Q: Do you accept credit and debit card payments on a job site?

A: Yes we do. We accept all major cred or debit cards over the phone, point of sale or on a job site. (see our acceptable payment types on the store page). 


Q: Do you charge for your estimates?

A: No we do not. However, if more-than one estimate is requested for different phases of the same job, ONLY the first estimate is offered FREE. There will be a charge for any additional estimate requested but that charge is refundable via a rebate process if the job or a particular  phase of such job is contracted and completed by us or any of our affiliates or partners. 


Q: I recently bought an air condition unit but it said on the label 220 volts and all my outlet are 110 volts. What can I do to make it work?

A: The first thing is to find out whether or not you have 220 volts supply in your 'circuit breaker panel sometimes referred to as the 'load center'. If it has, then you may want to call an electrician to install a new line (outlet/ circuit) from the panel to the location of your AC unit. If it doesn't have a 220 supply, the second option is to use a step-up transformer rated to meet the load demand/ consumption of the AC unit. However, this is not a common practice in some local and may not be suitable for your situation; you may also need to consult a qualified electrician or let us know if you need further assistance. The next option is to, upgrade your meter service. This means you will be required to do some alteration to your existing wiring from the 'service meter' to your 'circuit breaker panel'. This will also require you to contact your electrician or contact us by either telephone or email.


Q: I saw one single listing site posting everywhere that, your company has no rating by them. Why are they doing that contrary to public record that, your company won the "Best Of Brooklyn Award for 2017"? I have known this company for years and I happened to know some of your customers and everyone speak highly of 4Ds T&D Inc. 

A:  This has been recently drawn to our attention by a few customers and we have seen it ourselves.  We would not name this 'listing site' here but they're are not our  affiliate, we do no business with them,  we have never advertised our business with them and have not listed our website with them in-spite their numerous request. 

Our public record and our many satisfied customers are the only credible source and recognized form of ratings.  Also, our rating do not depend on any paid advertising agency's determination, period. 


Q: I have a problem with three of our power outlets and I cant understand why nothing works when I plug them into the outlet. I used my tester screwdriver to check them and all the outlets lit up the tester, showing there is current in the outlets. This is crazy and why?

A: Tester screwdrivers are best used to give a general idea whether or not current is present in the circuit at that point of testing. It cannot determine the absent of an open circuit or the power status. You will need to use a voltage tester/meter to better diagnose a power problem. However, based on your description, it seems as though you have an open circuit that feed those outlets (faulty or broken line/cable/wire/connection).


Q: One of the circuit breaker is tripping very often and sometimes it takes a long time before it can be switched on back. What may be the cause?

A:  There're few things to consider here in order to make the correct diagnosis or determination -: (a) The circuit may be over loaded (b). The breaker is defective. (c) There may be a faulty piece of equipment on the circuit or (d) Faulty or defective wiring may be the cause. These are the most common causes and this will require some diagnostic skills by an 'experience electrical technician' [not all electricians are trained in diagnostic procedures so, if you're not sure who to call, we have expertise in these procedures] to get to the source of the problem and implement corrective measures.
