Compressor shorted to ground. (will need a new compressor).
Dirty furnace filter
Tripped AC Breaker (If your AC is not coming on I would suggest turning the breaker completely off and back on again to make sure the breaker is on. Do not touch anything metal on your circuit breaker box for safety).
We have this questions asked many times over the years and I want to post my response to this frequently asked question: I am so sorry to hear that you have spent all this money and still do not have a furnace and air conditioner that are working properly! I have this problem asked many times over the years and my answer is: I would strongly recommend that you have your HVAC contractor do a Manual J Heat Gain and Heat Loss calculation on your home before installing a new furnace or doing any other work. We are required here in Louisville, KY to submit a Manual J calculation to the Housing Department, Code enforcement before a permit will be issued to start a new installation. Without the Manual J calculation, it would be a guess as to what size equipment needs to be installed and this is why many people get the wrong size equipment. Requiring a heat gain, heat loss calculation protects the homeowner from getting the wrong size HVAC equipment installed. Most companies have a Manual J computer program where they enter the required information like the home’s orientation (facing north, south, etc.) the amount of insulation, window types, door types and all surfaces that gain or lose heat and more. The computer program will figure the amount of heat loss and gain and tell the contractor what size HVAC equipment needs to be installed. I would recommend that you get this Manual J calculation completed for your home so you know for sure that you are getting the right sized HVAC equipment installed. Even though it is a pain and extra expense for the homeowner and contractor this insures the right size equipment is installed and is invaluable for protecting your energy bill and comfort.

We have many customers ask how to find a low voltage short when the low voltage transformer is burning up or the fuse on the control board constantly blows? Most of the time I have found that shorts occur in the thermostat wires that go out to the outdoor condensing unit. Wear and tear of sun light, animals or weed eaters usually cause these shorts. I would suggest inspecting the thermostat wires for cracks, wear and tear. Pay close attention to where the thermostat wires go through the body of the furnace or air conditioning unit. Many times the thermostat wires will short out against the body of the furnace or air conditioner. I found this real good Youtube video on how to find low voltage shorts by ACservicetech. I hope this great Youtube Video will help you out in finding where the short is located. Thanks so much to ACservicetech for making this great video!

Problem: The pilot on my furnace will not stay lit after we had a new roof installed. The only changes I’ve made are: New cheap $1.58 furnace filter (30-day) Ace Hardware, New roof and New roof vents (my attic is SO windy compared to before) Maybe the roofers disconnected the furnace vent in attic and it’s causing a back-draft? Thanks greatly for any help. I’m very desperate! Lori
1. Many times the roofers knock, sand off the shingles, dirt or rust on to the burners or into the pilot light and the pilot and burners need to be cleaned to work and burn properly. You should have a nice blue flame that encompasses the thermocouple. If the flame is not blue or not strong you probably need to clean the pilot. If the pilot is yellow the pilot needs to be cleaned.
2. Rust or dirt that falls on the burners can cause delayed ignition which would be like a mini explosion when the furnace tries to light. This could cause the pilot to blow out when the furnace ignites. This usually happens when the furnace tries to light after it has been off for a while (furnace is cold).
3. Check the furnace when the burners are on and make sure they are fully burning a blue flame from the front to back all the way. If not then the burners might need cleaning, the vent could be stopped up or if not burning properly only when the blower is on then this would be a sign of a heat exchanger leak.
4. Check to make sure that the hot gas is all going up your vent stack through the roof by feeling around the bonnet where the vent attaches to the furnace. If any heat is coming out around the bonnet when the gas is burning on your furnace then your furnace is not venting properly and you need to turn it off because this can be dangerous. Need to get the vent fixed.
5. The furnace and water heater vent as you know should run a couple of feet above the roof and not terminate in the attic. This is dangerous if it vents up in your attic. I could cause a fire or allow carbon monoxide into your home.
I hope this gives you some things to look for. I hope you can easily and inexpensively find and fix the problem. I hope all that the furnace needs is a good cleaning. Thanks for asking this question!
