HVAC (heating, ventilation, and air conditioning) systems are necessary to run your home properly. A functional HVAC system is essential for comfort within the house. Their constant use means that they are liable to have issues at certain times.
Knowing the possible issues you might face can help you to plan and notice the symptoms when they occur. Treating HVAC issues quickly can help with maintenance and prevent issues from escalating. In this guide, you will learn 5 of the most common HVAC system problems and their solutions.
Thermostat Malfunctions
Thermostat malfunctions cause your HVAC to perform poorly or not at all. These malfunctions can cause the HVAC to turn on and off erratically, temperature fluctuations, inefficient energy usage, and short cycles. Dead batteries, incorrect settings, and outdated models are the common causes of thermostat malfunctions.
You should refer to your owner’s manual to ensure that it is set up correctly. Check the batteries in the thermostat and replace them if necessary. Consider upgrading the thermostat for better performance. If problems persist, contact a professional to examine the thermostat.
Low or Leaking Refrigerant
Leaking refrigerants can reduce the cooling efficiency of your HVAC and harm the environment. It can also cause ice buildup on evaporator coils and hissing sounds. The refrigerant is the vital component required for cooling, and low levels reduce efficiency, damage the compressor, and blow warm air. Scheduled maintenance and inspections can help prevent leaks or low refrigerant levels. Hire a licensed HVAC technician to repair leaks and refill the refrigerant to optimal levels. Proper refrigerant levels help with energy use and prevent your system from consuming much energy.
Dirty/Clogged Air Filters
This is one of the most common HVAC issues and also the easiest to fix. The job of air filters is to trap dust and debris to keep the air flow fresh. As time passes, this dirt clogs the filters and forces your HVAC system to work harder. This leads to higher energy bills and poor air quality, which is harmful to your health.
Filters should be swapped every two to three months as recommended by the manufacturer’s guidelines. Inspect your filters every 60 to 90 days and replace them quickly. This reduces the energy needed for the system to work and prevents overheating, which can shut down your HVAC system.
Drainage Problems and Leaks
Clogged drain lines pose a serious threat to your HVAC system and can be disastrous when left unchecked. When your air conditioner pulls excess humidity from the air during hot weather, the water collects and drops into a drain pan, then is funneled out through the drain pipe. If you discover puddles around your HVAC system, then that is a sign of drainage issues or water leaks. Water leaks can lead to property damage and mold if left untreated. Once leaks are noticed, professional cooling specialists should be called in to trace the source and fix the problem.
Electrical Problems
Unchecked electrical problems can lead to system failures and damage your HVAC system. These issues arise when the system is overworked or due to faulty installations. Tripped breakers, faulty wiring, and burnt connectors are some of the common electrical problems HVACs face. You need to call in a professional HVAC technician to examine your system. Avoid using DIY fixes for your HVAC system because bad repairs can further damage it.
Endnote
Your HVAC system should be adequately maintained to get the best performance. Frequent maintenance should be a part of your schedule. Replace the air filters every three months or earlier if you have allergies. If you notice electrical faults, call a professional to fix the issue and avoid DIY fixes. Finally, pay attention to your refrigerant and ensure it is at optimal levels.
