HVAC Energy Efficiency, Cont’d

Wednesday, April 23rd, 2008

In these times of high-energy prices, it’s a natural to think about your heating and cooling systems’ operational efficiency. Most home and business owners understand the basics - change air filters regularly, have the oil burner cleaned annually, etc., but few understand how systemic - incorporated into the design and installation - issues affect the amount of energy used.

In my estimation, roughly 40% of systems consume excessive amounts of energy commencing the day they were first turned on. Usually because the design was inept and poorly thought out, and/or because the installers cut corners by using too small a pipe or duct diameter, inappropriate controls were chosen, or the equipment was too large in capacity to begin with. For example, I ask this no-brainer of a question: Will a tractor trailer truck transport you to the grocery store to do your weekly food shopping and back? Of course it will, but at what expense for fuel? Who needs to drive there in such an expensive vehicle that consumes so much fuel, unless, of course, you are shopping for a National Guard Battalion? Well, that’s analogous to having too large a boiler or air conditioning system in your home or place of business. Another good analogy is that if your hvac equipment is too large, then it will perform too quickly and soon shut down, then come back on, then shut down again, then come back on…you get the idea. That example compares to city driving vs. highway driving. Once your car overcomes inertia and is up to speed on the highway, and cruise control has been set, it requires much less fuel than if the car was constantly stopping and going and repeatedly overcoming inertia.

These are simple examples of poor fuel economy, but with 28 years in the business, I can demonstrate endless others. Suffice to say, if 40% of all systems’ energy consumption can be reduced, then is yours among them? Protech can evaluate your system for as little as the cost of one hour of labor - $85. You could save that amount many times over if you take corrective action by allowing us to make changes to your poorly designed or installed hvac system(s). Should you become aware of your hvac system efficiency?
