You want to ensure your family is comfortable and safe in your home regardless of weather conditions. Your HVAC (Heating, Ventilation, and Air Conditioning) systems control the climate in your home. The boiler is one of your HVAC system's most critical and complex components to maintain. Boiler repair issues can cause stress and frustration if left unattended. This guide covers the most common boiler repair issues in residential HVAC systems so that you can identify them and take the necessary action to fix the problem.
One of the most common boiler repair issues is low pressure. Low pressure often occurs due to leaks in the system, which can cause a pressure drop. If not addressed on time, low pressure can lead to cold radiators and a lack of heating in the house. In such a situation, it's best to call a qualified HVAC technician to locate and fix the leak.
Have you ever heard a loud, rumbling noise from your boiler? If yes, then it's likely that your boiler has a kettling issue. This rumbling occurs when limescale buildup inside the boiler causes it to overheat. The best way to avoid this issue is to ensure that your boiler undergoes routine maintenance and cleaning.
Faulty Pilot Light
The pilot light in your boiler serves as an essential safety feature. If the pilot light goes out, this may result in an inefficient heating system or, in severe cases, carbon monoxide poisoning. Common causes of a faulty pilot light include gas supply problems or broken thermocouples. It's advisable to call in a professional technician to fix this issue immediately.
The thermostat in your HVAC system controls the temperature in your home. If it is faulty, it can cause inconsistent or inadequate heating. Thermostat issues arise due to a faulty wiring connection or a problem with the temperature sensor. In this case, it's best to call an expert to diagnose and fix the issue quickly.
A malfunctioning ignition system will prevent your boiler from producing heat. This issue can occur if the ignitor is dirty or damaged. In some cases, a clogged burner can also cause this issue. If you've noticed that your boiler is not producing heat despite the pilot light being on, then an ignition failure is the likely culprit.
A well-maintained boiler is crucial for an efficient and safe residential HVAC system. Therefore, it's essential to identify and address common boiler repair issues right away to prevent further damage. Regular maintenance and professional servicing are the best ways to minimize the risk of these issues occurring in your HVAC system. Contact a residential HVAC service near you to learn more.
