As a homeowner or business owner, your HVAC system is critical for comfort. However, it’s easy to run into problems with your HVAC that can leave you feeling overwhelmed and unsure of how best to solve them.

From leaky water lines to weak airflow and inefficient filters, HVAC problems come in all shapes and sizes. Here are some of the most commonly encountered issues and signs to look out for in your HVAC.

1. Leaky Water Lines

An HVAC system’s water lines transport condensation away from the evaporator coils. Over time, these lines can suffer damage due to corrosion, causing them to leak. When this occurs, it leads to wasted water and can cause costly repairs in areas where the water seeps.

Another contributing factor to leaky water lines is clogs. If dirt, debris, or other material clogs your system’s water lines, it can cause them to leak as the pressure builds up. To prevent this problem, schedule preventative maintenance for your HVAC system to keep its components clean and functioning properly.

2. Weak Airflow

If your HVAC system produces weak airflow, it can indicate dirty air filters and blocked vents. Both conditions can restrict the amount of air reaching your system’s components. To address these issues, inspect, clean, and replace any dirty air filters regularly and check all the vents in your property to ensure they are free from debris or blockage.

Another possible cause of weak airflow could be an issue with the blower fan motor within your system. If this component has become worn or damaged over time, it can reduce the airflow coming from your system. In this case, you may need to have the fan motor replaced by a qualified HVAC technician. If you live in Tampa, FL or the surrounding areas, Protek Roofing, Heating, Air & Solar is your go-to company for all your HVAC needs.

3. Inefficient Filters

Filters are crucial components of your HVAC system. They are responsible for trapping airborne pollutants and particles before they enter your property, helping to preserve the air quality. However, if these filters become clogged or worn over time, they can cause airflow issues and reduce the system’s overall efficiency.

For optimal performance of your filters, it is imperative to inspect them and switch out any damaged components routinely. Depending on your system’s filter type, you may need to do this every one to three months. Additionally, clean any reusable filters according to the manufacturer’s instructions.

4. AC Running But Not Cooling

If your AC is running but not cooling your space, there are several potential causes. First, check your thermostat setting and ensure it is not too high for your unit to cool the air effectively. You should also inspect the condenser unit outside your property to see if it’s clogged with debris and clean it if necessary.

Another possible cause could be a refrigerant leak in your system, which can prevent the AC from cooling your home. This issue requires an experienced HVAC technician to fix it.

Lastly, check the fan motor and any wiring connections in your air conditioner to ensure everything is functioning correctly. If none of these solutions work, then it may be time for a repair technician to take a closer look.

5. Burning Smell in the AC

Has your AC smelled funny and then stopped cooling? If this has ever happened to you, it is a potentially dangerous problem. Smelling something burning is a sign of an electrical fire. A faulty wiring connection, a worn or damaged fan motor, or another issue within your AC unit usually causes this.

In this instance, turn off the AC and contact a qualified HVAC repair technician to inspect your system as soon as possible. Doing so will help you avoid any further damage or risk of fire occurring in your home.

6. Unit Randomly Restarts

If your AC unit randomly restarts, it could be a sign of several different issues. First, check the thermostat setting, which can cause your system to cycle frequently if it is too low or too high. In addition, inspect the wiring and other components in the outdoor condenser unit for any signs of damage or loose connections.

Another typical cause of this issue is an old or damaged compressor. If this is the case, you might need to replace it. You should also clean and replace dirty air filters regularly because these can restrict airflow and lead to frequent cycling of your AC unit. If none of these solutions work, it may be necessary to call a qualified HVAC technician to look at the system and diagnose the issue.

7. Freezing of AC Coils

Freezing of the AC coils may occur due to an air filter that is too dirty or clogged, restricting airflow and causing the coils to freeze. If you suspect this issue, inspect the filter and clean or replace it if necessary. You should also check for refrigerant leaks in your system because this problem can cause the coils to freeze.

8. Old HVAC System

How long do air conditioners last? This question is one of the most common ones we hear and has yet to have a definitive answer. The lifespan of an HVAC system can vary depending on the unit type, how often it’s serviced, and the environment. Generally speaking, air conditioners last anywhere from 10 to 15 years before they need to be replaced.

It may be time to upgrade if you have an old HVAC system in your home or business. Newer models are more energy efficient and can save money on monthly energy bills. Additionally, if parts of your current system become worn or damaged due to age, it may be difficult to find replacements. Upgrading to a newer model can help avoid this headache.

9. Air Handler Is Not Working

An air handler circulates the air within your home and is typically located in a closet or basement. If you find that your air handler isn’t working, there are a few things you can check to diagnose the problem.

First, ensure all power switches to the unit are turned on. Next, check for any loose wiring connections preventing the air handler from turning on properly. It is also important to clean or replace the filter regularly, as a dirty filter can restrict airflow and cause issues with system operation.

Although home troubleshooting tips can be helpful, involving a professional HVAC technician is the best solution to diagnose and repair any problems as soon as possible. Doing this will help you maintain a comfortable environment in your home while avoiding costly repairs and irreparable damage to your HVAC.
