Service and Maintenance

An evaporator can be cold but inactive, causing warm refrigerated space temperatures.

While all the technical principles I learned from Rob Falke were valuable concepts, the most beneficial lessons I learned from him were about life.

The condenser is the most underrated component in an air conditioning or refrigeration system.

HVACR contractors can offer customers a solution to keep refrigerant costs down: reducing and eliminating leaks. That’s where better brazing comes in.

As the HVACR industry transitions away from HFCs such as R-410A to alternative refrigerants that are mildly flammable (A2L), it is not surprising that those who will be handling – or teaching about -- these new products have a lot of questions.

Homeowners should be proactive and schedule regular maintenance check-ups, which can be made easier with service agreements.

As the old saying goes, an ounce of prevention is worth a pound of cure. This is especially true when a replacing a thermostatic expansion valve (TXV).

Is it time for our industry to consider using pascals for static pressure measurements? What would the transition from inches of water column to pascals look like and how hard would it be?

If you are a plumber or a trade professional who actively promotes the use of high-efficiency, condensing equipment, you should be equally energetic in treating discharge coming from this equipment with some sort of neutralization.
