1. Poor Heating and Cooling Performance
Poor heating and cooling performance can be caused by a few different issues. The air filter may be clogged, the coils may be dirty, the AC unit may be too small for the home, or the thermostat may be set too high. A dirty air filter impedes airflow from the unit and often results in inadequate cooling.
Dirty air coils can prevent the air conditioner from absorbing heat from the air. The AC system may be too small for the home, not effectively cooling all rooms.
2. HVAC Electrical Problems
HVAC electrical problems are a common issue that homeowners often have to deal with. Electrical faults can cause various problems, ranging from poor air flow to high energy bills. Common problems include blown fuses, worn-out capacitors, and corroded circuit boards.
Sometimes, the cause can be a damaged fan motor, electrical wiring, or loose connections. When a problem with electrical comes up, you should consult a professional. They can safely assess the situation and can also offer more electrical services.
3. Clogged Air Filters and Ducts
Clogged air filters and ducts can cause poor airflow, leading to risk of dirt and other particles circulating throughout the air in the home. This can result in respiratory issues for occupants of the house and can cause build up of moisture and bacteria.
Filters should be regularly replaced in order to keep air quality healthy. Additionally, ducts can become blocked from dust, dirt and even pests. Regular inspection and cleaning of the ducts is needed to ensure that air is not restricted from flowing throughout the house.
4. Leak in HVAC Systems
Leaks can occur in the pipes connected to the air conditioner, furnace, or the unit as a whole. The most common culprit is a poorly sealed connection in the pipes where refrigerant gas can escape. AC Refrigerant leaks can also be caused by a faulty or worn-out bladder or valve, a snapped or disconnected pipe, or a hole in the unit.
It is essential to repair any leakage as soon as possible, as the heat gain or loss may cause sudden and drastic temperature changes in the home.
5. Strange Noises and Vibrations
For homeowners, unexpected noise and vibrations can be a cause for concern and can be indicators of potential HVAC issues. Some of the most common causes of weird noises and vibrations can be linked to faulty motors, fan blades, filters, or fans that need to be serviced or replaced.
Unusual noises can also be caused by air blocking the system, or loose parts or furnace bents. In addition, vibrations may indicate damaged piping, ductwork, or other parts of the system.
