The HVAC system keeps your home comfortable by regulating the temperatures in the rooms. However, the system is prone to breaking down since it is in constant use. Luckily, you can keep your heating and cooling system in the best shape possible by servicing it regularly and fixing emerging problems in time. This article looks at four issues that call for the immediate attention of a heating and cooling contractor.
1. When the Thermostat Breaks Down
An HVAC system either has a programmable or non-programmable thermostat. Many heating and cooling units fail to work optimally due to an improperly set thermostat. If you notice that your unit is not operating as it should, start by checking if its thermostat is set.
Additionally, the problem may arise when the thermostat's batteries have no power. You should test the batteries in that case and charge them if they are low in power. If you replace the system's batteries and don't solve the problem, call a technician to conduct a proper diagnosis.
2. When the HVAC Causes the Breakers to Trip
A faulty heating and cooling unit can cause the breaker to trip excessively. This occurs when a blockage prevents airflow to the system, causing it to use more power to function. The leading cause of this blockage is the accumulation of dirt in the air filter. This dirt forces the blower to use more energy to force the air through the filter. An overworking blower, in turn, increases the power voltage that the system uses, leading to a power overload that may cause the breaker to trip.
If you notice that the air filter is dirty, remove it and replace it with a clean one, then reset the breaker. If it still trips, hire a technician to identify the underlying problem.
3. When the Mechanical Elements Are Worn and Aged
The HVAC system has several mechanical components. Over time, these elements wear out, lowering the performance of the unit. Some of the elements that wear out fast are the systems bearings and the belt. When that happens, they cause inadequate heating, airflow issues and overheating. Therefore, it is necessary to call an HVAC contractor when you notice excess wear and tear of the unit's components. By replacing them, you will restore the functionality of the system.
4. When the Unit Makes Strange Noises
The HVAC system will produce a strange noise when it develops a mechanical problem. For example, if the system's motor produces whining or squealing noises, it is an indication that its blower or inducer is failing. Any unusual sound calls for urgent repairs to avoid further damage to the internal components.
While the HVAC system issues are inevitable, you can prevent them from escalating by scheduling immediate repairs. Therefore, call a heating and cooling system expert as soon as you notice any of the signs above.
