4 Reasons Why Your HVAC Unit is Overheating

Taking care of an HVAC unit can avoid future complications such as overheating. A neglected HVAC unit often experiences issues that can impact its functioning. It is essential to understand the reasons behind an overheating system to get an appropriate solution. Here are four aspects that cause an HVAC unit to overheat.

Clogged Air Filters

HVAC units use air filters to keep dust and dirt at bay. Clogged air filters result in poor indoor air quality, making a household uncomfortable. Clogged air filters can also translate into higher energy bills, given that the HVAC unit has to overwork itself to maintain the optimal temperature level. It can also cause overheating, and eventually, the entire system breaks down.

Dirt Accumulation

The condenser coil’s role is to collect and condense the refrigerant vaporized inside the house by moving it away from the HVAC unit. Letting dust accumulate inside the condenser coil can cause malfunctioning and overheating. When this happens, the HVAC unit overworks to meet the desired temperature, triggering an increase in energy bills. However, letting a professional HVAC unit cleaner inspect and clean the condenser coil regularly can help resolve this issue before the entire system breaks down.

An Aging HVAC Unit

HVAC units are like any other machines or devices in which their lifespan has an end. The performance of a heating and cooling system can drop if it has exhausted its working life. Consequently, the already aged components might start to overheat and fail to regulate your home’s temperature. It is best to replace a unit approaching the end of its working life to avoid falling victim to overheating issues. The lifespan of an HVAC unit can vary based on its quality and manufacturer. Most of them run up to 15 to 20 years before they start misbehaving. Signs of overheating could mean that the HVAC unit has exhausted its lifespan. It is wise to inquire about the age of a heating and cooling system before purchasing it. Keep monitoring its performance to know when it is due for replacement.

Refrigerant Leaks

Refrigerant leaks can impair the capability of an HVAC unit to keep a room comfortable. Lack or insufficient refrigerant forces the HVAC unit to overwork, leading to overheating issues. Getting the HVAC unit regularly inspected by a professional can help prevent refrigerant leaks or other safety issues.

It would be best to consider contacting a professional HVAC technician if your HVAC unit is overheating. At Christian Heating and Air Conditioning, our experts can analyze your HVAC system’s issue to ensure it is running in tip-top shape.
