Installing APR Control at WMUR

Avoid Costly HVAC Callbacks

In HVAC Service, callbacks and warranty issues are an enormous problem and headache for HVACR contractors and service technicians. With the addition of the APR Control, you can eliminate callbacks on new equipment and improve performance of older/in-place equipment, saving you both time and money! Of course, contractors should always follow best practices when it comes to start-up and commissioning newly installed equipment to ensure proper operation. However, callbacks can be inevitable and are not necessarily a result of anyone’s failure to install the part or equipment properly. More often than you might think, callbacks and warranty issues are related to equipment problems.
Capacity Control with APR Control

Why Does DX Air Conditioning Need Capacity Control?

Everyday contractors, engineers, and building owners across the country turn to the ease of DX air conditioning for a variety of reasons. The challenge with DX systems is that they are oversized by design! This is due to the fact the cooling capacity (tonnage) of these systems are selected based on the space’s “design day” conditions. For those unfamiliar, a “design day” also commonly referred to as peak load conditions, takes into account the full ambient (highest outside temperature for the region) load, full building occupancy, all lights, computers and other equipment are on, occupant fresh-air ventilation, etc. The problem is that this “design day” rarely occurs. This means that the unit will be providing too much cooling capacity the majority of the time. Depending on where you are in the country, an oversized unit can have dire consequences for the indoor space and equipment.
