Naveen and his crew were on time, very professional in their work and installations went without a hitch. Also gave good information on what would work in my situation. Had reversible AC for a couple of weeks now and is excellent.

The team at NK is professional and friendly and managed to remove my old ducted air con which is over 17 years old in an awkward position above the laundry room in between two levels, and install a new Daikin ducted aircon which is much quieter. Another company said they could not do the job because of the tight air con location They also take care in keeping the area tidy before leaving, and Naveen also helped me put one of the light bulbs which was hanging by the wire back into the ceiling light socket.

Naveen and Surjit were very convenient to deal. Very professional prompt and genuine. They assisted us with the air conditioner repair on a very short notice. Turned up on time and fixed issues in prompt time and cleaned up after themselves. Highly recommended.

What are the consequences of not getting regular air conditioning services?

Skipping out on regular air conditioning services in Melbourne can lead to many issues. Your aircon might not cool as well, could start making strange noises, or even cost you more money because it’s working harder than it should. Without check-ups, small problems can grow into big ones, and before you know it, you might need major repairs or a new aircon way sooner than expected.

How can I tell if my aircon needs service?

You’ll know it’s time for an aircon service in Melbourne when your unit starts acting up. If it’s not cooling your room like before, making odd noises, giving off strange smells, or your electricity bills are creeping up for no clear reason – these are tell-tale signs. It’s like your aircon is saying, “Hey, I need a little help here!” That’s when you call in the pros like NK Air for a service check.
