5 Critical Furnace Repairs Every Homeowner Should Be Aware Of

Furnace repairs can be intimidating, especially when you're not sure what's wrong. There are simple things that every homeowner should know about their furnace and furnace repairs. This way they'll be able to help remove any confusion when an issue arises and better understand the process. So here is a list of five common furnace issues.

Igniter Failure

Your furnace's igniter is a small wire coil located in the firebox that uses electric current to ignite the gas for your furnace. If it fails, burners will not light properly and the combustion process will be hindered. You need to contact the furnace repair technician to fix the issue.

Gas Valve Failure

A gas furnace requires a constant supply of natural gas, and if your home does not receive this supply the gas valve will shut off. When this occurs, the furnace will stop producing heat and either make a clicking or buzzing sound or no noise at all.

Malfunctioning Thermostat ​

If your thermostat is malfunctioning, you may notice that your home isn't getting as warm as it should. Even if this just occurs sporadically, don't ignore it. A faulty thermostat could cause overheating of internal components which can lead to permanent damage or even a fire. You should have an HVAC technician come in to address this quickly before more damage is done.

Blower Motor Failure

Your blower motor draws air over the heat exchanger coils to circulate cool air through your home during winter months and keep all the rooms in your home heated equally. A noisy blower means that it is not working properly, so have an HVAC technician ready to inspect and repair.

High Pressure Switch Failure

When the combustion process in your furnace's firebox isn't complete when exhaust gasses are vented through the flue, high levels of these gasses can build up around the hot exterior components of your furnace. This can lead to carbon monoxide poisoning or even a house fire. To prevent this dangerous scenario from occurring, your high pressure switch should shut off the gas supply if the outside temperature drops too low for proper venting. If you notice that your basement or other rooms in your home do not seem warm enough during cold winter months, but the thermostat is indicating that your furnace's heat is on, it could be due to high pressure switch failure. If you suspect this may be the case, immediately turn off the power supply to your furnace before calling an HVAC technician for repairs.

cool and hot areas of the home

I live in an older home that we are working to renovate. There are three areas of the house that just don't seem to get cool in the summer or get warm in the winter. I have done all that I can to try to keep these areas comfortable, but I wasn't able to do much until I hired an HVAC technician to come out and figure out why those areas were so uncomfortable. This blog will show you what can be causing areas of your home to be less comfortable than other areas when it comes to temperature during both winter and summer.
