Designing Heating and Cooling Systems in Large Buildings

Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.

Probable Causes of Your Furnace Shutting Off

Nicole Jacobs

When you turn on your heat, you expect your furnace to provide warm air. However, there are instances when furnaces do not operate as intended, and it can be a frustrating situation. One phenomenon that can occur is when a furnace shuts off repeatedly. Several things can cause this to happen. The following points represent a few things that could cause this to happen.

Clogged Filter 

This is one of the main reasons that furnaces shut off repeatedly. Some homeowners forget to change their filters. This can result in severe clogging. Many modern furnaces have enhanced features. Some of them are safety features. If these furnaces detect that there is restricted airflow, they might shut off. Inspect your furnace filter. If it appears dirty, change it. This could correct the issue. If it does not, you might need to get an HVAC contractor to inspect it and perform furnace repairs. If you are forgetful or do not like the idea of buying filters from time to time, consider getting a reusable filter that you can wash and reuse. 

Furnace Size

If you recently moved into your home and this is your first winter, your issue could be related to the size of your furnace. There is not a one-size-fits-all furnace. Proper sizing is important for many reasons. This is why it is best to get a professional furnace installation. The calculation for the size of a home and other factors need to be taken into consideration. Granted furnaces that are too large will heat small spaces quickly, then they will shut off when the thermostat registers that the temperature has been reached. The heat will continue to cycle on and off. It might be frustrating because, despite the fast heating, the heating system will cycle at short intervals. 

Flame Sensor Issues

Every component of furnaces has a purpose. Flame sensors can cause furnaces to act erratically when the sensors cannot detect flames. If a sensor is dirty or corroded, it cannot detect a flame. The safety feature in most furnaces will stop the gas flow if a flame is not detected. This safety feature prevents gas leaks. Routine furnace maintenance includes cleaning components of furnaces. If there are corroded or damaged components, they would be replaced. 

You can contact residential furnace repair contractors to diagnose the problem. It is best not to assume that you know what is wrong with your furnace. Routine maintenance can improve your chances of having a furnace that does not need repairs.
