Need some Tips before calling for service
Prepare for the Winter
It's important this time of year to prepare your Furnace or Heating unit(s) to run lots of hours in the next 4 to 6 months. Whether you get a professional Heating tune up or tackle it yourself, here are a few items I suggest to save electricity, improve comfort and extend the life of your systems.
Our full Furnace maintenance check / tune up is $149 discounted until Feb 20th to $129. It includes checking refrigerant levels(Heat Pumps) and amp draws and component testing and lubricating what needs to be. And lots more that should be checked by a Licensed contractor(C-20).
Is only recommended for professionals. But here are the important musts if you choose to DIY. Please remember to always use caution, and GSC is not liable for anything said here. If you feel uncomfortable with DIY please do not attempt.
1.) Check all breakers and fuses for Heating and AC equipment making sure all is running.
2.) Outside at the condenser, with the unit off, remove any and all debris and brush from around the unit at least 2 feet. Use water hose without a spray nozzle the first time and spray the fins starting at the top and working your way down, do not spray directly into the fins. You should see dirty water coming out around the perimeter of the slab. Then, locate the end of the condensate drain if it terminates outside and make sure it is unobstructed.
3.) Inside locate all return or intakes and change the filters and make sure they are not obstructed. If you look behind the filters and it is quite dirty inside you should ask why. It may be that air is coming from wall or attic cavities and should be sealed. Next find your condensate drain line and locate the tee or vent near the furnace or air handler and add a cup of bleach or condensate drain tablets. Both help keep algae growth and bugs from stopping up the line. If you already have a clog you need to have the line cleared before adding chemicals.
4.) If you want to see if it is operating well turn it on and down 4-5 degrees below inside temperature and let it run for at least 10 minutes and check the closest supply duct's temperature. It should be 17-21 degrees cooler than the return or house temperature in cooling mode. Heat pumps can have higher degrees in heating if the heat strips are on and a Furnace will be usually over 25 degree difference.
If during this process you see, hear or smell anything unusual like water in secondary pans, vibrations, mold, mildew, rust, squealing, motor straining, or gas smell. I would call and let us check it out or do the full maintenance. A good tune up should cost more then $50, the reason why my tune ups cost $160 is because we will spent more then 1 hour cleaning and checking your equipment to make sure its the safest and most energy efficient that you can have.
Good luck with all your cleaning!
