Loose connections are a common cause of HVAC system breakdowns. For example, if a thermostat is not properly connected to the HVAC unit, the unit will not receive the instructions to increase or decrease the temperature. Loose connections are also a problem between the HVAC unit and ductwork. Ductwork is made of metal and can expand and contract with changes in temperature. If the ductwork is not connected properly, it can come loose and cause problems. You can use a multimeter to test for loose connections. A multimeter is a tool that measures electrical voltage, current, and resistance. You can purchase a basic multimeter for less than $100. You can also use a digital multimeter that has a built-in light.
Leaks are a big problem for any type of system, but they are particularly problematic for HVAC systems. Leaks can result in a loss of efficiency and can be very expensive to repair. You can use a blower door test to check for leaks in your HVAC system. A blower door test uses a fan and a large piece of plastic to create a controlled pressure difference between the inside and outside of the house. If there are any leaks, they will cause the pressure to be different on each side of the plastic. A technician will then be able to find and fix the leak. A blower door test can be a bit uncomfortable for occupants of the house, but it is an effective way to find and fix leaks.
HVAC filters trap dirt, dust, and other particles in the air that could be harmful to your health. However, HVAC filters do get dirty over time, and they need to be changed regularly to function properly. Most HVAC systems recommend changing filters once a month. You can check the manufacturer’s instructions to find out how often you need to change the filter. You can also use a filter checker to determine when it is time to change the filter. A filter checker is a small tool that measures the amount of air flowing through the filter and the amount of dirt and dust in the filter. If the filter is dirty, it should be changed immediately.
Damage to the HVAC system can occur over time, and it’s important to check for it regularly. You can use a ruler to measure the blades of your fan and the length of your air ducts. If they are too short, the fan will not be able to properly cool or heat the house. You can also use a HVAC inspection checklist to make sure your system is in good working order.
Maintaining your HVAC system is an important part of owning or renting a property. Even if your HVAC system is working properly and efficiently, it needs attention from time to time. Regular maintenance can help prevent breakdowns, improve efficiency, and save money in the long run by reducing energy bills. It also gives you peace of mind by letting you know your HVAC system is in good working order. If you don’t own or manage a property, you might not think much about your HVAC system until something goes wrong. However, even if you don’t have to deal with these things on a regular basis, you should still be familiar with them. There are some basic things you should know about HVAC systems so you can identify problems before they become major issues.
