Sometimes, all you need is a simple fix that will get your furnace back running normally. If not, you should involve furnace repair services. Let’s discuss!
Check The Thermostat Settings
It is often that homeowners accidentally change the settings of the thermostat which results in the furnace blowing lukewarm air. In such cases, your furnace will run but it won’t produce hot air as it is supposed to. That said, the first thing you should check is the thermostat settings.
Make sure that your thermostat is set to “ON” instead of “auto”. If you own an HVAC system, you should know that it comes with several sensors that keep track of the temperature inside your home. This helps the furnace determine how much heat it needs to produce to keep the house warm.
Upon changing the thermostat settings, you notice that the furnace is still blowing out lukewarm air, it is probably a good idea to check the limit switch. If that is working fine, you should move on to the next issue.
A Dirty Or Bad Air Filter
In most cases, homeowners fail to recognize the importance of air filters. Furnaces need clean air filters to circulate hot air properly. If the air filters tend to be clogged, the unit will find it hard to perform at its optimum. That said, you should make sure the air filters are always clean and replaced when needed.
To make sure, consult the user’s manual. Every manufacturer recommends replacing air filters after a certain period of time. Regular inspections and cleaning will ensure that the air filters are clean and the unit performs effortlessly.
You Own A Two-Stage Furnace
You might have not heard of the two-stage furnace but it is very common around the world. The reason these furnaces are common in cold areas is that they come with a different set of valve positions and programming to help keep your home cozy and comfortable.
A two-stage furnace has three valves that open based on your needs and preferences. At its peak, all the valves will open and will offer maximum heat to your house. And since these furnaces in the lower stages do not push as warm air as in the higher stages, you might feel lukewarm air entering your house.
Problem With The Gas Supply
Most furnaces run on propane or natural gas. If you observe that your furnace is blowing cold air, you might need to check the gas supply. The first thing you need to do is call your gas company and check with them if there is a problem with the supply line or the gas itself.
If not, there is a small chance that the problem lies with the thermocouple or the flame sensor. Try turning on and off the furnace to see what happens. If the furnace fails to light up, it means either the thermocouple has gone bad or the flame sensor is broken.
Should I Consult A Professional?
