Install an HVAC and Keep Cool

The Australian summer can be super hot. If you live in Australia, you will want to make sure you can stay cool during the intense heat. I came to realise how important HVAC systems are when I moved into an apartment which didn't have HVAC. It was OK in the winter, but by the summer, it was terrible. I called in an HVAC contractor and asked them to install a new system. It was amazing what a difference it made. The contractor also gave me some advice about how to maintain the system. I hope this blog is useful to you.

Why Size Does Matter For Your Residential Air Conditioning System


Investing in the right system for your residential air conditioning will help you achieve climate control for your spaces and make your home more comfortable. Split-system air conditioning and central air conditioners are both excellent choices for residential air conditioning. For both options, proper system sizing is very critical.

Getting It Right

While central units are sized for servicing your entire home, split-system air conditioning systems are sized for the particular room or zone they serve. The best way to go about sizing your residential air conditioning unit is to first evaluate or calculate your load.

Contrary to what you may think, accurate load calculation for air conditioners takes more than just the square footage of the room, zone or home into consideration. Other equally important factors to consider include insulation of the zone or home, the orientation of the zone, the number of doors and windows in the house and the climate of the area.

Why Does It Matter?

System sizing will affect both the performance and longevity of your residential air conditioning system. A system that is too small will need to work continuously to keep up with your air conditioning needs. As a result of the strain on the system, it may fail prematurely, requiring repairs now and then. You may also find yourself needing to replace the entire unit long before the end of its average useful life. Thanks to the inefficiencies in your air conditioning system, you will also be looking at higher utility costs every month.

Bigger is not always better with residential air conditioning. Choosing a system that is too big will, first of all, be more expensive in terms of upfront purchase and installation costs. Secondly, your system will have short-cycling issues because it will be able to cool your spaces in a short time and so will keep switching on and off all the time. Short cycling will, over time, take its toll on the system, resulting in the need for repairs and replacement. Because the system runs for such short periods, it may also not effectively dehumidify your spaces, reducing your comfort.

Bottom Line

There is no one-size-fits-all solution for residential air conditioning systems. An expert will carefully factor in all the relevant factors when sizing your system. With a system size that is just right for your specific air conditioning needs, you can look forward to better efficiency, a longer lifespan for your system and less spending on utility costs and repair charges.
