24 Hour HVAC Emergency Service

Nothing’s worse than a broken AC on a hot summer’s day! If you’re having this problem right now (or want to avoid it), here’s a list of the top air conditioner repair services in Ottawa!

In addition to that, we’ll also be bringing you some extra information like common AC issues, some answers to FAQs, and most importantly, the average costs to have your unit serviced.

Common Air Conditioner Issues

While you probably shouldn’t try to fix major issues yourself, it’ll help to know what the different issues your AC could be suffering from and what you can do while waiting for help to arrive.

1. Leaks

Depending on where the leak is happening, it could be one of these:

If there is a water leak indoors, it’s most likely that the drain system is either damaged and leaking, or clogged by some sort of growth. Either way, it needs to be cleaned or replaced.

If there’s a water leak happening outdoors, there could be a lot more reasons for it such as a dry air filter, the AC seal not done properly, or a broken condensate pan. Outdoor leaks could mean more serious issues, so it’s best to get this taken care of sooner than later.

The last kind of leak is a refrigerant leak. For major leaks, call a professional to have it looked at and decide whether or not you need to replace the system; a minor leak wouldn’t need the whole thing to be replaced.

2. Dirt and debris

Since there are so many parts to an AC unit, dirt could easily get stuck in different places and need cleaning once in a while. Here are a few:

The filter is responsible for making sure no dust and small particles enter your home through the AC unit. All you need to do is pop open your unit, pull it out, and remove the dust stuck in it.

It’s recommended to change the filter every 4 months. But if you have a pet, it’s best to change it every 2 months.

3. Frozen coil

The evaporator coil sometimes freezes—literally. Thaw out a completely frozen coil by turning off the AC unit and letting it be for the next 24 hours.

If the freeze isn’t too bad, switch your AC to fan mode and let it melt. Then call a repair service to make sure that no further damage has been done.

How Much Does Air Conditioner Installation Repair Cost in Ottawa

We’ve listed down the average cost of unit and installation as well as general repairs. Since AC units have many different parts, makes, and models, the actual cost will vary.

Air conditioner unit and installation$3,000 – $6,000
General repairs$413
