This can be caused by a number of different issues. Some potential minor causes of this issue may be a dirty flame sensor, burner, or pilot. A more serious cause may be a gas supply problem or faulty ignition. Regardless of what is causing the problem, hiring a trained HVAC technician to diagnose and fix the problem is the best thing to do in this situation. Ignition-related problems may involve exposure to high voltage and natural gas, so it’s best to trust the experts to get it taken care of for you.

When your HVAC system breaks from the norm and starts emitting unusual sounds such as screeching or rattling, it’s a sign that you should get an inspection.

• High-pitched screening sounds usually mean the motor has a damaged or worn-out belt or bearing. Lubrication or the replacement of an old belt is typically all that is needed.
• Loud banging and rattling sounds may indicate a problem with the blower motor, such as a loose component. If you hear rattling or banging, turn your system off immediately and contact your local HVAC technician to get it fixed.
• Thwapping sounds are often caused by debris being caught in the HVAC’s fan blades. This may not be an emergency problem, but it can quickly lead to the blower motor wearing out, so it should be taken care of promptly.
• The outdoor condenser may make a rattling or humming noise, which is typically a sign that something isn’t right — such as a faulty motor or some loose component. Humming can be a sign that your HVAC’s motor is starting to fail and needs to be replaced.

The bottom-line with an HVAC system making unusual noises is that, in most cases, you want to get it checked by a professional promptly. If you are in Northern Colorado — including Fort Collins, Loveland, and Greeley — contact SWAN Heating & Air to get this problem taken care of promptly.

The most common cause of blown fuses and tripped breakers is a blower motor that has been overworked. If your HVAC system is clogged, you can expect there to be more strain on the whole system. When the system has to work extra hard to achieve your desired temperature, a tripped circuit breaker or blown fuse become more common.

There are a variety of different potential causes of a continuously running blower motor. One common cause is simply the thermostat being set to the “on” position instead of “auto.” This causes the blower to work non-stop. If you check the thermostat though and see that it is set to “auto” and it still won’t turn off, the next thing to do is to remove the thermostat from the wall and see if that’s what’s causing the problem. If, after that, it still doesn’t turn off, you should seek the help of professional HVAC technicians.

If the drain lines of your HVAC system become damaged or clogged, it can lead to water leaks. Other possible sources of leaking water include the heat exchange, the evaporator drain pan, and the collector box. If left unaddressed, leaking water can cause damage to both your HVAC system as well as to your property. You can clean your drain lines by pouring some bleach into them occasionally, though, the most surefire way of preventing these kinds of issues is to get regular preventative HVAC maintenance.
