Learning About Commercial HVAC Systems

Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.

Step One In Any Furnace Repair Process: Turn It Off

Isaiah Chapman

At some point in time, all furnaces need furnace repair services. You may be able to do some repairs yourself if you have a little experience in this area. However, most furnaces need an HVAC technician to fix what ails the furnaces. You can, however, do the first step in the repair process, regardless of what type of furnace you have. You can turn your furnace off, and here is how to turn off each kind of furnace before your repair technician arrives.

Electric Furnace

All electric furnaces have a light switch on them. Look all the way around your furnace for something that closely resembles a light switch. This is the electric furnace's on/off switch. When you find it, you should see it switched up to the "on" position. Switch it down to the off position. 

Oil Furnace

For an oil furnace, you not only have to switch off the electrical part, but you also have to turn off the oil feed. After you turn off the electricity that feeds the burner part of the furnace, follow the fuel line to a valve handle. Turn or crank the valve handle to close the oil feed line. This prevents oil from moving forward through the line and oozing out the burner. The highly flammable mess is prevented, and your heating fuel is conserved until the furnace issue is repaired.

Propane Furnace

Shut off or remove your propane tank. If you can easily remove the propane tank, that is better than just turning it off. The furnace may click on, but without the propane, it will not continue to function, nor will it produce heat.

Boiler Furnace

Oddly enough, most residential boilers are just like electric furnaces. They, too, have light switches you can flick to the off position to turn off your boiler. It is a good idea to turn the boiler off at least a half hour to an hour before the repair technician arrives to reduce the risk of injury.

Natural Gas Furnace

A natural gas furnace should have a valve to shut off the flow of natural gas to the burner. You need to shut off the gas prior to repairs because of the dangers of inhalation and explosion. Find the fuel line and look for the safety valve. Flip or turn the safety valve to the off position BEFORE you turn off any electricity to this type of furnace to avoid a buildup of natural gas within the space around you.
