A good leak detector is a big investment and one of the more important tools a tech has on the truck. One thing that I have learned is that with leak detectors care, maintenance, and testing is a huge part of finding leaks the first time.
When installing or repairing a refrigeration system, technicians should look for opportunities to slightly modify the system (without changing its design) to make it more serviceable.
Several of the boots-on-the-ground HVACR guys had some opinions on why preventative maintenance is important, why it’s so often overlooked, and what could be done to help the cause.
The homeowners of a medium-sized house complain of reduced airflow coming from their registers during the summer. Their air conditioner is a 4-ton (48,000 Btuh), R-22 split system with the A-coil in the plenum of the furnace located in the basement. The evaporator has an orifice for a metering device, and the condensing unit is located on the east end of the house.
Potential customers are out there, and they all have equipment that needs maintenance, so how can contractors best encourage them to book an appointment? Here are a few strategies to keep repair technicians busy during the time between Thanksgiving and New Year’s Day.
Bob and Tim are on a service call with an aggravated customer. The customer explained to them three different service companies had been out to her house this summer and all of them told her that she had a leak they could not find.
Bob and Tim are looking at a system that has a frozen evaporator coil. The system is in a home. They are talking about what has happened to the system and what to do about it.
If I owned a nice Italian restaurant and had a finicky soap pump in the men’s room, I’d definitely swap it for a good one. I mean, they charge enough for the food in this place. How much could a working soap pump cost? And how cheap were these people? Gosh, talk about leaving a bad impression.
