Is a Need for Thermostat Repair Indicative of Other Potential Heating Issues?

A faulty thermostat can be very annoying during the winter and summer seasons. You need your HVAC system properly functioning during these seasons for a comfortable living. A thermostat that needs repair can be indicative of other potential heating issues. Here is how.

1. Debris and Dust

A thermostat that is dirty can lead to sudden system failure and erratic operation. To solve this problem, you need to uncover your thermostat, and gradually clean the internal components, including the switch contact surfaces and the bimetallic coil. First, you need to set the thermostat to its least setting and utilize a compressed air can or soft brush to clean the bimetallic coil. You then need to set the thermostat to the highest setting before cleaning the coil again. Finally, configure the thermostat to the setting you prefer.

2. Mismatched Components

Ensuring your heater operates properly needs proper matching of your thermostat to your furnace system. Thermostats with low voltage are mostly utilized in residential applications. Your thermostat has to be matched to your furnace system depending on the capacity, capability, and type of the heater. Setting up the wrong thermostat type can result in miscommunication and cause system failure. To ensure correct matching, consult HVAC professionals or bring your thermostat when buying updated or new equipment.

3. Poor Wiring

Aging and faulty wiring, disconnections, and loose connections can cause your thermostat to lose the connection to your cooling and heating systems. This leads to an interruption in service. In case your heater quits working properly, it is ideal to check the wiring of your thermostat. If you suspect wonky wiring, make the wiring firm and replace wires as needed, or consult with an HVAC professional.

4. Heat Anticipator Issues

A majority of non-digital, mechanical thermostats have an electrical resistor device at their center. This device is a small metal tab called a heat anticipator. It informs the thermostat when to switch off the furnace burners. When it fails to function properly, it may lead to the cycling on and off of your furnace more often than needed. If your heat anticipator is not properly set, it will need to be adjusted. However, mechanical thermostats have to be manually adjusted, usually using an amp meter in determining the correct setting. At times, you can lightly push the heat anticipator on both sides to solve the issue.

Conclusion

When a thermostat fails you, remember to verify these four issues before deciding to replace it. If you encounter this issue, call us now at 408-295-2182.

What Is Included In An HVAC Tuneup?

Are you wondering why your company is spending more money on electricity?

When you first install your heating and AC units, you will notice that your electric costs are fairly low. Modern technology has made our heating and cooling systems much more efficient than in past years. However, heating and cooling units degrade over time. Much like your car, heating and AC units are mechanical and need to be serviced in order to reach their full potential.

This is when an HVAC tune-up is needed.

What Happens During An HVAC Tune-Up?

An HVAC tune-up is an annual inspection and repair of your heating and ac units. A tune-up will keep your systems running at peak efficiency so that they will last longer and cost less money to use.

When the service professional arrives at your business, he will spend anywhere from one to two hours inspecting and performing maintenance on your units.

He will identify what parts of your units are not working at their peak efficiency.

What Happens During An AC Unit Tune-Up?

When tuning up your AC unit, the service professional will:

  • Adjust your thermostat
  • Clean your air filter
  • Repair exposed wires
  • Ensure that your fan is blowing
  • Measure the amperage of the compressor

There are many other smaller tasks that your professional will do such as inspecting your indoor coil and testing your capacitors.

If your AC unit frequently freezes, the inspector will look for blocked airflow, refrigerant leaks, and issues with internal coils. A frozen AC unit can be unpleasant during the warmer months. Frequent tune-ups can prevent the situation from happening.

What Happens During A Heating Unit Tune-Up?

When tuning up your heating unit, the service professional will:

  • Inspect the internal heating elements
  • Check the burners for proper ignition
  • Adjust the flame sensor
  • Test the carbon monoxide detector

During the inspection, the exterior will be analyzed for leaks, corrosion, and proper ventilation. This inspection and tune-up can help your heating unit last for many years and run at peak efficiency.
