3 Signs That You Need Professional Heating Repair

Many homeowners don’t pay much attention to their HVAC system until something goes wrong. When that happens, it can cause huge headaches and expensive repairs.

High energy bills are one of the first signs that your system needs repair. This is especially true if the increase in price doesn’t match your usage habits.

1. No Air is Blowing

If you put your hand under your vents and feel little to no air blowing, this is a clear sign that your HVAC system needs professional attention. You may have a blocked vent or some other issue that requires immediate attention to prevent irreversible damage and ensure proper airflow.

Inconsistent temperatures are another clear indicator that your HVAC system is not working properly. If one room is hot and the other is cold, you have a problem with airflow that must be addressed.

Loud noises from your system can also be a clear sign that it is time to call for repairs. Banging, clanking, and squealing sounds are all signs of loose or damaged components that must be fixed immediately. You should also pay close attention to any smells coming from your unit. Musty or burning odors are indicative of mold and other issues that need to be addressed as soon as possible. With regular maintenance, you can keep your HVAC system running properly and avoid costly repairs down the road.

2. High Utility Bills

When your electric or gas bills shoot up dramatically without any change in your usage, it may be a sign of an HVAC problem. Compressors, capacitors and motors can all fail over time, which will decrease their efficiency and cause the system to work harder to get your home to the temperature set on your thermostat.

Other warning signs that your HVAC system is in trouble include uneven temperatures between rooms, frequent cycling, and poor indoor air quality. Addressing HVAC problems promptly can restore energy efficiency, improve comfort, promote system longevity and extend the life of your ductwork.

Weak or insufficient airflow can also be an HVAC issue, which can indicate clogged air filters, blocked vents or fan motors. Changing your filter can help, but if the issue persists, you may need to call for professional heating repair. Unaddressed, these issues can increase your utility bills and may even result in equipment failure that requires a replacement heating installation.

3. Strange Noises

Strange sounds from your heater are not normal, and can signal that there is something wrong. If you hear clicking, rattling or whistling, turn off your system and call for a professional. Whistling noises may mean that there is a refrigerant leak in the condenser or another problem with the unit. If you hear loud banging or clunking sounds, it could be an indication that the ductwork needs repairs.

Clicking sound is normal when the system turns on or off, but repeated clicking can indicate a serious electrical issue. Rattling sounds are usually caused by loose parts within the system and will need to be replaced by a technician.

Squealing or grinding noises are usually caused by dirty filters, which can damage the motor bearings. It’s important to change your air filter regularly, and if this doesn’t fix the issue, you will need to contact a professional for heating repair. They can replace the worn-out bearings in your motor and restore it to proper operation.

4. Strange Smells

The first time you turn your heater on for the season, it may emit a burning odor. This can be caused by electrical or mechanical issues with your system. If this smell is persistent or occurs every time you turn on your heater, it’s time for heating repair. A burning smell can also mean your system is overheating. Electric resistance heaters, in particular, have plastic parts that can burn out. If you notice a burning smell or hear your carbon monoxide detector beep, evacuate your home immediately and call for emergency services and an HVAC technician.

Any odors or sounds coming from your HVAC unit are signs that you need professional repairs. Rattling and banging sounds usually indicate a motor or fan issue, while whining noises could be the result of a furnace ignition problem. Puddles near your system indicate water leaks that require immediate attention. These are just a few of the reasons why you should keep an eye out for any strange smells, sounds, or puddles when starting up your furnace each fall.
