What to know about Air conditioner repair
Air conditioner repair calls tend to start on the first hot day of the year, when a system that sat idle all winter blows lukewarm air, refuses to start or trips its breaker. Most breakdowns trace back to a short list of parts, such as a capacitor, a contactor, a fan motor, a clogged condensate drain or a refrigerant leak, and a technician can often find the cause in a single visit.

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Type of system and fuel source
- Size and efficiency of the equipment
- Condition of the existing ductwork and venting
- Electrical or gas line changes
- Access to the furnace room, attic or outdoor unit location
- Removal and disposal of the old equipment
- Emergency or after-hours service
How to choose HVAC technicians in London
- Hire a technician who is licensed for heating, cooling and gas work in your province.
- For a new system, ask for a load calculation for your home rather than a size based on the old unit.
- Get written quotes that list the equipment, ductwork changes, removal of the old unit and any electrical work.
- Ask how they handle service calls and repairs after installation, including in the middle of winter.
- Compare the full scope of each quote, not only the equipment on it.
Questions to ask HVAC technicians before you hire
- Are you licensed for this type of heating, cooling or gas work in my province?
- How did you decide what size of system my home needs?
- Does this installation need a permit, and will you take care of it?
- What does the manufacturer's warranty cover, and what does your labour warranty cover?
- Will you need to change the ductwork, venting or electrical to make this work?
- Do you offer maintenance plans, and what do they include?
- How quickly can you respond if the system stops working?
Air conditioner repair permits in Ontario
Some air conditioner repair work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.

Common air conditioner repair questions
Is LokalMatch free for homeowners?
Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.
How many pros will contact me?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
