If your air conditioning has gone out this summer, the one thing that you may have your mind on is getting an HVAC technician to your home immediately. If the air conditioning has gone out, you should call for HVAC services to come to your home as soon as possible so that there is no holdup. While you are waiting for your appointed day and time to arrive, you should get some paperwork in order so that there is no hold up once HVAC arrives at your home. Here are three types of paperwork that you want to have waiting on the table.

Model and serial number

Different air conditioning models will have different openings and will need different methods of service. In order for your HVAC technician to be able to tell which your machine needs, you should have the make and model number. The serial number is also important for some HVAC technicians. Some HVAC firms require the serial number so that they can be sure of the validity of the machine and to record any maintenance done to the machine. You can find this information online and in your purchase records for the machine. 

The age of the machine and where it was purchased

If you can, you should find the age of the air conditioner and the store where the air conditioner was purchased. This can make a difference, as some machines are eligible for discounts or freebies based on where they were purchased. Knowing the age of the machine will help the HVAC contractor determine if the machine is showing signs of usual wear and tear or if the machine is showing unusual issues for its age. This will determine the method of service for some HVAC machines. 

Prior maintenance records

One of the easiest things to do is for a technician to check up on the past work that was done if there are records. If a machine is suddenly going haywire, it could be that past work was faulty. Find all of the prior service records that you have and be sure that they are readily available for your technician. The HVAC tech can go over the service records, then take a look at the work and wiring that was performed. Your HVAC may be able to identify faults in past work and correct these so that your machine will remain in good working order.
