HVAC Problems That Can Be Diagnosed and Resolved Through Thermal Imaging Cameras

HVAC systems are a common component in most houses nowadays. HVAC systems provide the required cooling during summers and the required heating during winters. Through optimal temperature control, the system ensures a perfect environment inside your house.

Knowing the importance of temperature management inside your house, it is necessary that you treat your HVAC system with the seriousness required. You do not want to ignore problems within the system as they can slowly and gradually become bigger and messier. In this article we mention some of the most common HVAC problems that can be resolved through thermal imaging cameras. Knowing about these problems can help you better prepare for the diagnosis you should run and the solutions you should prepare for them.

Problems Starting Up

Your HVAC system can experience problems starting up because of a sudden increase or decrease in temperature across the air flow vents. The temperature inside your cooling coil should be regularly monitored through a thermal imaging camera. Sudden increases in temperature can clog the system beyond repair.

Ignition problems can also be the result of gas supply issues. It is best to have these issues checked by an expert with thermal imaging cameras. Thermal imaging cameras can be used to pinpoint the problem and to actually find the source behind it.

Ignition problems can also happen because of a wide variety of other reasons. Your pilot could get clogged, a flame sensor could be dirty, or burners might be at fault. Other possible reasons for the problem could include short cycling, delayed ignition from the burners or a furnace lockout.

Temperature fluctuations usually occur because of a lack of maintenance. These systems require regular maintenance so that they can function right. Once you fail to provide the right maintenance, you will see multiple problems arise in the system. It is best to have the system checked and maintained before the start of each new season; summers and winters. Have the air cooling system checked before the summers, and the heater checked and repaired before the winters. Having the internal components fine tuned will prepare you for what is coming your way.

Thermostat Malfunctions

Thermostat malfunctions are also common and play an important role in hindering the output of your HVAC unit. Thermostats are distributed in two major types, programmable and non programmable. If your furnace is not responsible for the problem, then a faulty thermostat could be behind it.

You can solve any problems with the thermostat by referring to your owner’s manual. The manual would help you operate the thermostat in a manner you want. However, if the damage is beyond repair, then you’d need an expert hand.

Additionally, most thermostat problems can best be dealt by studying the temperature across your air intakes and manifolds. Thermal imaging cameras study all relative temperature spikes across the surface of your HVAC system and make sure that the issue at hand is diagnosed and treated in time.

Mechanical Tears

Your heating system contains a number of mechanical parts and components. These mechanical components power the HVAC system, and all of these components run together to create the results.

Mechanical problems usually occur because of a sudden increase in temperature across the exit vents and air intakes. A thermal imaging camera can help you record the temperature across your HVAC system and can eventually help with the due treatment of the problem.

Any problem in these mechanical parts can disrupt the results of the system and can lead you to expensive repairs. Thermal imaging cameras can help in the detection and diagnosis of these mechanical problems.

Filter Problems

Dirty filters are responsible for most of what goes wrong with HVAC systems. Regularly replacing your filters is one of the first things you should get done when looking to check on your HVAC system. Filter trouble can come up at any given time, and it can damage the quality of air coming out of the vents.

Problems in your air filter can be diagnosed by taking temperature readings from across the HVAC system. Temperature readings are perfect for diagnosis, as a blown filter can lead to overheating across the cooling components of your HVAC.

Filters are necessary for your HVAC system because they help determine the flow of air inside the system. Lack of proper air circulation actually puts a strain on your blower and results in multiple comfort issues. A dirty filter can cause your furnace to get overheated and potentially blow up.

Dirty Evaporator Coils or Condenser

You also need to maintain the right temperature inside your evaporator coils and condenser. Optimal temperature is required for these components to function flawlessly. If you want the system to remain active, you should use your thermal imaging camera to pinpoint the ups and downs in temperature across the evaporator coils.

Lack of regular maintenance and inspection on your HVAC system can also lead to dirty evaporator coils. Such neglect can also lead to a dirty condenser in need of repairs. The outdoor coil near the condenser can be cleaned or hosed off by turning the power to the condenser off. However, cleaning the internal evaporator coils isn’t half as easy. You need to get the services of a trained service technician for the job.

Water Leaks

Water and refrigerant leaks from HVAC systems can be harmful for your house and for your health. The leaks usually happen from drainage pipes located inside walls and other solid surfaces. You can always detect such leaks through the use of thermal image cameras.

These cameras will detect the source of the leak and help you diagnose it. Letting such a leak go undetected can result in poor air quality inside the house.
