When it comes to A/C troubleshooting, the source(s) of trouble for your air conditioning system could be one or more of a number of factors. For starters, check your thermostat; It could be possible that the air conditioner itself is working fine, but isn’t getting the right commands from the thermostat, which could either have low/dead batteries, not properly programmed or experiencing other issues. There are also disconnect switches for your A/C, both inside and outside, so make sure these are in the ‘ON’ position. The A/C could have overloaded or triggered the electrical system, resulting in a tripped circuit breaker, blown fuse or blown transformer. Or you may need to change your filter, clean your A/C coils, or repair the starting components or blower. The best way to find out is to contact Advanced HVAC for air conditioner repair in Ottawa.
