Serving homeowners throughout London and the surrounding area, we work to restore your comfort quickly and efficiently so your air conditioning system performs reliably all summer long.
Refrigerant Leaks
One of the most common reasons homeowners in London require air conditioner repair is a refrigerant leak. Even a small loss of refrigerant can significantly reduce your AC system’s efficiency and cooling capacity. When refrigerant levels are low, your air conditioner must run longer to keep your home comfortable, leading to higher energy bills and increased wear on the system. During periods of hot summer weather, your AC may struggle to maintain the desired temperature altogether.
While it was once common to simply “top up” refrigerant levels, current environmental regulations require HVAC technicians to locate and repair the leak before adding refrigerant to the system. Professional air conditioner service ensures your system operates safely, efficiently, and reliably throughout the summer months in London.
Damaged Wiring
Damaged or loose wiring can also be an issue. Over the winter months in London, Ontario, mice and other small rodents can build nests within the AC unit that sits outside. Some older AC models have little heaters in the compressors that run during the winter. The warm environment inside the unit is very attractive to small rodents. They can disturb the wiring or chew on the wires, causing a short.
Common Issues with Older AC Units
As the unit gets older there is a greater probability that there will be a failure of the contactor, capacitor, condensing fan motor or even the compressor.
London, ON - Homeowner Tips
A dirty condenser coil (the outside unit) can negatively affect your air conditioner’s performance. Dirt, dust, plant pollen and leaves can build up on the coil, reducing the transfer of heat from the refrigerant to the outside air. Since the unit is outside exposed to the elements, it is necessary to clean it periodically. Don’t allow nearby bushes to grow around your air conditioner. The unit needs good air flow to operate correctly.
In London, it’s important to change your furnace filter before the cooling season and check it regularly.
The fan in your furnace is required to:
- Circulate the cool air produced by your air conditioner throughout your home.
- Maintain a sufficient flow of air over the coil installed in the ductwork.
A dirty furnace filter can result in reduced performance of your AC and lead to coil icing. There are other causes and remedies for icing that you can read about on our blog about icing.
