Does my generator purchase include a battery?

Generators ship from the factory without batteries to ensure that the freshest possible battery is installed at the jobsite; and some contractors will make the battery an additional purchase option. However, Princeton Air does not consider this to be an “option”, and therefore includes a battery with all generator installations - and makes sure it is the proper battery for your generator model.

How can I tell if my home has an IAQ issue?

Here are a few questions to keep in mind if worried about your home's indoor air quality:

  • Do you have symptoms that occur only when you are at home?
  • Is anyone else in your family experiencing these symptoms?
  • Are the symptoms season specific or time specific?
  • Have changes recently been made to your house (i.e. remodel or flooding).

If your answer to these questions is yes, we recommend checking with a doctor and contacting us or another qualified IAQ tester to find the source of the problem.

How do I know if it is more cost-efficient to repair my old air conditioning system or replace it?

Replace your system if it is more than 10 years old and only in average condition, it does not keep you as comfortable as you would like, it breaks down frequently, or you will be living in your home for at least five more years.

Repair your system if it is less than 10 years old and in good condition, your cooling costs have been acceptable, you’re pleased with your level of comfort, its performance is reliable, you will be moving within the next five years, or it is still under warranty.

How do I know what size system to install?

The experts at Princeton Air will be happy to come to your home or building and calculate your cooling and heating “loads.” They will then be able to recommend a system that is the correct size and model to meet your requirements. Please call us for more details.

How do I learn about local installation codes?

Code requirements for installing standby generator systems vary nationwide. That's why Kohler recommends having a factory-authorized dealer like Princeton Air install your system, since they are familiar with both local and national codes & can (almost always) avoid code issues with local inspectors.

How do your emergency services and live technicians work?

We have a service technician on-call 24 hours a day, 7 days a week. So you will always speak to a person, not a machine.

If you are calling to schedule a tune-up, we’ll put you on the schedule and confirm the date and time with you the next day during regular business hours.

How does a furnace work?

Heat is generated by burning natural gas or propane inside the furnace. This happens in the combustion chamber, which gets very hot. Air absorbs this heat in the furnace’s heat exchanger. Next, the blower sends the heated air through a system of ducts, and warm air circulates through the home.

How long do customers have to wait for service?

If we don’t arrive at your home on the day of your service, you can deduct $100 from your invoice. Guaranteed! In addition, we offer the options to schedule an 8 AM appointment OR provide you with a 3-hour time window OR schedule an appointment after work (until 7 PM) OR we can call you at work/page you before the technician arrives at your home OR schedule a Saturday appointment.

How long does it take to get an estimate?

Usually it’s only a matter of a couple of days. We can come out to your home or building at your convenience during the day or in the evening. To recommend the right size system for you, we do a lot of calculations. One thing we look at is heat loss, or the amount of heat your home or building loses in the winter. This is just one way we figure how much BTU “power” your heating system needs.

How much does an air conditioner cost?

There are many different factors that come into play when determining the cost of your air conditioner. When you buy a car for example, you just pick your amenities and it’s ready to drive away. But when it comes to AC, aside from the actual unit it also needs to installed properly first in order for it work. It’s a FREE estimate, no obligation, no high pressure.
