What is Home Performance Contracting?

The main goal of home performance contracting is to improve a home's comfort, safety, health, durability and energy efficiency. This is accomplished by using the principles of Building Science, looking at the house as a whole, and examining the relationships between all of your home's systems. We focus on all the systems within the building envelope, which include heating, ventilation and air conditioning equipment as well as the habits of the home's occupants.

The home performance improvement process starts with a comprehensive home assessment that is used to identify problem areas and pinpoint the source of any issues. From the assessment, we are able to provide a range of improvement options from easy do it yourself jobs to more in-depth retrofits. Once our work is complete we re-assess a home's performance to ensure that all of the improvements are functioning properly.

What should I do if my heating system doesn’t work?

Before you call or e-mail us, go through the troubleshooting steps below to make sure a service call is really needed. It will save you the cost and inconvenience of an unnecessary service visit, and will ensure our technicians are working where they are most needed.

  • Make sure the thermostat is set above room temperature or in the “heat” position. If it’s a digital thermostat and the display screen is blank, you either need new batteries or the power supply has been interrupted.
  • Check for a tripped circuit breaker or a blown fuse.
  • Look to see if the power switch for your heating system is turned on. Sometimes, these get turned off accidentally.
  • Check your tank to see if you have heating fuel.
  • If you have an oil heating system, press the reset button on the burner relay—ONCE ONLY. If your system doesn’t start after you push the reset button the first time, do not push it again. Pushing this button more than once can cause your heating system to “flood.” Too much oil will get pumped into the combustion chamber, resulting in a lengthy and costly repair.

If at this point you still don’t get heat, call Princeton Air immediately.

When a service technician arrives, let him know everything you did to the system before he begins working on it. You should also let him know if anything out of the ordinary happened, like an unusual noise, a strange smell or smoke.

In many cases, this will help the technician find the problem—and get your heat back on again—faster.

What size generator do I need for my home/business?

For the most accurate, detailed estimate, we strongly recommend that you contact us, your local KOHLER Generator dealer, and schedule a no-charge site visit with one of our Generator Specialists; we can analyze your home and/or business’ electrical load and lifestyle/workstyle needs, and then specify & install your generator system. However, if just getting a rough idea of what size your home or business might require is enough, you can use this Sizing Tool to get an idea of your power requirements.

What size transfer switch is best for my generator?

Princeton Air, your local authorized KOHLER dealer, will perform an onsite analysis to determine which generator and transfer switch combination offers the best solution for your home or business.

What’s the difference between a regular installation and an energy-star rated qualified installation?

A regular installation (or a change-out) is normally what people get when you’re bidding jobs, which includes the replacing of your equipment, takes 1 day, the installation turns it on, Freon levels look OK, they’re done. An ESQI follows recommended industry standards by the Air Conditioning Contractors of America, starting with load calc and you measure everything. Most houses across the country deliver less than 60% of what you’re paying for in terms of BTUs. If you have a 5 ton, you only actually get a 3 ton. So you’re wasting 40%.

Why does it cost so much to run an air conditioning system?

Air conditioners run on electricity, and electricity is the most expensive energy source. Converting fuels like coal or natural gas into electricity is inherently inefficient. What’s more, much of the original electricity generated at the power plant is lost during transmission over power lines. So, according to the U.S. Department of Energy, by the time it reaches your home, electricity is only 33% efficient on average.

The good news today is that air conditioning systems are much more energy efficient than they once were, and things are improving all the time. Another important factor is design—if your AC system is not carefully planned to meet the cooling needs of your home, it will run less efficiently than it should. Princeton Air’s takes great care in evaluating and designing efficient systems, and we can recommend high efficiency equipment from quality manufacturers like American Standard.
