Repair or Replace?

Service Recommendations for Post Irma and Harvey Flooded A/C Units
by James Bowman, National Technical Manager–HVACR, RectorSeal, LLC.

The wake of Hurricane Irma and Harvey left thousands of residential air conditioning systems flooded throughout regions of Florida, Georgia and southern Texas and Louisiana.

Now, hundreds of HVAC service companies are facing decisions of restoring or replacing those air conditioning units. Not all properties have flood insurance. Therefore, many property owners are faced with prioritizing repairs on a very limited budget or even through charity and government assistance.

Flooded A/C units don’t always mean replacement, because there are various degrees of damage. If a service tech has a chance to save a mildly-damaged unit or simply replace a component, it might be a tremendous benefit for a flood-ravaged homeowner already facing tens of thousands of dollars in other residential construction material replacement costs. A quick fix with the strategy of later replacing the unit could also be beneficial to homeowners attempting expedite the drying out a flooded home’s interiors.

Therefore, the following is a service tech guide with tips for determining whether or not to salvage a flooded unit. Obviously, the floodwaters must have receded, power must be restored to the home, and all electric to the unit shut off.

PRO-Fit™ Precision Flaring Kit VS. Traditional Flaring

The next generation pipe flaring tool for copper and aluminum tubing used in air conditioning and refrigeration work.

PRO-Fit™ Precision Flaring Kit produces tubing flares in just seconds without splits, blemishes and burrs that cause leaks.

The kit consists of five bell-shaped, color-coded, size-inscribed flaring bits designed for 1/4, 3/8, 1/2, 5/8 and 3/4-inch (6, 7.5, 12, 16, 19-mm) tubing. The flaring process requires just seconds to complete using a (minimum) 12v drill or impact driver. The spinning bit forms the tube opening into a flare, without splits, burrs, blemishes or uneven edges that typically cause flare fitting connection leaks.

BTUs explained? (Simply)

I’m 18 years old and going into my fourth week of college for HVAC. So far we have talked about states, matter, the components of refrigeration, OHSA etc. I am understanding all of that slowly, I still have some trouble with it but I’m slowly absorbing it.

However, when my professors talk about BTUs, I am at a loss. I understand that it is a way to calculate heat and that it stands for British Thermal Units but that’s all I can understand. When I try to read my textbook about it, I get confused because it goes so in depth.

Can someone please help me? – NostalgicDuck

The simplest explanation is the definition. It’s the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. – Zackhood

So if I had a pound of water sitting at 70° F, if the temperature was raised to 75° F that would be 5 BTUs? – NostalgicDuck

I think he got it. By jove he got it! – toomuchpork
