Your furnace is what keeps your home warm and cozy during those long, cold winter months. It can prevent your family from getting sick from low temperatures and can create an inviting space for you to unwind at the end of the day. However, with all that hard work it is doing, your furnace will eventually need to be tuned up. Here is how to tell if it’s time.

1. The Heat Temperatures are Low

If your furnace is not creating enough heat anymore, it might be a sign of a problem. Try to turn up the heat manually or have a professional do it for you. See if that fixes the issue. If it doesn’t, then it may be time for you to have your unit serviced. There could be a problem with your manifold. It is responsible for producing the flame that heats the air inside your furnace. If you notice cooler air blow from your vents, it’s time for a furnace tune-up.

2. The Air Pressure from Your Vents is Weak

If the air coming out of your vents is nice and hot but not very strong, then you could have an issue with the blower motor. This is what produces air pressure within your unit.  A blower that needs a tune-up will render a weak current and should be checked right away.

3. The Thermostat is Not Functioning Properly

This is one of the key components to a properly operating furnace, so if it is not working right then your entire unit will not run correctly.  Begin by checking the wire on the wall unit to make sure it is functioning properly. If your thermostat is below par, it is a good opportunity to upgrade to a new programmable thermostat for better energy efficiency.

4. There are Problems with the Pilot Light

A pilot light that keeps going on unexpectedly is a sign of your furnace needed some attention.  Keep in mind that issues here can be dangerous when addressed haphazardly.  For safety reasons, it is best to have a professional HVAC contractor do this for you. If there is indeed a problem, the HVAC contractor will be able to address it safely and promptly.

5. The Filter is Clogged

If your filter is clogged, it will restrict the airflow to the furnace and suffocate it.  Your air flow will suffer, your unit will work harder, and your bills will get higher.  Maintain a clean filter by having your furnace tuned up at least once per year.
