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.

Five Signs That You Need AC Repair
Nicole Jacobs
Don't be caught in the heat this summer. If you are having any of the following five issues, it is time to call an AC repair tech for more help.
1. A Spike In Your Cooling Bill
If your energy bill goes up more than you expect it to, then the culprit could be an AC issue. Problems like short cycling, running longer than necessary, and poor energy usage are things that can sometimes be remedied with a minor repair. Older units that are at the end of their service life may also use more energy than you like, which may indicate that it is time to install a new unit.
2. The Unit Makes Odd Sounds
Other than the gentle whoosh of air and the occasional popping noise from a duct, an AC unit should be relatively quiet. If you hear noises like rattling, squealing, or grinding, then there is an issue with the unit. Grinding and squealing noises, for example, may indicate that the compressor is failing or that something is wrong with the fan assembly. The sooner you call for repair, the more likely that the problem can be fixed before major damage occurs.
3. Warm Air Is Coming From the Vents
No one wants their AC to stop cooling during a heatwave, so if the air doesn't seem cool enough, then call for a repair as soon as possible. Warm air can indicate a thermostat failure, a refrigerant leak, damaged evaporator coils, or issues with the compressor. These issues, such as a bad thermostat, can often be repaired, although in some cases, it may make more sense to simply replace the unit.
4. Water Is Collecting Around the Unit
There will always be moisture coming from your air conditioner thanks to condensation, which is why most AC units are equipped with a condensate line and drain. If you are finding puddles of water, though, you need to have the unit looked at. Clogs in the drain line are a common cause of collected moisture, but other issues, such as a unit that is freezing and thawing, could also be the culprit.
5. Airflow Seems Weak
Sometimes a unit powers on and even blows out cold air, but the airflow seems weak. This can be indicative of a problem in the unit, such as a failing fan motor or issues in the ducts, such as a loose or leaking duct line. A technician will need to trace the problem to its root so a repair can occur.
