If you feel like some parts of your home are cold, while others are uncomfortably warm, your hvac system may have some balance problems. Here are a few reasons the areas in your home may be improperly heated:
undersized heating system. Small conventional furnaces , heat pumps, or oil furnaces may not be large enough to heat your entire home, especially if additions have been made to your home. You can correct an undersized heating system by adding a secondary heating system like a ductless mini split to specific areas, or by replacing your existing unit.
Furnaces can experience a range of issues over time. Here are some of the most common problems you might encounter: no heat or insufficient heat: if your furnace isn’t producing enough heat or none at all, it could be due to a faulty thermostat, a malfunctioning pilot light or ignition system, a clogged air filter, or a malfunctioning blower motor. Strange noises: unusual noises like banging, screeching, or rattling coming from your furnace could indicate issues with the blower motor, fan, or other internal components. Ignoring these sounds can lead to more significant problems down the line. Frequent cycling: if your furnace turns on and off frequently without adequately heating your home, it might be due to a clogged air filter, a malfunctioning thermostat, or improper sizing.
Furnace Does Not Blow Air
When the chilly winds of winter start to blow, your furnace becomes an indispensable part of your home's comfort system. However, like any mechanical system, furnaces are prone to issues that can disrupt their performance. As hvac experts, we have encountered numerous furnace problems over the years. We'll discuss six common furnace problems and what you can do to address them. 1. Lack of heat production
problem: your furnace is running, but it's not producing enough heat to keep your home warm. Solution: this issue can often be attributed to a dirty or clogged air filter.
A dirty filter restricts airflow, making it harder for the furnace to heat your home efficiently.
Next, when troubleshooting your gas furnace, turn your attention to the furnace’s blower. Problems with your furnace blower include your system not blowing air. This issue could be occurring because the blower is clogged or blocked by debris. Make sure that your furnace door is completely closed. If it’s open, the furnace will not work properly. If you want to check the blower’s belt, first turn off the furnace breaker. If the belt is cracked, frayed, or broken, it will need to be replaced. Consult your furnace’s owner’s manual for the specifications of which belt you need, then simply replace it.
Gas Furnace Blower Runs Continuously
Some oil furnaces have two master switches. One is located near the burner unit, and the other is near the furnace housing or even at a distance from the furnace. Make sure these master switches are both turned to the on position. Limit switch the limit switch is a safety control switch and is located on the furnace just below the plenum. If the plenum gets too hot, the limit switch shuts off the burner. It also shuts off the blower when the temperature drops to a certain level after the burner has shut off. If the blower runs continuously, either the blower control on the thermostat has been set to the on position, or the limit control switch needs adjustment.
Blower running continuously — this might be caused by a bad limit switch. Furnace turns on and off rapidly — this could be related to an old air filter. If the filter is ok, odds are there is a motor or belt issue that will require a professional. Gas smell — a gas leak is dangerous and you should immediately exit the home and call the gas company for an inspection. The furnace doesn’t blow air — you should be able to see through the inspection window to see if the blower is clear of debris. You’ll probably see a red or green light.
If your furnace comes on but one or two rooms are cold, first make sure all the room registers are open. Then examine any ductwork you can get access to and look for gaps between sections or branching points. Seal any gaps between sections of duct with special metal duct tape. Don’t use standard cloth duct tape—it quickly deteriorates, and it may also cause ducts to leak if it was used to seal sections in the past. Make sure you know why your furnace is leaking water. Also check for handles protruding from the ductwork. These are dampers or air conditioner bypasses—make sure they’re open.
