorrect information, a readout that doesn’t work, and incorrect relaying of temperature adjustments to the entire HVAC system. These are indicators that you need to liaise with heating and AC repair professionals for quick and effective resolution.
Vents
Without the vents, the importance of your HVAC unit becomes obsolete. Vents are the rectangular, metal-slatted outlets responsible for carrying conditioned air into your home’s rooms. Heating and AC repair technicians often install the metallic slats in walls, floors, and the target room’s ceilings.
These features are usually flexible to redirect treated air. The metal used to build these slats is heavily treated to accommodate the drastic temperature fluctuations associated with the HVAC’s heating and cooling processes. This treatment prevents the hot or cold air from going to waste during this final process.
There are two types of vents within your HVAC system, supply, and return vents. Supply vents, as the name suggests, are responsible for the movement of treated air indoors. Compared to return vents, they are smaller in size and have louvers on the grills’ rear side to enhance direct airflow.
To locate the supply vents in your home, you can place a piece of paper atop a vent, and if it’s blown away, you’ve found the supply ventilation apparatus. On the other hand, return vents are more extensive compared to their supply compatriots. They also lack louvers and mainly carry untreated air from your home into the heating and AC unit.
You can conduct the same experiment as that of supply vents to identify where the return vents are in your home. However, return vents are typically denoted by a suction effect.
To ensure that the vents remain free of limber and dust, you can contact a heating and AC repair technician near Richardson, TX, to help you lubricate the vents’ hinges.
The heating and AC repair professionals may also advise you always to ensure that the vents are never blocked. This is because the vents work simultaneously, and a blockage in one upsets the whole system’s balance. They may advise against cutting off the treated air supply to an unused room as this adversely affects the system’s internal pressure, a situation that could lead to costly heating and AC repairs.
Blower Motors
The blower motor is an electric and in-built motor that powers a fan whose work is to push heated air into the system’s ductwork, through the air registers, and ultimately into your home. During the heating and cooling process, combustion typically ends before the motor stops running. As such, the warm air left in the HVAC’s heat exchanger or ductwork will be transported to the rooms before it shuts down as it waits for the next cycle.
Heating and AC repair gurus near Richardson, TX suggest that the blower motor utilizes variable-speed motors. Each variable speed motor is designed to run at a different speed to facilitate more accurate airflow into your home. The variable-speed engines also keep your HVAC system in check and proactively compensate for any problem before it occurs. These motors reach their full speed gradually, a factor that increases their efficiency in lowering indoor temperatures during the summer. This feature also makes them less noisy and more energy-efficient since it helps homes achieve the desired temperature before the speed units reach full speed.
The Furnace
Another vital component of your home’s heating and AC unit is the furnace, which encompasses the heating capacity. Specifically, the furnace is responsible for keeping your home warm as it generates the warmth pumped into your house by the supply vents. To some extent, it could be considered the heart of the heating and AC unit. As such, you must take good care of it to avoid costly inconveniences.
Even though it takes up a great deal of your space, the furnace is more like a sedentary beast. Once tucked away in an ideal position, it may be years before that position is altered. As a concerned homeowner, you can pay it an occasional visit to see if it’s working correctly. However, stay advised that anything inside the furnace is well beyond your reach. Any problem therein should be handled by a trusted heating and AC repair professional.
With this in mind, once you find yourself in the same room as the furnace, take some time to study it. You may notice several tubes located on the exterior side of the furnace. These aluminum ventilation ducts are responsible for pumping hot air produced inside the furnace into your Richardson, TX home. According to heating and AC repair specialists, there are several main types of furnaces. Firstly, there are electric resistance furnaces that typically run on electricity. Their functionality involves blowing air that’s coming in through the return vent overheated electric coils. This air is then pumped forward and into your home by the ventilation apparatus. Electric furnaces heat the air in phases to avoid overusing electricity.
It’s worth noting that malfunctioning electric furnaces not only use too much power, but they can also blow a fuse if left unchecked. However, optimally functioning furnaces monitor and use electric energy efficiently. They have advanced sensor technology that allows them to detect when they’ve used an amount of power that exceeds the circuit’s capacity. As such, heating and AC repair experts recommend them as a suitable option for energy-efficient heating and cooling.
Another popular furnace option is heat pumps. They regulate indoor air temperatures by facilitating the transfer of hot or cold energy from one section to another. Precisely, they heat or cold air that’s closest to their condenser coils, a factor which makes them remarkably similar to HVAC units.
That aside, heating and AC repair professionals can install combustion furnaces, which burn fuel such as propane and natural gas. Their functionality entails the full combustion of an energy source, thereby producing heat transported throughout your home through supply vents. However, these types of furnaces seldom come with air conditioning features.
The Compressor or Condenser Coil
The compressor, otherwise known as the condenser coil, is part of the larger heat exchanger. Heating and AC repair professionals near Richardson, TX, often mount the whole setup outside the house. They also refer to it as the fridge of your home since it’s the component responsible for all the cooling processes. Practically, it achieves this by releasing the heat from inside the house outside.
Specifically, the exchange occurs when warm air, otherwise known as the refrigerant, is compressed into a cold liquid. Afterward, a fan blows over the condenser coils to remove the entire HVAC unit’s heat because of cooling the refrigerant too quickly. When finished, the unit then transports the liquidated refrigerant through aluminum and copper tubes into the evaporator coil.
While here, the refrigerant evaporates into a cold gas, which is then transported to your home, giving you that cooling effect you may desperately need during the summer. These two components work together, and they are the key facilitators of the air conditioning aspect of your home’s HVAC system.
The compressor is quite delicate and requires a great deal of care to be directed towards it. Once every year, you should call heating and AC repair experts near you to clean its components to prevent premature wear and tear correctly. Also, HVAC professionals recommend that homeowners ensure no twigs, leaves, or debris surrounding the compressor. This puts a strain on its performance, which ultimately reflects on the monthly energy utility bill.
Additionally, you should ensure that the HVAC repair professional leaves a few feet of space all around the apparatus to facilitate the maximum flow of air. Heating and AC repair professionals can also set up a shade for the compressor to ensure your unit’s full protection.
