Being a homeowner entails several duties and responsibilities that you need to perform to have a comfortable dwelling at home.

Before calling a trained technician for its HVAC service, it is always best to understand first how an HVAC system works, common HVAC problems, HVAC maintenance tips, and other things you need to know about the HVAC system.

WHAT IS AN HVAC SYSTEM?
The word HVAC stands for heating, ventilation, and air conditioning. HVAC systems provide environmental comfort for the people who live in the place. HVAC systems can be found both in the residential and commercial buildings. The system does not just provide heating or cooling temperature but also improves the indoor air quality through proper ventilation.

HOW DOES IT WORK?
As we know, the HVAC service system has three main functions for improving indoor air quality and providing thermal comfort. Its system comprises complex parts such as air return, exhaust outlets, filter, ducts, outdoor unit, electrical elements, coils, compressor, and blower.

MOST COMMON HVAC PROBLEMS
Since the HVAC system includes complex parts, there are lots of issues that the system can encounter. While some of the HVAC problems can be fixed by simply cleaning coils and filters, these issues might worsen if no HVAC repair isn’t madeimmediately. Here are some of the HVAC problems to watch out for when doing maintenance work.
- Leaks. The HVAC system is connected through drain lines, which is prone to leaking. So, if you noticed that your house isn't warming or cooling enough the way it should be, leaks might be the culprit. The HVAC system becomes less efficient because the cold or hot air is being discharged through the leaks. As a result, the system will work harder to achieve the set temperature. You also have to keep an eye on the unit's refrigerant level. You will know if the refrigerant level is low, if there's ice building up on the copper lines connected to the AC, has condensation water around the furnace, and if your electrical bill skyrocketed.
- Dirty Filter. Part of the HVAC system is its air conditioning unit, and one of the most common issues with the AC unit is a dirty filter. AC may be prone to dirty filters since it cleans the indoor air in your house. And when the filter is clogged with dirt and debris, air won't flow easily, which can cause less efficiency of the HVAC system.
- Clogged drain. If the drainage becomes clogged, it will greatly affect the performance of the HVAC system. Although most of the HVAC units now have the sensors to alert you whenever the AC drain is clogged, one way to determine it is if the drain pan is full of water. It is critical to fix this issue as soon as possible since it can cause water to back up and damage your home.
- Corrosion. Moisture in the electrical wirings inside the HVAC system can cause corrosion. And once it happens, it might result in unusual off and on, forcing your system to work harder that will lead to total shutdown over time.
- Faulty thermostat. The thermostat serves as the control system of your HVAC system. That's why if the thermostat is not working the way it should be, contact your technician to calibrate the thermostat. Try also to upgrade to a smart thermostat to provide convenience in controlling your HVAC system.

TIPS IN MAINTAINING YOUR HVAC SYSTEM
Proper and regular maintenance on the HVAC system will reduce the chance of costly breakdowns by as much as 95% and will let you save money on the energy bill of up to 30%. Therefore, HVAC maintenance is essential in keeping your unit in tip-top shape. Although you can enter into a contract with a licensed technician to regularly maintain your HVAC repair system, it doesn't mean that you cannot do some maintenance tasks on your own.

Here the maintenance tips that you can follow, depending on the given timeframe.

Now
- Inspect your outdoor and indoor units if there is visible debris around, such as grass, leaves, boxes, and furniture.
- Ensure to have at least two feet clearance around all HVAC components.
- Buy a high-efficiency air filter for your HVAC system so that you can use it to change filters whenever necessary.

Once a month
- Look for any possible leaks in your AC refrigerant lines to avoid further damage to your house.

Once a season
- Change air filters every three months, as most expert technicians suggest to you during the HVAC maintenance.
- Try to turn off the water to the furnace humidifier during summer.
- Replace the humidifier filter and turn the water back during the fall.

Once a year
- Do not forget to change the batteries on every carbon monoxide detector inside your house.
- Add lubrication to the HVAC motor and check the fan belt if it is running efficiently. If not, try to replace it with a new one.
- Clean your AC condensation drain line using bleach.
- Inspect your outdoor AC unit and make sure that the unit is standing on a ground-level aside free from debris and blockage.

SIGNS THAT YOU NEED TO REPLACE YOUR HVAC SYSTEM
An HVAC system's usual lifespan is 15 to 25 years, but with proper and regular maintenance, it may prolong its life expectancy.
However, just with any equipment, many parts of the HVAC system are subject to wear and tear. To prevent your HVAC system from a total shutdown, call a trained technician to fix the issue before getting worse. Here are some signs that some parts of your HVAC system need replacement.
- It only blows out warm air.
- It turns off and on intermittently.
- You notice some imbalance in air temperature across the house.
- It produces odd and strange noises.
- The energy bill is unexplainably high compared to your previous energy bill consumption.
- It produces poor airflow.
