If you are like most homeowners, you “remember” your central heating unit during winter. Even if you haven’t been using your appliance it will develop problems. Here are some of the most common central system heating problems and how to fix them:
Radiator noise
The most common radiator noises are knocking noises that are common when pipes have collected trapped air. The noises can also come about when there is no water in the water tank.
If your appliance is making noises you should check the water tank and ensure that there is water. If there is water and still the appliance is making noises, you should bleed the radiator by opening a valve that will allow air to escape the pipes.
Sometimes the cause of the noises is more than this. In such a case you should hire a HVAC technician to have a look at the appliance.
Failure to start
This is the most common problem when your appliance has been “asleep” for a long time. There are many reasons why your appliance may fail to start. One of the reasons is due to failure of the light to re-light. The timer may also have failed or the thermostat may not register.
Sometimes it’s difficult to fix the problems on your own and you have to hire a central system contractor to fix the problem for you.
No hot water
Sometimes the system may be working, but there is no hot water. You should take a look at the thermostat and make sure that it’s set to 60 degrees. You should also take a look at the motorized valve and confirm that it’s open. Sometimes the problem is caused by a lot of air in the hot-water cylinder.
You should bleed the air-release by opening the valve located on the pipe entering the heating coil.
Sometimes you will experience uneven heating. This is common when there is sludge at the bottom of the unit. The ducts may also have leaks. This problem is usually complex and it’s wise that you hire a heating repair professional to inspect the system and fix the faulty areas.
Conclusion
These are central heating unit repair tips for the most common central heating system problems. If you haven’t been using your appliance for long you should always ask a central heating unit contractor to inspect it before you resume use.
