Before a visit from your professional Armstrong Air dealer, it may help to review this
list of questions. You could end up saving time and money.
- First, review our troubleshooting section to see if the problem is
something you can handle without calling a serviceperson.
- Make a quick inventory list of where all the units in your system are located-including indoor unit, outdoor unit,
circuit breaker, utility meter etc.
- Obtain the model numbers of all your cooling and heating units.
- Know basic information about your problem: what symptoms have been going on, what seems to trigger the
problem, how long ago your problem began, etc.
- If evidence shows that your air conditioner or heat pump is
frozen, switch it off prior to the technician’s arrival so it may be serviced properly.
- Be sure an adult, 18 or over, is able to legally allow entry into your house.
- Often technicians will confirm an appointment prior to arrival. Please have a phone easily accessible.
- If your house is rented, speak with your landlord in advance.
- If the unit is located in a closet or an attic, or is blocked by a piece of furniture, do your best to have
the unit easily accessible to the dealer.
- You may need to make a payment to the dealer, so find out what method of payment is preferred.
