The Heating, Ventilation, and Air Conditioning system or HVAC system plays an important role in every building. It consists of different parts like refrigerant, ductwork, air handlers, fans, valves, etc. These systems help in maintaining indoor temperature and humidity levels. In this article, we will discuss about HVAC system and the types of HVAC repair and services.
What is HVAC?
HVAC stands for heating ventilation air conditioning. These systems help in cooling down the room during the summer season and heating up the room during the winter season. It does this by circulating indoor air into different parts of the house and outside. It also keeps the humidity level constant inside your home.
Basic components of HVAC systems
The heating, ventilation, and air conditioning or HVAC systems help keep our homes comfortable. They use energy to heat or cool the air inside buildings.
An HVAC system components include mixed-air plenum and exhaust fans, ductwork, terminal devices, return air systems, etc.
- Heaters and coolers are usually self-contained units that include a blower, heat exchanger, thermostat, humidifier/dehumidifier, controls, and other accessories.
- A water chiller is basically a refrigeration device that uses water as a working fluid.
- Air handlers (also called fan coil or variable speed) is the main component in most HVAC systems. They distribute conditioned air throughout the building through ducts.
- Ductwork refers to the pipes used for conveying conditioned air from the air handler to the various areas of the house.
- Exhaust fans are used to move indoor air into the outdoor environment.
- Return air systems provide fresh air back into the home after it has been circulated by the system.
- The evaporator coil inside a cooling unit transfers heat from the circulating refrigerant to the surrounding air, which causes the temperature of the air to drop.
- Heat pumps use electricity to transfer heat between two different locations.
- Humidifiers add moisture to the air and dehumidifiers remove moisture from the air.
- Programmable thermostats allow you to set the temperature at certain times during the day and help you save on heating costs.
Types of HVAC Services that an HVAC Service Technician Provides
Your home heating and cooling system play a key role in making sure your family stays comfortable throughout the seasons. However, it requires constant care and attention to keep working properly.
There are many different types of HVAC services that an HVAC professional provides to maintain your HVAC system. Most HVAC field service technicians specialize in routine maintenance, repairs, and installations.
Some HVAC technicians provide consultation on how to save money on energy bills and tips on improving the air quality of your home.
An HVAC maintenance technician provides the following types of services:
1. HVAC Repair
This type of repair involves fixing any problem with your air conditioning systems and HVAC system. It may involve changing out the compressor, evaporator, condenser, blower, or other components.
A broken or dirty evaporator coil causes your unit to work harder. Replacing the coil will help improve efficiency. Blower motors are responsible for moving air through your vents. If they stop working, you’ll need to replace them. Filters trap dirt and debris so that it doesn’t get into your air. Filters need to be changed regularly. Condensate pans collect water that drips off your coils during operation. When these pans become full, the HVAC field service technician empties them.
2. Heating Service
Heating service is performed for heating equipment like furnaces, boilers, heat pumps, and radiant heat systems. The most common heating service is furnace tune-up which includes an HVAC field service technician inspecting the combustion chamber, burner, filter, and gas valve.
3. Furnace Tune-Up
Furnace tune-ups are usually scheduled once every three years by HVAC field service companies. They typically include a visual inspection of the furnace, including the burners, flue, and chimney.
4. Duct Cleaning
Your drain lines carry away moisture and waste products from your home. These lines can become blocked over time. The HVAC maintenance technician cleans the duct by removing dust and debris from the air ducts. It also removes mould spores and bacteria.
5. AC Maintenance Services
It is similar to furnace maintenance but focuses on cooling units like AC units and refrigerators.
6. Heat Pump Service
Heat pump service is similar to furnace maintenance except that it deals with heating instead of cooling.
7. Refrigeration System Service
Refrigeration system service is similar to furnace service except that it deals with cooling rather than heating.
8. Plumbing Service
Plumbing service is performed by an HVAC maintenance technician for pipes, drains, faucets, toilets, and urinals. This type of service is often needed if you notice leaks or clogs.
9. Electrical Service
Electrical service is performed for electrical wiring, outlets, switches, light fixtures, and appliances. This type of service can be required if there is an issue with your lights, appliances, or electronics.
10. Window screen & Insulation replacement
Window screens keep insects out of your house. Over time, window screens can break down and require replacement. Insulated windows and doors reduce energy loss. If insulation becomes damaged, it may need to be replaced.
11. Preventative Maintenance Services
You need regular HVAC maintenance to ensure the longevity and safety of HVAC systems. Most homeowners don’t realize just how much work goes into keeping their HVAC units running smoothly.
The best way to avoid costly repairs down the road is to schedule regular preventative maintenance checks with an HVAC field service company. The HVAC maintenance technician would periodically check filters, coils, fans, thermostats, and air ducts.
The Benefits of HVAC Services
Benefits of regular HVAC maintenance and HVAC field service include :
1. Safety
Regular inspections will help detect problems in your HVAC systems and equipment before they become serious issues.
2. Energy Savings
A well-maintained system will run more efficiently and last longer than one that isn’t maintained regularly.
3. Comfort
An efficient HVAC system helps keep your home cool and comfortable all year round.
4. Health
Air pollution is a major cause of respiratory illness. A clean indoor environment reduces exposure to harmful particles and gases. When your system works correctly, it prevents pests from entering your home.
5. Value
Having a well-functioning HVAC unit means no more cold rooms or hot rooms! Regular maintenance of your HVAC system by a professional HVAC technician means you won’t have to spend extra money replacing it when it breaks down. By scheduling regular HVAC maintenance, you’re saving yourself time and money.
Conclusion
HVAC services are necessary to maintain your comfort level inside your home. They also save you money by preventing expensive repair bills. It’s important to choose a reputable HVAC customer service company that assigns a skilled HVAC technician with good experience installing, repairing, maintaining, and cleaning the HVAC system.
