A Maintenance Walk-through of an HVAC Technician

As you may know, HVAC stands for Heating, Ventilation, and Air Conditioning. The trained HVAC technician who comes to your home to inspect your system or perform preventive maintenance will check all the systems. Or they can check a specific one, depending on your requirement. For inspecting a furnace and an air-conditioner, here is a look at the working of an HVAC Technician on a standard call.

 Steps for Furnace Inspection and Maintenance of an HVAC Technician 

  1. Replacement of the air filter. Ideally, replacement should do it about 4 times a year. You may also ask your technician to show how the technician can change a filter. 
  2. Checking and properly calibrating or setting the thermostat. An HVAC technician will recalibrate it if it is out of sync, which will help you save on energy bills.
  3. Inspecting connections and tightening any loose ones as needed. An HVAC technician will also measure the voltage and the current on the motors and then lubricate the moving parts if needed.
  4. An HVAC technician will inspect the condensate drain in your furnace or boiler.
  5. The HVAC technician will also check system controls to ensure they are operating correctly and safely.
  6. A good HVAC technician will let you know if there is a need for any repairs based on their inspections. They may provide a quoted price for repairs before doing the work.

Most HVAC technicians follow the above rules when inspecting a furnace. Some Dryer Vent Cleaning in Canton services may also follow these steps for dryer vent inspections.

Steps for Air Conditioner Inspection and Maintenance of an HVAC Technician 

  1. The first thing checked is probably the condenser coil. It will be cleaned with either pressurized water or a chemical cleaning agent if it is filthy.
  2. An HVAC technician will check the thermostat next by running it for 5 to 10 minutes at a lower temperature to ensure proper working at the required operating pressure.
  3. The technician will take a wet bulb reading next to see if there are any issues there.
  4. Super-heat and the sub-cooling system will be inspected to make sure your air conditioning system is charged correctly.
  5. There may be an issue with motor amperage, which an HVAC technician will inspect, so it meets the manufacturer’s specifications.
  6. If the technician found any problems in the above steps, they will let you know the cost of each issue and make all necessary repairs after.

 Steps you can take to Prevent Problems and Save money

As we know, a routine inspection and maintenance can save money in the long run. Malfunctions can occur at any time and may not be easily detectable, which can lead to a replacement for your furnace or air condition. Inspections can help detect possible issues earlier that can save you additional cots later.
