AC Installation Toronto

There are plenty of excellent AC unit brands out there, but what really makes the difference in an air conditioners’ reliability is how well it was installed. The very best brands are choosy about who they allow to install their equipment.

We only allow licensed, professional technicians that receive certification directly from the manufacturer to install your new air conditioner. Whenever there are updates or new models, we get training and workshops on how the units work best.

What this means for you is that you’ll be getting your air conditioner serviced by skilled technicians who have the most comprehensive understanding of your specific unit.

Air Conditioning Maintenance Toronto

Without regular air conditioner maintenance, your AC unit won’t have the same energy efficiency as it should. Tune-ups to the evaporator coil and condenser coil, and making adjustments to the settings based on your usage, will help ensure your unit isn’t working any harder than it needs to – and isn’t wasting electricity.

Regular maintenance is an essential part of a long-lasting AC system. Toronto homeowners can trust our comprehensive yearly maintenance services, which are designed to keep your AC units running smoothly all year round. 

Don’t wait until you hear strange noises coming from your AC unit! Regular maintenance will alert you to any parts that should be replaced, or any issues that could become worse over time. Catching a problem early allows a professional technician to stop a potentially huge problem before it has time to develop.

Repair vs. Replace Air Conditioner

Deciding whether to repair or replace your air conditioner depends on several factors. A surprisingly simple way of determining if it’s better to replace or repair your AC unit is to multiply the unit’s age by the cost of repairs. If the total exceeds $5,000, it’s a good idea to replace it.

Newer air conditioners are also generally more energy-efficient than older models, which can lead to lower utility bills and greater comfort. If your current unit is outdated and inefficient, replacing it with a newer model could result in long-term savings on energy costs.

If your air conditioner requires frequent repairs or is experiencing recurring issues, it may be a sign that it’s reaching the end of its lifespan. Constant repairs can be costly and inconvenient, so replacing the unit may be a more reliable solution in the long run. 

Common AC Issues

Common AC issues can crop up due to several reasons, including faulty installation, poor quality work on maintenance, or a system that’s nearing the end of its life and in need of replacement. 

If you’re in need of air conditioner repair, it might be due to these common causes: 

  • Refrigerant leaks
  • Dirty or clogged air filters (due to inadequate maintenance)
  • Sensor or thermostat problems
  • Electric control failure
  • Drainage problems

If you’re hearing unusual noises or not getting the cool air that you need, our technicians can quickly diagnose the issue for you. In some cases, they can make repairs on the same day, getting you out of the heat and back into comfort.

What to Expect with Hoerner

We believe that making an informed decision on a new air conditioner shouldn’t be a painful process.

Replacing your air conditioner isn’t easy. In fact, it can get overwhelming very quickly. For instance, what size do you need for your home? What energy efficiency rating will pay off in long term savings? Air conditioners come with different features and benefits, and not every one is right for everyone.

We provide both central air conditioning systems and ductless systems that are perfect for older homes without ductwork. If you prefer, we can also install custom ductwork for you.

We believe that making informed decisions shouldn’t be a difficult process. Our friendly team is ready to equip you with the information you need in order to make an informed decision. We explain everything in everyday terms, so you aren’t overwhelmed with a lot of tech-speak.
