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.

How To Repair A Defective Drip Pan

Nicole Jacobs

The air conditioner drip pan catches moisture that is created through condensation. The AC comes with both a main drip pan and an auxiliary drip pan. Because the main drip pan is difficult to access, you'll need to replace the much more accessible auxiliary pan when there is a hole in it.

1. Turn the AC Off First

Always shut your AC unit off first before you replace the drip pan. While your AC might shut off on its own when you remove the cover, it's safer to shut the power off and flip the switch to determine if the AC will turn on or not. 

2. Inspect the Drip Pan

Inspect the drip pan to find out if the drip pan is connected with screws or clips. If you cannot find any fasteners that hold the auxiliary drip pan to the AC, you will not be able to replace the drip pan and you may need to contact an AC repair specialist.

3. Detach the Drip Line

The drip line needs to be removed from the drip pan before the pan can be removed. This can be done using a wrench or pliers. Then, remove the clips or screws and slide the drip pan out. Do not touch the water because it could harbor bacteria and might also contain mold. 

4. Replace the Drip Pan

Dispose of the old drip pan. Install the new drip pan and replace the screws or clips. Then, you can put the hatch back in place and turn on the AC unit. 

Use a Self-Sealant

If you are not able to replace the drip pan, you can place a self-sealant over the pan to seal the problem area. You will want to add sealant to both sides and you will want to give the compound time to harden. This will give the sealant a much better bond. If you are struggling to get the sealant to stick to the pan, you might need to sand the pan with sandpaper until the sealant is able to stay in place.

Hire an AC Repair Technician

If you're not confident in your ability to replace the drip pan for your AC unit, the best option is to turn to an AC repair specialist. Then, you'll not only have your drip pan replaced, but you'll also be able to have your AC unit inspected for any other problems you might be facing.
