AC Installation & Repair
Ottawa summers can be more humid and intense than people expect. We install and service central air conditioning systems sized correctly for your home's square footage and duct layout, so you get even cooling without the short-cycling and high bills that come from an oversized unit.
Signs you might need this
- AC is blowing warm or barely cooling the house
- Ice forming on the indoor coil or refrigerant lines
- Unit is short-cycling or won't turn on at all
- System is 12–15+ years old and getting noisier or less efficient
