Please note we are extremely busy. Current wait times for installation are 2-3 weeks for split systems and 6-7 weeks for ducted systems.
If you're thinking of adding an air conditioner before summer then getting a quote sooner rather than later would be advisable.


Penair has spent the past 20 years working with clients in Dover Heights and other Sydney suburbs, to offer them the best airconditioning and heating solutions. Excellent customer service has always been our priority, which is why we’ve grown to become a trusted airconditioner installer and provider of maintenance and repairs.

As an official Daikin dealer, we manage installations of all sizes and budgets. Our technicians, however, repair services on all brands of air conditioners.

We offer annual maintenance programs to our clients in Dover Heights to ensure their systems remain working efficiently year after year. It’s worth noting that airconditioning warranties require the following maintenance to be done annually to remain valid. We do this and so much more when we service your unit:

  • Cleaning/replacement of the air filters and outdoor unit
  • Unclog condensate drain
  • Replacement of batteries
  • Application of corrosion protection
  • Checking wiring and electricals
  • Making sure there are no leaks


Our friendly team will help you find the best heating and cooling system for your property and needs. Some of the factors they will investigate on your property is if you have pets, the number, and size of rooms and the location. It’s important that clients are provided with the correct size solution for their homes or businesses – we go the extra mile to calculate what your needs are. A unit that is either too big or too small for a space will not give you the comfort levels you want.

We install Daikin products as we consider them to have the best air conditioning products on the market, with an extensive range and the best back-up, including a 5-year warranty. Options include:

Split System Air Conditioners

Recommended if: clients want to cool or heat a specific area of a home. Inverter and non-inverter air conditioning systems are available.

Multi-Split Systems

Recommended if: the roof and underfloor space cannot accommodate a ducted system. It allows the client to control the climate in different rooms.

Ducted Air Conditioning

Recommended if: the client wants to condition the air in more than one room or area, with sizes ranging from 5kW to 25kW available.

VRV Systems

Recommended if: the client wants a bespoke solution with various indoor units and control systems connecting to one or more outdoor units.

The Daikin VRV Systems are primarily used in luxury residential homes because of their versatility. Contact Penair if you are looking for a bespoke design for a VRV air conditioning system. We will connect with your builder and architect, review plans, and provide a detailed quote.


When dirt and grime build up on an airconditioning unit or clog up components, the system takes strain and begins to work less efficiently. This leads to increased energy usage and can ultimately affect the lifespan of the product. Ignoring maintenance will make your warranty invalid. Penair recommends you clean and services your unit twice a year to ensure that pollutants or allergy triggers are dealt with, such as cleaning the air filter.
