Top 5 Things To Know About Your HVAC System

Your HVAC system can be your best friend in the sweltering summers and frigid winters, keeping you and your family comfortable and safe all year long. But what would your HVAC system have to say if it could talk? Of course, your HVAC system can’t speak, but it has ways of letting you know when it needs attention. Let’s take a look at some of the things your HVAC system might want to tell you in order to maintain optimal performance throughout the year.

1. Insufficient airflow


If your air conditioner isn’t cooling properly or the airflow isn’t as strong as it should be, your HVAC system may tell you that the ducts or vents are clogged. Fortunately, this is a problem that can often be easily fixed. Filters are a good place to start. When filters are dirty, air cannot flow properly through your system and cool the air in your home.

Filters are located either in your indoor units or behind the grille in the hallway if you have a ducted system. They need to be changed regularly to keep the air clean and the flow smooth. It is also important to keep the outdoor condenser clean and free of debris to ensure good airflow. You can remove debris from all sides of the condenser with a garden hose after you shut down the system.

2. Strange noises and odors

If your HVAC system is making grinding or rubbing noises, it may be time to replace it or at least give it a thorough examination. Strange sounds mean there is a serious problem with the system. Be sure to contact a technician if your HVAC system is noisy.

Strange odors are also a sign that something is wrong. Mold can build up in an HVAC system and cause health problems for your family. Unusual odors can also mean that there is a wiring problem in the system that could be dangerous. Be aware of strange noises and odors coming from your system.

3. Air circulation without cooled air


If the air is flowing smoothly but not cold, your system may tell you that the compressor is at the end of its life. A low refrigerant level may also be the cause. A refrigerant leak can be a dangerous problem. It is, therefore best to have your system checked as soon as possible when you notice a drop in cooling performance.

4. Frost in summer

Frost on the pipes of your HVAC system indicates that it is frozen, which hinders the cooling capacity of the system because the refrigerant cannot circulate properly. The system can be thawed temporarily by leaving the fan on while the air conditioning is off. If the system freezes again, there may be a serious problem, and maintenance or retrofitting may be required.

Ultimately, the problem could be something as simple as a dirty filter or clogged ducts. Again, checking the filter and the system’s ducts is a good place to start. If this doesn’t solve the problem, it’s time to bring in a specialist to take a look.

5. Moisture and leaks

If you find water or moisture around the components of your HVAC system, your system is telling you that it has a leak. It could simply be a clogged or leaking condensate pump that needs to be changed or repaired. Moisture around the system components will eventually lead to mould growth. There may also be a refrigerant leak that could be dangerous to people in the house. Maintenance or repairs should be carried out at the first sign of a leak to avoid more serious problems in the near future.

If you listen carefully, you will find that your HVAC system has a lot to say. Paying close attention to the system is the best way to stay safe and comfortable while avoiding higher costs later. When your HVAC system talks, remember to listen!
