Your thermostat should trigger your furnace to click on at the right moment. However, you could have several issues that keep your thermostat from operating as it should. You may have a thermostat with an electrical issue, as we just mentioned. Or, you may have a poorly calibrated thermostat. In addition, your thermostat may be situated in an inopportune place in your home, which will make the temperature readings inconsistent. If you have thermostat issues, your furnace may not come on, it may not stay on long enough, or it may be working more than it should, leaving your home overheated. Regardless of the situation at hand, we can take a look, assess the problem at hand, and fix, replace, or move your current thermostat.
BLOWER FAN MALFUNCTION
Your blower fan is responsible for pushing the hot air that your furnace produces through your ventilation system to the rooms throughout your home. If you have a blower fan issue, then hot air may just sit at the furnace (which can lead to additional problems). You should be able to hear your blower fan turn on as your furnace starts up — it will sound just like a fan with a motor. If you don’t hear a fan motor, and can’t feel air movement from the vents in your home, then your motor has failed. In addition, if your fan is making loud noised (often screeching or whining), then your blower may be inefficient and require service. We can fix or replace your blower motor, and we will oil and maintain the motor to ensure that it has a longer service life.
POOR HEAT AT THE VENTS OR COMPLETE FAILURE
If you place your hand over your vents and you aren’t feeling much heat or air movement, then you may be experiencing a variety of issues. As we mentioned, your blower fan may be operating poorly (or not at all). You may also have burner issues, keeping your furnace from producing sufficient heat. Or, you may have a pilot or ignition failure which means that the system won’t work at all. In addition, you may have a blockage in your ventilation system, or you may have an air filter that is dirty, which will make it difficult for your blower fan to pump enough air throughout your home. Due to the complexity of the issue, you may have to have a technician locate the source of the problem — we’d be happy to help!
