In earlier blog posts we’ve noted that there are interdependencies between all the steps of the design process. The quality of the load calculation affects the quality of the information we use to select equipment. That in turn impacts the quality of the duct design. In today’s homes those same interdependencies exist among the structural, mechanical and service systems that make up the home. How these systems work together has become more important as homes are built tighter and with higher insulation levels to improve energy efficiency.
Heating, cooling, ventilation and control of indoor moisture also requires greater attention to detail as home efficiency improves. It is no longer unusual to be called out on service calls by the homeowner who believes there is something wrong with the HVAC system, when in fact; the source of the problem is structural in nature. More about that phenomenon in future posts.
Our industry has a tendency to overlook the importance of the installation technician. Many times, these are the folks with the least experience in the industry. Conversely, just ask any contractor who has an experienced installation technician on their staff and you’ll find out just how important that technician is to their business. Chances are you’ll hear several examples of how many times that experienced installer has saved the day. Here’s why.
Unlike most of the very reliable, high tech electric and mechanical devices we can walk into the store and purchase today, heating and air conditioning systems come with “some assembly required.” The environment within which that occurs sets the stage for how reliable that system will be, whether it will deliver it’s rated capacity, efficiency and energy savings, the frequency with which service calls will need to be made, how comfortable the customer will be and whether or not it will last it’s expected lifetime. Our perspective at Real World HVAC is that “we have just one chance to get it right.” And that chance to get it right occurs during the installation process. And that’s why experienced installers are worth their weight in gold.
The next several posts are going to showcase how we frequently miss those opportunities to get it right. Stay tuned.
