You should look out for three areas to see whether your HVAC unit is performing to its full potential and the HVAC is working efficiently or not, these areas are:
Your HVAC unit will continue to function if you ensure some preventive measures regularly. These preventive tasks are simple, and you do not require any technical skills to manage such actions. If you ensure these preventative operations not only it will keep your HVAC function, but it would also increase the longevity of your appliances.
Replacing the Air Filters
Your HVAC unit works at all times so you should make it a routine to change the air filters after every 3 to 4 months. If you do not change the filters the dust, hair and other particles will choke the screens, and it will disrupt the operations of the system. If you have pets in your accommodation, it adds up to the need for changing the air filters. Some big HVAC units or powerful system may not need a change in air filter for a long time; however, you need to discuss this with the provider to ensure you do not stall any necessary filter replacement.
Manage the Right Temperature on your Thermostat
Another important detail you should check is setting the right temperature in your thermostat. This setting will not only add to the functioning of the HVAC unit but will also help you bring down your utility bills. Many people are having a misconception that by increasing or lowering the temperature considerably at one go, they will be able to heat up or cool the place quickly. In reality, it takes the same time, and you end up pushing your system way harder than needed. You need to set the thermostat at an average temperature and give it some time to place in the temperatures you require.
Outside Unit Cleaning
Keep a regular check on the outside unit and clean it regularly. Sometimes the dust that settles on the outdoor unit prevent the airflow or block it, causing the HVAC unit to malfunction or work in continuous external pressure. You can take a garden hose and clean the outside unit of the HVAC. Make sure all power connection are off and shut down during the cleaning.
Inspect and Control the ductwork
Check if there are any holes and space in the ductwork that causes the air to leaks through them. Check if there is any release of cold air and what options you have to fix the holes. Generally, flexible ductwork requires complete replacement whereas the metal ductwork can take some repairs, like sealing and closing the gaps by using duct tape. In high temperatures the risk of cracks in ductworks are more so you can use additional insulation wrapping with a foil reinforcement to shield the ductwork from high temperatures, so it operates longer without any breaks.
Regular inspection will enable you to keep a check on the performance of your HVAC unit and to identify any areas that you need to work on to increase the efficiency of your HVAC unit. Some of the essential aspects you should look into when checking the HVAC system includes:
Inspecting the Air Ducts
Check the air ducts regularly to ensure that there are no cracks, hole or dirt in them that can block the openings. Cleaning the duct system is simple; however, if you are not too sure how to do it, you can always seek the help of a qualified technician for the cleaning operations.
Inspect your Thermostat
Check the performance on your existing thermostat. You may not have this system in the older unit, and the best thing you can do is to make some expense in purchasing a programmable thermostat that will allow you to control the temperature throughout the day as you need. If you are away from home for long hours, you can save a considerable amount just by using and controlling the temperature by a thermostat.
Monitor Temperatures in all Rooms
If you feel that your temperatures are uneven in the different rooms, this is an indication of the air not flowing evenly in all places. It is better to bring in a qualified technician to check the complete unit to ensure there are no faults and malfunctions in your HVAC appliances.
Keep a Look on the Calendar
Although it is simple to keep a check on time, people often ignore this crucial detail. You should know the number of years you have your HVAC system in place, to ascertain its strength, working life and need for replacement. Generally, any unit that you have for over ten years should be taken off, and you should replace it with a new one. Older HVAC units are not only less functional, but they also impose health and environmental hazards and will consume more energy.
You can do a simple test to check the efficiency of the cooling unit. This test is for the older systems as the new ones have built-in functions where you can review the performance by just clicking on a few buttons.
You will need to get a regular room thermometer of the traditional digital meat thermometer that you use in your kitchen. Make sure that your air conditioning is working for at least thirty minutes before you start the test. Directly check the temperatures by comparing the air that is coming out of the vent to the air temperature going back.
You can get a steady readout by placing the thermometer in the airstream near to the supply register that is close to the inside cooling system and set it there for three to five minutes. Repeat the same procedure for the return vent.
Analyze both temperatures. Ideally, the air coming out should be fifteen to twenty degrees cooler when compared to the air inflow.
If you observe abnormal temperatures by doing a few tests, it can indicate a problem in the refrigeration unit or can imply that the system has lower refrigerant and need expert maintenance.
You should ensure regular maintenance of your HVAC unit to ensure smooth performance during peak season. Follow the guidelines, and it will help you to keep your HVAC units in order and give you the best performance throughout the year.
