5 MOST IMPORTANT THINGS TO CONSIDER WHEN UPGRADING YOUR AC UNIT

Real estate is on a roll in the UAE, and here are some things we’ve learnt. 1) it’s not just developers cashing in. According to a YouGov survey, it is now more common for even high-value property deals to be done via individual sellers as, incidentally, 22 per cent of the 45-plus age group plan to retire and settle here. 2) Sellers aren’t wasting any time. With demand outstripping supply to the tune of 15-35 per cent value increases across freehold areas (recorded during 2021-22), some 52 per cent of Dubai property owners are said to be considering selling up in the next 10 months.

Where property sales go, home improvements flow. Whether in pursuit of a quick ‘flip’ or end-user comfort and security, this year 83 per cent of property buyers have proceeded to make significant improvements to their purchase, with 15 per cent spending over Dh500,000 on high-end renovations. And there’s the rub. Custom kitchen cabinets and fancy floors are nice to have, but if the HVAC wasn’t properly replaced, or was never considered in the first place, no amount of stylising is going to compensate.

If there is one thing you need to get right from the get-go in Dubai, it is robust cooling and air flow.

Here are 5 things to consider…

1. Do you want to make energy savings?

A 2022 UK survey revealed that 39% of homebuyers consider energy efficiency to be an important factor in their decision to purchase a particular property. This is likely to be at least as significant in the UAE, when you consider the cost of upgrading your AC unit over the long hot summer months.

Most villas in Dubai utilise a traditional split AC system where half is on the roof, half is placed indoors, and it cools using gas. That’s the basics covered. Now, you have 2 options when it comes to your unit type, and only one will significantly reduce your DEWA bills.

Everyone is familiar with a conventional AC unit. The compressor is either ‘on’ or it’s off. It goes from zero to 100% with nothing in between and the compressor switches off when the desired temperature is reached. When the thermostat recognises the temperature rising, the compressor goes back to 100% and away we go again.

An inverter system is a new way of operating things. First, it runs at 100% power to cool the room as quickly as possible and turns off in the same way as a conventional unit. Then things get interesting. When the temperature rises even slightly, let’s say to half a degree over what is desired, it goes, you know what? I don’t need to run at 100% to get the temperature down half a degree. So, the compressor will utilise only 20% of its power. Suddenly your electricity bill is reduced dramatically, with manufacturers claiming by as much as 40%. Obviously, the more you use your AC, the more you are going to see the energy benefits. This is why, in hot climates like Dubai, an inverter AC is typically regarded as the smart option.

2. Or do you want an easy install?

Consider your timeline for your ac service and the opportunity cost of time itself, because the big disadvantage of inverter ACs is the initial install. Instead of reusing the single hole left by your old single unit, you’ll need a different supply pipe to be fed from your roof down to your new inverter units. Meaning additional holes will need to be made in your roof to accommodate the pipe running in different locations. Generally, inverter installation will take longer due to its complexity. So rather than approximately two days of work for a conventional unit, you’re looking at three and a half days per inverter unit.

3. What about cost?

Some more good news about inverter units is that they are cheaper to buy. Manufacturers seem to be using a different business model for inverter units and are currently promoting them with a lower headline price than conventional ac units, in most instances.

4. Any hidden costs?

Spare parts for inverter units can be up to three times the cost of conventional ac unit parts. (That ‘different business model’ we spoke of probably doesn’t write this information into the initial sales pitch!) You will also be paying more for materials, what with all those extra pipes and labour, due to the extra days of installation. Finally, because brands in Dubai have to be sold through a representative’s office, and spare parts for inverters are more expensive, retailers here tend to hold much less of these parts in general because they would rather order on demand. This means you could wait a lot longer for your inverter parts to arrive when you need them.

5. Are there any installer malpractices to be aware of?

When making an investment in your home, a little bit of knowledge could save you significant headaches down the line. While some installers in the UAE follow strict protocol and take pride in their work, unfortunately not all can be described as reliable and scrupulous operators. Look out for these shortcuts and red flags that are typical of any company seeking to reduce their initial outlay and increase their profit margin – at your expense:

  • Changing AC Unit types without insulating the discharge gas pipe. To avoid both higher DEWA bills from cooling loss and damaged wet ceilings from condensation, your AC installer must insulate your gas pipes. As this can be timely and expensive, some (often cheaper) providers of conventional AC unit will skip this step and create refrigerated gas on the roof before it even enters the property. If insulation is missing from your installation quote, be sure to ask questions.
  • Cheaper supplied brand. If you’ve already received multiple quotes, you might be wondering how some providers can offer cheaper rates for the new AC units themselves. This is good news…. right? Not if they are supplying brands with either poor or very expensive parts supply. To reiterate our previous point, this is a sales tactic employed by some AC brands aiming to attract you with a ‘cheap to buy’ option that (unbeknown to you) is very expensive to maintain. You will spend much more in the long term, so beware!
  • Reusing old components. That old adage ‘what you don’t know can’t hurt you’ doesn’t apply here. Service providers doing a bare minimum job on your roof or in your ceiling is more common than you would expect – simply because they know they can get away with it. From cabling to isolators to contactors and gas pipes, they may try to reuse anything that isn’t already broken to save themselves money and increase profits. These parts can be as much as 20 years old in many Dubai communities, and as such, will be at the end of their useful life. If not replaced as part of your air conditioning upgrade, this will be the prime cause of AC failure, imminently!
