If your HVAC system isn’t working properly, it can be frustrating and even dangerous. Luckily, there are some common issues that you can easily fix yourself. In this guide, we’ll show you the most common HVAC system issues and how to solve them.

Improperly Sized HVAC System

The most common HVAC system issue is an improperly sized system. This can be due to a number of factors, but the most common cause is incorrect sizing when the system was originally installed. An improperly sized system will not be able to heat or cool your home properly, leading to inefficient operation and higher utility bills. HVAC professionals from Superior Heating and Cooling state that the best way to solve this problem is to have a professional HVAC contractor come out and assess your system to see if it is the correct size for your home. If it is not, they will be able to recommend the proper size unit for your home and install it properly. When your HVAC system is the right size and installed properly, you can get better energy efficiency, cost savings, comfort, and air quality.

Thermostat Issues

One of the most common issues with HVAC systems is thermostat problems. If your thermostat isn’t working correctly, it can cause your system to run inefficiently or not at all. There are a few things you can check to see if your thermostat is the problem: 

• Check the batteries: If your thermostat uses batteries, ensure they are fresh.
• Check the wiring: If your thermostat is hardwired, make sure the wiring is secure and free of any damage.
• Check the settings: Make sure the thermostat is set to the correct mode (heating, cooling, etc.) and temperature.

The best way to solve this problem is to have a professional HVAC contractor come out and assess your thermostat to see if it is working properly. If it is not, they can replace it or repair it so that it works correctly.

Dirty Air Filters

Another common issue with HVAC systems is dirty air filters. These need to be replaced on a regular basis in order to keep your system running properly. Dirty air filters can cause a number of problems, including decreased efficiency and increased wear and tear on your system. In some cases, they can also lead to indoor air quality issues. The best way to solve this problem is to simply replace your air filters on a regular basis.

Refrigerant Leaks

While a refrigerant leak may not seem like a big deal at first, it can actually lead to some serious problems if left unaddressed. First and foremost, a refrigerant leak can cause your energy bills to skyrocket. Since your HVAC system has to work harder to maintain the proper temperature in your home, it will use more energy, which will increase your utility bills.

A refrigerant leak can also cause damage to your HVAC system. The extra strain that your system is under can lead to premature wear and tear, which can shorten its lifespan. In some cases, a refrigerant leak can even cause your system to fail completely.

Finally, a refrigerant leak can also be dangerous to your family’s health. Some refrigerants, such as Freon, can be harmful if inhaled. If you or someone in your family breathes in too much Freon, it can cause dizziness, nausea, and even unconsciousness.

If you think you may have a refrigerant leak, the first thing you should do is contact a professional. Only a trained and experienced HVAC technician will be able to properly diagnose the problem and fix it without causing further damage to your system.

Once the leak has been repaired, you’ll need to have your system recharged with refrigerant. This is a relatively simple process that can be done by most HVAC technicians.

Finally, you’ll need to take some steps to prevent future leaks. First, make sure that your system is installed correctly and that all of the seals and gaskets are in good condition. Second, have your system serviced regularly by a qualified HVAC technician. This will help to keep the seals and gaskets in good condition and prevent future leaks.

Frozen Evaporator Coils

If your evaporator coils are frozen, it can cause your system to stop working altogether. This is usually caused by a lack of airflow, which can be due to dirty air filters or a refrigerant leak. To thaw the coils, turn off your system and check the air filters and refrigerant levels. Once the coils are thawed, you should call a professional to inspect your system and repair any leaks or other problems.

Dirty Condenser Coils

Another common issue that can cause your HVAC system to run less efficiently is dirty condenser coils. These coils are responsible for dissipating heat, so if they’re dirty, it can make your system work harder than it needs to. You can clean the coils yourself with a brush and some soap and water. Make sure you disconnect the power to the unit before cleaning.

If you’re having problems with your HVAC system, there’s a good chance that one of these common issues is to blame. Luckily, most of these problems are easy to fix yourself. However, if you’re not sure what’s wrong with your system or how to fix it, always call a professional for help.
