Rooftop Economizer CO2 | HVAC Control – This damper is part of a free cooling system for a rooftop economizer. It is part of an economizer damper system that allows free outside air cooling when the outside air temperature and humidity are ideal. This economizer also works on CO2 control so that if the CO2 levels inside the space rise above a set point the economizer damper opens allowing fresh outside air into the building while venting the air laden with CO2 to the outside.

Bacharach Combustion Analyzer Furnace Testing - The combustion analyzer is used to test gas and oil furnaces to make sure the combustion process is as efficient as possible. This multi-function HVAC test instrument can also be used to test spaces for carbon monoxide, test building pressure, all in addition to testing the combustion process of the furnace.
The combustion analyzer allows an HVAC technician to test the flue temperature, the amount of oxygen in the furnace flue gases, the amount of carbon monoxide in the flue gases, the amount of carbon dioxide in the flue gases, and the pressure of the flue. All these readings are necessary so the HVAC technician can make adjustments to the burner settings to ensure efficient combustion using the combustion analyzer. (more…)
HVAC Tip - HVAC Preventive Maintenance: Just like a vehicle needs preventive maintenance, HVAC systems need a regular maintenance schedule. Having maintenance performed on your air conditioning and heating systems now can help you avoid costly repairs in the future. Air Conditioning and heating preventive maintenance also pays for itself by making the unit more efficient, safe, and reliable. Often, a technician can spot a ten dollar part that needs replacing now where if it is let go and not replaced, can cost you hundreds of dollars more in the future. The old phrase is true, "pay me a little now, or a lot later." I see it every day. Basic maintenance on condensers and air handling units will save you money in the long run. If your local heating and cooling company offers maintenance agreements look into getting one for your home or business. Typically, companies offering maintenance agreements waive overtime charges for after hours or emergency calls and offer you reduced prices on parts. That is in addition to performing preventive maintenance twice annually.
