Why HVAC-R Equipment Fails
When heating, ventilation, air conditioning, or refrigeration (HVAC-R) units fail, your business can be left scrambling to get a maintenance or repair company to mitigate the losses. Coral Canada Wide has been offering HVAC repair and replacement services locally, regionally and nationally since 1992. Our experience allows us to be able to identify a problem and set to work, resolving it quickly. If your equipment fails generally it falls under one of these top reasons:
Dirt
Dirty condensers, evaporator coils, and control panels can cause several subsequent problems. Including cracked heat exchangers, seized blowers, seized condenser fan motors, and damaged compressors.
Very dirty and plugged condenser coils inhibit air flow through the outdoor (condenser) coil. This leads to an increase in head pressure until it eventually overheats. The compressor’s safety device eventually turns the unit off temporarily before it cycles on and off, still trying but unable to provide cooling. All this causes immense stress on the compressor, which increases power consumption, reduces compressor life expectancy and finally causes failure and an expensive repair.
A defective outdoor (condenser) fan motor has the same effect as a plugged coil.
Filters
A poor-quality filter or infrequent filter changes can be detrimental to a system. Often this will lead to the same issues seen by having a dirty system. Dirty and plugged filters inhibit air flow through the indoor (evaporator) coil. This causes a reduction in suction pressure until it eventually drops below 0*C, turning the e-coil into a block of ice. As with a plugged condenser coil, the compressor’s safety device eventually turns the unit off temporarily before it cycles on and off, still trying but unable to provide cooling. Again, this causes immense stress on the compressor, which increases power consumption, reduces compressor life expectancy and finally causes failure and an expensive repair.
A broken or slipping fan belt or defective indoor (evaporator) fan motor has the same effect as a plugged coil. Also, with the compressor off, the excessive ice melts from the e-coil, and the drain pan often overflows which leads to annoying and/or expensive water damage.
By installing a better filtration system, you can not only improve quality, but you’ll also extend the life of the unit and see reduced energy consumption.
Refrigerant Issues
There are nearly as many types of refrigerants as there are makes of equipment. It can take time to find the correct one for your unit. Coral Canada Wide recognizes the benefit of minimizing the variety of refrigerant to simplify the process for our clients. By having uniformity, we can expedite repairs because our service personnel always have it stocked.
Contactors & Control Wiring
Contactors, a moving part in the control circuit, can be affected by dust. Without consistent maintenance control, wiring can turn into a costly fix if your service person bypasses the control unit to resolve the issue.
Belt Sheaves, Drives & Bearings
Eventually, all systems will require replacement parts or repairs. If the belt sheaves, drives, and bearings are left unaddressed what could have been a timely, minor repair can become a more expensive repair in the future.
Tampering
Frustration and a desire to save money will lead to some people trying to ‘fix’ a problem on their unit. Tampering commonly results in compounding the initial problem. The result is more time and money spent than if a certified HVAC/ Refrigeration specialist were called in the first place.
How Coral Canada Wide Mitigates Your Risks
Another common reason equipment fails is due to code violations. Over the life of your HVAC-R equipment, previous contractors may have completed repairs that didn’t fall under the current code specification. Part of our mandate is to have our HVAC technicians go through continuous training. By doing so, they to stay up to date on the different code regulations to ensure all work follows the guidelines required by law.
As with any piece of equipment, there will be a time when the cost of frequent repairs no longer make sense. Coral’s mechanical journeymen are equipped with the best tools, knowledge, and skills to be able to evaluate those life cycle costs. This allows them to identify concerns early and provide clients with time to budget and prepare for retrofit or replacement.
In some cases, poor HVAC design can be the root of an equipment failure. We will assess the equipment, and after reviewing the design and/or application, clients are presented with recommended modifications to consider.
Predict Upcoming Repairs & Replacements
The overall best way to deal with HVAC equipment failure is to have a maintenance program in place. A program will provide clients with an opportunity to ask questions of the service technician. It also gives the technician a chance to become familiar with the equipment, its performance, and history, all of which can be readily reviewed. This familiarity is critical to understanding the full scope of operations and providing consistent care over the life of the unit.
