Home Cooling Repairs Done Right

Being able to identify when your home's air conditioner isn't working the way it should is essential in preventing further damage from occurring. Here are some common signs to look out for:

Strange smells and odd sounds are coming from your cooling appliances as it operates.
Your cooling system keeps short-cycling.
Your indoor air quality has diminished.
There is pooling water or refrigerant around your outdoor unit.
Your thermostat is giving you incorrect temperature readings.
You notice a substantial increase in your monthly utility bills, even though you haven't used your AC system any more frequently.
There's warm air blowing into your home.
There's no air coming from your air conditioning system.
Your air conditioner won't turn on.

Running your AC in this type of condition can strain the system and potentially lead to further damage. By partnering with trusted, pre-vetted technicians from our Thunder Bay network, you can have peace of mind knowing that your repairs are being done the right way--with thorough diagnostic testing that pinpoints the underlying cause, rather than the symptom. You'll get a fully functioning, energy-efficient cooling system that once again meets your indoor comfort needs.

Equipment lease-to-own contracts will have a total term of 180 months.
