"Vitt was very responsive while we investigated alternatives, and provided prompt answers to our many questions. Once we made the decision based on Vitt's good price and excellent equipment, they began the very next day and installed three complete HVAC systems (furnaces, coils and outside units) in one day. Very professional and superior work. We highly recommend Vitt."

"Paul Peterson is a knowledgeable and friendly guy.? Arrived at my house 15 min. prior to apt time.? Paul reviewed the areas I thought were the worst, and showed me leaks in the house I would never have thought of.? I was not surprised at the outcome of the energy audit, but I was surprised by the price.? It was less than I thought it would've been."

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Common warning signs of an overloaded electrical panel or meter box include frequent circuit breaker tripping, flickering or dimming lights, scorch or burn marks, and a burning scent coming from the panel. A circuit breaker trips as a protective measure to prevent overheating and potential fires. If you observe any of these signs, turn off the affected circuit breaker and move some devices to a different circuit. If the problem persists after turning the breaker back on, you should contact a professional electrician to resolve the issue.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency. 

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
