transitions for efficient fan operation, relevant supply duct design, targeted air destination and equipment set up are all factors for acceptable installations. Short cuts anywhere in the installation process can be costly. C. Deliver the performance the nameplate claims; Engineers that design air conditioning systems understand how to move air through the system and provide the proper amounts of heat or cool to the space regarding equipment size. We often impede performance by installing the equipment in the wrong space with inappropriate duct or too small air intake. Most often we install equipment leaving fan and accessory settings at default settings. 80% of the time default settings are wrong due to the abundance of condenser and evaporator pairings. There remains a misunderstanding on meeting static pressure requirements. Do not speed up or slow down fans to make the appropriate static pressure. Use the tables the manufacturer provides to set fan speeds and if readings are out of range make appropriate adjustments to return or supply side of the duct system by increasing or reducing sizes to adjust cfm. When static is above .15 on the return, increase intake size and /or improve filter efficiency. Return air and filters still provide the number one roadblock to performance. Supply plenums need care in design to be sure room temperatures are uniform and air flow is evenly distributed while appropriately sized for cfm. Transitions with no spacing or duct modification can leave filters ineffective and evaporators starved for refrigerant

and an overall failure to move heat appropriately and efficiently for the life of the equipment. By sizing different components correctly, we can speed up or slow down air as we wish, while providing adequate cfm delivery. With a little practice, static pressure becomes a valuable tool for insuring efficient air flow.

While all the prior information is a requirement for a quality installed system, there are other points to be made in general to support your business. Successful companies practice these points on a regular basis. D. Value your company’s ability to serve everyone; Give your customers several ways to contact you. As much as technology is a part of our workday world, there remains segments of the population, for whatever reason, that do not have the email, WIFI or other communication tools. Answering the phone with a live person is still a requirement. If the phone is not answered, the customer will move down his or her referral list and try another number. When the staff member assigned is not answering the phone, they can answer emails and provide virtual assistance for the company. Some customers, especially repeat customers, like a fillable calendar. That makes it easy on everyone. Still others have questions they need answered live or
