The pressure transmitter comes in a number of shapes and sizes. One, referred to as a Bourdon Tube, is designed especially for monitoring non-liquid pressure. They are relatively inexpensive and good for measuring air and gas pressure in compressors. The tubes may be c-shaped, spherical and helical.
Average Pay & Benefits. The BLS groups heating technicians under the job category of Heating, Air Conditioning, and Refrigeration Mechanics and Installers. These technicians earned average incomes of $45,540 per year as of May 2011, according to the BLS. Their incomes are based on both regular and overtime pay.
Since HVAC costs typically account for 65 â 75% of a utility bill you could see an average savings of $150.00 per month. Therefore, after we pay $200.00 per month (and save $150.00 in utility costs), we have installed a brand new highly efficient geothermal heating and cooling system for a net of $50.00 per month.
