Your HVAC system is a complicated machine. You’ll need a trained professional to diagnose and fix any issues with it. However, having some basic HVAC troubleshooting knowledge will help you understand the problem better and take care of simple HVAC issues in your Gilmer, Texas, home. Here are some of the most common issues homeowners face and some HVAC troubleshooting tips:

Uneven Heating or Cooling

If the temperature is different throughout your home, you most likely have an improper air duct balancing issue. Either the airflow in some rooms is high or the vents in some rooms are closed. 

Adjust the dampers to optimize the air flow, and open the closed vents. If the air filter is dirty, replace it. Sometimes, the problem is due to poor insulation, fan speed or duct obstruction.

Poor Airflow

If you’ve always experienced poor airflow, your home’s ductwork might not be sized correctly or installed properly. However, if the airflow has weakened recently, check the air vents. Make sure they are open and not blocked by furniture, curtains or other objects.

Next, check the dampers. If any of them are closed, open them by turning the handle so it’s in line with the duct. Other reasons for poor airflow include a dirty air filter, faulty blower motor and worn-out fan belt.

Weird Noises in the Outdoor Unit

If you hear a loud metal-on-metal noise, it might be due to fan blades hitting something. Open the unit, and remove ice formation or any other obstruction from the blades.

Sometimes, vibrating loose parts are to blame. A trained professional should tighten them. He or she can also address sounds caused by a bad motor, broken fan blades and a loud compressor.

If you need professional help fixing any of these issues, contact the experienced HVAC technician technicians at JD’s A/C at (903) 759-7483. We look forward to troubleshooting your HVAC issues and restoring your comfort.
