  6. <h1 style="text-align: center;">Tips For Commercial HVAC
  7. And In North Texas</h1>
  8. With the North Texas region being subject to various <a href="https://www.iweathernet.com/texas-dfw-weather-records" target="_blank">temperature extremes</a> during a
  9. calendar year, ranging from high winds to hail to <a href="https://www.weather.gov/fwd/dgr8mxmn" target="_blank">single-digit
  10. temperatures</a> to weather above 100 degrees and humid, heating
  11. and cooling technicians have to be ready to handle a wide array of
  12. problems not commonly found in other areas of the country.
  13. &nbsp;This requires a HVAC professional to understand virtually
  14. everything that a heating and cooling professional can learn - with the
  15. exception of sub-zero conditions!<br>
  16. <br>
  17. <a href="https://www.supertechhvac.com/commercial-hvac-systems/" target="_blank">This resource from Maryland</a> wrote
  18. a comprehensive guide to the basics of commercial HVAC. &nbsp;Here
  19. are some points from that article:<br>
  20. <br>
  21. <ul>
  22. <li style="font-style: italic;">A commercial HVAC
  23. (heating, ventilation and air conditioning) System has the same
  24. objective as a residential HVAC system - to keep the building occupants
  25. cozy with high quality air in a 72-degree environment, the humidity
  26. ranging from 40 to 60 percent.</li>
  27. <li style="font-style: italic;">The heating of air is
  28. often achieved through burning fuel (gas, oil, electricity). Cooling
  29. the air is the opposite (naturally), with a process that extracts hot
  30. indoor air and cools it through refrigerant or water-cooled systems,
  31. eliminating the extra humidity at the same time.&nbsp;</li>
  32. <li style="font-style: italic;">Controlling the climate
  33. in a commercial building requires three things: warm or cool air, a
  34. distribution method, and controls..</li>
  35. <li><span style="font-style: italic;">Packaged
  36. systems are all-in-one units, consisting of the compressor, condenser,
  37. evaporator, and fan coil. The thermostat is integrated. Packaged HVAC
  38. units are great for buildings that don&#8217;t have the room for bigger ones.</span>

  44. County, Cooke County, Denton County and Grayson County in the North
