In most corners of our nation, people use their HVAC systems all year long. Though there are days when the weather is comfortable enough to turn off the heater or air conditioner and let fresh air into your home, those are generally few and far between. For the most part, you count on your heater to keep the chill out of the air or your air conditioner to keep heat and humidity at bay.
HVAC systems are designed to withstand constant use. They can last for around 10 to 15 years before succumbing to wear and tear, especially with proper maintenance. Still, times will come when your heat and AC units need repairs. Letting those times catch you off guard can leave you suffering through extreme heat and cold. Knowing how to spot the early warning signs that repairing your HVAC may be necessary can keep that from happening.
Unusual Odors
Unusual odors can be indications that you need HVAC repairs. This warning sign often goes ignored, but it’s important. Be mindful of burning odors because they may indicate that your system is overheating. Electrical smells, such as hot plastic or burning rubber, usually warn of issues with the wiring, connections, or electrical components of a heating system. Musty smells may mean that there’s mold or moisture in the units or ductwork. A chemical odor coming from the vents could mean you have a refrigerant leak.
Low Airflow
You should be able to feel air blowing from your vents from a few feet away. If you can’t, your HVAC system isn’t blowing properly. That could be a warning sign of several issues. Clogged filters and blocked or damaged ductwork are a few of the possibilities. Low airflow may also indicate that your compressor is locked up or the blower motor is malfunctioning. No matter what’s restricting your HVAC system’s airflow, it can lead to poor indoor air quality, detract from your comfort, drive up your heating and cooling costs, and cause other problems.
Strange Noises
Many people overlook strange noises coming from their HVAC systems, and they usually come to regret it. If you’re hearing rattling, chattering, or squealing coming from the system, that’s a surefire sign of trouble. If the blower just seems to be roaring a bit louder than usual, that could be a warning sign as well. Loose components, broken belts, worn-out blower motors, and many other problems can cause unusual noises. They’re essentially your heating and air conditioning systems’ cries for help.
Rising Heating and Cooling Costs
Finally, it’s important to pay close attention to your utility bills. If your monthly power bills, or gas bills if you have a gas furnace, seem to be creeping higher, HVAC malfunctions and efficiency loss could be to blame. It’s normal for heating and cooling costs to creep up a bit in extreme temperatures, but those increases should be temporary. Consistent upticks often point to a need for repairs, and that warning sign can show up long before unusual noises, smells, and other problems present themselves.
Keeping Your HVAC System in Optimal Condition
Unexpected HVAC malfunctions can leave you in dire straits. In truth, though, most malfunctions aren’t quite as unexpected as homeowners think. Heating and air conditioning systems send out signals to let you know they’re in need of professional attention. Keep the early warning signs mentioned here in mind, so you’ll know in advance if your HVAC system needs repairs.
