Air Conditioning Services

Whether you have a central air conditioning system or need a new cooling system, our team of professionals can help you with installation, regular maintenance or AC repairs. Don’t get caught in a middle of a heatwave without a way to stay cool.

We can be reached 24/7 for emergency repairs if you need immediate assistance. Whatever you need, our team of Calgary’s best is here to help.

For over 40 years, Knight has been working hard to create the kind of air conditioning service we would want our own friends and families to use.

What Is the Most Common AC Repair?

When cooling systems make strange noises, start leaking or begin to smell bad, it’s time to call in the professionals. At Knight, we tackle a lot of air conditioning repairs and pride ourselves on our ability to diagnose and fix common AC problems like these quickly:

There are many possible reasons an air conditioner might freeze up. If you see ice on the condenser coils, call Knight. We’ll determine if the fix is as simple as replacing a dirty air filter that has been left unchanged or if a more serious mechanical issue exists.

When your air conditioner isn’t properly cooling your home, the technicians at Knight will do some sleuthing for you. We’ll investigate potential thermostat problems, check the refrigerant levels, inspect the motor, and even peek into your ductwork.

Are you loving the cool breeze your AC provides but feeling nauseous from the stink that accompanies it? As you can imagine, your indoor air quality is negatively impacted when you detect bad smells emanating from your air conditioner. It could be a refrigerant leak, mould build-up from a water leak, or another cause. Whatever it may be, Knight will eliminate the source of the smell for you.

An air conditioner that runs continuously requires a lot of energy and puts undue wear and tear on your HVAC system. Something is causing it to work overtime—it could be cool air escaping somewhere, or the thermostat may be on the fritz. Regardless, don’t wait long to address the problem because it’ll likely lead to expensive repairs down the road.

Do I Need to Install a New Air Conditioner?

You may be wondering if you should continue to repair your air conditioning unit or install a new one. Here are a few telltale signs it is time for a replacement:

If your air conditioner is 15-20 years old, you are due for replacement. Knight can give you honest recommendations for newer models that are more energy efficient and function better.

Check your Seasonal Energy Efficiency Ratio (SEER) rating, which measures maximum efficiency. Older AC models often have low average SEER ratings of 8 or 9. Modern AC units, on the other hand, have SEER ratings that range from 13-25. Knight can help you find the right AC unit for your size home—and budget.

How many air conditioner repairs are you dealing with? Owning an AC in Calgary that always needs service is not only frustrating, but it also can be quite expensive.

If your cooling system just isn’t keeping your home cool and comfortable anymore, it’s time to investigate an upgrade.

New AC System Installation

If you want a home that is a cool, refreshing oasis from the heat of the summer, Knight can help. We install a variety of air conditioning systems and can recommend the right model for you based on:

  • Your home’s square footage.
  • Your energy efficiency requirements.
  • Your need for precise cooling control in different zones of your home.
  • Your budget.

Why suffer with a window unit? Central air offers cool comfort using your existing forced-air ducts for your furnace and can work with your existing thermostat or with a new state-of-the-art wifi thermostat model.

AC System Tune-Ups

Did you know that air conditioners work better with regular maintenance? It’s one of those things that people should do but often forget. Like most people, you probably haven’t considered the real advantages of getting your AC checked and tuned:

  • You will help prevent breakdown situations.
    Your Knight can identify problems before they become emergencies (you just know that breakdown will happen on the hottest day of the year!).
  • You will get a system that runs as efficiently as possible.
    Properly tuned AC systems will use less energy – which will count when the time comes to open your electricity bill.
  • You’ll get a system that lasts longer.
    Your technician will identify and fix small parts issues before they can result in wear and tear that stresses the whole machine. With air conditioner tune-ups, you’ll get more years of good service out of the system you already own – and postpone paying for a new one.

Every Knight technician is a Calgary cooling services expert, ready to provide you with air conditioning tips and tricks that’ll keep your system running all season long. And we’ll do everything possible to make our visit to your house a positive experience; we arrive on time, provide the full price of any work we do upfront, and use mats and shoe covers to keep your home clean.
