Whether you want to stay cool in the summer or warm in the winter, your home’s heating, ventilation, and air conditioning (HVAC) system keeps you comfortable year-round. Unfortunately, there are times when your system could run into problems. Here are some of the most common HVAC issues many homeowners face.

Dirty or Clogged Filters

Proper airflow is essential for your HVAC system to operate at optimal efficiency. A filter clogged with dust, dirt, pet hair, or other debris can inhibit airflow through your air conditioner or heater, causing a host of issues.

For instance, dirty filters can cause your heating and cooling system to work harder than it is supposed to, causing unnecessary wear and tear. They can also lead to issues like hot and cold spots, a frozen AC unit, and higher-than-expected utility bills.

Experts suggest that you change HVAC filters at least every three months. However, you may have to change yours more often due to factors like whether you have pets or how many people live in your home. Many homeowners inspect their filters once a month to ensure they replace them when necessary. A clean air filter ensures your heating or cooling system runs as it should and also helps maintain indoor air quality.

Thermosate Calibration Issues

Another common problem is that your thermostat is not reading the ambient temperature in your home correctly. If this is the case, you may be experiencing inconsistent heating and cooling.

A simple way to test your thermostat is to tape a reliable thermometer to the wall beside it. Wait about 15 minutes, and then compare the two readings. If the temperatures are not within a few degrees of each other, you will need the help of an HVAC technician to calibrate it.

Tripped Circuit Breakers

Tripped circuit breakers are another common issue homeowners have to deal with. If your heating or cooling system suddenly stops working, checking your electric panel should be your first step in identifying the problem.

A breaker can trip for external reasons related to multiple power fluctuations. You can reset the breaker by flipping the switch to the “off” position and then back to the “on” position. After that, your HVAC unit should return to normal operation.

However, if the system continues to trip the circuit, it will be time to contact a technician. You might have an issue with faulty wiring or other electrical problems within your home. A professional can check if the circuit your HVAC system is on is overloaded or if there is another problem within your electrical system.

Refrigerant Leaks

Refrigerant cools the warm air in your home as it passes through your air conditioner’s or heat pump’s coils. Low levels of this fluid can affect cooling performance. Often, these leaks are the result of loose connections or damaged coils. A trained HVAC professional should handle this problem. They will inspect the unit, repair the leaks, and recharge the system with the correct refrigerant.

Unusual Noises

When an HVAC unit clicks on, it is common to hear a slight hum or buzz. However, if you hear any loud grinding, squealing, or rattling, it could indicate a problem.

Many times, these noises are signs that there are loose components or worn-out parts in your system. You might have a worn bearing, a failing motor, or a loose fan belt. These issues will gradually become worse over time, and you could be left without a functioning unit. Calling a professional right away is essential to avoid an expensive emergency breakdown.

Blocked or Closed Vents

Each room in your home has a return and supply vent. They ensure proper airflow through your heating and cooling system and are essential for even temperature control.

Household items like furniture, area rugs, and drapes can block these vents. To ensure proper airflow, they should have a clearance of at least 6 to 12 inches around them. You should also check that they are in the open position.
