Everyone wants to feel comfortable in their own homes. This is why most homes have heating, ventilation, and air conditioning units so they can control the ambient temperature. However, keeping the systems in pristine running condition can be challenging as these mechanisms have many moving parts prone to wear and tear. 

This is why if you have an HVAC system, you must have the contact number of a reputable technician handy. When your system breaks down, you can easily schedule an appointment to minimize the discomfort the system failure would bring. It is also best to work with reputable local enterprises so you can have easy access to their services. For example, if you're in Aurora, IL counties, you can look up trusted companies near you to minimize wait time. You can partner with an experienced heating and cooling Aurora, IL company to ensure that you continue to enjoy a terrific temperature-controlled environment. 

Meanwhile, here are some common HVAC concerns you can avoid with regular maintenance check-ups.

Faulty evaporator coils

Evaporator coils, or evaporator cores, are the components in the HVAC where the refrigerants absorb heat. This is where the cold air comes from. These components are made of steel, aluminum, or copper. If the coil becomes dirty, the efficiency drops, and the system won't produce as much cold air as you're accustomed to, leading to temperature fluctuations. Have your technician clean the coils as efficiently as possible.

Dirty air filters

Air filters are the HVAC components that filter pet dander, pollen, dust, and other particulates from the air you and your family breathe. These minute particles become trapped in the filter, preventing them from recirculating. Dirty air filters will reduce air quality and cause allergies to manifest. Therefore, you must always check whether the filter is clean enough. When filters become too dirty, you must ask a technician to replace or clean them thoroughly.

Ductwork problems  

Most homeowners overlook ductwork problems as a cause of HVAC trouble. These airways connect the system to air vents throughout the house. If the ductwork is dirty, leaking, or faulty, there’s a huge chance that your air and temperature quality will be significantly affected. Over time dust and other particulates accumulate in the ducts and cause discomfort, and may even lead to health problems. You must ask your AC technician to clean the ducts and check for leaks periodically.

Refrigerant leaks

Refrigerants are chemicals that produce a cooling effect when they vaporize or expand. Most HVAC systems use R-22 or R-410A refrigerants. R-22 refrigerants are the old standard for HVAC systems and are continuously being phased out. Meanwhile, R-410A refrigerants meet stringent environmental guidelines and are the alternative to R-22 chemicals.  

Once your HVAC system leaks refrigerants, your system performance can fluctuate. HVAC systems don’t run well if they have low amounts of refrigerants. Loose fittings, corrosion, holes, and component breakage can cause leaks. The best way to prevent leaks is to have your technician conduct regular check-ups and cleaning.


HVAC systems are essential to a thermally comfortable home environment. Regular maintenance checks from reputable technicians can prevent common HVAC system problems.
