Domestic - J & S Airconditioning and Heating

At A & C, We understant that having a reliable, efficient home Heating and Cooling system is extremely important. Rising Gas prices, the ever changing economy is affecting most. This is why we are only use brands that meet our standards. We are strong advocates for do it right do it once. Ask us how we can provide you with a system that best suits your family and lifestyle.

Volume Domestic

We understand that the volume market is tricky. We know timelines are tight and margins need to be met. We work with an array of builders to provide both a fast, reliable service that is also cost efficient. We work closlely with the likes of Braemar, Rinnai and so many more to ensure the units are cost effective whilst also reliable.

The first step is telling us about yourself, how many homes you build, what type of homes your building and where are you building, this way we can get a good understanding of you as a client and how we can assist you. Based on this information we can provide you with accurate set pricing to improve budgeting. We will guide you in the right direction towards a system type and manufacturer who will support best.

Custom Homes

Whether your builing your dream home or building the dream for your client, we have you covered. This can be one of the most difficult aspects of Airconditioning. when custom building the dream you expect nothing but the best. building a close working relationship with our clients throughout the initial stage gives a more in depth understanding of your lifestyle. This helps when chosing the right system, as what may work for some may not for others.

No matter the budget, no matter the requirement, pointing you in the right direction is our specialty. From a builders perspective nothing is more stressful than an unhappy customer. With us we can assure you this will not be the case. Contact us, send a copy of the plans with some background information and we will educate and provide you with the right system.
