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.

Homeowners: Here Are 3 Indicators That You Need To Replace Your AC Unit Soon

Nicole Jacobs

Homeownership comes with complex and sometimes expensive decisions. While most experts say that home upgrades can greatly increase the value of a property, it can be difficult to determine how and where to do that. Do you repaint your home or update your bathroom? The answer isn't always forthright. It becomes even harder when you have to decide whether you need to replace your air conditioning unit. 

If you're not an experienced AC contractor, it can be tough to choose between repairing or replacing your system entirely. Continue reading to learn the early warning signs that you may need to replace your AC.

1. Frequent issues that require expensive repairs

Continuous AC repairs can be inconvenient and expensive. To control the cost of repair, ensure that you have a repair cost cutoff point. This means that you will only replace your AC if the cost of repairs is more than the set amount.

But how do you determine that the cost of an air conditioner repair isn't worth it? If the cost of repair is half the price of a new unit or a major part of your equipment fails, it would be best to replace your AC. Yet, you may want to first discuss your options with a trained AC contractor and get an idea of the estimated lifespan of your old AC.

2. Changes to the square footage of your home

Air conditioning systems are designed depending on the size of the space they have to condition. This means that if you have a big home, you will need a big unit to cool your home more efficiently. Therefore, if you have recently made additions to your space, you will need to replace your current AC with a bigger one to meet the increased demands.

If you've just started your renovation project or you're planning to start soon, it's a good idea to talk to an AC contractor about your project to determine if your unit will handle the changes. This will help you prepare a budget for all upgrades needed and prevent efficiency problems later.

3. Cool air inconsistencies

When you enjoy the comforts of an air conditioning unit for the first time, the difference it makes to the air in your home is like night and day. However, if you notice that your AC fails to cool the air for a few minutes after turning it on, it could mean a serious mechanical problem or your ductwork is clogged. At this point, you should call an air conditioning contractor to determine the root cause.

If you note any of the above warning signs, your AC may be on its last legs. The first step is to talk to a trained AC contractor to get the unit checked.
