The Common Problems With HVAC Systems
Heating, ventilating, and air conditioning, also known as HVAC, is a technology that is designed for improving the air quality homes and work areas. Depending on the device, it can be used for heating, cooling, or both.
There are several different types of HVAC systems including:
- Single-stage or multi-stage systems
- Zoned systems
- Humidity control
- Heating systems
- Cooling systems
For demonstration purposes,we will describe how split systems work. These devices contain two main parts—indoor and outdoor unit. The inside unit dispenses cool (or hot) air across the room. Split systems use refrigerants to cool down the air. An indoor unit is mounted on the wall in the room that needs to be heated or cooled, and it includes the furnace, evaporating coils, and the blower. The outdoor unit is located outside, in most cases (and preferably) on the same wall as the indoor part of the device. It consists of the compressor, coolant lines, and exhaust fan.
HVAC is also used for cooling or heating the industrial areas, in which case mostly used are packed systems that contain all components of the split systems but within just one unit. These devices are convenient for cooling large areas, and they can be moved according to current needs. HVAC systems are not only used for heating or cooling the air in the room. They are also important for improving the air quality. During the winter time, we tend to keep our windows closed almost all the time. The poor ventilation causes viruses, bacteria, dust particles, and fungi spores to accumulate in the air. That can cause a lot of health problems including dizziness, asthma attacks, nausea, vomiting, cough, throat irritation, and allergy issues. To avoid these problems, it is important to use and properly maintain your air conditioning device.
One of the main reasons why air quality drops over time are dirty filters. This component has to be checked before every cooling or heating season. There are several reasons why filters get clogged including pet hair, your fan is always set to “on”,extremely high or low temperatures that make the fan working overtime, high MERV rating of your filter that enables it to catch even the smallest particles, high levels of dust in the air.
What you can do to solve this problem is to control when the fan is turned on and regularly clean the room and remove the dust from the furniture. Also, maintain your filters according to the manufacturer’s recommendations.
Vents and Ducts
Vents and Ducts can be damaged, resulting in ineffective use of your HVAC system. This can either be a leaky ductor where both the vent and duct are blocked. If the duct is damaged, it will suck in the air from the space where it is going through, such as attic or basement. These issues cannot be managed by a simple DIY project, and they require professional repair.
This may be an underpowered fan or an oversized air conditioning unit. Make sure that the HVAC is suitable for the area you wish to heat or cool. If you are unsure what size of AC fits your needs, contact the professionals. Besides poor air quality, if you purchase the device that is too small for the room,it will not operate efficiently, and if you decide to buy an air conditioner that is too large, you will waste a lot of electrical power and of course, money.
Some of the signs that something is blocking the condenser include noisy operating, poor air quality (bad smell), the device fails to cool the air, and signs of frost on the indoor coil. A blocked condenser can also compromise humidity control mechanism that leads to fungi growth. The good part is that you can fix this issue by yourself. Just make sure there is nothing blocking the airflow, this may include leaves and debris or other covers.
There are two types of coils in the AC unit—evaporator coils that collect heat and humidity, and condenser coils that release the hot air outside. This makes them one of the key components of an air conditioner. Dirty coils mean that your energy costs can go up, your system to have more breakdowns and even shorten the life cycle of the system. They need to be cleaned or maintained at least once a year by a professional.
HVAC systems are important not only for cooling and heating, but also for good air quality as well. For your device to work properly, it should be maintained according to the manufacturer’s recommendations. It includes filter cleaning or replacement, and regular maintenance by a professional. AirRite provides installation, repairing, and maintenance for both commercial and industrial HVAC systems.
