Quality Air Conditioning Repair and Service

Are your present air conditioning systems proving increasingly expensive to run?

Are your air conditioning filters in need of cleaning/replacement?

Are your employees and/or customers feeling uncomfortable?

Or it may be the case that you are simply looking around for a new air conditioner repair and service contractor, perhaps to diagnose an existing air conditioning problem.

It pays to have your air conditioning properly maintained and serviced

  • A poorly-maintained system will cost more to run because it uses more energy
  • Uncomfortable staff become less productive or even irritable
  • And uncomfortable customers start to complain, leave early, and spend less

This is where Quantech Environmental can help, with a variety of air conditioner repair/maintenance packages available to suit all types of business.

We offer a wide range of services ranging from air con leak detection to basic preventative maintenance and aircon cleaning right up to fully-featured bespoke packages. To find out more, why not get in touch with us today?

Whatever your needs, you can be confident that we’ll be able to tailor an air conditioner service programme to suit your individual business and budget.

All service engineers fully trained and certified

All of our service personnel are comprehensively trained and fully certified on safe handling and disposal of the refrigerants used in air conditioning systems and, as required by law since July 2011, we hold a full F-Gas Company Certificate.

We are also registered and appropriately certificated through the Environment Agency in these respects.

All of our engineers are subject to our policy of ongoing training, and regularly attend a variety of air conditioning equipment manufacturers’ own courses to keep them firmly up-to-date with revised service and repair procedures.
