Repair or maintain air conditioning
Here are some articles and pricing guides on Repair or maintain air conditioning
Price guide
AC recharge cost
A home air conditioner should not need regular refrigerant top-ups. Because the system runs in a sealed loop, needing a recharge almost always means there is a leak somewhere in the line. In Canada, the average AC recharge cost ranges from $150 to $800 depending on the refrigerant type and the size of the project, with older R-22 systems costing considerably more than newer R-410A, R-32, or R-454B units. This guide covers air conditioner recharge cost by refrigerant and system type, what drives the price, and when a recharge makes more sense than a repair or full replacement.

Air Conditioner Not Cooling
When your air conditioner is running but the house keeps getting warmer, the problem is not always obvious. Some causes are simple enough to fix yourself in minutes. Others point to a failing component that needs a pro. This guide walks through the most common reasons an air conditioner will not cool your home, what to check on your own, and when it makes sense to call someone in.
Price guide
Cost to service air conditioning unit
Whether for an older system or to prepare a newer unit, knowing the average cost for air conditioning service helps you compare quotes and avoid paying more than necessary. The cost to service an air conditioning unit in Canada typically ranges from $100 to $300 for a standard annual tune-up, with more involved servicing such as refrigerant recharging or coil cleaning running $150 to $500 depending on the work required. Air conditioning service costs vary based on the type of system, the age of the unit, and whether any parts or refrigerant need to be topped up or replaced. This guide covers what a typical air con service price includes, what drives costs up, and what to expect when booking a pro for routine maintenance versus a diagnostic visit.
Price guide
