Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner varieties, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC systems.

  • Central AC: These are the most common home air conditioners, offering precise, consistent temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to different rooms in your home.
  • Window ACs: Window air conditioners are a popular choice for Ontario condos, townhomes, and apartments. These compact, affordable units are designed for cooling small spaces and single rooms, and they fit snugly in a window frame or dedicated wall slot. Many window-mounted air conditioner users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Split ACs: Split AC units have two main elements: one indoors and one outdoors. They provide quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name suggests, portable air conditioner units don't require permanent installation or ductwork. Instead, they remove hot air through an exhaust hose connected to a window or nearby vent. They're preferred for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-split AC units have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.

How to Choose Your Ontario AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before hiring a repair company, it's important to take the time to research if they're ideal for your dwelling. Here are a few essential steps to follow.

Confirm the Company Is Properly Licensed and Insured

California HVAC contractors need a C-20 (Warm-Air Heating, Ventilation, and Air-Conditioning) license from the Department of Consumer Affairs. The application process involves comprehensive exams on business law and practical skills.

Many states and cities also require companies to carry liability insurance. Even if your community doesn't require it, we still recommend choosing an insured company. This will protect you if an accident happens or something gets damaged.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that handle complaints professionally and honor their warranties.

It's common for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a provider if most reviewers had subpar experiences.

Compare Estimates

Obtain at least three detailed, written estimates from different companies for the best deal. A good estimate should include additional fees such as permitting costs. You should also ask about installer guarantees, the emergency repair process, and manufacturer warranties.

Frequently Asked Questions About AC Repair in Ontario

What's the cost of an AC repair job in Ontario?

Your AC system repair costs will hinge on the type of unit you have and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like changing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$62–$165
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$83–$207
Refrigerant leak$400–$1500
Frozen condenser coils$1,241–$3,722
Fan or air blower issues$150–$200
Compressor replacement$600–$1,571

What month is best for getting an air conditioner replaced?

To find the best time for your installation, consider both the local weather and company demand. Generally, contractors are more occupied as the climate warms up and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

How long is my air conditioner's lifespan? When should I consider a replacement?

With adequate maintenance, your air conditioner's lifespan could be 10-15 years. Remember that parts frequently become obsolete as time goes on. If your servicer can't find a critical replacement part, you might need to consider getting a new air conditioner.

What industry certifications should I look for when researching Ontario AC repair companies?

Private accreditations might not be required, but firms that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).

How quickly can an HVAC company in Ontario respond to emergency repair requests?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. A number of companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the contractor directly is best so you can get the most accurate information.
