AC Repair

AC repair costs in London typically range from $150 for a simple capacitor replacement to $800 or more for a compressor repair. Refrigerant recharges run $200–$500 depending on the type and amount needed. We always provide a written quote before beginning any work.

If the AC runs continuously but can't cool the home, the most likely causes are low refrigerant, a dirty air filter blocking airflow, a frozen evaporator coil, or a unit that's undersized for the space. It can also indicate that the system is aging and losing efficiency, we'll give you an honest assessment.

We recommend an annual AC tune-up in the spring before cooling season begins. Regular maintenance catches small issues before they become expensive repairs, keeps the system running at peak efficiency, and extends the lifespan of your equipment by several years.

Water around the indoor unit is almost always caused by a clogged condensate drain line. As the AC removes humidity from the air, it produces water that must drain away. When the drain line is blocked by algae or debris, water backs up and overflows. This is a quick fix but should be addressed promptly to prevent water damage.

If your AC is under 10 years old and the repair cost is less than 50% of a new unit, repair is usually the right choice. If it's over 12–15 years old, requires frequent repairs, or uses R-22 refrigerant (no longer manufactured), replacement with a modern high-efficiency unit will save you money on both repairs and energy bills.

A banging noise usually means a loose or broken part inside the compressor, such as a connecting rod or piston pin, and requires immediate attention to prevent further damage. Rattling often points to loose panels, debris inside the outdoor unit, or a failing fan motor. In either case, turn off the system and call us before running it further.

A repeatedly tripping breaker is a sign that the AC is drawing more current than it should. Common causes include a dirty air filter restricting airflow and causing the motor to overwork, a failing compressor that's hard-starting, a refrigerant leak causing the system to run longer cycles, or an electrical fault in the unit itself. Do not keep resetting the breaker without investigating the cause.

Most AC repairs are completed in a single visit of 1 to 2 hours. We stock common parts like capacitors, contactors, and refrigerant on our service vehicles so we can resolve the majority of issues the same day. If a compressor or coil replacement is needed, we'll schedule a follow-up visit once the part is sourced, usually within 1 to 3 business days.
