Enjoy The Best A/C Brands

Brand matters. When you shop at Constant, you get access to credible suppliers and manufacturers. You can expect high-performing products that come with amazing warranties. Which A/C brands do we stock?

  • Lennox
  • American Standard
  • Daikin
  • Armstrong

What to Consider When Buying a New A/C


Ready to beat the heat? You’re not alone! Remember that it’s very important to choose the right unit. A system that’s too small will not be able to keep up with your cooling needs, whereas one that is too large will cool the space too quickly, thus not having enough time to extract the moisture. The result? You will be left with clammy and cold interiors.


We often get asked: What should I look for when buying an air conditioner. Below, we’ve compiled a list of the factors you should look at when purchasing a new air conditioner.



A room that is smaller than 150 square feet will require a 1-ton air conditioner to provide sufficient cooling. A room that is between 150-180 square feet will need a 1.5-ton air conditioner. A room that is bigger than that will require a 2-ton A/C. Getting the size right is crucial. This optimizes performance and helps to cut costs.



Purchasing a unit that uses less energy to cool your interiors is ultimately what you’re looking for. You have to look at the A/C’s EER which stands for the “Energy Rating Efficiency.” The higher the rating, the better. This means that your A/C won’t guzzle energy and leave your rooms cold and uncomfortable.

Central or Ductless?

Central or Ductless?

To decide this, you must look at your home’s ductwork and air handler system. For instance, a central air conditioner sends the cool air via the air handler on your furnace and then into your ductwork. After which, it is carried to the remainder of your house. A ductless unit utilizes thin cables that sit between the condenser and a box on your wall. That is, no ductwork is involved and no vents are required on the floor.

Air Quality

Air Quality

Irrespective or the air conditioner’s model and type, you have to pay attention to IAQ (Indoor Air Quality). The unit must have a great dehumidifier that brings down humidity levels while cooling the air. This greatly elevates your overall comfort levels. You will need to inspect the filter and make sure it’s up to par. A well-performing filter cools better and prevents the evaporator from getting clogged with dust.

Good Installation

Good Installation is Key

Did you know – How your air conditioner performs hugely depends on its installation. This is why it’s recommended that you get your A/C installed by an authorised dealer or HVAC professional. Your technician will also inform you of the basic precautions you must take to clean and maintain your A/C. After installation, it’s advisable to get your unit serviced at least once every quarter.

Say No to Noise

Say No to Noise

This one is a no brainer but we thought we’d throw it in here just in case! Pick a unit that runs quietly and smoothly. Anything that emits between 19-60 decibels of noise is ideal. It’s also crucial to keep an eye on the cooling speed. If the thermostat offers two fans and variable speeds, you have the option of choosing a different setting for different hours of the day.

Insulating Materials

Insulating Materials

You need an A/C that comes with the right insulation materials with clear instructions. This will help you seal the area around the unit properly and reduce leakages.

Don’t Ignore These 5 Red Flags

Repair Your A/C ASAP


Just like any other system in your home, your A/C will call for a little TLC every now and then. There are certain warning signs that point to a risk of breakdown – costing you a tidy sum in the long run. To ensure that this doesn’t happen to you, we’ve summarized the main red flags you should watch out for;


  • The A/C is blowing out warm air or no air at all when you switch it on
  • The A/C is emitting loud clangs and thuds
  • The A/C produces excess moisture or leaks
  • The A/C emits strange odours
  • There are high humidity levels in your home

Cost for A/C Repair and Installation

When you come to Constant, expect the best quotes – every single time!

How much does it cost to fix an air conditioner? It all depends on the brand and whether yours is a packaged system. Usually, repairing minor parts could cost anywhere between $600 to $2000.

If you decide that your system is beyond help and are looking to replace it, you may be wondering; how much is a 13 SEER air conditioner? A 13-14 SEER A/C and coil can rake up an estimate of $1,435. If you’re factoring in the installation cost for the A/C and coil, you’re looking at an additional $2,770. This brings us to a total estimate of $4,205 for a new 13 SEER air conditioner system.

When should I replace my A/C? Replacement is only advisable if your A/C is over 8 years old and the cost of repair is more than 50% of the cost of a brand new unit.
