Common Residential Furnace Problems

One of the best things that were ever designed for a home is HVAC units. These systems heat and cool a home in a rapid manner and are very easy and convenient to use. They use forced air as the means of transporting the heated and cooled air so they also tend to fill rooms completely and keep the air in a home from getting stagnant. They are designed to last a long time but that does not mean they are trouble free. Here is a list of some of the more common residential furnace problems .

 

 

1. Blower Unit Failure

 

The blower motors on HVAC units run constantly during the warmer and colder months of the year so it no wonder they are listed under the more common residential furnace problems that a homeowner may encounter. They also tend to be located in attics, basements, garages and other areas that collect a lot of dust. A furnace cannot run if its blower unit fails so it must be repaired or replaced right away if this happens.

 

2. Control Failure

 

Obviously when a control fails on a home furnace chances are the system will not run properly or may not come on at all. It could fail because of such things as a thermostat on the control board going bad or something simpler like a broken activator switch. Either way these must be repaired because you certainly don’t ever want to be without heat during the coldest months of the winter.

 

3. Burner Tray Failure

 

There are perhaps no more common residential furnace problems than those associated with the burner tray. These are constantly being subjected to expansion and contraction during heat cycles which will weaken the metal over time and they also are subjected to a lot of carbon buildup. Even cleaning does not always get them working properly and this can make the furnace run very inefficiently or not come on at all. A burner tray is too important to the proper working of the furnace so it is best to have it repaired or replaced as quickly as possible when there are problems with it.

 

4. Electrical Switches

 

Just because a furnace runs on natural gas, propane or oil does not mean that there is no electricity going to it. Parts such as the controls, blower motor and electronic ignition all need electricity to do their function in an HVAC system. These are controlled by a series of switches that allow each device to come on when it is called for. Over time the action of the switches coming on and off will produce some carbon buildup and this may even cause the metal contacts to melt after a while. These are examples of other vital parts in a home furnace that should be replaced immediately when there are signs that one of these is starting to fail.

 

Yes it’s true that home furnaces last a very long time between major repairs but that does not mean they are impervious to having one of these types of residential furnace problems arise every so often. And more on furnace repairs frequently asked questions http://plumbers-edmonton.ca/
