1. Weak Airflow or Poor Cooling/Heating

What to Look For: If your AC is blowing weak or warm air, or your heater isn’t keeping your home cozy, your HVAC system might be struggling.

Why It’s a Problem: Weak airflow could indicate a clogged filter, blocked ducts, or a failing blower motor. In Greensboro, Burlington, Winston-Salem, Randleman, and Asheboro’s extreme weather, can lead to discomfort and higher energy bills.

What to Do: Check your air filter (replace if dirty) and ensure vents are clear. If the problem persists, call Probus: Heating & Cooling for a thorough inspection.

2. Strange Noises from Your HVAC Unit

What to Look For: Hearing banging, rattling, or squealing from your HVAC system? These noises aren’t normal!

Why It’s a Problem: Unusual sounds could signal loose parts, a failing compressor, or debris in the system—common issues in Greensboro, Burlington, Winston-Salem, Randleman, and Asheboro due to dust or seasonal changes.

What to Do: Turn off the system to avoid further damage and schedule a professional repair with our team. We’ll diagnose the issue and get your system running quietly again.

3. Unusually High Energy Bills

What to Look For: A sudden spike in your energy bills, especially during Greensboro, Burlington, Winston-Salem, Randleman, and Asheboro’s hot summers or cold winters, could mean your HVAC system is working harder than it should.

Why It’s a Problem: Inefficiencies like low refrigerant, dirty coils, or a failing thermostat can cause your system to overwork, costing you more.

What to Do: Compare your bills to last year’s. If you see a significant increase, let Probus: Heating & Cooling check for underlying issues like leaks or worn components.

4. Frequent Cycling or Constant Running

What to Look For: Does your HVAC system turn on and off too often (short cycling), or does it run nonstop without cooling or heating effectively?

Why It’s a Problem: This could be caused by a faulty thermostat, electrical issues, or an oversized/undersized unit—problems we often see in Greensboro, Burlington, Winston-Salem, Randleman, and Asheboro homes.

What to Do: Reset your thermostat (as outlined in our 3 Easy AC Fixes post) and check for obstructions. If the issue continues, our technicians can assess your system for proper sizing and function.

5. Unusual Odors from Vents

What to Look For: Musty, burning, or chemical smells coming from your HVAC vents are a red flag.

Why It’s a Problem: Musty odors might mean mold in your ducts, while burning smells could indicate electrical issues—both serious concerns in Greensboro, Burlington, Winston-Salem, Randleman, and Asheboro’s humid or dry climate.

What to Do: Don’t ignore strange smells. Contact Probus for a professional inspection to ensure your system is safe and clean.
