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.

Common Components Of A Heating System That Need To Be Repaired Or Replaced

Nicole Jacobs

When you turn on your heater during the winter months, you most likely enjoy the warm air it provides without thinking too much about how your heater works. In reality, a residential heating system is actually quite complex and consists of a number of components that work together to produce hot air. Unfortunately, since a heating system is complex, if one or more components cease to function as it should, your heater may not work properly. In most cases, repairing or replacing a faulty component of your heater will take care of the problem. Some common heater parts that may require replacement or repair include the following.

Air Filter

One of the most common causes of heater problems is due to dirty air filters. Heater air filters can become clogged with soot and debris, and when that happens, the heater has to run longer and more often. When this happens, components of the heating system can overheat and the limit switch can become damaged.

Heater air filters are one of the easiest things to replace -- in most cases, a homeowner can replace the heating system's air filter on his or her own. It is a good idea to always change the air filters in the fall before you begin running your heater and then check them regularly throughout the winter.

Damaged Blower Belt

The blower belt inside a residential heating system helps to ensure that the blower motor functions properly. Over time, the blower belt can become frayed or stretched out, which can cause it to move out of proper position.

When it comes to heater repairs, replacing a damaged blower belt is relatively inexpensive. One common sign that your heater's blower belt is in need of replacement is a loud squealing or screeching sound when your heater is turned on.

Ball Bearings

A residential heater system has several ball bearings that help hold other components together. When the ball bearings reach the end of their lifespan, they will need to be replaced promptly to prevent damage to other components of the heating system that can be very expensive to replace.

If your heater has worn out ball bearings, you will notice a distinct scraping sound. If your heater is making this sound, turn off your heater right away, and contact an HVAC repair company.

Malfunctioning Thermostat

Sometimes issues with your heating system are not due to the internal components. A number of heater issues can be caused by a malfunctioning thermostat that needs to be replaced. When your thermostat can no longer communicate properly with the heating system, your heater may not turn on at all, or it may continue to run until a room is much warmer than the thermostat setting.

If you need to replace your heater's thermostat, consider upgrading to a smart thermostat in order to make your heater more energy efficient. For more information, contact an HVAC contractor who provides heating repair services.
