Just turned on my air conditioner... I suspect its gonna be a hot summer in Toronto.

Do you have central air? Are you suppose to "break in" the A/C after a long Winter? The first couple of times I just run it for an hour or two at night.
 
There is no "break in". It is not a car, nor does it have feelings nor does it need any foreplay! :eyebrows:

Just set the thermostat to cool and the desired temperature.

Here are a few Air Conditioning/Summer HVAC tips:

1. Set the thermostat temperature to the temperature you want. If you want 24C then set it to 24. It won't cool off any faster if you set it to 15. The thermostat is not a gas pedal. It is cruise control.

2. If you are away all day, it does in fact pay (costs less money in electricity) to dial back the air conditioning (set a higher temp) while you are not home, and then lower the temp when you get home. A setback thermostat is great if you have a regular routine. The new Nest or Ecobee or other internet enabled thermostats are good too if you want to lower the temp an hour or so before you get home so things are chilled down nicely.

3. If you have a basement, get a dehumidifier and attach a drain to run it into a floor drain. This will really help keep your basement dry and reduce risk of mold. It will also make for a nice dry, cool refuge!

4. If you haven't recently had your AC checked out, it is worth the $100 to have a guy come by to check the operation and freon charge.

5. If you have not already, think about washing the evaporator coil (inside the furnace duct) and the drain pan AND the condensate drain pan. These things get REALLY grungy and aside from the mold that can grow and get into your air (this is when people think they are "allergic" to air conditioning), cleaning the coil will increase the efficiency of your system. It can be a do-it-yourself job. Maybe check Youtube for a how to?

6. Rinse off the fins of the exterior condenser coils (outside your house).

7. Install a new furnace filter.

8. If you are away for the day, closing the curtains on south and west facing window will reduce passive heat gain and lower your electricity bills significantly.

9. Nowadays, with the cost of electricity going through the roof, it might be worthwhile checking out the newest high efficiency air conditioning systems. I think there are rebates from Hydro and the payback can be as little as a few years. One friend of mine got a high efficiency heat pump last spring and uses it to heat also most of the spring and fall and some warmer days in winter. I haven't done the math but he said that the energy cost per delivered btu/h is lower than natural gas until around -10C.

The only thing I have been told by an HVAC guy is to put the power on 24 hours before you plan to first run it, if you have actually turned off either or both of the inside and outside breakers over the winter.
 
Its a window unit in my small apartment. Cools it down quicky.

For cleaning, last year I got some stuff from Canadian Tire that I sprayed on the fins, it rinsed everything down and its nice and clean.

Luckily, I don't pay extra for my hydro, its all included in the rent, so I don't have to conserve energy so much.
 
Thinking about turning on the AC today, but it turned to not be so bad ... so far anyways.

I remember a few years ago turning the AC on in April for a few days !
 
A/C went on to auto earlier this week to maintain the house temperature, will be on to cool in the not too distant future if this weather keeps up. I don't track this sort of thing, but it does feel somewhat earlier than previous years...
 
Sunday, going out for Mother's Day wings, her choice. Had to crank up the AC in the car over and back. HAD TO.
 
Had PeakSaver installed on the AC last fall. Long story short, AC wouldn't fire up this last week. Called for AC service, was only getting 120V to the unit. Serviceman unhooked the PeakSaver and AC unit worked. Should I pass on the service call to my local utility who installed the PeakSaver unit?
 
I cover 3/4 of my outside central air unit during the 3 month non-cooling period.

Question: Can I leave the cover on and turn on the fan, just the fan?
