Eight Most Common HVAC Repair Issues; Insights from a Warrenville Heating and Air Conditioning Company
Although Heating and Air Conditioning systems are designed to be reliable and durable, they do occasionally need maintenance and repairs. In general, these problems are common across most units. Even though some problems can be addressed by the owners, most will require professional attention.
In this post, we’ll discuss some of the most common heating and air conditioning repair issues faced by homeowners in Warrenville:
1. Dirty Filters
HVAC filters serve the important purpose of preventing dirt, dust, and other debris from entering your home. Over time, they can become clogged and need to be emptied or replaced regularly. If homeowners forget to complete this maintenance task, clogged filters can cause added strain to the HVAC unit. This can lead to operational issues such as poor airflow and premature wear and tear of the important components in the unit.
2. Malfunctioning Thermostats
The thermostat triggers the temperature control of the furnace in the winter, and the air conditioning unit in the summer. After installation, it is important for the homeowner to operate the thermostat as per the manufacturer’s specifications. However, if the thermostat fails to trigger the furnace or start the cooling unit, it likely needs to be examined by a technician.
3. Damaged Gas Valves
The primary function of the gas valve is to provide an adequate flow of gas for combustion during the colder months. The gas valve is generally exposed to nature and is subject to abrasion, so it’s possible that it may not be functioning as it should. In such cases, the valve should be replaced by a licensed professional.
4. Blown Fuses
Apart from a thermostat malfunction, a blown fuse could be one of the main reasons for a unit not starting up. The function of the fuse is to basically prevent the overheating of the compressor or motor. A faulty electrical connection or a circuit breakup could lead to a blown fuse, which is more common in an older unit. Regardless, it will likely need to be checked and replaced by a qualified HVAC technician.
5. Refrigerant Leaks
If your HVAC system is not cooling effectively, but rather blowing warm air, chances are that refrigerant is leaking either from the evaporator or condenser coil. These leaks are generally beyond repair, and the parts will need to be replaced.
6. Compressor Issues
The function of the compressor is to compress the refrigerant liquid as it carries heat out of the house. The compressor is a hardworking part of the unit that can sometimes stop working if the refrigerant levels are either too high or too low. Compressor issues will need to be ascertained by a technician to keep the compressor—and the unit as a whole—functioning properly.
7. Clogged Drain
Debris and dirt can block and obstruct the drain lines. This can cause the pan to overflow, which often results in water damage to the unit’s housing. Although this is primarily a cleaning job, it is a complicated one that’s best left to be handled by a professional.
8. Duct Problems
The build-up of dust or debris can block air ducts, causing it to obstruct the airflow coming from the HVAC unit. Alternatively, if the duct is leaking air, it will cause the system to work harder to maintain the desired temperature in a room. It’s recommended that you have regular duct cleanings performed in order to avoid such problems.
